Abstract

An injector nozzle for equipment for injection moulding of plastic materials has a nozzle tip (4) with an internal hollow element (5) and an external hollow element (6), which are connected to the body (1) of the injector nozzle in an independent way and defined between which is a space of mutual separation (11) . The internal hollow element (5) and the external hollow element (6) have respective axial portions (5c, 6a) in contact with one another, without, however, preventing the internal hollow element (5) from being screwed to and unscrewed from the body (1) of the injector nozzle independently of the external hollow element (6) .

Description

"INJECTOR-NOZZLE TIP FOR EQUIPMENT FOR INJECTION MOULDING OF PLASTIC MATERIALS"
* * *
Background of the invention The present invention relates to injector nozzles for equipment for injection moulding of plastic materials, of the type comprising a body having a central passage and a nozzle tip including an internal hollow element made of a material with high thermal conductivity and an external hollow element made of a material with lower thermal conductivity. State of the prior art
An injector nozzle of the above type is described and illustrated, for example, in the document No. EP-B- 0633118, according to which the external hollow element has, at one end, a thread that can be engaged on a corresponding thread of the body of the injector and, at the opposite end, a part for sealed contact with an injection mould, operatively associated to which is the injector nozzle. The internal hollow element is set between the central passage of the body of the injector nozzle and the external hollow element, and is blocked and withheld with respect to the body of the nozzle by the external hollow element itself, which thus functions as member for axial retention of said internal hollow element. Blocking of the internal hollow element is hence entirely entrusted to proper gripping of the external hollow element with respect to the body of the injector nozzle: in the case of incomplete or in any case insufficient screwing, the internal hollow element is consequently not properly blocked, which can cause, during operation of the injector nozzle, moulding imperfections.
A similar solution is likewise described and illustrated in the document No. WO-03/028974. Known from the document No. EP-A-1321274, filed in the name of the present applicant, is an injector- nozzle tip of the type defined at the beginning of the present description, in which the internal hollow element is connected to the body of the injector nozzle independently with respect to the external hollow element. The two hollow elements are provided with respective threads, engaged independently to corresponding threads of the body of the injector nozzle. Defined between the external hollow element and the internal hollow element is a space of mutual separation, which determines a gap as a result of which there is no direct contact between the internal hollow element and the external hollow element. This enables a reduction in the transmission of heat from the injector nozzle to the mould to which it is associated. Summary of the invention
The present invention has the purpose of improving the injector-nozzle tip known from the aforesaid document No. EP-A-1321274, and said purpose is achieved thanks to the following combination of characteristics:
- the internal hollow element is connected to the body of the injector nozzle independently with respect to said external hollow element via a threaded coupling;
- between said threaded connection and said space of mutual separation said internal hollow element has an axial portion in contact with a corresponding axial portion of the external hollow element; and - the contact between said axial portion of the internal hollow element and that of the external hollow element is such as to enable said internal hollow element to be screwed to and unscrewed from the body of the nozzle independently of said external hollow element. The axial portion of the external hollow element conveniently has an external thread screwed within a corresponding internal thread of the body of the injector nozzle. Thanks to this idea of solution, on the one hand it is guaranteed that the internal hollow element of the tip is kept engaged to the body of the injector nozzle irrespective of whether the external hollow element is more or less screwed in said body, unlike the solution according to the already cited document EP-B-0633188, in which, as has been said, retention of the internal hollow element is entirely entrusted to proper screwing of the external hollow element with respect to the body of the injector nozzle. On the other hand, the contact without retention between the axial portion of the internal hollow element and that of the external hollow element enables proper centring of the two components with respect to one another and with respect to the central passage of the body of the injector nozzle. ' Said centring is particularly important in the case where the injection hole within the mould to which the injector nozzle is associated in use is made directly in the external hollow element. In any case, since the internal hollow element is centred on the central passage of the body and the external hollow element is centred on the internal hollow element, the three components are perfectly aligned to one another so as to guarantee an optimal coupling with the mould and hence better performance and constancy of moulding efficiency. With the solution according to the already cited document EP-A-1321274 it may in some cases happen in fact that the space of mutual separation between the external hollow • element and the internal hollow element is not perfectly uniform, and even that the internal hollow element may be in contact with the external hollow element or with the mould in the area of its free end, which could cause considerable thermal dissipation and moulding imperfections. Furthermore, thanks to the fact that the external hollow element is screwed within the body of the injector nozzle (unlike the solution according to the document No. EP-A-1321274) , the further advantage is achieved of being able to prolong the electrical heating resistor or resistors, applied on the outside of the body of the injector nozzle, until they come to be immediately adjacent to the point of injection within the mould. This guarantees a better heating of the point of injection and prevents formation of cold points that could lead to defects of the moulded pieces and consequent rejects. Furthermore, the possibility of heating in an optimal way in the proximity of the point of injection ensures a lower energy consumption, unlike the case where the thermal source (heating resistor) is located at a greater distance and a greater power is hence required given the same temperature. Brief description of the drawings
The invention will now be described in detail with reference to the annexed plate of drawings, which is provided purely by of way of non-limiting example, and in which:
- Figure 1 is a schematic illustration of a longitudinal section of the tip part of an injector nozzle according to the invention for equipment for injection moulding of plastic materials; and
- Figures 2 and 3 show, respectively, a first and a second variant of the injector nozzle according to the invention.
Detailed description of the invention The injector nozzle represented in Figure 1 is in itself as a whole generally known, and consequently will not be described in detail. For the purposes of the invention, it is sufficient to clarify that the injector nozzle ,is inserted in a seat S of a mould M for injection of plastic materials, the cavity of which communicates with the seat S through an injection hole or pipe D.
The injector nozzle has a body 1 with a central axial passage 2 for the plastic material to be injected, which is aligned with the injection pipe D and along which there is axially mobile a pin 3 cooperating as open/close element with the injection pipe D.
The injector nozzle 1 has, on the side facing the injection pipe D, a nozzle tip 4 formed by an internal hollow element 5 made of a material with high thermal conductivity (typically copper) , referred to as prod, and by an external hollow element 6 of a material with lower thermal conductivity, for example, made of steel or titanium, referred to as ferrule.
The internal hollow element 5 has an axially internal portion 5a and an axially external portion 5b, which extends beyond the external hollow element 6 and through which the free end of the pin 3 moves. The external hollow element 6 has, in turn, an axially internal portion 6a and an axially external portion βb, which is conveniently elastically deformable, the outer surface of which is in contact with the mould M.
The internal hollow element 5 and the external hollow element 6 are fixed to the body 1 of the injector nozzle autonomously and independently of one another: for this purpose, the internal hollow element 5 has, in its axially internal portion 5a, an external thread 7 screwed in a corresponding internal thread 8 of the body 1, and likewise the external hollow element 6 has, in its axially internal portion 6a, an external thread 9 screwed within a corresponding internal thread 10 of the body 1.
Designated by 13 is a generally helical groove formed on the outer surface of the body 1 and designed to house in a known way one or two electrical heating resistors (not illustrated) . Owing to the fact that the external hollow element 6 is screwed within the body 1 of the injector nozzle, the electrical heating resistor or resistors housed in the groove 13 will extend until it is or they are immediately adjacent to the point of injection within the mould D.
Between the outer ends 5b and βb of the hollow elements 5 and 6 is an annular space of mutual separation, which defines a gap for thermal insulation 11.
Between the thread 7 and the gap 11, the internal hollow element 5 and the external hollow element 6 are in contact with one another: more in particular, at a certain axial distance from the thread 7 the internal hollow element 5 has an axial generally central portion 5c, which has an outer diameter equal to or preferably greater than that of the thread 7 and the outer surface of which is in contact with the inner surface of the axial portion 6a of the external hollow element 6.
The contact between the axial portions 5c and βa is such as not to constitute a constraint for the internal hollow element 5 by the external hollow element 6: in other words, the contact between the axial portions 12 and 13 is such as to enable the internal hollow element 5 to be screwed to and unscrewed from the body 1 independently of the external hollow element 6. This guarantees that the internal hollow element 5 will remain properly connected to the body 1 through the threaded connection 7-8 irrespective of whether the external hollow element 6 is more or less screwed to the body 1 through the corresponding threads 9 and 10.
The variants represented in Figures 2 and 3 are generally similar to the embodiment illustrated in Figure 1, and only the differences will be described in detail in what follows, using the same reference numbers for the parts that are identical or similar.
In the case of Figure 2, the axial portion 5c of the internal hollow element 5 has a prolongation 5d axially set between the threaded connection 7, 8 and the axial portion 6a of the external hollow element 6. Said prolongation 5d faces a corresponding internal annular centring surface 12 of the body 1, with which it is in contact. In this case, the axial length of the internal hollow element 5 is appreciably greater than that of the external hollow element 6 according to Figure 1, which enables said internal hollow element 5 to receive a greater amount of heat from the body 1. In addition/ centring between the surfaces 5d and 12 on the one hand and between the surfaces 5c and βa on the other hand guarantees a perfect alignment between the hollow elements 5, 6 and the central passage 2 of the body 1, and hence a more accurate assembly and a better constancy of operation of the injector nozzle. The variant represented in Figure 3 differs from that of Figure 2 only in that the injection hole or pipe D is formed directly in an axial appendage βc of the external hollow element 6.
Of course, the details of construction and the embodiments may vary widely with respect to what is described and illustrated herein purely by way of example, without thereby departing from the scope of the present invention, as defined in the ensuing claims.
