According to the middle-pressure resin bus heat dissipation hole casting mould disclosed by the invention, the shape size precision and the position precision of the heat dissipation hole can be accurately guaranteed and the de-molding is very convenient.
Description
Technical field
The present invention relates to a kind of resin bus casting mold, specifically a kind of louvre mould for cast pressurizing resin bus.
Background technology
Resin bus obtains using more and more widely in domestic and international market because excellent barrier propterty in recent years, not only is used in the low-voltage bus bar field, and is also applying gradually in middle pressure bus field.But the pouring technology of middle pressurizing resin bus is very complicated, and one of them difficult point is: middle pressurizing resin bus is distributed with uniform louvre between phase and phase, and this louvre is the through hole of a surrounding sealing, there is no draw taper, and shape and size are required accurately; Casting complete, after resin solidification, mould is embedded in the resin of curing, due to the pressure that expands mould is produced in the cohesive force of die surface and resin and resin curing process, causes mould to be difficult to extract out from resin.
Application number is 200620148015.3, and publication number is that the Chinese invention patent of CN200981099Y discloses a kind of bus-bar radiation hole mould core structure, adopts the good material of elasticity as the mould heart, by magnetic element, mould is positioned on metal mold.Although this structure has solved demoulding hard problem, but there is following shortcoming: 1. because the mould heart is the hollow cylindrical shell that elastomeric material is made, be subject to the pressure that resin gravity produces during cast, very easily distortion causes the louvre geomery pouring into a mould out undesirable; 2. because this structure adopts magnetic element location, and if the magnetic location runs into mechanical oscillation in process of production, be easy to cause the disengaging of magnetic element and metal mold, lose positioning action, the louvre position that causes pouring into a mould out is undesirable.
Summary of the invention
Goal of the invention: the present invention aims to provide a kind of louvre mould for cast pressurizing resin bus, not only can guarantee accurately geomery and the positional precision of louvre in bus, and the demoulding very easily.
Technical scheme: a kind of middle pressurizing resin bus louvre casting mold, comprise outer field elastic overcoat, wherein, described elastic overcoat inside is provided with the metal core rod.
Above-mentioned middle pressurizing resin bus louvre casting mold, wherein, described elastic overcoat is shaped as a hollow cylindrical shell, makes by having flexible material.
Above-mentioned middle pressurizing resin bus louvre casting mold, wherein: the outer surface of the inner surface of described elastic overcoat and described metal core rod has identical gradient.
Above-mentioned middle pressurizing resin bus louvre casting mold, wherein: described metal core rod top is provided with handle.
Above-mentioned middle pressurizing resin bus louvre casting mold, wherein: the bottom of described metal core rod is provided with locating hole.
Beneficial effect: the present invention is divided into two-layer, outer overcoat for the elastomeric material making, and internal layer is the metal core rod, the metal pattern stud is lived elastic overcoat, to guarantee the shape and size precision of louvre; The core rod bottom is with locating hole, and the alignment pin bottom metal mold coordinates, and guarantees the accurate location of louvre mould; The inner surface of overcoat and the outer surface of core rod are the inclined-plane that cooperatively interacts, first the metal core rod is extracted out from overcoat when conveniently stripped, after core rod is extracted out, available power perpendicular to the louvre surface makes overcoat produce strain, thereby peel off with resin, then overcoat is extracted out from the resin that solidifies, completed the demoulding.
Because the elastic overcoat inner support of louvre mould of the present invention has the metal core rod, so can guarantee the shape and size precision of louvre; The locate mode of alignment pin and locating hole can guarantee the accurate location of louvre mould; The inner surface of overcoat and the outer surface of core rod adopt the inclined-plane to coordinate, and the metal core rod first can easily be extracted out from overcoat when making the demoulding, and the elasticity of overcoat can easily be peeled off overcoat from resin, be convenient in demoulding thereby make.
Below in conjunction with accompanying drawing, the present invention is further described:

The specific embodiment
Middle pressurizing resin bus louvre mould involved in the present invention is as shown in Fig. 1 ~ 3, comprise double-layer structure: the metal core rod 2 of outer field elastic overcoat 1 and internal layer, described elastic overcoat 1 has the inner surface 1a with gradient, described metal core rod 2 is with the outer surface 2a of corresponding gradient, described metal core rod 2 is supportting described elastic overcoat 1, and described elastic overcoat 1 appearance and size is remained unchanged.So just can guarantee the louvre shape and size precision of pouring into a mould out.
For ease of mounting or dismounting, the present invention also is provided with handle 3, and described handle 3 is installed by screwed hole 2b and the handle screw 4 on described metal core rod 2 tops.
