14 li of the nozzle body engagement grooves of described flow distribution plate 10 bottom surfaces are fixed in described nozzle body 21 upper end by nozzle self-centering apparatus 40, described nozzle body 21 lower end is inserted and is arranged in the described nozzle installing hole 1a in described cover half 1.
As shown in Figure 2, described nozzle self-centering apparatus 40 comprises from top to bottom arranged in sequence in attaching parts 41, guard ring 43 and the guide ring parts 46 in the outside of described nozzle body 21.The inwall of the through hole of described attaching parts 41 is provided with attaching parts threaded portion 41a, and the nozzle body top threaded portion 21a of described nozzle body 21 upper end is threaded.Described guard ring 43 inside, upper end are provided with the attaching parts accepting groove 43b that accommodates described attaching parts 41, and the lateral surface of described guard ring 43 is provided with guard ring in conjunction with threaded portion 43a, are connected with described nozzle body engagement groove 14 inner threads.When the guard ring of described guard ring 43 screws completely in conjunction with threaded portion 43a and described nozzle body engagement groove 14 inwalls, the attaching parts accepting groove bottom surface 43c of described attaching parts accepting groove 43b with accommodate described attaching parts 41 lower surface sliding-contacts within it, make described attaching parts 41 and described nozzle body 21 can be from described nozzle body engagement groove 14 separated and with described flow distribution plate 10 without relative motion.
Inner side, described guard ring 43 bottom surface is provided with one section of taper shape falling in inward along central axis direction the 1st centre pilot face 43d, described the 1st centre pilot face 43d and conical the 2nd centre pilot face 46b that is located on described guide ring parts 46 and more and more restrain along central axis direction from top to bottom match, by the cooperation between the 1st centre pilot face 43d and the 2nd centre pilot face 46b by the center-aligned of described guide ring parts 46 in described guard ring 43 center, thereby alignd with described resin channels 22 exit in described nozzle body 21 center.
The inwall of the central through hole of described guide ring parts 46 is provided with guide ring parts threaded portion 46a, is threaded with the nozzle body lower thread 21b of portion of described nozzle body 21.When described guide ring parts 46 rotate clockwise or counterclockwise by along described nozzle body 21 axially approach or away from described guard ring 43.Described guide ring parts 46 lower end lateral surface is provided with center seating surface 46d, and described center seating surface 46d inserts described nozzle installing hole 1a and coordinates with nozzle installing hole entrance inwall 1b, keeps described spray nozzle device 20 center constant.
In addition, described guide ring parts 46 circumferencial directions are provided with a plurality of self-centerings confirmation through hole 46c.Described guide ring parts 46 are moved to described guard ring 43, described the 2nd centre pilot face 46b is contacted with described the 1st centre pilot face 43d, under this state, by inserted described self-centering confirmation by lower end, with the insertion depth of the needle of through hole 46c, confirm centering state.
Self-centering process of the present invention: first assemble described nozzle self-centering apparatus 40 on described nozzle body 21, in the outside of described nozzle body 21, described guide ring parts 46, guard ring 43 and attaching parts 41 are put in order, the guide ring parts threaded portion 46a of described guide ring parts 46 is connected with the nozzle body lower thread 21b of portion of described nozzle body 21 by screw thread, then by described nozzle body top threaded portion 21a, attaching parts 41 is fixed on to described nozzle body 21 upper end.
The described nozzle body 21 that nozzle self-centering apparatus 40 is housed is inserted in nozzle body engagement groove 14 and the outside of described guard ring 43 and described nozzle body engagement groove 14 inwalls are threaded connection, and make described attaching parts accepting groove 43b bottom surface 43c produce supporting role to described attaching parts 41 bottom surface, thereby the nozzle body 21 that described attaching parts 41 are now housed not can with 14 li of separated described flow distribution plate 10 bottoms of being fixed on of described nozzle body engagement groove.
Rotate described guide ring parts 46 until described the 2nd centre pilot face 46b and described the 1st centre pilot face 43d coordinate, thereby make the center-aligned described nozzle body 21 center of described guide ring parts 46 center and described guard ring 43 and the center, resin channels 22 exit of described flow distribution plate 10 keep alignment.
Then the assembly that the spray nozzle device 20 having been alignd in nozzle body 21 center and described resin channels 22 centers, exit and flow distribution plate 10 form is installed in the nozzle installing hole 1a of described cover half 1.
Then described guide ring parts 46 opposite spins that contact with described guard ring 43, described guide ring parts 46 are moved to the direction away from described guard ring 43, described guide ring parts 46 center seating surface 46d contacts cooperation with the nozzle installing hole entrance inwall 1b of described nozzle installing hole 1a, and described nozzle body 21 is installed in described cover half 1 with self-centering state.
During injection moulding, there is horizontal thermal expansion distortion (installation direction of relative spray nozzle device horizontal) in the heat effect meeting that described flow distribution plate 10 is subject to heating wire rod 13 and high-temperature fusion resin, but dissolved by described guard ring 43 transverse movements, distortion can not passed to described nozzle body 21, thereby described nozzle body 21 center remains unchanged.
Described nozzle self-centering apparatus 40 absorbs the horizontal thermal expansion of described flow distribution plate 10 and maintains the constant process in described nozzle body 21 center as shown in Figures 4 and 5: the centering of Fig. 4 embodiment mono-completes the profile that rear nozzle device and flow distribution plate are arranged on mould and maintain aligned condition.Fig. 5 is that the nozzle self-centering apparatus absorption flow distribution plate thermal expansion distortion rear nozzle main body of embodiment mono-maintains the constant profile in center.
As shown in Figures 4 and 5, while there is horizontal thermal expansion distortion in described flow distribution plate 10, the described guard ring 43 being fixedly connected with described flow distribution plate 10 is also followed transverse shifting, glade plane space C between the inwall of described attaching parts accepting groove 43b and the lateral surface of described attaching parts 41 absorbs the transverse shifting that is out of shape the described guard ring 43 causing because of the thermal expansion of described flow distribution plate 10, the distortion that thermal expansion causes so can not affect described attaching parts 41 position, thereby the nozzle body 21 that described attaching parts 41 are housed can not be subject to the impact of thermal expansion distortion yet, maintains centering state.
