Detailed description of the invention

For making the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and embodiments, the utility model is described in further details.At this, exemplary embodiment of the present utility model and illustrating for explaining the utility model, but not as to restriction of the present utility model.

Shown in Fig. 1 and Fig. 2, end cap has female thread structure respectively in relative A face and B face.The injection mold of a kind of end cap of the present utility model thus, comprises the corresponding front mould 2 that arranges and rear mold 4, is limited with four rectangular distributions and the die cavity 6(adapted with end cap profile is shown in Figure 5 after this front mould 2 and rear mold 4 matched moulds).

Shown in Fig. 3, Fig. 4, Fig. 6 and Fig. 7, front mould 2 is provided with four front cavitys 8, the profile of profile and end cap A face that each front cavity 8 is positioned at the end of die cavity 6 adapts, and front cavity 8 can rotate centered by its axis, shown in Fig. 8 and Fig. 9, the rotation of this front cavity 8 is can the first rifle screw mandrel 12 of telescopic moving by being provided with in front mould 2, this the first rifle screw mandrel 12 is set with the first rifle silk braid 14, this the first rifle silk braid 14 is set with the first gear 16, this first gear 16 is mutually meshing and front cavity 8 can be driven to rotate with front cavity 8, during die sinking, first rifle screw mandrel 12 can be pulled along with opening of mould, the the first rifle silk braid 14 coordinated with it is made to rotate in the process that first rifle screw mandrel 12 is pulled, the first meshing with it gear 16 is driven to rotate when first rifle silk braid 14 rotates, front cavity 8 meshing is with it driven to rotate when first gear 16 rotates, due to front cavity 8 and the A face threaded engagement of end cap, the A face of end cap just can be made to be separated with front cavity 8 when front cavity 8 is rotated when end cap is fixed, in addition, rear mold 4 is provided with rear cavity 10(see Figure 10 and Figure 11), the profile of profile and end cap B face that this rear cavity 10 is positioned at the end of die cavity 6 adapts, and this rear cavity 10 can rotate centered by its axis, shown in Fig. 4 and Figure 12, the rotation of this rear cavity 10 is can the second rifle screw mandrel 18 of telescopic moving by arranging in rear mold 4, this the second rifle screw mandrel 18 is set with the second rifle silk braid 20, on this second rifle silk braid 20, meshing being connected with rotates throw-out collar 22, rotate throw-out collar 22 be connected with rear cavity 10 and rear cavity 10 can be driven to rotate, when die sinking, second rifle screw mandrel 18 is pulled, the the second rifle silk braid 20 coordinated with it is made to rotate in the process that second rifle screw mandrel 18 is pulled, rotation throw-out collar 22 meshing is with it driven to rotate when second rifle silk braid 20 rotates, rotating when throw-out collar 22 rotates drives rear cavity 10 meshing with it to rotate, due to rear cavity 10 and the B face threaded engagement of end cap, the B face of end cap just can be made to be separated with rear cavity 8 when rear cavity 10 is rotated when end cap is fixed.

Shown in Fig. 8 and Fig. 9, for making structure of the present utility model compact and reasonable more, and guarantee the synchronism that four front cavitys 8 rotate, a first rifle screw mandrel 12 is provided with in front mould 2, and it is set with a first rifle silk braid 14, first rifle silk braid 14 is respectively installed with first gear 16, first gear 16 mutually meshing with adjacent two front cavitys 8 respectively, and the center of four front cavitys 8 of distributed rectangular is provided with a gear 15.This gear 15 guarantees the rotation that four front cavitys 8 are synchronous while driving two other front cavity 8 to rotate.

Shown in Figure 12, for guaranteeing the synchronism of the rotation of multiple rear cavity 10, two the second rifle silk braids 20 are mutually meshing with the rotation throw-out collar 22 in adjacent two rear cavities 10, and the center of four rear cavities 10 is provided with a swing pinion 19, interrelated between each like this rear cavity 10, thus its synchronism rotated can be guaranteed.

Shown in Figure 3, for the generation making the utility model reduce stub bar when cooling forming, thus reach the object of saving injection raw material, the injection molding channel 24 communicated with die cavity 6 is hot flow path, namely injection molding channel 24 connects with the heater (not shown) heated it, like this when having uniform temperature all the time in injection molding channel 24 during cooling forming in die cavity 6 thus preventing this place from cooling and produce unnecessary stub bar.
