In order to achieve the above object, technical solutions of the utility model are as follows: a kind of multi-gear injection mold, comprise dynamic model and cover half, a plurality of die cavity is provided with in described cover half, each described die cavity bottom surface is provided with the cast gate of three injecting glues, three cast gates of each die cavity are communicated to injecting glue main pipeline by length, shunt conduit that caliber is identical, and then connection glue injection system; The surrounding of described die cavity is provided with the fountain type cooling water pipeline being communicated to mold exterior; Be provided with the core corresponding with described die cavity in described dynamic model, around each described core, be provided with the annular cooling water pipeline being communicated to mold exterior.
Preferably, described annular cooling water pipeline comprises import and outlet, and is arranged on the ring part between described import and outlet, and the diameter of described ring part is greater than the diameter of described core, and described ring part is surrounded on outside described core.
Preferably, described fountain type cooling water pipeline comprises described import and outlet, and the pipe a plurality of extending longitudinally be arranged between described import and outlet, the inside of described pipe extending longitudinally is installed with dividing plate, and cooling water flows along described dividing plate both sides in described pipe extending longitudinally; The axis being parallel that axis and described shunt conduit are set of described a plurality of pipe extending longitudinally, and described a plurality of circumference of cannon bone extending longitudinally is located at around described shunt conduit.
Preferably, described cover half is provided with annular recess, the annular projection of setting corresponding with on described dynamic model matches and locates.
Preferably, three cast gates on each described die cavity connect into equilateral triangle, and the center of described equilateral triangle overlaps with multi-gear product axis.
The beneficial effects of the utility model are mainly reflected in:
(1) adopt 3 injecting glues, make the product mould cavity pressure of die cavity and core composition more even;
(2) combine the annular water channel cooling water channel closed with outer peripheral gear matching form during injecting glue to cool, avoid the coaxial precise decreasing of multi-gear product, improve production efficiency;
(3) fountain type cooling water pipeline is adopted, can coolant flow channel well while cooling die cavity.

Detailed description of the invention
Carry out clear, complete description below in conjunction with accompanying drawing by the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.
As shown in Figures 1 to 5, the utility model discloses a kind of multi-gear injection mold, comprises dynamic model 1 and cover half 2.A plurality of die cavity 22 is provided with in described cover half 2, each described die cavity 22 bottom surface is provided with the cast gate 23 of three injecting glues, three cast gates 23 of each die cavity 22 are communicated to injecting glue main pipeline 25 by length, shunt conduit 24 that caliber is identical, and then connection glue injection system; The surrounding of described die cavity 22 is provided with the fountain type cooling water pipeline being communicated to mold exterior; Be provided with the core 12 corresponding with described die cavity 22 in described dynamic model 1, around each described core 12, be provided with the annular cooling water pipeline 13 being communicated to mold exterior.
Concrete, as shown in Figure 3, described annular cooling water pipeline 13 comprises import 132 and outlet 133, and is arranged on the ring part 131 between described import 132 and outlet 133, the diameter of described ring part 131 is greater than the diameter of described core 12, and described ring part 131 is surrounded on outside described core 12.Because one of the utility model feature is not arrange die, so be then easy at the outer sheathed annular cooling water pipeline 13 of described core 12, like this can cooling core 12 more fully, cooling effect neither prior art can compare.
Concrete, as shown in Figure 4, described fountain type cooling water pipeline 27 comprises described import 273 and outlet 274, and the pipe 271 a plurality of extending longitudinally be arranged between described import 273 and outlet 274, the inside of described pipe extending longitudinally 271 is installed with dividing plate 272, and cooling water flows along described dividing plate 272 both sides in described pipe 271 extending longitudinally; The axis being parallel that axis and described shunt conduit 24 are set of described a plurality of pipe 271 extending longitudinally, and described a plurality of pipe 271 extending longitudinally is located in described shunt conduit 24 around.Like this, adopt fountain type cooling water pipeline, can coolant flow channel well while cooling die cavity.
Preferably, described cover half 2 is provided with annular recess 26, matches with the annular projection 14 of corresponding setting on described dynamic model 1 and locate.Three cast gates 23 on each described die cavity 22 connect into equilateral triangle, the center of described equilateral triangle overlaps with multi-gear product axis, make the product mould cavity pressure of die cavity and core composition more even, thus the concentricity between the stability of product size and gear and circularity can be ensured, obtain high-quality product..
When the utility model device uses, matched moulds is located by the annular projection on dynamic model 1 and cover half 2 14 and annular recess 26, then injection system is opened, injecting glue in the product die cavity that die cavity and core are formed, in the process of injecting glue, cooling water in annular cooling water pipeline 13, constantly in the circulation of die cavity ambient dynamic, takes away heat for cooling; Same, described fountain type cooling water pipeline 27 is also in cooling die cavity 22 and cooling shunt conduit 24.
Because the utility model is owing to adopting 3 injecting glues from the bottom surface of product, make the product mould cavity pressure of die cavity and core composition more even, the annular cooling water pipeline that during injecting glue, combination and outer peripheral gear matching form close, fountain type cooling water pipeline cool, avoid the coaxial precise decreasing of multi-gear product, improve production efficiency, strengthen product utility function, not easy fracture.
Based on embodiment of the present utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
