Background technology
Multi-gear plastic product, as automobile door lock driving member, owing to having, multiple gear arranged in co-axial alignment are integral, are strict with coaxial precision.Therefore in the time carrying out Design of Dies, not only need designing mould to obtain the given shape of multi-gear product, but also will take into full account the possibility in technical process, coaxial precision being impacted.Prior art injection moulding forms multi-gear plastic product, generally to adopt single cast gate injecting glue, can simplify the design of mould structure although adopt the method, but in actual production, because monolateral injection pressure is larger, easily cause product to have the difference on obvious shape thickness in cast gate one side with away from cast gate one side, and then cause the coaxial precise decreasing of multi-gear product, substandard product rate raises.And adopting symmetrical 2 injecting glues, 2 institute's injecting glues, in conjunction with slower, easily produce composition surface, functional poor, the easy fracture of the follow-up use of product.And mold cools down is also a large problem for the mould of the very high concentricity of this generic request and circularity.
Summary of the invention
To the present invention seeks in order solving the problems of the technologies described above, and even, the cooling multi-gear fast of a kind of injection moulding injection forming mold to be provided.
In order to achieve the above object, technical solution of the present invention is as follows: a kind of multi-gear injection mold, comprise dynamic model and cover half, in described cover half, be provided with a plurality of die cavities, 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 that is communicated to mould outside; In described dynamic model, be provided with the core corresponding with described die cavity, each described core is provided with the annular cooling water pipeline that is communicated to mould outside around.
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 be arranged on described import and outlet between pipe a plurality of extending longitudinally, the inside of described pipe extending longitudinally is installed with dividing plate, cooling water in described pipe extending longitudinally along described dividing plate two side flow; Described a plurality of pipes extending longitudinally that axis is set is parallel with the axis of described shunt conduit, and described a plurality of circumference of cannon bone extending longitudinally is located at described shunt conduit around.
Preferably, on described cover half, be provided with annular recess, with the annular projection of corresponding setting on the described dynamic model location of matching.
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.
Beneficial effect of the present invention is mainly reflected in:
(1) adopt 3 injecting glues, make the product die cavity internal pressure of die cavity and core composition more even;
(2) carry out when injecting glue coolingly in conjunction with the annular water route cooling water channel matching with outer peripheral gear shape, avoided the coaxial precise decreasing of multi-gear product, improved production efficiency;
(3) adopt fountain type cooling water pipeline, coolant flow channel well in cooling die cavity.

Detailed description of the invention
Below in conjunction with accompanying drawing, the technical scheme in the embodiment of the present invention is carried out to clear, complete description, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiment.
As shown in Figures 1 to 5, the present invention has disclosed a kind of multi-gear injection mold, comprises dynamic model 1 and cover half 2.In described cover half 2, be provided with a plurality of die cavities 22, each described die cavity 22 bottom surfaces are 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 that is communicated to mould outside; In described dynamic model 1, be provided with the core 12 corresponding with described die cavity 22, each described core 12 is provided with the annular cooling water pipeline 13 that is communicated to mould outside around.
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 feature of the present invention is not arrange die, thus be easy at the outer sheathed annular cooling water pipeline 13 of described core 12, cooling core 12 so 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 be arranged on described import 273 and export the pipe 271 a plurality of extending longitudinally between 274, the inside of described pipe extending longitudinally 271 is installed with dividing plate 272, and cooling water is interior along 272 liang of side flow of described dividing plate at described pipe 271 extending longitudinally; Described a plurality of pipes 271 extending longitudinally that axis is set is parallel with the axis of described shunt conduit 24, 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, coolant flow channel well in cooling die cavity.
Preferably, on described cover half 2, be provided with annular recess 26, with the annular projection 14 of corresponding setting on described dynamic model 1 location of matching.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 die cavity internal pressure of die cavity and core composition more even, thereby can ensure concentricity and circularity between stability and the gear of product size, obtain high-quality product..
When apparatus of the present invention are used, locate matched moulds by 14 of the annular projections on dynamic model 1 and cover half 2 and annular recess 26, then open injection system, to injecting glue in the product die cavity of die cavity and core composition, in the process of injecting glue, cooling water in annular cooling water pipeline 13 is flow circuit around die cavity constantly, 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 present invention is because the bottom surface from product adopts 3 injecting glues, make the product die cavity internal pressure of die cavity and core composition more even, when injecting glue, carry out cooling in conjunction with the annular cooling water pipeline, the fountain type cooling water pipeline that match with outer peripheral gear shape, avoid the coaxial precise decreasing of multi-gear product, improve production efficiency, strengthen product utility function, not easy fracture.
Based on embodiments of the invention, those of ordinary skill in the art, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
