In order to guarantee be incubated while can also guarantee injection moulding complete after cooling shaping, the sleeve wall thickness of preferred described muff is 50mm ~ 60mm.
In order to guarantee heat insulation effect further, bottom preferred described injection moulding patrix, equal the height of injection moulding counterdie from the distance bottom muff.
Further preferred described injection moulding counterdie can be enclosed within muff.Accelerate the heat radiation in injection moulding aftershaping stage.
The beneficial effect that the present invention has is:
By the present invention, its structure is simple, when gear injection moulding, under the effect of muff, has certain insulation effect to its injection moulding environment temperature, decreases the hollow phenomenon occurred in the middle of injection moulding gear out, improves the qualification rate of product.The die sinking work after gear injection mo(u)lding is effectively facilitated under the elastic reaction of rubber sleeve, time saving and energy saving.What adopt due to the matched moulds between injection moulding patrix and injection moulding counterdie is electronic mode; therefore the speed of matched moulds and die sinking is fast; production efficiency is high; operate steadily; be applicable to very much the processing of large gear; by driven by motor bolt rotary during use, under coordinate of screw rod with nut, screw rod is moved up or down thus complete die sinking between injection moulding patrix and injection moulding counterdie or matched moulds work.Under the design of cooling chamber, effectively can accelerate the sizing work of product after injection moulding.
