Abstract
The utility model relates to an anti-drawing spacer, in particular to an anti-drawing spacer for a mold, which comprises a cooling sprue bush, wherein a gun nozzle is arranged in the middle of the upper part of the cooling sprue bush, and fitting holes are respectively arranged on the edges of the two ends of the upper part of the cooling sprue bush; and the anti-drawing spacer is arranged at the upper part of the cooling sprue bush and penetrates through the gun nozzle. The anti-drawing space for the mold has a simple structure, the manufacturing cost is reduced, and the efficiency is improved.
Description
Technical field
The utility model patent relates to a kind of anti-wire drawing partition, relates in particular to the anti-wire drawing partition that is used for mould.
Background technology
Present traditional cooling sprue bush all is a monoblock type, in process of injection molding, be cooled owing to molten plastic end, big gun mouth place, thereby cause runner interruption-forming wire drawing after the die sinking, elongated being attached on the runner and not of wire drawing solidified fully, be set in product surface with descending slowly and lightly after the product taking-up, the product appearance quality is impacted.
Summary of the invention
The utility model mainly is to solve the deficiencies in the prior art, and a kind of heat of effectively leading away big gun mouth place molten plastic is provided, and fundamentally stops wire drawing and forms, and has solved the anti-wire drawing partition that is used for mould of wire drawing problem in the actual production.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of anti-wire drawing partition that is used for mould, comprise the cooling sprue bush, the interposition on described cooling sprue bush top is provided with the big gun mouth, the edges at two ends on described cooling sprue bush top is respectively equipped with the close-fitting hole, described cooling sprue bush top is provided with anti-wire drawing partition, and described anti-wire drawing partition passes the big gun mouth.Fluting increases anti-wire drawing partition on the cooling sprue bush, and the heat of leading away big gun mouth place molten plastic of effect is fundamentally stopped wire drawing and formed, and has solved wire drawing problem in the actual production; The centre of anti-wire drawing partition is provided with arc gap, and described arc gap and big gun mouth are complementary.
As preferably, described anti-wire drawing partition is located between the close-fitting hole, and the intermediate point line in close-fitting hole and anti-wire drawing partition are perpendicular, and described anti-wire drawing partition extends to the edge on cooling sprue bush top.
As preferably, described big gun mouth is bowl-shape, and described close-fitting hole is a counterbore.
Therefore, the anti-wire drawing partition that is used for mould of the present utility model, simple in structure, reduce cost of manufacture, raise the efficiency.
