Abstract

The utility model discloses a kind of carbon brush holder mould structures of secondary injection molding, including being once molded and quadric injection mould, the less plastic cement filling of the inserts difficult with positioning support not easy to place is rolled into a simple global feature for the first time, this global feature is put into filling molding product in mold for the second time.The bad placement of inserts in product and locating bias can be effectively solved, improving product quality reduces fraction defective, while also being provided a convenient for the post-processing of product.

Description

A kind of carbon brush holder mould structure of secondary injection molding
Technical field
The utility model is related to the injection structures that a kind of auxiliary simplifies product manufacture, belong to product design and mold system Make technical field, the carbon brush holder mould structure of specifically a kind of secondary injection molding.
Background technology
Mold be in industrial production to be molded, be blow molded, squeeze out, the side such as die casting or forging forming, smelting, punching press, stretching Method obtains the various moulds and tool of required product.It is especially more with inserts in product at present, the design meeting of product structure therewith Corresponding complicated many, because band inserts stability is good, service life is grown by a large amount of demand, but the mould structure of injecting products does not have Have what improvement, when inserts need to place more, manual operation can waste the plenty of time, and be susceptible to leakage put, misplaced meeting, It causes bad products to occur and is not easy to check that defective products is caused to flow out, society and company can be given to bring massive losses, spy is product It is divided into injection molding twice, is molded inserts, second of injection molding product for the first time, that is, ensure that the quality of product again can be greatly Reduction production efficiency, fraction defective, simplify production technology, reduce cost etc..
Invention content
In view of the above-mentioned problems of the prior art, the utility model provides a kind of carbon brush frame mould of secondary injection molding The less plastic cement filling of the inserts difficult with positioning support not easy to place is rolled into one simply by structure, the structure for the first time Global feature, this global feature is put into filling molding product in mold by second.Inserts can effectively be solved in product not Good placement and locating bias, improving product quality reduces fraction defective, while also being provided a convenient for the post-processing of product.
To achieve the goals above, the technical solution adopted in the utility model is:A kind of carbon brush holder of secondary injection molding Mould structure, including be once molded and quadric injection mould, it is characterised in that:Primary injection molding includes mold I, mode I, position mold insert I, Positioning pin I, mold cavity I, I intermediate position of mold are equipped with the runner I communicated with mold cavity I, are inlayed equipped with positioning on mold I Part I and positioning pin I and mode I, several inserts I are placed in order on the positioning mold insert I in mold I and positioning pin I, mould Benevolence I adjusts the side for lying in several inserts I, is groove and " V " type locating slot higher than several inserts I among positioning mold insert I; It positions pin I and passes through I location hole of several inserts and the surface higher than several inserts I, the head for positioning pin I is convenient for putting to oblique angle It sets;Plastic cement is injected into mold cavity I by runner I, waits for that a moulding plastic cement is cooled and shaped, last injection molding machine ejection one Secondary moulding.
The quadric injection mould includes mold II, mode II, positions pin II, inserts II, mold cavity II, in mold II Between position be equipped with the runner II that is communicated with mold cavity II, equipped with positioning pin II and mode II, mold cavity II on mold II It is equipped with location hole, the positioning edge being placed on by position of positioning hole in mold II is arranged on mold cavity II in a moulding On needle II, positioning pin II passes through the location hole of several inserts and the surface higher than several inserts, and positioning II head of pin is to tiltedly Angle is convenient for placement;Then plastic cement is injected into mold cavity II by runner II, waits for that secondary injection plastic plastic cement is cooled and shaped, most Injection molding machine ejects second of moulding, that is, the product of final molding afterwards.
Further, the feasibility for ensureing the positioning of first time moulding, placing.
Further, ensure second not change product appearance and performance after being molded.
The utility model has the beneficial effects that:After being molded respectively twice by this, make in product design, increases design knot The feasibility of structure feasibility and mold manufacturing makes product more play due effect, reduces die cost, improves production Efficiency and product quality.
