Spot adhesive feeding cold runner injection mold with twin stripper plates

Abstract

The invention provides a spot adhesive feeding cold runner injection mold with twin stripper plates. The spot adhesive feeding cold runner injection mold comprises an upper mold body, a lower mold body, an upper fixing plate for fixing the upper mold body and a lower fixing plate for fixing the lower mold body. A stripper device for being separated from a waste end is arranged between the upper mold body and the upper fixing plate. The stripper device is movably connected with the upper mold body through a connecting piece. The upper mold body and the upper fixing plate can be switched between the separated state and the combined state. When the upper mold body and the upper fixing plate are combined, the stripper device is clamped between the upper mold body and the upper fixing plate and connected with the waste end on one side of the upper mold body; when the upper mold body and the upper fixing plate are separated, the upper mold body moves towards one side of the lower mold body relative to the stripper device and drives the stripper device to draw the waste end on one side of the upper mold body out of the upper mold body through the connecting piece while moving. The spot adhesive feeding cold runner injection mold is reasonable in structural design; the problem that waste does not disengage thoroughly can be solved; the appearance of produced products can be made smooth, and no marks of adhesive feeding spots exist.

Description

technical field [0001] The invention relates to the technical field of injection mold mechanisms, in particular to a double stripper plate cold runner point-feed injection mold. Background technique [0002] As people's requirements for the appearance of various daily and industrial products are increasing, as the requirements for the appearance of various plastic products are increasing, their appearance conditions naturally become an important factor for people to evaluate the appearance of products. Among them, the gate position of the product, gate traces, welding Lines have become one of the elements that affect people's acceptance of products. [0003] The mold is an indispensable and important tool in injection molding. Injection molding is to inject hot-melt plastic material into the closed cavity with the required shape in the mold at high speed. After the plastic material is cooled and solidified, the mold is opened to push the solidified plastic product into the m...

Problems solved by technology

[0004] However, the existing point-in-glue cold runner injection mold adopts the traditional point-in-glue method. After the injection molding is opened, the waste head cannot fall off by itself, and the waste head must be removed manually or by a robot, which is prone to fall off and is not clean. When the upper and lower molds of the mold are closed, the material head is pressed, and the production cannot be performed after the mold is pressed, and the mold needs to be removed from the machine, which brings great difficulties to normal production.

At the same time, it will cause the injection point to be in the center of the outer surface of the product, leaving more or less injection marks on the appearance of the product, which directly affects the aesthetics of the product

[0005] Therefore, the applicant is committed to providing a double stripper plate cold runner point injection mold, which has a reasonable structural design, can solve the problem of waste falling off and falling off, and can make the produced product smooth in appearance, without further progress.
