Problems solved by technology

[0002] Traditional injection molding products have a common feature, that is, the product after demoulding together with the head, and then separated by manual trimming, the disadvantage is that it is labor-intensive and time-consuming, and the efficiency is low. The cost of the mold is high, and it is generally suitable for large-scale production and perennial production. It is not suitable for injection molding products with low output and multi-point gates, and the appearance of the separated products is not as good as that of manual trimming.

Abstract

The invention discloses a device for breaking and separating a pull piece and a material bone, which is used for separating the pull piece from an injection molded part. The injection molded part includes a material bone and pull pieces distributed on both sides of the material bone connected by a material handle, which includes a frame And the first limit groove, the second limit groove, the pull-off separation mechanism and the press-down mechanism arranged on the frame; the first limit groove and the second limit groove are used for inserting the pull piece and connecting with the pull piece The material handle; the pull-off separation mechanism is used to separate the first limiting groove and the second limiting groove from each other along the direction perpendicular to the material bone; the pressing mechanism is used to separate the first limiting groove and the second limiting groove Press the material bone at the same time, so that the material bone cannot be displaced relative to the frame; After separation, the technical solution of flipping to complete automatic blanking is realized. The separation efficiency of this solution is higher than that of manual trimming, and the separation quality is more guaranteed than manual trimming.

Description

technical field [0001] The invention relates to a device for breaking and separating an injection molded product and a material bone, in particular to a device for breaking and separating a pull piece and a material bone. Background technique [0002] Traditional injection molding products have a common feature, that is, the product after demoulding together with the head, and then separated by manual trimming, the disadvantage is that it is labor-intensive and time-consuming, and the efficiency is low. The cost of the mold is high, and it is generally suitable for large-scale production and perennial production. It is not suitable for injection molding products with low output and multi-point gates, and the appearance of the separated products is not as good as manual trimming. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned defects or problems in the background technology, and provide a breaking and separating de...
