Abstract

The invention discloses a secondary mold stripping mechanism for an automotive interior trim injection mold. According to the secondary mold stripping mechanism for the automobile interior trim injection mold, the one-time mold stripping and two-time material ejecting action is adopted to achieve mold stripping function, first ejector rods and second ejector rods act upwards together during firstmold stripping, and then the second ejector rods act upwards during second mold stripping, so that an automotive interior trim is completely separated from the first ejector rods, and therefore, the structure is simple and reliable, and protrusions can be prevented against tearing.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to a secondary demoulding mechanism for injection molds of automotive interior parts. Background technique [0002] At present, there is an automobile interior part, including the interior part, which is provided with a protrusion on the bottom surface of the interior part. The current problem is that when the mold is opened, the conventional ejector pin will be used for demoulding, which will cause the raised ribs to be wrapped on the ejector pin, which makes it difficult to pick up the parts with the robot, and cannot achieve the goal of fully automatic and unmanned operation. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a kind of automotive interior parts that realizes demoulding by one demoulding and two ejecting actions, and has a simple structure and reliability, realizes picking up parts by manipulators...
