Sliding block provided with inclined top and used for demolding

Abstract

The invention relates to a sliding block provided with a inclined top and used for demolding, and belongs to the technical field of automobile part machining. The sliding block provided with the inclined top and used for demolding comprises a sliding block body, an inclined guide column, a pressing block and the inclined top inner core. According to the sliding block provided with the inclined topand used for demolding, the inclined guide column, the pressing block, the sliding block body and the inclined top inner core are arranged, the displacement of the inclined guide column drives the sliding back body to move backwards to avoid the contact damage of a longitudinal undercut structure of a product. When the sliding block body moves backward, the sliding block body drive the inclined top inner core to move laterally to avoid the contact damage of a lateral undercut structure of the product. The product with the undercut structures is directly subjected to mold opening in one direction, the mold opening process is reduced, the production efficiency is improved, and broad application prospects are achieved.

Description

technical field [0001] The invention relates to a slide block for demoulding with an inclined top, which belongs to the technical field of auto parts processing. Background technique [0002] At present, in automobile manufacturers, most of the automotive parts such as lamps are produced by injection molding. See attached Figure 1-3 ) will have horizontal and vertical undercut structures on the surface, which makes it impossible to directly open the mold in one direction in the vertical direction when the upper and lower molds are opened. If the mold is forced to open in one direction, the contact damage between the mold and the product undercut structure will occur To deal with this situation, the traditional method is to slowly push the product in the direction opposite to the barb through vertical and horizontal thimbles to avoid contact damage before opening the mold, but this will undoubtedly increase the mold opening process.
