Slide block demolding structure for inner side undercut

Abstract

The invention discloses a slide block demolding structure for an inner side undercut. The slide block demolding structure comprises a slide insert which can be inserted into the inner side undercut ofa product; the slide insert comprises a movable slide main body, a rotary connection block is movably connected to the slide block main body, when the movable slide main body moves, the rotary connection block can be driven to move, the moving path of the slide block main body is perpendicular to the moving path of the rotary connection block, and the rotary connection block is movably connectedwith the slide block insert; when the rotary connection block moves, the slide block insert can be driven to move, the moving path of the rotary connection block is perpendicular to the moving path ofthe slide block insert, the moving paths of the slide block insert and the slide block main body are parallel, and the moving directions of the slide block insert and the slide block main body are opposite. The slide block demolding structure for the inner side undercut adopts the split parts and the linkage action mode, the slide block structure is transformed to be more convenient to machine and assemble, and moving is more stable and reliable.

Description

technical field [0001] The invention belongs to the field of mold processing, and in particular relates to a sliding block ejection structure with an inner undercut on a molded product. Background technique [0002] In order to meet the ever-changing needs of customers, the product structure developed by manufacturers is generally becoming more and more complex. For mold forming, the most difficult solution is the release of undercuts, especially when there are undercuts on the inside of the product. There are some solutions on the market at present, but they generally cannot solve the problems that the molding inserts of the slider are easily deformed and the overall slider is difficult to assemble. [0003] For example, the Chinese invention patent application with the publication number CN103481465A relates to a slider ejection structure with an inner undercut. Although it can initially solve the mold ejection problem of the inner undercut, the following problems still e...
