Description

Technical Field

[0001] The utility model relates to a forming mold, in particular to an inclined ejection mechanism in a slide block of the forming mold. Background Art

[0002] With the rapid development of the times and the improvement of science and technology, the types of automotive interior product structures are changing with each passing day, becoming more diversified, structured, and more complex. This also promotes the continuous innovation of mold structures, and the corresponding mold structures are becoming more and more complex. The quality of products is directly linked to the rationality of mold structures.

[0003] The conventional slider core-pulling structure can only solve the problem of simple unobstructed product undercut structures. When the product has a horizontal undercut structure less than 90°, multiple sets of molds are conventionally used for batch molding, which cannot achieve the requirement of one-time molding of the undercut structure.
