AI Technical Summary

Technical Problem

During the foaming process, the collision between the foaming material and the embedded material causes the hook fastener to curl, affecting the fastening function and resulting in production defects and material waste.

Method used

Vertical walls are provided on the protrusions on the bottom surface of the mold to prevent the foam material from colliding with the embedded material. The vertical walls extend along the protruding direction of the protrusions and beyond the top to prevent the material from flowing into the embedded material.

Benefits of technology

It effectively prevents undesirable flow of foamed material into the embedded material, reduces production defects, and improves the quality and material utilization of foamed molded products.

Abstract

The present invention provides a molding die which avoids the undesirable flow of a foaming raw material into an insert material which is integrally molded with a foamed molded product, thereby contributing to the production of a sound foamed molded product. A convex portion is formed on a die bottom surface which defines a cavity of the molding die, and a vertical wall which extends along a protruding direction of the convex portion and exceeds a top portion of the convex portion.
