AI Technical Summary

Technical Problem

Existing curved surface fixtures are difficult to manufacture, and flat shoe mold fixtures are difficult to bend into 3D curved surface fixtures, which makes it difficult for cylindrical pattern machines to sew three-dimensional fabrics.

Method used

Design a thermoforming mechanism for a 3D shoe mold fixture. The mechanism uses a thermoforming upper mold and a thermoforming lower mold to bend and shape the planar shoe mold fixture through heating and pressing. The mechanism includes a frame, top plate, bottom plate, pressing drive device, adapter seat, thermoforming upper mold and thermoforming lower mold. Electric heating rods and heat insulation pads are used to improve thermal efficiency and positioning accuracy.

Benefits of technology

It achieves efficient bending and forming of planar shoe mold fixtures, enabling the production of 3D curved shoe mold fixtures and improving the ability of cylindrical pattern machines to sew three-dimensional fabrics.

Abstract

The utility model relates to hot press forming mechanism technical field of computer pattern machine shoe mould clamp, specifically relates to a kind of hot press forming mechanism of 3D shoe mould clamp, using rack, top plate, bottom plate, press-down driving device, adapter seat, hot press upper die and hot press lower die, the shape of hot press upper die is semicylinder shape and curved surface is towards hot press lower die, hot press lower die is provided with semicylindrical slot, and hot press upper die and hot press lower die are matched for further hot-press bending shaping to heat-softened plane shoe mould clamp. When actually processing, plane shoe mould clamp is transferred to the hot press forming mechanism after being heated by means of hot drying and being heat-softened in advance, plane shoe mould clamp is placed on the semicylindrical slot of hot press lower die, and hot press upper die is driven to press down by press-down driving device, and hot press upper die and hot press lower die cooperate to hot-press plane shoe mould clamp, so that plane shoe mould clamp is further bent and shaped, so that 3D cambered surface shoe mould clamp is obtained after subsequent cooling.
