AI Technical Summary

Technical Problem

When hot pressing the glass micro-nano components with high aspect ratio, it is difficult for the glass material to flow evenly into the deep groove, resulting in incomplete filling or voids, affecting the quality of the finished product, and high pressure can easily lead to adhesion and jamming between the mold and the glass, and inconvenient demolding.

Method used

A hot press release device is provided, including a locking assembly, a first half set and a second half set. Through the locking and unlocking state of the locking assembly, effective positioning and release of the upper mold, lower mold and glass blank are achieved, and forcibly release the mold in the vertical direction is avoided.

Benefits of technology

It improves the mold release convenience of glass blanks, avoids damage to the hot-pressed glass blanks during the mold release process, and improves the quality and efficiency of hot-pressing.

Abstract

The invention belongs to the field of glass hot-pressing technical equipment, and particularly relates to a hot-pressing demolding device, a hot-pressing mold and a hot-pressing method. The hot-pressing demolding device comprises a lock catch assembly, a first half sleeve with a first groove and a second half sleeve with a second groove, and the first groove and the second groove jointly form a positioning hole. The lock catch assembly has a locking state and an unlocking state, and when the lock catch assembly is in the locking state, the lock catch assembly is connected with the first half sleeve and the second half sleeve and limits relative movement of the first half sleeve and the second half sleeve in the first direction; and when the lock catch assembly is in the unlocking state, movement limitation on the first half sleeve and the second half sleeve is relieved. The upper mold, the lower mold and the glass blank can be prevented from being forcibly pulled out of the positioning hole in the vertical direction, and the demolding convenience of the glass blank is improved.
