Jewelry precision punching plastic burning needle mold

Abstract

The invention discloses a jewelry precision punching plastic burning needle mold. The mold comprises a bottom plate and a first fixed mold, wherein a matching column is fixed to the outer edge of thebottom plate; an assembly hole is formed in the matching column; a bottom panel is arranged on the upper surface of the bottom plate; a stainless steel punching needle is arranged on the upper surfaceof the bottom panel; a second fixed mold is mounted above the first fixed mold; the first fixed mold is located above the bottom plate; a third fixed mold is arranged above the second fixed mold; andlugs are fixed to the outer edges of the first fixed mold, the second fixed mold and the third fixed mold. The jewelry precision punching plastic burning needle mold is formed in a manner that the three fixed molds are superposed together, matched with the circular bottom plate and locked by three fixing screws; a fixed mold plate is formed by one-time injection molding of a precision plastic mold and is made of PC and glass fiber plastic raw materials with the temperature resistance and the high stability; and the circular bottom plate is also formed by one-time injection molding of the precision plastic mold and is made of the same materials the same as that of the fixed mold plate.

Description

technical field [0001] The invention relates to the technical field of jewelry processing molds, in particular to a jewelry precision punching plastic burning needle mold.

AI Technical Summary

Problems solved by technology

[0003] The object of the present invention is to provide a jewelry precision punching plastic needle burning mold to solve the existing jewelry punching and burning molds on the market proposed in the above-mentioned background technology. It is composed of three fixed molds stacked together and a square bottom plate. The fixed mold is a thermosetting material plus an iron plate. It is formed by a simple heating mold. The molding cycle is about 15 minutes each. The processing technology is simple and rough, so the precision is not enough (about 30 wires), and there are problems in the subsequent ultrasonic drilling. The template is not durable, the precision is not enough, the defective products are high, and the scrap rate is high.
