AI Technical Summary

Technical Problem

In the existing joint chain processing methods, the welding of the connecting ring is prone to break, the overall strength of the chain is poor, and the smoothness and aesthetics are poor.

Method used

The joint-chain wax embryo alloy embryo mold is used to process the primary wax embryo, connecting ring wax embryo and chain wax embryo respectively through the design of upper mold and lower mold, and form a joint wax embryo, eliminating welding interfaces and improving structural strength and aesthetics.

Benefits of technology

It significantly improves the structural strength of the chain, reduces the risk of breaking, ensures higher smoothness and aesthetics, improves the overall quality of the joint chain, reduces labor costs, and improves the production efficiency and product quality of 5D gold bracelets.

Abstract

The utility model provides a one-piece chain wax blank alloy blank mould which comprises an upper mould, a lower mould and a mould core rod, the upper mould is provided with a first primary blank groove, a first connecting ring groove and a first chain ring groove, the lower mould is provided with a second primary blank groove, a second connecting ring groove and a second chain ring groove, and the first primary blank groove and the second primary blank groove define a primary blank cavity. The first connecting ring groove and the second connecting ring groove define a connecting ring cavity, the core rod extends into the primary blank cavity, the primary blank cavity is used for injecting a first wax material to process a primary wax blank, the core rod is used for processing a hollow cavity of the primary wax blank, and the connecting ring cavity is used for placing the primary wax blank and injecting a second wax material on the outer side of the primary wax blank to process a connecting ring wax blank; the first chain ring groove, the second chain ring groove and the hollow cavity of the primary wax blank form a chain ring cavity, and the chain ring cavity is used for injecting a second wax material to process a chain ring wax blank. In the embodiment of the invention, the conjoined chain is formed at one time in a conjoined form, so that the structural strength of the chain is remarkably improved.
