In the machinery industry, the installation and disassembly of mechanical parts always run through the operation of various equipment, tooling, and fixtures. In the die-casting industry, there are many inserts in die-casting molds, and die-casting molds have to face high temperature and high pressure. , and have to withstand sudden cooling and spraying to ensure the stability of product quality. The life of the die-casting mold will also cause thermal cracking of expensive steel due to the impact of supercooling and overheating. Different materials are subject to repeated temperature changes. Next, due to thermal expansion and other reasons, why keep a good seal? The matching gap between the die-casting mold parts must be extreme and precise, so as to avoid gaps in the production process that lead to the leakage of cooling water for the die-casting mold, thus making the die-casting mold invalid. Product fails.

Taking the die-casting mold of a cold-chamber horizontal die-casting machine as an example, the die-casting insert part is subjected to the working environment under the above-mentioned conditions, including high temperature, high pressure, and cooling water.

In addition, the existing die-casting mold inserts are disassembled by manpower, erect and fix the die-casting mold, and use a hanging tool to lift the knock bar. Under the action of manpower and the inertia of the knock stick swing, the gate insert is hit , so that it is separated from the die-casting die of the die-casting die body, but there is a risk of damaging the components of the die-casting die during the knocking process.
