AI Technical Summary
In the existing technology, when the gas is injected at a low speed in the slow stage, it is impossible to fully expel the gas, which leads to a decrease in the temperature of the molten metal, condensation of the metal at the nozzle, and adhesion of the molten metal to the inside of the injection chamber, thus reducing the die casting effect.
The system employs a segmented temperature-controlled integral injection chamber. Through gears, racks, cams, and other structures, the extrusion plate and slide bar move, generating vibrations that break up the bubbles in the molten metal. The system also utilizes air bladders and regulating chambers to create a negative pressure zone that accelerates gas discharge and prevents the molten metal from sticking together.
It effectively breaks up air bubbles inside the molten metal, ensuring rapid gas discharge, maintaining the temperature of the molten metal, and improving the quality and efficiency of die casting.

It is used to store molten metal and to allow the cylindrical injection punch, which is sealed to it, to complete the injection. The injection process is divided into several stages: slow injection stage, molten metal accumulation stage, fast injection stage, and pressurization stage.
[0003] In order to expel the gas in the chamber, the existing technology requires injection at a low speed in the slow stage. However, the gas cannot be fully expelled by the slow speed alone. At the same time, if the time is too long, the temperature of the molten metal will drop, the metal at the nozzle will condense, and the molten metal will stick to the inside of the injection chamber, which will reduce the effect of die casting. Utility Model Content
