Compared with the prior art, the present invention has the following advantageous effects. The present invention is a skillful new configuration implemented in a conventional horizontal cold chamber die casting machine in order to achieve a squeeze casting function, in which a horizontal hot water supply device supplies hot water to a vertical injection device (eg, molten aluminum alloy, molten copper alloy). ), The time required for the four steps of tilting, returning, ascending, and locking the sleeve of the conventional tilting docking injection mechanism is saved, the molten metal transfer speed is increased, the molten metal temperature is less likely to drop, and the initial solidified layer is generated. Reduced, more effective, with vertical injection device
The molten metal is injected and filled into the die-cast cavity of the mold at a predetermined speed, and finally pressurized to achieve the extrusion function of the die-casting process of the molten metal, which suppresses the generation of cavities in the die-cast product and enhances the mechanical performance. Then, the die-cast product is solution-treated and then hardened, artificially aged (that is, T6-treated) to give weldability, the strength and elongation of the die-cast product are improved, and the high quality of the die-cast product is improved. Guaranteed and therefore less investment through simple horizontal cold chamber die casting machine modifications in many areas, high performance and weight reduction of product components can be achieved, important for weight reduction, energy saving and environmental protection of motor vehicles Not only does it play a key role, but it also opens up new processes.
