Description

Technical Field

[0001] The present application relates to the technical field of die-casting dies, and in particular to a die-casting die for automobile parts. Background Art

[0002] Die casting mold is a tool for casting metal parts, a tool that completes the die casting process on a special die casting die forging machine. The basic process of die casting is: the molten metal is first cast and filled into the mold cavity at a low speed or high speed. The mold has a movable cavity surface, which is pressurized and forged with the cooling process of the molten metal, which not only eliminates the shrinkage and porosity defects of the blank, but also makes the internal structure of the blank reach the broken grains in the forged state. The comprehensive mechanical properties of the blank are significantly improved.

[0003] The patent document with the publication number CN216656295U discloses: The utility model discloses a die-casting mold for automobile parts, specifically relates to the technical field of die-casting molds, including a lower mold and an upper mold, the upper mold is arranged at the top of the lower mold, the top of the upper mold is provided with a pressure mechanism, the top of the upper mold is provided with a main runner, the inner walls on both sides of the main runner are provided with side runners, the main runner is located at the geometric center of the upper mold, a cavity is formed between the lower mold and the upper mold, the inner walls on both sides of the cavity are provided with grooves, and the grooves are parallel to the main runner. The utility model allows the metal to flow along the main runner into the cavity between the lower mold and the upper mold. Since the main runner is located at the geometric center of the upper mold, the molten metal that flows into the cavity through the main runner reaches each edge of the cavity at roughly the same time, thereby greatly shortening the process and reducing the filling time.
