[0002] Die-casting molds are tools for casting metal parts, and are used to complete the die-casting process on a dedicated die-casting forging machine. The basic process of die-casting is: the molten metal is first cast and filled into the mold cavity at a low or high speed. The mold has a movable cavity surface, which is pressurized and forged as the molten metal cools, eliminating the shrinkage defects of the blank and making the internal structure of the blank reach the broken grains of the forged state. Die-casting molds are needed in the processing of automotive parts.

[0003] During use of the existing die-casting mold, the molten metal is introduced into the upper mold through the liquid filling hole at the upper end, and then flows into the lower mold. However, there is a small amount of air in the upper and lower molds, and the presence of air can easily cause quality problems of auto parts after die-casting. At the same time, there is a density difference between the molten metal in the upper and lower molds when the liquid is inletted into a single casting hole, which reduces the quality of the auto parts after die-casting, thereby causing the existing die-casting mold to have usage defects.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] A die-casting mold for automobile parts processing disclosed in the present invention is mainly applied to existing die-casting molds. During use, molten metal is introduced into the upper mold through the liquid adding hole at the upper end, and then flows into the lower mold. However, there is a small amount of air in the upper and lower molds. The presence of air can easily cause quality problems of automobile parts after die-casting. At the same time, there is a density difference between the molten metal in the upper and lower molds when liquid is inletted into a single casting hole, which reduces the quality of automobile parts after die-casting.

At the same time, during the rotation of the scraper 1210, the vibration rod 1214 is started, and the vibration rod 1214 makes the scraper 1210 in a vibrating state, thereby avoiding a certain amount of loss caused by the adhesion of high-temperature liquid, thereby further reducing the loss.
