Technical Field

[0001] The utility model relates to the technical field of die-casting molds, in particular to a sheet metal die-casting mold. Background Art

[0002] Die casting is a metal casting process characterized by the use of high pressure to apply molten metal to the mold cavity. The mold is usually made of a stronger alloy and the process is somewhat similar to injection molding. Most die castings are non-ferrous, such as zinc, copper, aluminum, magnesium, lead, tin, lead-tin alloys and their alloys. Depending on the type of die casting, a cold chamber die casting machine or a hot chamber die casting machine is required.

[0003] When die-casting sheet metal, it is often necessary to replace the mold core and mold cavity of corresponding size according to the size of the required sheet metal. The mold cavity and mold core are set on the upper mold and the lower mold. In the prior art, the upper mold and the lower mold are fixed to the mold by multiple bolts. It is very time-consuming and labor-intensive to replace, which reduces production efficiency. Therefore, we have introduced a sheet metal die-casting mold. Utility Model Content
