Description

Technical Field

[0001] The utility model belongs to the technical field of molds, and in particular relates to a demoulding device for an automobile die-casting mold. Background Art

[0002] Die casting is a metal casting process characterized by applying high pressure to the molten metal in the mold cavity. The mold is usually made of a higher strength alloy, and the process is somewhat similar to injection molding. Most die castings are iron-free, 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. The mold is an important equipment in the die casting process, and the demolding component is an important component in the die casting mold, which is directly related to the quality of the product. When the existing automotive die casting mold demolding device is used, the die casting parts that are pasted are generally pushed by the ejector pin. However, since the ejector pin is relatively sharp, it is very easy to damage the die casting mold. For this reason, we propose a demolding device for automotive die casting molds.
