Background

Die casting is a metal casting process and is characterized in that high pressure is applied to molten metal by utilizing the inner cavity of a die. The mold is typically fabricated from a stronger alloy, somewhat similar to injection molding. Most die cast castings are free of iron, such as zinc, copper, aluminum, magnesium, lead, tin, and lead-tin alloys and alloys thereof. Depending on the type of die casting, either a cold chamber die casting machine or a hot chamber die casting machine is required.

The die casting die is a tool for casting metal parts, and is a tool for completing a die casting process on a special die casting die forging machine. However, when the existing die casting die is used, the die is tightly attached to the inner wall of a casting die after die casting molding. Therefore, a spring for demolding is usually arranged in the casting groove, but the reaction force achieved by the spring is limited, when the forming mold with heavy mass is pushed back, the dead weight of the mold and the friction force between the mold and the inner wall are needed to be overcome, so that the lifting height of the mold is limited, the mold cannot be completely separated from the casting groove, and inconvenience is brought to a worker when the mold is demolded.
