Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a zinc alloy automobile parts forming mold. Background Art

[0002] The main added elements of zinc alloys are aluminum, copper and magnesium. Zinc alloys can be divided into two categories according to the processing technology: deformation zinc alloys and casting zinc alloys. Cast zinc alloys have good fluidity and corrosion resistance and are suitable for die-casting instruments, automobile parts casings, etc.

[0003] The existing referenceable Chinese utility model patent with announcement number: CN208825510U discloses a zinc alloy part forming die, including an upper die plate and a lower die plate, the inner cavities of the upper die plate and the lower die plate are both provided with a die groove, the top of the inner cavity of the upper die plate is fixedly connected with a forming panel, the inner cavity of the forming panel is provided with an electric heater, and the inner walls of the upper die plate and the lower die plate are fixedly connected with a heating shell. The utility model uses a shunt pipe for buffering to prevent the metal liquid from flowing too fast during forming and affecting the quality after forming. During the injection process, the electric heater and the heating shell are started to perform secondary processing on the raw material so that it can be evenly distributed in the mold to prevent excessive gas from appearing. The small amount of gas generated can be recovered through the reflux pipe for liquid recovery or emitted through the air vents. After the liquid is evenly distributed, the electric heater and the heating shell are turned off to allow the stock liquid to be naturally formed under the action of the die groove and the forming panel to complete the production of the product.

[0004] After the existing die-casting molds are poured with molten metal, they need to spend a long time waiting for the molten metal to cool and set, which is inefficient. In addition, the contact points between the existing die-casting molds and the hydraulic equipment during the die-casting process are mostly located in the center of the top mold or the bottom mold, which causes a difference in the pressure on the periphery of the casting and the pressure on the center during the die-casting process, which may cause a difference in density between the center and the periphery of the casting after molding.
