Background

The die casting process is to press molten metal into a precise metal mold cavity at high speed by using high pressure, and the molten metal is cooled and solidified under the action of pressure to form a casting.

The die casting die is used for casting liquid forging, and a movable cavity surface of the die is pressed and forged along with the cooling process of molten metal so that the molten metal is solidified into a die casting. The die-casting die mainly comprises a movable die plate, a movable die, a fixed die plate and a fixed die, wherein the fixed die is fixedly arranged on the fixed die plate, the movable die is fixedly arranged on the movable die plate, and the movable die covers the fixed die and forms a die-casting cavity.

In the cold chamber die casting process, molten metal is poured into a die chamber by a manual or automatic pouring device, and then an injection punch head moves forward to press the molten metal into a die cavity. In the hot chamber die-casting process, a pressure chamber is vertical to a crucible, molten metal automatically flows into the pressure chamber through a feed inlet on the pressure chamber, and an injection punch moves downwards to push the molten metal to enter a cavity through a gooseneck. And after the molten metal is solidified, opening the die-casting die, taking out the casting and completing a die-casting cycle.

In the mass production of products, because the arrangement of ejector pin in the die cavity is unreasonable, the ejector pin is very near from the lateral wall of seal groove, when leading to the product ejecting, the easy meat deficiency damage of seal groove, and the rejection rate is extremely high with the rate of reprocessing, increases manufacturing cost, for this reason, we provide one kind and prevent the damaged ejecting structure of seal groove meat deficiency.
