Description

A die-casting molding device for copper castings

Technical field

The utility model relates to the field of copper casting production, and relates to a die-casting forming device for copper castings.

Background technique

Die casting is a metal casting process, which is characterized by using a mold cavity to apply pressure to the molten metal. Copper castings refer to pure copper or copper alloy equipment and devices obtained by casting. When the existing new copper casting molding machine is used, the liquid or semi-liquid metal will first be filled into the cavity of the die-casting mold (die-casting mold) at a high speed, and then formed and solidified under pressure to obtain the casting, but its solidification and cooling The hardening time is long, and workers need to wait for the temperature to drop before taking it. This results in low work efficiency and wastes a lot of waiting time. At the same time, when high-temperature copper castings are placed on the lower mold for a long time, it is easy to affect the hardness of the lower mold body. The mold will be damaged and the service life of the lower mold will be shortened, resulting in poor practicality and reliability.

Compared with the existing technology, the beneficial effects of the copper casting die-casting forming device of the present invention are:

After the male mold and the female mold are closed, the liquid or semi-liquid metal is introduced into the flow channel and then pushed into the second cavity through the push rod until the first cavity is also filled. The water pump works to move the cooling pipe one and the cooling pipe two. Filling with water cools the area close to the cavity one in the punch and the area two in the concave mold close to the cavity, and then quickly cools the internal copper castings. It also cools the punch and the concave mold to extend the life of the punch and the concave mold. After being driven to the left by the driving mechanism to a certain distance, the cylinder in the material retrieval assembly drives the chuck to move to the designated position, and then the punch is driven by the driving mechanism to move a certain distance to the right, so that the copper casting is pushed into the chuck. The clamping groove is clamped, and the water pump works so that the sprinkler head sprays water to further cool down the copper casting and shorten the waiting time for work.
