[0002] A casting mold refers to making the structural shape of a part in advance with other materials that are easy to form, and then placing the mold in a sand mold. Thus, a cavity with the same structural dimensions as the part is formed in the sand mold. Then, a fluid with fluidity is poured into the cavity, and after the fluid cools and solidifies, a part with exactly the same shape and structure as the mold can be formed. A casting mold is an important part of the casting process.

[0003] The existing casting molds include an upper mold and a lower mold. When in use, the upper mold and the lower mold are clamped together, so that materials can be injected into the cavity between the upper mold and the lower mold, and then molding is carried out in the cavity of the mold.
