Description

Technical Field

[0001] The utility model relates to the technical field of molding dies, in particular to a molding die which is easy to demould. Background Art

[0002] Moulds are an indispensable tool in modern industrial production. They can produce highly consistent products on a large scale and with high efficiency. They are widely used in various fields such as automobiles, electronics, aerospace, and home appliances.

[0003] When molding a product with a through hole on the side, a molding boss needs to be set in the cavity of the lower mold. When the lower mold and the upper mold cooperate to form a cavity, the molding boss presses against the upper mold to form a through hole when molding the product. In order to ensure the sealing performance between the molding boss and the upper mold and prevent the molding medium from entering between the molding boss and the upper mold, the molding boss needs to fit tightly against the upper mold. This causes serious wear between the molding boss and the upper mold, and the maintenance cost is high. After the product made in the mold is molded, when the product is taken out of the mold, the molding boss will hinder the demolding, seriously affecting the production efficiency.

[0004] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.
