Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a mold with a jacking structure. Background Art

[0002] A mold is a tool or device used to make an object of a specific shape. It is usually made of metal, plastic or other materials, has a cavity or concave and convex parts of the desired product, and is used to process raw materials (such as metal, plastic, fiberglass, etc.) into parts, products or objects of a specific shape during the production process.

[0003] An existing Chinese patent (publication number: CN219600245U) proposes a mold, which aims to solve the technical problem that the lower connection of the prior art is easy to break, resulting in the need to replace the mold later and increasing production costs. The mold includes an upper mold, a lower mold and a positioning mold, and is characterized in that: the lower mold is provided with a lower cavity, the positioning mold is provided with a positioning cavity corresponding to the position of the lower cavity and an extension plate extending and entering the positioning cavity, a neck is formed between the extension plate and the positioning mold, a through first insertion hole is provided on the extension plate, and a second insertion hole corresponding to the position of the first insertion hole is provided on the lower cavity, a fixing column is provided above the extension plate, and the fixing column passes through the first insertion hole and the second insertion hole.

[0004] The above technical solution reduces the amplitude of the extension plate by passing the fixed column through the first insertion hole and the second insertion hole, effectively avoids the breakage of the neck, and increases the service life of the positioning mold. However, there is no jacking structure in the above device, and the opening and closing of the mold may need to be adjusted manually or by other means. Deformation or deviation may occur during the opening and closing process, affecting the processing accuracy and quality of the product. Therefore, we propose a mold with a jacking structure.
