Problems solved by technology

[0003] Technical problem: At present, the ejection mechanism of the flow injection mold is easy to cause excessive deformation of injection molded parts that are difficult to demould. It is not suitable for the demoulding treatment of small elastic modulus and thin-walled injection molded parts, and manual cleaning and antirust maintenance are required.

Abstract

The invention discloses an injection mold and a demolding method. The injection mold comprises a mold body, a female mold cavity with a leftward opening is formed in the mold body, a push rod cavity located on the right side of the female mold cavity is formed in the mold body, the opening of the push rod cavity faces leftward, a power cavity located on the upper side of the push rod cavity and in communication with the push rod cavity is formed in the mold body, an air kinetic energy supply mechanism is arranged in the power cavity, a demolding rust-proof mechanism is arranged in the push rod cavity, the demolding rust-proof mechanism can automatically spray a demolding agent before injection molding and enables an injection molding part to be separated from the female mold cavity through leftward movement and reciprocating small-amplitude vibration, therefore, rapid demolding is realized, the pushing force required to be applied to the injection molding part during demolding is reduced, the demolding rust-proof mechanism can spray hot air flow to the demolding rust-proof mechanism and the inner wall of the female mold cavity to clean and spray an anti-rust agent, and rust-proof treatment is achieved. According to the injection mold and the demolding method, and the manual cleaning and maintaining procedures in daily production can be reduced.

Description

Technical field [0001] The present invention relates to the field of injection molding, in particular a injection mold and a demouldable method. Background technique [0002] Injection molding is also known as injection molding, it is a molding method for injection and molding. At present, mainstream injection molds are directly injection molding process, and the push rods are used directly, and it is easy to demold. The injection molded parts produce excessive deformation, not suitable for the removal treatment of elastic modulus and thin-walled injection molding, and manually spray release agents in the process, and manually spraying the mold after injection molding, and completes stopping work Afterwards, manual anti-rust maintenance is required, which is used and inconvenient. Inventive content [0003] Technical issues: At present, the current flow molding mold has an excessive deformation of the injection molded parts that are difficult to demold, and is not suitable for t...
