Injection mold and demolding method thereof

Abstract

The invention discloses an injection mold and a demolding method thereof. Through the injection mold and the demolding method thereof, the problem that parts are difficult to take out due to the factthat ejector pins get stuck in products in the prior art is solved. The injection mold comprises a base, a mold body arranged on the base and an ejection device used for ejecting a product out of themold body. The ejection device comprises an ejection mechanism used for ejecting the narrow edges of the product or deep ribs on the periphery of the product and a demolding mechanism used for ejecting the product out of the mold body. The injection mold has the advantages of improving the injection molding production efficiency and injection molding quality, and the mold manufacturing cost and later maintenance cost are reduced.

Description

technical field [0001] The invention relates to the field of mold forming, more specifically, it relates to an injection mold and a demoulding method thereof. Background technique [0002] At present, home appliances, automobiles, medical and 3C electronic products all use plastic injection molding parts, and plastic injection molding parts need to be formed through injection molds. Some products are limited by structural features. After the product is ejected, the local features cannot be completely separated from the demoulding mechanism, which makes it difficult to take the product, thereby reducing the production efficiency of the product. [0003] Usually, this type of mold needs to be ejected twice to solve the problem of difficulty in taking out the product, but the second ejection will make the mold structure complex, the manufacturing cost is high, and the difficulty of mold maintenance is increased. Moreover, when the product is mass-produced, it is necessary to a...

AI Technical Summary

Problems solved by technology

Some products are limited by structural features. After the product is ejected, the local features cannot be completely separated from the demoulding mechanism, which makes it difficult to take the product, thereby reducing the production efficiency of the product.

[0003] Usually, this type of mold needs to be ejected twice to solve the problem of difficult product removal, but the second ejection will make the mold structure complex, the manufacturing cost is high, and it will increase the difficulty of mold maintenance

Moreover, when the product is mass-produced, it is necessary to add a release agent regularly, which not only makes the injection molding production efficiency low, but also increases the scrap rate of the product

The use of release agent not only affects product quality, but also pollutes the environment
