Problems solved by technology

However, during the production of existing molds, the parts in contact with the metal mold are easily scratched and crushed by the metal mold, resulting in scratches on the surface of the product and unsightly appearance; Product contact will cause the product to be deformed by heat, and functional areas such as the functional layer on the product will also be damaged due to high temperature, which reduces the yield of the product and causes an increase in defective production

Embodiment Construction

[0011] see figure 1 and figure 2 Shown, a kind of overmolding molding mold of the present invention, its structure comprises upper mold 1, and the lower mold 2 that cooperates with upper mold 1, and the mold cavity 3 that is arranged on upper mold 1 and lower mold 2, and with The mold cavity 3 matches the insert 4, and the rubber layer 6 is provided at the contact between the mold cavity 3 and the product 5. Since the rubber layer 6 is provided at the contact between the cavity 3 and the product 5, when the product is reprocessed through the mold, the product will not be scratched or crushed by the metal mold in the mold, which effectively improves the molding effect ; It can reduce the temperature in the mold, protect the product, improve the yield of processed products, and because the functional layer on the product is not damaged, good functions are guaranteed and production defects are reduced.

[0012] Wherein, the thickness of the rubber layer 6 is 1-2MM, which plays...

Abstract

The invention discloses a rubber coating forming mould, comprising an upper mold, a lower mold matched with the upper mold, cavities arranged on the upper mold and the lower mold and mould inserts matched with the cavities, wherein, a rubber layer is arranged at the contact part of the cavities and products. As the rubber layer is arranged at the contact part of the cavities and products, the products can not be scratched and crushed by a metal mould when reprocessed by the mould, thereby effectively improving forming effect; the rubber coating forming mould can reduce the temperature in the mould, reduces the risk of deformation of the products at high temperature, increases finished product ratio of process products, guarantees good functions due to the functional layers on the productsare not damaged, and reduces bad production.

Description

technical field [0001] The invention relates to an overmolding mold. Background technique [0002] With the improvement of people's requirements for product appearance and the needs of the product itself, some products now need to be reprocessed after being formed by plastic, hardware and other molds. If the product is molded by plastic, it is necessary to inject a layer of silica gel on some parts of the product to meet the needs of use. However, during the production of existing molds, the parts in contact with the metal mold are easily scratched and crushed by the metal mold, resulting in scratches on the surface of the product and unsightly appearance; Product contact will cause the product to be deformed by heat, and functional areas such as the functional layer on the product will also be damaged due to high temperature, reducing the yield of the product and causing an increase in defective production. Contents of the invention [0003] The technical problem to be ...
