Embodiment Construction

[0016] In order to clarify the technical scheme and technical purpose of the present invention, the present invention will be further introduced below in conjunction with the accompanying drawings and specific implementation methods.

[0017] As shown in the figure, it is an injection mold for processing high-glossy products. The injection mold is provided with a heating oil circuit 1 and a cooling water circuit 2 in the fixed mold. A product cavity 3 is provided in the fixed mold. The product cavity 3 The bottom of the mold is a plane, which is the part used to form the high glossy surface of the product.

[0018] Below the product cavity 3, a number of oil branch pipes of the heating oil circuit 1 are distributed at a distance of 9-11 mm from the bottom of the product cavity, and 10 mm is the preferred distance setting. The branch pipes of the oil circuit are parallel to each other and have the same length, and the branch pipes are equidistantly arranged. Both ends of each ...

Abstract

The invention discloses an injection mould for machining highly-glossy products, which is characterized in that the injection mould is provided with a heating oil path and a cooling water path in a fixed mould, wherein the heating oil path is arranged at one side close to the highly-glossy surfaces of the moulded products in a mould cavity, and located between a product cavity and the cooling water path. According to the injection mould disclosed by the invention, plastic is heated via the heating oil path, thus overcoming the defect of the upper temperature limit of common water paths, so that the products can obtain good glossy and smooth effects.

Description

technical field [0001] The invention relates to a mold, in particular to an injection mold suitable for processing high glossy products. Background technique [0002] When processing high-gloss surface products, it is usually necessary to heat the plastic, especially for rubber materials with high viscosity and difficult to glue. After heating, the fluidity of the colloid will be enhanced to make the surface of the product smooth and bright after molding. If the water is heated, the water will vaporize when it exceeds a certain temperature, so the heating effect is limited, and the bright effect of the injection molded product is not good. Contents of the invention [0003] The technical purpose of the present invention is to provide an injection mold for processing high-glossy products through an oil passage. [0004] Technical scheme of the present invention: [0005] An injection mold for processing high-gloss products, characterized in that the injection mold is prov...
