Hemispherical upper cover injection mould of powerful flash light

Abstract

The invention discloses a hemispherical upper cover injection mould of a powerful flash light, which comprises a fixed mould, a movable mould, a feed inlet, and a cooling water channel; a guide sleeve is mounted on a fixed mould plate of the fixed mould; a movable guide post is inserted in the guide sleeve; the guide post is fixed on a movable mould plate of the movable mould; the movable mould performs opening-closing movement through the guide post; two moulding cavities are formed by corresponding engaging of the movable mould and the fixed mould; the two moulding cavities are symmetrically arranged along the fixed mould plate longitudinal axis; main parts of the moulding cavities are rectangular cavities with downward-turning edge cavities; the centers of the rectangular cavities are hemispherical cover cavities protruding upwardly; the turning edge cavities at the four corners of each rectangular cavity are in circular arc transition. With the above mode, the hemispherical upper cover of a powerful flash light is moulded rapidly; two hemispherical upper covers of powerful flash lights can be processed at one time; the production efficiency of plastic moulds is improved; the yield is increased; the production cost is decreased; and resource waste is prevented.

Description

technical field [0001] The invention relates to a plastic forming mold, in particular to an injection mold for a hemispherical upper cover of a flashing lamp. Background technique [0002] Plastic molds are tools used to shape objects, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material. With the continuous development and progress of science and technology, plastic molding products are widely used in modern commodities, such as computers, mobile phones, cars, digital cameras, game consoles, cosmetics, refrigerators, etc. And these products have higher and higher requirements on the product molding quality of each spare parts. The shape of the product is also various. The bottom cap of the cosmetic bottle on the existing market is a commonly used product. Its volume and assembly require that the plastic part has high dimensional accuracy and moldin...

AI Technical Summary

Problems solved by technology

The shape of the product is also various. The bottom cap of the cosmetic bottle on the existing market is a commonly used product. Its volume and assembly require that the plastic part has high dimensional accuracy and molding interface. The existing plastic mold has low molding efficiency and the finished product The rate is low, which greatly increases the production cost and wastes resources
