Forming plastic mould for temperature sensing head cover of refrigerator

Abstract

The invention discloses a forming plastic mould for a temperature sensing head cover of a refrigerator. The forming plastic mould comprises a fixed mould, a movable mould, a feeding opening and a cooling water flow channel; a guide sleeve is installed on a fixed mould plate of the fixed mould; a movable guide post is inserted into the guide sleeve and fixed on a movable mould plate of the movable mould; the movable mould is used for carrying out opening-closing movement through the guide post; four forming cavities are formed after the movable mould and the fixed mould are correspondingly hinged, the four forming cavities are in rectangular and symmetrical arrangement, and the four forming cavities are shaped as boxes with upper open end faces; two ends of the forming cavities are arc sides, and the rest two sides are straight sides; buckle cavities are formed in the arc sides and the straight sides; a plurality of elongated air through hole cavities are formed in the bottom surfaces of the forming cavities; and four temperature sensing head buckle cavities are arranged in the positions keeping away from the air through hole cavities in the bottom surfaces of the forming cavities. In the way, the temperature sensing head covers of the refrigerators can be quickly formed; and four lamp rear covers are processed at the same time, so that the production efficiency of the plastic mould is enhanced, the yield is improved, the production cost is reduced and the resource waste is avoided.

Description

technical field [0001] The invention relates to a plastic forming mold, in particular to a plastic mold for forming a temperature-sensitive head cover. 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 temperature-sensitive head cover of the refrigerator on the existing market is a commonly used product. Its volume and assembly require that the plastic part has high dimensional accurac...

AI Technical Summary

Problems solved by technology

The shape of the product is also various. The temperature-sensitive head cover of the refrigerator 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. The yield rate is low, which greatly increases the production cost and wastes resources
