Plastic mold for molding rear body of electric heater

Abstract

The invention discloses a plastic mold for molding a rear body of an electric heater. The plastic mold comprises a fixed mold, a movable mold, a feeding hole and a cooling water flow channel, wherein a guide sleeve is installed on a fixed mold plate of the fixed mold; a movable guide pillar is inserted in the guide sleeve and is fixed on a movable mold plate of the movable mold; the movable mold does open and close movements via the guide pillar; the fixed mold and the movable mold form a molding cavity after occluding correspondingly; the molding cavity is a sheet cavity shaped like an elongated box; heat dissipation cover cavities shaped like fences are arranged on the bottom surface of the sheet cavity shaped like the elongated box and protrude outward to form a cambered surface; the heat dissipation cover cavities shaped like fences extend to two longer side cavities of the sheet cavity shaped like the elongated box; and six screw installing hole cavities distributed in two rows are arranged on the surfaces of the heat dissipation cover cavities shaped like fences. The plastic mold has the beneficial effects that the plastic mold can simply the production processes and simultaneously save more human and material resources, is suitable for assembly line production of products, saves the production cost and greatly improves the production efficiency of the enterprises.

Description

technical field [0001] The invention relates to a plastic forming mold, in particular to a rear body forming plastic mold of an electric heater. Background technique [0002] Mold is an important process equipment for industrial production. Plastic mold is a tool used to shape objects. 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. With the improvement of people's living standards, electric heaters have entered ordinary households, washing machines are constantly being updated and improved, and related parts of electric heaters are also being improved accordingly. To attract consumers has gradually become the goal pursued by every electric heater manufacturer in the market. The volume and assembly of the rear bo...

AI Technical Summary

Problems solved by technology

The volume and assembly of the rear body of the electric heater on the existing market requires that the plastic part has high dimensional accuracy and molding interface. The existing plastic mold has low molding efficiency and low yield, which greatly increases the production cost. a waste of resource
