Plastic mold for molding baffle of water-drop-shaped electric heater

Abstract

The invention discloses a plastic mold for molding a baffle of a water-drop-shaped 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 movable mold and the fixed mold form a molding cavity after occluding correspondingly; the molding cavity is a water-drop-shaped plane sheet cavity; a small locating bayonet cavity is arranged in the position, close to the top arc, at the upper end of the molding cavity; a straight-sided cavity is arranged at the lower end of the molding cavity; two rectangular locating bayonet cavities with downward openings are arranged on the straight-sided cavity; and a fixed clamp hook cavity is arranged in the position, close to the middle position between the two rectangular locating bayonet cavities, on the plane of the molding cavity. 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 the 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 plastic mold for forming a partition of a drop-shaped electric heater. Background technique [0002] In recent years, with the rapid development and general use of the plastics industry, the strength and precision of engineering plastics have been continuously improved, making the application range of plastic products also expanding, such as household appliances, instruments and meters, construction equipment, automobile industry, Japan, etc. In many fields such as hardware, the proportion of plastic products is increasing rapidly. With the increasing demand for plastic products, higher requirements are placed on the output of plastic molds. However, in terms of existing mold technology, in order to improve production efficiency, it can only be achieved by adding injection molding machines and mold equipment, which will not only increase hardware costs, but also the corresponding equi...

Problems solved by technology

However, based on the existing mold technology, in order to improve production efficiency, it can only be realized by adding injection molding machines and mold equipment, which will not only increase the hardware cost, but also the corresponding equipment maintenance costs and the consumption of electric energy, water energy and other operating costs. And labor costs are not a small expense. Therefore, the huge increase in production costs has seriously limited the development of the plastics industry.

[0003] The bulkhead of the drop-shaped electric heater on the existing market requires the plastic part to have 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
