Moulding plastic mould for upper cover of foundation bottle

Abstract

The invention discloses a moulding plastic mould for an upper cover of a foundation bottle. The moulding plastic mould for the upper cover of the foundation bottle comprises a fixed die, a movable die, a feeding hole and a cooling water runner, wherein a fixed die plate of the fixed plate is provided with a guide sleeve, a movable guide pillar is inserted into the guide sleeve, the guide pillar is fixed on the movable die plate of the movable die, and the movable die does open and close development by virtue of the guide pillar; the movable die and the fixed die are corresponding occluded to form two moulding cavities, the two moulding cavities are symmetrically distributed along a lateral axis of the movable die plate, each moulding cavity is a square box-like cavity the upper end face of which is provided with openings, four sides of each moulding cavity are cambered surfaces protruding outward, the inner wall of the side of each moulding cavity is provided with two symmetrical side clamping and hooking cavities, and the side clamping and hooking cavities are arranged at the inner edge of the opening on the upper end face of each moulding cavity. By adopting the manner, a production process can be simplified, the actual production is more convenient and efficient and more human and material resources can be saved, so that the base moulding plastic mould disclosed by the invention is applicable to flow line production of a product, production cost is saved, and production efficiency of an enterprise is greatly improved.

Description

technical field [0001] The invention relates to a plastic forming mold, in particular to a plastic mold for forming the upper cover of a foundation bottle. 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 volume and assembly of the top cover of the foundation bottle on the market require that the plastic part has high dimensional accuracy and molding interface. The conventional inject...

AI Technical Summary

Problems solved by technology

The shape of the product is also various. The size and assembly of the top cover of the foundation bottle on the existing market require that the plastic part has high dimensional accuracy and molding interface. The conventional injection mold is designed to mold one piece, but The maximum daily output can only reach 1,500 pieces. For example, if the daily output is 5,500 pieces, it is necessary to add a corresponding number of 3 sets of one-cavity molds, 3 sets of injection molding machines, and 6 personnel. The input cost is very large, and Plastic molds have low molding efficiency and low yield, which greatly increases production costs and wastes resources
