Plastic forming die for inner upper covers of eye cream bottles

Abstract

The invention discloses a plastic forming die for inner upper covers of eye cream bottles. The plastic forming die for the inner upper covers of the eye cream bottles comprises a fixed die, a moving die, a feed port and a cooling water runner. An inclined wedge block is arranged on a fixed template of the fixed die, is matched with a moving inclined wedge groove block of the moving die, and moves in an inclined wedge groove of the moving inclined wedge groove block. The moving inclined wedge groove block is movably connected to a moving template of the moving die. The moving die is opened and closed through the moving inclined wedge groove block. The moving die and the fixed die are correspondingly joined to form two forming die cavities which are symmetrically formed along the lateral axis of the moving template. The forming die cavity form bowl shapes with elliptical upper openings with annular overturned edges on which small bayonet piece cavities are symmetrically formed. In such a way, the inner upper covers of the eye cream bottles can be quickly formed, the inner upper covers of two bottles can be machined at the same time, the production efficiency of the plastic forming die is improved, yield is also improved, production cost is lowered, and resource waste is avoided.

Description

technical field [0001] The invention relates to a plastic forming mold, in particular to a plastic mold for forming an inner upper cover of an eye cream 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 upper lid of the eye cream bottle on the existing market require that the plastic part has high dimensional accuracy and molding interface. The conven...

Problems solved by technology

The shape of the product is also various. The volume and assembly of the upper lid of the eye cream 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. However, 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 injection molding machines, and 6 personnel. The input cost is very high. Moreover, the molding efficiency of plastic molds is low, and the yield rate is low, which greatly increases production costs and wastes resources.
