Plastic rubber forming mold of inner cap of cosmetic bottle

Abstract

The invention discloses a plastic rubber forming mold of an inner cap of a cosmetic bottle. The plastic rubber forming mold of the inner cap of the cosmetic bottle comprises a fixed mold, a movable mold, a feeding port and a cooling water flow channel, wherein a fixed template of the fixed mold is provided with a guide sleeve in which a movable guide post is inserted; the guide post is fixed on a movable template of the movable mold; the movable mold is opened or closed through the guide post; the movable mold and the fixed mold are correspondingly engaged to form two forming cavities which are symmetrically arranged along an axial line of the movable template; the forming cavities with open upper openings are conversely frustum-shaped; the upper openings of the forming cavities are approximately elliptic; two ends of the elliptic upper openings are short straight sides; the circular arc sides of the upper openings are provided with clamping groove cavities; the lower openings of the forming molds are sealed ends; and the surfaces of the sealed ends are elliptic. Through the way mentioned above, the plastic rubber forming mold of the inner cap of the cosmetic bottle, disclosed by the invention, has the advantages of molding the inner cap of the cosmetic bottle rapidly, improving production efficiency of the plastic rubber mold as the inner caps of two bottles can be processed, improving a rate of finished products, lowering production cost and avoiding resource waste.

Description

technical field [0001] The invention relates to a plastic forming mold, in particular to a plastic mold for forming the inner cap of a cosmetic bottle. 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. Plastic mold is a tool for producing plastic products. According to different production processes and products, it can be divided into: injection molding mold, blowing mold, rotational molding mold and thermoforming mold, etc. In the traditional concept, two sets of molds are generally required , because a set of molds has only one parting surface, which constitutes...

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.

The size and assembly of cosmetic bottle inner caps on the existing market require that the plastic parts have high dimensional accuracy and molding interface. The existing plastic molds have low molding efficiency and low yield, which greatly increases production costs and wastes resources.
