Plastic rubber forming mold of make-up base transparency cover

Abstract

The invention discloses a plastic rubber forming mold of a make-up base transparency cover. The plastic rubber forming mold of the make-up base transparency cover 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 are semi-enclosed cavities with openings at the upper ends thereof; the openings of the forming cavities are sealed openings which are formed by sequentially connecting two symmetrically distributed circular arc sides and two symmetrically distributed straight sides; the circular arc sides are outwards convex circular arcs; and the movable template is also embedded with a movable mold core in which a straight cooling water flow channel in a lengthways direction is arranged. Through the way mentioned above, the plastic rubber forming mold of the make-up base transparency cover, disclosed by the invention, has the advantages of simplifying production procedures, enabling the practical production to be more convenient and faster, saving human and material resources, being suitable for flow-line production of products, saving production cost and increasing production efficiency of enterprises.

Description

technical field [0001] The invention relates to a plastic forming mold, in particular to a plastic mold for forming a transparent cover of an isolation cream. 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 cons...

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.

[0004] The size and assembly of the barrier cream transparent cover 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 and wastes resources.
