Scatter-point recombination mold for one-time molding of spherical plastic net

Abstract

The invention discloses a scatter-point recombination mold for one-time molding of a spherical plastic net, which belongs to the field of moulds. The mold is located above the lower mold, and the inner scatter ball mold is located inside the upper mold and the lower mold. The inner walls of the upper mold and the lower mold are fixedly connected with a plurality of evenly distributed mold hole columns, and the multiple mold hole columns are connected to the inner scatter ball mold. Matching, it can control multiple scattered point mold pieces to separate from the expansion and contraction mold skeleton, and at the same time control the expansion and contraction mold skeleton to give up the volume reduction, and take the inner scattered point spherical mold out of the spherical plastic net in a way of breaking it into parts, so that Reduce the convenience of demoulding. Compared with the existing technology, the spherical plastic net can be fully formed with only one injection, effectively reducing the number of injection molding and the steps of later bonding, significantly reducing the workload, and improving the spherical shape. Preparation efficiency of plastic mesh.

Description

technical field [0001] The invention relates to the field of moulds, more specifically, to a scattered-point recombination mold for one-time molding of spherical plastic nets. Background technique [0002] Injection molding, also known as injection molding, is a molding method of injection and molding. The advantages of the injection molding method are fast production speed, high efficiency, automatic operation, various designs and colors, simple to complex shapes, large to small sizes, accurate product sizes, easy replacement of products, and complex shapes. Parts, injection molding is suitable for mass production and complex-shaped products and other molding processing fields. At a certain temperature, the completely molten plastic material is stirred by a screw, injected into the mold cavity with high pressure, and cooled and solidified to obtain a molded product. method. This method is suitable for mass production of parts with complex shapes and is one of the important...

AI Technical Summary

Problems solved by technology

[0003] Due to its own characteristics, when performing injection molding, considering the convenience of demoulding, the spherical plastic net is usually divided into upper and lower parts, and two injection moldings are performed, and then the two formed plastic parts Welding or bonding together to form a complete spherical plastic mesh structure, however, this multiple molding method not only increases the overall molding workload, but also leads to low preparation efficiency of the overall spherical plastic mesh
