Integrated brush and integrated brush injection mold

Abstract

The invention discloses an integrated brush and its injection mold. The integrated brush includes a brush handle and brush filaments. The brush handle is molded by injection molding, and is integrally formed with the brush filaments through injection molding. The integrated brush The injection mold of the injection mold comprises a fixed mold and a movable mold, the fixed mold is installed on the bottom of the fixed template, the movable mold is installed on the upper part of the movable template, guide columns are arranged on the top surface of the movable template, and the movable template The bottom of the bottom is connected with a support column and a base in turn, and a push shaft is sleeved in the base, and the top of the push shaft has a push plate, a push rod and a push rod guide rod in turn. The invention integrates the brush handle covered with the brush wire through the injection molding process, the bonding is firm and reliable, the material can be directly remelted and utilized, the waste of resources and equipment cost investment are reduced, the product specifications are relatively uniform, and the production efficiency is high.

Description

technical field [0001] The invention relates to the technical field of hair brushes, in particular to an integrated hair brush and an injection mold thereof. Background technique [0002] The brush is one of the more commonly used tools in daily life and industrial production. The brush is mainly composed of a brush handle and a brush wire embedded in the brush handle. The brush wire is generally made of plastics such as nylon, PBT, PET, PVC and PP. Silk, a brush made of man-made fiber micro raw materials, has the advantages of stable quality, unlimited length, and various colors. Of course, the most important thing is low production cost; It is fixed by beading, hot-melt glue, etc., and then the assembled semi-finished product is placed on the stamping and forming equipment to complete the final occlusal molding. The brush handle is generally made of metal sheet to form a steel ring after stamping, flanging, bending and cutting, which requires a complete set of processing ...

AI Technical Summary

Problems solved by technology

The brush handle is generally made of metal sheet to form a steel ring after stamping, flanging, bending and cutting, which requires a complete set of processing equipment, and the investment cost of the equipment is relatively high, and the process of embedding the brush wire into the metal brush handle is generally done by manual cutting. , the work efficiency is low, the labor intensity is high, and the cutting effect varies from person to person, the product specifications are difficult to unify, the connection between the brush wire and the brush handle is not reliable, and the phenomenon of loosening and shedding is prone to occur, which reduces the service life of the brush. The formed steel ring brush handle cannot be recycled and can only be treated as scrap steel, which greatly wastes resources and increases the cost of material input
