A stepless tapered nano brush head molding die

Abstract

The invention relates to a stepless conical nanometer toothbrush head forming mold by using which the mold manufacturing cost and the mold manufacturing period are reduced; and the service life of the mold is long. The stepless conical nanometer toothbrush head forming mold sequentially comprises a top plate, a plate A, a front mold insert, a rear mold insert, a plate B, a rear mold ejector pin, a cushion block, an ejector pin plate, an ejector pin supporting plate and a bottom plate from top to bottom, a spring and a plate A fixed distance screw are connected between the top plate and the plate A, a containing groove I is formed in the bottom surface of the plate A, the front mold insert is arranged in the containing groove I, a containing groove II is formed in the top surface of the plate B, and the rear mold insert is arranged in the containing groove II; the front mold insert and the rear mold insert are arranged oppositely, a plurality of mold cavities and a runner groove for communicating all the mold cavities are formed between the front mold insert and the rear mold insert, the rear mold ejector pin penetrates through the ejector pin plate, the plate B and the rear mold insert sequentially and is communicated with the mold cavities of the rear mold insert. The quality and the production efficiency of a nanometer toothbrush are improved, the service life of the mold is prolonged and the automatic production capacity of the mold is promoted.

Description

technical field [0001] The invention relates to a nanometer toothbrush, in particular to a molding die for a stepless tapered nanometer brush head. Background technique [0002] At present, in the field of toothbrushes in the industry, nano toothbrushes have been quite popular. The basic structure of the toothbrush is to use a brush head and bristles [0003] Manufactured by one-shot injection molding. However, in the prior art, the step-shaped round bristles are processed by slow wire cutting, the single shape of the bristles and the long mold processing cycle, high processing costs, low production efficiency and other factors restrict the development of nano toothbrushes and The quality and beauty of the product. Contents of the invention [0004] Aiming at the above problems, the present invention provides a stepless tapered nano-brush head molding die which can reduce the manufacturing cost and cycle of the die and improve the service life of the die. [0005] The t...
