AI Technical Summary

Technical Problem

When existing false eyelash molding equipment uses traditional cold runner injection molding, the plastic in the runner cools and solidifies, becoming waste material, which accounts for a high proportion of the injection molding raw materials. In addition, the traditional water cooling method increases the demand for industrial water.

Method used

A hot runner forming device is used to directly form fibers in the forming zone using hot runners. Instead of water cooling, a fan and humidifier are used for humidification and cooling, reducing the generation of waste material in the flow channel. At the same time, a washing tank is set up to accurately add chemical auxiliaries, ensuring the orderly arrangement of fiber bundles and the cleaning effect.

Benefits of technology

It significantly reduces raw material consumption and waste generation, reduces industrial water demand, improves product performance and consistency, and is environmentally sustainable.

Abstract

This utility model provides a hot runner molding device for false eyelash production, relating to the field of false eyelash molding technology. It addresses the problems of existing molding devices where, in traditional cold runner injection molding, the plastic in the runner cools and solidifies, becoming waste, and the traditional water-cooling method increases the demand for industrial water. The device includes a melt pump connected to a discharge pipe; a conveyor unit inside the mounting box; a hot runner installed on the conveyor unit; the hot runner located inside the molding zone; a fan connected to the top of the cooling zone via a motor; support members on the side of the mounting box; and a water washing tank between the sides of the support members. The hot runner technology completely eliminates the cold runner system. The new process directly molds fibers at the hot runner nozzle, improving product performance and consistency, eliminating runner waste, and significantly reducing raw material consumption costs. By incorporating a fan and humidifier, humidification and cooling of the false eyelashes can be achieved simultaneously, further reducing the demand for industrial water.
