An injection molding machine capable of automatic quantitative feeding

Abstract

This application relates to an injection molding machine capable of automatic quantitative feeding, which includes an injection molding device and a feeding device, and the feeding device includes a material channel, a metering cylinder, a recovery channel, a first blocking member and a second blocking member; The material channel is arranged obliquely, with the upper end being the feeding end, the middle part being provided with a material outlet, and the lower end being a recycling end; the upper end of the metering cylinder is facing the feeding port, the lower end is facing the injection molding device feeding port, and the side part is provided with a recycling port. The upper end of the recovery channel is facing the recovery end, and the lower end is facing the recovery port; the first blocking member is arranged at the lower end of the metering cylinder, and is used to control the opening and closing of the lower end of the metering cylinder; the second blocking member is arranged at the Between the recovery channel and the quantitative cylinder, and used to control the opening and closing of the lower end of the recovery channel. This application adopts the method of quantitative volume to measure the required amount of plastic particles, and the excess plastic particles can be recycled for the next quantitative feeding, which has the advantages of fast, convenient and accurate feeding.

Description

An injection molding machine with automatic quantitative feeding technical field [0001] The application relates to the field of plastic parts production equipment, particularly relates to a kind of automatic quantitative feeding injection molding machine. Background technique Plastic parts are plastic accessories, which can be used in various fields, among which the most common ones are connectors, and plastic parts are used as bases for connecting terminal is inserted. Plastic parts are mainly formed by injection molding. The specific process is as follows: plastic powder such as PVC and PA66 (or plastic granules) and calcium carbonate and other fillers are mixed evenly, and then pour the mixture into the injection molding machine (ie injection molding machine), and the plastic is hot melted. After injection, the mold cavity is filled, and the plastic part is obtained by demoulding after plastic molding. [0003] The injection molding machine has a one-time molding o...

AI Technical Summary

Problems solved by technology

[0004] The feeding of injection molding machine is generally carried out manually, and the required weight of plastic particles is weighed and put in from the feeding port, which is time-consuming and laborious, and needs to be improved.
