A kind of plastic parts production equipment and its production process

Abstract

The invention discloses a production equipment for plastic parts, the key points of the technical solution include a feeding mechanism and an injection molding machine, the feeding mechanism includes at least two material storage devices, a measuring device, and a stirring device, and the measuring device includes A support frame, a collection box is arranged above the support frame, a measuring cylinder and a partition plate are arranged in the collection box, and the partition plate divides the inner cavity of the collection box into an upper chamber and a lower chamber and is provided with A through hole for the measuring cylinder to pass through, an electric valve is connected to the bottom of the measuring cylinder, and a second screw conveyor extending above the stirring device is connected to the bottom of the collecting box. The measuring cylinder can automatically weigh a certain volume of raw materials, which saves time and effort compared with manual weighing. Since the raw materials of plastic parts are generally granular or powdery, with small particle size and good fluidity, the volume measurement method will not have a large error rate due to the void ratio.

Description

technical field [0001] The invention relates to the field of plastic accessories, in particular to a plastic part production equipment and a production process thereof. Background technique [0002] Plastic parts are plastic accessories, which can be used in various fields, the most common of which are connectors, and the plastic parts are used as bases for connecting terminals to insert. Plastic parts are mainly molded by injection molding. The specific process is as follows: mix PVC, PA66 and other plastic powder (or plastic granules) and fillers such as calcium carbonate evenly, and then pour the mixed material into the injection molding machine (ie, injection molding machine). After hot-melting, it is injected to fill the mold cavity, and after the plastic is molded, it is demoulded to obtain a plastic part. [0003] The Chinese patent whose notification number is CN101348001B discloses an injection molding machine, namely a horizontal injection molding machine. [000...

AI Technical Summary

Problems solved by technology

At present, the weighing of various raw materials is generally carried out manually, and then the materials are mixed and stirred evenly, which is time-consuming and laborious, and needs to be improved.
