Plastic injecting mold for casting system with low power consumption

Abstract

A plastic injection mold with an energy-saving and consumption-reducing pouring system includes a mold base, molding parts, a pouring system, and a dual-purpose sprue bushing for the sprue bushing in the pouring system to shorten the sprue to an optimal length as much as possible. The front end of the sprue sleeve and the stripper plate are separated by a sheath to reduce repeated friction with the stripper plate and improve the service life of the mold. Install a cold material dropper on the stripper plate, use the elastic deformation of the spring to push the piston to bounce the nozzle material off the nozzle push plate, so that the nozzle material will fall off automatically. In order to avoid direct friction between the crochet needles and the stripper plate and reduce damage, a wear-resistant spout hook cover is provided between the stripper plate and the spout hooks. In order to solve the existing hidden gates, side gates, point gates, etc. that damage the product appearance, a number of horn-shaped inlaid inserts are embedded in the female mold, and a horn is set in the horn-shaped inlaid insert. The sprue in the shape of the sprue communicates with the point gate on the female mold and the molding cavity.

Description

Technical field [0001] The invention relates to a plastic mold, in particular to a plastic injection mold with an energy-saving and consumption-reducing pouring system. Background technique [0002] The current three-plate plastic mold generally includes a mold base composed of upper and lower mold plates, mold feet, stripper plates, ejector components, guide posts, and guide sleeves. It is composed of cavity A plate and cavity B plate and is installed in the cavity The molding parts composed of the female and male molds in the A plate and the cavity B, and the pouring system. The function of the gating system is to smoothly and smoothly fill the cavity with the molten plastic, so that the gas in the cavity can be discharged smoothly, and during the filling and solidification process, the pressure can be transmitted to all parts of the plastic part. Obtain tightly organized plastic parts. [0003] The existing gating system generally includes a sprue sleeve, a runner, a nozzle cr...

Problems solved by technology

[0007] The object of the present invention is to provide an energy-saving and consumption-reducing pouring system with short main channel, automatic drop-off of nozzle material, no damage to product appearance at the gate position, no need for reprocessing after molding, reinforced mold movable parts and easy replacement and maintenance. Plastic injection molds to solve the problems in the existing plastic injection mold gating system that the main channel is too long, the nozzle material is difficult to fall off automatically, the crochet needle at the nozzle is easy to move, the gate damages the product appearance or the gate position needs to be reprocessed, Problems such as difficult mold maintenance and long period
