Automatic accumulated material clearing device for accumulation type mould head

Abstract

The invention discloses an automatic accumulated material clearing device for an accumulation type mould head. The automatic accumulated material clearing device comprises accumulation type mould head cylinder bodies (1); an inner core rod is arranged, in an axis direction, in a cavity of each accumulation type mould head cylinder body (1); a material injecting piston (5) is arranged outside each inner core rod; a material injection ring (4) is arranged between the inner wall of each material injection piston (5) and the inner wall of each accumulation type mould head cylinder body (1); a groove (2) connected with the bottom of the material injection ring (4) is arranged, in the peripheral direction, on the position below the inner wall of each accumulation type mould head cylinder body (1); and a discharge hole (3), which communicates with each groove (2), is arranged in the peripheral direction in a position, positioned on each groove (2), of the outer side wall of each accumulation type mould head cylinder body (1). According to the automatic accumulated material clearing device disclosed by the invention, the grooves are formed in the inner wall of the accumulation type mould head cylinder bodies, so that accumulated materials drop into the grooves; and after certain time, the accumulated materials are discharged from the discharge holes, so that the problems of accumulated materials, pasted materials and deposited carbon are solved.

Description

technical field [0001] The invention relates to the problem of the accumulated paste generated due to frequent friction between the automatic cleaning material ring of the accumulation die head and the material storage cylinder and the cylinder wall. Therefore, the problem that the existing accumulative die head cannot automatically remove the accumulated paste is solved. Background technique [0002] Plastic container hollow blow molding products from 20 liters to 1000 liters of hollow containers are generally blow molded by accumulation dies. Generally, accumulation dies are composed of feed section, material cover, material storage cylinder, injection ring, It is composed of inner mandrel, mandrel sleeve, intermediate shaft, distributor, sliding block, injection cylinder, servo cylinder, and inner and outer dies. Due to frequent friction between the injection ring and the wall of the storage tank, material accumulation and paste are likely to occur between the two gaps d...

AI Technical Summary

Problems solved by technology

Due to frequent friction between the injection ring and the wall of the storage tank, material accumulation and paste are likely to occur between the two gaps due to heating and friction, so that black lines, yellow lines, and paste spots often appear on the appearance of the product, which affects product quality. Serious impact, this has caused the accumulation of material, paste, and carbon deposits on the die to be cleaned frequently, which increases the production cost of the enterprise, energy consumption, and waste products, so that the product has no market due to high production costs. Competitive advantage, lost market
