Abstract

The invention relates to the field of plastic injection molding, in particular to a reciprocating type melting device capable of achieving quantitative compaction for injection molding. The technical problem to be solved by the invention is to provide the reciprocating type melting device capable of achieving quantitative compaction for injection molding, and the reciprocating type melting device can effectively flatten and compact injection molding particles, extrude bubbles and reduce gaps. The reciprocating type melting device capable of achieving quantitative compaction for injection molding comprises a mounting frame, a compaction assembly, a quantification assembly, a discharging assembly, a flattening assembly and the like. The compaction assembly is fixedly connected to the mounting frame, the discharging assembly is mounted on the outer side of the mounting frame, the quantification assembly is arranged on the discharging assembly, the flattening assembly is fixedly connected to the outer side of the mounting frame, a heating pipe is fixedly connected to the bottom of the mounting frame, and an eduction pipe is arranged on the heating pipe. An operator starts an electric push rod, quantitative material distribution can be carried out, then the effect of quantitative discharging is achieved, when the electric push rod is started to be shortened, the effect of compacting injection molding particles is achieved, and gaps and spaces between the plastic particles can be reduced.

Description

technical field [0001] The invention relates to the field of plastic injection molding, in particular to a reciprocating melting device capable of quantitative compaction for injection molding. Background technique [0002] Plastic injection molding is a method of plastic products. The molten plastic is injected into the mold of the plastic product under pressure, and cooled and formed to obtain various plastic parts. The most commonly used plastic is polystyrene. There are mechanical injection molding machines dedicated to injection molding. However, the existing injection molding machines cannot effectively flatten and compact the injection molding particles and extrude air bubbles, resulting in poor quality injection molding products. Contents of the invention [0003] In order to overcome the shortcomings of existing devices that cannot effectively flatten and compact injection molding particles and squeeze out air bubbles, the technical problem to be solved by the i...
