Problems solved by technology

Injection molding has specific restrictions on the fluidity of plastics. Due to the effect of pressure during molding, the density of the finished product is high, and the plastic consumed per unit length is more. In addition, after the finished product is demoulded, the process of removing flash edges is added, which increases the cost. , the size of the finished product is limited by the size of the mold. In addition, due to the need to set multiple gates during injection molding, the finished product will be easily broken where the plastics meet
Extrusion molding requires large power of the extruder, low production efficiency, and certain requirements for the fluidity of plastics

Abstract

The invention relates to a rolling style plastic molding machine. It has plastic distributor, mold forming set, several assistant delivery sets and cut off sets from left to the right. There are mold forming roller set installed on the mold molding set that is set at the plastic distributor's outlet, assist delivery set installed at the rear of the mold forming machine, each assistant delivery set installed with assistant drive rolling set, each assistant delivery set having corresponding speed tuning machine, knife frame installed on the first assistant delivery set, edge cutting knife on the knife frame, time sensor on the last assistant delivery machine set, cutting off machine set at the rear of the last assistant delivery machine. It can extend the length of the plastic forming limitlessly, without restraint for the plastic material and its flow feature, realizing continuous production, being able to roll several plastic parts with high production efficiency and fine quality.

Description

Technical field: [0001] The invention relates to the technical field of plastic molding, in particular to a rolling plastic molding machine. Background technique: [0002] Current plastic molding technologies include injection molding and extrusion molding. Injection molding has specific restrictions on the fluidity of plastics. Due to the effect of pressure during molding, the density of the finished product is high, and the plastic consumed per unit length is more. In addition, after the finished product is demoulded, the process of removing flash edges is added, which increases the cost. , the size of the finished product is limited by the size of the mold. In addition, due to the need to set multiple gates during injection molding, the finished product will easily break where the plastics meet. Extrusion molding requires high power of the extruder, low production efficiency, and certain requirements on the fluidity of the plastic. Invention content: [0003] The obje...
