Convenient-discharging injection molding system

Abstract

The invention relates to a convenient-discharging injection molding system. The convenient-discharging injection molding system comprises a plurality of injection molding machines, material sub-cylinders and a main material cylinder, the material discharging end of the main material cylinder is connected with the plurality of injection molding machines, the material sub-cylinders are arranged at the front ends of the injection molding machines, a spiral feeder is arranged at the front end of every material sub-cylinder, every spiral feeder comprises a shell, a motor and a spiral blade, a material inlet is arranged at the upper end part of the left side of every shell, a material outlet is arranged at the lower end part of the right side of every shell, a rotating rod is coaxially arrangedin every shell, the rotating shafts are coaxially provided with the spiral blades, and the rotating shafts are driven by the motors arranged at the left sides of the shells to rotate. The system allows the main material cylinder to provide a raw material for the material sub-cylinders in a unified manner, so the automatic feeding purpose is achieved, and manpower is saved. The spiral feeders in the system act as valves, guarantees uniform and stable feeding and blocking preventing, and also can secondarily dry the raw material to effectively improve the quality of an injection molded part.

Description

technical field [0001] The invention belongs to the technical field of moulds, in particular to an injection molding system which is convenient for discharging materials. Background technique [0002] Injection molds are plastic products made of thermoplastic or thermosetting granular materials into various shapes. The production process of plastic products is as follows: feed the raw materials into the barrel, and after the raw materials are dried, they are sent to the injection molding machine for melting and plasticization, and high pressure is applied to the molten plastic to make it inject and fill the mold cavity. [0003] Each injection molding machine is equipped with a barrel. The disadvantages of this structure are: first, the raw materials in the barrel need to be filled manually, so a lot of manpower is wasted and labor costs are increased; usually a solenoid valve is installed at the inlet of the injection molding machine , but the solenoid valve is easy to blo...

[0003] Each injection molding machine is equipped with a barrel. The disadvantages of this structure are: first, the raw materials in the barrel need to be filled manually, so a lot of manpower is wasted and labor costs are increased; usually a solenoid valve is installed at the inlet of the injection molding machine , but the solenoid valve is easy to block the material, thus affecting the injection quality
