Description

A barrel mixing mechanism for an injection molding machine

technical field

The utility model relates to the field of injection molding machine parts, in particular to a barrel mixing mechanism for an injection molding machine.

Background technique

Injection molding machine is also known as injection molding machine or injection molding machine. It is the main molding equipment for making thermoplastics or thermosetting plastics into various shapes of plastic products using plastic molding dies. Divided into vertical, horizontal, all-electric. The injection molding machine can heat the plastic and apply high pressure to the molten plastic, so that it is shot out and fills the mold cavity. The outer wall of the cylinder is heated to make the plastic melt, and then the machine closes the mold and moves the injection seat forward to make the nozzle close to the gate of the mold. The molten material is injected into the closed mold with low temperature under pressure and fast speed. After a certain period of time and pressure maintenance (also known as pressure holding) and cooling, the mold can be opened and the product can be taken out. Prevent the backflow of molten material in the mold cavity, replenish material into the mold cavity, and ensure that the product has a certain density and dimensional tolerance). The basic requirements of injection molding are plasticization, injection and molding. During injection molding, the mixing of raw materials can affect the quality of the product.

For the existing mixing mechanism of the barrel of the injection molding machine, the mixing is uneven and the mixing efficiency is low, thus affecting the quality of the product. Therefore, a mixing mechanism with uniform mixing and high mixing efficiency is required.
