Injection molding machines belong to one of the classes of plastic machines, originating from the 18 th century. The injection molding machine can divide the machine head into a right-angle machine head, an oblique-angle machine head and the like according to the material flow direction of the machine head and the included angle of the central line of the screw rod. The screw injection molding machine depends on the pressure and the shearing force generated by the rotation of the screw, so that materials can be fully plasticized and uniformly mixed and are molded through a neck mold. Plastic injection molding machines can be classified basically into twin-screw injection molding machines, single-screw injection molding machines and, rarely, multi-screw injection molding machines and screwless injection molding machines.
The injection molding machine can be divided into two parts: one is a power section and one is a heating section. The plastic material enters the injection molding machine from the hopper, is conveyed forward under the drive of the rotation of the screw, and is subjected to the heating of the charging barrel and the shearing and compression actions brought by the screw in the forward movement process to melt the material, so that the change among three states of glass state, high elastic state and viscous state is realized. Under the condition of pressurization, the material in a viscous state passes through a die with a certain shape and then becomes a continuous body with a cross section similar to the die shape according to the die.
