Abstract
The injection molding machine is an equipment that thermosetting or thermoplastic plastic can be made into all kinds of plastic parts. Plastic industry and its molding machinery industry are emerging parts. Injection molding machine plicated in plastic processing machinery and precision of the machine. At present, with the development of the machine productivity and automation production, plastic parts have been increasingly widely used in national defense, electrical, aviation, machinery, science,education,culture,health and so on.
The content of this paper is mainly for the design of injection molding machine injection parts, relevant chapters of the content will be introduced with the topic background and significance,
In chapter 1, the paper summarizes the injection molding machine with the injection part of the design and optimization research present situation, which is elaborated and based on CAD. The paper also puts forward the basic framework of this paper.
In chapter 2, the paper introduces the plasticizing unit, the screw, cylinder head, and analyses the classification of advantages and disadvantages.
In chapter 3, the paper introduces the design of the injection cylinder, and studies the injection cylinder diameter, also with the diameter of the piston rod, which includes the calculation of its size.
In chapter 4, the paper introduces the transmission part of the design. It can withstand the torque and rotate speed which is studied, and the paper also introduces
