(1) Injection system The effect of the injection system: the injection system is one of the most important components of the Injection Molding Machine
. There are generally three main methods of plunger type, screw type and screw pre-plastic plunger type. The most widely used now is the screw type. The effect is that, in a cycle of the injection molding machine, a certain amount of plastic can be plasticized and plasticized at a predetermined time, and the molten plastic is injected into the mold cavity through the screw at a certain pressure and speed. After the injection is completed, the melt that is injected into the cavity is adhered to the shape. The composition of the injection system: the injection system consists of plasticizing equipment and power transmission equipment.
(2) Clamping system Effect of the clamping system: The effect of the clamping system is to ensure that the mold is closed, opened and ejected. At the same time, after the mold is closed, the mold is given a satisfactory clamping force to resist the cavity pressure generated by the molten plastic entering the cavity, thereby avoiding the opening of the mold and causing the bad condition of the product.
(3) Hydraulic system The effect of the hydraulic transmission system is to complete the various movements required by the High Speed Injection Molding Machine
according to the process, and to satisfy the requirements of pressure, speed and temperature required for each part of the injection molding machine. It is mainly composed of hydraulic components and hydraulic auxiliary components, and the oil pump and motor are the power source of the injection molding machine.
(4) Electrical control system The electrical control system and the hydraulic system are reasonably matched to complete the process requirements (pressure, temperature, speed, time) of the injection machine and various program actions. Mainly composed of electrical appliances, electronic components, appearance, heaters, sensors and so on. There are generally four control methods, manual, semi-automatic, fully automatic, and adjustment.
