Four systems of injection molding machine
The normal operation of the injection molding machine can be ensured only when the various systems of the injection molding machine cooperate well with each other and no failure occurs. Because as long as any of the system problems, will directly lead to the injection molding machine can not operate normally. Here are four common injection molding machine systems: injection system, mold closing system, hydraulic transmission system and electrical control system. Let’s see what effect they have on the injection molding machine.
- Injection system
Injection system is one of the main components of injection molding machine, generally there are three main methods: plunger type, screw type, screw pre-plastic plunger injection type. Now more widely used is the screw type, the effect is that, in a cycle of the injection molding machine, a certain amount of plastic can be heated and plasticized at a specified time, at a certain pressure and speed, the molten plastic will be injected into the mold cavity through the screw. After the injection, the melt injected into the mold cavity is maintained. Composition of injection system: injection system is composed of plasticizing equipment and power transmission equipment.
- mold closing system
The effect of the mold closing system is to ensure that the mold is closed, open and ejection products. At the same time, after the mold is closed, the mold can be given a satisfactory clamping force to resist the pressure of the molten plastic into the mold cavity, so as to avoid the mold opening, resulting in the poor status of the product. Composition of the mold closing system: the mold closing system is mainly composed of mold closing equipment, mold adjusting organization, ejuding organization, front and rear fixed template, moving template, mold closing cylinder and safety maintenance organization.
- hydraulic transmission system:
Provide the power to complete the various movements of the injection molding machine according to the process requirements, and meet the requirements of the pressure, speed, temperature and other parts of the injection molding machine. It is mainly composed of hydraulic components and hydraulic auxiliary components, in which the oil pump and motor are the power source of the injection molding machine, a variety of valves control the oil pressure and flow, and then meet the requirements of injection molding process.
- Manufacturers according to the electrical control system and hydraulic system reasonable coordination, to complete the injection machine process requirements (pressure, temperature, speed, time) and a variety of program action. It is mainly composed of electrical appliances, electronic components, appearance, heaters, sensors and so on. There are generally four control methods: manual, semi-automatic, automatic and adjustment.
The above is a brief analysis of the four systems of injection molding machine manufacturers. More wonderful little information about the device, we will continue to collect, organize and share for you, but also interested friends must pay close attention to our dynamic, so that you can get more details in time.
