How to classify the structure of vertical injection molding machine?

Vertical injection molding machine has six systems: injection system, clamping system, hydraulic system/hydraulic transmission system, electrical control system, heating/cooling system, lubrication system.

1: Jetting system is one of the main functions. There are three main forms: plunger type, screw type and screw pre - molded plunger injection type. At present, the screw type is the most widely used. Its role is in the injection molding machine cycle process, in the specified time for a certain amount of plastic heating plasticize, and then the molten plastic with a certain pressure and speed through the screw completely injected into the cavity.

2: the clamping system is mainly composed of clamping device, adjusting mechanism, ejection mechanism, front and rear fixed template, mobile template, clamping cylinder, safety protection mechanism seven parts. The closing system ensures that the mold is closed, opened and ejected. After the mold is closed, provide enough clamping force to the mold to resist the pressure caused by the molten plastic entering the mold cavity, so as to prevent the mold from cracking and causing product defects.

3: hydraulic system/hydraulic transmission system is mainly composed of various hydraulic components and hydraulic auxiliary components. Its power sources are oil pumps and electric motors. Control all kinds of hydraulic pressure and flow, can meet the requirements of various injection molding process. Its function is to provide power for various actions required by the process of the injection molding machine, and to meet a series of requirements of pressure, speed and temperature of each part of the vertical injection molding machine.

4: The electronic control system of the vertical injection molding machine is reasonably coordinated by the electronic control system and the hydraulic system, which can realize the process requirements of the injection molding machine and the coordination of pressure, temperature, speed, time and various program operations. It is mainly composed of electrical appliances, electronic components, meters, heaters, sensors, etc. Manual, semi-automatic, automatic and adjustment are the four commonly used injection control methods.

5: The heating system of the heating/cooling system is mainly used to heat the cylinder body and the nozzle. Generally, the electric heating coil is used as the heating device, which is installed outside the cylinder body, and the situation of the injection molding machine is detected by the thermocouple section. The heat source of material plasticization is formed through the heat conduction of the cylinder wall. The cooling system is mainly used to cool the oil temperature, which will cause a variety of faults. Therefore, the oil temperature must be controlled in time. The cooling position is close to the outlet of the feed pipe to prevent the raw material from melting at the outlet of the feed pipe, leading to abnormal discharge and blockage of the raw material.

6: the role of the lubrication system is to provide lubrication conditions for the moving templates, adjusting devices, connecting rod hinges and other relative moving parts of the vertical injection molding machine. Convenient to reduce energy consumption, improve the life of parts. Lubrication may be regular manual lubrication or automatic electric lubrication.
