Industrial 300 Ton Auto Parts Injection Molding Machine With Silicone Feeding System

Machine Control System:

1.  Hydraulic control system

The hydraulic system is used to power the machine and is the "blood" circulation system of the injection machine. It is the circuit that provides pressure and speed to the various actuators (working cylinders) of the injection machine. The hydraulic circuit generally consists of a main circuit that controls the pressure and flow of the system and a sub-circuit of each actuator. The proportional control valve and the electronic servo system are used to implement closed-loop feedback control of the control system of the injection machine, which further improves the control precision and has a good human-machine interface.

2.  Electrical control system

The electrical control system is the "central nerve" system of the injection machine, which controls the various procedures and actions of the injection machine, and controls and adjusts the awakening time, position, pressure, speed and number of revolutions, mainly by electronic components and detection components. And the composition of automated instruments.

3. Temperature control

• The temperature control system mainly includes a feeding area, a screw barrel, a syringe, a cold runner, a heating plate and the like. The temperature of each of the above systems is controlled by a dedicated temperature regulation circuit. The temperature control of the screw cylinder, the injection cylinder and the cold runner is controlled by a dedicated temperature control unit, and the heating and cooling medium has two kinds of hot oil and water.
• Temperature is one of the main control parameters during the rubber injection molding process. The early temperature is adjusted by “on/off” and proportional differential (PD) adjustment. Currently, it is developed to precise temperature proportional integral (PID) adjustment. The PID adjustment system can not only adjust the temperature as quickly as the proportional adjustment, but also like the integral. Eliminating the residual temperature deviation, it can also advance the action according to the variation of the temperature deviation like the differential adjustment, so as to suppress the expansion of the deviation, the accuracy and stability of the temperature adjustment can be greatly improved, and the requirements of the rubber injection molding process conditions can be better met.
• In recent decades, rubber injection molding machines and injection molding processes have been continuously improved and improved, making them more and more widely used in the rubber industry. With the development of modern electronic technology and computer technology, the control system of rubber injection molding machine has also achieved continuous development and improvement. For mass-produced products such as auto parts and electrical and electronic equipment parts, rubber injection molding machines can give full play to the advantages of injection molding. The use of injection molding technology to innovate the production technology used in current production will be one of the research topics in the rubber industry. With the development of China's rubber processing industry, the use of more advanced rubber injection molding machines can achieve high production efficiency, high product quality, create high economic benefits, and open up broader prospects.
