What are the components of a fully automatic injection molding machine?

(1) Electrical control system
The electrical control system and hydraulic system are properly coordinated to meet the process requirements (pressure, temperature, speed, time) and various program actions of the needle machine. Mainly composed of electrical appliances, electronic components, surfaces, heaters, sensors, etc. There are generally four control methods, manual, semi-automatic, fully automatic, and adjustment.
(2) Hydraulic transmission system
The function of the hydraulic transmission system is to provide power for various actions required by the process of the fully automatic injection molding machine, and to meet the requirements of pressure, speed, temperature, etc. required for each part of the fully automatic injection molding machine. It is primarily composed of various hydraulic components and auxiliary hydraulic components, with the oil pump and motor being the power source of the fully automatic injection molding machine. Various valves control the oil pressure and flow rate, and then meet the requirements of the injection molding process.
(3) Mold closing system
The function of the mold closing system is to ensure that the mold is closed, open, and ejected from the product. At the same time, after the mold is closed, a satisfactory locking force is supplied to the mold to resist the mold cavity pressure generated by molten plastic entering the mold cavity, avoiding mold slits and forming a defective situation of the product. Composition of the mold closing system: The mold closing system is mainly composed of mold closing equipment, mold adjustment organization, ejection organization, front and rear fixed templates, mobile templates, mold closing cylinders, and safety protection organization.

(4) Injection system
The injection system is one of the most important components of fully automatic injection molding machines, generally consisting of three main methods: plunger type, screw type, and screw pre molded plunger injection. The screw type is now widely used. Its function is to heat and plasticize a certain amount of plastic at a regular time during a cycle of the injection molding machine. Under a certain pressure and speed, the molten plastic is injected into the mold cavity through a screw.
(5) Heating/cooling system
The heating system is used to heat the material barrel and injection nozzle. The fully automatic injection molding machine generally uses an electric heating coil as the heating equipment for the material barrel, which is installed outside the material barrel and detected by thermocouples in sections. Heat conduction through the cylinder wall provides a heat source for material plasticization; The cooling system is primarily used to cool the oil temperature. Excessive oil temperature can cause various problems, so it is necessary to control the oil temperature. Another direction that requires cooling is near the discharge port of the material pipe, to prevent the material from melting at the discharge port, which may cause the material to not be discharged properly.
(6) Lubrication system
The lubrication system is a circuit that provides lubrication conditions for parts with relative motion such as the moving template, mold adjustment equipment, and connecting rod hinge of a fully automatic injection molding machine, in order to reduce energy consumption and improve the lifespan of parts. Lubrication can be done manually on a regular basis or automatically through electric lubrication;
(7) Safety monitoring system
The safety equipment of fully automatic injection molding machines is primarily used to protect human and machine safety. It mainly consists of safety doors, hydraulic valves, limit switches, photoelectric detection components, etc., completing the interlocking protection of electrical, mechanical, and hydraulic systems. The monitoring system primarily monitors the oil temperature, material temperature, system overload, and process and equipment defects of the fully automatic injection molding machine, and indicates or alarms any abnormal situations.
