The function of the clamping system is to ensure that the mold is closed, opened, and finished. At the same time, after the mold is closed, the mold is provided with enough clamping force to resist the pressure of the molten plastic into the cavity of the mold cavity to prevent the mold from being slotted and cause the bad situation of the product. The composition of the clamping system is mainly composed of a clamping device, a cutter, a mould adjusting mechanism, a ejection mechanism, a front and rear fixed template, a movable template, a mould clamping cylinder and a safety protection mechanism.
Second, hydraulic system
The role of hydraulic transmission system is to achieve the injection molding machine in accordance with the requirements of the various processes to provide power, and to meet the requirements of various parts of the injection molding machine pressure, speed, temperature, etc.. The utility model is mainly composed of hydraulic components and hydraulic auxiliary components, wherein the oil pump and the motor are the power sources of the injection molding machine. A variety of valves to control oil pressure and flow, so as to meet the requirements of injection molding process.
Third, electrical control
The electric control system and hydraulic system can be used to realize the process requirements (pressure, temperature, speed, time) and all kinds of program actions. Mainly by the electrical appliances, electronic components, instrumentation (see right), heaters, sensors and other components. Generally, there are four kinds of control modes: manual, semi-automatic, automatic and adjustment.
Fourth, heating / cooling system
The heating system is used to heat the material cylinder and the injection nozzle, and the cylinder of the injection molding machine is generally used as a heating device. Heat transfer through the wall of the cylinder provides the heat source for the material plasticization; the cooling system is mainly used to cool the oil temperature, the oil temperature is too high will cause a variety of faults, so the oil temperature must be controlled. Another place that needs to be cooled is near the material inlet of the feed pipe, so as to prevent the material from melting in the material inlet.
Fifth, lubrication system
Lubrication system is the injection molding machine of movable mould, mould adjusting device and a connecting rod hinge, Radio Taiwan etc. relative motion spot to provide lubrication loop, in order to reduce the energy consumption and improve the service life of the parts, lubrication can be manual lubrication regularly, can also be automatic lubrication;
Sixth, safety monitoring system
The safety device of injection molding machine is mainly used to protect the safety of human and machine. The utility model is mainly composed of a safety door, a safety baffle, a hydraulic valve, a limit switch, a photoelectric detecting element, etc., and realizes the interlock protection of the electrical machinery hydraulic system. The monitoring system is mainly used to monitor the oil temperature, material temperature, system overload, and process and equipment failure of the injection molding machine.
