Plastics forming technique by plastics melting, mold closure, be injected into the continuous flow procedure that the operations such as mould, pressure keep, goods solidify, mold closing takes out main product form, hydraulic system is in order to guarantee plastic-injection moulding machine by technical process predetermined requirement and operation program, carries out work accurately and the power and the control system that arrange.
Control system be mainly that effect is to carry out sequential control and process control, control the order of injection cycle and maintenance process temperature, time, pressure and speed in setting value, control system can be selected operator scheme manually or automatically.
As preferably, described control system is comprised of hydraulic motor, hydraulic valve, electromagnetic relay, temperature sensor, approach switch, grating switch, threephase asynchronous machine, monitoring display device and PLC controller.
As preferably, this mold closing mechanism also comprises safety door and mould adjusting mechanism.
As preferably, this heating control system also is provided with power regulating eqiupment and temperature sensor.
As preferably, described Plasticized component is colloidal sol cylinder, spiral shell cylinder or nozzle.
As preferably, described control system is the PLC control system.
Plastics automatic moulding machine of the present invention can be processed various thermoplasticity or thermosetting plastics, and feed particulate material is pressed into barrel through screw rod, after heat fused, under certain injection speed and pressure, be expelled in mould, be frozen into very soon needed plastic products after pressurize.
The invention has the beneficial effects as follows: the plastics automatic moulding machine, technology in conjunction with power control system, motion control system and heating control system realizes production process, coordinate simultaneously the meaning of the application of PLC in control system for shot machine to be: to improve the quality of products, alleviate labor strength, suitably reduce the operating technology level.Raise labour productivity, reduce the quantity of bad goods, accelerate capital turnover, area is produced in reduction, and energy savings consumption reduces product cost; Improve product's dimensional precision and stability, raising speed, shortening molding cycle, the automation of production process and more laborsaving.
