The plasticizing device of injection moulding machine is generally equipped with an integral rotating mechanism. When assembling and disassembling the screw nozzle, screw and barrel of the injection moulding machine, the positioning screw of the injection moulding base should be loosened first to deflect it from the original position at a certain angle, so that the barrel axis of the injection moulding base can avoid the axis of the clamping device, so as to facilitate the disassembly, assembly and maintenance of the screw and barrel of the injection moulding machine.
A. Removal of screw nozzle of injection moulding machine
If there is any residual material in the barrel, it should be heated to the plasticizing temperature first, and the high thermal stability polyolefin resin or special cleaning material for the barrel should be used to fully clean the barrel at high speed, and the residual melt can be discharged as far as possible before the disassembly work can be carried out. Since the residual material in the nozzle part can not be discharged completely, the nozzle or the head of the barrel should be heated before the nozzle is disassembled. After the injection machine screw nozzle is heated up, the special hammer is used to knock it loose. The bolt should not be loosened completely. When it is loosened to 2/3, it is lightly knocked. After the internal gas is released, the nozzle is unloaded. Cleaning the screw nozzle of injection moulding machine should be carried out at high temperature while it is hot, so as to remove the residual melt from the nozzle hole in the runner. The method is to inject demoulding agent from the nozzle to the inside, i. e. to drip the demoulding agent from the side of the nozzle thread to the material and the inner wall surface, so that the material and the inner wall are separated, and the material is taken out from the nozzle.
B. Maintenance and repair of screw nozzle of injection moulding machine
If the contact part between nozzle and positioning sleeve of die occurs unilateral contact or bad contact in production, the spherical R part of front end will be deformed, forming a groove for melt escape, resulting in overflow at nozzle, and the caliber part will also be deformed. Therefore, overflow should be checked and repaired in time. C. The threaded parts of the nozzle should be inspected regularly and the sealing surface on the side of the barrel should be replaced in time if serious wear or corrosion is found. D. Check the internal passage of screw nozzle of injection moulding machine. The surface quality of the melt strip can be observed by air injection moulding, and the residual melt discharged from the nozzle can more accurately reproduce the runner condition in the nozzle. The residual amount and temperature distribution of the melt in the nozzle can be analyzed.
