Abstract
The invention discloses an injection molding machine screw rod which comprises a rod body, an injection nozzle and a positioning key. The positioning key and the injection nozzle are connected to thetwo ends of the rod body. The injection nozzle comprises a conical head, a connecting shaft, a cement passing ring and a gasket. The connecting shaft comprises a first threaded section, an installation section and a second threaded section. The installation section is located between the first threaded section and the second threaded section. The connecting shaft penetrates the cement passing ringand the gasket, and the cement passing ring is arranged close to the conical head. The cement passing ring and the gasket are located on the installation section, the first threaded section is connected with the conical head, and the second threaded section is connected with the rod body. Alloy layers are arranged on the outer surface of the rod body, the outer surface of the injection nozzle andthe outer surface of the positioning key. The invention further discloses a preparing method of the injection molding machine screw rod. The injection molding machine screw rod is resistant to corrosion and wear, the conical head and the cement passing ring are conveniently replaced, and the cost is saved.
Description
technical field [0001] The invention relates to the field of injection molding equipment, in particular to an injection molding machine screw and a preparation method thereof. Background technique [0002] The screw of the injection molding machine is one of the key components of the injection molding machine. When it is working, it rotates in the barrel to melt and plasticize the solid polymer particles or powder, store and measure, and then inject a certain amount of molten plastic into the mold. Molding, after the mold is cooled, it is ejected, and the plastic product can be obtained. The plasticizing ability and adaptability to special molding materials of existing injection molding machine screws often have various deficiencies, and there is a problem of poor plasticizing quality of products. The screw rods in the prior art have the defects of being prone to corrosive damage and easy wear. Generally, the wear of the screw head and the apron is serious. Once the screw h...
