Description

Technical Field

[0001] The utility model relates to the technical field of injection molding machines, in particular to a plastic injection molding machine which is easy to assemble and disassemble. Background Art

[0002] Injection molding machine is a plastic molding equipment that can transform plastic particles into plastic products of specific shapes. Its working principle is to add plastic particles into the heated barrel of the injection molding machine. Through heating and compression, the plastic is melted into a flowing state. Then, under high pressure, the molten plastic is injected into the mold and cooled to form the desired plastic product.

[0003] The injection assembly is the core part of the injection molding machine. Its main function is to inject plastic particles into the mold. It includes a motor, an injection seat moving cylinder, and a screw drive device (melt motor). When inspecting the injection assembly of the injection molding machine, it is generally necessary to remove the entire screw drive device from the motor seat so that the screw drive device can be inspected. In this disassembly and assembly method, since one end of the screw drive device is tightly connected to the injection hole at one end of the mold, it is also necessary to use the injection seat moving cylinder to move the entire injection assembly so that one end of the screw drive device is separated from the injection hole at one end of the mold, and the injection seat on the injection molding machine moves. When the cylinder is in use, the injection seat moving cylinder will work in a high temperature environment. If the temperature is too high, the oil inside the cylinder will deteriorate, thus affecting the normal operation of the cylinder. In addition, the injection seat moving cylinder works under high pressure. If the pressure is too high, the oil inside the cylinder will leak, thus affecting the normal operation of the cylinder. At the same time, the injection seat moving cylinder requires regular maintenance and care. If the maintenance is improper, the oil inside the cylinder will deteriorate or leak, thus affecting the normal operation of the cylinder. Therefore, the injection seat moving cylinder is used to realize the movement and fixation of the entire injection molding assembly, which makes the injection molding machine have certain production risks when in use.
