Description

Technical Field

[0001] The utility model relates to the technical field of injection molding machines, and particularly relates to a movable injection molding and ejection mechanism. Background Art

[0002] An injection molding machine is a commonly used plastic molding machine, mainly including an injection system, a mold clamping system, a drive system, and a control system. These systems cooperate with each other to complete the molding of plastic parts. Among them, the ejection mechanism is an important part of the injection system. Generally, the nozzle of the material pipe needs to be docked with the mold inlet for injection. However, in the existing ejection mechanism, the central positions of the nozzle of the material pipe and the mold inlet are pre-processed and assembled according to fixed positions, and the position cannot be adjusted. Therefore, there are many position matching tolerances, which always results in a deviation between the center of the nozzle and the center of the mold inlet, leading to leakage of glue at the joint between the nozzle and the mold inlet, thus affecting production. In addition, once the material pipe is damaged, it is not convenient to disassemble, install, and replace. Content of the Utility Model
