[0002] As the equipment connecting the injection molding machine and the AGV, the machine side is usually large in number. This leads to the need to consider its cost and structural complexity. It needs to be low-cost, simple in structure, easy to install, and adjustable.

[0003] Most of the existing peripheral equipment of injection molding machines are composed of square tubes and sheet metal parts connected by welding, threading and other connection methods, and then matched with electric rollers and other rollers; the lifting methods are mostly motor-driven chains or cylinder lifting, etc. This not only makes the structure more complicated, but also increases the manufacturing cost and makes the installation and debugging work more difficult. The welding and threaded connection methods have too many restrictions, making the machine edge unadaptable and inflexible. Once installed, it is difficult to adapt to other solutions.

[0004] At the same time, the existing lifting methods of the machine side are mostly motor-driven, manual foot-operated, or cylinder-lifting, and their functional flexibility is poor. Utility Model Content
