As disclosed in the background technology, in the prior art, for the final core box tooling delivery step, the core box trolley needs to realize two actions during operation, front and rear entry and exit, and lifting and lowering with the workbench. The above two actions require high Guidance accuracy, the lifting of the core box trolley relies on the guidance of the workbench, while the entry and exit of the core box trolley needs to rely on the guide rails set on the workbench and the guide rails on the lower core frame to realize the guidance. And because the workbench needs to be raised and lowered, the guide rail and the guide rail are designed in two stages. It is necessary to increase the limit through the part design and the high-demand adaptation of the assembly process to complete the good docking and ensure the smooth operation of the core box trolley. That is to say, the conventional core box tooling usually lays a track under the core box trolley, and at the same time additionally sets a lower top core frame outside the frame, and additionally sets a track on the lower top core frame, which is consistent with the workbench. The rails are level, so that the core box trolley can move from the workbench to the lower core frame, so that the core box tooling can be sent out. However, this two-stage track structure needs to increase the limit through the part design and the high-demand adaptation of the assembly process to complete a good docking. At the same time, the additional frame and track also increase the complexity of the equipment, making it difficult to manufacture and assemble. .
