Heavy-load type stacking unit of mold transfer trolley

Abstract

The invention discloses a heavy-load type stacking unit of a mold transfer trolley. The heavy-load type stacking unit comprises a guide column, a top frame at the top end of the guide column and a traction machine, wherein a fixed pulley is arranged on the top frame; a lift car is arranged on the guide column in a sliding fit mode, the lift car is provided with a movable pulley, and the lift car is further provided with a fork mechanism; a traction rope of the traction machine is wound around the fixed pulley and the movable pulley to form a pulley block; the fork mechanism comprises a telescopic arm, a tray used for containing a mold is placed on the telescopic arm, and the telescopic arm comprises a fixed arm, a transition arm and a sliding arm; the fixed arm, the transition arm and thesliding arm are in multi-stage transmission through a first gear, a first upper rack, a lower rack, a second gear and a second upper rack; and the fixed arm, the transition arm and the sliding arm bear the weight through a first sliding groove, a lower guide wheel, a second sliding groove and an upper guide wheel. The heavy-load type stacking unit can effectively lift and transversely move the tray so as to complete stacking of the heavy-load type mold.

Description

technical field [0001] The invention relates to the technical field of heavy-duty mold storage and placement mechanical equipment for auto parts in the auto parts industry, in particular to a heavy-duty stacking unit of a mold transfer vehicle. Background technique [0002] In the auto parts industry, many molds used for die-casting auto parts are heavy-duty molds, generally weighing 2.5t to 3t, and some molds even weigh 5t. In consideration of saving floor space, the mold racks for storing the above-mentioned heavy molds in the warehouse should adopt a multi-layer stacked structure, that is, there are multi-layer shelf units on the mold rack, and different molds can be put into shelves with different heights. units, stack and shelve to save floor space. [0003] The problem faced by this application is to put the mold on the pallet and put the pallet on the transfer car, and how to design the specific mechanism on the transfer car after driving the transfer car to the desi...

AI Technical Summary

Problems solved by technology

Specifically, if you want to move molds of ordinary weight, you can also set up a stacking unit driven by cylinders or oil cylinders on the transfer vehicle, but because the die-casting molds in the auto parts industry are too heavy, it is impossible to drive and carry such a large-tonnage mold with a cylinder. Even if a large oil cylinder is used for the mold, the load may meet the requirements, but the volume and weight of the stacking unit are too large, which will cause the overall weight and volume of the transfer vehicle to be too large, making the transfer vehicle bulky, occupying a large area, and high energy consumption. poor practicality
