Mold frame plate balanced lifting device

Abstract

The invention relates to a mold frame plate balanced lifting device. The mold frame plate balanced lifting device comprises angle supporting blocks, connecting rods, tightening and fixing mechanisms and lifting mechanisms; the angle supporting blocks are provided with first through grooves and second through grooves; the cross sections of the connecting rods are matched with the first through grooves and the second through grooves; the tightening and fixing mechanisms are positioned on the side surfaces of the angle supporting blocks and correspond to the first through grooves and the second through grooves in position; the lifting mechanisms are positioned on the angle supporting blocks and comprise hydraulic cylinders and lifting hooks; and the lifting hooks are detachably connected withpiston rods of the hydraulic cylinders through steel wire ropes. According to the mold frame plate balanced lifting device, mold frame plates in various sizes can be lifted under the condition of lacking a crane, so that the mold frame plates are conveniently placed on a handcart, the labor intensity is reduced, and the mold frame plates are prevented from being damaged.

Description

technical field [0001] The invention relates to the field of formwork production, in particular to a formwork plate balanced lifting device. Background technique [0002] The mold base is the support of the mold. For example, on the die-casting machine, the parts of the mold are combined and fixed according to certain rules and positions, and the part that enables the mold to be installed on the die-casting machine is called the mold base. It consists of a push-out mechanism, a guide mechanism, and a pre-reset mechanism. Composed of mold foot pads and seat plates. [0003] The formwork is composed of multiple layers of formwork boards. Most of the formwork boards are made of metal, and the whole is relatively heavy, so its own weight is relatively large, and the four corners are equipped with lifting rings for easy lifting; during the handling process, it needs to be lifted to the hand-drawn in the car. [0004] However, in the case of outdoors or without a crane, most of...

AI Technical Summary

Problems solved by technology

[0004] However, in the case of outdoors or without a crane, the existing lifting methods are mostly manual use of iron rods to lift one end of the formwork board, and then gradually increase the height and place it on the trolley

This method has more inconveniences in the actual operation process, which will lead to greater labor intensity, and the use of iron rods is easy to damage the outer surface of the formwork board
