Fast die changing device for building

Abstract

The invention discloses a fast die changing device for a building. The device comprises a table, wherein a rotating shaft driven to rotate by a first motor is arranged in the table, and the top end ofthe rotating shaft penetrates through the table to be connected to a supporting column. A second motor drives screws on two sides to rotate and threaded blocks are moved above a new die and an old die separately, an air cylinder drives a bushing to move toward the dies to fix the dies, then the first motor drives a rotating shaft to drive the supporting column to rotate, such that the positions of the new and old dies are changed, and therefore, die-changing work is realized. The device can be used for taking out the old die and placing the new die at the same time, and is higher in die changing speed. The bushing is slidably connected to a slide bar in a sleeving manner. By arrangement of a positioning bolt which locks and positions, the device can be suitable for clamping dies of different dimensions. In addition, supporting plates are hinged to two sides of a supporting leg and are positioned by telescopic rods, so that the device is more stable in the die changing process.

Description

technical field [0001] The invention relates to the technical field of building molds, in particular to a quick mold changing device for building molds. Background technique [0002] In the process of building prefabricated buildings, it is necessary to use building molds to produce prefabricated building parts. Different molds are used to produce prefabricated parts in different parts during the production process. Therefore, frequent replacement of molds is required during the production process. , in the process of changing the mold, it is necessary to use the mold changing device to remove the mold on the workbench in time, and then replace another mold to the workbench. This process requires the mold changing device to be able to accurately place the new mold on the On the workbench, and complete the mold change under safe and stable conditions; [0003] Most of the existing mold change devices have a single structure, and the old mold needs to be taken out before the ...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing mold change devices have a single structure, and the old mold needs to be taken out before the new mold can be transferred to the mold table, and the old mold cannot be taken out and the new mold placed at the same time, resulting in a slow mold change speed, thereby reducing the Production efficiency, and most of the clamping mechanisms of the existing mold changing devices have fixed structures, which is not convenient for clamping molds of different sizes, and the practicability is not high. In addition, due to the heavy weight of construction molds, the existing mold changing devices The mold device is not stable enough during the mold changing process, which is prone to safety hazards, and the safety cannot be guaranteed. Therefore, the present invention proposes a quick mold changing device for construction molds to solve the problems existing in the prior art
