Single-motor molding sand vibration device

Abstract

The invention discloses a single-motor molding sand vibration device. The single-motor molding sand vibration device comprises a base (1); a vibration platform (2) is arranged above the base (1); vibration motors (3) are arranged at two ends of the base (1); sand outlets (4) are formed in the side surfaces of the vibration motors (3); separation grooves (5) are formed in the vibration platform (2); screen ports (6) are formed in the separation grooves (5), and are communicated with the sand outlets (4); hydraulic support columns (7) are arranged on two sides of the base (1); gravity inductors (51) are respectively arranged in the separation grooves (5), and are connected with controllers (52); and the controllers (52) are connected with the vibration motors (3) and the hydraulic support columns (7). The single-motor molding sand vibration device has the characteristics of simple structure, elimination of mutual influence between the vibration motors, reduction of the maintenance cost, reduction of the environmental pollution and improvement of the sand removing effect.

Description

technical field [0001] The invention relates to a molding sand vibrating device, in particular to a single-motor molding sand vibrating device. Background technique [0002] At present, after the casting of the parts is completed, the foundry company generally adopts the method of processing the molding sand by placing the sand box on the vibrating device to separate the molding sand from the sand box. However, the existing molding sand vibrating devices usually use dual motors to work, that is, two motors are installed at both ends of the vibrating platform for operation, and the two motors on the same side are connected by a coupling to work at the same time. The structure is relatively complex. When one of the motors fails to work, one end of the coupling will still rotate under the drive of the normal working motor, but the other end of the coupling will not rotate, which will make the coupling easy to break and work normally The motor is also prone to failure, so the ...

AI Technical Summary

Problems solved by technology

However, the existing molding sand vibrating devices usually use dual motors to work, that is, two motors are installed at both ends of the vibrating platform for operation, and the two motors on the same side are connected by a coupling to work at the same time. The structure is relatively complex

When one of the motors fails to work, one end of the coupling will still rotate under the drive of the normal working motor, but the other end of the coupling will not rotate, which will make the coupling easy to break and work normally The motor is also prone to failure, so the existing vibration device will not stop working until another motor fails or the coupling breaks when one motor fails, which greatly increases the maintenance cost and production cost of the enterprise. , reducing the processing efficiency of molding sand

Moreover, the desanding effect of the existing equipment is not ideal, and the sand particles will fly during the desanding process of the existing equipment, causing environmental pollution

Therefore, the existing technology has problems such as complex structure, easy mutual influence of adjacent vibrating motors, high maintenance cost, easy to cause environmental pollution, and unsatisfactory sand removal effect.
