Compacting table for casting moulding

Abstract

A compacting table for casting moulding comprises a roller way frame, supporting rollers and a supporting roller driving mechanism. A compacting frame is arranged in the roller way frame, a vibrating motor is arranged on the lower portion of the compacting frame, supporting beams which are transversely arranged among the supporting rollers are arranged at the upper end of the compacting frame, spring assembling seats protruding out of the left side face and the right side face of the compacting frame are distributed on the lower portion of the compacting frame, a rubber air spring is arranged on the lower side of each spring assembling seat, a rubber spring is arranged on the upper side of each spring assembling seat, each rubber air spring and the corresponding rubber spring form a spring combination, a compacting frame seat is arranged on one side of each spring combination, the lower end of each rubber air spring corresponding to the corresponding compacting frame seat is fixed on th eupper side of a bottom seat body at the lower end of the corresponding compacting frame seat, and the upper end of each rubber spring corresponding to the corresponding compacting frame seat is matched with the lower side of an upper seat body at the upper end of the corresponding compacting frame seat. By the compacting table, moulding quality and efficiency can be improved effectively, equipment noise and influence on a workshop foundation during vibration can be reduced substantially.

Description

technical field [0001] The invention relates to casting molding mechanical equipment, in particular to a vibration table for casting molding. Background technique [0002] At present, the vibrating table used by the molding and core wire vibrating department of the foundry industry generally has the following three forms. [0003] 1. Rubber air spring lifting vibration isolation form. This form of vibrating table relies on the inflation and exhaust of rubber air springs to ensure the lifting of the vibrating frame. This form of vibrating table vibrates when the vibrating frame is working. The table cannot be kept level, and the molding sand is not evenly compacted. [0004] 2. Cylinder lifting rubber composite spring vibration isolation form. This form of vibrating table relies on the inflation and exhaust of the cylinder to ensure the lifting of the roller frame, while the vibrating frame itself remains unchanged, and the excitation force of the vibration motor is the high...

Problems solved by technology

[0003] 1. Rubber air spring lifting vibration isolation form. This form of vibrating table relies on the inflation and exhaust of rubber air springs to ensure the lifting of the vibrating frame. This form of vibrating table vibrates when the vibrating frame is working. The table top cannot be kept level, and the molding sand is not evenly compacted

[0004] 2. Cylinder lifting rubber composite spring vibration isolation form. This form of vibrating table relies on the inflation and exhaust of the cylinder to ensure the lifting of the roller frame, while the vibrating frame itself remains unchanged, and the excitation force of the vibration motor is the highest. It is easy to be transmitted to the equipment foundation, causing the surrounding equipment and buildings to vibrate together, affecting the lives of the surrounding residents

[0005] 3. Cylinder lifting polyurethane rubber plate vibration isolation form. This form of vibrating table relies on the inflation and exhaust of the cylinder to ensure the lifting of the roller frame. Similarly, the vibrating frame itself remains unchanged, and the excitation of the vibration motor The force is also the easiest to transmit to the equipment foundation, and the amplitude is relatively small, so it is not easy to adjust

It will also cause surrounding equipment and buildings to vibrate together, affecting the lives of surrounding residents
