Automatic core taking mechanism and core taking method

Abstract

The invention relates to an automatic core taking mechanism which comprises a cylinder, a fixed plate, limiting rods, a guide sleeve, a rubber sleeve, a limiting block and a guide rod. The guide rod passes through a guide hole on the fixed plate to be connected with a piston rod of the cylinder; the guide rod is sleeved with the guide sleeve; the limiting block is arranged at the bottom end of theguide rod; the rubber sleeve connected with the guide sleeve is arranged on the guide rod and above the limiting block; a plurality of vertical downward limiting rods are arranged on the fixed plateand around the guide sleeve. The automatic core taking mechanism has the advantages that the automatic core taking mechanism is simple in structure and ingenious in design; the rubber sleeve is adopted to expand a locking mechanism, and in the clamping process, the guide rod is directly lifted up by the cylinder to compress the rubber sleeve to generate an expansion force, so that the rubber sleeve is in interference fit with a matching hole of a core, thereby implementing clamping. Therefore, the core taking mechanism disclosed by the invention is free to advance or retreat in the core takingprocess without reserving a retreating space in a sand mold, so that the defects of a conventional lifting hook core taking mechanism are overcome, and automatic core taking for a KW line large-sizedcore is implemented.

Description

technical field [0001] The invention relates to a core setting device used on an automatic production line, in particular to an automatic core setting mechanism and a core setting method for realizing the purpose of automatic core setting in the foundry industry, and belongs to the technical field of fixture machinery. Background technique [0002] Casting green sand automation line, taking KW line as an example, belongs to the automatic production line with larger sand box in the casting line. The size of the sand box is 1300×900×400 / 300mm. This molding line is suitable for the production of complex and large castings. The mud cores involved in the production process are also relatively large, and conventional manual handling and core setting are difficult to achieve, and core setting mechanisms are often used. Now the KW line coring is mostly using the hook mechanism, that is, a hanging hole is reserved on the mud core, and the hook is used to hook the hanging hole when ta...

Problems solved by technology

[0007] The object of the present invention is: aiming at the defects in the prior art, an automatic coring mechanism is proposed, and a coring method is provided at the same time. The coring mechanism is firm and reliable, with high core precision and simple operation, which solves the problem of traditional hooks. The core setting mechanism has the disadvantages of high requirements on the shape of the core and the need to reserve a concession space on the sand box
