Tailing recycling device for cold-box core shooter and use method thereof

Abstract

The invention provides a tailing recycling device for a cold-box core shooter and a use method thereof, and aims at solving the problem of low efficiency and high working intensity in cleaning residual sand in a shooting barrel after core shooting and manufacturing of a product. The device comprises a main bone and an active material, wherein a sand hanging part for hanging sand is arranged at oneend of the main bone, and a sand core lug for carrying and recycling is arranged at the other end of the main bone; a clamping part which fits the active material is arranged in the middle part of the main bone; the active material is divided into a first active material and a second active material which can be buckled to form an integral active material; and the main function of the active material is to prevent the lug of the main bone from being buried. The device is directly positioned in a mold cavity of a core shooter die, so that core shooting and core manufacturing and continuous core shooting in tailing cleaning are achieved, and as a result, the efficiency in core shooting and core manufacturing of a product is improved, and meanwhile, the working intensity in tailing cleaningis reduced.

Description

technical field [0001] The invention relates to a core-shooting process for casting, in particular to a method for recycling tailings of a cold box core-shooting machine. Background technique [0002] The cold box core-making process has the advantages of high production efficiency, good casting surface quality, high dimensional accuracy, and good sand core collapse, and is widely used in automobiles, internal combustion engines, construction machinery and other industries. The principle of core shooting compaction is to open the compressed air with a certain pressure and capacity in an instant, so that the compressed air is suddenly filled into the sand shooting barrel, thereby forming a high-speed moving sand flow mixed with sand and air, and the sand flow is injected into the core box at high speed. The compaction of the sand core is achieved by the high-speed moving sand flow. In order to ensure that the sand core is well formed, enough resin sand must be reserved in th...

AI Technical Summary

Problems solved by technology

[0003] The invention overcomes the disadvantages of the prior art that the recovery and cleaning of the tailing sand in the sand shooting barrel is difficult and time-consuming during the cold box core shooting process, and provides a tailing sand recovery and utilization device of the cold box core shooter and its use method , the method is by setting the tailing sand recycling device, after the product core shooting is completed, continue to shoot the tailing sand in the sand shooting bucket to the tailing sand recycling device, thereby realizing the automatic cleaning of the tailing sand, avoiding manual sand removal, Thereby improving the efficiency of clearing tailings and reducing the labor load
