Compacting device for casting

Abstract

The invention discloses a compacting device for casting, and relates to the field of moulding sand casting. The device comprises a compacting plate, a shoveling handle and a connecting rod, wherein the compacting plate is in a shape of disc; a plurality of circumferentially-distributed bases are arranged on the compacting plate; one end of a spring is arranged on each base, and the other end of each spring is provided with a shifting seat; a first end head is arranged at one end of the shoveling handle, and a second end head is arranged at the other end of the shoveling handle; a screw hole provided with inner threads is formed in the second end head; the first end head is in thread connection with the compacting plate; outer threads which fit the inner threads in the second end head are formed in one end of the connecting rod; the connecting rod is in thread connection with the second end head through the outer threads; a U-shaped fixing seat is fixedly connected to the other end of the connecting rod; a disc is hinged with the fixing seat; a pickaxe head is fixed to the disc. The device is simple in structure; the shoveling handle is detachably connected to the connecting rod; one end of the connecting rod can realize the pickaxe head function through the rotatable pickaxe head; in addition, the compacting plate can be quickly and effectively cleaned, so that the multifunctional property of the compacting device is realized.

Description

technical field [0001] The invention relates to the field of sand casting, in particular to a compacting device for sand casting. Background technique [0002] Sand casting is a casting method for producing castings in sand molds. Because the molding materials used in sand casting are cheap and easy to obtain, and the casting molds are easy to manufacture, it can adapt to single-piece production, batch production and mass production of castings. For a long time, it has been It is the basic process in casting production. An essential process in sand casting is to compact the molding sand in the sand box, because during the manufacturing process, when the pattern is placed in the sand to make a mold, the casting will be damaged due to insufficient filling or compaction of the molding sand. Or the uneven surface will affect the quality requirements of the castings, and there are certain deficiencies. Therefore, the compaction device for sand casting is an indispensable tool fo...
