Core shooter for casting

Abstract

The invention discloses a core shooter for casting, and belongs to the technical field of core shooter equipment. The core shooter for casting comprises a rack, a hopper, a first cleaning part, a sandshooting barrel and a second cleaning part. The rack comprises a bearing plate, and four groups of supporting columns are vertically welded at four corners of the lower surface of the bearing plate;the hopper is formed on the upper surface of the bearing plate and is in a funnel shape with openings at the upper and lower parts; the first cleaning part is formed in the hopper and comprises a rotating rod, one end of the rotating rod is rotationally connected with the inner wall of one side of the hopper through a shaft seat, the other end of the rotating rod penetrates out of the hopper, a driving motor is coaxially arranged at the penetrating-out end, and a supporting seat is arranged below the driving motor; the sand shooting barrel comprises a mounting base and is formed on the lower surface of the bearing plate; and the second cleaning part is formed on the supporting column close to one side of the sand shooting barrel and comprises a cleaning head, the cleaning head is formed ina cavity of the sand shooting barrel, connecting rods in a through hole set A and a through hole set B drive a cleaning plate to conduct cleaning in the hopper, and the cleaning effect is enhanced.

Description

technical field [0001] The invention belongs to the technical field of core shooter equipment, in particular to a core shooter for casting. Background technique [0002] The core shooting machine is made of coated sand, which is suitable for both hot core boxes and cold core boxes. The middle fixing frame can install the fixed mold on both sides, and the left and right open and close the mold (equivalent to a double mold frame). The core shooting machine is widely used in the foundry industry. The principle is to inject the core sand mixture with liquid or solid thermosetting resin as the binder into the heated core box, and the sand core is preheated and hardened to a certain thickness (about 5-10mm) in the core box. Take it out to form a high-quality sand core product with a smooth surface and accurate dimensions; the core shooter has been widely used in recent years, and the use of the core shooter can save high wages for molding workers. Because it is multi-box stacked...

Problems solved by technology

[0004] However, when the above-mentioned core shooting machine is shut down for a long time, it is necessary to clean the remaining sand in the sand bucket and the sand shooting cylinder. In the prior art, the sand blocks are generally removed manually, which is inconvenient to use and the cleaning effect is poor.
