Cold-box core blower

Abstract

The invention provides a cold-box core shooter which comprises a frame, a lower air compression bag, a suspending movable shooting cavity and a suspension body, wherein, the lower air compression bag is arranged at the upper end of the frame, the upper part of the frame is provided with a race which is provided with a moving plate, the shooting cavity and the suspension body are arranged on the moving plate by spring in a suspension manner, either the shooting cavity or the suspension body is connected with a shifting cylinder on the frame, the left and right sides at the lower part of the frame are respectively provided with a mold opening and closing cylinder and a roller table frame, the upper end of the roller table frame is provided with a roller table and a baseplate race, the roller table frames at the two sides are provided with a race span adjusting mechanism, and a core box baseplate is arranged between the baseplate races at the two sides; the bottom of the frame is provided with a mold core lifting cylinder and a bearing plate, and the mold core lifting cylinder is connected with the bearing plate; the rear side of the frame at the bottom part is provided with a core outlet cylinder. The cold-box core shooter has the advantages of reasonable structure, realizing direct addition of sand to the shooting cavity by a sand mill, avoiding wall hanging and caking of wall, improving the qualification rate of the sand core and realizing upward air exhaust of the remaining air in the shooting cavity.

Description

technical field [0001] The invention relates to a cold box core shooter in the casting production process, and belongs to the technical field of core shooters in foundry machinery. Background technique [0002] In the whole process of casting production, some important castings have high requirements for sand cores. Sand cores must not only have sufficient strength, accurate size, and clear outline, but also have good collapsibility. The equipment required for the whole core-making process includes a sand mixer, a core shooter and a triethylamine gas generator. The sand mixer mixes the core sand according to the ratio, and puts the prepared core sand into the cavity of the core shooter. , The core shooter shoots the core sand into the core box to make a sand core, and the function of the triethylamine gas generator is to make the liquid amine into gaseous amine and enter the core box through the blowing mechanism to harden the sand core. The performance of these devices is ...
