Abstract

The invention relates to the technical field of core making machines, and discloses sand-shooting sealing auxiliary equipment for core sand filling equipment of a core making machine. The sand-shooting sealing auxiliary equipment comprises a sand mold cavity, wherein a forming cavity is formed in the sand mold cavity, and heating plates are fixedly mounted at the left end and the right end of theforming cavity; and fixing frames are fixedly mounted in the sand mold cavity and on the opposite surfaces of the heating plates. According to the sand-shooting sealing auxiliary equipment for the core sand filling equipment of the core making machine, when a sand shooting gun gets close to the sand mold cavity, moving rods are matched to drive sliding rods to move downwards in the sand mold cavity, on one hand, connecting rods are driven to move, the connecting rods drive butt joint plates to move upwards and be lifted upwards to be matched with the sand shooting gun, and therefore the sealing effect in the sand-shooting process is improved; and on the other hand, extrusion rods are matched to drive sliding plates to slide in the fixing frames, in cooperation with the effect of air outletbags, dust on the butt joint plates can be blown away when the sand shooting gun is separated from the sand mold cavity, and therefore the effect of automatic cleaning is achieved.

Description

technical field

[0001] The invention relates to the technical field of core-making machines, in particular to a sand-shooting and airtight auxiliary equipment for core-making core sand filling equipment. Background technique

[0002] The core making machine is the collective name of the core shooting machine and the shell core machine. It is the equipment for the coated sand shell core made by the hot core box process. It is hardened in the box to form a core with a smooth surface and precise dimensions. The core making machine is widely used in the foundry machinery industry.

[0003] However, during the sand shooting process of the current core making machine, sand and stones are prone to leak at the joint between the sand shooting port and the sand core cavity, causing sand and stones to splash onto the core making machine and affecting its normal operation. Manual cleaning of sand and gravel reduces work efficiency. If uncleaned sand and gravel remain on the end face of...
