Core shooting device and operation method of core shooting device

Abstract

The invention discloses a core shooting device and an operation method thereof. The core shooting device combines a sand shooting mechanism and a core shooting mechanism, a driving mechanism is used for realizing sand shooting operation of the sand shooting mechanism and core shooting and core pulling operations of the core shooting mechanism, and the cost of separately arranging a driving mechanism for the core shooting mechanism can be saved; and moreover, the arrangement of the core shooting mechanism and the sand shooting mechanism does not affect each other, the overall structure is simpler, and the operation is convenient.

Description

technical field [0001] The invention relates to the field of casting machinery, in particular to a core shooting device and an operating method of the core shooting device. Background technique [0002] The core shooting device is often used when casting various sand cores. The core shooting device includes a sand shooting mechanism, a core shooting mechanism and a sand core mold. First, the core shooting mechanism cooperates with the sand core mold, and then uses the sand shooting mechanism to shoot sand into the sand core mold. , after the core sand is solidified and formed, the core-shooting mechanism pulls the core at last to complete the core casting; the sand-shooting mechanism first injects the core sand into the sand box, and then injects the core sand into the core mold through the sand-shooting hole at the bottom , but the core sand used by the sand shooting mechanism has a certain viscosity. The traditional sand box is prone to residual wet sand, and the sand outp...

[0002] The core shooting device is often used when casting various sand cores. The core shooting device includes a sand shooting mechanism, a core shooting mechanism and a sand core mold. First, the core shooting mechanism cooperates with the sand core mold, and then uses the sand shooting mechanism to shoot sand into the sand core mold. , after the core sand is solidified and formed, the core-shooting mechanism pulls the core at last to complete the core casting; the sand-shooting mechanism first injects the core sand into the sand box, and then injects the core sand into the core mold through the sand-shooting hole at the bottom , but the core sand used by the sand shooting mechanism has a certain viscosity. The traditional sand box is prone to residual wet sand, and the sand output is not thorough enough, resulting in poor quality of the sand core, and the sand outlet is relatively small, and it is impossible to clean the residual sand from the sand outlet. , can only be cleaned from the sand inlet above the sand box, but the residual sand cannot be completely cleaned from the sand inlet; moreover, the core shooting mechanism and the sand shooting mechanism are two separate structures, which are separately assembled in the The drive mechanism is separately provided on the frame, and the cost is relatively high, and when some sand core molds are equipped with a core shooting mechanism on the side combined with the sand shooting mechanism, the space is limited and it is not easy to assemble and the sand shooting mechanism and the core shooting mechanism are two It is very inconvenient to assemble separately, the structure is cumbersome, and the operation is inconvenient

[0003] In view of this, the designer aimed at the many deficiencies and problems caused by the imperfect structural design of the above-mentioned core shooting device.
