Sand blasting opening curing blockage prevention equipment for core making machine

Abstract

The invention provides sand blasting opening curing blockage prevention equipment for a core making machine. A metal sheet is arranged in a fixing plate and located on the lower side of a sliding groove, an auxiliary wheel is connected to the rear end of a driving gear and located on the rear portion of a supporting rod, the auxiliary wheel is connected with a rotating disc through a belt, a guide plate is connected to the middle of a rope and located in the sliding groove, guide columns corresponding to the sliding grooves are arranged on the lower portion of the guide plate, the front ends of the guide columns are connected with a cleaning device, and the upper portion of the driving gear is connected with a toothed plate. The driving gear drives the toothed plate to move towards the outer side, the guide columns drive the cleaning device to be close to a sand blasting opening of a sand blasting device, through horizontal limiting of the sliding groove, it is guaranteed that a cleaning rod on the cleaning device is horizontally connected with the sand blasting opening of the sand blasting device in an inserted mode, and through contact between the guide column and the metal sheet, internal driving of the cleaning device is automatically controlled, by means of the structure, the sand blasting opening of the sand blasting device can be automatically cleaned, and therefore part of core sand close to the wall of a sand blasting hole can be prevented from being heated to be cured to gradually block a sand blasting channel.

Description

technical field [0001] The invention belongs to the technical field of core making machines, and in particular relates to an anti-solidification blockage device for a sandblasting port of a core making machine. 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 that uses the hot core box process to make the coated sand shell core. Its working process is completed by sand filling and compaction at the same time, and it is immediately hardened in the hot core box, which reduces labor intensity, is flexible and light in operation, and is easy to master. It adopts electric heating, the temperature can be automatically controlled, and the working place is easy to keep clean. The mechanization and automation of the core-making process creates conditions. Sand cores for casting can be produced in only ten to tens of seconds in one cycle.

AI Technical Summary

Problems solved by technology

[0003] In the existing core-making machine, when the sand-shooting bucket presses the mold, the heat of the mold will also be transferred to the surface where the sand-shooting bucket and the mold are in contact. The core sand on the wall will solidify when heated, and will stick to the wall of the shot hole at the same time. Over time, the sticky sand on the wall of the shot hole will become thicker, which will make the shot hole smaller and gradually block the shot channel. It is necessary to stop the machine and clean the sand shooting holes one by one. Some sand shooting buckets are also cooled by water, but there will still be residual sand adhered. The sand shooting holes of the sand shooting bucket must be cleaned.
