A kind of anti-solidification blockage equipment for sandblasting port for core making machine

Abstract

The invention provides a device for preventing solidification and blockage of a sandblasting port for a core making machine. A metal sheet is arranged inside the fixing plate and on the lower side of the chute, and the rear end of the driving gear is connected to the rear part of the support rod with an auxiliary The auxiliary wheel is connected with the turntable through the belt, and the middle part of the rope is connected with the guide plate in the chute. A toothed plate is attached. The drive gear drives the toothed plate to move to the outside, and the guide column drives the cleaning device to approach the sandblasting port of the sandblasting device, passing the horizontal limit of the chute, so as to ensure that the cleaning rod on the cleaning device and the sandblasting port of the sandblasting device are connected horizontally. , and the guide column is in contact with the metal sheet, so as to automatically control the internal drive of the cleaning device. This structure achieves automatic cleaning of the sandblasting port of the sandblasting device, thereby preventing part of the core sand against the wall of the sandblasting hole from being heated and solidifying, gradually Block the sand shot channel.

Description

technical field [0001] The invention belongs to the technical field of core-making machines, and in particular relates to a device for preventing solidification and clogging of a sandblasting port for a core-making machine. Background technique [0002] The core making machine is the general name of the core shooting machine and the shell core machine. Its working process is completed at the same time as sand filling and compaction, and it is immediately hardened in a hot core box, reducing labor intensity, flexible and light in operation, easy to master, using electric heating, temperature can be automatically controlled, and the working place is easy to keep clean. The mechanization and automation of the core making process create conditions. Sand cores for casting can be produced in a cycle of only ten to several tens of seconds. [0003] In the existing core making machine, when the sand shooting hopper presses the mold, the heat of the mold will also be conducted to t...

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.
