った。Problems to be Solved by the Invention The above-mentioned blast cleaning method (hereinafter referred to as "grinding" according to the terminology used in the field) including "shot blasting" and "sand blasting" is a method of cleaning iron particles and glass beads. By spraying such fine particles onto an object (hereinafter referred to as "object to be polished"), surface treatments such as sand removal and scale removal can be suitably performed. However, after polishing, the surface of the object to be polished contains a mixture of fine particles used in the series of polishing operations and fine particles that have fallen off from the object due to the impact of time. Attach to. Therefore, as post-processing, it is necessary to wipe off the deposits and wash with water, but this has traditionally been a laborious and labor-intensive task, and the working environment is also poor as a large amount of dust is handled. there were.

促進するために、塗型（一種の離型剤）が塗布される。Furthermore, there are also workplaces where the entire work of scraping off the surface of the object with a wire brush or the like and subsequently cleaning up any deposits is carried out manually, without using abrasive methods such as the above-mentioned plastic cleaning method. Some exist. For example, in a split mold consisting of an upper mold and a lower mold used in centrifugal casting, a coating (a type of mold release agent) is applied to the inner surface of the cavity of each mold to promote release of the cast product. applied.

請となっていた。In addition, if the casting object is a hollow molded product such as a ball valve,
A core made of solidified sand is installed and used in a one-piece mold. Centrifugal casting is performed using such a mold, and after the mold is divided and the cast products are taken out, the inner surface of the cavity of each mold is cleaned for reuse. At this time, since there is residual core sand remaining on the inner surface of the cavity, this is vacuumed up using a vacuum cleaner, and the coating mold that is partially peeled off on the inner surface of the cavity is scraped off with a wire brush, etc. A series of operations are required to remove the mold powder and vacuum suction the resulting coating powder, but as this has traditionally relied on manual labor, there has been a pressing need for improvements in terms of work efficiency and working environment.

離される。Next, the shutter 13a of the entrance 11 is closed (the opening 10 provided in the partition wall 7 is closed by the shutter 13b), and when the cleaning chamber 8 is sealed, cleaning is started. That is, a mixed jet of glass beads and high-pressure air is blown from the nozzle 16 onto the inner surface of the cavity 4a directed upward of the lower mold 4. At this time, the nozzle 16 swings within the cleaning chamber 8 by the swinging mechanism described in connection with FIG. Further, horizontal rotation of the rotary table 15 is started in synchronization with the start of the cleaning, and together with the rocking of the nozzle 16, the spraying of the mixed jet to the cavity 4a is made uniform. In addition, a large amount of grinding debris (core sand, flaked powder from the coating mold, and other powders) is generated in the cleaning chamber 8 due to the above-mentioned cleaning, and it is mixed with the glass beads and dances around in the cleaning chamber 8. However,
This is collected together with high pressure air into the lower hopper 22,
Furthermore, it is separated into fumes and abrasive debris in the cyclone chamber 24 described above.

It is transferred to the spraying room 9. At this time, the surface of the lower die 4 which has been ground is covered with grinding debris consisting of the core sand, flaked powder of the coating die, and other dust. In addition, the entrance 11 of the cleaning chamber 8 is opened synchronously, and the next upper die 3 that has been waiting to be polished on the upstream side is carried into the cleaning chamber 8.

The shutter 13b of the opening 1o is closed (the outlet 12 is closed by the shutter 13c), and high-pressure air is injected from the nozzle 17 arranged indoors toward the lower mold 4, thereby causing the cavity inner surface 4a of the lower mold 4 to Other cleaning debris and dust attached to the outer peripheral surface are effectively blown off. The blown-off abrasive debris and dust are collected together with high-pressure air into the hopper 23 below, and further separated into fumes and abrasive debris in the cyclone chamber 24. Note that when high-pressure air is injected from the nozzle 17 toward the lower die 4 in the air blowing chamber 9, the upper die 3 carried into the upstream grinding chamber 8 is also cleaned at the same time, so that both The nozzles 16 and 17 are synchronously urged to swing by the swing mechanism.

る。When the cleaning and air blowing in the cleaning chamber 8 and the air blowing chamber 9 are completed in this way, the shutters 13 provided at each opening are opened, and the molds that have undergone each operation are directed downstream. The lower mold 4 that has been sent out, that is, the work in the air blowing chamber 9 has been completed, is conveyed toward the conveyor 1c located in one area C, where it is coated with a mold coating as a mold release agent, for example. Furthermore, the upper die 3 that has been cleaned in the cleaning chamber 8 is then transported to the air blowing chamber 9, and in the now empty cleaning chamber 8, there is another mold waiting to be cleaned on the upstream side. The lower mold 4 is carried in.
