Description

Technical Field

[0001] The utility model relates to the field of core shooting machines, in particular to a core shooting machine with a novel sand feeding and sand shooting mechanism. Background Art

[0002] At present, a Chinese utility model with a bulletin number of CN217370350U discloses a core shooting machine with a novel sand feeding and sand shooting mechanism, including a bottom plate and a core shooting machine body, the core shooting machine body is fixedly connected to the upper left side of the bottom plate, and a sand feeding device is installed above the core shooting machine body. The utility model relates to the field of casting technology, and the core shooting machine with a novel sand feeding and sand shooting mechanism can fix the sand barrel through the vertical plate and the first horizontal plate, and store the core sand through the sand barrel, so as to complete the sand feeding work; the sand pump can guide the core sand in the sand barrel into the sand storage device through the sand conveying pipe, and then shoot the core sand in the sand storage device into the upper core box through the sand shooting device, so as to complete the sand shooting work; the output shaft of the motor can drive the gear rod to rotate through the gear, so that the gear rod drives the second horizontal plate to move through the sleeve, and at the same time, the second horizontal plate is limited by the vertical rod and the rectangular block, so that the second horizontal plate can drive the lower core box to move stably.

[0003] The existing core shooting machine is not convenient for disassembling and assembling the filter. In order to ensure the quality of the sand, a filter is installed in the sand barrel of the general core shooting machine to filter the sand. During use, it needs to be maintained, and the filter is generally fixed to the inner wall of the sand barrel by bolts. When disassembling and assembling, tools are required to disassemble and assemble it. The operation is cumbersome, which increases the workload and reduces the maintenance efficiency. It also does not have a cleaning function. During the use of the core shooting machine, the sand shooter will always add excessive coated sand to the mold, so the excess coated sand needs to be brushed off. Generally, the staff uses a scraper to scrape off the excess sand, which is very troublesome, increases the workload and reduces the work efficiency. In order to solve the above-mentioned problems, we propose a core shooting machine with a new sand feeding and sand shooting mechanism. Utility Model Content
