Description

Technical Field

[0001] The utility model relates to the technical field of core shooting, in particular to a residual sand scraping device for a mold. Background Art

[0002] Core shooters are widely used in the foundry industry. The cores made by core shooters are accurate in size and smooth in surface. The working principle of the core shooter is to shoot the core sand mixture with liquid or solid thermosetting resin as binder into the heated core box. The sand core is preheated in the core box and quickly hardened to a certain thickness (about 5-10mm) and then taken out to form a high-quality sand core product with smooth surface and accurate size. After the sand shooter and the mold are separated, a layer of residual sand will form on the surface of the mold to cover the surface of the mold. In order to facilitate the next casting and save the cost of coated sand, the sand layer on the surface of the mold needs to be scraped off. The current scraping is manual, which is time-consuming and labor-intensive.

[0003] To solve this problem, relevant designers have designed a sand scraping device as shown in CN109014072A. However, this sand scraping device can only scrape off the residual sand, and the scraped residual sand lacks a collection device, which is difficult to clean and collect after scraping.
