Multifunctional scraper for casting sand core

Abstract

The invention discloses a multifunctional scraper for a casting sand core. The multifunctional scraper comprises a cutter body and a cutter handle, wherein the cutter handle is a main body support component of the multifunctional scraper for the casting sand core; a guide groove is formed inside the cutter handle; a cutter body is arranged inside the guide groove; a push block is arranged on the cutter body; the push block is used for fixing the cutter body and used for driving the cutter body to slide inside the cutter handle; the tip of the cutter body is long and thin, thus being convenient for cleaning burrs in gaps; saw-tooth patterns are formed in the middle of one of the blade surfaces of the cutter body, thus being convenient for cleaning sand filling holes and fins; arc-shaped grooves of different models are formed in the middle of another blade surface, thus being convenient for cleaning the sand core with an arc-shaped structure; a temperature sensation device is arranged at the tail end of the cutter handle, thus being convenient for measuring the temperature of the sand core, and avoiding scalding. The multifunctional scraper has the beneficial effects that the structure is simple and reasonable, use requirements of sand cores of different models can be met in application, the scraper does not need to be replaced alternatively, the using effect is good, and the working efficiency can be improved.

Description

technical field [0001] The invention relates to the field of smelting alloy casting, in particular to a multifunctional scraper for casting sand cores. Background technique [0002] Casting refers to the processing method of melting solid metal into liquid and pouring it into a mold of a specific shape, and waiting for it to solidify and form. Ordinary sand casting uses the sand core as the mold material. The shape of the sand core is the key. The precision of the casting and the economic effect of the entire production process mainly depend on this process. After the sand core is taken out of the mold, there are sand injection holes, burrs and drape seams, etc., which need to be further cleaned. In actual operation, it is scraped off with a scraper. Due to the variety of casting products, a variety of different types of scrapers are required. During work, the staff will replace them back and forth according to specific needs, which is inconvenient to use and reduces work e...
