The scraping knife comprises a housing and a scraping knife body, wherein a concave port is formed in one end ofthe housing; a clamping buckle is fixedly connected to one side of the outer surface of the housing; a top plate is arranged at the top part of a chute; two ends of the bottom part of the top plate are fixedly connected to fixing blocks; one end of a first telescoping rod is fixedly connected to the center of the bottom part of the top plate, and first sliding blocks are arranged on two sides ofthe other end of the first telescoping rod; first sliding grooves are formed in two inner sides of a second telescoping rod; and the first sliding blocks are arranged in the first sliding grooves. Thescraping knife is reasonable in design, convenient to use, and applicable to cleaning of the inner cavity of the plastic die; through the cooperative operation of a fixing belt and the clamping buckle and the cooperation of an adhering head and a soft pad, the elasticity of the fixing belt can be adjusted, and as a result, the problem that hands are sore after holding for a long time can be effectively prevented, and the safety is improved; and the scraping knife is simple, convenient, and suitable for wide popularization.

Description

technical field [0001] The invention relates to the technical field of plastic molds, in particular to a scraper for cleaning the inner cavity of a plastic mold. Background technique [0002] The scraper is the main tool for scraping, and T12A high carbon tool steel is generally used to make the scraper. According to the scraping surface of the workpiece, scrapers can be divided into three categories: flat scrapers, triangular scrapers and crescent-shaped scrapers. The flat scraper is mainly used to scrape planes, such as flat plates, flat rails, workbenches, etc. It can also be used to scrape outer curved surfaces. The triangular scraper is one of the commonly used tools for scraping bearing bushes. The crescent-shaped scraper is mainly used to scrape inner curved surfaces, such as movable Bearing inner hole, etc. Although the traditional scraper is easy to use and has high mobility, its biggest disadvantage is that when the user holds the handle, the fingers must be tight...
