The side of the scraping block 6 away from the telescopic groove 5 and close to the mold 3 is provided with a rounded corner.

[0020] During operation, the mold 3 is installed inside the extrusion cylinder 1, and then the aluminum alloy raw material is placed along the extrusion groove 2. At this time, the hydraulic rod 4 is inserted into one end of the extrusion groove 2. The rounded corner of the scraping block 6 will first contact the edge of the extrusion groove 2. At this time, the scraping block 6 will squeeze the spring 7 to contract and enter the telescopic groove 5. When the scraping block 6 enters the extrusion groove 2, the spring 7 will push the scraping block 6 to fit with the inner wall of the extrusion groove 2. After extrusion is completed, the hydraulic rod 4 is pulled out. The flat surface of the scraping block 6 will slide along the inner wall of the extrusion groove 2 to scrape off the aluminum alloy raw material remaining on the inner wall of the extrusion groove 2, achieving the effect of quickly cleaning the inner wall of the extrusion groove 2, solving the problem that some aluminum alloy raw materials adhere to the inside of the extrusion groove 2, and the subsequent raw material addition will push out the residues adhering to the inner wall of the extrusion groove 2, resulting in defective products, and improving production efficiency.
