Description

Technical Field

[0001] The utility model relates to the technical field of die casting production, in particular to a trimming die for aluminum alloy die castings. Background Art

[0002] A die-casting machine is a machine used for pressure casting, including a hot press chamber and a cold press chamber, which are later divided into two types: vertical and horizontal. The die-casting machine hydraulically injects molten metal into a mold under pressure for cooling and forming. After the mold is opened, a solid metal casting can be obtained. It was originally used for die-casting lead type. With the progress of science and technology and industrial production, especially with the development of industries such as automobiles, motorcycles, and household appliances, die-casting technology has achieved extremely rapid development. The feed port of the die-casting produced by the die-casting machine will produce columnar waste, which needs to be cut off using a trimming die. In the die-casting of the die-casting, not only will waste accumulate at the feed port, but also flash will be generated. Therefore, when trimming, the edge of the die-casting needs to be cut in all directions. The existing trimming molds and equipment often use a waste collection structure for cutting at positions such as the feed port, such as setting an inclined guide groove to guide the cut parts into the collection groove below, but the trimming in other directions will be deposited on the workbench and difficult to clean.
