Description

Die-casting die Technical Field The utility model relates to the field of integrated die casting dies, in particular to an integrated die casting die. Background Referring to fig. 3 and 4, the mating surface 20 between the sliding side mold 2 and the fixed mold 3 of the integrated die casting mold is generally shaped according to the shape of the die casting product, that is, the mating surface 20 is generally a horizontal plane, is located at the upper end of the sliding side mold 2, is located at the outer side of the cavity 5, and is directly connected with the cavity 5. The matching surface 20 is high in machining precision difficulty along with the shape, machining inaccuracy is easy to cause, and the matching clearance between the sliding side die 2 and the fixed die 3 is large, so that the problems of flash and aluminum running are caused. The product flash and the aluminum running are not beneficial to die casting production, the product deburring and polishing workload is large, burn equipment and even safety accidents such as hurting people are caused when the aluminum running is serious. Disclosure of Invention Aiming at the problems, the utility model provides an integrated die-casting die, which avoids the problems of flash and aluminum running caused by overlarge gap between a sliding side die and a fixed die by additionally adding a first matching surface between the sliding side die and the fixed die. The die-casting die comprises a sliding side die, a fixed die and a movable die, wherein a cavity is formed between the sliding side die and the fixed die and between the sliding side die and the movable die, two matching surfaces are arranged between the sliding side die and the fixed die, wherein a first matching surface is positioned on the outer side of the cavity and positioned at the front end of the sliding side die, a second matching surface is positioned on the outer side of the first matching surface and positioned at the upper end of the sliding side die, and the first matching surface and the second matching surface are inclined planes. The inclination angle of the first matching surface is 1.5-5 degrees. The inclination angle of the second matching surface is 3-15 degrees. The sliding side die is fixedly arranged on the sliding seat. The sliding side die is driven by an air cylinder. The utility model has the advantages that the first matching surface is newly added between the sliding side die and the fixed die, the first matching surface is positioned at the outer side of the die cavity and at the front side of the sliding side die, the first matching surface and the second matching surface are both inclined planes, and when the cylinder drives the sliding side die to move towards the front end, the sliding side die and the fixed die can be more attached through the first matching surface and the second matching surface, so that the problems of larger clearance, flash and aluminum leakage of die casting products are avoided. Noun interpretation Integrated die casting ‌ integrated die casting ‌ is an innovative manufacturing process that integrates multiple complex part structures on a white body of an automobile into a single part through a die casting process. Was first proposed by tesla in 2019 and applied to Model Y's back plane production in 2020. According to the technology, a large-scale die casting machine is used for injecting metal liquid into a die to form a final part, so that one-time molding of a plurality of parts is realized. Not only simplifying the manufacturing flow, but also improving the production efficiency and bringing new possibility for the light weight of the automobile industry.
