Powder metallurgy sintering device facilitating die replacement

The utility model discloses a powder metallurgy sintering device convenient to replace a die, which relates to the field of metallurgical processing and comprises a shell, a blind groove is arranged at the top end of the shell, a plurality of support rods are mounted on the left side of the top end of the shell, a fixed seat is mounted at the top end of each support rod, and a lifting plate is slidably sleeved on the outer wall of each support rod. A first hydraulic cylinder is installed at the top end of the fixing base, and the output end of the first hydraulic cylinder downwards extends out of the outer wall of the lifting plate. According to the device, integrated sintering is integrated, a series of machining such as die-casting forming and sintering can be conducted on workpieces, the continuity of the machining process of the workpieces is better guaranteed, meanwhile, the production cost for workpiece conveying is reduced, the die base and the die core can be detached and replaced, and therefore the w
