Positioning structure for inserts in die

The utility model discloses a positioning structure for inserts in a die. Each insert body is formed by connecting a function part and a fixed connecting part, wherein the width of the function part is smaller than that of the fixed connecting part, a pressing protruding block is arranged at the lower end of the fixed connecting part, and the pressing protruding block is arranged in the length direction of the fixed connecting part. According to the pressing protruding blocks of the inserts, after the inserts are placed in the die in a matched mode, several pressing positioning columns with the same height correspond to the position above the pressing protruding block of each insert, the lower ends of the pressing positioning columns tightly abut against the corresponding pressing protruding block, and then the corresponding insert can be flatly pressed. When liquid molten metal is injected into a cavity in a pressed mode, although the molten metal generates buoyancy effect and large impact effect on the inse
