PROBLEM TO BE SOLVED: To process a mold efficiently with a tool of a short axial length by preventing the interference of a tool holder with a mold main body in spite of the short axial length of the tool when the tool is slanted outside in relation to a seal surface to process the corner parts of the seal surface and product molding surface of a male mold 1 in an injection molding mold in which in the male mold 1 and a female mold 2, product molding surfaces 11, 12 facing a cavity 3, seal surfaces 12, 22 around the product molding surfaces for sealing the cavity, and pressure receiving surfaces 14, 24 which adjoin the outsides of the seal surfaces through step surfaces 13, 23 and receive mold clamping force are formed. SOLUTION: The pressure receiving surfaces 14, 24 of the male mold 1 and the female mold 2 are offset in the mold opening direction in relation to the seal surfaces 12, 22 of the molds 1, 2 so that the step surface 13 of the male mold 1 enter the inside of the step surface 23 of the female mold 2. No protruded part exists on the outside of the seal surface 12 of the male mold 1, and the tool can be slanted outside in relation to the seal surface 12 without interference with the protruded part in spite of the short axial length of the tool.
