PROBLEM TO BE SOLVED: To provide a mold for molding which is capable of reducing the number of parts, making the mold small-sized, lightweight, reducing cost and is provided with a clamping mechanism. SOLUTION: The mold for molding is provided with a clamping mechanism for holding the clamp of the mold so that an upper mold 2 and a lower mold 1 are not opened at the time of clamping both molds and for releasing holding the clamp. The mold clamping mechanism comprises three structural components of a guide pin 3 fixed to the upper mold, a clamp block 4 built-in inside the lower mold to be rotated and a block rotation part 5 which engages to the clamp block by inserting from lower part of the lower mold, and is made to rotate the clamp block. The tip of the guide pin is inserted in the clamp block in closing the mold and the mold clamping is carried out by rotating the clamp block by the block rotation part and engaging the guide pin with the clamp block.
