PROBLEM TO BE SOLVED: To attain the stable operation of an injection molding mold having a slide block and to reduce cost. SOLUTION: A splitting type cavity 13 is formed in a slide core 1 which is integrated with the slide block 11 arranged in a movable mold platen 9. An angular pin 19 fixed to a fixed mold platen 5 penetrates into a slant hole 11c of the slide block 11 with a horizontal clearanceαand a vertical clearance C in a mold-closing state. A locking block 20 is fixed to a fixed mold platen 5, and its slant face 20a presses the slant face 11a of the slide block 11 to close the cavity 13. A headed lock pin 21 is slidably fitted to a stepped through-hole 20b, and is energized so as to project from the lower end of the locking block 20 by a compressed coil spring 22 disposed between a fixed backing plate 6 and the lock pin 21.
