To eliminate an unstable phenomenon such as vibration or noise at the time of control of deceleration or stopping to enhance durability and to reduce cycle loss at the same time to enhance production efficiency.

In a control method for a toggle link type mold clamping device 1c performing mold on-off operation and mold clamping by arranging a toggle link mechanism L between a pressure receiving plate 2 and a mold clamping plate 3 and moving the crosshead Lh of the toggle link machanism L by the drive part 4 provided to the pressure receiving plate 2 so as to allow the same to advance and retreat, the mold clamping plate 3 is controlled so that the load speed As of the mold clamping plate 3, until the mold clamping plate 3 is decelerated or stopped after moved at a low speed Vs, becomes lower than the load speed Af of the mold clamping plate 3 until the mold clamping plate 3 is decelerated or stopped after moved at a high speed Vf.
