Claim 1:
2. The mold clamping device of an injection molding machine according to claim 1, wherein
the mold clamping device further includes a photoelectric detector provided in the half nut,
when a first mold thickness adjustment is performed after power is supplied to the mold clamping device, the control unit moves the mold clamping ram from a rearward limit, stops the mold clamping ram when the photoelectric detector detects that the annular convex parts have reached a position facing teeth of the half nut, and performs the mold clamping, and
when the mold thickness adjustment is performed for a second time and subsequent times after power is supplied to the mold clamping device, the control unit moves the mold clamping ram to the movement position calculated on the basis of the difference value and then performs the mold clamping.
