PURPOSE:To accurately mold a parison of high quality by clamping molds for hollow molding the parison provided at first and second mold mounting plates by a motor and a rotary screw. CONSTITUTION:Molds 10 provided at first and second mold mounting plates 4, 8 to hollow mold a parison 2a provided at the plates 4, 8 are clamped through mold clamping means 20. In this case, the means 20 clamps the molds by a front plate 3 provided at the plate 4, a rear plate 6 connected to the plate 3 via a tie bar 11 and a motor 33 provided at the plate 6. The motor 33 has a nut 31 engaged with a connected rotary screw 30 and provided at the plate 8. The molds 10 are clamped by the rotation of the motor 33.
