Abstract: A molding device includes: a lower mold that supports a workpiece containing a thermoplastic resin and that is heated to a first predetermined temperature; an upper mold that is opposed to the lower mold, that presses the workpiece, and that is heated to a second predetermined temperature; a transferer that moves the lower mold and the upper mold relative to each other in a transfer direction of the workpiece; and control circuitry. The lower mold includes temperature-controlled regions adjacent to one another in the transfer direction, the temperature-controlled regions including a first lower mold temperature-controlled region and a second lower mold temperature-controlled region having a temperature lower than a temperature of the first lower mold temperature-controlled region. The control circuitry changes proportions of the first and second lower mold temperature-controlled regions in the lower mold as a function of a relative position between the upper and lower molds.

Abstract: A temperature adjustment mold capable of performing local temperature adjustment in an axial direction from the inside of a preform while restricting shrinkage and deformation of the preform, for adjusting a temperature of an injection-molded bottomed resin-made preform includes a rod portion inserted into the preform and extending in the axial direction of the preform. The rod portion includes an annular projection portion that protrudes in a radial direction of the rod portion and contacts an inner peripheral surface of the preform. The rod portion contacts a bottom portion of the preform to restrict shrinkage in the axial direction of the preform. The projection portion restricts shrinkage in a radial direction of the preform, conducts heat between the rod portion and the preform, and adjusts a temperature at a predetermined part in an axial direction of the preform.
