    摘要: There is provided a mold clamping apparatus that can prevent a molding material from spouting from a split surface of a mold even if in-cavity resin pressure causes offset of a mold opening force, and can extend the life of the mold. The mold clamping apparatus includes a control device that estimates a mold opening force by mold internal pressure for molding with mold internal pressure being asymmetrical with respect to a center of a mold block, determines a mold clamping hydraulic value applied to each tie bar correspondingly to the estimated mold opening force, and distributes hydraulic pressure supplied to each tie bar so that the determined mold clamping hydraulic value is reached.

    摘要: A heat medium heating device 10 includes an inner case main body 21 having a flow path of a heat medium formed inside, an outer case main body 31 arranged on an outer peripheral side of the inner case main body 21 and having a flow path of the heat medium formed outside, and a PTC heater 40 held as being interposed between the inner case main body 21 and the outer case main body 31. The inner case main body 21 and the outer case main body 31 each may have a circular outer shape or a rectangular outer shape. Also, the inner case main body 21 and the outer case main body 31 are preferably provided with fins 24 and 34, respectively, facing the flow path of the heat medium.
