Title:
MOLDING DEVICE AND MOLDING METHOD
Document Type and Number:
WIPO Patent Application WO/2018/008696
Kind Code:
A1
Abstract:
Provided is a molding device that molds a substance to be molded by closing a pair of molds. The molding device comprises: a slide to which one mold among the pair of molds is attached and can advance and retreat in an advancing/retreating direction that is a direction toward the other mold; a mold clamping force generating unit that has a piston that can move in the advancing/retreating direction as a result of being supplied with hydraulic oil and that generates a mold clamping force; a slide driving unit that causes the slide to advance or retreat in the advancing/retreating direction; and a mold clamping force transmitting unit that transmits the mold clamping force from the mold clamping force generating unit to the slide. The slide has a hole through which the piston can pass. The mold clamping force transmitting unit has a force transmitting body and a force transmitting body driving unit. The force transmitting body can move between a first position at which the force transmitting body covers the hole and prevents the piston from entering the hole, and a second position at which the force transmitting body is withdrawn from the first position and the piston is allowed to enter the hole. The force transmitting body transmits the mold clamping force from the piston to the slide when positioned at the first position. The force transmitting body driving unit causes the force transmitting body to move.
