摘要： A molding apparatus provided with a transfer capable of transferring a heavy-weight mold clamping device. The molding apparatus that molds a molded product, includes: a mold clamping device clamping a parison extruded from an extruder to obtain a molded body, a transfer rail to support the mold clamping device in a transferable manner, and an electric cylinder to transfer the mold clamping device along the transfer rail. The mold clamping device includes first and second platens for holding a die, and a clamping drive unit for driving the first and second platens closer to or separated from each other, the electric cylinder includes a motor having an output shaft and a feed screw mechanism that converts the rotary motion of the output shaft into a linear motion.
