Abstract
A molding apparatus for glass molded product includes a mold, a press shaft and a release device. The release device includes a release member, a push bar, and a release action mechanism. The release member has a lower end surface to face an outer peripheral portion of a molding surface of the lower die of the mold. The push bar adjusts a downward pressure given to the release member. The release action mechanism is provided to hold an upper portion of the push bar movably along a shaft direction of the press shaft. The release action mechanism moves the push bar and the release member downward along the shaft direction to release a glass material and the upper die of the mold when the upper die and the lower die are separated after the glass material has been pressed between the upper die and the lower die.
