摘要： Provided is a mold clamping device that can simplify the component count or structure by including a mold thickness adjustment mechanism that reduces the load on a power source, is easily maintained, and has high design flexibility. Also provided is a mold clamping device that can set a long distance (daylight) between molds without having to upsize the entire mold clamping device and can simplify the component count or structure.
A mold clamping device for split molds includes a first platen, a second platen, a pressure receiving platen, and a mold thickness adjustment mechanism disposed on the pressure receiving platen. At least one of the first platen and the second platen is able to move back and forth so as to approach or depart from the other. The pressure receiving platen is located on a side remote from the first platen, of the second platen. The mold thickness adjustment mechanism includes a rod-shaped rotation member, a power source configured to rotate the rotation member around a rotation axis of the rotation member, the rotation axis being parallel to a longitudinal direction of the rotation member, and a pair of converters configured to convert rotation direction of the rotation member into a movement direction of the second platen. A mold clamping device for split molds includes polygonal first and second platens, a pressure receiving platen, and a toggle mechanism. At least one of the first platen and the second platen is able to move back and forth so as to approach or depart from the other. The pressure receiving platen is located on a side remote from the first platen, of the second platen. The toggle mechanism is disposed between the second platen and the pressure receiving platen and on a diagonal line of the second platen and configured to cause the first and second platens to approach or depart from each other.
