Claims

[Claims for Utility Model Registration] First, second, and third mold elements are sequentially arranged so as to be able to approach and separate from each other so that they can be opened and closed, and a cam plate is connected to the first mold element. Said second
, attached to extend toward a third mold element, a locking piece is provided on the second mold element, and a locking plate is swingably supported on the third mold element, The locking plate locks the second mold element when the second mold element and the third mold element are in a closed state.
The mold element is set to be pressed by the cam plate and locked by the locking piece when it approaches the first mold element, and the locking plate is attached to the third mold element. In the mold opening/closing device, the mold opening/closing device is provided with a biasing means that biases the locking piece in a direction to release the locking piece, wherein the locking piece is configured to move the locking plate based on a displacement movement of the third mold element. is held by the second mold element so as to be movable forward and backward with respect to the displacement movement area of the locking plate, and is urged by a spring member so as to face the displacement movement area of the locking plate, and the locking piece and the locking plate are At least one of the locking plates is formed with a tapered cam surface that converts a force based on the displacement movement of the locking plate into a force in the withdrawal direction of the locking piece. Mold opening/closing device.
