る。(Prior Art) A conventional vertical press has a die mounting fixture plate on the upper part and a base disc part on the lower part, and four tie bars connecting the die mounting fixture plate and the base plate, and a die. A mold mounting movable plate that is located between the mounting and fixing plate and the base plate and moves up and down on the tie bar,
It is composed of a hydraulic cylinder that raises and lowers the movable die mounting plate. The movable die mounting plate moves up and down by a hydraulic cylinder on a tie bar, and the movable die mounting plate is mounted on a fixed die mounted on the bottom surface of the stationary die mounting plate. The movable mold attached to the upper surface of the board is pressed and clamped. A tie bar bush is inserted in the tie bar sliding part of the mold mounting movable plate,
The movable plate on which the mold is attached can be smoothly moved up and down.
When molding the thermosetting resin, when the temperature of the solid mold and the movable mold is raised, the mold mounting fixed plate and the mold mounting movable plate are thermally expanded, and the four tie bars open slightly at the top. And a tie bar bush is provided with a gap. If this gap is made smaller, the mechanical accuracy will be improved, but when the movable plate on which the mold is mounted moves up and down, a kinking (partially strong contact) occurs, the sliding resistance becomes extremely large, and low-pressure mold clamping becomes impossible. Therefore, this gap is indispensable.

Detected the foreign matter that was caught on the die mating surface. That is, low pressure oil is injected into the lifting hydraulic cylinder of the movable die mounting plate, the movable die mounting plate is raised, the upper surface of the movable die is pressed against the bottom surface of the fixed die with low pressure, and the low pressure die clamping is performed. I do. This low-pressure tightening is a mold clamping that does not damage the mating surfaces of the molds even if foreign matter is caught between the mating surfaces of both molds. The sensor approaches the operating position and gives a signal that there is no foreign matter. Also, if a foreign object is caught, the sensor cannot operate because it cannot reach the operating position. Therefore, a signal is issued to inform that the foreign matter is caught in the die mating surface.
