Description of the Related Art In recent press working, highly precise working and automation are required, and a mold is provided with a cushion pin that is operated by air pressure, or an ejector for pneumatically discharging a processed work out of the mold is built in. The mold is equipped with pneumatic equipment. Further, in order to respond to various tastes of recent consumers, a production method of a small amount of a wide variety of products is adopted, and in press working, there is a mold for each product, and the press machine is frequently replaced with a mold for processing. Since this type of setup change is repeated many times, press productivity is reduced unless it is done quickly in order to increase production efficiency. In recent years of press work that requires many setup changes, it is important to perform the setup changes in a short time, and among them, how to quickly and accurately connect the pneumatic equipment of the mold and the air source is important.

間違いの場合、空気圧の漏れが生じる。A supply valve chamber 216 is provided above the piston 213.
And a sliding cylinder 218 is projected upward in the supply valve chamber 216 so as to be linearly continuous with the supply passage 217.
The lower shaft portion 220 of the supply valve 219 is slidably fitted into the sliding cylinder 218, and fitted externally to the sliding cylinder 218 so that the main body member 221 of the supply valve 219 and the base end side of the sliding cylinder 218 are connected to each other. The supply valve 219 is biased upward by an elastic coil spring 222 that is contracted between the two. The supply valve 219 energized by the coil spring 222 has a seating surface 22 formed as a slope on the upper part of the supply valve chamber 216.
Abut on 3. The supply flow passage 217 communicates with the supply valve chamber 216 through a hole 224 formed in the partition wall of the sliding cylinder 218 on the proximal end side. In order to move the supply valve 219, a flow path 235 for moving the supply valve 219 communicating with the piston chamber 211 outside the supply flow path 217.
Is provided. A state in which neither the moving passage 235 nor the supply passage 217 is operated with air pressure is the state shown in FIG. Here, the piston 213 is pushed downward and held by the coil spring 215. The state shown in FIG. 6 is obtained by activating the air pressure in the supply channel 217 after activating the air pressure in the moving channel 235. When air pressure is applied to the moving flow path 235, the piston 213 rises and the supply valve 219 is pushed down by the operating member 205 to open the valve. After that, when air pressure is applied to the supply passage 217, the air pressure is supplied to the mold 203. The state where air pressure is supplied only to the supply channel 217,
This is the state shown in FIG. When air pressure is applied to the supply passage 217, a pressure is generated in the piston 213, and when the pressure becomes larger than the biasing force of the coil spring 215, the piston 21
3 is pushed up, hits the lower surface of the mold 203, the supply valve 219 opens, and air pressure leaks. In this way, in the case of an operation error such that the air pressure is not supplied to the supply flow path 217 after the air pressure is supplied to the moving flow path 235 and the air pressure is supplied to the supply flow path 217 alone, the air pressure leaks.

に相当する分だけ合わせ面102 上に突出する。As described above, there is an automatic connecting device between the pneumatic equipment of the mold and the air source, but in either case, there is a protruding portion 107 on the mating surface 102 of the bolster 101. It also projects above the bolster in Jitsuko Sho 53-40525. Temporarily connect the supply valve 105 to the mating surface 102 of the bolster 101.
Even if it is located lower, the connection port on the mold side, that is, the head 112, projects above the mating surface 102 by at least the amount corresponding to the lift for opening the supply valve 105.

望ましい。Since the mold is a metal block body and is heavy and heavy, when it is set at a predetermined position of the bolster 101, it slides on the mating surface 102 of the bolster 101 and moves. If there is a protruding portion 107 on the bolster 101, sliding the mold 110 causes the mold 110 to hit the protruding portion 107 and damage the protruding portion 107. To avoid damage to the protruding part 107, lift the heavy mold 110 so that the actuating member 111 is located directly above the supply valve 105, and then move the mold 110 to the mating surface.
102 The work efficiency must be lowered because it must be lowered and the work must be done with caution. Further, it is desirable that the operation sequence is not limited, in which the air pressure is first supplied to the transfer flow path and then the air pressure is supplied to the supply flow path.

A communication hole (33) communicating with the supply valve chamber (16) is formed. Air pressure is introduced into the supply valve chamber 16 through the supply passage 17 and the hole 24.
The received pressure acts on the A1 area shown in the figure (A1 × pressure), and the force acts in such a direction as to push the supply valve 19 (that is, the piston 13) upward. On the other hand, the received pressure (A2 × pressure) of the A2-fitted area works in the direction of pushing the piston 13 downward. Here, by making the A1 area and the A2 area the same, the forces acting in the vertical direction of the piston 13 are balanced. Therefore, the piston 13 is constantly urged downward by the coil spring 15 while balancing the forces acting on the piston 13 in the vertical direction.
Can be set so as not to protrude from the mating surface 6 of the bolster 1.
