(Operation of the invention) Next, the operation of the device configured as described above will be explained. The lifting cylinder (1) operates and the lifting table (3)
After raising the table, the stoppers (10) and (10) are vertically erected by the operation of a cylinder (not shown), and the lifting cylinder (1) is reversely operated to raise the lifting table (
3), the lower ends of the support rods (8b), (8b) come into contact with the upper ends of the stoppers (lO), (10), and the support rods (
8b) and (8b) are pushed up so that the rail (9) and the fixed rail (not shown) are at the same level. continue,
The mold cart (4) with the mold (7) mounted on the upper surface is moved to the rail (9) above the lifting table (3) via the fixed rail.
, (9) Carry it into the upper surface.

At this time, the mounting plate (18) attached to the mold trolley (4)
also enters into the space of the locking member (15) to a position facing the mounting plate (24).

Next, the lifting cylinder (1) is operated again to raise the lifting table (3) to receive the mold truck (4), and the clamping device (5) is used to place the mold truck (4) on the upper surface of the lifting table (3). )
After clamping the cylinder, the stoppers (10) and (10) are brought down by the reverse operation of the cylinder, and then the lifting cylinder (
1) operates in reverse to lower the lifting table (3) to the lowering end. At this time, the mounting plates (18) and (24) are also lowered at the same time, resulting in the state shown in FIGS. 1 to 3.

Subsequently, when the air cylinder (25) operates to extend the piston rod (25a), the mounting plate (24) is guided by the guide pins (23), (23) and the mounting plate (18) is guided by the guide pins (23).
), the guide pins (19) (19') are fitted into the guide bushes (19), (19), and the positional relationship is determined correctly by the guidance, and each outlet (20), (
21) and the plugs (20) and (21), and each socket (22) of the fluid coupling and the plug (22), and when the piston rod (25a) continues to be extended, the locking member (15) abut against the mounting plate (18), and these terminal devices are fully clamped and connected as shown in FIGS. 4 and 5. In this state, energy sources such as power and air and control signals are sent to the mold truck (4) and the mold (7) via the terminal device, and a molding operation is performed.

After the molding operation, when the mold cart (4) is carried out of the machine via the rail (9) and the fixed rail, the air cylinder (25) is first operated in reverse and the piston rod (25a) is retracted. The plate (24) has guide pins (23), (2
3) and separate the guide from the mounting plate (18) to each outlet (20), (21) and plug (20'),
), each socket (22) and plug (22) of the fluid coupling are also removed. Furthermore, when you move back, the mounting plate (24)
The nuts (23) and (23) on the back are the support brackets (1
3), the locking member (15) is pushed forward to form a gap with the back surface of the mounting plate (18), and returns to the initial starting state.

When the terminal device is disconnected in this way, as described above, the rail (9) and the fixed rail (not shown) are brought to the same level again, and the mold truck (4) is taken out of the machine and the mold is replaced. Thereafter, repeat the above operation.

(Effects of the Invention) As is clear from the above explanation, the present invention provides the following effects.

■ Productivity and work efficiency are improved because multiple connectors and fluid couplings can be connected and disconnected at the same time in an extremely short time.

■ By placing one mounting plate on the lifting table, the mold truck can be raised and lowered with the terminal device connected.

■ It is safe because no human effort is required to attach or detach each connector or fluid coupling.

■ Since many connectors, fluid couplings, etc. are arranged at regular intervals, the entire machine is compact, work is safe, and there is no damage to the couplings.

■ Due to its simple structure and linear operation, operation is reliable and economical, and maintenance and inspection are easy.

etc.
