Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention provides a joint for supplying energy sources such as air, gas, power, etc., cooling water, control signals, etc. to a mold cart running in a mold making machine. This invention relates to a terminal device for a mold making machine that can automatically attach and detach.

(Prior art) A mold truck that moves laterally in a mold making machine includes a mold opening/closing cylinder, air or hydraulic piping to a fluid cylinder for loose pieces, electric or gas wiring or piping for a heat source for mold heating, and metal There are many pipes and wiring for energy supply and control, such as cooling pipes around the mold, and electrical wiring for operating signals such as limit switches. In addition, during mold production, the mold cart is fixed to the top of the lifting table and moved up and down, so it is necessary to use flexible piping and wiring for the mold cart, and when replacing the mold, the clamp must be used. In order to release the mold cart and pull it out of the machine from the top of the lifting table, it is necessary to take out the wiring and piping, but this removal work is a manual process that is time-consuming and hinders productivity. .

By the way, recently, in order to solve this problem, a terminal trolley for mold making machines (Special Publication No. 1983-39020) has been proposed that can automatically attach and detach supply joints for wiring, piping, etc. to the mold trolley. However, there are problems in that it requires multiple connection and detachment mechanisms with the mold truck and is expensive, and it cannot be used in a mold making machine in which the mold truck moves up and down during mold making.

Subsequently, the mold cart 4 with the mold 7 mounted on its upper surface is carried through the fixed rail onto the upper surface of the rails 9, 9 above the lifting table 3. At this time, the mounting plate 18 attached to the mold truck 4 also enters into the space of the locking member 15 to a position facing the mounting plate 24.

Next, the lifting cylinder 1 operates again to raise the lifting table 3 to receive the mold truck 4, and after clamping the mold truck 4 on the upper surface of the lifting table 3 with the clamp device 5, the cylinder is reversely operated. to lower the stoppers 10, 10, and then lower 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.
The state will be as shown in FIGS. 1 to 3. Subsequently, the air cylinder 25 operates and the piston rod 25a
When the mounting plate 24 is extended, the guide pins 23, 2
3, the guide pins 19', 19' are fitted into the guide bushes 19, 19, and the positional relationship is determined correctly by the guide pins 19, 19, and the respective outlets 20, 21 and plugs 20', 2
1', when the sockets 22 of the fluid coupling and the plug 22' are fitted together, and the piston rod 25a continues to be extended, the locking member 15 locks onto the mounting plate 1.
8, 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 carrying the mold truck 4 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 moved.
When the mounting plate 24 is pulled in, the guide pins 23, 2
3, the guide bushes 19, 19 and guide pins 19', 19', the outlets 20, 21 and plugs 20', 21', and the sockets 22 and plugs 22' of the fluid coupling also separate. . Furthermore, when the vehicle moves backward, the nuts 23' and 23' on the back side of the mounting plate 24 come into contact with the support bracket 13, and the locking member 15 is pushed forward to form a space between it and the back side of the mounting plate 18, and the first starting Return to state. When the connection of the terminal device is released in this way, as described above, the rail 9 and the fixed rail (not shown) are again brought to the same level and the mold carriage 4 is placed at the same height.
Take it out of the machine and replace the mold. Thereafter, repeat the above operation.

(Effects of the Invention) As is clear from the above description, 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 disposing one of the mounting plates 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 a large number of connectors, fluid couplings, etc. are arranged at regular intervals, the entire machine is compact, the work is safe, and the couplings are not damaged.

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

etc.
