BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an attaching / detaching device for attaching / detaching a brick forming die tooling set having an upper plunger and a lower plunger to a die holder and for attaching / detaching the die tooling set to a die exchanging transfer carriage. The present invention relates to a brick forming press provided with a raw material supply device.

2. Description of the Related Art Generally, a brick-forming press equipped with a device for rationalizing the process, for example, for easily and quickly exchanging a mold, has been known in the art. Are disclosed in Japanese Patent Publication No. 61-49085. This is a technique for maintaining a high vacuum in a vacuum brick molding machine and unmanning the brick molding operation.
No. -402005 proposes a mold, which can be used for frequent mold replacements several times a day, or changes in molds and raw materials.
That is, this is a technique for exchanging the die tooling set and the raw material in a short time, which will be described with reference to FIG.

A mold 28 having upper and lower plungers 26 and 27 is transferred to the front surface of the press by a transfer carriage 29 for mold replacement, and set in a mold holder 25 by a mold withdrawing cylinder 34. In addition, the raw material charger 32, the hopper 31, and the charger cylinder 33.
Since the transfer carriage 30 provided with is provided so that the rear surface of the press 41 can be transferred laterally, different raw materials can be transferred to the hopper 2
By providing a plurality of transfer carriages 30 accommodated in 1 and replacing the transfer carriages, the raw materials can be changed in a short time.

However, in the above technique, since the plurality of transfer carriages 30 having a fixed height are provided, the die holder 25 is provided.
Is fixed to the press 1, and the upper and lower pressure pistons P1,
It is restricted to the press of P2 pressure molding method. Therefore, the above technique cannot be applied to a hydraulic type or a screw type die floating type press in which the die holder 25 moves up and down.

[0005]

DISCLOSURE OF THE INVENTION The present invention, in a die floating type press in which a die holder moves up and down and is pressure-formed only with an upper plunger of a press body, as in the case of die exchange, a raw material can be easily It is intended to provide a brick forming press that can be replaced in a short time.

[0006]

According to the present invention, a brick molding die tooling set having an upper plunger and a lower plunger is attached to and detached from a mold holder, and the die tooling set is used as a mold exchanging transfer cart. In a brick forming press provided with a detaching device for attaching and detaching and a raw material supply device, a plurality of transfer carriages are provided, the raw material supply device on the carriage, a moving means for moving the raw material supply device back and forth, and the raw material supply device. Elevating means for raising and lowering the apparatus and positioning pins for positioning the die holder are provided.

The lifting means is preferably a pantabluff type hydraulically operated.

Further, it is preferable that the moving means is a dolly operated by hydraulic pressure.

[0009]

[Explanation of Operation and Effect] When exchanging the raw material in the die floating type press constructed as described above, the clamp is released on the transfer carriage and the raw material supply device is retracted to remove the positioning pin and the transfer carriage is moved in the lateral direction. To the rear of the press, and adjust the height with the die holder by the elevating means.
The work can be started immediately by advancing the raw material supply device, positioning it with the positioning pin and clamping it. Since the raw material supply device moves up and down together with the mold holder by the elevating means, it does not hinder the pressing work. Further, since the mold attaching / detaching device is fixed to the mold holder, it does not hinder the operation.

Embodiments of the present invention will be described below with reference to the drawings.

1 and 2, the press body 1 is provided with an upper piston 2 and a die holder 3 supported by a plurality of cylinders 4, 4 so as to be vertically movable.
Further, a mold drawing cylinder 5 is fixed to the mold holder 3. The transfer carriage 9 for exchanging the die, which holds the die 8 which is the die tooling set including the upper plunger 6 and the lower plunger 7, is composed of the press body 1
It is provided so that it can travel freely on rails 10 and 10 provided on the front side of.

A transfer carriage 12 is movably provided on rails 11 provided on the rear side of the press body 1. The carriage 13 is mounted on the rails 15 and 15 provided on the floor 16 of the transfer carriage in a direction perpendicular to the rail 11.
Is movably provided by a cylinder 14. Further, the carriage 13 is provided with a charger frame 18 via a lifting device 17 (a pantograph type in the illustrated example), and the charger frame 18 has a charger 19 attached thereto.
And a charger cylinder 20 are provided. The hopper 21 provided with the feeder 22 is fixed to the transfer carriage 12. Further, the charger frame 18 is provided with a positioning pin 23 and a clamp device 24.

Therefore, when exchanging the raw material, the clamp device 24 is released and the cylinder 14 is operated to operate the carriage 13.
Is retracted from the press body 1 (see FIG. 2), and the transfer carriage 1
2 is moved along the rail 11, a transfer carriage 12a (not shown) containing another raw material prepared in advance is moved to the rear surface of the press main body 1, and the die holder 3 is moved by the elevating device 17.
When the cylinder 14 is operated to move the carriage 13 forward so as to be positioned by the positioning pin 23 and clamped by the clamp device 24, the press work using the replaced raw material can be started.

When the die tooling set, that is, the die 8 is exchanged, the cylinders 4 and 4 for moving the die holder 3 up and down are operated to transfer the die exchanging transfer cart 9.
Match the height of the mold holder 3 to the
You can operate.

[0015]

EFFECTS OF THE INVENTION Since the present invention is configured as described above, even in a die floating type press in which pressure molding is performed only by the upper plunger, the transfer carriage charged with the raw material can be easily replaced. Similar to the mold replacement, the raw materials can be replaced easily and in a short time.
