[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an attaching / detaching device for attaching / detaching a brick molding 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. And a brick press provided with a raw material supply device.

[0002]

2. Description of the Related Art As such a conventional apparatus, a mold floating type press is known as shown in FIGS.
When exchanging the die tooling set, that is, the die, the die exchanging transfer carriage 31 is stopped in front of the press 32, and the lower plunger pull-up cylinder 33 and the pressurizing piston 3 are used.
4 is operated to bring the upper and lower plungers 39 and 40 into contact with each other at the center of the mold, loosen the clamps 36 and 37, extend the mold drawing cylinder 38, and transfer the mold to the carriage 31. Then, after the carriage 31 is transferred, the carriage 31a holding the new mold is stopped in front of the press 32, and the new mold is mounted on the press by the procedure reverse to that when the mold is removed.

[0003]

The above-mentioned device has been sufficiently successful in, for example, die replacement due to wear of the liner portion of the die tooling, but in recent years, lots of small lots of other types including brick blending raw materials have been obtained. Then, it became necessary to replace the material.

When the blended raw material changes, the raw material remaining in the table of the charger 41, the blending input box 42 and the hopper 43 is completely removed, and after cleaning the inside of each, the new raw material is loaded into the hopper 43, and further the mold holder. It is necessary to clean the upper part of 35, etc., and changing the blending raw material has become a weak point of this type of press.

As shown in FIG. 4, two hoppers 43, 4 are provided.
A method of transferring 3a onto the charger 41 is also conceivable, but since the charger 41 operates up and down, the structure is complicated and the raw material hopper 21 is also moved up and down, so that the adjustment work is troublesome and the cost is increased. Becomes

The present invention, like the mold, makes it easy to use raw materials,
The purpose is to provide a brick press that can be replaced in a short time.

[0007]

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 die holder, and the die tooling set is used as a die exchanging transfer cart. In a brick press provided with a detaching device for detaching and attaching and a raw material supply device, a plurality of transfer carriages are provided, the detachable device and the raw material supply device are provided on the carriage, and a positioning pin for positioning the transfer carriage on the brick press. Is provided.

[0008]

In the brick press equipped with the mold exchanging device configured as described above, when exchanging the blended raw material, the transfer carriage equipped with the hopper with the remaining blended raw material releases the positioning by the positioning pin. Separated from the press and transferred,
Next, the transfer carriage charged with the newly prepared raw material prepared in advance is positioned in the press by the positioning pin.

[0009]

Embodiments will be described below with reference to the drawings.

In FIGS. 1 and 2, a press body 1 having an upper piston 2 on the upper part and a lower piston 3 on the lower part.
Has a die holder 5 fixed by a groove 4 provided inside, and a die replacement transfer carriage 9 holding a die 8 having an upper plunger 6 and a lower plunger 7 is a press machine. Rail 1 provided on the front side of the main body 1
It is provided so that it can run freely on 0 and 10.

The transfer cart 20 includes a raw material hopper 21, which is a raw material supply device, a raw material charging box 22, and a charger cylinder 23.
Rails 30 and 3 provided on the rear side of the press main body 1 with wheels and equipped with a die drawing cylinder 24 that is a detaching device.
It is provided so that it can run freely on 0.

Then, it is positioned on the press body 1 by a positioning pin 25 provided on the transfer carriage 20.

The operation will be described below. Mold replacement is performed by the upper piston 2, the lower piston 3 and the mold drawing cylinder 2
What is done by operating 4 is the same as the conventional one. On the other hand, when exchanging raw materials, the rod 2 of the mold drawing cylinder 24
6 is retracted, the positioning of the positioning pin 25 is released,
The transfer carriage 20 is transferred to the position B in FIG. 2, and a transfer carriage of the same shape (not shown) prepared in advance is transferred to the rear side of the press main body 1 on the rails 30 and 30 and is positioned by the positioning pin. End the exchange.

[0014]

Since the present invention is constructed as described above, the charger of the conventional pressing device is used in the mold holder 3
In the structure that moves up and down together with 5, the transfer device 20 needs a vertical movement adjustment work. However, in the present invention, since the die holder 5 is fixed without moving vertically, the work can be simplified. In addition, since the raw material of the transfer carriage is exchanged by the positioning pin, the raw material can be easily exchanged in a short time like the die exchange.

In addition, unmanned operation can be expected by suitably controlling the number of trolleys and the relation with the product removal.
