[0013]

Next, the operation of the present invention will be described.

First, in the composite spinneret attached to the spinneret base shown in FIGS. 1 to 3, a split spinneret having a spinneret inner frame made of a fluid hardening material is mounted on the spinneret base of a clay forming machine. ,
Each of them is attached via a mounting bolt, and several thin plates for adjusting the thickness are provided on the joint surface of the split type base.

In some cases, an adjusting plate that defines the longitudinal width of the tile base material is attached to the joint surface of the split type die.

Therefore, the tile base material is continuously fed out through the mouthpiece of the inner frame of the split type mouthpiece made of the fluid hardening material.

When the mouthpiece of the inner frame of the mouthpiece is abraded through the continuous feeding of the roof tile base material, the degree of wear is adjusted by the removing method of the adjusting plate to obtain a regular size (so-called regularity). (Thickness) roof tile base should be paid out.

In the above-mentioned method of removing the thin plate for adjustment, normally, when the degree of wear of the mouthpiece of the inner frame of the mouthpiece is large,
Remove the split-type base from the base and remove the unnecessary inner frame of the base remaining on the inner surface of each base by crushing and cutting, etc., and in principle, the base of the original type The outer frame.

Thereafter, a split type outer frame of the die is mounted on the molding table.
For example, they are united with each other via a tightening bolt (not shown), and are placed on the forming table, for example, with the kneading material receiving side facing upward.

An inner peripheral surface having a size slightly larger than the outer size of the tile base material having the concave-convex locking portion is formed on the united outer frame of the divided type mounted on the molding table.

After that, a model for roof tile base molding having a drawing gradient is inserted into the inner peripheral surface and fixedly mounted between the molding base and the outer frame of the die.

As a result, a space is formed between the inner peripheral surface and the outer peripheral surface of the model. Therefore, in this space, a flowable hardening material made of concrete, plastic, aluminum, etc. ).

After that, when the fluid hardening material is hardened, the model is removed, and an inner die frame having a mouthpiece portion for roof tile base forming is formed there.

The split type spinneret having the spinneret inner frame made of the fluid hardening material thus constructed is removed, for example, by tightening bolts (not shown). The split type base with a frame is divided, and thereafter, it is attached to the base with substantially the same operation and procedure as described above.

Thereafter, the method of use and other operations are the same as those described above. Unless the metal material is damaged, the inner frame of the die made of the fluid hardening material is repaired again or the shape of the model is changed. It is useful for reuse, production of multi-variety tile base material, facilitation of mouthpiece management, cost reduction, etc.

Next, in the composite die of the die which also serves as the die base shown in FIGS. 4 to 6, the die which also serves as the die base having the die body made of a fluid hardening material is used as a base of a kneading machine. It is attached to the collar piece of the box through a mounting bolt, and the protective plate provided on the mouthpiece that also serves as the mouthpiece base is attached to the side of the box.

Therefore, through the mouthpiece portion of the mouthpiece body which is protected by the protective plate and is composed of the fluid hardening material,
The tile base is continuously fed.

Note that, unlike the above-mentioned example, since this example is an integral type, in principle, adjustment of the mouthpiece portion by the adjusting plate is impossible. However, the width adjustment in the longitudinal direction is configured to be adjustable via the adjustment plate as in the above.

If the mouth of the die is worn due to continuous molding of the tile base material, the die that also serves as the die base is removed from the collar piece of the box and then the protective plate is removed. The unnecessary base body is removed by crushing, cutting, etc., and as a general rule, the base is provided with the base opening provided with the concave-convex locking portion made of the original metal material.

After that, the dope is placed on the forming table so that the dope receiving side of the die is facing up.

A model for tile base molding having a withdrawal gradient is inserted into a mouthpiece opening having a concave-convex locking portion of a mouthpiece stand placed on this forming stand, and the model between the forming stand and the mouthpiece opening is inserted. Place it fixedly on.

As a result, a space is formed between the mouth opening and the outer peripheral surface of the model, and this space is filled with the fluid hardening material.

Thereafter, when the model is removed when the fluidity hardening material is hardened, a die body having a die mouth portion for forming a roof tile base is formed here, and then the dough body of the die body is received. Attach the protective plate that protects the side through the mounting bolts.

The thus-configured mouthpiece which also serves as the mouthpiece base is attached to the collar piece of the sack box by substantially the same operation and procedure as described above.

The subsequent method of use or other work is the same as that described above. Unless the metal material is damaged, the inner frame of the die made of the fluid hardening material is repaired again or the shape of the model is changed. It is useful for the effect that it can be reused or for the production of multiple types of tile base materials, or for facilitating the management of the base and reducing the cost.
