Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for adding protrusions to an inorganic extruded product.

BACKGROUND ART Conventionally, building materials such as tiles and wallboards have been widely manufactured by extrusion molding of inorganic kneaded materials.

By the way, the cross-sectional shape of this type of extrusion molded product can be made into various shapes in the direction perpendicular to the extrusion direction, but it is impossible to make the cross-section in the direction along the extrusion direction arbitrary. there were.

For example, as shown in Figure 1, when molding a corrugated tile A, this ridge tile has a water return A in the valley A1 on the top surface of the tile.
2 is known to be very effective in terms of waterproofing, but it is impossible to integrally mold this type of water return piece A2 by extrusion molding. I had no choice but to rely on it.

On the other hand, when using a press bottom mold, the work is always repeated in a fixed cycle, including material supply, compression press, and demolding, resulting in a so-called batch system, which results in poor productivity and high costs. There are drawbacks.

In view of the above, the present invention has been made for the purpose of providing a device for adding protrusions to an inorganic extrusion molded product, which has a function of continuously adding protrusions even in extrusion molding. a fixed plate having an upper surface for forming a bottom surface of a shaped additional article; a slider that slides on the fixed plate and has a through hole formed in a shape that follows the side shape of the additional article; a weir plate in contact with the upper surface of the slider; a molding piston that fills and compresses molding material into the through hole of the slider on the fixed plate; and the slider moves through the weir plate so that the through hole portion touches the outer edge of the fixed plate. The punching piston is characterized in that it is comprised of a punching piston that, when extended further outward, demolds the molding material that has been compressed and filled in the through hole.

Next, the present invention will be explained using examples.

FIG. 2 shows a sectional view of an embodiment of the invention, and FIG.
shows a perspective view of the additional article.

Apparatus for adding protrusions to inorganic extrusion molded products of this invention (
(hereinafter referred to as protrusion adding device) 1 is an additional article having a desired shape;
For example, a fixed plate 1 having an upper surface 11A for forming the bottom surface of an additional article 2 such as the water return piece A2 shown in FIG.
1 is supported by the base frame 3 so as to be substantially parallel to the surface α of the extruded product G.

A slider 12 is installed on the fixed platen 11 so as to be in contact with the upper surface of the fixed platen 11 without a gap, and to be slidably driven by the cylinder device 4 .

The slider 12 is provided with a through hole 12A for forming the side surface 2B of the additional article 2, and the fixed platen 11
These are configured to form a female mold that forms the bottom and side surfaces of the additional article 2.

A weir plate 13 for scraping off excess material is provided on the upper surface of the slider 12 with its lower end touching the slider 12,
It is fixedly supported by the base frame 3.

The weir plate 13 is provided inside the material supply hopper 5, and the fixed platen 11 is also provided below the material supply hopper 5.

Further, the slider 12 is pushed out below the hopper 5 by the cylinder device 4, and the material B is placed in the through hole 12 at a position directly above the through hole 12A of the slider 12 when it enters the hopper 5.
A mold filling piston 14 is provided for filling and compressing the inside of A.

6 in the figure is an agitator that supplies and sends material onto the slider 12 when the mold-filling piston 14 is at the top dead center position.

On the other hand, the mold filling piston 14 fills the material, the slider 12 is retracted by the cylinder device 4, and the weir plate 1
3, the article 2 filled and compressed in the through hole 12A is removed from the mold immediately above the position where the through hole 12A extends outward from the outer edge 11B of the fixed platen 11, and placed in a predetermined position on the extruded product G. A punching piston 15 is provided for feeding.

Next, the operation of the apparatus of this invention will be explained.

FIGS. 4 to 6 are conceptual diagrams showing the operating state.

After the materials are put into the hopper 5 and sufficiently kneaded by an agitator 6 or the like, extrusion molding of the extrusion molded product G is started.

At this time, the mold filling piston 14 in the hopper 5 is at the top dead center, and the slider 12 is also located in the hopper 5.

Sufficient material is fed onto the slider 12 by the rotation of the agitator 6, and more material than is necessary to mold the additional article 2 is fed.

Next, the mold filling piston 14 descends as shown in FIG. 3 to fill and compress the material B into the through hole 12A of the slider 12.

At this time, since the material B is sufficiently supplied, the material is sufficiently filled and compressed into the female mold before the piston 14 comes into contact with the slider 12.

Next, as shown in FIG. 4, the mold-filling piston 14 rises, and the cylinder device 4 pulls out the slider 12 from directly below the hopper 5.

At this time, the material B' protruding onto the slider 12 is removed by the weir plate 13, and the compressed material B is filled only in the through hole 12A and pulled out.

Next, the through hole 12A of the slider 12 is inserted into the outer edge 1 of the fixed platen 11.
1B, the cylinder device 4 stops, and the punching piston 15 descends as shown in FIG. That's what I do.

At this time, the molded article 2 has already been sufficiently compacted by the molding piston 14, so the punching piston 1
5 and when supplied onto the extrusion molded product G, the molded article 2 does not lose its shape, and no excessive suppressing impact force is applied to the extrusion molded product G either.

Next, the piston 15 rises and the cylinder device 4 pushes the slider 12 below the hopper 5, completing the cycle.

The above steps are performed at a cycle pitch synchronized with the extrusion speed of the extrusion molded product G, and are operated at a cycle pitch of several seconds.

As the above example, the case of corrugated tiles was explained,
The present invention is not limited to this, and the same method can be applied to, for example, an extrusion-molded wall board material in which irregular protrusion patterns are provided at key points.

Since the present invention is configured as described above, when molding the additional article 2, the surplus material B is pushed into the female mold formed by the slider 12 and the fixed platen 11, and here it is compacted and formed. After that, the surplus material B is put on the weir plate 13.
Since the material is scraped off by the scraper, the quality of the added product can be made uniform. Also, when feeding onto the extrusion molded product, excessive pressing force is not applied to the molded product, and the amount of molding can be changed. I never let anyone do it.

Furthermore, since the operating cycle can be shortened, it is possible to add the additional article 2 onto the molding machine G with sufficient follow-up even with conventional extrusion molded products. It has various effects, such as being able to produce molded products, saving labor, and significantly reducing manufacturing costs.
