Abstract

PURPOSE:To eliminate undue influences caused by involved air and obtain moldings with excellent quality by placing a porous sheet on the surface of a receiving plate for an extruded molding material. CONSTITUTION:A molding material is extruded from a mold 2 while kneaded by an extruder 1, and while transporting a receiving plate 3 by means of a roller conveyor 5, a molding material 3 extruded from the mold 2 is received thereon and delivered therefrom. Wherein on the receiving plate, a porous sheet 8 made of nylon woven fabric is put previously. Consequently, even air is involved between the receiving plate 3 and molding material 4 upon receiving the molding material 4 by the receiving plate 3, it flows out of the porous sheet 8. Thus the occurrence of craters on the molding material and the loss of patterns can be prevented and moldings with excellent quality can be obtained.

(Prior art) Conventionally, as shown in FIG. 7, a building having a decorative uneven pattern A on the protruding corner side has been constructed using a hydraulic inorganic molding material such as cement-based, gypsum-based, or rhusium silicate material as a molding material. In order to manufacture corner accessories, as described in Japanese Patent Application Laid-open No. 60-44303, in the case of cement-based materials, cement is used as the main material, and additives such as silica stone and fibers are mixed into it. Furthermore, the composition to which sufficient water is added to plastically deform during molding is put into an extruder 1 as shown in FIG. The molding material 4 is manufactured by extruding the molding material 4. At this time,
The tray 3 loaded with the molding material 4 is transferred on a roller conveyor 5 that supports it at a speed corresponding to the extrusion speed, and the molding material 4 is cut together with the tray 3 into appropriate dimensions. Thereafter, the molding material 4 is taken out with the tray 3 or taken out from the tray 3 and charged onto the lower die 7 of the press 6 as schematically shown in FIG. It is manufactured.

In this case, whether to charge the molding material 4 together with the tray 3 into the press machine 6 or to take it out from the tray 3 and charge it into the press machine 6 is selected depending on the shape retention of the molding material, but generally speaking When curing and hardening after press forming,
From the viewpoint of workability in processes such as transportation to a curing room, storage, and curing processing, it is often left on a tray until curing and hardening are completed. (Problem to be solved by the invention) By the way, in any case, in the case of the above-mentioned prior art, when the molding material 4 is first extruded and supplied onto the tray 3, air is caught between the molding material 4 and the tray 3.

Next, a similar problem occurs when charging the molding material into the press. That is, when charging the molding material into the press machine, the molding material 4 is taken out from the receiving tray 3 and placed in the lower mold 7.
If it is charged from above, air will be drawn in between the molding material 4 and the lower die 7 at the time of charging, and the molding material 4 will be
Air is caught between the pattern mold 9 attached to the upper mold 6 and the pattern mold 9 attached to the upper mold 6.

In addition, when pressing is performed with the molding material 4 placed on the tray 3, air is caught between the molding material 4 and the pattern mold 9 attached to the upper mold 6 during pressing.

In this state where air is drawn in, the air bubbles caused by the drawn-in air cause pockmarks to occur on the bottom or top surface of the molding material 4 at locations corresponding to the bubbles, making it impossible to obtain a smooth molding surface and impairing the quality of the appearance. For example, in the case of the above-mentioned accessories, the pock occurs on the back side of the molded product, so even if it is laminated to other wall materials, there is a problem that sufficient adhesion cannot be obtained. Furthermore, on the upper surface, that is, the surface on which the pattern is engraved, the pattern tends to become thinner (shallower) or disappear in areas corresponding to the air bubbles, which has a negative effect on quality. be.

On the other hand, when the molding material 4 is charged directly onto the lower mold without passing through the receiving tray, or when the molding material 4 is placed on the receiving tray 3 instead of being directly received from an extruder, the separately manufactured molding material is manually charged. Even if it is placed on the tray 3, air will be drawn in between the molding material 4 and the lower mold 7 or the tray 3, and the pattern attached to the molding material 4 and the upper mold 6 will be removed during pressing. Air is caught between the mold 9 and the mold 9. The problems caused by the entrained air thus generated are the same as those described above.

(Effects of the Invention) In the first and second aspects of the present invention, since a tray with a porous sheet placed on the upper surface or a tray with ventilation holes is used, air is caught between the extruded molding material and the tray. teeth,
When the molding material is placed on the tray, it flows out through the holes in the porous sheet or the vents in the tray. Therefore, it is possible to prevent the formation of pock marks on the surface of the molding material and the disappearance of the pattern, and to obtain a product of excellent quality.

In the third aspect of the present invention, when pressing the molding material, the molding material is charged into the press machine without using a tray, and a porous sheet is interposed above or below the molding material, so that the molding material does not reach the top of the lower mold. Even if air is caught between the molding material and the lower mold when it is charged into the mold, it will flow out from the porous sheet. Furthermore, air trapped between the molding material and the upper mold during press molding also flows out from the porous sheet. Therefore, it is possible to prevent the formation of pock marks on the surface of the molding material and the disappearance of the pattern, and to obtain a product of excellent quality.

In the fourth or fifth aspect of the present invention, when the molding material is pressed together with a receiving tray, a porous sheet is interposed above or below the molding material, or a receiving tray provided with ventilation holes is provided. During pressing, the air trapped between the molding material and the upper mold, or between the molding material and the tray, flows out through the vents in the porous sheet or the tray. Therefore, it is possible to prevent the formation of pock marks on the surface of the molding material and the disappearance of the pattern, and to obtain a product of excellent quality.
