2. Description of the Related Art A molded product obtained by extrusion-molding or press-molding a composition composed of water and a hydraulic inorganic substance such as cement, mortar and gypsum and curing the composition has been used for various structural materials since ancient times. ing. That is, for example, clay roof tiles such as Ibushi roof tiles are well known as roof tiles and have been most often used.

Recently, however, the amount of good quality clay has decreased, and it has become difficult to mass produce good performance clay. Therefore, roof tiles using so-called hydraulic inorganic moldings such as thick slate and cement roof tiles have begun to be produced instead. As a method for producing such a hydraulic inorganic molded body, for example, a method has been proposed in which dehydration molding is performed, and then the upper mold is vacuum-sucked to remove the mold (see Japanese Patent Laid-Open No. 1-215506).

However, in this method, in order to improve the moldability, an excessive amount of water is used with respect to the amount required for hardening the hydraulic inorganic substance, so that the dehydration step requires a long time.
In addition, the molded body obtained by using excess water has a coarse structure and is weak in strength.
Therefore, in order to obtain a molded product such as a roof tile having a sufficient load resistance, the thickness of the molded product, that is, the weight has to be increased, which is disadvantageous in terms of construction and cost. In addition, when the molded product is removed from the mold, since vacuum suction is performed through the filter cloth through the dehydration hole of the upper mold, there is a problem that the fiber or powder material is likely to be clogged during dehydration.

However, even in the above method, the flat plate-shaped molded product can be adsorbed and demolded by a suction cup, but in the case of a molded product having an uneven thickness and a complicated shape, Adsorption is difficult. That is, in order to reduce the wall thickness, an uneven thickness portion such as a reinforcing rib is provided, or in the case of a thick molded body, the weight of the molded body becomes large, so that the suction holes due to the weight are eliminated. However, if a large number of vacuum holes are provided, a large number of dents may be formed on the surface of the molded body on the side opposite to the suction surface, resulting in a poor appearance.

Further, a recess corresponding to the protruding portion such as the rib of the suction cup is provided with a protruding portion.
When the recess is made larger than the size of the protrusion so that the protrusion smoothly enters the recess when setting the suction cup,
Since there is a gap between the protrusion and the wall surface of the recess, there is also a problem that the protrusion may lose its shape during adsorption. In view of such circumstances, the present invention provides a suction cup capable of adsorbing a molded body having an uneven thickness portion such as a reinforcing rib without causing the mold to collapse or causing a defective appearance. It is an object.

The suction cup according to the present invention comprises:
In order to achieve such an object, a suction cup for adsorbing and demolding a molded body having a protruding portion which becomes thick and is formed on the surface obtained by press molding, wherein the molded body has a suction surface. A recessed portion slightly larger than the projection portion is formed in the portion corresponding to the protrusion portion, and the recessed portion of the suction surface and the suction surface excluding the portion within 30 mm from the recess edge are 2
Vacuum holes with a diameter of 2 mm to 10 mm are formed at intervals of 0 to 100 mm, and the sag along the end face of the molded body is 0.3 to 5 times the thickness of the molded body from the peripheral edge of the suction surface. The structure is extended.

In the above structure, the material of the sagging is not particularly limited as long as it can adhere to the peripheral surface of the compact and maintain a vacuum when the compact is vacuum-adsorbed by the suction cup. If the extension length is too short,
If the molded body does not have a close contact effect and the adsorption performance is poor, and it is too long, it will prevent the molded body from approaching the receiving plate during demolding, and when the molded body is dropped onto the receiving plate, deformation such as distortion will occur in the molded body. Since it is liable to occur, it is 0.3 to 5 times the thickness of the molded body,
More preferably, it is 0.5 to 2 times.

When the diameter of the vacuum hole is less than 2 mm, the deposits on the molded body are apt to be clogged, and when it exceeds 10 mm, no further effect is observed, and the material is sucked into the vacuum hole to form a dent. The diameter is set to 2 to 10 mm, more preferably 3 to 7 mm. It is not necessary to provide the vacuum holes at equal intervals, and if the distance between adjacent vacuum holes is less than 20 mm, no further effect is observed, and if it exceeds 100 mm, the degree of vacuum that can adsorb the compact is obtained. Cannot be obtained, and adsorption failure tends to occur, so 2

Further, if the vacuum hole is provided at a position less than 30 mm from the protruding portion and the peripheral edge of the protruding portion, a gap is created between the protruding portion and the inner wall surface of the concave portion, so that suction is performed. Since a part of the protruding portion is sucked in the strong direction of the protruding portion, and the protruding portion loses its shape, it is provided at a position other than 30 mm from the protruding portion and the periphery of the protruding portion. The curable inorganic composition to be a molded article is not particularly limited as long as it is used for producing a structural material, but is not limited to, hydraulic inorganic materials, fillers, reinforcing fibers, molding aids, water, etc. Those containing are preferred.

According to the above construction, the suction cup is arranged above the molded body press-molded by the press machine so that the projection of the molded body faces the concave portion of the suction cup, and the suction surface is brought into close contact with the surface of the molded body.
At this time, since the concave portion is slightly larger than the projecting portion, the projecting portion does not lose its shape, and the suction surface adheres to the surface of the molded body.

Then, the molded body is sucked through the vacuum hole to be sucked by the suction cup. At this time, since the sagging is in close contact with the side peripheral surface of the molded body, a sufficient suction force can be obtained even with a small suction force, and the molded body is sucked by the suction cup. Moreover, since no vacuum hole is provided in the portion of the protruding portion and at a position less than 30 mm from the periphery of the protruding portion, a large vacuum force does not act on the protruding portion, and the protruding portion does not lose its shape.
