DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a molding apparatus for a paving block capable of forming a single or a small number of paving blocks by an operator alone.

[0002]

2. Description of the Related Art Pavement blocks have conventionally been mass-produced by a large-sized automatic molding apparatus in which a large number of dies are arranged. However, pavement blocks are different from molded materials of the same standard made of concrete block materials that are used to construct the walls and walls of general buildings, and the color of the block materials has been changed as the sidewalks, promenades, and the streets of shopping streets have become more beautiful. As a manufacturer of block materials, brochures, catalogs, and product samples that match the requirements and sizes of various construction designs of the installer are created, and small quantities of various standards and designs are created. Need to provide. Therefore, processing a required number of single or several block materials to be molded as a sample or a sample for such an order using a conventional large-sized device is wasteful and quick in terms of the number of processes and molding costs, and There is a disadvantage that efficient labor-saving processing is lacking.

[0003]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, it is an object of the present invention to provide a mold apparatus which can rapidly and efficiently process and mold even a single worker without the need for a conventional large-scale automatic molding apparatus. did.

[0004]

Means for attaining the above object include a reverse striking operation which can be performed by a single or a small number of workers, each comprising a receiving die and a pressing die laid on the bottom of the receiving cavity. A mold, a U-shaped intermediate frame supporting the mold from below, and a mold base on which the mold and the U-shaped intermediate frame are installed. Provide a projecting support part slightly smaller in size than the stamping die that supports the stamping die of the reverse hitting die from below, and a pedestal that is the same height as the supporting part close to the projecting support part, the mold base, the intermediate frame The gist of the present invention is a molding die apparatus for forming one or a small number of paving blocks, which is formed and demolded through a body and a pedestal.

[0005]

The molding die is supported by the U-shaped intermediate frame from below, and the pressing part of the die is strongly supported by the projecting support provided on the die base. After filling and casting the surface layer material and the block forming material that is the main material into the inside, the mold is temporarily slid laterally on the receiving base on the mold base and set in the lower part of the mold. The frame is removed from the mold base, and the mold that has been stably slid on the receiving base is slid again on the projecting support portion of the mold base, and then the die receiving mold is moved to the mold base. The block molded by pressing down is removed from the receiving mold. The demolded molding block is slid laterally on the receiving portion of the mold base together with the bottom die, dried and solidified, and then the die is released to complete the molding operation.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. The embodiment shows a molding die for a single (one) pavement block,
In the drawings, FIGS. 1 to 4 show molding by a die, 1 is a receiving die for a reverse hitting die 10, and 3 is a pressing die laid on the bottom inside the receiving cavity 2. Conventionally, the pressing die is set on the upper surface and press-molded. However, in the embodiment of the apparatus of the present invention, the pressing die is laid at the bottom of the receiving cavity by a reverse hitting die. Reference numeral 4 denotes an operation handle of a worker. The block material is processed by an operator alone. The block material is formed by filling a color surface material 5 on the upper surface of the pressing die 3 and compacting it with a hammer tool or the like, and then kneading cement, water, sand, etc. on the upper surface thereof. Main material 6
Is filled and solidified with a hammer or the like, and the uneven surface 6 'on the upper surface is shaped and finished with a trowel or the like. The work process of placing the paving block material described above is performed by the reverse driving die 1 shown in FIG.
0 and a U-shaped intermediate frame 11 are molded on a mold apparatus 20 which is combined on a mold base 12, and the mold is released. The demolding process will be described with reference to the drawings of the embodiment. The mold base 12 of FIG. 6 and the U-shaped intermediate frame 11 of FIG. 5 installed on the base are combined and designed as the mold apparatus 20 of FIGS. 7 to 10, and the mold 10 is shown in FIG. U-shaped intermediate frame 1 supported from below
The block is reversely formed on the projecting support portion 14 by the steps shown in FIGS. The pressing die 3 laid in the cavity 2 of the receiving die is further supported by a protruding supporting portion 14 on the mold base 12, but the protruding supporting portion 14 is formed to have a slightly smaller size than the pressing die 3. It is designed so as not to hinder the demolding action of the block m. Reference numeral 15 denotes a receiving stand provided on the mold base, which is designed to have the same height as the projecting support portion 14, and the interval A between the projecting supporting portion 14 and the receiving stand 15 is shorter than the width B of the pressing die 3. The movement of the mold 10 which is set on the width and which molds the block material is supported in a stable state, so that the lateral sliding action of the mold is smooth and the mold block is prevented from being deformed.

The mold in which the block material is molded in FIGS. 1 to 4 is a mold 1 as shown in the first and second steps of demolding in FIGS.
0 is slid once on the receiving base 15 and the U-shaped intermediate frame 11 supporting the receiving die 1 and the pressing die 3 from below is pulled out from the lower part of the die, thereby facilitating the block release of the die. After shifting the intermediate frame 11 in the direction of the arrow, the mold 10 on the receiving stand is horizontally slid again while supporting the mold on the projecting support portion 14 with both hands in the third step as shown in FIG. As shown in the fourth step of FIG. 10, the mold 10 returned to the protruding support portion 14 has the receiving mold 1 pressed down on the mold base 12 with both hands, and is filled and molded into the receiving cavity. Remove the material m. The removed molded block m is horizontally slid again with both hands on the receiving table 15 together with the pressing mold 3 to solidify, and after drying, the pressing mold 3 is peeled to complete the formed block m as a processed product. Note that the same applies to the mold of the odd-shaped block.
Although not shown in the drawings, a plurality of molds can be simultaneously formed by using an apparatus having a series of dies. The molding process is performed by using the weight of the mold
kg), it is suitable to form a block by one person, and simultaneous multiple molding of a block is a work by two or more people.

[0008]

As described above, according to the mold apparatus of the present invention, one or several deformed blocks can be formed quickly and efficiently by preparing the corresponding molds, and a small number of workers can work alone. It is possible to mold various kinds of precise blocks, which is extremely effective in terms of labor saving and economic cost of molding.
