Description

[Detailed description of the invention] <Industrial application field> This invention is applicable to L-shaped unit panels used to assemble and form prefabricated aquariums, such as architectural frames such as pillars and ceilings where aquariums are assembled and installed. This invention relates to an improvement in a mold for integrally molding an L-shaped unit panel used when assembling and forming an aquarium into a deformed form in which the ceiling, side walls, and bottom of the tank itself are deformed in order to avoid collision with the water tank.

<Prior art> Conventionally, a mold for integrally molding an L-shaped unit panel is an L-shaped integral mold in which a horizontal mold part and a vertical mold part are integrally connected in an L-shape. An upright surface on one side around the L-shaped part consisting of a horizontal molded part and a vertical molded part which are recessed in both mold parts and connected in an L-shape, for example, the upper end upright surface of the vertical molded part is the vertical mold part. The mold structure is formed by a block mold that is separable from the mold body, and the molded L-shaped unit panel is removed from the L-forming part by removing the block mold. Ta.

However, in the conventional type, the upper end of the vertical mold part, which is the molding surface for forming the raised edge (flange part) on one side of the L-shaped unit panel, is a block mold. After forming the L-shaped unit panel, by removing the block mold, the entire upper part of the upright edge of one side of the L-shaped unit panel formed in that part is opened. The demolding operation was performed by grasping the upright edge and lifting it upward (in the vertical direction).

However, since the molded L-shaped unit panel adheres closely to the horizontal molding part and the vertical molding part, it is difficult to easily remove it from the mold.

Therefore, in order to solve this problem, it may be possible to form all the raised surfaces on each side around the L-shaped part with a block mold, but such a mold structure would reduce the assembly work. Not only will it be a hassle,
Manufacturing the mold itself becomes troublesome and complicated.

<Problems to be solved by the invention> The problems to be solved by the invention are to facilitate the production of L-shaped unit panels by making it easy to assemble and disassemble, that is, to demold the molded L-shaped unit panels. To provide a mold for an L-shaped unit panel, which improves performance and is convenient for storage management when not in use.

<Means for solving the problems> The technical means taken by the present invention to solve the above problems are: a horizontal type, a vertical type that is detachably connected to the horizontal type in an L-shape, and a vertical type that is connected to the horizontal type in an L-shape. It consists of reinforcing pieces on both the left and right sides that are detachably attached to the connecting corners of both the horizontal and vertical types, and the horizontal type has a rectangular horizontal molded part recessed on its upper surface excluding the upper peripheral surface, and the horizontal molded A hanging stepped portion for vertical type mounting is formed in a substantially U-shape in plan by stepping the rear side upper surface circumferential portion of the portion downward, and the upper surface circumferential surface adjacent to both vertical surfaces of the hanging stepped portion is A first stopper plate for mold connection positioning is attached to the opposing upper side surfaces of both sides, and a screw fixing plate is opened toward the rear at the lower part of the upper side surfaces of both sides and the lower part of the horizontal long side surface of the hanging step. On the other hand, the vertical type has a vertical molded part on the front surface other than the front peripheral surface, which is continuous in an L-shape on the same plane as the horizontal molded part of the horizontal type, and The lower end front circumferential surface is stepped rearward to form an engagement step section that is mounted and engaged with the horizontal hook step section and has a substantially U-shaped bottom surface, and is adjacent to both horizontal short side surfaces of the engagement step section. A second stop plate for mold connection positioning, which is connected to the first stop plate for mold connection positioning of a horizontal type in an L-shape, is attached to the opposing upright side surfaces of the front surface of the front surface, In addition, a concave portion for screw fixing that opens toward the side is provided in the rear part of the upstanding side surface on both sides, and the reinforcing piece abuts the L-shape of the first and second retaining plates for positioning the mold connection. It is characterized by being formed to a desired size so as to abut against each other along the continuous outer surfaces.

<Function> According to the above configuration, the engaging stepped portion at the lower end of the vertical mold having the vertical molding portion is mounted on the locking step portion at the rear side of the horizontal mold having the horizontal molding portion. At the same time, a screw is temporarily screwed into the engaging part from within the screw fixing recess provided at the lower part of the horizontal long side surface of the locking step, thereby converting the vertical type into the horizontal locking step. Make them stand up. Then, reinforcing pieces are abutted along the outer surfaces of the first and second stop plates for mold connection positioning, which are connected in an L-shape by abutting the ends of both horizontal and vertical mold connection corners. The plates are positioned on the same plane and the horizontal mold (position) of the vertical mold is aligned with the horizontal mold. After that, screws are screwed into the reinforcing piece from inside the screw fixing recesses provided in the lower parts of the opposing upper sides of the horizontal type and the rear parts of the opposing upright sides of the vertical type, respectively. At the same time, it is fixed to the connecting corners on both sides, and the temporarily screwed screws are firmly tightened to assemble and connect both the horizontal and vertical types in an L-shape.

After forming the L-shaped unit panel, remove the reinforcing piece by loosening the screw that fixes the reinforcing piece in the screw fixing recess, and also fixing the screw that fixes the vertical type on the locking step of the horizontal type. Both the horizontal and vertical molds are disassembled in the recess, and the L-shaped unit panel is removed from the mold.
