JP 54-5105823 Already Provided by the Patent Applicant
The panel 20 according to this issue has a large number of small blocks 21, and... is a deep V-shaped split joint 23 interposed between each small block.
A weak joint 22 formed at the bottom of the split joint and surrounded by
are interconnected. Such a panel 20 has a wide variety of designs and patterns such as the size, shape, arrangement, etc. of the small blocks 21, depending on the purpose, place of use, fashion, user preference, etc. A mold with a structure suitable for each different design and pattern was required, and as a result, a mold with a structure suitable for each type of formwork had to be ordered each time. As is known, the production cost of molds is extremely high, and preparing multiple types of molds depending on the type of formwork is a huge cost burden for panel manufacturers. Since there was no compatibility, a new mold had to be made each time even a partial design change was made, which inevitably made the panels expensive. In order to eliminate the above-mentioned drawbacks, the present invention is characterized in that the mold structure can be assembled in a wide variety of ways according to changes in the pattern and design of the frame mold. The object of the present invention is to provide a formwork forming method and a mold thereof, in which a large number of unit molds are installed in an internal space in a fixed arrangement pattern, and a set of unit molds can be used to form an arbitrary pattern of formwork. do.

The present invention will be described below based on an illustrated embodiment. Reference numeral 1 denotes a mold for forming a molding frame 2 for forming a panel as described above, and the mold 1 includes a frame mold 3 surrounded by a frame wall 11 and a former JV.
") It consists of a set of a large number of separate and independent unit molds 4 which are inserted into the internal space 3 of the frame mold 3 for molding a block group.

The unit mold 4 has a bottom wall 5 for molding the surface shape of the small block.
and a peripheral wall 6 rising from the periphery of the bottom wall 5. The unit molding chamber 4' molds each small block molding chamber 17 of the formwork 2. The unit molding chamber 4' has a generally concave cross section with an open top. Each unit mold 4 has an inner peripheral surface of the peripheral wall 6 raised from the periphery of its bottom wall as a sloped wall surface 6a, and the peripheral wall of each unit mold 4 is formed by the sloped wall surface 6a and the inner bottom surface 5a of the bottom wall. The outer peripheral surface of the unit mold 4 is made a vertical wall surface 6b, and the peripheral wall 6 of each of the unit molds 4 is brought into close contact with the vertical wall surface 6b of the adjacent unit mold peripheral wall 6 using the vertical wall surface 6b. A joint partition wall 8 having a substantially inverted V-shape in cross section and partitioning the adjacent unit molding chambers.
The joint partition wall 8 is brought into close contact with the inner surface of the frame wall 11 at a position where the top portion 9 does not reach the upper end of the frame wall 11, and a frame wall is formed between the joint partition wall 8 and the upper part of the unit molding chamber 4'. A connecting portion molding chamber 12 surrounded by an upper portion is formed. The joint partition wall 8 is the formwork 2
The joint molding portion 19 is molded. The joint partition wall 8 forms various patterns of joints by continuous ridge lines depending on the combination of the unit mold groups 4, . . . . Ru. Another example includes a case in which the top portion 9 of the joint partition wall 8 is not sharp but has a flat surface. In either case, since the separation line portion of each unit mold 4, . As an example, the unit mold 4 is a square-shaped mold, and a standard unit mold whose vertical and horizontal lengths are constant dimensions is set, and the size of the unit mold 4 is always set to the standard unit mold. Set to multiple dimensions.

A mold is formed by a combination of the standard unit mold and the proportional multiple unit mold, or a set of either one of them. In this case, each unit mold 4, . It can be adapted to a mold of any size, and has the power to rearrange and change molds of any size, and can be assembled into a small project that can be freely spaced by incorporating several types of unit molds 4,... Patterns and joint patterns can be formed, making recombination easy. According to this, it is possible to provide a formwork for molding many types of panels, which are rectangular panels having a uniform size, but having different internal small block arrangements and joint deformations. The unit mold 4 has an inner bottom surface 5a of its bottom wall 5 in an arbitrary shape depending on the implementation, and molds a mold 2 having a surface corresponding to the shape. Each of the unit molds 4, .
. . , the movement of the unit molds 4 and the frame mold 3 constitute one continuous mold. Further, the frame mold 3 is provided with a flange molding part 10 extending over the entire area of the frame wall 11 at the upper end of the frame wall 11, and is connected to the integral continuous molding mold to mold the flange part 18 of the frame 2. Note that 13 in the figure is a vacuum hole for vacuum forming. 5 and 6 show other embodiments of the unit mold. As shown in FIG. A decorative joint molding portion 14 is formed to be joined to the inclined wall surface 6a of the peripheral wall 6.

The decorative joint molding section 14 is a decorative joint molding section 16 of the formwork 2.
mold. Further, as shown in FIG. 6, the bottom wall 5 is formed with an uneven surface 15 to express a stone pattern or the like, giving a decorative effect similar to that of natural stone. The mold 1 incorporates a large number of unit molds 4 all over the interior space 3' of the frame mold 3, and makes the molds 4 in close contact with each other to form a mold with a certain combination pattern. Each unit mold 4 is placed in close contact with the frame wall 11 of the mold 3 to regulate its position without any movement, and each unit mold 4,...
The mold 1 in which the joint partition wall 8 is integrally formed is constructed by the close contact between the two.

In this case, if the frame mold 3 has a bottom as shown in FIG.
Each of the unit molds 4, . A molten synthetic resin material is supplied to the upper surface of the mold 1, and the vacuum holes 13,...
A synthetic resin mold frame 2 in the form of an integral sheet or integral film having a shape corresponding to the pattern of the mold is formed by suction from the mold. Note that the mold 1 can also be used in other pressure molding methods or press molding methods. According to the present invention, by using a frame mold as a reference and incorporating a large number of unit molds into the internal space of the frame mold to construct a mold with a desired pattern, it is possible to perform form molding with a large amount of force. .

In other words, various designs, shapes,
It is possible to arbitrarily combine unit molds of any size, and by combining the unit molds, it is possible to arbitrarily configure the arrangement pattern of small blocks and the joint pattern to form panel molding forms of various designs. It has the advantage of being able to produce molds with a wide variety of designs by partially replacing the unit mold, or by recombining or partially changing the mold without having to remake the entire mold, and can be manufactured at an extremely low cost. , can flexibly respond to user requests. In addition, the cost of molding can be greatly reduced, and not only the cost of molding but also the manufacturing price of panels can be significantly reduced, making it possible to mass-produce various types of panels.
