2, the supply device 31 is retracted to the retracted position, and the vibrating device 28a installed in the table 28 on which the lower molding die 30 is placed is operated to mix with the cosmetic material Wc supplied to each molding die 30a. The seed stone S thus settled and diffused, and the seed stone S is placed on the rubber mat 29 laid on the table 28 (No.
See Figure 12 (b).

When the supply of the decorative material Wc is completed, the operating cylinder 99 of the structural material supply device 70 is extended and the moving hopper 80 containing a predetermined amount of the structural material Wd slides from the floor 98 to the upper surface of the molding lower die 30. Mounted, and the supply port 86 of the moving hopper 80 is attached to the forming die 30a.
When it reaches the row A, the moving hopper 80 is moved by the hammering device 95.
The structural material Wd in the hopper 80 is
Is supplied to each molding die 39a, and about 80% of the supply in the forward movement is supplied to the molding die 30a, and about 20% is similarly supplied by hammering in the backward movement, and at the same time, the seal member 79a is supplied. Structural material
The supply of Wd is completed (see FIG. 12 (c)).

When the supply of the structural material Wd is completed, the press device 2 is actuated to lower the slide 8 and the upper molding die 39 causes the decorative material Wc to move.
And the structural material Wd is pressure-molded (see FIG. 12 (d)). When this pressure molding is completed and the slide 8 is lifted, the lower molding die 30 also holds the pressure molding state by the supporting device and is integrally moved up together with the upper molding die 9 (see FIG. )), The pallet 100 is inserted downward from a side at a predetermined height position by a unloader such as a forklift, and only the lower molding die 30 is moved upward by the supporting device and the molded product W is demolded. It is placed on the pallet 100 and carried out (see FIGS. 12 (f) and (g)). Then, the slide 8 is moved upward, and the forming lower mold 30 is again placed on the table 28 by the supporting device (see FIG. 12 (h)), and the pavement board W is formed by repeating the above process operation. Be done.

In this way, the molding apparatus 1 of this example is constructed as described above, and the pavement board W is
Therefore, in the supply of the cosmetic material Wc, a columnar shape having elasticity of a plurality of quantifiers 36 in which each row A1 to A4 vertically provided in the supply frame 33 is used as a group unit. Container part
Since the shutters 51 and 52 of the upper and lower shutter frames 49 and 50, which are formed in a substantially lattice shape, close the predetermined height position of 37 in a flat shape, the mud-like cement used in the lower mold The shutter frame 49,5
By operating 0 to open the container portion 37, the decorative material Wc can be simultaneously supplied by its own weight. Also a distribution device
Since 54 is configured to push the decorative material Wc by the blade 66 and distribute it in a slidable manner to the container portion 37, the gap t between the blade 66 and the hole plate 34 is almost equal to the diameter of the seed stone S. The gap of about 2/3 can significantly reduce the bite of the seed stone S. The shape of the pavement board W,
The supply amount of the decorative material Wc to each molding die 30a depending on the size is changed by changing the diameter of the container portion 37 of the meter 36 or the container portion 37.
This can be dealt with by changing the height of the open / close position of the pavement board, and in particular, the change in the supply amount due to the change in the size of the pavement board W must be dealt with by changing the hole plate 34 or the number of quantifiers 36. You can Further, the position change of the molding die 30a can be dealt with by closing the mounting hole 35 of the quantification device 36 or replacing the hole plate 34 and the upper and lower shutter frames 49, 50.

Further, the supply of the structural material Wd is such that when the supply port 86 reaches the forming die 30a in the moving process of the moving hopper 80, the hammering device is operated and a predetermined amount of the structural material Wd is charged.
Since the structural material Wd is not tightened because the vibration is not applied to the hopper by the constant vibration device as in the conventional case, the unevenness of the decorative material Wc generated when it is supplied to the molding die 30a can be maintained constantly. Can be significantly reduced, and a uniform makeup layer Wc can be obtained.
The compaction is eliminated and the structural material Wd can be supplied smoothly.

Next, in the press device 2, when the slide 8 is lowered and the decorative material Wc and the structural material Wd are pressure-molded, for example, as shown in FIG.
When the slide 8 is generated, the slide 8 tends to tilt leftward, and the upper lever 14a moves counterclockwise about the shaft 11a.
The lower lever 15a tries to rotate clockwise about the shaft 13a and tries to act the link plate 17 rightward in the figure with the acting force Pa, but the upper and lower levers 14b and 15b on the right side in the figure are in a fixed state and link. A reaction force Pb equivalent to the acting force Pa acts on the plate 17 and the upper and lower levers 14a and 15a on the left side in the drawing are shown.
The slider 8 maintains the equilibrium in synchronization with the levers 14b and 15b on the right side. Further, as shown in FIG.
When an eccentric load Pa is generated near the rear part of the slide 8, the slide 8 tends to incline forward and the levers 14a, 14b and levers 15a, 15b on the front part try to rotate in predetermined directions, respectively.
Rotational moment acts on the shafts 1a, 11b and the shafts 13a, 13b, but since the rear levers 14a, 14b and the levers 15a, 15b are in a fixed state, the front levers 14a, 14b and the levers 15a, 15b are Rear levers via 11a, 11b, 13a, 13b
The slide 8 maintains the equilibrium in synchronization with 14a, 14b and the levers 15a, 15b. Therefore, since the slide 8 can maintain the equilibrium when the eccentric load Pa acts, it is possible to obtain the pavement plate W having a uniform thickness without causing unevenness in the thickness of the molded product (pavement plate). The quality can be improved. Further, since the rubber mat 29 is laid on the table 28 and the molding lower die 30 is placed, the seed stone S settled and diffused in the molding piece 30a is in contact with the rubber mat 29 when pressure molding is performed. As shown in Fig. 13, the seed stone S
Is attached to the rubber mat 29 in a biting manner, so the mat 29
The movement of water to the side can be prevented, the generation of efflorescence can be significantly reduced, and the conventional washing step can be omitted.

(Effects of the Invention) Since the present invention is configured as described above, it has the effects described below.

In the pressing device, when an eccentric load is generated on either side of the slide, the front and rear levers on the opposite side of the eccentric load act so as to synchronize with the front and rear levers on the other side via the link plate. When an eccentric load is generated either before or after, the levers that support the link plate on the opposite side of the eccentric load act in synchronization with the levers on the other side via the pair of shafts to balance the slide. Since the molded product (pavement board) is not uneven in thickness, a pavement board having a uniform thickness can be obtained and the quality can be improved. Also, since the rubber mat is laid on the table and the lower molding die is placed, when pressure molding is performed,
Since the seed stone settled and diffused in the molded piece is in contact with the rubber mat, the seed stone sticks to the rubber mat in a biting manner due to the applied pressure, so the movement of water to the mat side is blocked and efflorescence Can significantly reduce the occurrence of
The conventional washing process can be omitted.

In addition, the cosmetic material supply device flatly closes the predetermined height position of the container portion of the plurality of quantifiers in each row hung on the hole plate of the supply frame by the shutter bar of the shutter device to close the predetermined amount. Forming the receiving portion of the decorative material, the decorative material is slid into each receiving portion by pushing the decorative material by the blade of the distributing device provided on the upper part of the supply frame, and a fixed amount is distributed. When the closed state of the shutter bar is released, the decorative material of each receiving portion is dropped and supplied into the corresponding molding die by its own weight. Therefore, by setting the gap between the blade and the hole plate to be about 2/3 of the diameter of the seed stone, it is possible to significantly reduce the bite of the seed stone and the like. Since it is closed flatly, mud-like cement does not leak and the lower molding die is not contaminated. Also, changes in the amount of cosmetic material supplied to each mold depending on the shape and size of the pavement plate can be handled by changing the diameter of the container part of the metering device or the height of the opening / closing position of the container part. Especially, the change in the supply amount due to the change in the size of the pavement plate can be dealt with by changing the hole plate or increasing or decreasing the number of metering devices. Further, the position change of the molding die can be dealt with by closing the mounting hole of the metering device or replacing the hole plate and the upper and lower shutter frames.

Further, in the structural material supply device, when the supply port reaches the forming die in the process of moving the moving hopper, the hammering device is operated and a predetermined amount of the structural material is supplied. As the vibration device does not vibrate the hopper at all times, the structural material is not tightened and the dry condition can be maintained at all times. As a result, a uniform decorative layer can be obtained, and the compaction at the supply port is eliminated, so that the structural material can be smoothly supplied.
