Abstract

PURPOSE:To reduce the occurrence of efflorescence remarkably, while the molded object with uniform thickness is obtained by a method in which a slide equilibrium-keeping mechanism is provided by pivotally connecting link plates respectively between the tips of each lever of front side and rear side, and a rubber mat is put between a lower mold and a table. CONSTITUTION:In a press device, when decorative material Wc and construction material Wd are pressure-molded by lowering a slider 8, for instance, if an eccentric load Pa is generated at the right side of the slide 8, the upper and lower levers 14b, 15b of right side are fixed, and the reaction force equal to an action force Pa acts on a link plate 17, and then the upper and lower levers 14a, 15a of left side are synchronized with the levers 14b, 15b of right side, whereby the slider 8 is kept in equilibrium. Since a rubber mat 29 is laid on a table 28 and a lower mold 30 is placed thereon, seed stones S are pushed into the rubber mat 29 in close contact when pressure-molding has been achieved, therefore the transfer of moisture to the side of the mat 29 is prevented, whereby the occurrence of efflorescence may be remarkably reduced.

is stopped, and the operating cylinder 63 is shortened and inserted into the front part of the remaining decorative material WC that has been pushed.
As a result, the movable rest 57 is moved back, and the blade 66 again pushes the remaining decorative material WC and is stopped at the standby position 'e1ci. At this stop I[, the left and right operating parts 4 of the shutter device 39
The operating cylinder 46 of 0 is synchronously shortened and the upper and lower shutter frames 49.50 connected thereto are moved, and the shutter bar 51.52 that closes the container part 37 is separated from the constant hAZ36 of each row A1 to A4. The lower part of the container part 37 is opened, and the decorative material WC in the container part 37 falls and is supplied by its own weight into the mold 3Oa located below (see Fig. 12).
a)). When the supply of makeup shrine WC is completed, Bamboo moving part 4
0 operating cylinder 46 is extended and the container portion 37 is placed in the position. It is closed by the ivy par 51, 52, and the supply device 431
is returned to the retracted position, and the lower mold 30 is placed on it.
The vibrating IHff 28a installed in the table 28 is activated, and the seed stone S mixed in the decorative material WC supplied to each mold 30a is sedimented and dispersed, and the weighing stone S is shaken onto the rubber mat 29 laid on the table 28. (12th cause)
b) Reference>.

When the supply of this decorative material WC is completed, the structural material supply device H
The operating cylinder 99 of 70 is extended and moved, and the movable hopper 80 containing a predetermined amount of structural material Wd is slid from the floor 98 to the lower mold 30 E, and the movable hopper 80
When the supply port 86 reaches the eighth row of molds 30a, a hammering device 95 applies an impact to the movable hopper 80, and the structural material Wd in the small collar 80 is transferred from the supply port 86 to each mold 3.
In this forward movement, approximately 80% of the supply to the mold 30a is supplied, and in the backward movement, approximately 20% is supplied by hammering, and the seal portion 4479 decoys the mold 30a. Structural material W
(Complete the supply of ml (see Figure (C) of ml2)>.

When the supply of the structural material UWd is completed, the press device 42 is activated to lower the slide 8, and the decorative material Wc and the structural material Wd are pressure-formed by the molding upper die 9 (see FIG. 12).
d)). After this pressure molding is completed, the slide 8 is lifted up.
As the molding process progresses, the lower molding mold 30 is also moved upward together with the upper molding mold 9 while maintaining the pressure-formed state by the support device (see Figure 12 (e)), and is placed on the side at a predetermined height position. J: Rebarretsu 1-1
00 is moved downward, and here only the lower mold 30 is moved upward by the support n, and the molded product W is cut out, rolled onto a pallet 100, and carried out (FIG. 12 (fHa))
reference>. Then, the slide 8 is moved upward, and the lower mold 30 is again placed on the table 28 by the support device (see FIG. 12(h)), and the above steps are repeated to form the pavement board W. It is done.

In this way, the molded neck brace 1 of this example is constructed as described above on the pavement board W.
Therefore, in supplying the cosmetic forest WC, a plurality of elastic cylinders 36, each having groups 1 to 4, are arranged vertically on the supply frame 33 in each row. The shutter bar 51 of the upper and lower 1t ivy frame 49.50 is formed in a substantially grid shape at a predetermined height position of the shaped container portion 37.
．． 52, the shutter frame 49.50 is closed in a flat manner. By doing so and opening the container ZM37, the decorative material WC can be supplied at Fri 1 from the beginning. Also, distribution;
U54 has a configuration in which the blade 66 pushes the decorative material WC and distributes it into the container part 37 in a sliding manner.
Therefore, by setting the gap t between the blade 66 and the hole plate 34 to about 2/3 of the diameter of the seed stone S, it is possible to significantly reduce the biting of the seed stone S. . In addition, each mold 30a depends on the shape and size of the highway temporary W.
Changes in the supply amount of chemical lees lAWC can be dealt with by changing the diameter of the capacity part 37 of the dispenser 36 or by changing the diameter of the 1J11 closing position of the container part 37. Changes in the supply suspension due to changes in the size of the pavement board W can be dealt with by changing the hole plate 34 or increasing or decreasing the number of holes in the planting device 36.Also, changing the position of the mold 30a can be done by changing the hole plate 34 or increasing or decreasing the number of holes in the planting device 36. This can be solved by closing the mounting holes 35 of 36 or replacing the hole plate 34 and the upper and lower shutter frames 49 and 50.

In addition, the supply of the structural material Wd is conventionally performed because when the supply port 86 of the movable hopper 80 reaches the mold 30a during the movement process, the hammering device is activated and a predetermined amount of the structural material Wd is charged. Since the hopper is not subjected to vibration due to constant vibration vR, the structural material Wd is not tightened and is always kept in a loose state, so that the decorative material W( It is possible to reduce the deviation of I, thereby obtaining a uniform decorative layer WC, and at the same time, the compaction at the supply port 86 is eliminated, and the structural material Wd can be supplied smoothly.

Next, in the brace casing 2, when the slide 8 is lowered to pressure-form the decorative material WC and the structural material Wd, an eccentric load pa is generated on the right side of the slide 8 as shown in FIG. Then, the slide 8 (as it tries to tilt downward to the left, the upper lever 1/1a moves counterclockwise around the shaft 11a, and the 'F section lever 15a is 4m1
3 Samurai centered around a. Yt 7'Illustrated link plate 17 about to rotate in the J direction: 1j' {tJ1
However, the upper and lower levers 14b and L5b on the right side of the figure are in a fixed state and a reaction force Pb equivalent to the acting force Pa is applied to the link plays 1 and 17. The upper and lower levers 14a. 1'5a is applied to the levers 14b and 15b on the right side, and the slider 8 maintains the balance. Further, as shown in Fig. 6, for example, if the eccentric weight Pa is applied toward the rear of the slider 8, the slide 8 tends to tilt forward and downward, causing each of the levers 1 at the front. 1 4 bJ3 and lever 15a,
15b is about to move in a predetermined direction, and the shaft 11
a, 11bJ3 and shaft 13a. 13b, but the rear levers 14a, 14b and levers 15a, 15b are quickly locked, so the front levers 14a. 14bJ3 and levers 15a, 15
b are the shafts 11a, 11b, 13a. r m via 13b
RB (IQ each lever 14a, 14b and lever 15
Slide 8 maintains equilibrium in synchronization with a and 15b. Therefore, since the slide 8 can maintain equilibrium when the eccentric load Pa acts, unevenness in the thickness of the molded product (pavement board) does not occur, and it is possible to obtain a pavement board W of uniform H. Tekki quality! You can Also,
Rubber pine]・29 was laid on the table 28 and the lower mold 30 was placed on it, so when molding was performed, the molded piece 3 Q
Seed stone S & J rubber mat 29 settled and dispersed in a
Since the seed stone S is in contact with the top of the rubber mat 29, as shown in FIG. 13, the seed stone S is stuck tightly to the rubber mat 29 by the pressurizing force, thereby preventing the movement of moisture toward the mat 29 side and preventing the occurrence of efflorescence. The conventional washing process can be omitted.

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

In the case of a breather, when an eccentric load occurs on either the left or right side of the slide, the front and rear levers on the opposite side of the eccentric load act in the same way as the front and rear levers on the other side via the twist plate. In addition, if an eccentric load occurs on either the front or rear of the slide, each lever supporting the link plate on the opposite side of the eccentric load will be Since the slide can be maintained in equilibrium by this function, there will be no unevenness in the thickness of the molded product (pavement board), and pavement boards of uniform thickness can be obtained and quality can be improved. A rubber mat was laid on the table and the lower mold was attached to it, so when pressure molding was carried out, the divine stones that had settled and spread within the molded piece were in contact with the mat. The seed stone G is packed into the rubber mat by the force of 11, which prevents the movement of moisture to the mat side, significantly reducing the occurrence of dust fluoresence, and eliminating the conventional washing process. can be done.

In addition, the chemical raw material supply device n is configured such that the container portions of the plurality of evaporators in each row vertically installed on the ball plate of the supply frame are closed at predetermined positions in a flat shape by the shutter bar of the shutter device. A receiver for the decorative material of a predetermined length of h1 [the J section is shaped, and the decorative material is pushed into the shape of each receiving section by the blade of the distribution device provided on the upper part of the above-mentioned supply frame. When a fixed amount is dispensed and the shutter bar is released from the closed state, the decorative material in each receiving portion falls and is supplied into the corresponding mold by its own weight. Therefore, by setting the gap between the blade and the hole plate to about 2/3 of the diameter of the divine stone, it is possible to eliminate the possibility of the seed stone getting caught, and it is also possible to prevent the seed stone from getting caught in the container. Since it is closed in a flat shape, there is no possibility that muddy cement 1- leaks and contaminates the lower mold. In addition, changes in the supply of decorative material to each mold depending on the shape and size of the pavement board can be dealt with by changing the diameter of the container of the container or the height of the opening and closing position of the container. In particular, changes in the human nature of the pavement board and changes in its vengeance can be dealt with by changing the history of the hole play or increasing or decreasing the number of holes in the fixed skewer. In addition, changes in the position of the mold can be dealt with by closing the mounting hole of the constant feeder, or by replacing the hole plate and upper and lower shutters.

In addition, in the structural material supply system Kl, the structural material is supplied during the movement of the movable hopper, and when the supply port hits the mold, the hammering device is activated and a predetermined amount of structural material is thrown into the mold. Unlike conventional systems, the hopper is not vibrated by a constant vibrating device, so the structural materials are not tightened.
Since it is possible to maintain a dry state at all times, it is possible to significantly reduce the unevenness of the decorative material that occurs when it is supplied to the mold, and it is possible to obtain a uniform decorative layer.
This is possible because the compaction of the material is eliminated and the structural material can be fed smoothly.
