The chamber application side of the present invention will be explained by taking as an example a thick straight molding method and a method for taking it out.

FIG. 1 shows a press mold 2 attached to the lower end of a piston rod 1 of a hydraulic cylinder (not shown) via a press mold fitting 1a, and a press mold 2 that surrounds the press mold 2 and is attached to the press mold 2 in a vertical movement position. A predetermined amount of mortar 6 placed on the receiving mold 5 is surrounded by the side mold 3 and the receiving mold 5 placed on the base 4,
This figure shows how the piston rod 1 is lowered while giving vertical vibrations to the piston rod 1 by the above-mentioned oil pressure movement of the not-illustrated hydraulic cylinder, and the mortar 6 is formed into a shape. To explain the above-mentioned forming method in more detail including the removal method, the base 4 is removably attached to a traveling base 7 which is not shown in the drawings and is configured to move left and right on a guide rail. Further, a fluid pressure cylinder 8 is attached to 7 on the right side of the base 4, and its piston rod 9
The piston rod 1 is raised from the position shown in the figure, in which a molded product receiving stand 11 to which an elastic body 10 made of soft urethane foam or foamed rubber is attached is attached to the upper end, and the traveling table 7 is moved to the left. The explanation will be made starting from the position where the receiving stand 11 is positioned directly below the pressing mold 2. At this time, the mold 5 and mortar 6 are not placed on the base 4. First, place the base 4 on the base 4.
A receiving mold 5 having a lower surface that is in close contact with the upper surface of the mold is placed, and a predetermined amount of mortar 6 is placed on the receiving mold 5 using a meter. Next, move the traveling table 7 to the right side and press the base 4 with the press mold 2.
, lower the piston rod 1 to align the side mold 3 with the base 4, surround the mortar 6 with the receiving mold 5, the side mold 3, and the pressing mold 2, and lower the piston rod 1 while lowering the piston rod. Vertical vibration is applied to the piston rod 1, the pressing mold 2 is lowered, the mortar 6 is formed into the mold, and the vertical vibration and lowering of the piston rod 1 are stopped. The piston rod 1 may be positioned at the lowest end of its downward stroke to stop its vertical vibration and descent, or the vertical vibration is applied only during the middle stroke of the descent, and at the end the vertical vibration is stopped and the piston rod is pressed only by the downward force. may be formed. When molding is finished, the piston rod 1 is raised to raise the molded product together with the pressing mold 2 and side mold 3 with the receiving mold 5 still attached, and the traveling table 7 is moved to the left to move the receiving table 11 to the pressing mold 2. The elastic body 1 is positioned directly below and the receiving table 11 is raised.
0, lightly press the receiving mold 5 to support the receiving mold 5 with the receiving allowance 11, and raise the side mold 3 to open the side surface of the molded product, or further lower only the pressing mold division piece 2a slightly. to push down the molded product and raise the piston rod 1 or
1 is lowered, the molded product is transferred onto the elastic body 10 together with the receiving mold 5. Note that other known techniques can be used to peel off the side and top surfaces of the molded product. Next, the side mold 3 is lowered to prepare for molding, but during the above operation, the receiving mold 5 and the mortar 6 are placed on the base 4, and the traveling base 7 moves to the right and the base 4 is placed on the base 4. When the piston rod 1 is located directly below the press mold 2, the piston rod 1 is lowered and molding begins. On the other hand, at this time, the molded product on the elastic body is taken out together with the receiving mold 5 and placed on a shelf. By modifying the above operation (1), thick slate molding and molded product removal are performed continuously. In preparation for molding, prior to the lowering of the side mold 3, the pressing mold segment 2a rises and returns to the previous position (2). Further, the lower end of the side mold 3 is sloped from the outside toward the inside, so that the position of the receiving mold 5 placed on the base 4 can be corrected.

In the above method, it is desirable to use a lightweight mold made of synthetic resin or the like as the mold 5. If the weight of the receiving mold 5 is large, there is a possibility that the receiving mold 5 will remain on the base 4 when the molded product is lifted, but as shown in FIG. Accordingly, a drawer 12 is provided to control the inside of the moving room.
During molding, when lowering the piston rod 1 to fit the side mold 3 to the base 4, the drawer 12 is retracted, and when the molded product is to be raised, the drawer 12 is protruded and the receiving mold 5 is closed. The receiving mold 5 can be supported by tapping (2) and raised together with the molded product.

When the side mold 3 is provided with the protrusion 12, a concave part for the protrusion 12 is formed on the side line portion of the upper surface of the base 4.

Figure 3 shows another molding method and extraction method, in which the receiving plate 5' is attached to the base 4.
The device differs from the device shown in Fig. 1 in that the side die 3' is wider than the upper surface of the mold, and the side mold 3' is provided with a concave part 12, and the upper surface of the base 4' is not provided with a concave part. The thick slate is formed and the molded product is removed in accordance with the molding method and removal method described in FIGS. 1 and 2, so a detailed explanation will be omitted.

FIG. 4 shows that an impact casing 14 is movably attached to the lower part of a piston rod 13 of a hydraulic cylinder (not shown), and a pressing die 15 detachably attached to the impact casing 14 is mounted on a base 16. The mortar 19 on the receiving mold 17 is surrounded by the placed receiving mold 17 and the side mold 18 which is attached to the base 16 so as to be able to move up and down. The piston rod 13 is lowered while applying vibration, and mortar 19 is pressed and formed while applying an impact to the bottom of the impact casing due to the vertical vibration of the piston rod 13. Furthermore, the piston rod 13 has a stopper 1 on its outer circumference.
3a is fixed to the inner wall of the impact casing 14 so that it can move freely, and the impact casing 14 has a moving cylinder 14a formed or inserted therein. It is free to move. Also, an end bracket 14 is attached to the upper end of the impact casing 14.
b is formed, and when the piston rod 13 is raised, the end bracket 14b is hung on the stopper 13a and the impact casing 14 is also raised, and the piston rod 13 is lowered so that the pressing mold 15 comes into contact with the mortar 19, and the pressing mold 15
When the downward movement of the mortar 19 stops, only the piston rod 13 descends while vibrating up and down, applying an impact to the bottom 14c of the impact casing 14, and the piston rod 13 is lowered while applying the impact to press-form the mortar 19. ing.

For the above reason, an impact chamber 20 is formed below the piston rod 13. The impact can be applied by the piston rod 13 by directly hitting the bottom 14c of the impact casing 14 with the lower end of the piston rod 13.
A cushioning material such as a lead plate, sand, metal powder, or wood powder may be provided on the surface of c, and the material may be hammered through the cushioning material. Further, a passage hole communicating with the impact chamber 20 can be provided in the impact casing 14 or the piston rod 13 so that the impact casing 14 does not rise due to vibration during press molding. When no ventilation hole is provided, the air in the impact chamber 20 is sealed, and the bottom 14c of the impact casing 14 is moved by the piston rod 13 through the air.
Due to the force of the compressed air, the impact casing 14 does not rise due to vertical vibration during press forming, and less noise is generated.

Further, the shock chamber 20 can be filled with a liquid such as oil. At this time, the impact casing 14 above the liquid level can provide a ventilation hole in the piston rod 13 so as not to create a vacuum between the liquid and the piston rod. In addition, as shown in the figure, if the piston rod 13 is provided with an unpierced joint hole 21 that communicates with the shock chamber 20, or if compressed air is introduced into the joint hole 21 (a horizontal hole 22 that communicates with the joint hole 21 is provided, A pipe 24 with a valve 23 is fixed to the pipe 24, and compressed air can be sent into the joint hole 21 by a compressor through the pipe 24.) To prevent the impact casing 14 from rising due to vertical vibration during press molding. and piston rod 1
3 hits the bottom 14c of the impact casing 14 through the liquid in the impact chamber 20, so no noise is produced. The above-mentioned joint hole 21 may be provided in the moving tube 14a.
It can also be replaced by Also, put liquid in the shock chamber 20,
A slight air layer may be provided above it, and an impact may be applied through the air and liquid.

Next, a molding method and a take-out method using the apparatus shown in FIG. 4 will be explained. First, the side mold 18 is raised as shown in the figure, and the receiving mold 17 is placed on the base 16.

Next, mortar 19 is placed on the receiving mold 17 using a metering machine (not shown). At this time, the pressing die 15 is rising. Next, the piston rod 13 is lowered, and the hydraulic pressure of the hydraulic cylinder is moved from an appropriate position to give vertical vibration to the piston rod 13 while lowering the piston rod 13.
While the lower end of the piston rod 13 applies an impact to the bottom 14c of the impact casing 14, the pressing die 15 descends to press-form the mortar 19. When the molding is finished, the lowering of the piston rod 13 and the vertical vibration are stopped, and the piston rod 13 is raised while sucking the receiving mold 17 to the base 16 using the vacuum suction hole 25 of the base 16, and the pressing mold 15 is moved upward. Peel off the bottom surface and the top surface of the molded product. Next, release the vacuum suction and remove the side mold 18.
is lowered to separate the side surface of the molded product and the side mold 18,
The push-up cup 26 is raised to raise the receiving mold 17 on which the molded product is placed, and then it is taken out and placed on a shelf. Molding and removal are performed continuously by repeating steam operation.

The device shown in FIG. 5 differs from the device shown in FIG. 4 in that a side mold 18' is provided so as to be movable up and down around a pressing mold 15' attached to the impact casing 14. To explain the molding method and take-out method using the device shown in Fig. 5, first the base 1
A receiving mold 17' is placed on the mold 6, and mortar 19 is placed thereon using a metering machine. At this time, the pressing die 15' and the side die 18
' is rising. Next, the side mold 18' and the pressing mold 15' are lowered to surround the mortar 19, and while only the pressing mold 15' is lowered, the hydraulic pressure of the hydraulic cylinder is moved to give vertical vibration to the piston rod 13, and the impact The piston rod 13 is lowered while applying an impact to the bottom 14c of the casing 14, and the mortar 19 is press-molded. After the molding is completed, the receiving mold 17' is sucked onto the base 16 using the vacuum suction hole 25, the side mold 18' is raised to separate it from the side of the molded product, and then the molded product is pressed together with the side mold 18'. The mold 15' is raised to separate the upper surface of the molded product from the lower surface of the pressing mold. Next, the vacuum suction is released, the push-up cup 26 is raised, and the receiving mold 17' with the molded product placed thereon is taken out and placed on a shelf. By repeating the above body movements, molding and unloading are performed continuously and automatically.

We have described many examples of thick slate molding methods and molded product extraction methods with reference to Figures 1 to 5 above. It is desirable to install the press mold in such a way that the vertical vibration or impact force applied to the press mold during press molding is not transmitted to the side mold, and one method is to separately provide a lifting device for the side mold and a lifting device for the press mold. In addition, in FIGS. 1 and 3, instead of the vibrating device A consisting of the piston rod 1 and the press-type fitting 1a, it consists of the piston rod 13, stopper 13a, and impact casing 14 explained in FIGS. 4 and 5. Pressure molding may be performed while applying impact using impact device B, and in Figures 4 and 5, vibration device A may be used in place of impact device B to perform press molding while applying vibration. Needless to say. Further, an elastic layer made of rubber or the like can be interposed between the base and the mold by being fixed to the base or the mold.

FIG. 6 shows another example of the impact device, and the impact device B' includes a hydraulic cylinder (not shown), its piston rod 27,
It is composed of a stopper 28 firmly fixed to the piston rod 27, an impact sheath 29 movably attached to the piston rod 27, a spring 30 provided within the impact casing 29, and a liquid 31 such as oil. . The impact casing 29 is attached to the end bracket 29a.
, a base 29b, and an outer cylinder 29c are assembled with bolts, and the end bracket 29a and the rod guide 29a formed on the base 29b are movable on the piston rod 27, and are connected to the lower end of the piston rod 27 and the rod guide 29a. A shock chamber 32 is formed by the guide 29a. Further, the rod guide 29a is provided with an intake/exhaust hole 33 in its wall, and the outer cylinder 29c is provided with a ventilation hole 34. Note that 35 is a pressing die attached to the impact device B' with bolts. In the apparatus of FIGS. 1 and 3 to 5, an impact device B' can be used in place of the vibration device A and the total force device B. That is, when pressing the mortar by lowering the piston rod 27 while applying vertical vibration to the piston rod 27 by moving the pressure oil in the hydraulic cylinder, the liquid 31 in the shock chamber 32 when the piston rod descends during the vertical vibration. is discharged from the suction/discharge hole 33 to the lot guide 2.
9a, and the lower end of the piston rod 27 is in the suction/discharge hole 3.
3 is closed, the liquid 31 is discharged upward and an impact is applied to the pressing die 35. When the piston rod rises, the liquid 31 in the outer cylinder 29c flows into the rod guide 29a from the suction/discharge hole 33, and the stopper 28 presses the base 29b via the spring 30, so the impact casing 29 does not rise. First, an impact can be applied to the base 29b by the piston rod 27 via the liquid 31, and this can be transmitted to the pressing die 35. Therefore, good press molding can be performed with less noise. In the above-mentioned impact device B', as shown by the dotted line, a communication hole 36 communicating with the liquid in the outer cylinder 29c outside the impact chamber 32 is provided below the suction and exhaust hole 33 of the base 29b or the rod guide 29a. If a valve 37 is provided in this and configured so that the valve opens when the piston rod 27 rises and closes when the piston rod 27 falls when the piston rod 27 vibrates vertically, the spring 30 is not necessarily Not necessary.

When the piston rod stops vibrating up and down and descending, the tapping cup 50 that had been retracted into the side die 49 is projected and aligned with the lower surface of the receiving die 43, and the press die 51, side die 49, and tapping cup 50 are used to form a molded product. and supports the receiving mold 43 to raise the piston rod. Incidentally, FIG. 9 shows the state upon completion of molding. Next, move the carriage 40 to the left side, position the receiving stand 47 directly below the pressing mold 51, raise the pilton rod 45, lightly support the receiving mold 43 with the elastic body 48, and retract the tapping cup 50 to the side. By lifting the mold 49, the molded product and the side mold 49 are separated. When only the pressing die division piece 51a is slightly lowered to push down the molded product, the molded product is soft transferred onto the elastic body 48. Next, the piston rod 45 is lowered and the pressing type divided piece 51a
is raised to return to the old position, and the side mold 49 is lowered to prepare for the next molding. During this operation, mortar 43 is being formed on base 41.

During molding, if the pressing mold division piece 63a is lowered as shown by the dotted line so that its lower surface is on the same surface as the pressing mold 63, pressing molding can be performed twice with the same pressing mold, and one pressing mold can be formed. That's enough. In the figure, 64 is a hole that fits into the hole mold 57. The above method is effective for forming an uneven pattern on the inner surface of the side mold 56 and using a surface-molding mortar on the surface of the molded product, but when the surface-molding mortar is not used, There is no need for press molding, and after the first press molding and side peeling, the molded product can be lifted up together with the receiving mold and taken out. Further, the hole mold 57 may be attached to the base 58 so as to be freely drawn out.

Above, we have explained many examples of forming and extracting methods for thick slate and perforated concrete blocks, but the first, third, fourth, fifth,
The press forming shown in FIGS. 7, 9, and 10 to 14 may be performed by applying pressure while applying vibration or impact (blow), or without applying vibration or impact. When performing press molding while applying an impact, any of the impact devices described in the present invention may be used. In addition, as shown in Figures 1, 3, 7, and 9, when the receiving mold and the molded product are raised together with the pressing mold, the pressing mold is not provided with a pressing mold dividing piece, but is provided with many vacuum suction holes, and the mortar is pressed. A wire mesh and dewatering cloth are interposed between the molds to press and mold the mortar while squeezing water, and a suction device creates an air flow to discharge the water from the vacuum suction hole to the outside, and when the press mold is raised, vacuum suction is applied. The release of the molded product can be improved by releasing the pressure or by pumping air. Moreover, a spring may be interposed between the receiving stand and the piston rod without attaching an elastic body thereon. In addition, the mortar used in the examples has a water-cement ratio of about 45% when water is squeezed, but by adding a thickener or a water-reducing agent to this, the water-cement ratio can be reduced to 25%.
There is no need to squeeze water if it is about ~35%. 1st, 3rd,
The mortar used in Figures 4 and 5 is a mortar with a low water-cement ratio and good properties, and the mortar used in Figures 7 and 9 and 10 to 14 is a loose mortar with a low water-cement ratio. good. The metering supply device consisting of the base 41 including the metering box 39 and the side mold 42 shown in FIG. 7 can be used in other embodiments as well. The molding method and extraction method of this invention can be used not only for thick slate and perforated concrete blocks, but also for molding and extracting clay roof tiles, tiles, stones, etc. as described above, and the mortar used in the examples is raw materials such as concrete, soil, etc. The present invention can also be used in powder metallurgy, and can also be used in die casting of aluminum or zinc, that is, molding of molten metal. Forming these metals requires heating and cooling. In addition, in this invention, raw materials such as mortar were placed on one mold using a metering machine, etc., and then surrounded by another mold and pressure-molded. Configure a sealed chamber with a mold,
Using a nozzle in a closed room, you can mix powders, granules, or crushed pieces with liquids such as water, molten metal, and binders, and liquids such as synthetic resins and molten metals that harden by heating or cooling (two-liquid). Alternatively, a material to be molded, that is, a raw material made of a mixture thereof, may be fed under pressure, and the material may be press-molded while applying impact. If it is to be hardened by heating or cooling after molding and then taken out, it may be remolded by semi-hardening or by pressing again while applying an impact after hardening.

This method can be used in manufacturing die-cast products, powder metallurgy, injection molding of synthetic resins, etc. When manufacturing die-cast products, molten metal is press-formed while applying impact using an impact device, and molding is performed in a semi-hardened or hardened mold using the above-mentioned impact device or another impact device. The product may be pressed and molded while applying impact. It goes without saying that the molten metal may be molded by a conventional manufacturing method, and the semi-cured or hardened molded product in the mold may be pressed and re-molded while applying an impact. Therefore, as the mold used for manufacturing the above-mentioned die-cast product, a pressing mold as explained in the embodiment can be used, and the pressing function can be achieved by moving it with other molds. The number of molds other than the pressing mold may be one or more. Also, when manufacturing ultra-solid metal die-cast products such as aluminum and zinc, the product is rapidly cooled in the mold or after demolding.

By using the molding method and take-out method of the present invention, it is easy to mold and take out the casting, and ceramic or the like can be used for the mold.

Furthermore, when press molding thick slate or the like, it is possible to perform surface molding with a receiving mold and to perform back molding with a pressing mold. At this time, a surface coating agent such as ■ or cement synthetic resin mixed with pigments is applied to the receiving mold or further to the side mold, and raw materials such as mortar are applied to this and laminated and integrally press-molded. It's fine. Needless to say, pressure molding may be performed while applying vibration or shock during pressing.

In addition, the materials to be molded, that is, the molding raw materials, include a blast furnace, cement, gypsum, and one or two of the following binders.
Mixtures containing more than one type of aggregate, or even a refractory aggregate, can be used.

Sho blast furnace■ is a general term for water■ and slow cooling■, and binder is water glass or its aqueous solution, cellulose thickener aqueous solution, glue aqueous solution, seaweed-based glue or its aqueous solution, synthetic resin emulsion, synthetic rubber. A general term for emulsions that have the property of fixing substances, such as emulsions or mixtures thereof. In addition, heat-resistant aggregate is a general term for heat-resistant aggregates such as igneous rocks such as andesite and basalt, whitebait, lava rock, mineral chamotte, artificial aggregates expanded by heating, pumice, perlite, and pottery waste. .

The above raw materials are press-molded with or without adding water and with or without applying vibration or impact.

Example 1 50 parts by weight of Portland cement, 150 parts by weight of water,
A mixture of 100 parts by weight of heat-resistant aggregate and an appropriate amount of water is molded and taken out to obtain a heat-resistant thick slate.

Example 2 A mixture of 100 parts by weight of blast furnace cement, 100 parts by weight of water, 100 parts by weight of heat-resistant aggregate, and an appropriate amount of water was molded and taken out to obtain a heat-resistant thick slate.

As the molding method and take-out method in the above two embodiments, many of the above-described molding methods and take-out methods can be used. The heat-resistant thick slate described above can be prepared by coating the surface or the entire surface with an inorganic paint or heating it to a temperature at which the inorganic paint melts or hardens, for example 1000°C, and then rapidly cooling it, or further humidifying and heating it. It goes without saying that it may be heated to a temperature at which the inorganic paint melts or hardens, for example 1000°C, and then slowly cooled. It goes without saying that heating or water-added heat curing may be applied. The method for producing thick slate described above can be used for concrete blocks, concrete pavement boards, interlocking blocks, etc., and various heat-resistant concrete products coated with (1) and inorganic paints can be obtained.

In addition, the base material raw material and the heat-resistant surface molding raw material are layered with or without a heat-insulating raw material layer, pressure molded with or without applying vibration or shock, and the surface is coated with ■ or inorganic paint, and only the surface is formed. may be heated.
