[0038] It also includes a plurality of extraction seats 8, each extraction seat 8 is fixedly installed on the top of the corresponding forming pressing plate 6, the bottom of each forming pressing plate 6 is provided with an exhaust hole 7, a one-way air outlet 9 is formed on the sidewall of each exhaust hole 7, and a connecting pipe 10 is fixedly communicated between each one-way air outlet 9 and the top of the corresponding extraction seat 8, the exhaust hole 7 is designed to use the upward movement of the forming pressing plate 6 in the forming cavity 3 when the forming pressing plate 6 is located in the forming cavity 3, so that the forming pressing plate 6 and the upper surface space of the muck filled in the forming cavity 3 generate negative pressure, then the gas in the muck is extracted, and then the gas extracted from the muck is discharged through the one-way air outlet 9 by the pressure effect of the extraction seat 8 on the connecting pipe 10, so as to complete the discharge of the gas in the muck, reduce the possibility of pores after the block is formed, and improve the quality of the block.

[0039] The sealing assembly is installed on each forming pressing plate 6 and cooperates with the corresponding one-way air outlet hole 9, and is used for controlling the communication between the one-way air outlet hole 9 and the exhaust hole 7. The sealing assembly is composed of a sealing head 11, a pull rod 12 and a pull spring 13. The sealing head 11 is sealingly and slidingly installed in the exhaust hole 7. The pull rod 12 is slidingly installed on the forming pressing plate 6, and the bottom of the pull rod 12 is located in the exhaust hole 7 and is fixedly connected with the sealing head 11. The pull spring 13 is installed between the pull rod 12 and the forming pressing plate 6. When the pull rod 12 is not subjected to upward force, the pull rod 12 keeps constant position with the forming pressing plate 6 under the action of the pull spring 13. At this time, the sealing head 11 completely shields the bottom of the exhaust hole 7, so that the problem that the slag enters the exhaust hole 7 during the pressing forming of the block can be avoided. When the pull rod 12 moves upward to make the sealing head 11 move upward in the exhaust hole 7 and make the one-way air outlet hole 9 communicate with the exhaust hole 7, the gas in the slag can be discharged outward through the one-way air outlet hole 9 at this time. The one-way air outlet hole 9 is a hole provided with a one-way valve, which can only make the gas pass through the exhaust hole 7 into the one-way air outlet hole 9 and be discharged, so that the problem that the external gas enters between the forming cavity 3 and the forming pressing plate 6 to cause the failure of the slag exhaust can be avoided.

[0040] The connecting frame 5 is provided with a suction assembly cooperating with the plurality of extraction seats 8. The suction assembly adjusts the air pressure of the connecting pipe 10 through the movement of the forming pressing plate 6.

The plurality of piston plates 21 are sealingly and slidingly installed in the corresponding extraction seats 8, and two springs are installed between the bottom of each piston plate 21 and the inner wall bottom of the extraction seat 8. The plurality of fixed rods are sealingly and slidingly installed on the corresponding extraction seats 8, and the bottom of each fixed rod is fixedly connected with the corresponding piston plate 21. The plurality of fixed rods are fixedly installed with a cross rod. Under the elastic force of the springs, when the cross rod is not subjected to upward and downward force, the position of the piston plate 21 in the extraction seat 8 can be kept constant. At this time, the pressure in the extraction seat 8 is constant, and the connecting pipe 10 cannot suck the gas into the extraction seat 8 through the one-way air outlet hole 9. When the piston plate 21 moves downward in the extraction seat 8, the connecting pipe 10 can suck the gas into the extraction seat 8. The bottom side wall of the extraction seat 8 is provided with a pressure relief hole, and the top of the extraction seat 8 is provided with a one-way air hole. The design of the one-way air hole makes the extracted gas be discharged outward in one direction when the piston plate 21 moves upward in the extraction seat 8, and the external gas cannot be sucked into the extraction seat 8 through the one-way air hole when the piston plate 21 moves downward in the extraction seat 8, so that the suction and discharge effect of the one-way air outlet hole 9 on the gas in the slag is ensured. The design of the pressure relief hole can ensure the constant pressure at the bottom of the extraction seat 8.

[0041] The connecting frame 5 is composed of a fixed plate and a plurality of fixed columns fixedly installed on the bottom of the fixed plate, the top of each forming pressing plate 6 is fixedly connected with the corresponding plurality of fixed columns respectively, and the fixed plate and the plurality of fixed columns are not in contact with the cross bar, two magnetic blocks 23 are fixedly installed on the side wall of the forming die 2, and the two ends of the cross bar are respectively fixedly installed with side metal columns 22 opposite to the positions of the corresponding magnetic blocks 23, the attraction of the magnetic blocks 23 to the side metal columns 22 is greater than the elastic force of the springs through regulation and control, when the hydraulic cylinder 4 is started to make the forming pressing plate 6 enter the forming cavity 3 (as shown in the state of Figure 1 ), at this time, the side metal columns 22 are moved downward under the action of the attraction of the magnetic blocks 23, and the cross bar is kept in the same position relative to the forming die 2 under the action of the attraction, then the hydraulic cylinder 4 is made to perform reciprocating extension and contraction within a certain range, specifically, the forming pressing plate 6 is not in contact with the upper surface of the slag soil and there is a certain gap between the forming pressing plate 6 and the upper surface of the slag soil when the forming pressing plate 6 moves downward in the forming cavity 3, and the distance of the gap is 5 cm, and the forming pressing plate 6 is not separated from the forming cavity 3 when the forming pressing plate 6 moves upward in the forming cavity 3, when the forming pressing plate 6 moves up and down within the moving range, the upward movement of the forming pressing plate 6 will make the cross bar move downward relative to the forming pressing plate 6, at this time, the plurality of piston plates 21 can be simultaneously moved downward in the corresponding extraction seats 8, so that the connecting pipe 10 generates negative pressure, providing power for the extraction of gas in the slag soil.

[0042] A plurality of same-direction differential assemblies are installed on the forming die 2, and each same-direction differential assembly is matched with the corresponding plugging assembly, the same-direction differential assembly controls the operation of the plugging assembly through the upward and downward movement of the forming pressing plate 6, the same-direction differential assembly is composed of a rack one 14, a rotating shaft 15, a one-way bearing 16, a gear one 17, a gear ring one 18, a connecting shaft, a gear ring two 19 and a rack two 20, the rack one 14 is fixedly installed on the side wall of the pull rod 12, the rotating shaft 15 and the connecting shaft are both rotatably installed on the side wall of the forming die 2, the gear one 17 is installed on the rotating shaft 15 through the one-way bearing 16, and the gear one 17 is engaged with the rack one 14, the gear ring one 18 is fixedly installed on the rotating shaft 15, the gear ring two 19 is fixedly installed on the connecting shaft, and the gear ring two 19 is engaged with the gear ring one 18, the rack two 20 is fixedly installed on the side wall of the forming pressing plate 6, and the rack two 20 is engaged with the end of the gear ring two 19 away from the gear ring one 18, as Figure 6As shown, the design of the one-way bearing 16, when the rotating shaft 15 rotates clockwise, can drive the gear one 17 to rotate clockwise at the same time, at this time the meshing effect of the gear one 17 and the gear rack one 14 drives it to move up, and when the rotating shaft 15 rotates counterclockwise, the one-way bearing 16 is in a rotating state, at this time the rotating shaft 15 rotates without driving the gear one 17 to rotate, so the up and down movement of the gear rack one 14 is not affected by the rotation of the rotating shaft 15, then when the forming pressing plate 6 moves up and down on the forming mold 2, the gear rack two 20 moves down to drive the gear ring two 19 to rotate clockwise, at this time the meshing of the gear ring two 19 and the gear ring one 18 makes the rotating shaft 15 rotate counterclockwise, at this time the gear rack one 14 is not affected by the rotation of the rotating shaft 15, and when the forming pressing plate 6 moves up, the gear rack two 20 drives the gear ring two 19 to rotate counterclockwise, so the rotating shaft 15 will rotate counterclockwise at the same time, at this time the gear rack one 14 moves up under the pushing action of the gear one 17;

[0043] The diameter of the gear one 17 is greater than the diameter of the gear ring two 19, and the diameter of the gear ring two 19 is greater than the diameter of the gear ring one 18, through the design of the size here, when the forming pressing plate 6 moves up to drive the gear rack two 20 to move up, it can make the gear rack one 14 move up at a faster amplitude, so that the pull rod 12 can move up a greater distance, so that the head 11 can move up in the forming pressing plate 6 to open the exhaust hole 7, because negative pressure will be generated in the extraction seat 8 during the upward movement of the forming pressing plate 6, therefore when the exhaust hole 7 is opened, the gas located at the bottom of the forming pressing plate 6 will be discharged through the one-way exhaust hole 9, and when the forming pressing plate 6 moves up in the forming cavity 3, a negative pressure will also be formed between its bottom and the back of the slag, which can extract the gas in the slag, and then when the exhaust hole 7 is opened, the extracted gas can be directly discharged, adjusting the capacity of the extraction seat 8, so that the pressure change generated by the movement of the piston plate 21 in the extraction seat 8 is greater than the pressure change generated by the movement of the forming pressing plate 6 in the forming cavity 3, then the effective discharge of the gas can be always maintained, avoiding the problem that when the pressure in the forming cavity 3 is negative, the gas cannot be discharged.

[0044] The installation plate 24 is slidably installed on the forming die 2, and a plurality of stirring assemblies matched with the corresponding forming cavities 3 are installed on the installation plate 24, and the stirring assemblies are used for stirring the slag in the forming cavities 3, and the stirring assemblies are composed of a rotating rod 25, a stirring blade 26 and a movable sealing piece 27, the rotating rod 25 is rotatably installed on the installation plate 24, the stirring blade 26 is fixedly installed on one end of the rotating rod 25 away from the installation plate 24, and the length of the stirring blade 26 is less than or equal to the length of the lead screw 35, the movable sealing piece 27 is rotatably installed on the rotating rod 25 through a damping bearing, the side wall of the forming cavity 3 is provided with a through groove 28 matched with the stirring blade 26 and the movable sealing piece 27, the side wall of the one end of the rotating rod 25 away from the stirring blade 26 is fixedly installed with a positioning ring, the installation plate 24 is provided with an annular positioning groove matched with the positioning ring, the side wall of the rotating rod 25 is fixedly installed with a gear ring three 29, a plurality of gear racks three 30 are fixedly installed on the side wall of the connecting frame 5, and each gear rack three 30 is matched with the corresponding stirring assembly and the knocking vibration assembly, when the slag is discharged, the rotation of the stirring blade 26 driven by the rotating rod 25 can stir the slag, so that the components of the slag can be more uniformly distributed in the forming cavity 3, and it is also helpful for the discharge of the gas in the slag, and the design of the movable sealing piece 27 can keep the sealing effect of the side wall of the forming cavity 3 while the stirring blade 26 stirs the slag driven by the rotating rod 25, so as to avoid the problems of slag overflow or external gas entering the forming cavity 3, the gear ring three 29 is engaged with the gear rack three 30, and when the connecting frame 5 moves up and down, the rotating rod 25 can be driven to rotate, so that the stirring process can be directly driven without additional power equipment, and the production cost can be reduced.
