[0001] The invention relates to the technical field of concrete block production, and mainly proposes a forming device for producing concrete composite blocks. Background Art

[0002] Concrete composite blocks are a commonly used building material, usually made by mixing concrete, fine aggregate, coarse aggregate, water and additional materials. Concrete composite blocks are widely used in civil and commercial buildings because of their high compressive strength and corrosion resistance.

[0003] Concrete composite blocks are generally made using molds. Concrete slurry and additional materials are first mixed, and then the mixed concrete block raw materials are introduced into the mold. After a period of time, the concrete block raw materials solidify into concrete composite blocks. However, during the production of existing concrete composite blocks, the block raw materials are often continuously injected into the mold at a fixed position. Due to the insufficient fluidity and high viscosity of the block raw materials, the block raw materials cannot fit the mold well, and air bubble cavities will be formed in the corners of the mold, resulting in reduced integrity of the concrete composite blocks.

DETAILED DESCRIPTION

[0021] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0022] Example 1: A forming device for producing concrete composite blocks, see Figure 1 , Figure 2 and Figure 4-Figure 6, including: a frame 1, on which a lower hopper 2 is installed; a mounting shell 3, which is slidably connected to the frame 1, and a first electric push rod 4 is installed on the frame 1, and the telescopic end of the first electric push rod 4 is fixedly connected to the mounting shell 3, and a block mold 5 is arranged below the mounting shell 3; a plurality of second electric push rods 6 are all installed in the mounting shell 3, and the telescopic ends of all the second electric push rods 6 are commonly fixedly connected to a mounting frame 7, and the mounting frame 7 is installed with an electric rotating rod 8, and a reciprocating thread is arranged on the electric rotating rod 8, and the electric rotating rod 8 is threadedly connected to a connecting shell 9, and the connecting shell 9 is rotatably connected to a material guide shell 10, and a material conveying pipe passing through the mounting shell 3 is connected between the discharge port of the lower hopper 2 and the connecting shell 9, and a connecting pipe is connected between the connecting shell 9 and the material guide shell 10, and the length of the lower side outlet of the material guide shell 10 is greater than the length of the upper side inlet, and the width of the lower side outlet of the material guide shell 10 is less than the width of the upper side inlet; an adjusting component is arranged on the connecting shell 9, and is used to change the angle of the material guide shell 10.

[0023] In the above scheme, a conveying device can be arranged under the frame 1 for conveying the block mold 5. The telescopic end of the first electric push rod 4 is initially in a retracted state. At least two second electric push rods 6 are arranged and are respectively located on both sides of the mounting shell 3 to improve the stability of the mounting frame 7. The telescopic end of the second electric push rod 6 is initially in an extended state. The feed pipe between the discharge port of the lower hopper 2 and the connecting shell 9 is a hose. A blocking valve is arranged at the discharge port of the lower hopper 2 for controlling the discharge of the block raw materials in the lower hopper 2. The outlet of the guide shell 10 allows the block raw materials entering the block mold 5 from the guide shell 10 to directly fill the corners of the block mold 5, thereby reducing bubbles generated in the corners of the block mold 5 due to flow and reducing the thickness of the block raw materials entering the block mold 5, thereby making the bubbles between the block raw materials gradually entering the block mold 5 easier to rupture.

[0024] See also Figure 2 and Figure 4-Figure 7 The adjustment component includes: a connecting block 11, fixed to the connecting shell 9, the connecting block 11 is slidably connected to a sliding rod 12, and the sliding rod 12 is fixed to a rack 13; a gear 14, fixed to the guide shell 10, the gear 14 is meshed with the rack 13; two symmetrically distributed blocking blocks 15, respectively fixed to the two sides of the mounting frame 7, and the two blocking blocks 15 are both located on the moving path of the sliding rod 12.

[0025] In the above solution, the rack 13 is used to drive the gear 14 to rotate so as to adjust the angle of the material guiding shell 10 .

[0026] See also Figure 6 and Figure 7The adjustment component also includes: two symmetrically distributed transmission rods 16, both of which are slidably connected to the sliding rod 12, and a first elastic member is fixedly connected between the transmission rod 16 and the sliding rod 12; a limit block 17, which is slidably connected to the sliding rod 12, and a second elastic member is fixedly connected between the two, the transmission rod 16 is used to limit the limit block 17, two limit grooves are provided on the connecting block 11, and the limit groove of the connecting block 11 is used to limit the limit block 17, and the blocking block 15 and the adjacent transmission rod 16 squeeze each other.

[0027] In the above scheme, a slope is provided on the side of the transfer rod 16 close to the limit block 17, and symmetrically distributed slopes are provided on the limit block 17. The transfer rod 16 drives the limit block 17 to move by squeezing the adjacent slopes on the limit block 17. The first elastic member between the transfer rod 16 and the sliding rod 12 is set as a spring, which is used to drive the transfer rod 16 to reset. The second elastic member between the limit block 17 and the sliding rod 12 is set as a spring, which is used to drive the limit block 17 to reset. The blocking block 15 squeezes the transfer rod 16 to move the transfer rod 16.

[0028] See also Figure 4 , Figure 5 and Figure 8 , also includes: a sliding frame 18, which is limitedly slidably connected to the mounting shell 3, the sliding frame 18 is slidably connected to a sliding frame 19, the mounting frame 7 passes through the sliding frame 19, and a plurality of vibrating rods 20 are installed on the lower side of the sliding frame 19; a connecting plate 21, which is fixedly connected to the connecting shell 9, and the connecting plate 21 is limitedly slidably connected to the sliding frame 19; a plurality of limiting plates 22, which are all fixedly connected to the sliding frame 19, the limiting plates 22 are located above the mounting frame 7, and the mounting frame 7 is located on the moving path of the limiting plates 22; a smoothing component, which is arranged in the mounting shell 3 and is used to smooth the surface of the block.

[0029] In the above scheme, the vibrating rod 20 is an existing electric vibrating rod, and all the vibrating rods 20 are evenly distributed on both sides of the material guide shell 10. The connecting plate 21 is used to drive the sliding frame 19 to move left and right. When the mounting frame 7 contacts the limiting plate 22, it is used to provide support for the sliding frame 19.

[0030] When using the device to produce concrete composite blocks (hereinafter referred to as concrete blocks), the staff transports the block mold 5 to the bottom of the mounting shell 3 through the conveying device, and then the staff controls the telescopic end of the first electric push rod 4 to extend, and the telescopic end of the first electric push rod 4 drives the mounting shell 3 and the parts thereon to move downward until the lower side of the mounting shell 3 contacts the upper side of the block mold 5 and stops, and then the staff starts the vibrating rod 20 and the electric rotating rod 8, and opens the blocking valve in the lower hopper 2, so that the block raw materials in the lower hopper 2 enter the block mold 5 through the feed pipe of the lower hopper 2, the connecting shell 9, the connecting pipe of the connecting shell 9 and the material guide shell 10.

[0031] In the process of the block raw materials in the lower hopper 2 entering the block mold 5, the electric rotating rod 8 drives the connecting shell 9 to move back and forth left and right, and in the process of the connecting shell 9 moving to the right, the connecting shell 9 drives the parts thereon to move back and forth left and right. When the connecting shell 9 moves to the right side of the mounting frame 7, the transfer rod 16 on the right side is squeezed by the blocking block 15 on the right side, so that the transfer rod 16 on the right side moves to the left and compresses the first elastic member thereon. The transfer rod 16 moves to the left and the inclined surface thereon squeezes the inclined surface on the right side of the limit block 17. The limit block 17 moves downward and compresses the second elastic member thereon, so that the limit block 17 and the limit groove on the right side of the connecting block 11 are released from the limit. At this time, the transfer rod 16 on the right side completely enters the sliding rod 12, and the right side surface of the sliding rod 12 contacts the blocking block 15 on the right side.

[0032] After the limit block 17 and the limit groove on the right side of the connecting block 11 are released from the limit, the elastic force of the first elastic part of the right transfer rod 16 is released. At this time, the right transfer rod 16 is blocked by the right blocking block 15, so that the sliding rod 12 moves to the left, and the sliding rod 12 drives the rack 13 to move to the left, and the rack 13 drives the gear 14 to rotate counterclockwise, and the gear 14 drives the guide shell 10 to swing to the right, until the sliding rod 12 drives the limit block 17 to align with the limit groove on the left side of the connecting block 11, the elastic force of the second elastic part of the limit block 17 is released and drives the limit block 17 to move upward, so that the limit block 17 is limited by the limit groove on the left side of the connecting block 11, thereby locking the position of the rack 13, thereby locking the angle of the guide shell 10 through the gear 14, and tilting the guide shell 10 to the right.

[0033] After the limit block 17 is limited by the limit groove on the left side of the connecting block 11, the connecting shell 9 moves to the rightmost side of the reciprocating thread of the electric rotating rod 8, and then the electric rotating rod 8 drives the connecting shell 9 to move to the left, and the transmission rod 16 on the right side is out of contact with the blocking block 15 on the right side, and the connecting shell 9 moves to the left. When the transmission rod 16 on the left side contacts the blocking block 15 on the left side, the transmission rod 16 on the left side moves to the right and compresses the first elastic member thereon, and the transmission rod 16 on the left side squeezes the limit block 17 downward, and the limit block 1 7 and the limiting groove on the left side of the connecting block 11 are released, the elastic force of the first elastic member of the left transfer rod 16 is released and drives the sliding rod 12 to move to the right, and finally the rack 13 drives the material guide shell 10 to swing to the left through the gear 14. After the limiting block 17 is aligned with the limiting groove on the right side of the connecting block 11, the limiting block 17 moves upward under the elastic force of the second elastic member thereon and is limited by the limiting groove on the right side of the connecting block 11, and at the same time the angle of the material guide shell 10 is locked, and at this time the material guide shell 10 tilts to the left.

[0034] When the connecting shell 9 moves back and forth left and right, when the connecting shell 9 moves from one side of the mounting frame 7 to the other side, a part of the telescopic end of the second electric push rod 6 is recovered, driving the mounting frame 7 and the parts thereon to move upward. After that, the above-mentioned action is repeated, so that when the connecting shell 9 moves to the right, the guide shell 10 tilts to the left, and when the connecting shell 9 moves to the left, the guide shell 10 tilts to the right, so that the block material entering the block mold 5 from the guide shell 10 first fills the corners of the block mold 5, reducing the bubbles generated in the corners of the block mold 5, and the block material entering the block mold 5 is filled in a layer-by-layer manner, and when filling, the guide shell 10 enters the interior of the block mold 5 and gradually rises, reducing the impact force of the block material entering the interior of the block mold 5, reducing the bubbles formed inside the block material due to the impact, and improving the integrity of the concrete block.

[0035] In the process of the connecting shell 9 moving back and forth to fill the block raw materials into the block mold 5, the connecting shell 9 drives the connecting plate 21 to move synchronously, the connecting plate 21 drives the sliding frame 19 to move back and forth, and the sliding frame 19 drives all the vibrating rods 20 to move back and forth, and the high-frequency vibration of the vibrating rods 20 is transmitted to the block raw materials entering the block mold 5, so that the bubbles in the block raw materials can escape, thereby improving the compactness of the block raw materials in the block mold 5 and ensuring the overall strength of the concrete block.

[0036] When the second electric push rod 6 drives the mounting frame 7 to move upward, the mounting frame 7 drives the connecting shell 9 to move upward through the electric rotating rod 8, and the connecting shell 9 drives the connecting plate 21 to move upward, so that the connecting plate 21 and the sliding frame 19 slide relative to each other. Subsequently, after the mounting frame 7 moves to contact with the limit plate 22, the mounting frame 7 drives the sliding frame 19 to move upward through the limit plate 22, and the sliding frame 19 drives the sliding frame 18 and the vibrating rod 20 to move upward. Subsequently, when the second electric push rod 6 drives the mounting frame 7 to move upward, the mounting frame 7 synchronously drives the sliding frame 19 to move upward through the limit plate 22. By triggering the mounting frame 7 and the sliding frame 19 in sequence when the sliding frame 19 moves for the first time, when the subsequent vibrating rod 20 removes bubbles from the block raw materials entering the block mold 5, a part of the vibrating rod 20 is always located in the block raw materials that have been debubbled and compacted. While the vibrating rod 20 removes bubbles from the block raw materials newly entering the block mold 5, the tightness between the layers of block raw materials is improved, thereby improving the overall strength of the concrete block.

[0037] After completing the filling of the block raw materials in the block mold 5, the staff closes the sealing valve and the electric rotating rod 8 in the lower hopper 2, and controls the telescopic end of the first electric push rod 4 to retract, so that the mounting shell 3 drives the parts inside it to move upward, and then controls the telescopic end of the second electric push rod 6 to extend and reset, so that the mounting frame 7 moves downward to the initial position. While the mounting frame 7 moves downward, the sliding frame 18 moves downward synchronously with the mounting frame 7, and stops after the sliding frame 18 moves to the limit of the mounting shell 3. At this time, the sliding frame 18 and the parts on the mounting frame 7 are all moved to the initial horizontal height. Then the staff replaces the block mold 5 that is already filled with block raw materials through the conveying device and repeats the above actions to produce concrete blocks.

[0038] Example 2: Based on Example 1, please refer to Figure 4 , Figure 5 , Fig. 9 and Fig.10 , also includes a smoothing component, which is arranged in the installation shell 3 and is used to smooth the surface of the block raw material. The smoothing component includes: four sliding sleeves 23, which are slidably connected to the two sides of the inside of the installation shell 3 in groups of two, a third elastic member is fixedly connected between two adjacent sliding sleeves 23 in different groups of the installation shell 3, and two sliding sleeves 23 in the same group of the installation shell 3 are slidably connected to a connecting frame 24 together, a fourth elastic member is fixedly connected between the sliding sleeve 23 and the adjacent connecting frame 24, a smoothing plate 25 is rotatably connected to the lower side of the connecting frame 24, and a fifth elastic member is fixedly connected between the two, and the two smoothing plates 25 are fixedly connected to the sides away from each other with elastic plates, and the two smoothing plates 25 are squeezed against each other on the sides close to each other.

[0039] In the above scheme, the third elastic member of the sliding sleeve 23 is set as a spring, the fourth elastic member between the sliding sleeve 23 and the connecting frame 24 is set as a spring, and the fifth elastic member between the connecting frame 24 and the trowel plate 25 is set as a tension spring. The trowel plate 25 is initially inclined toward the center point of the mounting shell 3, and the length of the trowel plate 25 is consistent with the width of the inner side of the block mold 5. After the trowel plate 25 enters the block mold 5, the front and rear sides of the trowel plate 25 contact the front and rear sides of the block mold 5, and the elastic plate of the trowel plate 25 and the front and rear sides of the trowel plate 25 contact the front and rear sides of the block mold 5, so that when the trowel plate 25 smoothes the block raw materials in the block mold 5, the block raw materials in the block mold 5 are prevented from entering the top of the trowel plate 25. When the elastic plate of the trowel plate 25 contacts the side wall of the block mold 5, the elastic plate of the trowel plate 25 is deformed to ensure the smoothing effect of the trowel plate 25 on the block raw materials near the side wall of the block mold 5.

[0040] See also Fig. 9 and Fig.10The smoothing assembly also includes: two extrusion rods 26, which are respectively limitedly slidably connected to adjacent connecting frames 24, and the extrusion rods 26 are used to push adjacent trowel plates 25 to rotate; two first hydraulic telescopic rods 27, which are respectively fixed to two sliding sleeves 23 in different groups, and the telescopic ends of the first hydraulic telescopic rods 27 are fixed to the adjacent extrusion rods 26. The mounting shell 3 is fixed with two second hydraulic telescopic rods 28, and a return spring is arranged in the second hydraulic telescopic rods 28. The telescopic ends of the two second hydraulic telescopic rods 28 are both located on the moving path of the sliding frame 18, and an oil pipeline is connected between the second hydraulic telescopic rod 28 and the adjacent first hydraulic telescopic rods 27.

[0041] In the above scheme, the first hydraulic telescopic rod 27, the second hydraulic telescopic rod 28 and the oil pipe therebetween are all filled with hydraulic oil. When the telescopic end of the second hydraulic telescopic rod 28 is squeezed by the sliding frame 18, the oil pipe thereon transmits hydraulic oil to drive the telescopic end of the first hydraulic telescopic rod 27 to extend, so that the squeezing rod 26 pushes the trowel plate 25 to rotate to a horizontal state, so as to smooth the block raw materials in the block mold 5.

[0042] See also Figure 4 and Figure 8-Figure 10 The smoothing assembly also includes: two C-shaped rods 29, which are respectively fixed to two sliding sleeves 23 of different groups. The sliding frame 19 is fixed to two elastic telescopic plates 30. The telescopic parts of the elastic telescopic plates 30 are used to limit the adjacent C-shaped rods 29. The C-shaped rod 29 is provided with an inclined surface, and the inclined surface of the C-shaped rod 29 is used to squeeze the telescopic parts of the adjacent elastic telescopic plates 30.

[0043] In the above solution, after the telescopic portion of the elastic telescopic plate 30 is located inside the C-shaped rod 29 , the movement of the elastic telescopic plate 30 can drive the C-shaped rod 29 to move, thereby causing the C-shaped rod 29 to drive the sliding sleeve 23 to move.

[0044] After completing the filling of the block raw materials in the block mold 5, the staff closes the blocking valve in the lower hopper 2, and controls the electric rotating rod 8 to move the connecting shell 9 to the middle of the electric rotating rod 8, and then controls the telescopic end of the second electric push rod 6 to continue to retract until the telescopic end of the second electric push rod 6 drives the sliding frame 18 to move to the upper side of the mounting shell 3 through the mounting frame 7, the limit plate 22 and the sliding frame 19, so that the sliding frame 18 squeezes the telescopic end of the second hydraulic telescopic rod 28, and the telescopic end of the second hydraulic telescopic rod 28 contracts (at this time, the telescopic end of the second hydraulic telescopic rod 28 is not completely contracted), and the inner spring is compressed, and the hydraulic oil in the second hydraulic telescopic rod 28 enters the first hydraulic telescopic rod 27 through its adjacent oil pipe, and the telescopic end of the first hydraulic telescopic rod 27 extends.

[0045] When the telescopic end of the first hydraulic telescopic rod 27 is extended, the telescopic end of the first hydraulic telescopic rod 27 drives the extrusion rod 26 to move downward, and the extrusion rod 26 pushes the trowel plate 25 to swing into the block mold 5. At the same time, the fifth elastic member of the trowel plate 25 is stretched until the extrusion rod 26 moves to the limit position between it and the connecting frame 24. At this time, the trowel plate 25 swings to a state parallel to the horizontal plane. Then the staff starts the electric rotating rod 8, and the electric rotating rod 8 drives the connecting shell 9 to move back and forth left and right. The connecting shell 9 drives the sliding frame 19 to move back and forth left and right through the connecting plate 21. The movable frame 19 drives the elastic telescopic plate 30 to move back and forth left and right. During the reciprocating movement of the two elastic telescopic plates 30, after the elastic telescopic plate 30 moves to contact the adjacent C-shaped rods 29 (taking one of them as an example), the inclined surface of the C-shaped rod 29 squeezes the telescopic portion of the elastic telescopic plate 30, and the telescopic portion of the elastic telescopic plate 30 contracts. When the telescopic portion of the elastic telescopic plate 30 enters the interior of the C-shaped rod 29, the telescopic portion of the elastic telescopic plate 30 extends out and limits the C-shaped rod 29, and then the elastic telescopic plate 30 can drive the sliding sleeve 23 to move through the C-shaped rod 29.

[0046] After the telescopic portion of one of the elastic telescopic plates 30 is limited by the adjacent C-shaped rod 29, the sliding frame 19 drives the elastic telescopic plate 30 to move in the opposite direction, and drives the sliding sleeve 23 to move synchronously through the C-shaped rod 29. The sliding sleeve 23 compresses the third elastic member thereon, and the movement of the sliding sleeve 23 drives the connecting frame 24 to move, and the trowel plate 25 moves synchronously with the connecting frame 24 until the telescopic portion of the other elastic telescopic plate 30 contacts the adjacent C-shaped rod 29 and limits the C-shaped rod 29. At this time, the opposite sides of the two trowel plates 25 contact each other, and the third elastic member of the sliding sleeve 23 is compressed to the limit. Then, the telescopic end of the second electric push rod 6 is controlled to be completely retracted, and finally the sliding frame 18 pushes the second hydraulic telescopic rod 28 The telescopic end of the connecting shell 9 is fully retracted, and its inner spring is fully compressed. At this time, the telescopic end of the first hydraulic telescopic rod 27 is fully extended, and the connecting frame 24 is pushed downward by the extrusion rod 26. The fourth elastic member of the connecting frame 24 is compressed, and the connecting frame 24 moves downward to drive the trowel plate 25 to move downward, so that the trowel plate 25 gradually fits with the upper surface of the block raw material filled in the block mold 5. Subsequently, during the reciprocating movement of the connecting shell 9, the two trowel plates 25 move synchronously to smooth the upper surface of the block raw material in the block mold 5. During this process, the two trowel plates 25 are located on the lower side of the material guide shell 10 to prevent the material guide shell 10 from dripping the block raw material to damage the flatness of the surface of the block raw material in the block mold 5.

[0047] During the process of the trowel plate 25 smoothing the upper surface of the block material in the block mold 5, when the trowel plate 25 moves to contact the side wall of the block mold 5 on the same side, the elastic plate of the trowel plate 25 is squeezed and deformed by the side wall of the block mold 5, so that the trowel plate 25 smoothes the block material close to the side wall of the block mold 5. After smoothing the block material in the block mold 5, the telescopic end of the first electric push rod 4 is reset, driving the mounting shell 3 and the parts thereon to move upward, the mounting shell 3 is out of contact with the block mold 5, and then the block mold 5 can be removed.

[0048] After the telescopic end of the first electric push rod 4 is reset, the staff controls the electric rotating rod 8 to move the connecting shell 9 to the middle of the electric rotating rod 8, and then controls the telescopic end of the second electric push rod 6 to extend and reset, and the mounting frame 7 and the sliding frame 18 move downward and reset, and respectively drive the parts thereon to move downward. In this process, the sliding frame 18 releases the squeezing of the telescopic end of the second hydraulic telescopic rod 28, and the telescopic end of the elastic telescopic plate 30 releases the limit on the C-shaped rod 29. The third elastic parts of the two adjacent sliding sleeves 23 move away from each other and reset under the action of their own elastic force, and the second hydraulic The telescopic end of the telescopic rod 28 is reset under the elastic action of the spring thereon, and the telescopic end of the first hydraulic telescopic rod 27 is driven to reset through the oil pipeline thereon and the hydraulic oil in the first hydraulic telescopic rod 27. The telescopic end of the first hydraulic telescopic rod 27 drives the extrusion rod 26 to reset. The thrust applied by the extrusion rod 26 to the connecting frame 24 and the trowel plate 25 disappears. The connecting frame 24 is reset under the elastic force of the fourth elastic member thereon, and the trowel plate 25 is reset under the tensile force of the fifth elastic member thereon. The above-mentioned actions are repeated when the surface of the block raw material in the block mold 5 needs to be smoothed later.

[0049] Example 3: Based on Example 2, please refer to Figure 1-Figure 5 , also includes: a sealing gasket 31, which is arranged on the block mold 5; an extrusion ring 32, which is fixed to the mounting shell 3, and the lower side of the extrusion ring 32 is provided with an arc surface. The extrusion ring 32 is used to squeeze the sealing gasket 31, and the mounting shell 3 is fixed and connected with an exhaust pipe 33.

[0050] In the above scheme, when the extrusion ring 32 squeezes the sealing gasket 31, the sealing gasket 31 is deformed, so that a closed chamber is formed in the installation shell 3 and the block mold 5. When the arc surface on the lower side of the extrusion ring 32 squeezes the sealing gasket 31, the sealing gasket 31 gradually contacts and deforms with the extrusion ring 32 from the middle to both sides, avoiding the existence of air between the extrusion ring 32 and the sealing gasket 31, thereby improving the sealing effect between the extrusion ring 32 and the sealing gasket 31, and the exhaust pipe 33 is connected to an external exhaust device.

[0051] When the installation shell 3 moves downward and contacts the block mold 5, the extrusion ring 32 squeezes the sealing gasket 31 to deform the sealing gasket 31. At this time, a closed chamber is formed in the installation shell 3 and the block mold 5. Subsequently, during the process of filling the block raw materials, the installation shell 3 and the block mold 5 are continuously evacuated through the exhaust pipe 33, so that a negative pressure is generated between the installation shell 3 and the block mold 5, thereby accelerating the escape of bubbles in the block raw materials filled in the block mold 5, improving the tightness between the block raw materials, and improving the overall strength of the concrete block. After completing the filling of the block raw materials in the block mold 5, the exhaust can be stopped, and the above-mentioned action is repeated when the block raw materials in the block mold 5 are deaerated.

[0052] It should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
