Description

Technical Field

[0001] This invention relates to the field of precast block molding mold technology, specifically to an energy-saving concrete precast block molding device. Background Technology

[0002] Among energy-saving precast concrete blocks, foamed concrete precast blocks are widely used in construction due to their good thermal insulation and lightweight properties. However, because the foaming and expansion process of foamed concrete slurry is unstable, direct single-block casting can easily lead to uneven foaming, mold collapse, and large dispersion in pore size and density among individual blocks. Casting large blanks first can ensure that the pore size, density, and strength of the entire blank are uniform and consistent. Then, cutting can flexibly obtain blocks of various specifications with higher dimensional accuracy and fewer edge defects. Current energy-saving precast concrete block forming molds are difficult to cut directly without demolding. Foamed concrete itself is lightweight, and after the blank is cast, the side molds need to be completely removed. The blank is transported by supporting the bottom mold for subsequent cutting operations. The stability of the blank transport by supporting the bottom mold alone is not good, and the blank is prone to slippage, making it difficult to achieve the positioning and protection of the blank. Moreover, during the cutting process, the blank is also prone to shaking and rubbing on the bottom mold under the friction of the cutting wire.

[0003] Therefore, we propose an energy-saving precast concrete block forming device. Summary of the Invention

The four rows of side mold pieces are rotatably mounted on four mold-closing shafts. The four rows of side mold pieces are rotatably fitted around the bottom mold. There is a gap between adjacent side mold pieces in each row. The side mold pieces at both ends of each row have inclined surfaces for closing into a rectangle.

[0016] This invention employs a mold assembly system with four rows of side mold pieces, facilitating rapid mold assembly and reducing the cost of replacing individual side mold pieces during subsequent demolding. The four rows of side mold pieces can be independently connected to the bottom mold, and the spacing between adjacent side mold pieces in each row eliminates the need for demolding after the blank has solidified. The gaps between the side mold pieces allow the wire cutting machine to pass through without affecting normal cutting. Furthermore, during wire cutting, the four rows of side mold pieces provide limiting protection on the outer periphery of the blank, preventing displacement due to friction during wire cutting, which could affect cutting quality, cause chipping, and exceed accuracy tolerances.

[0017] The upper mold is designed for easy disassembly after the billet is formed. Irregular protruding areas on the top of the billet can be cut off without demolding; only the upper mold needs to be removed. The slit joint piece facilitates the connection of the side mold pieces and maintains the installation stability of the upper mold. At the same time, the slit plate can be inserted into the gap between the two side mold pieces, which is the slit for subsequent cutting of the billet. This ensures that the foamed concrete can be properly formed and cured in the early stage. When cutting is required, the slit plate can be removed separately without affecting the cutting operation, while ensuring the forming quality of the foamed concrete. Attached Figure Description

[0030] Example 1: Please refer to Figures 1 to 10 As shown:

[0031] This invention provides a technical solution: an energy-saving precast concrete block forming device, including a forming installation component 1, on which a mold assembly component 2 is installed, the mold assembly component 2 being used to form precast concrete block blanks; a cutting slit is reserved on the mold assembly component 2; a connecting upper mold component 3 is installed on the mold assembly component 2; a row of cutting slit connecting components 4 are respectively provided around the upper mold component 3; the four rows of cutting slit connecting components 4 are used to connect the upper mold component 2; the forming installation component 1 includes: a bottom mold 101 and a drain outlet 1011, the bottom of the bottom mold 101 has a cavity structure, and drain outlets 1011 are respectively opened around the bottom mold 101; the drain outlets 1011 are connected to the cavity at the bottom of the bottom mold 101.

[0032] The molding installation component 1 further includes: fork slots 1012 and mold closing shafts 102. Two fork slots 1012 are provided at the bottom of the bottom mold 101. Four mold closing shafts 102 are fixedly inserted into the bottom mold 101. A drain outlet 1011 is located above the mold closing shafts 102. The molding installation component 1 also includes: a base plate 103, reinforcing ribs 104, water channels 1041, and a water inlet pipe 105. The base plate 103 is fixedly installed at the bottom of the bottom mold 101. Two reinforcing ribs 104 are fixedly installed inside the bottom cavity of the bottom mold 101. The bottom of the two reinforcing ribs 104 is fixedly attached to the base plate 103. A row of water channels 1041 is provided at the bottom of the reinforcing ribs 104, and the water channels 1041 are used to connect the four water channels 105. A water inlet pipe 105 is fixedly installed on the bottom mold 101, and the water inlet pipe 105 is connected to an external water source. The water inlet pipe 105 connects to the internal cavity of the bottom mold 101. The molding installation part 1 is used, which facilitates flexible transportation by forklift and is more suitable for workshop rotation for subsequent blank cutting. At the same time, this structure is equipped with four drain outlets 1011, which facilitates the workers to brush and clean the bottom mold 101 and the side mold pieces 201 without the need for manual water hose rinsing, making it more flexible to use. The drain outlets 1011 are located at the hinge of the side mold pieces 201, which facilitates the rinsing and cleaning of impurities at the mating surfaces of the side mold pieces 201 and the bottom mold 101.

[0033] The mold assembly 2 includes: side mold pieces 201, diagonal connecting holes 2011, and through slots 2012. The side mold pieces 201 are arranged in four rows, forming a rectangular molding cavity. The four rows of side mold pieces 201 are rotatably mounted on four mold-closing shafts 102. The four rows of side mold pieces 201 rotatably fit around the bottom mold 101. There is a gap between adjacent side mold pieces 201 in each row. The side mold pieces 201 at both ends of each row have inclined surfaces for closing into a rectangle. Diagonal connecting holes 201 are respectively opened on the side mold pieces 201 at both ends of each row. The mold assembly 2 includes connecting holes 2011 and through slots 2012; two adjacent diagonal connecting holes 2011 are used to insert bolts; the mold assembly 2 also includes fixing bolts 202, with fixing bolts 202 inserted into each of the four rows of side mold pieces 201, and the fixing bolts 202 are threaded onto the bottom mold 101; the fixing bolts 202 are used to press the side mold pieces 201 to fit against the side of the bottom mold 101; the mold assembly 2 also includes guide cylinders 203 and positioning pins 204, with the through slots 2012 for the positioning pins 204 to pass through, and guide cylinders 203 are fixedly installed on each of the four rows of side mold pieces 201; there are four positioning pins 204, and the four positioning pins 204 are respectively... Do not insert it onto the four rows of side mold pieces 201; the tail end of the positioning pin 204 is bent, and the front end of the positioning pin 204 has a tapered structure; using the mold assembly 2, by setting four rows of side mold pieces 201, it is easy to quickly assemble the mold, and at the same time, the replacement cost of a single side mold piece 201 is lower when disassembling the mold later; the four rows of side mold pieces 201 can be independently connected to the bottom mold 101, and the side mold pieces 201 in each row have a gap between adjacent side mold pieces 201. After the blank is formed and cured, it is not necessary to demold before cutting. The gap between the side mold pieces 201 can allow the cutting wire of the wire cutting machine to pass through without affecting the process. During normal cutting and processing, the four rows of side molds 201 can limit and protect the outer periphery of the blank during the wire cutting process, avoiding blank displacement caused by friction during wire cutting, which would affect the cutting quality, cause chipping, and result in excessive precision deviation. The structure is more reasonable. Since the manufacturing process of foamed concrete blocks involves multiple steps, the bottom mold 101 also undertakes the transfer of the blank after it is formed. Before cutting, the foamed concrete blank is usually semi-dry. By limiting the blank on the outside, the bottom mold 101 supports the blank more stably when transferring it between workstations, avoiding blank slippage and making it more suitable for workstation transitions.

[0034] In Example 2, based on Example 1, the upper mold component 3 includes: an upper mold frame 301, a constricted rubber pad 3011, lifting rings 302, and handles 303. The upper mold frame 301 is located above the four rows of side mold pieces 201. The constricted rubber pad 3011 is fixedly sleeved on the inner side of the upper mold frame 301, and the inner side of the constricted rubber pad 3011 has a sloping structure. Four lifting rings 302 are fixedly installed on the upper mold frame 301. Four handles 303 are fixedly installed on the upper mold frame 301. The upper mold component 3 also includes: guide shafts 304, four rows of guide shafts 304 are fixedly installed at the bottom of the upper mold frame 301, and the four rows of guide shafts 304 are slidably sleeved on the four rows of guide cylinders 203 respectively; and four sets of cutting and joining parts. Includes: a slit insert plate 401 and an insertion hole 4011. The slit insert plate 401 is positioned at the interval between adjacent side mold pieces 201 in each row of side mold pieces 201. The slit insert plate 401 is rotatably mounted on the upper mold frame 301. The slit insert plate 401 is inserted into two adjacent side mold pieces 201 on the same side. The inner end face of the slit insert plate 401 is flush with the inner sides of the two adjacent side mold pieces 201. An insertion hole 4011 is provided on the slit insert plate 401. A positioning pin 204 on the same side passes through the insertion hole 4011. The slit connecting part 4 also includes: a baffle plate 402 and a positioning bolt 403. The baffle plate 402 is fixedly installed on the slit insert plate 401. The baffle plate 402 abuts against and fits against the mold frame 301. On the edges of the two side mold pieces 201 on the same side; positioning bolts 403 are inserted into the bottom of the baffle 402, and the positioning bolts 403 are threaded onto the side mold pieces 201 on the same side; the use of the upper mold piece 3 facilitates separate disassembly after the blank is formed, and the irregular protruding area on the top of the blank can be cut off. Similarly, demolding is not required, only the upper mold piece 3 needs to be removed. The operation is simple and flexible. The upper mold piece 3 can prevent the slurry from overflowing when it foams and expands. After the foamed concrete slurry is poured, the side wall of the mold cavity generates frictional constraint on the edge slurry, which inhibits the edge foaming and expansion. The slurry in the middle of the mold cavity is not subject to lateral constraint and can foam freely upward. The bubbles rise and gather, so that the blank after forming is The top surface forms an arched protrusion in the middle, which affects the uniformity of the block height. The protruding part needs to be cut off and removed. At the same time, this part of the material can be crushed and reused. The cutting joint piece 4 is used to facilitate the connection of the side mold piece 201 and maintain the installation stability of the upper mold piece 3. At the same time, the cutting joint plate 401 can be inserted into the gap between the two side mold pieces 201, which is the cutting joint of the subsequent cutting of the blank. This can ensure the normal molding and curing of the foamed concrete in the early stage. When cutting is required, the cutting joint plate 401 can be removed separately without affecting the normal cutting operation, while ensuring the molding quality of the foamed concrete and preventing grout leakage. The installation and removal of the cutting joint plate 401 is also simple and flexible.

[0035] The working principle of this embodiment is as follows: First, the mold closing operation: the four rows of side mold pieces 201 are brought together inward, and then the fixing bolts 202 on each side mold piece 201 are tightened and fixed on the bottom mold 101 by wrench. Then, bolts are inserted into the diagonal connecting holes 2011 at the four corners and tightened by nuts. Then, the guide shaft 304 at the bottom of the upper mold frame 301 is inserted into the corresponding guide cylinder 203 for docking. Then, each slit plate 401 is rotated and inserted into the gap between two adjacent side mold pieces 201 to seal the gap. Then, the positioning bolts 403 on each baffle 402 are threaded onto the side mold piece 201 to tighten the slit plate 401. Then, the positioning pin 204 is inserted into a row of side mold pieces 201 on the same side and passes through a row of insertion holes 4011 on the same side to further position the middle of the slit plate 401.

[0036] Pouring operation: Pour the foamed concrete slurry into the four rows of side formwork plates 201 in a measured amount. Wait for the foamed concrete to expand. At this time, the level of foamed concrete will gradually exceed the bottom edge of the upper formwork frame 301, and the surface will bulge. After the foamed concrete has solidified, first rotate and remove the positioning bolts 403, and pull the cutting plate 401 out from between the side formwork plates 201. Then, the upper formwork frame 301 can be lifted upwards by manually holding the handle 303, or the cable can be passed through the lifting ring 302. The upper mold frame 301 is connected to a crane for easy lifting and disassembly. The rubber pad 3011 on the inner side of the upper mold frame 301 has a sloping structure for easy demolding. After the upper mold frame 301 is disassembled, the bottom mold 101 is transferred to the cutting station by inserting the fork of a fork into the fork slot 1012. The protruding area of ​​the blank above the top edge of the side mold piece 201 can be cut first. After removing the cutting insert plate 401, the gap between adjacent side mold pieces 201 can be used for cutting wire to pass through. During the cutting process, the side mold piece 201 is still firmly installed on the bottom mold 101 by the fixing bolts 202 to maintain the stability of the blank. The blank can then be transferred again for subsequent curing and other work. When it is necessary to remove the cut concrete blocks, loosen the fixing bolts 202, rotate the side mold piece 201 outward to separate it from the concrete block, and then the concrete block can be taken out.

[0037] After the concrete blocks are removed from the cut surface, when cleaning and washing the formwork is required, the workers can connect the water inlet pipe 105 to the water source pipe, supply cleaning water, and introduce it into the bottom formwork 101, which will then be discharged from the four drain outlets 1011. The workers can use a brush to scrub the bottom formwork 101 and the side formwork pieces 201 to carry out the rinsing and cleaning work. After cleaning is completed, the formwork can be put back into use.
