[0001] This utility model belongs to the field of mold technology, specifically relating to a mold for making aerated concrete blocks. Background Technology

[0002] Utility model patent CN217891312U discloses a mold for manufacturing porous autoclaved aerated concrete (AAC) blocks, including a lower concave mold and an upper convex mold. The lower concave mold has an open top and a rectangular shell-like structure. The upper convex mold includes a cover plate and four cylinders. The cover plate is fastened to the upper port of the lower concave mold. The cover plate has four rectangular arrayed threaded holes. A thickened annular protrusion is integrally formed on the outer periphery of each threaded hole on the upper surface of the cover plate. The inner circle of the thickened annular protrusion has an internal thread that connects with the threaded hole. The cylinders are arranged vertically, and the outer circle of the upper end of the cylinder has an external thread. The upper part of each cylinder extends into and is threaded into the inner circle of the thickened annular protrusion and the threaded hole of the cover plate. There is a gap between the lower end face of the four cylinders and the bottom surface of the lower concave mold. This utility model has a simple structure and is easy to operate. While ensuring strength, it sets several heat-insulating and weight-reducing holes distributed in a rectangular array in the block, which can reduce raw material consumption, reduce the self-weight of the block, and has good heat insulation performance, improved seismic performance, and further reduce production costs. However, when using this device, it is inconvenient to separate the blocks from the mold after they are formed. Also, air bubbles may exist inside the blocks after they are formed, which affects the strength of the blocks. Summary of the Invention

[0003] The purpose of this utility model is to provide a mold for making aerated concrete blocks, which solves the problem that it is inconvenient to separate the blocks from the mold after they are formed when using existing molds for making aerated concrete blocks. In addition, air bubbles will exist inside the blocks after they are formed, which will affect the strength of the blocks.

[0004] To achieve the above objectives, this utility model provides a mold for making aerated concrete blocks, including a base plate. Two molds are slidably connected to the upper end of the base plate, and the two molds are in contact. A sliding plate is welded to the edge of each mold, and the sliding plate is slidably connected to the base plate. A dovetail block is welded to the lower end of the sliding plate. A fixing mechanism is provided on each mold. An upper mold is slidably connected to the outer side of the upper end of the mold. A pressure plate is welded to the lower end of the upper mold, and the pressure plate is slidably connected to the mold. A limiting mechanism is provided on the base plate. The fixing mechanism includes a screw cylinder, a bidirectional screw rod, a knob, a locking block, and a locking groove. Two symmetrical screw cylinders are threadedly connected to the outer side of the bidirectional screw rod. A knob, made of plastic, is fixedly connected to the outer side of the middle part of the bidirectional screw rod. One of the screw cylinders is hinged to one of the molds, and a locking block is fixedly connected to the end of the other screw cylinder. By sliding the mold on the base plate, the two molds can be easily engaged and disengaged. The rotation of the bidirectional screw and the screw barrel creates a threaded motion, facilitating the engagement and disengagement of the locking block and the locking groove. This allows for easy assembly and disassembly of the two molds, making it easy to detach the formed block. The limiting mechanism includes a screw, a retaining ring, a connecting block, a spring, and a screw ring. The screw is fixedly connected to the upper end of the base plate, located at the front end of the mold. A retaining ring is fixedly sleeved on the outer side of the screw. A connecting block is movably connected to the outer side of the screw, and the connecting block is fixedly connected to the upper mold. A spring is provided on the outer side of the screw. By sliding the pressure plate and the mold, and by rotating the screw ring and the screw creating a threaded motion, the pressure plate is pressed tightly within the mold, compressing the block material and reducing air bubbles, resulting in a denser and stronger block after molding.

[0005] The principle of this invention is as follows: When making blocks, the mold is manually slidable, allowing it to slide on the base plate. Then, the screw cylinder is rotated, causing the locking block to insert into the slot. Next, the double-headed screw is rotated, creating a threaded motion between the screw and the screw cylinder, bringing the two screw cylinders closer together. This causes the locking block to tighten the two molds. Concrete is then poured between the two molds. The sliding of the mold on the base plate facilitates the separation and engagement of the two molds, and the threaded motion of the double-headed screw and screw cylinder further facilitates the separation and engagement of the locking block and the slot, thus enabling easy assembly and disassembly of the two molds. This process facilitates the release of the formed blocks. The upper mold is then manually rotated, causing the connecting block to rotate outside the screw. The upper mold rotates above the two molds. The screw ring and screw are then manually rotated to create a threaded motion, causing the screw ring to move downwards. This presses down the connecting block, pressing the upper mold against the outside of the molds. The pressure plate slides between the two molds, compressing the block material. Through the sliding of the pressure plate and molds, and the threaded motion of the screw ring and screw, the pressure plate is pressed tightly within the molds, compressing the block material and reducing air bubbles. This results in a denser, stronger block after molding.

[0006] The beneficial effects of this utility model are as follows: by sliding the mold on the base plate, it is easy to separate and engage between the two molds, and by rotating the bidirectional screw and the screw cylinder to make threaded movement, it is easy to separate and engage between the locking block and the locking groove, and thus it is easy to separate and assemble the two molds, making it easy to detach the block after it is formed.

[0007] By sliding the pressure plate and the die, and by rotating the screw ring and screw to make a threaded motion, the pressure plate is pressed into the die, which squeezes the block material, reduces air bubbles in the material, and makes the block more compact and stronger after molding.

[0008] Furthermore, a dovetail groove is provided at the upper end of the base plate, and the dovetail groove and the dovetail block are slidably connected. By setting the dovetail groove and the dovetail block in cooperation, the movement of the slide plate is guided.

[0009] Furthermore, a slot is provided on the side of another mold, and the slot and the locking block are slidably connected. By setting the slot and the locking block to cooperate, the molds are positioned relative to each other.

[0010] Furthermore, one end of the spring contacts the connecting block, and the other end of the spring contacts the retaining ring. The spring design facilitates the repositioning of the connecting block.

[0011] Furthermore, a threaded ring is connected to the outer side of the screw, and the threaded ring contacts the connecting block. The threaded ring limits the position of the connecting block. Attached Figure Description

[0016] The reference numerals in the accompanying drawings include: base plate 1, mold 2, slide plate 3, fixing mechanism 4, upper mold 5, pressure plate 6, limiting mechanism 7, screw barrel 41, bidirectional screw 42, knob 43, locking block 44, locking groove 45, screw 71, retaining ring 72, connecting block 73, spring 74, and screw ring 75.

[0017] like Figure 1As shown, this embodiment provides a mold for making aerated concrete blocks, including a base plate 1. Two molds 2 are slidably connected to the upper end of the base plate 1. The two molds 2 are in contact. A sliding plate 3 is welded to the edge of the mold 2. The sliding plate 3 is slidably connected to the base plate 1. A dovetail block is welded to the lower end of the sliding plate 3. A dovetail groove is provided at the upper end of the base plate 1. The dovetail groove and the dovetail block are slidably connected. By setting the dovetail groove and the dovetail block to cooperate, the movement of the sliding plate 3 is guided. A fixing mechanism 4 is provided on the mold 2. An upper mold 5 is slidably connected to the outer side of the upper end of the mold 2. A pressure plate 6 is welded to the lower end of the upper mold 5. The pressure plate 6 is slidably connected to the mold 2. A limit mechanism 7 is provided on the base plate 1.

[0018] like Figure 1 , Figure 2 As shown, the fixing mechanism 4 includes a screw barrel 41, a bidirectional screw rod 42, a knob 43, a locking block 44, and a locking groove 45. Two symmetrical screw barrels 41 are threadedly connected to the outer side of the bidirectional screw rod 42. A knob 43, made of plastic, is fixedly connected to the outer side of the middle part of the bidirectional screw rod 42. One screw barrel 41 is hinged to one of the molds 2. A locking block 44 is fixedly connected to the end of the other screw barrel 41. A locking groove 45 is opened on the side of the other mold 2. The locking groove 45 and the locking block 44 are slidably connected. By setting the locking groove 45 and the locking block 44 to cooperate, the molds 2 are limited. By sliding the molds 2 on the base plate 1, the two molds 2 can be easily separated and engaged. By rotating the bidirectional screw rod 42 and the screw barrel 41 to make threaded movement, the locking block 44 and the locking groove 45 can be easily separated and engaged, thus making it easy to separate the two molds 2 after they are formed.

[0019] like Figure 1 , Figure 3 As shown, the limiting mechanism 7 includes a screw 71, a retaining ring 72, a connecting block 73, a spring 74, and a screw ring 75. The screw 71 is fixedly connected to the upper end of the base plate 1 and the front end of the mold 2. The retaining ring 72 is fixedly sleeved on the outside of the screw 71. The connecting block 73 is movably connected to the outside of the screw 71. The connecting block 73 is fixedly connected to the upper mold 5. The spring 74 is provided on the outside of the screw 71. One end of the spring 74 contacts the connecting block 73, and the other end of the spring 74 contacts the retaining ring 72. By providing the spring 74, the connecting block 73 can be easily reset. The screw ring 75 is threadedly connected to the outside of the screw 71. The screw ring 75 contacts the connecting block 73. By providing the screw ring 75, the connecting block 73 is limited. The pressure plate 6 slides with the mold 2, and by rotating the screw ring 75 and the screw 71 to make threaded movement, the pressure plate 6 is pressed into the mold 2, which squeezes the block material, reduces air bubbles in the material, and makes the block more compact and stronger after molding.

[0020] The specific implementation process of this utility model is as follows: When making blocks, the mold 2 is manually slidable, allowing it to slide on the base plate 1. Then, the screw cylinder 41 is rotated, causing the locking block 44 to insert into the slot 45. Next, the double-acting screw 42 is rotated, creating a threaded motion between the screw cylinder 41 and the double-acting screw 42, bringing the two screw cylinders 41 closer together. This causes the locking block 44 to tighten the two molds 2. Concrete is then poured between the two molds 2. By sliding the mold 2 on the base plate 1, the two molds 2 can easily separate and engage. Furthermore, by rotating the double-acting screw 42 and the screw cylinder 41 to create a threaded motion, the locking block 44 and the slot 45 can easily separate and engage, thus facilitating the separation and engagement of the two molds 2. The assembly and disassembly process facilitates the separation of the formed blocks. Then, the upper mold 5 is manually rotated, causing the connecting block 73 to rotate outside the screw 71. This rotates the upper mold 5 above the two molds 2. The screw ring 75 and screw 71 are then manually rotated to create a threaded motion, causing the screw ring 75 to move downwards. This presses down the connecting block 73, pressing the upper mold 5 against the outside of the mold 2. The pressure plate 6 slides between the two molds 2, compressing the block material. Through the sliding of the pressure plate 6 and the mold 2, and by rotating the screw ring 75 and screw 71 to create a threaded motion, the pressure plate 6 is pressed tightly inside the mold 2, compressing the block material and reducing air bubbles. This results in a denser and stronger block after molding.

[0021] By sliding the mold 2 on the base plate 1, it is easy to separate and engage between the two molds 2. By rotating the bidirectional screw 42 and the screw barrel 41 to make threaded movement, it is easy to separate and engage between the locking block 44 and the locking groove 45, which makes it easy to separate and assemble the two molds 2, and makes it easy to detach the block after it is formed.

[0022] By sliding the pressure plate 6 and the mold 2, and by rotating the screw ring 75 and the screw 71 to make threaded movements, the pressure plate 6 is pressed into the mold 2, which squeezes the block material, reduces air bubbles in the material, and makes the block more compact and stronger after molding.
