Description

Technical Field

[0001] The utility model relates to the technical field of asphalt concrete precast block forming, and particularly relates to an asphalt concrete precast block forming device. Background Art

[0002] Asphalt concrete precast blocks are precast materials used in road and infrastructure construction, made of asphalt mixtures. They have high strength, durability and good anti-slip performance, and are widely used in various engineering projects such as roads, airport runways, sidewalks and parking lots. During the production of asphalt concrete precast blocks, a forming device is required to press the evenly mixed asphalt mixture into precast blocks with specified shapes and sizes.

[0003] When the existing asphalt concrete precast block forming device is in use, first, the asphalt mixture is conveyed from the hopper to the lower mold of the forming device. Then, pressure is applied through a hydraulic cylinder to press the upper mold downward to compact the asphalt mixture. After forming, the precast block is taken out of the mold to complete the production.

[0004] However, in actual production, due to the long-term operation of the upper mold, the mold will wear, and at this time, the upper mold needs to be replaced. The existing replacement method is to manually disassemble the bolts fixing the upper mold with tools, and then repeat the above operation when installing a new mold. This process is relatively cumbersome and time-consuming, reducing the working efficiency of the forming device. Summary of the Utility Model

[0005] In order to make up for the above deficiencies, the utility model provides an asphalt concrete precast block forming device, aiming to improve the problem that in the prior art, the bolts fixing the upper mold are manually disassembled with tools, and then the above operation is repeated when installing a new mold, which is relatively cumbersome and time-consuming.

[0006] To achieve the above object, the utility model provides the following technical solutions:

[0007] An asphalt concrete precast block forming device includes a bracket. An installation plate is fixedly connected to the upper part of the bracket. A hydraulic cylinder is fixedly connected inside the installation plate. The output end of the hydraulic cylinder is fixedly connected to a fixed plate. An installation block is fixedly connected to the lower part of the fixed plate. An upper mold is inserted into the installation block. An installation pipe is fixedly connected to the right side inside the installation block. A moving block is slidably connected inside the installation pipe. A plug rod is fixedly connected to the left side of the outside of the moving block. A grip is fixedly connected to the front side of the outside of the moving block.

A spring is sleeved outside the second telescopic rod. A support plate is fixedly connected to the rear side outside the bracket. A blanking assembly is arranged below the support plate. The blanking assembly is used for the operation of blanking the pressed asphalt concrete precast blocks.

[0008] Further, the blanking assembly includes a motor. The motor is arranged below the support plate. The output end of the motor is fixedly connected to a turntable. A fixed rod is fixedly connected to the upper right side of the turntable. A guide rod is sleeved outside the fixed rod. The top of the guide rod is fixedly connected to a push plate.

[0009] Further, first telescopic rods are fixedly connected to both sides inside the installation plate. The tops of the two first telescopic rods are fixedly connected to both sides of the upper part of the fixed plate.

[0010] Further, a jack is opened inside the upper mold. The plug rod is inserted into the jack.

[0011] Further, a second through hole is opened on the left side inside the installation pipe. The plug rod is slidably connected inside the second through hole.

[0015] The utility model has the following beneficial effects:

[0016] 1. In the present utility model, when replacing the upper mold, first move the grip, which drives the moving block and the insertion rod to move, causing the second telescopic rod and the spring to contract synchronously. When the insertion rod disengages from the insertion hole, the upper mold can be removed. When installing a new mold, insert it into the mounting block, release the grip, and use the reaction force of the spring to insert the insertion rod into the insertion hole. This operation is convenient, solves the problem of manually disassembling bolts in the traditional method, and significantly improves the working efficiency of the molding equipment.

[0017] 2. In the present utility model, when discharging materials, separate the lower mold through two electric push rods, and then start the motor to drive the turntable to rotate. The turntable drives the fixed rod to rotate, which further pushes the guide rod to move. The guide rod drives the push plate to move on the bracket, and pushes the formed asphalt concrete precast block out from below the upper mold. This reduces the frequency of operators placing their hands below the upper mold and reduces the risk of injury. Description of the Drawings

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] Referring to Figure 1 、 Figure 4 and Figure 5 , an embodiment provided by the present utility model: a bituminous concrete precast block forming device, including a bracket 1, an upper part of the bracket 1 is fixedly connected with a mounting plate 2, a hydraulic cylinder 6 is fixedly connected inside the mounting plate 2, an output end of the hydraulic cylinder 6 is fixedly connected with a fixing plate 8, a lower part of the fixing plate 8 is fixedly connected with a mounting block 9, an upper die 18 is inserted inside the mounting block 9, a mounting pipe 10 is fixedly connected to the right side inside the mounting block 9, a moving block 12 is slidably connected inside the mounting pipe 10, a plug rod 16 is fixedly connected to the left side outside the moving block 12, a handle 15 is fixedly connected to the front side outside the moving block 12, a second telescopic rod 13 is fixedly connected to the right side inside the mounting pipe 10, a top of the second telescopic rod 13 is fixedly connected to the outside of the moving block 12, a spring 14 is sleeved outside the second telescopic rod 13, a support plate 22 is fixedly connected to the rear side outside the bracket 1, a blanking assembly 21 is arranged below the support plate 22, and the blanking assembly 21 is used for the operation of blanking the bituminous concrete precast blocks formed by pressing. First telescopic rods 7 are fixedly connected to both sides inside the mounting plate 2, tops of the two first telescopic rods 7 are fixedly connected to both upper sides of the fixing plate 8, a jack 17 is formed inside the upper die 18, the plug rod 16 is inserted into the jack 17, a second through hole 19 is formed in the left side inside the mounting pipe 10, the plug rod 16 is slidably connected inside the second through hole 19, a first through hole 11 is formed inside the mounting pipe 10, and the handle 15 is slidably connected inside the first through hole 11. Cross plates 3 are fixedly connected to both upper sides of the bracket 1, electric push rods 4 are fixedly connected inside the two cross plates 3, output ends of the two electric push rods 4 are fixedly connected with a lower die 5, and the two lower dies 5 are inserted into each other.

[0027] When it is necessary to replace the upper mold 18, first of all, the operator needs to move the grip 15. The movement of the grip 15 will drive the externally fixed moving block 12 to move together. As the moving block 12 moves, the insertion rod 16 fixed on the left side externally will also move accordingly. The movement of the insertion rod 16 will exert a force on the externally fixed second telescopic rod 13, causing it to contract. At the same time as the second telescopic rod 13 contracts, the externally sleeved spring 14 will also contract synchronously. When the insertion rod 16 completely disengages from the inside of the jack 17, the operator can take out the upper mold 18 from the inside of the mounting block 9 for replacement. When installing a new upper mold 18, the operator inserts the new upper mold 18 into the inside of the mounting block 9. Then, release the grip 15. Under the reaction force of the spring 14, the insertion rod 16 will be pushed back into the inside of the jack 17, thus fixing the new upper mold 18. In this way, the convenient replacement of the upper mold 18 is realized, avoiding the complex process of manually disassembling the bolts for fixing the upper mold 18 with tools in the traditional replacement method and then repeating the above operations when installing a new mold, improving the working efficiency of the molding equipment. When pressing asphalt concrete precast blocks, first, the two lower molds 5 are combined by the two electric push rods 4. Then, the asphalt concrete is placed inside the lower mold 5. Then, the hydraulic cylinder 6 is started. The hydraulic cylinder 6 drives the fixed plate 8 fixed to the output end to move. The movement of the fixed plate 8 drives the mounting block 9 fixed to the lower part to move. The movement of the mounting block 9 drives the upper mold 18 inserted inside to move. By making the upper mold 18 coincide with the lower mold 5, the operation of pressing and forming the asphalt concrete precast block can be completed.

[0028] Referring to Figure 2 and Figure 3 , the blanking assembly 21 includes a motor 2101. The motor 2101 is arranged at the lower part of the support plate 22. The output end of the motor 2101 is fixedly connected with a turntable 2102. The upper right side of the turntable 2102 is fixedly connected with a fixed rod 2103. The outside of the fixed rod 2103 is sleeved with a guide rod 2104. The top of the guide rod 2104 is fixedly connected with a push plate 2105. The lower part of the support plate 22 is fixedly connected with a U-shaped frame 20. The motor 2101 is fixedly connected inside the U-shaped frame 20.

[0029] During the blanking process, two electric push rods 4 are used to separate the two lower molds 5. Next, by starting the motor 2101, the motor 2101 drives the rotating disc 2102 fixed to its output end to rotate. The rotation of the rotating disc 2102 drives the fixed rod 2103 fixed to the outside on the right side to rotate synchronously. While the fixed rod 2103 rotates, it also drives the guide rod 2104 sleeved on the outside to move. The movement of the guide rod 2104 further drives the push plate 2105 fixed to the top to move on the upper part of the bracket 1. Through the movement of the push plate 2105, the formed asphalt concrete precast block is pushed out from below the upper mold 18, facilitating the pushing out of the formed asphalt concrete precast block from below the upper mold 18 during blanking, reducing the frequency of the operator placing their hand below the upper mold 18, and reducing the risk of the operator being injured. The U-shaped frame 20 is provided to facilitate the fixation of the motor 2101.

[0030] Working principle: When the upper mold 18 needs to be replaced, first, move the grip 15. The movement of the grip 15 drives the moving block 12 fixed to the outside to move. The movement of the moving block 12 drives the insertion rod 16 fixed to the outside on the left side to move. When the moving block 12 moves and drives the insertion rod 16 to move, it contracts the second telescopic rod 13 fixed to the outside. When the second telescopic rod 13 contracts, it drives the spring 14 sleeved on the outside to contract synchronously. When the insertion rod 16 disengages from the inside of the jack 17, the upper mold 18 can be taken out from the inside of the mounting block 9 for replacement. During installation, insert the new upper mold 18 into the inside of the mounting block 9, and then release the grip 15. Under the reaction force of the spring 14, insert the insertion rod 16 into the inside of the jack 17. This facilitates the replacement of the upper mold 18, solving the problem that the traditional replacement method is to manually disassemble the bolts fixing the upper mold 18 using tools and then repeat the above operations when installing a new mold. This operation method is simple, convenient, time-saving, and labor-saving, improving the working efficiency of the forming equipment. Then, during blanking, the two lower molds 5 are separated by two electric push rods 4. Then, by starting the motor 2101, the motor 2101 drives the rotating disc 2102 fixed to its output end to rotate. The rotation of the rotating disc 2102 drives the fixed rod 2103 fixed to the outside on the right side to rotate. The rotation of the fixed rod 2103 drives the guide rod 2104 sleeved on the outside to move. The movement of the guide rod 2104 drives the push plate 2105 fixed to the top to move on the upper part of the bracket 1. The formed asphalt concrete precast block can be pushed out from below the upper mold 18 through the movement of the push plate 2105, facilitating the pushing out of the formed asphalt concrete precast block from below the upper mold 18 during blanking, reducing the frequency of the operator placing their hand below the upper mold 18, and reducing the risk of the operator being injured.
