Description

Technical Field

[0001] This utility model relates to the field of demolding device technology, specifically an automatic demolding device based on PC board steel mold. Background Technology

[0002] PC board steel molds are steel molds used for the factory precasting of concrete slabs. With their high strength, high flatness and reusability, they ensure accurate dimensions and stable surface quality of the PC boards after molding, making them the core tooling for the production of PC components in prefabricated buildings. Demolding refers to the process of separating and removing the hardened PC board from the inner wall of the steel mold after it has been cast and cured to the specified strength. The automatic demolding device for PC board steel molds is the key system for automating this process.

[0003] Existing devices mostly use rigid impact or single vibration to achieve demolding. Rigid impact can easily cause steel mold deformation or PC board edge and corner damage, surface scratches and other defects, and it is also inconvenient to stack the demolded steel mold.

[0004] Based on this, an automatic demolding device based on PC board steel mold is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0005] The purpose of this invention is to provide an automatic demolding device based on PC board steel molds, so as to solve the problem that the prior art often uses rigid impact or single vibration to achieve demolding, which easily leads to damage to the steel mold and concrete.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An automatic demolding device based on PC board steel mold includes a base, a conveyor belt on the top of the base, four support rods fixedly installed on the top of the base, and a top plate between the tops of the four support rods. The bottom of the top plate is provided with an installation groove, the inside of the installation groove is provided with a drive mechanism, the outside of the drive mechanism is provided with a movable frame, the inside of the movable frame is fixedly installed with a first hydraulic cylinder, the output end of the first hydraulic cylinder passes through the movable frame and is connected to a lifting frame, and the inside of the lifting frame is provided with a vibration mechanism.

[0007] Based on the above technical solutions, this utility model also provides the following optional technical solutions: In one alternative: the driving mechanism includes a lead screw, which is rotatably mounted inside the mounting slot via a bearing; a first motor is fixedly mounted on one side of the top plate; the lead screw is driven by the first motor; and the moving frame is threadedly connected to the lead screw.

[0008] In one alternative: the vibration mechanism includes a second motor, which is fixedly installed inside the lifting frame. The output end of the second motor is keyed to a cam. A connecting rod is rotatably mounted on one side of the cam via a pin. A telescopic sleeve is rotatably mounted on one end of the connecting rod via a pin, and the telescopic sleeve is slidably mounted to the lifting frame.

[0009] In one alternative: a telescopic rod is slidably installed inside the telescopic sleeve, a lower pressure plate is provided at the bottom end of the telescopic rod, a soft pad is provided at the bottom of the lower pressure plate, and a spring is provided inside the telescopic sleeve and above the telescopic rod.

[0010] In one alternative: the bottom of the lifting frame is provided with two clamping mechanisms.

[0011] In one alternative: the clamping mechanism includes a fixed plate, which is fixedly installed at the bottom of the lifting frame. A second hydraulic cylinder is fixedly installed on one side of the fixed plate. The output end of the second hydraulic cylinder passes through the fixed plate and is connected to a clamping plate. An anti-slip pad is provided on one side of the clamping plate.

[0012] In one alternative: a limiting rod is fixedly installed on the other side of the clamping plate, and the limiting rod and the fixed plate are slidably installed.

[0013] In one alternative: a placement rack is provided on top of the base and on one side of the conveyor belt.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The vibration mechanism of this utility model achieves high-frequency flexible impact vibration on the steel mold through the combination of cam, connecting rod, telescopic sleeve and spring (soft pad buffer avoids hard impact damage), so that the concrete and steel mold are evenly separated. With the help of the clamping mechanism, the force is stabilized, which solves the problem of PC board edge and corner damage and surface defects that are easily caused by manual demolding, and the yield rate is increased to more than 98%.

[0015] 2. This utility model integrates conveying, demolding, transfer and stacking functions. After the steel mold is demolded, it is directly transferred to the placement rack for stacking by the drive mechanism, avoiding the site occupation and collision damage caused by random placement of steel molds, making the precast component production site cleaner and more orderly, and improving the utilization rate of workshop space.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] In one embodiment, such as Figures 1-4 As shown, the automatic demolding device based on PC board steel mold includes a base 1, a conveyor belt 2 is provided on the top of the base 1, four support rods 3 are fixedly installed on the top of the base 1, and a top plate 4 is provided between the tops of the four support rods 3. The bottom of the top plate 4 is provided with an installation groove 5. The installation groove 5 is provided with a drive mechanism 6. The drive mechanism 6 is provided with a movable frame 7. The movable frame 7 is fixedly installed with a first hydraulic cylinder 8. The output end of the first hydraulic cylinder 8 passes through the movable frame 7 and is connected to a lifting frame 9. The lifting frame 9 is provided with a vibration mechanism 10. The top of the base 1 and one side of the conveyor belt 2 is provided with a placement frame 12.

[0023] In this embodiment, the steel mold is placed on the conveyor belt 2 with its opening facing downwards. The conveyor belt 2 transports the steel mold to directly below the lifting frame 9. The first hydraulic cylinder 8 drives the lifting frame 9 to move downwards, so that the two clamping mechanisms 11 are located on both sides of the steel mold. The two clamping mechanisms 11 clamp the steel mold. At this time, the vibration mechanism 10 works to knock and vibrate the steel mold, causing the concrete to separate from the steel mold. The first hydraulic cylinder 8 slowly retracts, causing the steel mold to move upwards. The conveyor belt 2 continues to transport the demolded concrete. The drive mechanism 6 works to drive the moving frame 7 to move, thereby moving the steel mold above the placement frame 12. Finally, the steel mold is stacked on the placement frame 12.

[0024] In one embodiment, such as Figure 1 and Figure 2As shown, the drive mechanism 6 includes a lead screw 61, which is rotatably mounted inside the mounting groove 5 via a bearing. A first motor 62 is fixedly mounted on one side of the top plate 4. The lead screw 61 is driven by the first motor 62. The movable frame 7 is threadedly connected to the lead screw 61. The first motor 62 drives the lead screw 61 to rotate, and the rotation of the lead screw 61 drives the movable frame 7 to move, thereby changing the position of the lifting frame 9 as needed.

[0025] In one embodiment, such as Figure 3 and Figure 4 As shown, the vibration mechanism 10 includes a second motor 101, which is fixedly installed inside the lifting frame 9. A cam 102 is keyed to the output end of the second motor 101. A connecting rod 103 is rotatably mounted on one side of the cam 102 via a pin. A telescopic sleeve 104 is rotatably mounted on one end of the connecting rod 103 via a pin, and the telescopic sleeve 104 is slidably mounted to the lifting frame 9. A telescopic rod 105 is slidably mounted inside the telescopic sleeve 104. A lower pressure plate 107 is provided at the bottom end of the telescopic rod 105, and a soft pad 108 is provided at the bottom of the lower pressure plate 107. The telescopic sleeve 104 is located inside the telescopic... A spring 106 is installed above the rod 105. When the steel mold is clamped, the second motor 101 drives the cam 102 to rotate. When the cam 102 rotates and drives the connecting rod 103 to move to the top, the connecting rod 103 drives the telescopic sleeve 104 to move upward, and the soft pad 108 separates from the steel mold. As the cam 102 drives the connecting rod 103 to move downward, the telescopic sleeve 104 slides downward, causing the soft pad 108 to strike the top of the steel mold. The telescopic sleeve 104 continues to slide downward, and the telescopic rod 105 slides into the interior of the telescopic sleeve 104. The spring 106 is compressed, and the second motor 101 continues to rotate, causing the steel mold to vibrate, thereby separating the concrete from the steel mold.

[0026] In one embodiment, such as Figure 3 and Figure 4As shown, the bottom of the lifting frame 9 is provided with two clamping mechanisms 11. Each clamping mechanism 11 includes a fixed plate 111, which is fixedly installed at the bottom of the lifting frame 9. A second hydraulic cylinder 112 is fixedly installed on one side of the fixed plate 111. The output end of the second hydraulic cylinder 112 passes through the fixed plate 111 and is connected to a clamping plate 113. An anti-slip pad 114 is provided on one side of the clamping plate 113, and a limit rod 115 is fixedly installed on the other side of the clamping plate 113. The limit rod 115 and the fixed plate 111 are slidably installed. When the two clamping mechanisms 11 are located on both sides of the steel mold, the two second hydraulic cylinders 112 work to drive the clamping plate 113 to move, so that the two anti-slip pads 114 contact the steel mold, thereby clamping and fixing the steel mold. After the steel mold moves to the top of the placement rack 12, the two second hydraulic cylinders 112 retract, the clamping of the steel mold is released, and the steel mold is stacked on the top of the placement rack 12 for easy retrieval during subsequent use.

[0027] The above embodiments disclose an automatic demolding device based on a PC board steel mold. The steel mold is placed on a conveyor belt 2 with its opening facing downwards. The conveyor belt 2 transports the steel mold to directly below a lifting frame 9. A first hydraulic cylinder 8 moves the lifting frame 9 downwards, positioning two clamping mechanisms 11 on either side of the steel mold. Two second hydraulic cylinders 112 move clamping plates 113, causing two anti-slip pads 114 to contact the steel mold, thus clamping and fixing it. A second motor 101 rotates a cam 102. When the cam... When the wheel 102 rotates and drives the connecting rod 103 to move to the top, the connecting rod 103 drives the telescopic sleeve 104 to move upward, and the soft pad 108 separates from the steel mold. As the cam 102 drives the connecting rod 103 to move downward, the telescopic sleeve 104 slides downward, causing the soft pad 108 to strike the top of the steel mold. The telescopic sleeve 104 continues to slide downward, and the telescopic rod 105 slides into the interior of the telescopic sleeve 104. The spring 106 is compressed, and the second motor 101 continues to rotate, causing the steel mold to vibrate, thereby separating the concrete from the steel mold.

[0028] The first hydraulic cylinder 8 slowly retracts, causing the steel mold to move upward. The conveyor belt 2 continues to transport the demolded concrete. The first motor 62 drives the lead screw 61 to rotate, and the rotation of the lead screw 61 drives the moving frame 7 to move, thereby moving the steel mold above the placement frame 12. Finally, the steel mold is stacked on the placement frame 12 for easy retrieval during subsequent use.
