Description

Technical Field

[0001] This utility model belongs to the technical field of mold equipment for bridge construction, and specifically relates to a hydraulic forming device for the side mold panel of a T-beam mold. Background Technology

[0002] In bridge construction, T-beams are commonly used load-bearing components, and their production quality directly affects the overall structural safety of the bridge. T-beams are usually formed by casting using molds, and the forming and demolding process of the side mold panels is a key step in T-beam production.

[0003] Problems with existing technology: Existing T-beam mold side panel forming devices often suffer from problems such as difficulty in demolding, low precision in adjusting the movement of the side panel, and poor structural stability during the forming process. Traditional demolding methods often rely on manual labor or a single power mechanism, which can easily lead to the side mold sticking to the formed T-beam, affecting not only the surface quality of the T-beam but also potentially damaging the mold. Utility Model Content

[0004] The purpose of this invention is to provide a hydraulic forming device for the side mold panel of a T-beam mold, which can apply a pushing force to the T-beam to complete the secondary demolding, effectively preventing the T-beam from sticking to the side mold panel. Furthermore, the stroke of the second hydraulic cylinder is controllable, and the moving distance can be adjusted according to the degree of adhesion to prevent damage to the T-beam and the mold.

[0005] The specific technical solution adopted by this utility model is as follows: A hydraulic forming device for the side mold panel of a T-beam mold includes a base, two mounting seats are provided on the top of the base, and a movable plate is slidably provided on the top of the mounting seats; Side templates are provided on the outer side of opposite sides of the two movable plates, and a demolding mechanism is provided between the side templates and the movable plates.

[0006] The demolding mechanism includes a second hydraulic cylinder installed on one side of the moving plate. The output shaft of the second hydraulic cylinder is fixed with a connecting seat that is connected to the side template, which is used to drive the side template to move within a small range.

[0007] The outer wall of the movable plate is fixed with mounting ears on both the upper and lower sides of the second hydraulic cylinder. A connecting rod is rotatably mounted on the other end of the mounting ears. Limit grooves are formed on both sides of the outer wall of the connecting rod at its connection point.

[0008] Multiple mounting slots are symmetrically opened on both sides of the outer wall of the side template. A movable block is inserted into the inside of the mounting slot. A top block is provided on the outside of the movable block. In the initial state, one side of the top block is flush with the outer wall of the side template.

[0009] Two second guide rods are fixed on one side of the top block, and a guide groove is provided on one side of the moving block to slide with the second guide rods. A spring is sleeved on the outer wall of the second guide rod.

[0010] Multiple first guide rods are fixed on one side of the side template, and one end of each first guide rod passes through the outer wall of the moving block and the moving plate in sequence.

[0011] Limiting rods that mate with limiting grooves are fixed on the inner side of the connecting seat and between the two transverse moving blocks.

[0012] A connecting plate is provided on one side of the two bottom movable blocks to connect with the upper movable block.

[0013] The top of the mounting base is provided with a first hydraulic cylinder that is connected to the movable plate.

[0014] A bottom mold is fixed at the top of the base and between the mounting seats, and the top of the bottom mold is flush with the top of the mounting seats.

[0015] The technical effects achieved by this utility model are as follows: This invention uses a first hydraulic cylinder to drive a movable plate to slide along the mounting base, which can quickly adjust the spacing between the two side templates to meet the forming requirements of T-beams of different sizes. At the same time, the threaded tie rod can fix the movable plate after adjustment, effectively enhancing the overall structural stability of the device and preventing shaking during casting and demolding.

[0016] The demolding mechanism enables secondary demolding. The second hydraulic cylinder drives the side template to move within a small range to complete the initial demolding. Simultaneously, the connecting rod and limit rod drive the moving block and top block to protrude from the side template surface, applying a pushing force to the T-beam to complete the secondary demolding. This effectively prevents the T-beam from sticking to the side template. Furthermore, the stroke of the second hydraulic cylinder is controllable, allowing adjustment of the movement distance according to the degree of adhesion to prevent damage to the T-beam and mold. The top block is initially flush with the side template, not affecting the T-beam forming quality, and its smooth surface reduces damage to the T-beam surface. The spring can quickly reset the top block after demolding, improving the reusability of the device. Attached Figure Description

[0019] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0020] like Figures 1-3 As shown, a hydraulic forming device for the side mold panel of a T-beam mold includes a base 1, two mounting seats 3 are provided on the top of the base 1, a movable plate 4 is slidably provided on the top of the mounting seat 3, a first hydraulic cylinder 5 connected to the movable plate 4 is provided on the top of the mounting seat 3, and a threaded tie rod 17 is provided between the two movable plates 4. The threaded tie rod 17 can effectively enhance the overall structural stability of the device.

[0021] Side templates 12 are provided on the outside of the opposite side of the two movable plates 4, and a demolding mechanism is provided between the side templates 12 and the movable plates 4.

[0022] like Figures 1-5 As shown, the demolding mechanism includes a second hydraulic cylinder 6 installed on one side of the moving plate 4. The output shaft of the second hydraulic cylinder 6 is fixed with a connecting seat 7 connected to the side template 12, which is used to drive the side template 12 to move within a small range. The moving plate 4 serves as the mounting base for the side template 12 and the demolding mechanism. It can drive the side template 12 to move within a large range under the drive of the first hydraulic cylinder, thus meeting the side mold spacing adjustment requirements for forming T-beams of different sizes. The outer wall of the movable plate 4 and the upper and lower sides of the second hydraulic cylinder 6 are fixed with mounting ears 8. The other end of the mounting ears 8 is rotatably mounted with a connecting rod 9. Limit grooves 10 are opened on both sides of the outer wall of the connecting rod 9 at its connection point. Multiple mounting slots are symmetrically opened on both sides of the outer wall of the side template 12. A movable block 13 is inserted into the inside of the mounting slot. A top block 15 is provided on the outside of the movable block 13. In the initial state, one side of the top block 15 is flush with the outer wall of the side template 12. A limiting rod 16 that cooperates with the limiting slot 10 is fixed on the inner side of the connecting seat 7 and between the two transverse movable blocks 13. Two second guide rods 14 are fixed on one side of the top block 15, and a guide groove is provided on one side of the moving block 13 to slide with the second guide rods 14. A spring is sleeved on the outer wall of the second guide rods 14.

[0023] According to the above structure, the second hydraulic cylinder 6 has a controllable stroke and can adjust its movement distance according to the degree of adhesion between the T-beam and the side template 12, avoiding excessive demolding force that could damage the T-beam or the mold. The connecting rod 9, as a transmission component of the demolding mechanism, can convert the movement of the connecting seat 7 into the driving power of the moving block 13, realizing the linkage of the demolding action. The limiting groove 10 cooperates with the limiting rod 16 to limit the rotation angle of the connecting rod 9, ensuring transmission accuracy and avoiding excessive rotation that could damage the mechanism. The top block 15 does not affect the forming quality of the T-beam in its initial state. During demolding, it can protrude from the surface of the side template 12 under the drive of the moving block 13, applying a pushing force to the T-beam and assisting the side template 12 to complete the demolding, avoiding adhesion between the T-beam and the side template 12. Its smooth surface can reduce damage to the surface of the T-beam.

[0024] like Figures 1-3 As shown, a plurality of first guide rods 11 are fixed on one side of the side template 12, and one end of the first guide rod 11 passes through the outer wall of the moving block 13 and the moving plate 4 in sequence.

[0025] A connecting plate is provided on one side of the two bottom movable blocks 13 to connect with the upper movable block 13.

[0026] like Figure 1 As shown, a bottom mold 2 is fixed on the top of the base 1 and between the mounting bases 3. The top of the bottom mold 2 is flush with the top of the mounting base 3. This design ensures that the side template 12 and the bottom mold 2 are precisely connected, avoiding grout leakage or dimensional deviation during the casting of the T-beam due to the height difference.

[0027] The working principle of this utility model is as follows: In use, firstly, according to the T-beam size requirements, the first hydraulic cylinder 5 is activated. The first hydraulic cylinder 5 drives the moving plate 4 to slide along the top of the mounting base 3, moving the side template 12 to a preset position. The moving plate 4 is then fixed by the threaded tie rod 17. Subsequently, concrete is poured into the forming cavity formed by the bottom mold 2 and the two side templates 12. After the concrete solidifies, the second hydraulic cylinder 6 is activated. The second hydraulic cylinder 6 drives the connecting seat 7 to move the side template 12 a small distance away from the T-beam, achieving initial demolding. Simultaneously... The limiting rod 16 on the inner side of the connecting seat 7 slides along the limiting groove 10 of the connecting rod 9, causing the connecting rod 9 to rotate around the mounting ear 8. The connecting rod 9 cooperates with the limiting rod 16 between the limiting groove 10 at the other end and the moving block 13, driving the moving block 13 to move along the mounting groove and the first guide rod 11, thereby causing the top block 15 to protrude from the surface of the side template 12, applying a pushing force to the T beam to achieve secondary demolding. After demolding is completed, the second hydraulic cylinder 6 resets, and the spring drives the top block 15 to reset along the second guide rod 14. The connecting rod 9 and the moving block 13 are then reset, waiting for the next molding operation.

[0028] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
