[0026] Reference Figure 1 The automatic demolding mechanism for bending according to this utility model includes a lower mold base 100, a demolding mechanism 200, and a driving mechanism 300. The lower mold base 100 is provided with a bending groove 120 for bending and shaping. A sliding groove 110 is provided inside the lower mold base 100. The sliding groove 110 is located below the bending groove 120, and the upper end of the sliding groove 110 passes through the bottom of the bending groove 120. The demolding mechanism 200 is slidably built into the sliding groove 110 and moves up and down in the sliding groove 110. The driving mechanism 300 is built into the sliding groove 110 and is fixedly connected to the demolding mechanism 200, and is used to drive the demolding mechanism 200 to move up and down.

[0027] In practical use, the upper mold base (not shown in the figure) cooperates with the lower mold base 100 to place the wear-resistant tile plate in the bending groove 120 for bending and shaping. After bending, the drive mechanism 300 provides power to make the demolding mechanism 200 reciprocate linearly in the slide groove 110 and drive the demolding mechanism 200 to slide upward along the slide groove 110 to push the bent wear-resistant tile plate out of the bending groove 120. After the push is completed, when the upper mold base descends and bends the wear-resistant tile plate again, the demolding mechanism 200 is passively slid downward to reset and cooperates with the bending groove 120 to bend the next wear-resistant tile plate.

[0028] In summary, after the wear-resistant tile is fully bent in the bending groove 120, the driven mechanism 300 automatically pushes out the bent wear-resistant tile, saving time and improving production efficiency.

[0029] In some embodiments, refer to Figure 1 The slide 110 is provided with an upper limit block 111 and a lower limit block 112, and the demolding mechanism 200 is provided with an abutment block 210. The abutment block 210 can abut against the upper limit block 111 or the lower limit block 112 to constrain the movement path of the demolding mechanism 200. When the demolding mechanism 200 slides upward, the abutment block 210 abuts against the upper limit block 111, restricting the demolding mechanism 200 from moving further upward and determining the upper limit position of the demolding mechanism 200; when the demolding mechanism 200 slides downward, the abutment block 210 abuts against the lower limit block 112, restricting the demolding mechanism 200 from moving further downward and determining the lower limit position of the demolding mechanism 200, ensuring that the demolding mechanism 200 moves within the set path. The mechanical limiting structure (the limiting block and the abutment block 210 cooperate) precisely limits the movement range of the demolding mechanism 200, avoiding damage to the equipment or failure to demold due to excessive movement, and ensuring the stability and accuracy of the demolding action.

[0030] In some embodiments, refer to Figure 1 The lower mold base 100 has a groove 130 on its bottom surface, located below the slide groove 110. The lower limit block 112 is plate-shaped and is embedded in the groove 130, and fixedly connected to the lower mold base 100. When installing the lower limit block 112, the plate-shaped lower limit block 112 is embedded into the groove 130 on the bottom surface of the lower mold base 100, and then fixed to the lower mold base 100 by a fixing method (such as welding), so that the lower limit block 112 is stably located below the slide groove 110, providing support and limiting for the lower limit position of the demolding mechanism 200. Using the groove 130 to position and initially fix the lower limit block 112 facilitates installation. Furthermore, after the lower limit block 112 is firmly installed, it can withstand the impact force when the demolding mechanism 200 moves downward, ensuring the reliability of the limiting function, and also facilitating the installation, disassembly, and maintenance of the lower limit block 112.

[0031] Preferably, refer to Figure 1 The lower limit block 112 and the lower mold base 100 are fixedly connected by screws. The screw connection method is simple and reliable, facilitates the disassembly and replacement of the lower limit block 112, and ensures the connection strength to meet the force requirements of the demolding mechanism 200 when it is in the limit position.

[0032] In some embodiments, the driving mechanism 300 is a spring, one end of which is fixedly connected to the lower limit block 112, and the other end is fixedly connected to the demolding mechanism 200. In actual processing, when the wear-resistant tile is bent in the bending groove 120, the demolding mechanism 200 moves downward under the pressure of the wear-resistant tile and the upper mold, compressing the spring to store elastic potential energy; after bending is completed, the external force is removed, the spring releases its elastic potential energy, and pushes the demolding mechanism 200 upward to push out the bent wear-resistant tile; when the demolding mechanism 200 reaches the upper limit, the spring is in an extended state. When bending again, the external force (the force from the downward pressure of the upper mold seat) pushes the demolding mechanism 200 downward to compress the spring, repeating the cycle and performing repeated bending processing.

[0033] It is worth mentioning that, referring to Figure 1 The demolding mechanism 200 is provided with a guide groove 220, and the driving mechanism 300 is embedded in the guide groove 220. The upper end of the driving mechanism 300 is fixedly connected to the upper end of the guide groove 220. A spring is embedded in the guide groove 220 of the demolding mechanism 200. The upper end of the spring is fixed to the upper end of the guide groove 220, and the lower end is connected to the lower limit block 112 or other fixed components. When the demolding mechanism 200 moves up and down, the spring extends and retracts axially in the guide groove 220. The guide groove 220 constrains the direction of movement of the spring to prevent the spring from bending or deviating when under force. It should be mentioned that the lower limit block 112 is provided with a guide post 140, the drive mechanism 300 is sleeved on the guide post 140, the guide post 140 is fixed on the lower limit block 112, and the spring is sleeved on the outside of the guide post 140. When the demolding mechanism 200 is raised and lowered, the spring extends and retracts along the axial direction of the guide post 140. The guide post 140 provides support and guidance for the spring, restricts the radial displacement of the spring, and makes it only move along the direction of the guide post 140.

[0034] In the above embodiments, it is ensured that the spring always applies force along the movement direction of the demolding mechanism 200, avoiding jamming or uneven force on the demolding mechanism 200 due to spring deflection, improving the stability and reliability of the drive mechanism 300, reducing the radial sway of the spring during operation, improving the service life of the spring, and ensuring that the demolding mechanism 200 rises and falls stably in the vertical direction, avoiding tilting or jamming.

[0035] To further constrain the travel path of the demolding mechanism 200, refer to Figure 2The demolding mechanism 200 has limiting grooves 230 on both sides, and a slider 150 is correspondingly provided on the inner side of the slide groove 110. The slider 150 and the limiting grooves 230 are slidably connected. The limiting grooves 230 on both sides of the demolding mechanism 200 cooperate with the slider 150 in the slide groove 110. When the demolding mechanism 200 rises and falls, the limiting grooves 230 slide along the slider 150. The slider 150 guides and limits the limiting grooves 230, restricting the lateral movement of the demolding mechanism 200 so that it can only move in the vertical direction of the slide groove 110. This ensures that the demolding mechanism 200 remains stable during the rising and falling process, avoids lateral deviation or shaking, improves the movement accuracy and reliability of the demolding mechanism 200, and reduces equipment failures caused by movement deviations.

[0036] In some embodiments, refer to Figure 3 The upper surface of the demolding mechanism 200 is an arc surface. When the abutting block 210 and the lower limit block 112 abut, the upper surface of the demolding mechanism 200 and the bending groove 120 smoothly transition, so that the bending groove 120 is a smooth curved surface. When the demolding mechanism 200 is in the lower limit position (the abutting block 210 abuts with the lower limit block 112), the upper surface of its arc surface fits against the bottom of the bending groove 120, forming a continuous smooth curved surface. During bending, the wear-resistant tile is bent and shaped in the bending groove 120 of the smooth curved surface. After bending is completed, the demolding mechanism 200 rises, the arc surface disengages from the bending groove 120, and the workpiece is pushed out. The smooth curved surface reduces the friction between the wear-resistant tile and the mold during bending, avoids scratches on the workpiece surface, and facilitates the smooth forming and demolding of the workpiece in the bending groove 120.

[0037] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
