Description

Technical Field

[0001] The invention relates to the technical field of mold repair, and in particular to a multi-angle rotating mold repairing table. Background Art

[0002] In modern industrial production, molds are key equipment for product molding, and their precision and service life directly affect product quality and production efficiency.

[0003] Currently, most common mold repair tables on the market are fixed structures, with the mold typically fixed on the table in a single position. Operators must maneuver around the mold or frequently adjust their posture to inspect different parts. This operation method is not only inefficient but also easily causes operator fatigue, affecting mold repair accuracy. Working on the back or bottom of the mold is cumbersome and poses safety risks. Furthermore, because the mold's angle is fixed, inspecting and repairing complex internal structures often requires multiple disassembly and reassembly. This is not only time-consuming but can also lead to a decrease in mold accuracy due to repeated disassembly and assembly.

[0004] While some improved mold repair equipment features some angle adjustment capabilities, these adjustments are limited to horizontal rotation or vertical tilt, often failing to meet the needs of multi-angle, all-around repair. Furthermore, the mold clamping mechanisms of these devices are poorly designed. Either the clamping force is insufficient, allowing the mold to shift during the repair process, affecting machining accuracy; or the clamping method is too rigid, causing damage to the mold surface. This is especially true for high-precision, easily deformed molds, where traditional clamping methods struggle to maintain effective clamping while also protecting the mold surface quality.

[0005] Furthermore, the mold repair process generates a significant amount of waste, including metal debris and dust. Existing mold repair stations generally lack effective dust removal measures. This dust not only harms the respiratory system of operators, potentially leading to occupational illnesses through long-term exposure, but also pollutes the work environment, impacting the proper functioning of mold repair equipment. Dust can enter the equipment's transmission components, accelerating wear and reducing their lifespan. Furthermore, dust adheres to the mold surface, compromising mold repair precision and preventing the repaired mold from achieving the desired performance.

[0006] In summary, existing mold repair technologies have significant shortcomings in terms of multi-angle mold adjustment, stable clamping, and a clean work environment, failing to meet the requirements of modern precision mold repair for efficiency, accuracy, and safety. Therefore, developing a mold repair device that can achieve flexible multi-angle mold adjustment, stable clamping, and automatic dust removal is of great practical significance for improving mold repair quality, enhancing production efficiency, and improving the work environment. Summary of the Invention

[0007] The purpose of the present invention is to provide a multi-angle rotating mold repairing table, which realizes horizontal rotation through a rotating component, and completes vertical pitch adjustment by a cylinder-driven T-axis. The motor drives the guide clamping bracket to make the upper and lower rotating rollers clamp the mold and realize self-rotation. At the same time, the dust suction fan and the hollow groove cooperate to remove dust, and the lower rotating seat mounting hole fixes the equipment. All components work together to complete multi-angle precise mold repair.

[0008] To achieve the above object, the present invention provides the following technical solutions: A multi-angle rotating mold repairing table includes a base plate, characterized in that the base plate is fixedly mounted on a rotating assembly, rotating seats are symmetrically arranged on both sides of the base plate, an L-shaped mounting seat is rotatably mounted through the rotating seats, and the rotating seats are rotatably connected to the mounting seat bottom plate and the back plate at a vertical connection angle; A front baffle extends upward from the front side of the mounting seat bottom plate, a pair of parallel lower rotating rollers are rotatably installed between the front baffle and the mounting seat back plate, a pair of parallel sliding grooves are provided on the mounting seat back plate, a guide clamping bracket is provided on the rear side of the mounting seat back plate, a threaded groove is provided at the center of the guide clamping bracket, and the threaded groove passes through in the up and down directions; a sliding protrusion corresponding to the sliding groove is provided on the clamping bracket, the guide clamping bracket is slidably connected to the sliding groove through the sliding protrusion, and the sliding protrusion passes through the sliding groove and is rotatably installed with a pair of parallel upper rotating rollers on the front side of the mounting seat back plate; The mounting seat back plate is extended backward on both sides of the mounting seat back plate, and the mounting seat rear side plates are relatively parallel to each other above the mounting seat rear side plates on both sides. A T-shaped shaft is rotatably installed between the rotating holes on both sides, and the rotating holes on both sides are rotatably connected to the two ends of the top horizontal axis of the T-shaped shaft respectively. A cylinder is fixedly installed on the base plate at the rear side of the mounting seat bottom plate, and the telescopic end of the cylinder is rotatably connected to the bottom end of the vertical axis of the T-shaped shaft; A fixing plate is extended backward from the top of the back plate of the mounting seat, and a through hole is provided on the fixing plate. A motor is fixedly installed on the fixing plate. The motor is set downward, and a thread is provided on its rotating shaft. The rotating shaft of the motor passes through the through hole and is threadedly connected with a thread groove provided in the center of the guide clamping bracket.

[0009] When the mold's horizontal angle needs to be adjusted, the rotating assembly activates, driving the base plate to rotate about its vertical axis. To clamp the mold, the motor activates, rotating its rotating shaft. Due to the threaded engagement of the rotating shaft with the threaded groove of the guide clamping bracket, the guide clamping bracket moves downward along the sliding groove, gradually bringing the upper rotating roller closer to the lower rotating roller, thereby clamping the mold. During mold repair, the mold can be rotated while clamped by the rotation of the upper and lower rotating rollers, facilitating machining of various parts of the mold. To release the mold, the motor reverses, causing the guide clamping bracket to move upward, increasing the distance between the upper and lower rotating rollers and allowing the mold to be removed or repositioned. When the cylinder extends, it pushes the T-shaped shaft around the rotating hole. Due to the connection between the T-shaped shaft and the mounting bracket, the mounting bracket rotates upward about the mounting point on the rotating bracket, adjusting the mold's elevation angle. When the cylinder retracts, the mounting bracket rotates downward about the mounting point on the rotating bracket, adjusting the mold's depression angle. This structure allows for flexible vertical adjustment of the mold to meet diverse mold repair requirements.

[0010] The guide clamping bracket's two ends extend forward into a U-shape, with its two side arms clasping inward. Inside the clasping area, they are pivotally connected to the front ends of a pair of parallel upper rotating rollers. When the guide clamping bracket moves downward, driven by a motor, the U-shaped structure better withstands pressure, allowing the upper rotating rollers to evenly press against the mold, achieving stable clamping.

[0011] A dust extraction fan is fixedly mounted on the front side of the mounting base backplate. During mold repair, the fan activates, generating suction to draw dust and debris from the mold repair area into the fan, which is then discharged through a duct to a designated collection device. Because the fan is located close to the mold repair area, it effectively captures dust, reduces its spread in the air, and improves the quality of the working environment.

[0012] The rotating assembly comprises an upper rotating seat and a lower rotating seat. The base plate is fixedly mounted above the upper rotating seat. The upper and lower rotating seats are rotatably connected via bearings. The upper rotating seat is equipped with a locking mechanism. When the mold's horizontal angle needs to be adjusted, the operator manually rotates the upper rotating seat. Once the desired angle is reached, the locking mechanism locks the upper rotating seat to the lower rotating seat, allowing the mold to remain stably at that angle for mold repair.

[0013] The locking mechanism is achieved by providing a threaded hole in the upper rotating seat and an annular groove in the lower rotating seat corresponding to the threaded hole. The threaded hole threads into a locking bolt, and a truncated cone with a diameter larger than the annular groove is located on the bottom of the locking bolt. When adjusting the horizontal angle of the mold, the locking bolt is first loosened, allowing the upper rotating seat to rotate freely. Once the desired angle is reached, the locking bolt is tightened. The cone portion of the bolt gradually penetrates into the annular groove and contacts the bottom of the annular groove, generating a strong friction force that restricts the relative movement between the upper and lower rotating seats, thereby fixing the horizontal angle of the mold.

[0014] The top of the locking bolt is provided with a handle. By holding the handle, the operator can more conveniently apply torque to rotate the locking bolt. The inner surface of the circular cone at the bottom of the locking bolt is provided with anti-slip grooves. When the locking bolt is tightened, the anti-slip grooves on the inner surface of the cone contact the bottom of the annular groove, increasing the roughness of the contact surface and thus enhancing friction. Even during mold repair, which may result in vibration or external forces, the anti-slip grooves effectively prevent the locking bolt from loosening, ensuring that the mold angle is always maintained at the set position.

[0015] The base plate of the mounting base is provided with a hollowed-out groove. During the mold repair process, dust and debris generated naturally fall through the hollowed-out groove and fall into a collection device below the equipment. The hollowed-out groove also reduces the weight of the mounting base, making the entire mold repair platform more stable during rotation and operation, reducing the shaking and instability that may be caused by a high center of gravity.

[0016] The lower rotating base is provided with several mounting holes around its outer periphery. When installing the die-dressing platform, the platform is placed in a suitable location, and then bolts or other fasteners are passed through the mounting holes of the lower rotating base and tightened into corresponding screw holes on the ground or supporting structure to secure the platform to the tabletop.

[0017] The mounting base back plate is provided with an avoidance groove corresponding to the position of the cylinder telescopic axis. When the cylinder is extended or retracted, the telescopic axis will move within a certain range. The avoidance groove provides sufficient space for the telescopic axis to ensure that the cylinder can work normally and also ensure the structural integrity of the mounting base.

[0018] When the multi-angle rotating mold repair table is working, the upper and lower rotating seats of the rotating assembly are connected by bearings, which can drive the base plate and the overall structure to rotate horizontally. The locking bolts are screwed into the threaded holes of the upper rotating seat and matched with the annular grooves of the lower rotating seat to lock the horizontal angle; the cylinder telescopically drives the T-shaped shaft to rotate around the rotating hole of the rear side plate of the mounting seat, driving the L-shaped mounting seat to rotate around the connection point of the rotating seat to complete the pitch angle adjustment of the mold in the vertical direction; the motor rotating shaft cooperates with the threaded groove of the guide clamping bracket to drive the bracket to move up and down along the sliding groove, so that the upper and lower rotating rollers clamp the mold. At the same time, the mold can rotate around its own axis in the clamped state to achieve all-round operation; the dust suction fan promptly removes the dust generated by mold repair, the hollow groove of the mounting seat bottom plate assists the dust to fall, and the lower rotating seat mounting through-hole can fix the equipment to ensure stable operation. The coordinated operation of various components can realize multi-angle and precise mold repair of the mold.

[0019] Compared with the prior art, the present invention has the following beneficial effects: Comprehensive and Flexible Adjustment: Traditional mold repair tables only hold molds in place, requiring operators to frequently adjust their positions and postures to inspect different parts of the mold, resulting in low efficiency and high labor intensity. However, the present invention utilizes a rotating assembly that allows for free horizontal rotation, while a cylinder-driven T-shaft drives the mounting base for vertical pitch adjustment, enabling the mold to be adjusted to any desired angle within a given space. Whether the mold's top surface, side surfaces, or complex internal structures, the operator can adjust it to the most convenient position, greatly improving the flexibility and convenience of mold repair operations.

[0020] Efficient and stable clamping and rotation: Existing mold fixing methods often find it difficult to balance clamping stability and mold rotation requirements. In the present invention, a motor drives the guide clamping bracket, and the upper and lower rotating rollers achieve precise clamping of the mold through threaded transmission. This clamping method not only has uniform force and can adapt to molds of different sizes and shapes, but also, in the clamped state, the mold can still rotate freely through the rotating rollers, making it convenient for operators to continuously process various surfaces of the mold without the need to repeatedly disassemble and re-fix the mold, greatly improving the efficiency of mold repair. At the same time, the U-shaped structural design of the guide clamping bracket enhances the overall rigidity, ensuring that the mold remains stable during the mold repair process, avoiding processing errors caused by insufficient or uneven clamping force.

[0021] A good working environment is guaranteed: A large amount of dust is generated during the mold repair process. Most existing mold repair equipment lacks effective dust removal measures. Dust not only endangers the health of operators, but also easily adheres to the mold surface, affecting mold repair accuracy and mold quality. The present invention provides a dust suction fan on the front side of the mounting seat back plate, which can promptly remove dust generated during the mold repair process. At the same time, the hollow groove design of the mounting seat bottom plate allows dust to fall directly, and cooperates with the dust suction fan to form a dual dust removal effect, effectively keeping the work area clean, creating a healthy working environment for operators, and also providing a guarantee for high-quality mold repair.

[0022] Precise angle locking and stable support: For mold repair operations, precise locking of the mold angle is crucial. Traditional equipment is often not precise enough in angle fixing, and angle deviation is prone to occur, which affects the accuracy of mold repair. The locking mechanism of the present invention cooperates with threaded holes, annular grooves and locking bolts with anti-slip patterns to achieve precise locking of the angle between the upper rotating seat and the lower rotating seat. Even under long-term mold repair or under certain external forces, the mold angle can be kept stable, thereby ensuring the high-precision requirements of mold repair. In addition, the mounting holes around the outer edge of the lower rotating seat can firmly fix the mold repair table to the workplace, which is more stable than traditional equipment and reduces safety hazards and processing errors caused by equipment shaking.

[0023] Wide Applicability and Scalability: The structural design of this invention fully considers the needs of different mold repairing types. Its multi-angle adjustment and flexible clamping functions are suitable for molds of various shapes, sizes, and materials. Furthermore, the modular design of this mold repair station provides excellent scalability. Auxiliary lighting and detection devices can be added as needed to further enhance its functionality and application range. Compared with traditional single-function mold repair equipment, this device has stronger market competitiveness and broader application prospects. BRIEF DESCRIPTION OF THE DRAWINGS

A motor 6 is fixedly installed on the fixing plate 26. The motor 6 is set downward, and a thread is provided on its rotating shaft. The rotating shaft of the motor 6 passes through the through hole and is threadedly connected with a thread groove 32 provided in the center of the guide clamping bracket 3.

[0027] The two ends of the guide clamping bracket 3 extend forward in a U shape, and the two side arms thereof embrace inwardly and are rotatably connected to the front ends of a pair of parallel upper rotating rollers 22 at the inner side of the embrace.

[0028] A dust suction fan 7 is fixedly mounted on the front side of the back plate of the mounting base 2 .

[0029] The rotating assembly 6 includes an upper rotating seat 61 and a lower rotating seat 62. The base plate 1 is fixedly installed above the upper rotating seat 61. The upper rotating seat 61 and the lower rotating seat 62 are rotatably connected via a bearing. A locking mechanism is provided on the upper rotating seat 61.

[0030] The locking mechanism is achieved by setting a threaded hole 63 on the upper rotating seat 61 and setting an annular groove 64 on the lower rotating seat 62 at the position corresponding to the threaded hole 63. The threaded hole 63 is threaded to fit through a locking bolt 65, and the locking bolt 65 is located on the bottom side and has a cone with a diameter larger than the annular groove 64.

[0031] A handle 65 is provided on the top of the locking bolt 65 .

[0032] The inner surface of the bottom cone of the locking bolt 65 is provided with anti-slip lines.

[0033] A hollow groove is provided on the bottom plate of the mounting seat 2 .

[0034] A plurality of mounting holes 66 are provided around the outer edge of the lower rotating seat 62 .

[0035] The back plate of the mounting seat 2 is provided with an avoidance groove corresponding to the telescopic axis position of the cylinder 5 .

[0036] In Example 1, first, the mold repairing table is fixed to a flat and stable work site with bolts through the mounting holes 66 around the outer edge of the lower rotating seat 62 to ensure that the equipment will not be displaced during subsequent operations; then, the motor 6 is started to reverse, and the rotating shaft of the motor 6 is threadedly engaged with the threaded groove 32 in the center of the guide clamping bracket 3, driving the guide clamping bracket 3 to move upward along the sliding groove 23, so that the distance between the upper rotating roller 22 and the lower rotating roller 22 is increased. At this time, the mold is placed stably on the lower rotating roller 22, and its back is against the back plate of the mounting seat 2 and against the front baffle 21. Then the motor 6 is started to rotate forward, the guide clamping bracket 3 moves downward, and the upper and lower rotating rollers 22 clamp the mold. The mold is ensured to be firm and centered through observation and measurement.

[0037] When the cam 61 is in the air, the upper and lower cams 62 are in the air, and the cam 63 is in the air, and the cam 64 is in the air, and the cam 65 is in the air, and the cam 66 is in the air, and the cam 67 is in the air, and the cam 68 is in the air, and the cam 69 is in the air, and the cam 69 is in the air, and the cam 67 is in the air, and the cam 68 is in the air, and the cam 69 is in the air, and the cam 68 ...

[0038] During the mold repair phase, the dust suction fan 7 on the front side of the back plate of the mounting base 2 is started to create negative pressure around the mold, promptly removing dust and debris generated by the mold repair. The hollow grooves of the bottom plate of the mounting base 2 are used to allow the dust to fall and be discharged smoothly. Based on the mold repair requirements, the operator utilizes the freely rotatable upper and lower rotating rollers 22 to manually rotate the mold and perform fine operations such as grinding, polishing, and repair welding on various parts of the mold. During the process, the horizontal or vertical angle can be adjusted again according to actual needs. After the mold repair is completed, the motor 6 is started in reverse, so that the guide clamping bracket 3 drives the upper rotating roller 22 upward, loosens the mold, and removes the mold from the mold repair table. The power is turned off and the dust suction fan 7 filter and the debris in the hollow groove are cleaned to prepare for the next use.

[0039] Example 2 provides that when the cylinder 5 contracts, the T-shaped shaft 4 is pulled to rotate around the rotating hole 25 of the rear side plate 24 of the mounting seat. Due to the connection between the T-shaped shaft 4 and the mounting seat 2, the mounting seat 2 is driven to rotate upward around the rotating seat 11 to achieve the mold elevation angle adjustment. When the cylinder 5 extends, the mounting seat 2 rotates downward to complete the depression angle adjustment, and the reverse operation process is installed through the installation position of the cylinder.
