Description

Technical Field

[0001] This invention relates to the field of mold processing technology, specifically to a tilted, one-time forming mold with a tilted head. Background Technology

[0002] Molding dies are core process equipment in industrial manufacturing used for one-time forming of workpieces. They are widely used in the mass production of various irregularly shaped workpieces, such as automotive parts, home appliance structural components, and daily-use plastic products. Among them, tilting molds with tilting forming function are a special type of mold adapted to the forming of complex inclined surfaces and irregular curved surfaces. Existing molds of this type typically include a mold body frame, worktable, forming mold frame, mold base, drive transmission mechanism, forming execution components, and other basic structures. Through matching transmission and adjustment structures, the tilting angle of the mold can be adapted, and multiple forming actions such as bending, pressing, and trimming of workpieces can be completed in a single processing operation without multiple mold changes and repeated clamping. These processing molds can recycle plastic waste and can adapt to the processing needs of plastic and hardware workpieces of different specifications and forming angles. They are commonly used basic equipment in industries such as plastic recycling and hardware auto parts manufacturing to ensure the forming accuracy of workpieces and improve the efficiency of mass production.

[0003] In the current application of molding dies used for plastic processing and plastic waste recycling, there are still some significant limitations. The main body of these dies is mostly made of non-metallic substrates. Due to the surface characteristics of these substrates and the limitations of the existing molding structure, the plastic workpieces after molding are very prone to sticking to the inner wall of the mold cavity. It is difficult to achieve smooth demolding between the workpiece and the mold, which not only increases the difficulty of molding operations, but also easily causes deformation and damage to the workpiece during demolding, directly affecting the processing qualification rate of finished products and overall production efficiency. Summary of the Invention

[0004] Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a tilted, one-time molding die that solves the problems of plastic workpieces easily sticking to the mold cavity, making demolding difficult, and consequently resulting in low finished product qualification rate and low production efficiency.

[0005] Technical solution To achieve the above objectives, the present invention provides the following technical solution: A tilting, one-time molding die includes a die body with a frame housing inside. A worktable is provided on the surface of the die body, and a die frame is mounted on the worktable. A die base is slidably connected inside the die body. The die body also includes a linear actuator for scraping the inner wall of the die frame; a lifting assembly for raising and lowering the die base; and an adjustable movable assembly for adjusting the die base. The linear actuator includes a motor mounted on the outer wall of the worktable. A cam is mounted on the surface of the motor's output shaft, and a connecting rod is hinged to the surface of the cam. A sliding seat is hinged to the end of the connecting rod away from the cam. A slide rail is mounted on the surface of the worktable, and the sliding seat is slidably connected inside the slide rail. A spring is mounted on the surface of the sliding seat, and a scraper is mounted on the outer side of the spring.

[0006] Preferably, the surface of the sliding seat is provided with a groove, one end of the spring is fixedly installed on the surface of the sliding seat, and the other end of the spring passes through the groove.

[0007] Preferably, the lifting assembly includes a drive wheel, which is mounted on the surface of the motor output shaft. The drive wheel is connected to a drive shaft via a belt, and the drive shaft is rotatably connected inside the frame housing.

[0008] Preferably, a gear is connected to the surface of the drive shaft, and a lifting rod is slidably connected inside the frame housing. The lifting rod has a toothed surface, and the gear meshes with the toothed surface of the lifting rod.

[0009] Preferably, the adjustable movable component includes a base mounted on top of the lifting rod.

[0010] Preferably, a power gear is rotatably connected to the surface of the base, the teeth of the power gear mesh with a rack, and the rack is slidably connected inside the frame housing.

[0011] Preferably, the outer side of the power gear is connected to an active crank, and a connecting arm is hinged to the end of the active crank away from the power gear. The end of the connecting arm away from the active crank is hinged to the bottom of the mold base.

[0012] Preferably, a driven seat is rotatably connected to the surface of the base, and the top of the driven seat is fixedly connected to the bottom of the mold base.

[0013] Preferably, a limiting plate is installed on the surface of the base, and the bottom of the driven seat is adapted to the limiting surface of the limiting plate.

[0014] Beneficial effects Compared with the prior art, the present invention provides a tilted, one-time forming mold with the following advantages: 1. By setting up linear execution components, the molten plastic residue, overflow waste, and carbonized deposits attached to the inner wall of the mold frame can be automatically scraped and cleaned after each molding operation. The scraping action is precisely synchronized with the end point of the molding process, eliminating the need for manual shutdown and tedious cavity cleaning inside the equipment. Furthermore, the purely mechanical linkage drive method does not require additional independent power sources and electrical control systems, resulting in a simple and reliable structure. During operation, no complex parameter adjustments are required, achieving the effects of continuously maintaining the smoothness of the inner wall of the mold cavity, reducing the probability of workpiece adhesion to the mold from the source, preventing residual residue from affecting the molding accuracy of subsequent workpieces, reducing the labor intensity of operators, improving the continuous production capacity of the equipment, extending the overall service life of the mold, and reducing the daily maintenance costs of the equipment.

[0015] 2. By setting up the lifting components, the mold base can drive the molded workpiece to complete a smooth vertical lifting motion. During the lifting process, the force on each part is uniform and there is no eccentric load. The lifting parameters can be precisely controlled according to the molding requirements of different workpieces. The lifting action can be seamlessly connected with the subsequent adjustment action and the cleaning action of the linear actuator. The action sequence is precisely matched without conflict. This achieves the effect of completing multi-process continuous processing of the workpiece in conjunction with the subsequent molding process, while realizing the automatic separation and demolding of the workpiece from the mold frame, avoiding damage to the workpiece caused by uneven force during manual demolding, greatly improving the finished product qualification rate, reducing impact wear during the mold opening and closing process, and improving the overall operational stability of the equipment.

[0016] 3. By setting up adjustable movable components, the mold base can drive the workpiece to complete continuous adjustment within a preset range. The adjustment parameters can be accurately matched according to the molding requirements of different workpieces and maintained stably in any state. The adjustment process is smooth and stable without jamming or shaking. Moreover, the adjustment action can be coordinated with the action of the lifting component to complete the composite molding action. No additional auxiliary mechanisms are required. This achieves the effect of completing the one-time molding of various irregular workpieces in a single processing step, eliminating the need for multiple mold changes and repeated clamping, significantly shortening the workpiece processing cycle and improving the equipment's versatility and adaptability. At the same time, it optimizes the flow and filling effect of molten plastic in the cavity, reduces various molding defects, improves the consistency of workpiece molding, and reduces the cost of mold development and production.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1-7 A tilting, one-time molding die includes a die body 1, an internal frame housing 12, a worktable 13 on the surface of the die body 1, a die frame 14 mounted on the surface of the worktable 13, and a die base 15 slidably connected inside the die body 1. It also includes a linear actuator 2 for scraping the inner wall of the die frame 14; a lifting assembly 3 for raising and lowering the die base 15; and an adjustable movable assembly 4 for adjusting the die base 15. First, the linear actuator 2 includes a motor 21, which is mounted on the outer wall of the worktable 13. A cam 22 is mounted on the surface of the output shaft of the motor 21, and a connecting rod 23 is hinged to the surface of the cam 22. A sliding seat 24 is hinged to the end of the connecting rod 23 away from the cam 22. A slide rail 25 is mounted on the surface of the worktable 13, and the sliding seat 24 is slidably connected inside the slide rail 25. A spring 26 is mounted on the surface of the sliding seat 24, and a scraper 27 is mounted on the outer side of the spring 26. The constant rotational power output by the motor 21 drives the cam 22 to rotate synchronously. During the rotation of the cam 22, its eccentric wheel... First, the cam 22 presses down on the spring piece 26, pressing it into the corresponding groove 241 of the sliding seat 24, so that the spring piece 26 and the sliding seat 24 form a rigid connection for synchronous movement. Then, the cam 22 drives the sliding seat 24 to make a directional linear movement parallel to the side of the mold frame 14 along the slide rail 25 through the connecting rod 23. The spring piece 26 moves synchronously with the sliding seat 24, thereby driving the scraper 27 to complete the scraping and cleaning action on the side of the mold frame 14. When the cam 22 continues to rotate, it first releases the pressure on the spring piece 26, and then drives the sliding seat 24 to reset through the connecting rod 23, completing a complete work cycle.

[0021] Secondly, a groove 241 is provided on the surface of the sliding seat 24. One end of the spring piece 26 is fixedly installed on the surface of the sliding seat 24, and the other end of the spring piece 26 passes through the groove 241. The groove 241 provides a precise receiving space and positioning reference for the cam 22 to press the spring piece 26. When the cam 22 presses the spring piece 26 into the groove 241, the inner wall of the groove 241 can form a circumferential constraint on the spring piece 26, preventing the spring piece 26 from shifting or shaking during the movement of the sliding seat 24, thus ensuring the movement trajectory and cleaning accuracy of the scraper 27. At the same time, this through-type installation structure allows the spring piece 26 to be fixed at only one end for stable installation, simplifying the overall assembly structure and facilitating the individual replacement and maintenance of the spring piece 26 and the scraper 27 in the future.

[0022] Furthermore, the lifting assembly 3 includes a transmission wheel 31, which is mounted on the surface of the output shaft of the motor 21. The transmission wheel 31 is connected to a transmission shaft 32 via a belt, and the transmission shaft 32 is rotatably connected inside the frame housing 12. The transmission wheel 31 rotates synchronously with the output shaft of the motor 21, and transmits power synchronously to the transmission shaft 32 via belt drive. Belt drive has a natural buffering and shock absorption effect, which can effectively reduce vibration and operating noise during transmission. At the same time, it can slip in the event of accidental overload, providing overload protection for the motor 21 and all subsequent transmission components. The transmission shaft 32 transmits power to the transmission mechanism inside the frame housing 12, providing a stable power input for the lifting action of the lifting rod 34.

[0023] Furthermore, a gear 33 is connected to the surface of the drive shaft 32, and a lifting rod 34 is slidably connected inside the frame housing 12. The surface of the lifting rod 34 is provided with teeth, and the gear 33 meshes with the teeth of the lifting rod 34. The drive shaft 32 drives the gear 33 to rotate synchronously. The gear 33 transmits the rotational motion precisely into the vertical linear motion of the lifting rod 34 through meshing with the teeth of the lifting rod 34. This type of transmission has the characteristics of high transmission accuracy, strong load-bearing capacity, and smooth, backlash-free movement. It can precisely control the lifting stroke and lifting speed of the lifting rod 34, ensuring the synchronicity and accuracy of the lifting process of the mold base 15 and avoiding tilting and deformation of the workpiece due to asynchronous lifting.

[0024] Furthermore, the adjustable movable component 4 includes a base 41, which is mounted on top of the lifting rod 34. The base 41 moves vertically in sync with the lifting rod 34, providing a unified mounting base and rigid support for all other components of the adjustable movable component 4. It synchronously transmits the power of the lifting component 3 to the adjustable movable component 4, while ensuring that the relative position of the adjustable movable component 4 with the mold base 15 remains stable during the lifting process, providing a reliable support reference for subsequent adjustment actions.

[0025] Furthermore, a power gear 42 is rotatably connected to the surface of the base 41, and the teeth of the power gear 42 mesh with a rack 43, which is slidably connected inside the frame housing 12. When the base 41 moves up and down with the lifting rod 34, the power gear 42 rolls along the rack 43 fixed inside the frame housing 12. The meshing transmission between the rack 43 and the power gear 42 converts the vertical linear motion of the lifting rod 34 into the rotational motion of the power gear 42. This structure can realize the power input of the adjustable movable component 4 without the need for an additional independent power source, realizing the mechanical linkage between the lifting action and the adjustment action, greatly simplifying the overall structure of the equipment, and reducing the manufacturing cost and operating energy consumption of the equipment.

[0026] Furthermore, a drive crank 44 is connected to the outer side of the drive gear 42. A connecting arm 45 is hinged to the end of the drive crank 44 away from the drive gear 42, and the end of the connecting arm 45 away from the drive crank 44 is hinged to the bottom of the mold base 15. The drive crank 44 rotates synchronously with the drive gear 42, converting the rotational motion of the drive gear 42 into the reciprocating swing of the connecting arm 45. The connecting arm 45 then pushes the mold base 15 to swing and adjust around the rotational connection point of the driven seat 46. This mechanism has the characteristics of smooth movement, reliable force transmission, and torque amplification. It can convert a small rotational torque into a large thrust, ensuring that the mold base 15 can still achieve smooth and reliable adjustment while bearing the weight of the workpiece.

[0027] Furthermore, a driven seat 46 is rotatably connected to the surface of the base 41, and the top of the driven seat 46 is fixedly connected to the bottom of the mold base 15. The driven seat 46 provides a stable rotational support point for the mold base 15, enabling the mold base 15 to swing smoothly around this support point. At the same time, the fixed connection between the driven seat 46 and the mold base 15 ensures that there will be no relative displacement between the two during movement, ensuring the adjustment accuracy and load-bearing capacity of the mold base 15, and providing a stable support platform for the forming of the workpiece.

[0028] Finally, a limiting plate 47 is installed on the surface of the base 41, and the bottom of the driven seat 46 is adapted to the limiting surface of the limiting plate 47. The limiting plate 47 precisely mechanically limits the rotation range of the driven seat 46, preventing the adjustment range of the mold base 15 from exceeding the preset range, and avoiding workpiece forming defects or equipment component collision damage due to over-adjustment; at the same time, the limiting surface of the limiting plate 47 can provide auxiliary support for the driven seat 46, further improving the stability of the mold base 15 during the adjustment process, and ensuring the accuracy and batch consistency of workpiece forming.

[0029] Working principle: When the equipment is running, the motor 21 installed on the outer wall of the worktable 13 of the processing mold body 1 is started. The output shaft of the motor 21 outputs constant rotational power, which synchronously drives the cam 22 and the transmission wheel 31 to rotate. When the cam 22 rotates to the pressing position, its outer edge presses down on the spring piece 26, pressing the spring piece 26 into the groove 241 on the surface of the sliding seat 24, so that the spring piece 26 and the sliding seat 24 form a rigid synchronous connection. At the same time, the cam 22 drives the sliding seat 24 to make a directional linear movement parallel to the side of the mold frame 14 along the slide rail 25 on the worktable 13 through the hinged connecting rod 23. This drives the scraper 27 installed on the outside of the spring piece 26 to complete the scraping and cleaning operation on the side of the mold frame 14. Meanwhile, the transmission wheel 31 transmits power to the transmission shaft 32 inside the frame housing 12 through the belt. The transmission shaft 32 drives the gear 33 on its surface to rotate synchronously. The gear 33 transmits the rotational motion through the meshing of the tooth surface on the surface of the lifting rod 34. The vertical linear motion of the lifting rod 34 is converted into the synchronous lifting and lowering of the base 41 installed on the top of the lifting rod 34. During the lifting and lowering process of the base 41, the power gear 42 rotatably connected to its surface rolls along the rack 43 fixed inside the frame housing 12, converting the vertical lifting and lowering motion of the base 41 into the rotational motion of the power gear 42. The power gear 42 synchronously drives the active crank 44 on its outer side to rotate. The active crank 44 pushes the mold base 15 to rotate around the driven seat 46 on the base 41 through the hinged connecting arm 45. The limiting plate 47 installed on the surface of the base 41 precisely limits the rotation range of the driven seat 46, completing the adjustment action of the mold base 15. When the cam 22 rotates to the reset position, its outer edge contour releases the downward pressure constraint on the spring 26. At the same time, the sliding seat 24 is driven to return to the initial position along the slide rail 25 through the connecting rod 23. The lifting assembly 3 and the adjustable movable assembly 4 also synchronously complete the reset action, thus completing a complete work cycle.
