Description

Technical Field

[0001] The invention relates to the technical field of shoe sole injection molding machine equipment, and in particular to a waste material clamping and coding device for a shoe sole injection molding machine and a use method thereof. Background Art

[0002] In the field of shoe sole injection molding production, traditional waste disposal often relies on manual labor. For example, workers manually remove the soles from the mold, separate the waste, and then sort and stack them by size. This method has the disadvantages of low efficiency, high error rate, and high labor intensity. Although existing automated equipment can partially replace manual labor, the following problems are common: insufficient mold switching flexibility makes it difficult to adapt to the production of multiple shoe sole specifications; waste is prone to falling off during clamping due to unstable adsorption; and the classification accuracy of the coding mechanism is limited, still requiring manual re-inspection. In addition, the traditional equipment has a loose structure and poor coordination between the various functional modules (such as mold opening, clamping, and coding), resulting in longer production cycles.

[0003] A Chinese patent discloses a trimming device for a sole injection molding machine, publication number: (CN 214982730 U), which includes a bearing base plate and injection molds welded to both sides of the top of the bearing base plate. The characteristics are: a vertical frame is welded symmetrically front and back on the middle position of the bearing base plate, and vertical plates are welded to both ends of the top of the bearing base plate. A linear slide rail is fixedly installed on the inner side of the two vertical plates. A scraper is slidably connected between the two linear slide rails through a group of U-shaped sliders. The scraper is driven to slide by a driving mechanism. However, the automation equipment of the trimming device for the sole injection molding machine is inefficient, and has the defects of poor flexibility, inaccurate classification, and low collaborative efficiency. Therefore, a waste clamping and coding device for a sole injection molding machine and a method for using the same are needed. Summary of the Invention

Intelligent unloading: The servo motor and the connecting rod mechanism cooperate to adjust the flip angle to adapt to different waste weight distributions; anti-accumulation design: The material discharge chute and the flip plate are linked to ensure that the waste is completely separated from the equipment.

[0014] Preferred: (1) Top mold stage (initial mold separation) When the mold rotates to the top mold position, the top mold cylinder is first started to push the top mold moving part forward, so that the pressure block presses the third mold rod and locks the position of the middle frame mold. Shock-absorbing springs are arranged on both sides of the top mold cylinder to effectively absorb the impact force when the mold is opened. Then the lifting cylinder is activated to lift the lower two demolding molds about 10-15mm through the lifting plate. The lifting plate is driven by the lifting cylinder and applies a uniform lifting force from the bottom of the mold to initially separate the lower two demolding molds from the middle frame mold. (2) Mold re-opening stage (mold fully opened) After the mold is ejected, the lifting cylinder controls the vertical movement of the sliding block through the lifting linear guide rail, driving the first mold hook to achieve precise positioning. The lifting cylinder drives the sliding block downward, allowing the first mold hook to accurately hook the third mold rod of the middle frame mold; at the same time, the servo motor drives the mold flipping rack, driving the entire mold flipping bracket to rotate 55-75 degrees, completely flipping the middle frame mold. At the same time, the second mold hook moves synchronously to hook the second mold rods of the upper two demolding molds, ensuring that the two parts of the mold are completely separated; (3) Suction cup clamping stage When the mold is fully opened, the support beam is driven to move along the main linear guide rail to the top of the sole mold according to the preset program. Then, the support beam is driven to move along the long guide rail to the position directly above the mold. The slider drives the connecting bracket to perform position compensation. At the same time, the bottom fixture bracket on the short guide rail is finely adjusted to make the suction cup model evenly distributed at the optimal force position on the sole. The vacuum system is started for pre-adsorption testing (reaching a negative pressure of 30kPa within 0.5 seconds). After confirming that all suction cups are well sealed, the suction cup assembly moves the sole workpiece along the main linear guide rail to the mounting plate unloading chute position. (4) Waste clamping stage After the suction cup transports the sole workpiece to the transition station, the driving motor drives the sliding seat to accurately position it through the transmission shaft. At the same time, the double-rod cylinder of the clamping assembly extends and performs three-dimensional positioning of the sole workpiece through the H-shaped positioning block to ensure that the workpiece does not move during the clamping process. Then the driving motor drives the sliding seat to move along the guide rail through the transmission shaft, and the clamping cylinder is started to drive the clamping jaws to extend and retract, so that the clamping block on the clamping jaws is accurately aligned with the edge of the waste material. (5) Code segmentation stage When the sole workpiece arrives at the coding station, the preset program accurately determines the workpiece code through the visual recognition system. The first servo motor drives the coding frame to move along the first linear guide to the station of the corresponding code. At the same time, the second servo motor starts to drive the mounting plate to accurately position along the third linear guide. The second servo motor drives the mounting plate to move along the third linear guide to the predetermined position. At this time, the connecting rod mechanism pushes the flip plate to complete a 90° flip to form an inclined guide surface. After the sole workpiece slides smoothly into the coding frame along the flip plate, the single-rod cylinder moves quickly to push (or drive by flipping) the coding plate with a through groove to accurately guide the workpiece into the specified code partition plate.

[0015] The present invention is beneficial in that: This application uses modular collaborative design of waste material clamping and coding equipment to achieve automated separation, precise clamping, and intelligent classification of waste materials during the sole injection molding production process. Its core advantages are: Efficient and continuous production: The rotating disc and the multi-station mold slot ensure seamless integration of injection molding, mold opening, waste separation, and coding processes, significantly reducing downtime caused by traditional manual intervention and improving overall production efficiency. Accurate waste handling: The mold opening device (top mold + mold turning component) is linked with the suction cup component to ensure that waste is automatically separated from the sole mold during the demoulding stage, avoiding errors or damage caused by manual cleaning; the inclined baffle of the coding frame works together with the servo-driven coding plate to automatically collect waste by code number, with high classification accuracy.

[0016] Equipment compatibility and stability: The modular mold design (upper two-part mold, middle frame mold, lower two-part mold) adapts to different sole structures. The adjustable bracket and vacuum adsorption system of the suction cup assembly can stably grasp various types of waste. The multiple support rods and shock-absorbing spring design effectively resist vibration interference during equipment operation and extend the life of key components.

[0017] Space and manpower optimization: The integrated layout concentrates mold opening, clamping, and coding functions on the main support frame. The equipment has a compact structure and is easy to integrate into existing production lines, while significantly reducing dependence on skilled operators. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] In the present embodiment: (1) Top mold stage (initial mold separation) When the mold rotates to the top mold position, the top mold cylinder 38 is first started to push the top mold moving part 34 forward, so that the pressure block 35 presses the third mold rod 16 and locks the position of the middle frame mold 12. The shock-absorbing springs 39 are arranged on both sides of the top mold cylinder 38 to effectively absorb the impact force when the mold is opened. Then the lifting cylinder 37 is activated to lift the lower two demolding molds 13 by about 10-15mm through the lifting plate 36. The lifting plate 36 is driven by the lifting cylinder 37 to apply a uniform lifting force from the bottom of the mold to initially separate the lower two demolding molds 13 from the middle frame mold 12. (2) Mold re-opening stage (mold fully opened) After the mold is ejected, the lifting cylinder 29 controls the vertical movement of the sliding block through the lifting linear guide rail, driving the first mold hook 33 to achieve precise positioning. The lifting cylinder 29 drives the sliding block to move downward, so that the first mold hook 33 accurately hooks the third mold rod 16 of the middle frame mold 12; at the same time, the servo motor drives the mold flipping rack 23, driving the entire mold flipping bracket 28 to rotate 55-75 degrees, completely flipping the middle frame mold 12. At the same time, the second mold hook 32 moves synchronously to hook the second mold rod 15 of the upper two demolding molds 11, ensuring that the two parts of the mold are completely separated; (3) Suction cup clamping stage When the mold is fully opened, the support beam 40 is driven to move along the main linear guide rail 4 to above the sole mold according to the preset program, and then the support beam 40 is driven to move along the long guide rail 43 to the position directly above the mold. The slider 42 drives the connecting bracket 41 to perform position compensation. At the same time, the bottom fixture bracket 52 on the short guide rail 46 is finely adjusted to make the suction cup model 51 evenly distributed at the optimal force position on the sole. The vacuum system is started to perform pre-adsorption detection (reaching a negative pressure of 30kPa within 0.5 seconds). After confirming that all suction cups are well sealed, the suction cup assembly moves the sole workpiece 68 along the track of the main linear guide rail 4 to the position of the mounting plate unloading chute; (4) Waste clamping stage After the suction cup transports the sole workpiece 68 to the transition station, the driving motor 63 drives the sliding seat 62 to accurately position it through the transmission shaft. At the same time, the double-rod cylinder 73 of the clamping assembly extends and performs three-dimensional positioning of the sole workpiece 68 through the H-shaped positioning block 69 to ensure that the workpiece does not move during the clamping process. Then the driving motor 63 drives the sliding seat 62 to move along the guide rail through the transmission shaft, and the clamping cylinder 65 is started to drive the clamping jaws 66 to extend and retract, so that the clamping block 67 on the clamping jaws 66 is accurately aligned with the edge of the waste. (5) Code segmentation stage When the sole workpiece 68 arrives at the coding station, the preset program accurately determines the workpiece code through the visual recognition system. The first servo motor 55 drives the coding frame 18 to move along the first linear guide 56 to the station of the corresponding code. At the same time, the second servo motor 80 is started to drive the mounting plate to be precisely positioned along the third linear guide 75. The second servo motor 80 drives the mounting plate to move to the predetermined position along the third linear guide 75. At this time, the connecting rod mechanism 76 pushes the flip plate 72 to complete a 90° flip to form an inclined guide surface. After the sole workpiece 68 slides smoothly into the coding frame 18 along the flip plate 72, the single-rod cylinder 19 moves quickly to push (or drive by flipping) the coding plate 21 with the through groove 20 to accurately guide the workpiece into the specified code partition plate 25.

10. A method for using the waste material clamping and coding device for a shoe sole injection molding machine according to claim 1: (1) Top mold stage (initial mold separation) When the mold rotates to the top mold position, the top mold cylinder (38) is first started to push the top mold moving part (34) forward, so that the pressure block (35) presses the third mold rod (16) and locks the position of the middle frame mold (12). The shock-absorbing springs (39) are arranged on both sides of the top mold cylinder (38) to effectively absorb the impact force when the mold is opened. Then the lifting cylinder (37) is activated to lift the lower two demolding molds (13) by about 10-15 mm through the lifting plate (36). The lifting plate (36) is driven by the lifting cylinder (37) to apply a uniform lifting force from the bottom of the mold to initially separate the lower two demolding molds (13) from the middle frame mold (12); (2) Mold re-opening stage (mold fully opened) After the top mold is completed, the lifting cylinder (29) controls the vertical movement of the sliding block through the lifting linear guide rail, driving the first mold hook (33) to achieve precise positioning, and the lifting cylinder (29) drives the sliding block to move downward, so that the first mold hook (33) accurately hooks the third mold rod (16) of the middle frame mold (12); at the same time, the servo motor drives the mold turning rack (23) to drive the entire mold turning bracket (28) to rotate 55-75 degrees, and the middle frame mold (12) is completely turned over. At the same time, the second mold hook (32) moves synchronously to hook the second mold rod (15) of the upper two demolding molds (11) to ensure that the two parts of the mold are completely separated; (3) Suction cup clamping stage When the mold is fully opened, the support beam (40) is driven to move along the main linear guide rail (4) to the top of the sole mold according to the preset program, and then the support beam (40) is driven to move along the long guide rail (43) to the position directly above the mold, and the slider (42) drives the connecting bracket (41) to perform position compensation. At the same time, the bottom fixture bracket (52) on the short guide rail (46) is finely adjusted so that the suction cup model (51) is evenly distributed at the optimal force position of the sole. The vacuum system is started to perform pre-adsorption detection (reaching a negative pressure of 30kPa within 0.5 seconds). After confirming that all suction cups are well sealed, the suction cup assembly moves the sole workpiece (68) along the main linear guide rail (4) track to the mounting plate unloading trough position; (4) Waste clamping stage After the suction cup transports the sole workpiece (68) to the transition station, the driving motor (63) drives the sliding seat (62) to accurately position it through the transmission shaft. At the same time, the double-rod cylinder (73) of the clamping assembly extends and three-dimensionally positions the sole workpiece (68) through the H-shaped positioning block (69) to ensure that the workpiece does not move during the clamping process. Then, the driving motor (63) drives the sliding seat (62) to move along the guide rail through the transmission shaft, and the clamping cylinder (65) is started to drive the clamping claw (66) to extend and retract, so that the clamping block (67) on the clamping claw (66) is accurately aligned with the edge of the waste material; (5) Code segmentation stage When the sole workpiece (68) arrives at the code division station, the preset program accurately determines the workpiece code number through the visual recognition system, and the first servo motor (55) drives the code division frame (18) to move along the first linear guide rail (56) to the workstation corresponding to the code number. At the same time, the second servo motor (80) is started to drive the mounting plate to accurately position along the third linear guide rail (75). The second servo motor (80) drives the mounting plate to move along the third linear guide rail (75) to a predetermined position. At this time, the connecting rod mechanism (76) drives the flip plate (72) to complete a 90° flip to form an inclined guide surface. After the sole workpiece (68) slides smoothly into the code division frame (18) along the flip plate (72), the single-rod cylinder (19) moves quickly to push (or drive by flipping) the code division plate (21) with the through slot (20) to accurately guide the workpiece into the specified code number partition plate (25).
