A molding die for 3C electronic product casings

Abstract

This utility model relates to a 3C electronic product shell molding mold applied in the field of mold manufacturing technology. It realizes the process of placing the electronic product component on a pressure plate within a tray, then using a controller to activate a hydraulic cylinder to drive the upper mold to stamp the electronic product component. After stamping, an electric push rod is activated to push the pressure plate upwards. A removable protective sleeve is fitted onto the surface of the pressure plate. As the pressure plate moves upwards, rollers on the sidewall of the protective sleeve roll synchronously upwards within a groove, reducing friction with the inner wall of the lower mold. When the pressure plate pushes the formed product shell outside the lower mold, a servo motor drives a rotating shaft to rotate a robotic arm and an electric gripper. The electric gripper is rotated to a position above the product shell, and then automatically clamps and removes the product shell. The rotating shaft is then driven to reset the robotic arm and electric gripper to fit against the sidewall of the worktable, avoiding interference with the upper mold operation.

Description

Technical Field

[0001] This utility model relates to a molding die, and in particular to a molding die for the casing of 3C electronic products applied in the field of mold manufacturing technology. Background Technology

[0002] With the rapid development of technology, 3C electronic products such as mobile phones, tablets, and laptops are playing an increasingly important role in people's lives. Consumers are also raising their requirements for the appearance, performance, and quality of 3C electronic products. This poses a severe challenge to the manufacturing process of electronic product casings. Stamping dies are required to process 3C electronic products during the production process.

[0003] Chinese patent CN212822197U discloses a stamping die for 3C electronic products. This utility model uses a plug rod to pull out from the first and second sockets, and then the socket is pulled out from the slot. At this time, the movement of the socket drives the stamping head body to move until the stamping head body is separated from the mounting block, which achieves the advantage of convenient replacement. It solves the problem that existing 3C electronic stamping dies are inconvenient to replace during use, the stamping head is easily damaged after long-term use, and the replacement process is cumbersome, making them inconvenient for people to use.

[0004] After the stamping process is completed, 3C electronic products will be attached to the mold. In the high-frequency use of the existing demolding mechanism, the sliding contact surface between the ejector pin and the punch is prone to wear due to friction, resulting in uneven demolding force, or even jamming of the ejector pin, affecting the surface flatness of the product or demolding failure. Utility Model Content

[0005] The technical problem that this utility model aims to solve in view of the above-mentioned prior art is that in the high-frequency use of existing demolding mechanisms, the sliding contact surface between the ejector pin and the punch is prone to wear due to friction, resulting in uneven demolding force, or even jamming of the ejector pin, affecting the surface flatness of the product or demolding failure.

[0006] To address the aforementioned problems, this utility model provides a 3C electronic product casing molding mold, including a worktable. A hydraulic cylinder is fixedly connected to the top of the worktable, and the output end of the hydraulic cylinder is connected to an upper mold via a coupling. A support plate is installed on the worktable directly below the upper mold, and a lower mold is fixedly connected to the top of the support plate. An electric push rod is embedded in the worktable directly below the lower mold, and a pressure plate is connected to the movable end of the electric push rod. A protective sleeve is fitted on the surface of the pressure plate. Multiple grooves are equidistantly spaced in a ring on the inner wall of the support plate. Rollers corresponding to the grooves are fixedly connected to the side wall of the protective sleeve, and the rollers are locked and movably connected to the grooves. An inner groove is fixedly opened on the side of the worktable near the support plate, and a rotating shaft is rotatably connected to the inner wall of the inner groove. A collar is fitted on the surface of the rotating shaft, and a robotic arm is fixedly connected to the side wall of the collar. An electric gripper is connected to the movable end of the robotic arm. A servo motor is embedded in the bottom of the inner groove, and the output end of the servo motor is connected to the rotating shaft.

[0007] In the above-mentioned molding die, a protective sleeve is attached to the surface of the pressure plate with glue. The side wall of the protective sleeve is slidably connected to the inner wall of the lower die through a roller. This reduces the friction between the protective sleeve and the inner wall of the lower die, thereby preventing the electric push rod from getting stuck due to severe wear of the pressure plate.

[0008] As a further improvement of this application, a groove is provided on the worktable directly below the upper mold, a telescopic rod is fixedly connected in the groove, and the movable end of the telescopic rod is connected to the lower mold, and a compression spring is sleeved on the surface of the telescopic rod.

[0009] As a further improvement of this application, a buffer pad is detachably connected to the top of the telescopic rod, a locking block is fixedly connected to the bottom of the buffer pad, and a locking groove is opened at the top of the telescopic rod, and the locking block engages with the locking groove.

[0010] As a further improvement of this application, multiple sets of corresponding round holes are provided on the top of the buffer pad and the support plate, and screws are connected to the internal threads of the round holes.

[0011] As another improvement of this application, the cushioning pad is made of elastic and compressible rubber material.

[0012] As a further improvement to this application, a controller for controlling hydraulic cylinders, robotic arms, electric grippers, and servo motors is fixedly connected to the worktable.

[0013] In summary, the electronic component is placed on the pressure plate inside the tray. Then, the controller activates the hydraulic cylinder to drive the upper mold to stamp the electronic component. After stamping, the electric push rod is activated to push the pressure plate upward. The surface of the pressure plate is covered with a removable protective sleeve. As the pressure plate moves upward, the rollers on the side wall of the protective sleeve roll upward in the slide groove to reduce friction with the inner wall of the lower mold. When the pressure plate pushes the formed product shell outside the lower mold, the servo motor can be activated to drive the rotating shaft to rotate the robotic arm and electric gripper. The electric gripper is rotated to the position above the product shell, and then the electric gripper is activated to automatically clamp and remove the product shell. At this time, the rotating shaft is driven to reset the robotic arm and electric gripper to fit against the side wall of the worktable to avoid affecting the operation of the upper mold.

[0023] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0024] First implementation method:

[0025] Figures 1-5 This invention discloses a molding die for a 3C electronic product casing, comprising a worktable 1, a hydraulic cylinder 2 fixedly connected to the top of the worktable 1, an upper mold 3 connected to the output end of the hydraulic cylinder 2 via a coupling, a support plate 5 mounted on the worktable 1 directly below the upper mold 3, a lower mold 6 fixedly connected to the top of the support plate 5, an electric push rod 14 embedded on the worktable 1 directly below the lower mold 6, a pressure plate 7 connected to the movable end of the electric push rod 14, a protective sleeve 16 covering the surface of the pressure plate 7, and circumferentially spaced openings on the inner wall of the support plate 5. There are multiple slides 15. The protective sleeve 16 has rollers 17 corresponding to the slides 15 fixedly connected to its side wall. The rollers 17 are engaged and movablely connected to the slides 15. The worktable 1 has an inner groove fixedly opened on the side near the pallet 5. The inner wall of the inner groove is rotatably connected to a rotating shaft 13. A collar 12 is fitted on the surface of the rotating shaft 13. A robotic arm 8 is fixedly connected to the side wall of the collar 12. An electric gripper 9 is connected to the movable end of the robotic arm 8. A servo motor is embedded in the bottom of the inner groove, and the output end of the servo motor is connected to the rotating shaft 13.

[0026] A groove 20 is provided on the worktable 1 directly below the upper mold 3. A telescopic rod 18 is fixedly connected in the groove 20, and the movable end of the telescopic rod 18 is connected to the lower mold 6. A compression spring 19 is sleeved on the surface of the telescopic rod 18. A controller 10 for a control cylinder 2, a robotic arm 8, an electric gripper 9, and a servo motor is fixedly connected on the worktable 1.

[0027] The robotic arm 8 uses existing technology, and a suitable bidirectional robotic arm 8 from the existing technology is selected by a person skilled in the art for installation, such as EPSON T6-B602S.

[0028] The electric gripper 9 uses existing technology. Those skilled in the art can select a suitable dual electric gripper 9 from the existing technology for installation, such as SMC's MHS4 series.

[0029] Working principle: The electronic product component is placed on the pressure plate 7 inside the tray 5. Then, the controller 10 starts the hydraulic cylinder 2 to drive the upper mold 3 to stamp the electronic product component. After stamping, the electric push rod 14 is activated to push the pressure plate 7 upward. The surface of the pressure plate 7 is covered with a detachable protective sleeve 16. As the pressure plate 7 moves upward, the rollers 17 on the side wall of the protective sleeve 16 roll upward in the slide groove 15 to reduce friction with the inner wall of the lower mold 6. When the pressure plate 7 pushes the formed product shell to the outside of the lower mold 6, the servo motor can be activated to drive the rotating shaft 13 to drive the robotic arm 8 and the electric gripper 9 to rotate. The electric gripper 9 is rotated to the top of the product shell. Then, the electric gripper 9 is activated to automatically clamp and remove the product shell. At this time, the rotating shaft 13 is driven to reset the robotic arm 8 and the electric gripper 9 to fit against the side wall of the worktable 1 to avoid affecting the operation of the upper mold 3.

[0030] In this invention, a protective sleeve 16 is attached to the surface of the pressure plate 7 with glue. The side wall of the protective sleeve 16 is slidably connected to the groove 15 of the inner wall of the lower mold 6 via rollers 17. This reduces the friction between the protective sleeve 16 and the inner wall of the lower mold 6, thereby preventing the pressure plate 7 from being severely worn and causing the electric push rod 14 to jam.

[0031] Second implementation method:

[0032] Figure 1 and 6 - Figure 7 The telescopic rod 18 is shown to have a detachable buffer pad 4 at its top end. The bottom end of the buffer pad 4 is fixedly connected to a locking block 22. The top end of the telescopic rod 18 has a locking groove 21, and the locking block 22 engages with the locking groove 21. The top end of the buffer pad 4 and the support plate 5 both have multiple sets of corresponding round holes 23. The round holes 23 are internally threaded with screws 11. The buffer pad 4 is made of elastic and compressible rubber material.

[0033] Working principle: The tray 5 with the buffer pad 4 at the bottom is engaged with the slot 21 by the locking block 22. During the stamping process, the telescopic rod 18 and the compression spring 19, together with the elastic and compressible rubber buffer pad 4, can buffer the stamping mold and avoid the mold from breaking due to large impact force. The tray 5 is fixed to the buffer pad 4 by the screw 11 and the round hole 23. After loosening the screw 11, the tray 5 can be lifted vertically upward to separate the buffer pad 4, so that the buffer pad 4 and the tray 5 can be easily disassembled and assembled. The buffer pad 4 can be quickly replaced if it is damaged during long-term stamping.

[0034] This invention uses a buffer pad 4, a telescopic rod 18, and a compression spring 19 at the bottom of the support plate 5 to buffer the die during stamping and prevent it from breaking.

[0035] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
