Description

Technical Field

[0001] The invention relates to the technical field of mobile phone frame processing, and in particular to a stamping die for processing a high-strength mobile phone frame. Background Art

[0002] The production of mobile phone frames usually requires the cooperation of punching machines. Stamping dies are special process equipment used to process materials (metal or non-metal) into parts (or semi-finished products) during cold stamping. They are called cold stamping dies (commonly known as cold stamping dies). Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to separate or plastically deform it, thereby obtaining the required parts. Stamping dies are a process equipment used to process materials into workpieces or semi-finished products during stamping. They are the main process equipment for industrial production. When traditional mobile phone frames are stamped and formed, most of the materials are loaded manually. After stamping is completed, manual demoulding is required and the stamping residues on it need to be cleaned before stamping can be carried out. The whole process has low work efficiency and the stamping equipment has safety hazards, which does not provide good protection for the personal safety of the staff. Since there are many screw holes and camera holes on the mobile phone frame, it is difficult to stamp and demould with existing automated equipment. It cannot be demoulded quickly while protecting the mobile phone frame like manual operation, and there is no good collection mechanism for the residues after demoulding. Summary of the invention

The tops of the soft demoulding components and the hard demoulding components are both mounted on mounting frames. The tops of the mounting frames are movably connected with a plurality of roller groups 1, and the highest point of the roller group 1 is higher than the highest point of the mounting frame so that the roller group 1 contacts the demoulding module and the position of the roller group 1 closest to the demoulding module is lower than the positions of the other roller groups 1 for guiding. The difference between the soft demoulding component and the hard demoulding component is that the bottom of the mounting frame on the soft demoulding component is fixedly connected with an elastic component, while the bottom of the hard demoulding component is fixedly connected with a column, and the soft demoulding component and the hard demoulding component are fixedly connected with the outer side of the second synchronous belt through the elastic component and the column respectively; The stripping module comprises a stripping module body which is slidably connected to the lower mold. Both sides of the stripping module body are provided with arc chamfers to facilitate the introduction of soft stripping components and hard stripping components and to lift the overall position of the stripping module to eject the mobile phone frame.

[0006] Preferably: the stripping module includes a roller group 2 stripping module body arranged on both sides of the stripping module body, the roller group 2 stripping module body is specifically a plurality of rollers 3 and rolls and rubs with the upper mold through the plurality of rollers 3, and the highest point of the roller group 2 stripping module body is lower than the height of the stripping module body.

[0007] Preferably: the transmission assembly includes a gear bar fixed on the bottom of the upper mold and the gear bar is adapted to the number and position of the gears. The gear bar is meshed with the gears and when the gear bar moves downward, the rotation of the gear does not drive the second rotating shaft to rotate due to the one-way damping bearing. After the stamping is completed when the gear bar moves upward, it drives the gear and the second rotating shaft to rotate, and finally drives the synchronous belt 2 to move to utilize the soft demolding assembly and the hard demolding assembly to eject the demolding module to promote demolding.

[0013] Preferably, the middle portion of the second synchronous belt passes through the interior of the lower die and a support body is provided in the middle of the second synchronous belt just below the stamping groove for overall stamping stability.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. After the stamping is completed, when the upper mold drives the gear bar to move upward, the gear drives the rotating shaft 2 to rotate, and finally drives the synchronous belt 2 to rotate and move. When the synchronous belt 2 rotates and moves, the soft demolding component first uses the arc chamfer angle to enter the bottom of the demolding module as a whole to push the demolding module upward to perform the first step of demolding. Due to the stamping just now, the stamping force is large, and some places with smaller angles have greater stress and are not easy to be pushed at one time. If the pushing force is large, the frame of the mobile phone will be deformed. At this time, the telescopic rod and spring 2 at the bottom of the soft demolding component can be used for buffering when the resistance is large during the demolding process, and the soft demolding component can be used to release the mold. The first relatively slow force is applied, and then the synchronous belt 2 is continued to move until the hard demoulding component enters the bottom of the demoulding module. At this time, the bottom of the hard demoulding component is a column, and the column is used to perform the final demoulding work on the mobile phone frame. In addition, the number of circles driven by the gear to rotate during the upward movement of the gear bar can drive the synchronous belt 2 to move the distance of a demoulding group. During the entire demoulding process, the elastic demoulding is used to protect the mobile phone frame and loosen the pre-force for demoulding. Finally, the direct thrust is used for demoulding, which realizes the purpose of automatic demoulding under the premise of protecting the mold and has high efficiency, does not require manual intervention, and is convenient to operate; 2. Use the limiting metal spring on the inside of the collection hole to clamp the unnecessary waste during the stamping process, and then use the inclined groove to discharge it after continuous clamping and rising, so as to achieve the purpose of automatic waste cleaning. There are some screw holes and other heat dissipation holes on the frames of some mobile phones. These holes are small and not suitable for collection and cleaning by the collection hole method. You can use the negative pressure telescopic hose to directly suck the negative pressure, which achieves a targeted effect, is more reasonable and fully automated in operation, has higher efficiency and greater safety; 3. The setting of the demolding module body by the roller group 2 can reduce the friction between the demolding module body and the lower mold when the soft demolding component and the hard demolding component push the demolding module body, and convert the static friction into rolling friction, which makes it more convenient to demold the upper body of the demolding module body.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Embodiment 1: Figure 1-Figure 7As shown, the workpiece to be stamped is placed between the lower mold 1 and the upper mold 5, and then the upper mold 5 is pressed down by the external stamping equipment on the top of the upper mold 5 to perform the stamping work. During the descent of the upper mold 5, the upper mold 5 is engaged with the gear 13 to rotate. Since the gear 13 and the rotating shaft 11 are connected by a one-way damping bearing, the gear 13 will not drive the rotating shaft 11 to rotate during the descent of the gear bar 3. After the stamping is completed, when the upper mold 5 drives the gear bar 3 to move upward, the gear 13 drives the rotating shaft 11 to rotate, and finally drives the synchronous belt 2 16 to rotate and move. When the synchronous belt 2 16 rotates and moves, the soft demolding component 17 first uses the angle of the arc chamfer 703 to enter the overall bottom of the demolding module 7 to push the demolding module 7 upward to perform the first step of demolding. Since the stamping has just been performed, the stamping force is large, and some places with smaller angles have large stresses and are not easy to be pushed at one time. If If the pushing force is too strong, the frame of the mobile phone will be deformed. At this time, the telescopic rod 20 and the second spring 21 at the bottom of the soft demoulding component 17 can be used for buffering when the resistance is large during the demoulding process. The soft demoulding component 17 is used to perform the demoulding for the first time. After this time, the synchronous belt 16 is continued to move until the hard demoulding component 19 enters the bottom of the demoulding module 7 as a whole. At this time, the bottom of the hard demoulding component 19 is the column 18, and the column 18 is used to perform the final demoulding work on the frame of the mobile phone. In addition, the number of circles of the gear 13 driven to rotate during the upward movement of the gear bar 3 can drive the synchronous belt 16 to move the distance of a demoulding group. In the whole demoulding process, the elastic demoulding is used to protect the frame of the mobile phone, and the pre-force of demoulding is loosened. Finally, the demoulding is performed by direct thrust, which realizes the purpose of automatic demoulding under the premise of protecting the mold and has high efficiency, does not require manual intervention, and is convenient to operate. Embodiment 2: Figure 1 , 7 and Figure 8 As shown, when a larger camera hole appears on the mobile phone frame, a corresponding collection hole 402 is opened, and the limiting metal spring 403 inside the collection hole 402 is used to clamp the unnecessary waste during the stamping process, and then the inclined groove 401 is used to discharge the waste after continuous clamping and rising, so as to achieve the purpose of automatic waste cleaning. There are also some screw holes and other heat dissipation holes on some mobile phone frames. These holes are small and are not suitable for collection and cleaning by the collection hole 402. The negative pressure telescopic hose 22 can be used for direct negative pressure suction, so as to achieve a targeted effect, which is more reasonable and fully automated in operation, with higher efficiency and greater safety. Embodiment 3: Figure 3 , 4 and Figure 6As shown, the arrangement of the demolding module body 702 using the roller group 2 can reduce the friction between the demolding module body 702 and the lower mold 1 when the soft demolding component 17 and the hard demolding component 19 push the demolding module body 702, thereby converting static friction into rolling friction, making it easier to demold the upper body of the demolding module body 702.
