Description

Technical Field

[0001] The utility model relates to the technical field of notebook shell molds, in particular to a die for repairing the step difference shaping of a notebook shell. Background Technique

[0002] With the rapid development of today's real society, notebook computers are becoming more and more popular and popular because of their small size and convenient carrying. However, during the process of carrying or working outside, it is inevitable that the shell will be bumped and deformed. Generally, we will choose to reassemble a new shell or use a hammer to knock and shape it for repair.

[0003] The existing notebook shell repair method usually selects the die forging forming technology. The notebook shell that needs step difference shaping is placed in the die, and a hydraulic press is used to overlap and stamp the upper and lower dies, and the deformed part is repaired and integrated back to its original state, improving the material utilization rate and avoiding unnecessary resource waste.

[0004] At present, although the die stamping of the notebook shell can achieve step difference shaping and repair, there are still the following problems: 1. Since the hydraulic press cannot move up and down too fast, otherwise the shell may be damaged due to excessive force, so the moving process is slow and the repair efficiency of the shell is low; 2. After the die stamping is completed, the stamped parts usually adhere to the die body, and it is difficult to take the parts manually. For this reason, we have proposed a die for repairing the step difference shaping of a notebook shell. Content of the Utility Model

[0005] The purpose of the utility model is to provide a die for repairing the step difference shaping of a notebook shell, including a lower die assembly for placing the notebook shell. The lower die assembly includes a lower template arranged directly below the notebook shell and a bottom plate assembly fixedly connected below the lower template. A boss hole penetrates through the center of the lower template, and limiting bosses are integrally formed at the four corners of the lower template. A sliding groove is formed on the back surface of the lower template. A boss is movably connected in the boss hole. The bottom plate assembly includes a bottom plate threadedly connected below the lower template, a sensor bracket threadedly connected to the upper end surface of the bottom plate, and a sensor tightly connected to the side wall of the sensor bracket.

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figure 1 - Figure 4, The figure shows a die for repairing the step difference of a notebook shell according to the present utility model, which includes a lower die assembly 5 for placing the notebook shell. The lower die assembly 5 includes a lower template 510 disposed directly below the notebook shell and a bottom plate assembly 540 fixedly connected below the lower template 510. A boss hole 511 penetrates through the center of the lower template 510. Limiting bosses 512 are integrally formed at the four corners of the lower template 510. A sliding groove 514 is formed on the back surface of the lower template 510. A boss 530 is movably connected in the boss hole 511. The bottom plate assembly 540 includes a bottom plate 541 threadedly connected below the lower template 510, a sensor bracket 545 threadedly connected to the upper end surface of the bottom plate 541, and a sensor 546 tightly connected to the side wall of the sensor bracket 545. A plurality of guide holes 542 and threaded holes 543 are formed on the upper end surface of the bottom plate 541. A push rod groove 548 is formed on the upper end surface of the bottom plate 541. A 574 is slidably connected in the push rod groove 548. An upper die assembly 4 is slidably connected directly above the lower die assembly 5. Guide columns 410 are tightly connected to the lower die assembly 5 through the guide holes 542. A connecting plate 430 is slidably connected to the guide columns 410. A connecting hole 431 and a plurality of first bolt holes 432 are formed on the connecting plate 430. An upper template 440 is tightly connected below the connecting plate 430. A second bolt hole 441 is formed on the upper template 440.

[0022] It can be understood that the sizes of the limiting bosses 512 and the upper template 440 are adapted to the notebook shell requiring step difference repair. When it is necessary to repair notebook shells of different models with step differences, only the upper template 440 and the lower template 510 need to be disassembled and replaced by threading.

[0023] At the same time, it should be noted that the guide columns 410 cooperate with the guide connection holes on the connecting plate 430, and an appropriate amount of lubricating grease can be applied to increase the smoothness of the mechanism and reduce the internal friction loss of the mechanism.

[0024] A hydraulic cylinder 2 is tightly connected to the upper end of the connecting hole 431. The top end of the hydraulic cylinder 2 is tightly connected to a top plate 1 by welding. Outer supports 3 are welded and tightly connected to both ends below the top plate 1. The ends of the outer supports 3 are welded and tightly connected to the bottom plate 541.

[0025] The connecting plate 430 and the upper template 440 are tightly connected by passing an upper bolt 450 through the first bolt hole 432 and the second bolt hole 441 and tightening the upper nut 420.

[0026] The lower template 510 and the bottom plate 541 are tightly connected by passing a lower screw 520 through the counterbore 513 and the threaded hole 543 and tightening. The sensor bracket 545 and the bottom plate 541 are tightly connected by passing a positioning screw 544 through the threaded hole.

[0027] It should be understood that the height sensed by the sensor 546 should be slightly higher than the plane of 510, so as to slightly advance the deceleration of the hydraulic cylinder 2 to carry out stable stamping.

[0028] The top end of the guide post 410 is provided with a head with a larger diameter dimension for limiting the up and down movement of the connecting plate 430, and the connecting hole 431 is tightly connected with the hydraulic cylinder 2 by threads.

[0029] The limiting boss 512 is provided with a rounded corner to avoid scratching the notebook shell. The size of the boss hole 511 is adapted to the size of the boss 530. The top end of the boss 530 is provided with a chamfer to make its up and down movement smoother and avoid jamming.

[0030] The front end of the push rod 547 is provided with a rounded corner to make the contact between the front end of the push rod 547 and the boss 530 smoother. A circular hole for stretching convenient for personnel operation is opened at the end. The size of the sliding groove 514 is adapted to the front end of the push rod 547. The push rod groove 548 is matched with the size of the push rod 547 to facilitate the stretching of the push rod 547 and improve the smoothness of the mechanism.

[0031] Working principle of the present utility model: When the present utility model is in use, first stretch the push rod 547 outwards to ensure that the boss 530 completely descends and check whether the surface of the lower template 510 is flat and smooth. Place the notebook shell that needs step difference shaping into the lower template 510. Turn on the switch to start the hydraulic cylinder 2. When the hydraulic cylinder 2 drives the upper die assembly 4 to quickly descend along the guide post 410 to be close to the lower template 510, upon receiving the signal feedback from the sensor 546, reduce the speed and carry out stamping and shaping slowly and stably. After the step difference shaping is completed, control the hydraulic cylinder 2 to lift up to the original position. Push the push rod 547 inwards along the push rod groove 548. The boss 530 is forced to protrude, and the notebook shell is pushed out of the lower template 510 to take out the finished product. The structure of the present utility model is simple, the cost is low, the efficiency and stability are both high, and the range of notebook shells that can be shaped can be expanded by replacing the upper template 440 and the lower template 510.

[0032] The above content further elaborates on the present utility model in combination with specific embodiments. It cannot be determined that the specific implementation of the present utility model is only limited to these descriptions. For those of ordinary skill in the technical field to which the present utility model belongs, without departing from the concept of the present utility model, several simple deductions or substitutions can still be made, and all should be regarded as belonging to the protection scope determined by the claims submitted for the present utility model.
