Description

Technical Field

[0001] The invention relates to the technical field of metal processing, and in particular to a device and a processing method for thickening a side wall of a notebook computer shell. Background Art

[0002] For a notebook computer case made of metal, in order to increase the supporting strength of the side panels of the case, the side panels of the case are thickened by stamping.

[0003] For example, the existing patent with application number CN201921223633.3, publication (announcement) number CN210498186U, and name “Metal Notebook Shell Extrusion Die” discloses “a lower die and an upper die, the lower die includes a floating lower support plate for supporting the inner side of the shell, a lower punch for flattening the shell facade, a floating inclined wedge block, and a side block that moves relative to the lower support plate under the drive of the inclined wedge block; the upper die includes an upper pressing block for pressing the shell plate surface and a side pressing block that can move relative to the upper pressing block, and the side pressing block moves relative to the upper pressing block under the drive of the side pressing block. The vertical surface after bending is thickened and shortened by extrusion, thereby realizing the processing of a notebook shell with a vertical surface thicker than the plate surface.”

[0004] During the actual processing, the applicant discovered that the metal notebook shell extrusion die provided by the above patent and the prior art have the same drawbacks: since the side panels of the shell need to be limited by side blocks such as those in the above patent during the thickening process to prevent the side panels from cracking or excessive thickness during the thickening process, and it is precisely because of the existence of the side blocks that the side panels of the shell will generate a large extrusion pressure with the side blocks and the lower support plate after being thickened between the side blocks and the lower support plate, resulting in the side panels of the shell being firmly pressed by the side blocks and the lower support plate after being thickened. The shell is tightly squeezed, which makes it difficult to remove the shell. For example, in the above-mentioned patent, although the side panels of the shell can be stably thickened by limiting the position of the side panels of the shell, after the thickening, the thickness of the shell side panels increases and a strong squeezing force is generated between the side panels and the lower support plate. It is difficult to move the floating inclined wedge upwards by relying on the elastic force of the floating inclined wedge, and it is difficult to separate the side panels from the shell, let alone loosen the shell side panels and the lower support plate, which makes it difficult to remove the shell. Obviously, limiting the position of the shell side panels and easily removing the shell are a pair of contradictory problems. It can be seen from this that how to limit the side panels of the shell to obtain stable thickening when the shell side panels are being thickened, and how to prevent the side panels of the shell from being clamped by the side panels and the lower support plate after the thickening is completed, and how to loosen the shell side panels and the lower support plate so as to facilitate the removal of the shell are technical problems that need to be solved urgently. Summary of the invention

[0005] The purpose of the present invention is to provide a device and a processing method for thickening the side wall of a notebook computer shell, so as to solve the above-mentioned deficiencies in the prior art.

[0006] In order to achieve the above-mentioned object, the present invention provides the following technical solution: a device for thickening the side wall of a laptop computer housing, comprising an upper die seat and an upper die seat arranged up and down, wherein a driving mechanism is connected to the upper die seat, and further comprising:

[0007] A lower support plate is vertically elastically slidably arranged in the upper die seat and is used to place the shell;

[0008] Two pier blocks are symmetrically arranged and vertically slidably disposed in the upper die seat, the lower support plate is located between the two pier blocks, and the left side plate and the right side plate of the shell are in one-to-one contact with the two pier blocks;

[0009] Two push-pull plates are symmetrically arranged and elastically slidably arranged in the upper die seat, and the two push-pull plates are linked to the two pier blocks in a one-to-one correspondence through a linking piece;

[0010] Two side blocks are symmetrically arranged and horizontally slidably clamped under the upper die seat, the two side blocks are located outside the two pier blocks and overlapped with the two pier blocks in a one-to-one correspondence, and the two push-pull plates are located outside the two side blocks and vertically slidably clamped with the two side blocks in a one-to-one correspondence;

[0011] After the pier is completed, the driving mechanism drives the upper mold base to move upward, pulling up the two side blocks so that the two side blocks overlap with the two pier blocks one by one to drive the two pier blocks to move upward. The upward movement of the two pier blocks pushes the shell and the lower support plate to loosen, while driving the two push-pull plates to slide through the linkage to separate from the side plates of the shell.

[0012] The above-mentioned notebook computer shell side wall thickening device is fixed on the pier block, and the side support block is provided with a corresponding inner groove, which is inserted into the corresponding inner groove, and the side support block and the pier block are overlapped by the abutment between the bottom and the bottom of the inner groove.

[0013] In the above-mentioned device for thickening the side wall of the laptop computer shell, a group of tension springs are fixedly installed between the two push-pull plates and the inner wall of the upper mold base. Based on the elastic force of the tension springs, a gap is formed between the bottom of the pier block and the bottom of the inner cavity of the upper mold base in the initial state. During thickening, the driving mechanism drives the upper mold base to move downward, so that the upper mold base presses down the shell to push the two pier blocks to move downward to the limit state. The two pier blocks are in one-to-one contact with the two pier blocks through the two side blocks of the linkage to limit the left and right side plates of the shell.

[0014] The above-mentioned laptop computer shell side wall thickening device, when the shell is placed on the lower support plate, the bottom of the left and right side plates of the shell abut against the tops of the two blocks one by one and there is a space between the bottom surface of the shell top plate and the top surface of the lower support plate, in the process of the two blocks being pressed downward by the upper mold base, the bottom surface of the shell top plate is fitted with the top surface of the lower support plate so that the top plate of the shell is not suspended when the left and right side plates of the shell are thickened.

[0015] The above-mentioned notebook computer shell side wall thickening device, the connecting part includes a swing plate, the two ends of the swing plate are respectively provided with a lower abutment rod and an upper abutment rod, the swing plate is also provided with a rotating shaft located between the lower abutment rod and the upper abutment rod and rotatably connected to the upper mold base, the pier block is provided with a horizontal sliding hole for the lower abutment rod to slide and insert, the push-pull plate is provided with an inner sliding groove for the upper abutment rod to slide and insert, when the pier block moves, the swing plate is driven to rotate by the lower abutment rod, and the swing plate then drives the push-pull plate to slide through the upper abutment rod.

[0016] The above-mentioned notebook computer shell side wall thickening device, two support plates corresponding to the two push-pull plates are fixed in the upper mold base, the top of the support plate is slidably abutted with the bottom of the push-pull plate, and a locking rod slidably plugged with the push-pull plate is fixedly installed on the side block through a fixed plate, and a locking hole for inserting the locking rod is opened on the support plate. When the side block abuts against the pier block, the locking rod and the locking hole are coaxial, and as the locking rod continues to move downward, the locking rod is inserted into the corresponding locking hole to lock the side block.

[0017] In the above-mentioned notebook computer housing side wall thickening device, the side of the side support block is fixedly provided with two guide rails arranged front and back oppositely, and the side of the push-pull plate is fixedly provided with two T-shaped sliding plates which are slidably plugged with the two guide rails in a one-to-one correspondence.

[0018] The above-mentioned laptop computer shell side wall thickening device has two receiving grooves corresponding to the two guide rails and penetrating the bottom of the side support block in the side support block, the receiving grooves are filled with oil-absorbing cotton, and a blocking block is inserted into the bottom of the receiving groove. The receiving groove is connected to the guide rail through a penetration hole opened on the side support block.

[0019] In the above-mentioned laptop computer shell side wall thickening device, a push rod corresponding to the blocking block is fixedly arranged in the upper mold base. During the downward movement of the side block, the push rod squeezes the corresponding blocking block to compress the oil-absorbing cotton so that the oil is smeared between the T-shaped slide plate and the guide rail through the penetration hole.

[0020] A method for processing the thickening of the side wall of a notebook computer housing is based on the above-mentioned device for thickening the side wall of a notebook computer housing, and comprises the following steps:

[0021] S1: Unloading: Place the shell on the lower support plate so that the left and right plates of the side abutment blocks abut against the tops of the two pier blocks one by one;

[0022] S2: Limiting the side plates of the shell: The driving mechanism drives the upper die seat to move downward. During the downward movement of the upper die seat, the shell is squeezed and the two pier blocks are driven to move downward to the limit state through the shell. During the downward movement of the two pier blocks to the limit state, the corresponding two push-pull plates are pushed to slide elastically through the linkage, thereby driving the two side abutment blocks to abut against the two pier blocks one by one to limit the left and right side plates of the shell;

[0023] S3: Locking the side abutment block: When the side abutment block abuts against the pier block, the locking rod fixedly connected to the side abutment block is coaxial with the locking hole on the support plate, and as the locking rod continues to move downward, the locking rod is inserted into the corresponding locking hole to lock the side abutment block;

[0024] S4: Thickening: When the locking rod is inserted into the corresponding locking hole, the upper die seat continuously presses down the shell, the side abutment block and the lower support plate, and the left and right plates of the shell are thickened with the cooperation of the two abutment blocks;

[0025] S5: Removing materials: After the left and right plates of the shell are thickened, they are firmly squeezed between the side abutment blocks and the lower support plate. In the process of driving the upper die seat upward, the two side abutment blocks are pulled upward so that the two side abutment blocks overlap with the two abutment blocks one by one to drive the two abutment blocks to move upward. The upward movement of the two abutment blocks pushes the shell and the lower support plate to loosen, and at the same time, the two push-pull plates are driven to slide through the linkage to separate from the side plates of the shell, and finally the shell is removed;

[0026] In step S1, when the bottom of the left and right side plates of the shell are in one-to-one contact with the tops of the two pier blocks and there is space between the bottom surface of the shell top plate and the top surface of the lower support plate, in step S, the two pier blocks are pressed downward by the upper mold base, so that in the process of the pier blocks moving downward, the bottom surface of the shell top plate is fitted with the top surface of the lower support plate so that the top plate of the shell is not suspended when the left and right side plates of the shell are thickened.

[0027] Beneficial effects:

[0028] 1. In the above technical scheme, the present invention provides a device and a processing method for thickening the side wall of a laptop computer shell. By setting the pier blocks in a movable form, the two side blocks and the two pier blocks are overlapped one by one during the upward movement of the upper mold base, and under the drive of the driving mechanism, the two pier blocks are pulled upward by the pulling force of the driving mechanism. The pulling force of the driving mechanism is sufficient to overcome the extrusion force on the shell so that the two pier blocks push the shell upward to loosen the shell and the lower support plate, and drive the two push-pull plates to slide in the opposite direction away from the shell through the connecting piece, so that the two push-pull plates are separated from the left and right side plates of the shell, so that the side plates of the shell are not squeezed by the push-pull plates and can also be loosened with the lower support plate, killing two birds with one stone. It can be seen that the present invention can limit the side plate of the shell when it is thickened to obtain a stable thickness, and can also prevent the side plate of the shell from being clamped by the side plate and the lower support plate after the thickening is completed, and can make the side plate of the shell loose between the lower support plate, thereby overcoming this contradiction, making it easy to remove the shell, and effectively solving the shortcomings of the prior art.

[0029] 2. In the present invention, since the pier block is in an active state, the gap between the pier block and the upper die seat is utilized so that in the process of the pier block being pressed down by the shell, not only can the push-pull plate be driven to slide elastically toward the shell through the linkage, so that the side blocks abut against the pier block to achieve one-to-one limitation of the left and right side plates of the shell by the two side blocks; and the gap between the pier block and the upper die seat can be utilized so that when the top plate of the shell is suspended when the shell is placed, before the side plates of the shell are pierced, the top plate of the shell can be fitted with the top surface of the lower support plate so that the top plate of the shell is not suspended. Therefore, when piercing, the side plate of the shell located between the top plate of the shell and the top of the lower support plate will not bulge inward or even break. It can be seen that the gap between the pier block and the upper die seat plays two unrelated roles and produces unexpected technical effects.

[0030] 3. Furthermore, when the upper die seat moves downward, after the side block contacts the pier block, the locking rod can be driven to insert into the corresponding locking hole to lock the side block. When the side plates of the shell are thickened, the two side blocks can limit the left and right side plates of the shell more stably. Moreover, the locking of the side blocks is automatically realized during the downward movement of the upper die seat, eliminating the operation of locking the side blocks separately, which can effectively improve the efficiency of the shell thickening.

[0031] 4. At the same time, in the process of the upper die seat moving downward, the present invention also realizes the effect of applying oil between the T-shaped slide plate and the guide rail to reduce the sliding friction between the T-shaped slide plate and the guide rail, eliminating the operation of applying oil separately.

[0044] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0045] First embodiment:

[0046] like Figure 1-9 As shown, a laptop computer housing side wall thickening device provided by an embodiment of the present invention comprises an upper die base 11 and an upper die base 12 arranged up and down, a driving mechanism is connected to the upper die base 11, and further comprises:

[0047] A lower support plate 1, which is vertically elastically slidably arranged in the upper die seat 12, and is used to place the housing 13;

[0048] Two pier blocks 2 are symmetrically arranged and vertically slidably disposed in the upper die seat 12, the lower support plate 1 is located between the two pier blocks 2, and the left and right plates of the housing 13 are in one-to-one contact with the two pier blocks 2;

[0049] Two push-pull plates 4 are symmetrically arranged and elastically slidably arranged in the upper die seat 12, and the two push-pull plates 4 are linked with the two pier blocks 2 in a one-to-one correspondence through a linking piece;

[0050] Two side abutments 3 are symmetrically arranged and horizontally slidably engaged with the lower portion of the upper die seat 11. The two side abutments 3 are located outside the two pier blocks 2 and overlapped with the two pier blocks 2 in a one-to-one correspondence. Two push-pull plates 4 are located outside the two side abutments 3 and vertically slidably engaged with the two side abutments 3 in a one-to-one correspondence.

[0051] After the thickening is completed, the driving mechanism drives the upper mold base 11 to move upward, pulling up the two side blocks 3 so that the two side blocks 3 overlap with the two pier blocks 2 one by one to drive the two pier blocks 2 to move upward. The upward movement of the two pier blocks 2 pushes the shell 13 and the lower support plate 1 to loosen, while driving the two push-pull plates 4 to slide through the linkage to separate from the side plates of the shell 13.

[0052] The laptop computer shell side wall thickening device provided in this embodiment is used to thicken the left and right side panels of the laptop computer shell to increase the strength of the side panels. The words related to directions and positions involved in the present invention are relative to the accompanying drawings. When the left and right side panels of the shell 13 are thickened, the shell 13 forms an integrally formed top panel and two side panels. Specifically, the driving mechanism is fixedly installed on the fixed frame, the driving mechanism is a servo hydraulic cylinder, the power output shaft of the driving mechanism is fixedly connected to the center of the upper die seat 11, the upper die seat 12 is located below the upper die seat 11, and the top of the upper die seat 12 is opened. A group of compression springs 9 is fixedly installed in the upper die seat 12, and the number of a group of compression springs 9 is multiple. The top of a group of compression springs 9 is fixedly connected to the bottom of the lower support plate 1, and the elastic sliding of the lower support plate 1 is achieved by the elasticity of the compression springs 9. The shell 13 is placed on the lower support plate 1, and the two pier blocks 2 are used to support the left and right side plates of the shell 13. The two pier blocks 2 are slidably set in the upper mold base 12. The front and rear side plates of the pier blocks 2 are integrally provided with a vertical slide plate 201. The inner wall of the upper mold base 12 is provided with a vertical slide groove corresponding to the vertical slide plate 201 (not shown in the figure). The vertical slide plate 201 is slidably set in the vertical slide groove, and the opposite surfaces of the two pier blocks 2 are in sliding contact with the left and right side surfaces of the lower support plate 1 in a one-to-one corresponding manner.

[0053] Two push-pull plates 4 are elastically slidably arranged in the upper mold base 12 in the horizontal direction, wherein the front and rear sides of the push-pull plates 4 are integrally provided with horizontal slide plates 401, and the inner wall of the upper mold base 12 is provided with horizontal slide grooves (not shown in the figure) corresponding to the horizontal slide plates 401, and the horizontal slide plates 401 are slidably arranged in the horizontal slide grooves, and the two push-pull plates 4 are located on the outside of the two side abutment blocks 3 and are vertically slidably engaged with the two side abutment blocks 3 in a one-to-one manner, so that the push-pull plates 4 and the side abutment blocks 3 can slide relative to each other in the vertical direction and can be linked in the horizontal direction, so that the push-pull plates 4 and the side abutment blocks 3 can slide synchronously in the horizontal direction and can slide relative to each other in the vertical direction. Among them, the two push-pull plates 4 are linked to the two pier blocks 2 through a linkage, and when the pier blocks 2 move vertically, the corresponding push-pull plates 4 can be driven to slide in the horizontal direction through the linkage, and the horizontal sliding of the push-pull plates 4 drives the side abutment blocks 3 to slide horizontally. The top fixed array of the side support block 3 has multiple T-shaped sliders 301, and the bottom of the upper mold base 11 is provided with T-shaped slots 1101 corresponding to the T-shaped sliders 301. The T-shaped sliders 301 are horizontally slidably arranged in the corresponding T-shaped slots 1101. The T-shaped sliders 301 and the T-shaped slots 1101 will not be separated in the vertical direction, so that when the upper mold base 11 moves up and down, the two side support blocks 3 can be driven to move up and down synchronously. At the same time, the side support blocks 3 can be pushed and pulled horizontally by the push-pull plate 4 while moving up and down.

[0054] At the same time, the two side blocks 3 are located on the outside of the two pier blocks 2 and overlap with the two pier blocks 2 one by one. When the upper mold base 11 moves downward, the side blocks 3 do not overlap with the pier blocks 2. When the upper mold base 11 moves upward, it drives the side blocks 3 to move synchronously, so that the side blocks 3 gradually overlap with the pier blocks 2. After the side blocks 3 overlap with the pier blocks 2, the side blocks 3 continue to be driven upward by the upper mold base 11, which will pull the pier blocks 2 to move upward synchronously.

[0055] Its working principle is: first, place the shell 13 on the lower support plate 1, so that the left and right plates of the side stop blocks 3 are in one-to-one contact with the tops of the two pier blocks 2, and the driving mechanism drives the upper die seat 11 to move downward. During the downward movement of the upper die seat 11, the shell 13 is squeezed and the two pier blocks 2 are driven to move downward to the limit state through the shell 13. During the downward movement of the two pier blocks 2 to the limit state, the corresponding two push-pull plates 4 are pushed elastically to slide through the linkage, thereby driving the two side stop blocks 3 to correspond to the two pier blocks 2 to limit the left and right side plates of the shell 13, and then the upper die seat 11 continues to move downward, and the upper die seat 11 squeezes the shell 13, the side stop blocks 3 and the lower support plate 1 to move downward, and the left and right plates of the shell 13 are thickened with the cooperation of the two pier blocks 2. After the left and right plates of the shell 13 are thickened, they are firmly squeezed between the side support blocks 3 and the lower support plate 1, and then the driving mechanism drives the upper mold base 11 to move upward. In the process of driving the upper mold base 11 to move upward, the two side support blocks 3 are pulled up to make the two side support blocks 3 overlap with the two pier blocks 2 one by one. After overlapping, the two side support blocks 3 drive the two pier blocks 2 to move up synchronously. The upward movement of the two pier blocks 2 promotes the looseness between the shell 13 and the lower support plate 1, and at the same time drives the two push-pull plates 4 to slide in the opposite direction away from the shell 13 through the linkage, so that the two push-pull plates 4 are separated from the left and right side plates of the shell 13. Since the side plates of the shell 13 are not squeezed by the push-pull plates 4 and are loosened from the lower support plate 1, the shell 13 can be easily removed.

[0056] It can be seen that the present invention sets the pier block 2 in a movable form so that the two side blocks 3 and the two pier blocks 2 are overlapped one by one during the upward movement of the upper mold base 11, and under the drive of the driving mechanism, the two pier blocks 2 are pulled upward by the pulling force of the driving mechanism. The pulling force of the driving mechanism is sufficient to overcome the extrusion force exerted on the shell 13 so that the two pier blocks 2 push the shell 13 upward to loosen the shell 13 and the lower support plate 1, and drive the two push-pull plates 4 to slide in the opposite direction away from the shell 13 through the connecting parts, so that the two push-pull plates 4 are separated from the left and right side plates of the shell 13, so that the side plates of the shell 13 are not squeezed by the push-pull plates 4 and are loosened from the lower support plate 1, thereby killing two birds with one stone. It can be seen that the present invention can limit the side plates of the shell by the side blocks when the thickness is being piled to obtain a stable thickness, and can also not be clamped by the side blocks and the lower support plate after the shell side plates are completed, and can make the shell side plates and the lower support plate loose, thereby overcoming this contradiction, making it easy to remove the shell, and effectively solving the shortcomings of the prior art.

[0057] Moreover, the side plates of the shell 13 are not squeezed by the push-pull plate 4, and the looseness between the side plates of the side abutment blocks 3 and the lower support plate 1 is automatically achieved during the upward movement of the upper die base 11, which greatly improves the working speed.

[0058] In this embodiment, 203 is fixed on the pier block 2, and an inner groove 305 corresponding to 203 is opened on the side support block 3. 203 is inserted into the corresponding inner groove 305, and the overlap of the side support block 3 and the pier block 2 is achieved by the abutment between the bottom of 203 and the bottom of the inner groove 305.

[0059] Among them, a group of tension springs 8 are fixedly installed between the two push-pull plates 4 and the inner wall of the upper mold base 12. There are multiple tension springs 8 in each group of tension springs 8. Based on the elastic force of the tension springs 8, a gap is formed between the bottom of the pier block 2 and the bottom of the inner cavity of the upper mold base 12 in the initial state. When the pier is thickened, the driving mechanism drives the upper mold base 11 to move downward, so that the upper mold base 11 presses down the shell 13 to push the two pier blocks 2 to move down to the limit state. The two pier blocks 2 are in one-to-one contact with the two pier blocks 2 through the two side blocks 3 of the linkage to limit the left and right side plates of the shell 13. Specifically, since the push-pull plate 4 is linked to the pier block 2 through a linkage, the setting of the linkage allows the push-pull plate 4 to be stopped at a specific position under the elastic force of the tension spring 8. After the position of the push-pull plate 4 is determined, the height of the pier block 2 is specified through the linkage, so that the bottom height of the pier block 2 is constant in the initial state. At this time, a gap is formed between the bottom of the pier block 2 and the bottom of the inner cavity of the upper mold base 12. Based on the existence of the gap, when the upper mold base 11 moves downward, it can squeeze the shell 13 to drive the two pier blocks 2 to move downward. In the process of the pier block 2 moving downward, the push-pull plate 4 is driven by the linkage to slide elastically toward the shell 13. When the bottom of the pier block 2 moves down to the limit state, the bottom of the pier block 2 abuts against the bottom of the inner cavity of the upper mold base 12, and the side block 3 abuts against the pier block 2. At this time, the two side blocks 3 realize the one-to-one limitation of the left and right side plates of the shell 13. It can be seen that the present invention cleverly utilizes the movable setting of the two pier blocks 2 and the gap between the bottom of the pier block 2 and the bottom of the inner cavity of the upper mold base 12, so that the two side blocks 3 can limit the left and right side plates of the shell 13 during the downward movement of the two pier blocks 2, which can further improve the operation speed.

[0060] Furthermore, since the left and right side panels of the shell 13 need to be bent first when the left and right side panels are thickened, and the lengths of the left and right side panels of the shell 13 are different after the bending is completed, and since the height difference between the top of the pier block 2 and the top of the lower support plate 1 is certain, when the left and right side panels of the shell 13 are longer, when the shell 13 is placed on the lower support plate 1 and abuts against the tops of the two pier blocks 2, there will be space between the bottom surface of the top panel of the shell 13 and the top surface of the lower support plate 1 and they cannot fit together. At this time, the top panel of the shell 13 is suspended (such as Figure 6As shown in the figure, if the side panels of the shell 13 are directly thickened, the side panels of the shell 13 located between the top plate of the shell 13 and the top of the lower support plate 1 will bulge inward or even break. For this reason, in the present invention, when the shell 13 is placed on the lower support plate 1, the bottoms of the left and right side panels of the shell 13 are in one-to-one contact with the tops of the two piers 2, and there is space between the bottom surface of the top plate of the shell 13 and the top surface of the lower support plate 1. Based on the gap between the bottom of the pier 2 and the bottom of the inner cavity of the upper mold base 12, when the upper mold base 11 moves downward, it first presses down the shell 13 to make the shell 13 and the two piers 2 move downward synchronously. When the shell 13 moves downward, the lower support plate 1 does not move, so that the bottom surface of the top plate of the shell 13 The top surface of the lower support plate 1 is gradually fitted, and the bottom surface of the top plate of the shell 13 is fitted with the top surface of the lower support plate 1 before the pier block 2 moves down to the limit position. The side plates of the shell 13 will be thickened only after the pier block 2 moves down to the limit position. At this time, the top plate of the shell 13 is not suspended during the thickening, so the above-mentioned thickening of the side plates of the shell 13 will not cause the side plates of the shell 13 located between the top plate of the shell 13 and the top of the lower support plate 1 to bulge inward or even break. That is: in the process of the two pier blocks 2 being pressed down by the upper die seat 11, the bottom surface of the top plate of the shell 13 is fitted with the top surface of the lower support plate 1 so that the top plate of the shell 13 is not suspended when the left and right side plates of the shell 13 are thickened.

[0061] Thus, it can be seen that in the present invention, since the pier block 2 is in an active state, the gap between the pier block 2 and the upper mold base 12 is utilized, so that in the process of the pier block 2 being pressed down and moved by the shell 13, not only can the push-pull plate 4 be driven to slide elastically toward the shell 13 through the linkage, so that the side stop blocks 3 abut against the pier block 2 to achieve the one-to-one limitation of the left and right side plates of the shell 13 by the two side stop blocks 3; and the gap between the pier block 2 and the upper mold base 12 can be utilized to make the top plate of the shell 13 fit with the top surface of the lower support plate 1 before the side plates of the shell 13 are thickened when the shell 13 is placed, so that the top plate of the shell 13 is not suspended in the air. Therefore, when the pier is pressed, the side plate of the shell 13 located between the top plate of the shell 13 and the top of the lower support plate 1 will not bulge inward or even break, thereby producing an unexpected technical effect.

[0062] If the problem of the top plate of the shell 13 being suspended in the air when the side plate of the shell 13 is thickened is solved by increasing the height difference between the top of the lower support plate 1 and the top of the pier block 2, the downward movement distance of the lower support plate 1 will be increased, thereby increasing the compression degree of the compression spring 9, and further increasing the resistance of the upper mold base 11 to the downward movement. Therefore, it is not recommended to solve the above technical problem by increasing the height difference between the top of the lower support plate 1 and the top of the pier block 2.

[0063] In this embodiment, the connecting part includes a swing plate 7, and the two ends of the swing plate 7 are respectively provided with a lower abutment rod 702 and an upper abutment rod 703. The swing plate 7 is also provided with a rotating shaft 701 located between the lower abutment rod 702 and the upper abutment rod 703 and rotatably connected to the upper mold base 12. The pier block 2 is provided with a horizontal sliding hole 202 for the lower abutment rod 702 to slide and insert, and the push-pull plate 4 is provided with an inner sliding groove 402 for the upper abutment rod 703 to slide and insert. When the pier block 2 moves, the swing plate 7 is driven to rotate by the lower abutment rod 702, and the swing plate 7 then drives the push-pull plate 4 to slide through the upper abutment rod 703. Specifically, the horizontal length of the horizontal sliding hole 202 is greater than the diameter of the lower abutting rod 702, and the vertical length of the horizontal sliding hole 202 is equal to the diameter of the lower abutting rod 702, so that the lower abutting rod 702 can move horizontally in the horizontal sliding hole 202, the vertical length of the inner sliding groove 402 is greater than the diameter of the upper abutting rod 703, and the horizontal length of the inner sliding groove 402 is equal to the diameter of the lower abutting rod 702, so that the upper abutting rod 703 can move vertically in the inner sliding groove 402, so when the pier block 2 moves up and down, the swing plate 7 can be driven to rotate around the rotating shaft 701 through the lower abutting rod 702, and when the swing plate 7 rotates, the push-pull plate 4 is driven to slide elastically in the horizontal direction through the upper abutting rod 703, and when the push-pull plate 4 slides horizontally, it drives the side abutment block 3 to slide synchronously. The side of the push-pull plate 4 is also provided with an avoidance opening 403 corresponding to the inner sliding groove 402, and the inner sliding groove 402 is located in the avoidance opening 403, and the avoidance opening 403 is used to avoid the swing plate 7.

[0064] Among them, two support plates 14 corresponding to the two push-pull plates 4 are fixed in the upper mold base 12, and two rotating shafts 701 are rotatably set on the two support plates 14 in a one-to-one manner. The top of the support plate 14 is slidably abutted with the bottom of the push-pull plate 4, so that the support plate 14 generates a supporting force on the push-pull plate 4. A locking rod 6 slidably plugged with the push-pull plate 4 is fixedly installed on the side stop block 3 through the fixing plate 5. A through hole 405 adapted to the locking rod 6 is provided on 4 for the sliding insertion of the locking rod 6. A locking hole (not shown in the figure) for the locking rod 6 to be inserted is provided on the support plate 14. When the side stop block 3 is abutted with the pier block 2, the locking rod 6 is coaxial with the locking hole. As the locking rod 6 continues to move downward, the locking rod 6 is inserted into the corresponding locking hole to lock the side stop block 3. Specifically, during the downward movement of the upper mold base 11, after the side support block 3 abuts against the pier block 2, the locking rod 6 can be driven to be inserted into the corresponding locking hole to lock the side support block 3. When the side panels of the shell 13 are thickened, the two side support blocks 3 can limit the left and right side panels of the shell 13 more stably, and the locking of the side support blocks 3 is automatically achieved during the downward movement of the upper mold base 11, eliminating the operation of individually locking the side support blocks 3, which can effectively improve the efficiency of thickening the shell.

[0065] Similarly, when the driving mechanism drives the upper mold base 11 to move upward, the upper mold base 11 drives the two side blocks 3 to move upward, and the two side blocks 3 drive the corresponding locking rods 6 to slide upward to disengage the locking rods 6 from the locking holes, thereby unlocking the side blocks 3 and the push-pull plates 4.

[0066] In this embodiment, two guide rails 302 arranged opposite to each other front and back are fixedly provided on the side of the side support block 3, and two T-shaped slide plates 404 are fixedly provided on the side of the push-pull plate 4, which are slidably plugged into the two guide rails 302 in a one-to-one correspondence. The sliding plug-in between the guide rails 302 and the T-shaped slide plates 404 enables the side support block 3 and the push-pull plate 4 to slide against each other in the vertical direction and to slide synchronously in the horizontal direction.

[0067] Among them, two receiving grooves corresponding to the two guide rails 302 and running through the bottom of the side support block 3 are opened in the side support block 3, and the receiving grooves are filled with oil-absorbing cotton (not shown in the figure), and the oil-absorbing cotton absorbs oil to reduce the friction between the guide rail 302 and the T-shaped slide plate 404. A blocking block 304 is inserted at the bottom of the receiving groove, and the blocking block 304 is used to block the bottom of the receiving groove. The receiving groove is connected with the guide rail 302 through a penetration hole 303 opened on the side support block 3.

[0068] Furthermore, a return spring (not shown in the figure) is embedded inside the oil-absorbing cotton. The blocking block 304 is squeezed and slid in the receiving groove. The return spring pushes the blocking block 304 to slide and reset. A push rod 10 corresponding to the blocking block 304 is fixedly arranged in the upper mold base 12. During the downward movement of the side block 3, the push rod 10 squeezes the corresponding blocking block 304 to compress the oil-absorbing cotton so that the oil passes through the penetration hole 303 and is smeared between the T-shaped slide 404 and the guide rail 302. When the side block 3 moves upward, the elastic force of the return spring is released to push the blocking block 304 to reset. It can be seen that in the process of the upper mold base 11 moving downward, the present invention realizes the effect of smearing the oil between the T-shaped slide 404 and the guide rail 302 to reduce the sliding friction between the T-shaped slide 404 and the guide rail 302, eliminating the operation of applying the oil separately.

[0069] Second embodiment:

[0070] like Figure 1-9 As shown, a method for processing the thickening of the side wall of a notebook computer housing comprises the following steps:

[0071] S1: Unloading: placing the shell 13 on the lower support plate 1, so that the left and right plates of the side abutment blocks 3 abut against the tops of the two pier blocks 2 one by one;

[0072] S2: Limiting the side plates of the shell 13: The driving mechanism drives the upper die seat 11 to move downward. During the downward movement of the upper die seat 11, the shell 13 is squeezed and the two pier blocks 2 are driven to move downward to the limit state through the shell 13. During the downward movement of the two pier blocks 2 to the limit state, the corresponding two push-pull plates 4 are pushed to slide elastically through the linkage, thereby driving the two side abutment blocks 3 to abut against the two pier blocks 2 one by one to limit the left and right side plates of the shell 13;

[0073] S3: Locking the side abutment block 3: When the side abutment block 3 abuts against the pier block 2, the locking rod 6 fixedly connected to the side abutment block 3 is coaxial with the locking hole on the support plate 14, and as the locking rod 6 continues to move downward, the locking rod 6 is inserted into the corresponding locking hole to lock the side abutment block 3;

[0074] S4: Thickening: When the locking rod 6 is inserted into the corresponding locking hole, the upper die seat 11 continuously presses down the shell 13, the side abutment block 3 and the lower support plate 1, and the left and right plates of the shell 13 are thickened with the cooperation of the two abutment blocks 2;

[0075] S5: Removing materials: After the left and right plates of the shell 13 are thickened, they are firmly squeezed between the side abutment blocks 3 and the lower support plate 1. In the process of driving the upper die base 11 upward, the two side abutment blocks 3 are pulled upward so that the two side abutment blocks 3 overlap with the two abutment blocks 2 one by one to drive the two abutment blocks 2 to move upward. The upward movement of the two abutment blocks 2 pushes the shell 13 and the lower support plate 1 to loosen, and at the same time drives the two push-pull plates 4 to slide through the linkage to separate from the side plates of the shell 13, and finally the shell 13 can be removed;

[0076] In step S1, when the bottom of the left and right side plates of the shell 13 abut against the tops of the two pier blocks 2 one by one and there is space between the bottom surface of the top plate of the shell 13 and the top surface of the lower support plate 1, in step S2, the two pier blocks 2 are pressed down and moved by the upper mold base 11, so that in the process of the pier blocks 2 moving downward, the bottom surface of the top plate of the shell 13 fits with the top surface of the lower support plate 1 so that the top plate of the shell 13 is not suspended when the left and right side plates of the shell 13 are thickened.

[0077] In step S4, two receiving grooves corresponding to the two guide rails 302 and penetrating the bottom of the side abutment block 3 are opened in the side abutment block 3, and the receiving grooves are filled with oil-absorbing cotton (not shown in the figure), and the oil-absorbing cotton absorbs oil to reduce the friction between the guide rail 302 and the T-shaped slide plate 404. A blocking block 304 is inserted into the bottom of the receiving groove, and the blocking block 304 is used to block the bottom of the receiving groove. The receiving groove is connected to the guide rail 302 through the penetration hole 303 opened on the side abutment block 3, and the oil-absorbing cotton is embedded inside. There is a return spring (not shown in the figure), and the blocking block 304 is squeezed and slid in the receiving groove. The return spring pushes the blocking block 304 to slide and reset. A push rod 10 corresponding to the blocking block 304 is fixedly set in the upper mold base 12. During the downward movement of the side block 3, the push rod 10 squeezes the corresponding blocking block 304 to compress the oil-absorbing cotton so that the oil passes through the penetration hole 303 and is smeared between the T-shaped slide 404 and the guide rail 302. When the side block 3 moves up, the elastic force of the return spring is released to push the blocking block 304 to reset. It can be seen that in the process of the upper mold base 11 moving downward, the present invention realizes the effect of smearing oil between the T-shaped slide 404 and the guide rail 302 to reduce the sliding friction between the T-shaped slide 404 and the guide rail 302, eliminating the operation of applying oil separately.

[0078] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
