Description

Technical Field

[0001] The utility model relates to the field of mobile phone production equipment, in particular to a mobile phone shell correction mold. Background Art

[0002] The mobile phone shell is usually composed of four major parts: the front shell (upper front), the front support (upper back), the back support (lower front), the back shell (lower back) and some small parts, such as the battery cover, buttons, windows, buckles, anti-slip strips, etc. When we need to replace or repair the mobile phone shell, we use the pressing and correction device to bond the mobile phone shell. At this time, we need to use the clamping tool to clamp and fix the mobile phone shell, so that the staff can press and correct the mobile phone shell.

[0003] The utility model patent with Chinese patent application number CN202321665519.2 discloses a mobile phone shell pressing and correction fixture, including a workbench, the top front and rear sides of the workbench are fixedly connected with fixed blocks, the adjacent sides of the two fixed blocks on one side are fixedly connected with slide bars, the outer wall of the slide bar is slidably connected with two moving blocks, the top of one side of the two moving blocks is rotatably connected with connecting rods through the intermediate shaft, the middle side of the outer wall of the slide bar is provided with springs, one end of the two connecting rods is rotatably connected with connecting members through the shaft, and one side of the connecting member is fixedly connected with a clamping plate. In the utility model, by the coordinated setting of the workbench, fixed block, slide bar, moving block, connecting rod, spring, connecting member and clamping plate, the connecting rod drives the two moving blocks to move outward by pressing the clamping plate, and the mobile phone shell is clamped by the action of the spring, and the cooperation of the set slide bar and moving block is utilized. However, the device has only one clamping station, and the loading and unloading needs to be stopped, and the operation cannot be performed continuously without stopping, thereby affecting the processing efficiency of the mobile phone middle frame.

[0004] However, when the device is in use, the shape of the clamping plate is long and strip-shaped. During correction, the clamping plate cannot reshape the details of the mobile phone frame, which will affect the shaping effect of the mobile phone case. Utility Model Content

[0005] In view of the above problems, the utility model provides a mobile phone shell correction mold, which places the mobile phone shell in a placement bin, then moves the upper plate so that the interference part contacts the mobile phone shell, and the top of the moving rod assembly is deformed accordingly according to the outer shape of the mobile phone shell. Then, the moving rod assembly is pressed downward to shape the mobile phone shell, and then the limit assembly is driven to limit the upward movement of the moving rod assembly to maintain the pressure for pressing and shaping, thereby solving the technical problem that the details of the mobile phone shell cannot be shaped in the prior art.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A mobile phone shell correction mold, comprising:

[0008] A mold base, the mold base comprising a lower plate, a positioning block mounted on the lower plate, a placement bin opened on the positioning block, an upper plate located directly above the positioning block and movable up and down, and an adjustment mechanism for controlling the movement of the upper plate;

[0010] A distribution area of ​​several groups of the moving rod assemblies faces the placement bin. After the abutment portion contacts the mobile phone housing, the moving rod assembly moves according to the mobile phone housing and the deformation of the mobile phone housing. The deformation of the mobile phone housing can be corrected by pressing the moving rod assembly. The limiting assembly can enable the moving rod assembly to maintain pressing on the mobile phone housing.

[0011] As an improvement, the adjustment mechanism includes four groups of columns arranged on the lower plate, a sliding sleeve installed on the upper plate and correspondingly slidably sleeved on the column, a spring a correspondingly sleeved on the column and located between the sliding sleeve and the lower plate, a threaded hole correspondingly opened on the side of the sliding sleeve, and a top screw threadedly arranged in the threaded hole.

[0013] As an improvement, the moving rod assembly includes a square hole opened on the upper plate, a square rod slidably arranged on the square hole, a pressing plate arranged on the square rod, and a spring b sleeved on the square rod and located between the pressing plate and the upper plate.

[0014] As an improvement, the limit assembly includes a guide hole coaxially opened on the square rod, two groups of limit holes symmetrically opened on the square rod along the radial direction of the square rod and connected to the guide hole, a limit rod correspondingly slidably arranged in the limit hole, a guide rod slidably and rotatably arranged in the guide hole, an interference rod arranged at the bottom of the guide rod and capable of abutting against the end of the limit rod, a mounting hole opened above the guide hole, a rotating plate arranged at the top of the guide rod, a spring c sleeved on the guide rod and arranged in the mounting hole and below the rotating plate, and positive magnets arranged at the four corners of the top of the square rod and the four corners of the bottom of the rotating plate.

[0015] As an improvement, the end portions of the abutment rod and the limiting rod are transitionally matched.

[0016] As an improvement, the abutting part is made of nylon material.

[0017] The beneficial effects of the present utility model are as follows:

[0018] (1) In the present utility model, the mobile phone shell is placed in the placement bin. Moving the upper plate makes the abutting part abut against the mobile phone shell, and several groups of moving rod assemblies move accordingly. The top thereof can reflect the deformation amount of the mobile phone shell. Then, the protruding moving rod assemblies are pressed, so that the deformed parts of the mobile phone shell can be reshaped, and thus the mobile phone shell can be quickly reshaped, improving the reshaping efficiency;

[0019] (2) In the present utility model, the abutting parts at the bottoms of several groups of moving rod assemblies are in contact. When the moving rod assemblies are pressed, the abutting parts reshape the local contact positions, thus realizing the reshaping of the detailed parts of the mobile phone shell and improving the reshaping effect;

[0020] (3) In the present utility model, after pressing the moving rod assemblies to make the abutting parts press and reshape the mobile phone shell, the rotating plate can be pressed to make the abutting rod abut against the end of the limiting rod. Then, the limiting rod contacts the hole wall of the square hole, so that the moving rod assemblies slowly move upward, realizing the pressure holding after the correction of the mobile phone shell and further improving the reshaping effect.

[0021] In summary, the present utility model has the advantages of simple structure, high correction efficiency and good correction effect, and is especially suitable for the field of mobile phone production equipment. Description of the Drawings

In the description of the present utility model, "a plurality of" means two or more, unless otherwise specifically defined.

[0029] Embodiment:

[0030] As Figure 1 and Figure 2 shown, a correction mold for a mobile phone shell includes:

[0031] A mold base 1, the mold base 1 includes a lower plate 11, a positioning block 12 installed on the lower plate 11, a placement bin 13 opened on the positioning block 12, an upper plate 14 located directly above the positioning block 12 and capable of moving up and down, and an adjustment mechanism 15 for controlling the movement of the upper plate 14;

[0032] A pressing mechanism 2, the pressing mechanism 2 includes a plurality of sets of moving rod assemblies 21 elastically sliding up and down on the upper plate 14, a contact portion 22 provided at the bottom of the moving rod assemblies 21 and capable of contacting the mobile phone shell, and a limiting assembly 23 provided inside the moving rod assemblies 21 and restricting the up and down movement of the moving rod assemblies 21;

[0033] The distribution areas of the plurality of sets of moving rod assemblies 21 are opposite to the placement bin 13. After the contact portion 22 contacts the mobile phone shell, the moving rod assemblies 21 move according to the shape change amount of the mobile phone shell and the mobile phone shell. By pressing the moving rod assemblies 21, the shape change amount of the mobile phone shell can be corrected, and the limiting assembly 23 can keep the moving rod assemblies 21 pressing on the mobile phone shell.

[0034] It should be noted that the placement bin 13 is opened according to the shape of the mobile phone shell.

[0035] Further, the adjusting mechanism 15 includes four sets of columns 151 arranged on the lower plate 11, sliding sleeves 152 installed on the upper plate 14 and correspondingly sleeved on the columns 151, spring a 153 correspondingly sleeved on the columns 151 and located between the sliding sleeves 152 and the lower plate 11, threaded holes 154 correspondingly opened on the sides of the sliding sleeves 152, and set screws 155 threadedly engaged in the threaded holes 154.

[0036] It should be noted that the spring a 153 has a supporting ability, which makes the movement of the upper plate 14 more convenient; the set screw 155 is installed in the threaded hole 154, and when the set screw 155 abuts against the column 151, the sliding sleeve 152 is in a fixed state.

[0037] More importantly, during normal use, in order to improve the fixing efficiency, only the set screw 155 on one of the sliding sleeves 152 can be used for fixing.

[0038] Further, as Figure 2 shown, long strip-shaped observation holes 131 are opened at the four sides of the bottom of the placement bin 13.

[0039] It should be noted that the observation holes 131 are more conducive to observing the fitting condition of the mobile phone shell and the condition of the mobile phone shell after shaping, without having to remove the mobile phone shell from the placement bin 13.

[0040] Further, as Figure 3 and Figure 4 shown, the moving rod assembly 21 includes a square hole 211 opened on the upper plate 14, a square rod 212 slidably arranged up and down in the square hole 211, a pressing plate 213 arranged on the square rod 212, and a spring b 214 sleeved on the square rod 212 and located between the pressing plate 213 and the upper plate 14.

[0041] It should be noted that after several groups of the moving rod assemblies 21 come into contact with the mobile phone shell below, they will copy the shape of the mobile phone shell above, and can display the deformation amount of the mobile phone shell. During correction, pressing the individual protruding square rods 212 can complete the pressing and shaping.

[0042] More importantly, pressing the pressing plate 213 to compress the spring b 214 can make the square rod 212 move downward.

[0043] Further, as Figure 3 and Figure 4As shown, the limiting assembly 23 includes a guide hole 231 coaxially opened on the square rod 212, two groups of limiting holes 232 radially symmetrically opened on the square rod 212 and connected to the guide hole 231, a limiting rod 233 correspondingly slidably arranged in the limiting hole 232, a guide rod 234 slidably and rotatably arranged in the guide hole 231, an interference rod 235 arranged at the bottom of the guide rod 234 and capable of abutting against the end of the limiting rod 233, a mounting hole 236 opened above the guide hole 231, a rotating plate 237 arranged at the top of the guide rod 234, a spring c238 sleeved on the guide rod 234 and arranged in the mounting hole 236 and below the rotating plate 237, and a positive magnet 239 arranged at the four corners of the top of the square rod 212 and the four corners of the rotating plate 237.

[0044] It should be noted that after the square rod 212 moves downward, it presses the rotating plate 237, the spring c238 is compressed, and under the suction force of the positive magnet 239, the resistance rod 235 contacts the limit rod 233, and the resistance rod 235 moves outward and contacts the side wall of the square hole 211, so that the square rod 212 will not rebound, thereby achieving pressure maintenance after the mobile phone shell is pressed.

[0045] It is further necessary to explain that, when the rotating plate 237 is pressed, the positive magnets 239 at the four corners of the top of the square rod 212 and the four corners of the rotating plate 237 are staggered.

[0046] What needs to be explained is that after the shaping is completed, the rotating plate 237 is rotated so that the positive magnet 239 is opposite to each other, and then under the action of repulsion and the spring c238, the guide rod 234 moves upward, and then the resistance rod 235 is disengaged from the limit rod 233, and the square rod 212 will move up and reset under the action of the spring b214.

[0047] Furthermore, the abutment rod 235 is transitionally matched with the end of the limiting rod 233 .

[0048] It should be noted that the transition fit between the end of the resistance rod 235 and the limit rod 233 makes the fit between the resistance rod 235 and the limit rod 233 smoother, and while ensuring the resistance effect between the limit rod 233 and the inner wall of the square hole 211, the square rod 212 can move up smoothly after the limit rod 233 is disengaged from the inner wall of the square hole 211.

[0049] Furthermore, the abutment portion 22 is made of nylon.

[0050] It should be noted that the abutment portion 22 is made of nylon to ensure that the abutment portion 22 will not damage the housing of the mobile phone.

[0051] It should be further explained that the abutment portion 22 is a wearing part and needs to be replaced after being used for a period of time.

[0052] Working process:

[0053] Place the mobile phone shell in the placement bin 13, then adjust the upper plate 14 to a suitable position, and then fix the upper plate 14 by the adjusting mechanism 15. At this time, the abutment portion 22 abuts against the mobile phone shell, and the top of the moving rod assembly 21 reflects the shape of the mobile phone shell. Then, the pressing plate 213 in the individually protruding moving rod assembly 21 allows the abutment portion 22 to correct the deformed mobile phone shell. Then, the rotating plate 237 is pressed, and the spring c238 is compressed. Under the suction force of the positive magnet 239, the abutment rod 235 is in contact with the limiting rod 233. The resistance rod 235 moves outward and contacts the side wall of the square hole 211, so that the square rod 212 will not rebound, thereby achieving pressure maintenance after the mobile phone shell is corrected. Next, the rotating plate 237 is rotated to make the positive magnets 239 face each other, and then under the repulsive effect and the action of the spring c238, the guide rod 234 moves upward, and then the resistance rod 235 is disengaged from the limit rod 233, and the square rod 212 will move up and reset under the action of the spring b214, and then the adjusting mechanism 15 is released and the upper plate 14 is moved upward to take out the mobile phone shell.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
