Description

Technical Field

[0001] This application relates to the field of workpiece trimming technology, specifically to a trimming mechanism and a mold. Background Technology

[0002] Currently, in the manufacturing process of micro-sized mobile phone parts, due to the strict requirements on the size specifications of the parts, continuous die bending is usually used first, and then a side-push trimming mechanism is used to push the bent corner edges of the parts to ensure the accuracy of the parts. Current side-push trimming mechanisms mainly use push rods on the upper die to push multiple sliders to slide within the lower die to side-push the bent corner edges of the parts. However, this type of side-push trimming mechanism has a complex structure, occupies a large space, and the push rods and multiple sliders rub frequently, resulting in significant wear, which affects the trimming accuracy of the parts. Utility Model Content

[0003] In view of the above, it is necessary to propose a trimming mechanism and mold that occupies less space in order to improve the trimming accuracy of the workpiece.

[0004] This application provides a trimming mechanism for trimming a workpiece. The workpiece includes a first part and a second part arranged at an angle to the first part.

The fixed seat is disposed within the lower mold, and the rotating member is rotatably disposed within the fixed seat. The rotating member has a pushing end for being pushed by the pressing assembly and a trimming surface for trimming the second part of the workpiece. The trimming surface is disposed opposite to the side of the supporting assembly. When the pushing end is pushed by the pressing assembly, the rotating member rotates, causing the trimming surface to move towards the side of the supporting assembly and abut against the second part of the workpiece, thereby trimming the workpiece.

[0007] A height adjustment component is slidably disposed within the upper mold, and one end of the component has a second inclined surface that abuts against the first inclined surface of the pressure component. The moving direction of the height adjustment component is perpendicular to the moving direction of the pressure component. When the height adjustment component slides within the upper mold, it pushes against the first inclined surface through the second inclined surface, so that the pressure component moves along the mold closing direction of the upper mold and the lower mold.

[0008] In one possible implementation, the pressing assembly further includes:

[0017] A support member is slidably disposed within the lower mold to support the first part of the workpiece, and the second part of the workpiece is located on the side of the support member;

[0018] A second elastic element is disposed inside the lower mold, and the two ends of the second elastic element abut against the lower mold and the bearing element, respectively.

[0019] In one possible implementation, the side of the support member is provided with a sliding portion, and the support assembly further includes:

[0020] A support base is provided with a sliding groove, the shape of which is adapted to the shape of the bearing member and the sliding part, and the bearing member and the sliding part are slidably disposed in the sliding groove.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0036] The following will describe some embodiments of this application in detail with reference to the accompanying drawings.

[0037] Please see Figure 1 and Figure 2 This application provides a mold 100, including an upper mold 10, a lower mold 20, and a trimming mechanism 30.

[0038] The upper mold 10 and the lower mold 20 are compatible and both are plate-shaped structures.

[0039] The trimming mechanism 30 is used to trim the workpiece 200, which includes a first part 210 and a second part 220 arranged at an angle to the first part 210. In this embodiment, the angle between the first part 210 and the second part 220 is 90 degrees. The trimming mechanism 30 includes a pressing assembly 31, a bearing assembly 32, and a rotating assembly 33.

[0040] Please see also Figure 3 The pressing assembly 31 is disposed inside the upper mold 10 and one end of it extends out of the upper mold 10. The bearing assembly 32 is disposed inside the lower mold 20 adapted to the upper mold 10 and is used to bear the first part 210 of the workpiece 200. The second part 220 of the workpiece 200 is located on the side of the bearing assembly 32. The rotating assembly 33 is disposed within the lower mold 20. The rotating assembly 33 includes a fixed base 331 and a rotating member 332. The fixed base 331 is disposed within the lower mold 20, and the rotating member 332 is rotatably disposed within the fixed base 331. The rotating member 332 has a pushing end 3321 for being pushed against by the pressing assembly 31 and a trimming surface 3322 for trimming the second part 220 of the workpiece 200. The trimming surface 3322 is disposed opposite to the side of the bearing assembly 32. When the pushing end 3321 is pushed against by the pressing assembly 31, the rotating member 332 rotates so that the trimming surface 3322 moves toward the side of the bearing assembly 32 and abuts against the second part 220 of the workpiece 200, thereby trimming the workpiece 200.

[0041] In the solution provided in this application embodiment, when the upper mold 10 and the lower mold 20 are closed, the pressing component 31 pushes the pushing end 3321 of the rotating component 332 to rotate, so that the trimming surface 3322 of the rotating component 332 moves toward the side of the bearing component 32 and abuts the second part 220 of the workpiece 200, thereby trimming the workpiece 200. The whole structure is relatively simple, occupies less space, and the rotating component 332 will not generate much wear (rotational friction) when rotating, and the trimming accuracy of the workpiece 200 is high.

[0042] Please continue reading Figure 3 In one possible implementation, the pressure assembly 31 includes a pressure member 311 and a height adjustment member 312. The pressure member 311 is rod-shaped, slidably disposed within the upper mold 10 with one end extending out of the upper mold 10, and has a first inclined surface 3111 at the end of the pressure member 311 within the upper mold 10; the height adjustment member 312 is slidably disposed within the upper mold 10, and has a second inclined surface 3121 at one end that abuts against the first inclined surface 3111 of the pressure member 311. The moving direction of the height adjustment member 312 is perpendicular to the moving direction of the pressure member 311. When the height adjustment member 312 slides within the upper mold 10, it pushes against the first inclined surface 3111 through the second inclined surface 3121, so that the pressure member 311 moves along the mold closing direction of the upper mold 10 and the lower mold 20. By setting the height adjustment component 312, the position of the pressure component 311 in the mold closing direction of the upper mold 10 and the lower mold 20 can be adjusted, so that the trimming surface 3322 abuts against the second part 220 of the workpiece 200 and trims the workpiece 200, resulting in a better trimming effect.

[0043] In one possible implementation, the pressure assembly 31 further includes a guide 313, which is a block structure and is fixedly disposed within the upper mold 10. The pressure member 311 slides through the guide 313, and one end of the pressure member 311 located within the upper mold 10 is provided with a retaining part 3112, which is also a block structure and is movably disposed between the guide 313 and the height adjustment member 312. By providing the guide 313, the movement of the pressure member 311 along the mold closing direction of the upper mold 10 and the lower mold 20 can be guided; by providing the retaining part 3112, the pressure member 311 can be prevented from slipping off the upper mold 10.

[0044] In one possible implementation, the guide member 313 has a receiving groove 3131 on the side facing the holding part 3112. The pressing assembly 31 also includes a first elastic member 314, which is disposed in the receiving groove 3131. The two ends of the first elastic member 314 abut against the bottom of the receiving groove 3131 and the holding part 3112, respectively. In this embodiment, the first elastic member 314 is a spring. By providing the first elastic member 314, the holding part 3112 can be moved and the height adjustment member 312 can be reset.

[0045] In one possible implementation, the height adjustment member 312 includes an adjustment part 3122, a fixing part 3123, and a rotating part 3124. The adjustment part 3122 is plate-shaped and slidably disposed within the upper mold 10, with a second inclined surface 3121 disposed at one end of the adjustment part 3122. The fixing part 3123 is fixedly disposed within the upper mold 10 and is disposed opposite to the adjustment part 3122. The rotating part 3124 is rotatably disposed on the fixing part 3123, with one end of the rotating part 3124 passing through the fixing part 3123 and abutting against the adjustment part 3122. When rotating, the rotating part 3124 can move on the fixing part 3123 and push the adjustment part 3122 to move. In this embodiment, the rotating part 3124 is a bolt. By providing an adjustment part 3122, a fixing part 3123, and a rotating part 3124, the rotating part 3124 can be rotated, thereby causing the rotating part 3124 to push the adjustment part 3122 to move, and thus adjusting the position of the pressing member 311.

[0046] In one possible implementation, the support assembly 32 includes a support member 321 and a second elastic member 322. The support member 321 is generally block-shaped and slidably disposed within the lower mold 20, serving to support a first portion 210 of the workpiece 200, wherein a second portion 220 of the workpiece 200 is located on the side of the support member 321. The second elastic member 322 is disposed within the lower mold 20, with its two ends abutting against the lower mold 20 and the support member 321, respectively. In this embodiment, the second elastic member 322 is a spring. By providing the second elastic member 322, the support member 321 can be reset after the workpiece 200 has been trimmed.

[0047] In one possible implementation, the support member 321 has a sliding portion 3211 on its side, which is generally strip-shaped. The support assembly 32 also includes a support base 323, which is cuboid in shape and has a groove 3231. The shape of the groove 3231 is adapted to the shapes of the support member 321 and the sliding portion 3211, and the support member 321 and the sliding portion 3211 are slidably disposed within the groove 3231. By providing the support base 323, the movement of the support member 321 and the sliding portion 3211 can be guided, resulting in high movement accuracy.

[0048] In one possible implementation, the fixed base 331 has a receiving groove 3311, which is generally arc-shaped. The rotating component 332 includes a rotating body 3323 and a trimming part 3324. The rotating body 3323 is generally arc-shaped and is rotatably disposed within the receiving groove 3311 and adapted to the shape of the receiving groove 3311. The pushing end 3321 is located at the end of the rotating body 3323 away from the bottom of the receiving groove 3311. The trimming part 3324 is located on one side of the rotating body 3323 and is disposed opposite to the bearing component 32. The trimming surface 3322 is disposed on the trimming part 3324. By providing the rotating body 3323 and the trimming part 3324, the rotating body 3323 can rotate within the receiving groove 3311, and during the rotation of the rotating body 3323, the trimming surface 3322 abuts against the second part 220 of the workpiece 200.

[0049] In one possible implementation, the fixed base 331 has a through hole 3312 communicating with the receiving groove 3311. The rotating assembly 33 also includes a third elastic element 333, which is disposed within the through hole 3312. One end of the third elastic element 333 abuts against the lower mold 20, and the other end abuts against the rotating body 3323 near the pushing end 3321. In this embodiment, the third elastic element 333 is a spring. By providing the third elastic element 333, the rotating component 332 can be reset after the workpiece 200 has been adjusted.

[0050] The implementation process of the mold 100 in this embodiment is as follows:

[0051] Initially, workpiece 200 is located on the strip, and the strip frame is above the lower die 20;

[0052] The upper die 10 moves toward the lower die 20, the upper die 10 abuts against the material strip and moves the workpiece 200 on the material strip to the support member 321, wherein the support member 321 carries the first part 210 of the workpiece 200, and the second part 220 of the workpiece 200 is located on the side of the support member 321.

[0053] The upper mold 10 continues to move toward the lower mold 20, and the pressure member 311 begins to contact the pushing end 3321 of the rotating body 3323. The rotating body 3323 rotates in the receiving groove 3311 of the fixed seat 331, causing the trimming surface 3322 of the rotating member 332 to move toward the side of the bearing assembly 32 and abut against the second part 220 of the workpiece 200, thereby trimming the second part 220 of the workpiece 200, i.e. the corner edge of the workpiece 200.

[0054] The upper mold 10 moves away from the lower mold 20, and under the action of the second elastic element 322 and the third elastic element 333, the bearing element 321 and the rotating body 3323 are reset.
