Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of PCB board molds, and particularly relates to a PCB board mold with accurate upper and lower mold alignment. Background Technique
[0002] A PCB board, whose Chinese name is printed circuit board, also known as printed wiring board, is an important electronic component, a support for electronic components, and a carrier for electrical connection of electronic components. Generally, a PCB board can be processed and manufactured through a mold. The alignment accuracy and stability of the PCB board mold have a crucial impact on product quality.
[0003] The PCB board is stamped and processed in the mold. During the production process, the upper mold contacts and stamps the lower mold. The stamping will collide with the lower mold, and the impact generated by the collision will cause the PCB board in the mold to shake, resulting in the surface circuits of the board being unable to be accurately aligned, thus causing a short circuit in the circuit, seriously affecting the electrical performance of the PCB board, and the produced PCB board cannot be used normally. Therefore, we have proposed a PCB board mold with accurate upper and lower mold alignment. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a PCB board mold with accurate upper and lower mold alignment. By setting a fixing component, the fixation of raw materials is completed. When the PCB board is stamped by the upper mold, it can remain stable without shaking, so that it can be accurately positioned with the hole positions of the mold, solving the problem that the existing CB board is stamped and processed in the mold. During the production process, the upper mold contacts and stamps the lower mold, and the stamping will collide with the lower mold. The impact generated by the collision will cause the PCB board in the mold to shake, resulting in the surface circuits of the board being unable to be accurately aligned, thus causing a short circuit in the circuit, seriously affecting the electrical performance of the PCB board, and the produced PCB board cannot be used normally.
[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:
[0006] The utility model relates to a PCB board mold with precise alignment of the upper and lower molds, which includes a workbench and a fixing component. The fixing component includes a turning handle. A lead screw is fixedly connected to the left side of the turning handle. A fixing block is threadedly connected to the outer surface of the lead screw. A rotating circular block is fixedly connected to the right side of the turning handle. An active clamping block is rotatably connected to the outer surface of the rotating circular block. A fixed clamping block is fixedly connected to the top of the bottom mold. Two limiting rods are fixedly connected to the right side of the active clamping block. Two sliding holes are formed inside the fixing block. The inner walls of the two sliding holes are all slidably connected to the outer surface of the limiting rod. A machine housing is fixedly connected to the top of the workbench. An inclined block is arranged inside the machine housing. The bottom mold is slidably connected to the top of the workbench. A motor is fixedly connected to the front of the workbench. By setting the fixing component, specifically, turning the turning handle drives the lead screw to rotate clockwise, driving the rotating circular block to rotate inside the active clamping block. The active clamping block functions to enable the lead screw to rotate inside the active clamping block while driving the active clamping block to move. As the lead screw rotates, it pushes the active clamping block to move leftward to contact the raw material, completing the fixation of the raw material. When the PCB board is stamped by the upper mold, it can remain stationary, so that it can be accurately positioned with the hole positions of the mold.
[0007] Further, the number of the inclined blocks is two. Plug rods are fixedly connected to the mutually remote sides of the two inclined blocks. Springs are sleeved on the outer surfaces of the two plug rods. Grooves are formed on the left side and the right side of the bottom mold. The inner walls of the two grooves are all plugged with the outer surfaces of the inclined blocks. By setting the inclined blocks, specifically, when the bottom mold contacts the inclined blocks, it pushes the two inclined blocks to move away from each other. The inclined blocks compress the springs to generate opposite elastic forces. When the grooves formed on the left side and the right side of the bottom mold move to the inclined blocks, the elastic forces generated by the springs push the inclined blocks into the grooves. At this time, the bottom mold moves to directly below the top mold. The inclined blocks align the position of the bottom mold with the top mold, enabling the PCB raw material board placed on the bottom mold to be accurately aligned with the top mold, ensuring the quality of the PCB board finished product.
[0008] Further, through holes are formed on the left side and the right side of the machine housing. The inner walls of the two through holes are all slidably connected to the outer surfaces of the plug rods. Stopping blocks are fixedly connected to the mutually remote sides of the two plug rods. By setting the stopping blocks, the plug rods are prevented from detaching from the machine housing.
[0009] Further, a screw rod is fixedly connected to the output end on the back of the motor. The outer surface of the screw rod is rotatably connected to the inner wall of the workbench. A sliding groove is formed inside the workbench. A sliding block is slidably connected to the inner wall of the sliding groove. A threaded hole is formed inside the sliding block. The inner wall of the threaded hole is threadedly connected to the outer surface of the screw rod. The top of the sliding block is fixedly connected to the top of the bottom mold. By setting the sliding block to drive the bottom mold to move on the workbench, it is convenient to pick up and place the PCB board.
[0010] Further, an oil cylinder is fixedly connected to the top of the casing. The output end of the bottom of the oil cylinder is fixedly connected to a top mold. Two connecting rods are fixedly connected to the top of the top mold. Two round holes are provided in the top of the casing. The inner walls of the two round holes are slidably connected to the outer surfaces of the connecting rods. Two limiting rings are fixedly connected to the tops of the two connecting rods. By arranging the connecting rods, the top mold can be kept stable during the movement process.
[0011] Further, four calibration holes are provided in the inner wall of the top mold. The four calibration holes are distributed at the four corners of the top mold. Four calibration rods are fixedly connected to the top of the bottom mold. The outer surfaces of the four calibration rods are inserted into the calibration holes. A mold groove is provided in the top of the bottom mold. The four calibration rods fixed to the top of the bottom mold are inserted into the calibration holes of the top mold. When the calibration rods and the calibration holes are not aligned, the stamping is stopped in time. After maintenance, when the calibration rods and the calibration holes are aligned, the PCB board can be stamped and produced.
[0012] The utility model has the following beneficial effects:
[0013] 1. By arranging the fixing component in the utility model, specifically, turning the handle drives the lead screw to rotate clockwise, driving the rotating circular block to rotate inside the movable clamping block. The movable clamping block enables the lead screw to rotate inside the movable clamping block while driving the movable clamping block to move. As the lead screw rotates, the movable clamping block is pushed to move leftward to contact the raw material, completing the fixation of the raw material. When the PCB board is stamped by the upper mold, it can be kept from shaking, so that it can be accurately positioned with the hole positions of the mold.
[0014] 2. By arranging the inclined blocks in the utility model, specifically, when the bottom mold contacts the inclined blocks, the two inclined blocks on both sides are pushed away from each other. The inclined blocks squeeze the springs to generate opposite elastic forces. When the grooves provided on the left and right sides of the bottom mold move to the inclined blocks, the elastic forces generated by the springs push the inclined blocks into the grooves. At this time, the bottom mold moves to directly below the top mold. The inclined blocks align the position of the bottom mold with the top mold, enabling the PCB raw material board placed on the bottom mold to be accurately aligned with the top mold, ensuring the quality of the finished PCB board.
[0015] Of course, it is not necessary for any product implementing the utility model to simultaneously achieve all the above-mentioned advantages. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of this utility model.
[0025] Please refer to Figures 1-5As shown in the figure, the utility model is a PCB board mold with precise alignment of the upper and lower molds, including a workbench 11 and a fixing component 4. The fixing component 4 includes a turning handle 44. A lead screw 43 is fixedly connected to the left side of the turning handle 44. A fixing block 41 is threadedly connected to the outer surface of the lead screw 43. A rotating circular block 47 is fixedly connected to the right side of the turning handle 44. A movable clamping block 42 is rotatably connected to the outer surface of the rotating circular block 47. A fixed clamping block 46 is fixedly connected to the top of the bottom mold 18. Two limiting rods 45 are fixedly connected to the right side of the movable clamping block 42. Two sliding holes are opened inside the fixing block 41. The inner walls of the two sliding holes are all slidably connected to the outer surface of the limiting rod 45. A machine shell 12 is fixedly connected to the top of the workbench 11. An inclined block 31 is arranged inside the machine shell 12. The bottom mold 18 is slidably connected to the top of the workbench 11. A motor 15 is fixedly connected to the front of the workbench 11. By setting the fixing component 4, specifically, turning the turning handle 44 drives the lead screw 43 to rotate clockwise, driving the rotating circular block 47 to rotate inside the movable clamping block 42. The movable clamping block 42 enables the lead screw 43 to keep rotating inside the movable clamping block 42 while driving the movable clamping block 42 to move. As the lead screw 43 rotates, it pushes the movable clamping block 42 to move leftward to contact the raw material, completing the fixation of the raw material. When the PCB board is stamped by the upper mold, it can remain stationary, so that it can be accurately positioned with the hole positions of the mold.
[0026] There are two inclined blocks 31. Plug rods 32 are fixedly connected to the mutually remote sides of the two inclined blocks 31. Springs 33 are sleeved on the outer surfaces of the two plug rods 32. Grooves are opened on the left side and the right side of the bottom mold 18. The inner walls of the two grooves are all plugged with the outer surfaces of the inclined blocks 31. By setting the inclined blocks 31, specifically, when the bottom mold 18 contacts the inclined blocks 31, it pushes the two inclined blocks 31 to move away from each other. The inclined blocks 31 compress the springs 33 to generate opposite elastic forces. When the grooves opened on the left side and the right side of the bottom mold 18 move to the inclined blocks 31, the elastic forces generated by the springs 33 push the inclined blocks 31 into the grooves. At this time, the bottom mold 18 moves to directly below the top mold 22. The inclined blocks 31 align the position of the bottom mold 18 with the top mold 22, enabling the PCB raw material board placed on the bottom mold 18 to be accurately aligned with the top mold 22, ensuring the quality of the PCB board finished product.
[0027] Through holes are opened on the left side and the right side of the machine shell 12. The inner walls of the two through holes are all slidably connected to the outer surfaces of the plug rods 32. Stopping blocks 34 are fixedly connected to the mutually remote sides of the two plug rods 32.
[0028] The output end of the back of the motor 15 is fixedly connected to a screw rod 16. The outer surface of the screw rod 16 is rotatably connected to the inner wall of the workbench 11. A sliding groove is opened inside the workbench 11. A sliding block 17 is slidably connected to the inner wall of the sliding groove.
[0029] A threaded hole is opened inside the sliding block 17. The inner wall of the threaded hole is threadedly connected to the outer surface of the screw rod 16. The top of the sliding block 17 is fixedly connected to the top of the bottom mold 18.
[0030] An oil cylinder 13 is fixedly connected to the top of the casing 12. The output end at the bottom of the oil cylinder 13 is fixedly connected to a top die 22. Two connecting rods 23 are fixedly connected to the top of the top die 22. Two circular holes are opened at the top of the casing 12. The inner walls of the two circular holes are slidably connected to the outer surfaces of the connecting rods 23. A limiting ring 21 is fixedly connected to the tops of the two connecting rods 23.
[0031] Four calibration holes are opened in the inner wall of the top die 22. The four calibration holes are distributed at the four corners of the top die 22. Four calibration rods 19 are fixedly connected to the top of the bottom die 18. The outer surfaces of the four calibration rods 19 are inserted into the calibration holes. A die groove 14 is opened at the top of the bottom die 18.
[0032] A specific application of this embodiment is as follows: Put the raw material on the surface of the bottom die 18. Rotate the turning handle 44 to drive the lead screw 43 to rotate clockwise, driving the rotating circular block 47 to rotate inside the movable clamping block 42. The movable clamping block 42 enables the lead screw 43 to drive the movable clamping block 42 to move while keeping rotating inside the movable clamping block 42. As the lead screw 43 rotates, the movable clamping block 42 is pushed to move leftward to contact the raw material, completing the fixation of the raw material. When the PCB board is being stamped by the upper die, it can remain stationary, so that it can be accurately positioned with the hole positions of the mold. Turn on the motor 15 to drive the screw 16 to rotate clockwise, driving the sliding block 17 to move backward, thereby driving the bottom die 18 to move backward. When the bottom die 18 contacts the inclined blocks 31, the two inclined blocks 31 on both sides are pushed away from each other. The inclined blocks 31 compress the springs 33 to generate opposite elastic forces. When the grooves opened on the left and right sides of the bottom die 18 move to the inclined blocks 31, the elastic forces generated by the springs 33 push the inclined blocks 31 into the grooves. Stop the operation of the motor 15. At this time, the bottom die 18 moves to directly below the top die 22. The inclined blocks 31 are provided to align the position of the bottom die 18 with the top die 22. The PCB raw material board placed on the bottom die 18 can be accurately aligned with the top die 22, ensuring the quality of the PCB board finished product. Turn on the oil cylinder 13 to push the top die 22 to move downward. The connecting rods 23 provided at the top of the top die 22 slide in the circular holes opened in the casing 12. By providing the connecting rods 23, the top die 22 remains stable during the movement. Four calibration holes are opened at the four corners of the top die 22. As the top die 22 moves downward, the four calibration rods 19 fixed to the top of the bottom die 18 are inserted into the calibration holes of the top die 22. When the calibration rods 19 and the calibration holes are not aligned, stop the stamping in time. After maintenance, when the calibration rods 19 and the calibration holes can be aligned, then carry out the stamping production of the PCB board.
