The other end of 11 is fixedly connected to the left end of the limit block 12, the outer wall of the lower mold 3 is provided with a plurality of limit grooves 13, the outer wall of the limit block 12 is snap-fitted with the inner wall of the limit groove 13, the inner wall of the mounting seat a2 penetrates and is slidably connected with a guide rod 10, the right end of the guide rod 10 is fixedly connected to the left end of the limit block 12, the outer wall of the guide rod 10 is fixedly connected with a connecting plate 8, the buckle assembly is fixedly connected with the connecting plate 8, the connecting plate 8 connects the multiple groups of guide rods 10 together, the outer wall of the connecting plate 8 is fixedly connected with a pull rod 9, and the pull rod 9 is pulled outward to make the connecting plate 8 drives all the guide rods 10 to move outward together, causing the limit block 12 to squeeze the reset spring a11 and shrink it into the groove of the mounting seat a2, and release the clamping connection with the limit groove 13 on the lower mold 3. At this time, the lower mold 3 can be slid out or installed along the mounting seat a2. After it is completely taken out or installed, release the pull rod 9. The elastic force generated by the deformation of the reset spring a11 will push the limit block 12 to reset, and re-clamp it into the limit groove 13 to fix the lower mold 3, solving the problem of the troublesome fixed bolts that are constantly rotated at this stage.
[0027] See also Figure 3-Figure 4The outer wall above the base 1 is slidably connected with a measuring board 14. When processing flexible circuit boards in batches, due to the lack of experience of some employees, it is not possible to ensure that the bending area is uniform each time the circuit board is placed on the lower mold 3, resulting in the scrapping of the bent circuit board. Therefore, a measuring board 14 is set. Inexperienced staff can move the measuring board 14 to a suitable position. After that, each time the circuit board is placed, it is pushed to the bottom to contact the measuring board 14, which can well control the bending position of each group of circuit boards. The inner wall of the measuring board 14 is elastically connected with a columnar block 17 through a reset spring b16. One end of the reset spring b16 is connected to the measuring board 17.

The position of the measuring plate 14 can be adjusted according to the circuit boards in different positions that need to be bent, so that new employees can make judgments conveniently.
[0028] Working principle: Replace the upper and lower sets of molds according to the bending angle of the circuit board, pull the pull rod 9 outward, so that the connecting plate 8 drives the guide rod 10 to move the limit block 12 outward until it is disengaged from the limit groove 13. At this time, the lower mold 3 can be removed along the protruding structure of the mounting seat a2, and the upper mold 7 is the same. After replacing the appropriate mold, release the pull rod 9, and the reset spring a11 pushes the limit block 12 to reset and re-engage it in the limit groove 13 to fix the mold. Then, adjust the measuring plate 14 according to the position of the circuit board that needs to be bent, lift the handle 15 upward to disengage the column block 17 from the slot 18, and then move the measuring plate 14 horizontally. When it moves to the appropriate position, release the handle 15, and the reset spring b16 pushes the column block 17 back into the slot 18 to fix the measuring plate 14, which is convenient for the staff to make judgments, ensure that the bending area of each circuit board is the same, and ensure the product qualification rate.
