[0023] like Figures 1 to 8 As shown, in this embodiment, the utility model includes an upper mold 1 and a lower mold 2, the upper mold 1 and the lower mold 2 are hinged by a rotating shaft 3, the upper mold 1 includes an upper mold frame 11, an upper mold needle plate 12 and a plurality of cylinders 13, a plurality of the cylinders 13 are arranged at one end inside the rotating end of the upper mold frame 11, and a plurality of movable ends of the cylinders 13 are connected by a movable plate 14, and push plates 15 are arranged at both ends of the movable plate 14, and a plurality of inclined grooves 151 are arranged in the middle of the push plate 15, and the low points of the plurality of inclined grooves 151 are close to the The cylinder 13, a plurality of sliding shafts 16 are arranged on both sides of the upper mold needle plate 12, and a plurality of vertical sliding grooves 17 are also arranged inside the two sides of the upper mold frame 11, and a plurality of the sliding shafts 16 pass through a plurality of the inclined grooves 151 and are connected with a plurality of the vertical sliding grooves 17, the lower mold 2 includes a lower mold frame 21 and a lower mold needle plate 22, and the lower mold needle plate 22 is arranged at the upper end of the lower mold frame 21, and a plurality of the cylinders 13 drive the upper mold needle plate 12 to cooperate with the lower mold needle plate 22 through a plurality of the push plates 15. It can be seen that the two groups of cylinders 13 push the two groups of rotating plates 15 to press the upper mold needle plate 12 downward, connect the electronic board on the lower mold needle plate 22 with the upper mold needle plate 12 and test it. The plurality of vertical sliding grooves 17 and the plurality of inclined grooves 151 enable the cylinder 13 to convert the lifting movement of the upper mold needle plate 12 through horizontal pushing, thereby realizing the compression, connection and separation of the electronic board. There is no need for a vertical lifting device to press down, and the space requirement is smaller.

[0024] like Figure 3As shown, in this embodiment, both sides of the upper end of the lower mold frame 21 are provided with a shaft support plate 23, the shaft 3 is provided at one end of the shaft support plate 23, and the upper mold frame 11 is rotatably matched with the shaft support plates 23 on both sides of the upper end of the lower mold frame 21 through a plurality of shafts 3. It can be seen that the shaft 3 enables the upper mold 1 and the lower mold 2 to achieve relative rotation, so that the upper mold 1 can be opened more easily for material discharge and material removal.

The sliding shafts 16 move on the inclined shafts 151 and the vertical sliding grooves 17 to press the upper mold needle plate 12 down to contact and conduct with the electronic board. The electronic board is tested by the resistance transfer plate. After the test is completed, the cylinder 13 drives the push plate 15 to restore the initial position, the upper mold needle plate 12 rises, the upper mold 1 and the lower mold 2 are unlocked, the upper mold 1 is opened, the electronic board that has been tested is taken out, and a new electronic board to be tested is put in, and the above steps are repeated to complete the long-line flat push pneumatic backplane detection.
