Manual observation is usually used to determine whether the molding surface of the mold core is scratched, dented or damaged. In the process of manual observation, it is easy to miss small features, or because of unfamiliarity with the model, the missed processing areas cannot be seen. Manual inspection efficiency is low and the inspection error is large. Inspection errors will cause the mold to be unqualified after the mold is assembled and sent to the production line to produce products. The mold needs to be disassembled for reprocessing, which wastes production capacity and reduces production efficiency. Summary of the invention

DETAILED DESCRIPTION
[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0018] like Figure 1-3 As shown, a mold core visual inspection device includes a workbench 1 and a long strip frame 3 arranged on both sides of the workbench 1, a plurality of rollers 4 are arranged between the two frames 3, and a driving motor drives each roller 4 to rotate through a chain sprocket mechanism. Two vertical support rods 6 are fixed at the middle position of each frame 3, and a shell cover is arranged on the outer side of the four support rods 6, and an inlet and an outlet are arranged on the shell cover along the conveying direction. A partition plate is fixed in the middle of the workbench 1, and a vertical cylinder 2 is arranged on the partition plate. The piston rod of the cylinder 2 is connected to a vertical baffle 5, and the baffle 5 is located between two rollers 4 adjacent to a support rod 6, and the thickness of the baffle 5 is less than the distance between the two rollers 4.
[0019] The baffle 5 is used to position the mold core transferred by the roller 4. After the mold core enters the detection area, the cylinder 2 drives the baffle 5 to rise to a fixed position. When the mold core contacts the baffle 5, the roller 4 stops rotating and the mold core is transferred to the position.
[0020] A clamping rail 15 is provided between two support rods 6 on the same frame 3, and a clamping mechanism is slidably connected to the clamping rail 15. The clamping mechanism includes a vertical slideway 14 slidably connected to the clamping rail 15, and a clamping cylinder 16 penetrating the slide table 12 provided on the slideway 14. A vertical pressing plate 13 is connected to the piston rod of the clamping cylinder 16, and a rubber pad is provided inside the pressing plate 13. After the mold core is transferred to the position, the clamping cylinder 16 is controlled to make the pressing plates 13 on both sides close to each other to clamp the mold core. The clamping cylinder 16 can move left and right along the clamping rail 15 and move up and down along the slideway 14 to adapt to mold cores of different sizes.
[0021] The inner side of the four support rods 6 is provided with an electric vertical slide rail 11. The slide seats of the two opposite vertical slide rails 11 perpendicular to the conveying direction are connected with a long strip connecting plate 18. Two electric slide rails 9 are detachably connected between the two connecting plates 18. Two brackets 17 are slidably connected between the two electric slide rails 9. The brackets 17 are slidably connected with a vertical mounting rod 7. The bottom of the mounting rod 7 is rotatably connected with a CCD camera 8. The middle of the mounting rod 7 is detachably connected with a light source 10 above the CCD camera 8. The two CCD cameras 8 can move up and down driven by the slide seats of the vertical slide rails 11, and move closer to or away from each other driven by the brackets 17. At the same time, the CCD camera 8 itself can move forward and backward along the bracket 17, and the CCD camera 8 can swing around the mounting rod 7 to detect different positions of the mold core.
[0022] After the mold core is clamped, the control display device controls the CCD camera 8 to move and take pictures of the mold core. The CCD camera 8 sends the result to the control display device. After processing, the detection image is sent to the display board. The display board also displays the design model of the mold core. By comparing the design model and the detection image, it can be detected whether the mold core has defects.
[0023] A fixing plate 19 is detachably connected to one side of the support rod 6 on each frame 3, and two guide plates 20 are oppositely arranged inside the fixing plate 19. The fixing plate 19 and the guide plates 20 are connected by a screw 21. The distance between the two guide plates 20 gradually narrows along the conveying direction. One end of the screw 21 is connected to the guide plate 20, and the other end of the screw 21 is threadedly connected and passes through the fixing plate 19. The distance between the two guide plates 20 can be adjusted by rotating the screw 21.
[0024] The working principle of the present invention is:
[0025] After the mold core enters the inspection area, the cylinder 2 drives the baffle 5 to rise to a fixed position. When the mold core contacts the baffle 5, the roller 4 stops rotating and the mold core is delivered to the position. Then the clamping cylinder 16 is controlled to make the two side pressure plates 13 close to each other to clamp the mold core. After the mold core is clamped, the control display device controls the CCD camera 8 to move to take pictures of the mold core, and compares the control display device to detect whether the mold core has defects. After the mold core inspection is completed, the cylinder 2 drives the baffle 5 to move down, and then the roller 4 continues to rotate to send the mold core.
[0026] It should be noted that the above embodiments are only used to illustrate the present invention, but the present invention is not limited to the above embodiments. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention fall within the protection scope of the present invention.
