[0029] like Figure 1-5 As shown, the present invention has the following specific embodiments.

[0030] Example:

[0031] A hardness testing device for mold production includes a testing platform 1 and a positioning seat 3. Rotating rods 2 are rotatably connected to both ends of the top of the testing platform 1. A fixed plate 21 is fixedly connected to one end of each rotating rod 2, and a second helical gear 22 is fixedly connected to the other end. The positioning seat 3 is fixedly connected to the testing platform 1 via a fixed column 31. The positioning seat 3 is used for positioning and clamping the mold via a movable plate 4. A clamping rod 41 is fixedly connected to one end of the movable plate 4. The device also includes:

[0032] The hydraulic cylinder 5 has a punch head 51 fixedly connected to its telescopic end, and the punch head 51 is used to apply pressure to the mold.

[0033] Camera 6 is used to inspect the mold;

[0034] The power mechanism is used to drive the hydraulic cylinder 5 and the camera 6 to alternate positions.

[0035] By adopting the above technical solution, when using the device, the mold to be tested is first placed into the positioning seat 3. The clamping rod 41 on the movable plate 4 can clamp and fix the mold. Then, the hydraulic cylinder 5 is opened to push the stamping head 51 down to stamp the mold for testing. After stamping, the power mechanism is opened to drive the hydraulic cylinder 5 and the camera 6 to switch positions, so that the camera 6 can take pictures of the stamped mold. The pictures taken are compared with those before stamping for testing. The structure is reasonable, which facilitates the positioning and stamping of the mold, and also facilitates quick picture taking and testing.

[0036] Specifically, the bottom of the positioning seat 3 is provided with three limiting ports 34, and a slide rod 341 is fixedly connected inside the limiting port 34, and the movable plate 4 is slidably connected to the slide rod 341.

[0037] Three lead screws 32 are rotatably connected to the fixed column 31. One end of the lead screw 32 is rotatably connected to the fixed column 31. The end of the lead screw 32 extending into the fixed column 31 is fixedly connected to a third helical gear 321. The other end of the lead screw 32 is threaded into the movable plate 4. A second servo motor 33 is fixedly connected to the bottom of the fixed column 31. The fourth helical gear 331 fixed to the output shaft of the second servo motor 33 meshes with the third helical gear 321.

[0038] By adopting the above technical solution, the second servo motor 33 can drive the fourth helical gear 331 to rotate, the fourth helical gear 331 can drive the meshing third helical gear 321 to rotate, the third helical gear 321 can drive the lead screw 32 to rotate on the fixed column 31, the lead screw 32 can drive the threaded movable plate 4 to slide on the slide rod 341, the movable plate 4 can drive the clamping rod 41 to move, and the three movable plates 4 can clamp and position the middle mold.

[0039] Specifically, the hydraulic cylinder 5 is connected through the rotating rod 2 at the left end of the testing platform 1, and the camera 6 is suspended from the rotating rod 2 at the right end of the testing platform 1.

[0040] The power mechanism includes a hanger 12, a transmission rod 13, and a first servo motor 14. The hanger 12 is fixedly connected to the bottom of the testing table 1. The transmission rod 13 is connected through the hanger 12 and the hanger 12 and the transmission rod 13 are rotatably engaged. Both ends of the transmission rod 13 are fixedly connected to a first helical gear 131, and a second helical gear 22 is meshed with the first helical gear 131. A worm gear 132 is fixedly connected to the middle of the transmission rod 13. The first servo motor 14 is fixedly connected to the bottom of the hanger 12. The worm 141 fixed to the output shaft of the first servo motor 14 is meshed with the worm gear 132.

[0041] An L-shaped limiting rod 23 is fixedly connected to the rotating rod 2. Semi-circular sliding grooves 11 are provided at both ends of the top of the detection table 1, and the L-shaped limiting rod 23 slides in cooperation with the semi-circular sliding grooves 11.

[0042] By adopting the above technical solution, the hydraulic cylinder 5 and the camera 6 can be driven to switch positions. Specifically, the first servo motor 14 of the power mechanism can drive the worm gear 141 to rotate, the worm gear 141 can drive the meshing worm wheel 132 to rotate, the worm wheel 132 can drive the transmission rod 13 to rotate on the hanger 12, and the transmission rod 13 can drive the first helical gears 131 at both ends to rotate. Since the first helical gear 131 is meshed with the second helical gear 22, and the second helical gear 22 is connected to the rotating rod 2, which rotates on the inspection table 1, both rotating rods 2 can be driven to rotate on the inspection table 1 simultaneously. The rotating rods 2 can drive the fixed plate 21 to rotate. Furthermore, since the hydraulic cylinder 5 and the camera 6 are respectively suspended on the two fixed plates 21, ... Figure 4 As shown, the hydraulic cylinder 5 is located directly above the positioning seat 3. When the power mechanism drives the two rotating rods 2 to rotate counterclockwise by 180° simultaneously, the hydraulic cylinder 5 moves away from the positioning seat 3. At this time, the camera 6 rotates to directly above the positioning seat 3. When the power mechanism drives the rotating rods 2 to rotate clockwise by 180° again, the hydraulic cylinder 5 and the camera 6 are reset. That is, the hydraulic cylinder 5 is located directly above the positioning seat 3, and the camera 6 moves away from the positioning seat 3. This facilitates the control of the hydraulic cylinder 5 and the camera 6 to switch positions, so that after the mold is extruded and tested, the camera 6 can take pictures for comparison and testing.

[0043] During the rotation of the rotating rod 2, the L-shaped limiting rod 23 fixed on the rotating rod 2 can slide within the semi-circular slide groove 11 to limit the rotation, which facilitates the positioning of the rotating rod 2.
