Description

Technical Field

[0001] This utility model relates to the technical field of mold testing devices, specifically to a hardness testing device for mold processing. Background Technology

[0002] As a key process equipment in industrial production, molds are widely used in many fields such as machinery manufacturing, automobiles, aerospace, and electronics. Their quality and performance directly determine the precision, surface quality, and production efficiency of products. Hardness, as one of the core performance indicators of mold materials, plays a decisive role in the wear resistance, strength, toughness, and service life of molds. Currently, in the mold processing process, Rockwell hardness testing devices are used to determine the hardness value based on the depth of indentation plastic deformation.

[0003] However, during the hardness testing process, since the indentations are generally small, the process of manually checking and finding the indentations is time-consuming, especially when the testing area is large and the number of testing points is large. Staff need to scan the testing area one by one, which consumes a lot of time and energy.

[0004] Based on this, the present invention designs a hardness testing device for mold processing to solve the above problems. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a hardness testing device for mold processing.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A hardness testing device for mold processing includes a hardness tester. A connecting block is mounted on the surface of the hardness tester, and an indenter is provided on the surface of the connecting block.

A marking component for marking test points is provided on the outer side of the connecting block. The marking component includes a mounting sleeve fitted on the outer surface of the connecting block, and a marker pen refill is provided on the bottom surface of the mounting sleeve. A circumferentially distributed toothed block is fixedly connected to the bottom of the outer surface of the mounting sleeve. A toothed disc that meshes with the toothed block is provided on one side of the mounting sleeve. A fixing ring is fixedly mounted on the hardness tester, and a motor is fixedly connected to the surface of the fixing ring. The output end of the motor is fixed to the center of the toothed disc via a shaft.

[0008] Furthermore, the bottom surface of the mounting sleeve is provided with circumferentially distributed notches, and an electric telescopic rod is fixedly connected to the top surface of the inner wall of the notch. The number of marker refills is the same as that of the electric telescopic rod, and the bottom surface of the telescopic end of the electric telescopic rod is fixedly connected to the top surface of the marker refill. Each marker refill is a different color.

[0009] Furthermore, the mounting sleeve is a cylindrical structure that is smaller at the top and larger at the bottom, and the diameter of the top surface of the mounting sleeve is smaller than the diameter of the connecting block, and the mounting sleeve and the connecting block are rotatably connected by a bearing.

[0010] Furthermore, the surface of the worktable of the hardness tester is provided with an installation port, and a support plate is provided above the opening of the installation port.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] In some embodiments, please refer to the accompanying drawings. Figures 1-6A hardness testing device for mold processing includes a hardness tester 1, a connecting block 2 mounted on the surface of the hardness tester 1, an indenter 3 disposed on the surface of the connecting block 2, a worktable disposed on the surface of the hardness tester 1, with the connecting block 2 and the indenter 3 facing the worktable, a clamping mechanism disposed on the worktable, and a marking component for marking test points disposed on the outer side of the connecting block 2, the marking component including a mounting sleeve 4 sleeved on the outer surface of the connecting block 2, a marker pen refill 7 disposed on the bottom surface of the mounting sleeve 4, and a fixed bottom surface of the outer surface of the mounting sleeve 4. The tester 1 is fixedly connected with circumferentially distributed toothed blocks 8. A toothed disc 9 that meshes with the toothed blocks 8 is provided on one side of the mounting sleeve 4. A fixing ring 11 is fixedly installed on the hardness tester 1. A motor 10 is fixedly connected to the surface of the fixing ring 11, and the output end of the motor 10 is fixed at the center of the toothed disc 9 through a shaft. In use, the test surface can be marked with a marker pen refill 7. At the same time, the cooperation between the toothed blocks 8 and the toothed disc 9 allows the marked area to be drawn in a circle with the indenter 3 as the center, improving visual accuracy and thus improving the quality inspection efficiency after the test.

[0027] The clamping mechanism is an existing threaded rod guide clamping structure, which will not be described in detail here.

[0028] In some embodiments, such as Figures 1-6 As shown in the preferred embodiment of this utility model, the bottom surface of the mounting sleeve 4 has circumferentially distributed notches 5. An electric telescopic rod 6 is fixedly connected to the top surface of the inner wall of the notch 5. The number of marker refills 7 is the same as that of the electric telescopic rod 6, and the bottom surface of the telescopic end of the electric telescopic rod 6 is fixedly connected to the top surface of the marker refill 7. Each marker refill 7 has a different color. When using this device, the extension length of the marker refill 7 can be adjusted by using the electric telescopic rod 6. In addition, different colored marker refills 7 can mark different inspection surfaces on the mold surface. At the same time, with the rotatable effect of the mounting sleeve 4, the color of the marker refill 7 can be easily changed.

[0029] In some embodiments, such as 1- Figure 6 As shown, in a preferred embodiment of the present invention, the mounting sleeve 4 is a cylindrical structure with a smaller top and a larger bottom, and the top diameter of the mounting sleeve 4 is smaller than the diameter of the connecting block 2. The mounting sleeve 4 and the connecting block 2 are rotatably connected by a bearing, which facilitates the stability of the mounting sleeve 4 when it is mounted on the outer surface of the connecting block 2.

[0030] In some embodiments, such as Figures 1-5As shown, in a preferred embodiment of this utility model, the surface of the worktable of the hardness tester 1 is provided with an installation port 13. A support plate 12 is provided above the opening of the installation port 13. The clamping mechanism is located on the surface of the support plate 12. Both sides of the inner wall of the installation port 13 are provided with racks 17 fixed to the bottom surface of the support plate 12. The bottom surface of the racks 17 is meshed with gears 16. An operating rod 15 is fixedly connected between the two gears 16. One end of the operating rod 15 extends through the side wall of the hardness tester 1. The surface of the worktable of the hardness tester 1 is provided with a scale 14 located on one side of the support plate 12. The scale 14 and the operating rod 15 are located on the same side of the hardness tester 1, which can enable the support plate 12 to move horizontally, thereby allowing the clamped mold to move the testing surface. The accuracy of the position movement is improved by using the operation of the scale 14, the operating rod 15, the gears 16, and the racks 17.

[0031] In some embodiments, such as Figure 5 As shown, in a preferred embodiment of this utility model, guide blocks 19 are fixedly connected to the opposite sides of the two racks 17. Symmetrical guide openings 18 are provided on the inner wall of the mounting opening 13, and the two ends of the guide openings 18 do not penetrate the mounting opening 13. The guide blocks 19 are slidably connected to the guide openings 18. By rotating the operating rod 15, the gear 16 and the rack 17 are meshed and moved. During the process, the sliding connection between the guide openings 18 and the guide blocks 19 can be used to maintain the stability of movement. At the same time, the structure of not penetrating at both ends can prevent the racks 17 from slipping out of the mounting opening 13.

[0032] In some embodiments, such as Figures 3-5 As shown, in a preferred embodiment of this utility model, the operating lever 15, gear 16, and guide block 19 are all arranged on the center line of the mounting port 13. By arranging the operating lever 15, gear 16, and guide block 19 on the center line of the mounting port 13, the initial position of the tray 12 can be located in the middle of the worktable of the hardness tester 1, maintaining the centering of the initial test, and facilitating the subsequent movement of the tray 12 to both sides.

[0033] In some embodiments, such as Figures 3-4 As shown, in a preferred embodiment of this utility model, the operating rod 15 has a thread 20 at one end near the hardness tester 1, and a fastening sleeve 21 is fitted on the surface of the thread 20. The fastening sleeve 21 is threadedly connected to the thread 20 on the surface of the operating rod 15. This structure ensures that the part of the operating rod 15 without the thread 20 is easy to rotate by hand. After rotation, the operating rod 15 can be held steady by hand before the fastening sleeve 21 is tightened onto the surface of the thread 20, and one side is attached to the side wall of the hardness tester 1 to maintain the stability of the rack 17 at its current position.

[0034] The above-mentioned mold processing hardness testing device is used as follows: Place the mold to be tested on the surface of the tray 12, fix the mold by the clamping mechanism, then start the hardness tester 1 so that the indenter 3 can test the hardness of the mold surface. During the process, start the motor 10 to drive the gear plate 9 to rotate, and drive the mounting sleeve 4 to rotate around the connecting block 2 through the gear block 8. At this time, the marker pen core 7 draws a circle on the mold surface with the indenter 3 as the center to mark the test position and form a colored circular mark. After the test is completed, the staff can quickly locate the indentation position by the colored circular mark and confirm the test result. According to the above single position test process, the hardness test and marking of the first test point of the mold is completed.

[0035] When the mold position needs to be moved for testing, loosen the fastening sleeve 21 on the operating lever 15, rotate the operating lever 15 to drive the gear 16 to rotate, and through the meshing action of the rack 17 and the gear 16, make the support plate 12 move smoothly to the right. During the process, the scale 14 can be used to display the moving distance. Then, tighten the fastening sleeve 21 again at the stationary position to make it fit against the side wall of the hardness tester 1 and lock the position of the support plate 12. Then, retract the current red marker pen refill by using the electric telescopic rod 6 and extend the marker pen refill of another color. Repeat the hardness testing process.

[0036] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
