Description

Technical Field

[0001] The utility model relates to the technical field of mold detection, in particular to a mold wear resistance detection device. Background Art

[0002] A mold is a tool that forms a blank into a specific shape and size under the action of external forces. It is widely used in blanking, die forging, cold heading, extrusion, powder metallurgy pressing, pressure casting, and compression or injection molding of engineering plastics, rubber, ceramics, and other products. The mold has a specific contour or internal cavity shape. To test the wear resistance of a mold, it is usually necessary to first polish the mold and then observe the wear morphology, width, and depth of the wear scars.

[0003] Existing technology, such as the utility model disclosed in patent publication number CN219038596U, discloses a mold wear resistance detection device, which includes a base frame, a support frame fixedly connected to the upper surface of the base frame, a servo motor fixedly mounted on the upper surface of the support frame, a drive turntable fixedly connected to the output end of the servo motor, a first support rod rotatably mounted on one side of the base frame, a second support rod rotatably mounted inside the first support rod, a fixed plate fixedly connected to the surface of the second support rod, and a rolling rod rotatably connected to one side of the fixed plate. The drive turntable is driven to rotate by the servo motor, and the roller is driven to roll by the belt and belt roller, thereby causing the grinding belt to rotate and enable the grinding belt to grind the inner cavity of the mold. The fixed plate is provided with an elliptical shape to facilitate entry into the inner cavity of the mold so that the grinding belt contacts the cavity wall. The rolling rod can roll within the fixed plate, so that the running grinding belt can grind the cavity wall.

[0004] During use, the width of the grinding belt is fixed, which makes it difficult for the grinding belt to contact and grind the mold cavity wall whose width is smaller than the grinding belt width.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0027] like Figures 1 to 5 As shown, the utility model is a mold wear resistance detection device, comprising: a base 1, a bracket 6 fixedly mounted on the base 1, a wear mechanism installed between the brackets 6, and a pushing mechanism installed on the base 1.

[0028] The wear mechanism includes: an active roller 11, a driven roller 13, and a grinding belt 16; the active roller 11 is connected to a second motor 14 that drives it to rotate through a roller; the driven roller 13 is rotatably installed at the bottom of the support member, and the support member is composed of an inner rod 19 installed by a hinged fixed plate 17, an outer rod 18 slidably installed on the inner rod 19, a second support spring 21 fixedly connecting the inner wall of the outer rod 18 and the inner rod 19, and a mounting shell 20 fixedly installed at the bottom of the outer rod 18, that is, the driven roller 13 is rotatably installed on the mounting shell 20; the mounting plate is fixedly connected to the two brackets 6; a fixed frame 7 is fixedly installed on the bracket 6, and the position height of the fixed frame 7 is higher than the fixed plate 17; a limit rod 8 is fixedly installed in the fixed frame 7, and two moving blocks 9 are slidably installed on the limit rod 8. That is, the two moving blocks 9 are slidably installed in the fixed frame 7, and the moving blocks 9 are fixedly connected to the inner wall of the fixed frame 7 through the first support spring 10, and the first support spring 10 is installed around the limit rod 8; the moving blocks 9 on the two brackets 6 are connected through the fixed rod 15, and the fixed rod 15 is rotatably installed with a pulley 12; the grinding belt 16 is rotatably installed on the active roller 11, the pulley 12 and the driven roller 13.

[0029] By setting up multiple narrower grinding belts 16, the grinding belts 16 can be in contact with the inner cavity of the mold through the support member, and the mold is subjected to wear tests by using multiple grinding belts 16, so as to facilitate the detection of the wear resistance of molds of different sizes. The narrower grinding belts 16 can contact the inner cavities of molds of different widths. The lowest end of the grinding belt 16 is supported by the driven roller 13, and the driven roller 13 is supported by the support member. When the grinding belt 16 contacts the inner cavity of the mold, the mold will push the driven roller 13 upward, and the outer rod 18 slides up on the inner rod 19. The inner rod 19 and the outer rod 18 compress the second supporting spring 21. The elastic force of the second supporting spring 21 pushes the outer rod 18, and the outer rod 18 pushes the mounting shell 20 and the driven roller 13 to make the grinding belt 16 close to the inner cavity of the mold. While the support member makes part of the grinding belt 16 close to the inner cavity of the mold, it can also adjust the position of other parts of the grinding belt 16 by its deflection, so that the grinding belt 16 can adapt to molds of different sizes.

[0030] In the present invention, the first support spring 10 is in a stretched state. When the second support spring 21 is compressed, the height of the driven roller 13 rises. The first support spring pulls the moving block 9 to slide toward the two ends of the limit rod 8 in the fixed frame 7. The moving block 9 drives the fixed rod 15 to move away from the pulley 12 on the fixed rod 15, and the grinding belt 16 is tensioned through the pulley 12 to prevent the grinding belt 16 from loosening and slipping off the driven roller 13 and the pulley 12.

[0031] Abrasive particles of different materials are evenly arranged on different grinding belts 16. Some grinding belts 16 can extend into the inner cavity of the mold to perform wear tests on the inner cavity of the mold. Wear tests on the inner cavity of the mold using abrasive particles of multiple materials can improve the reliability of the test results.

[0032] The pushing mechanism includes: a threaded rod 2 rotatably installed in a groove on one side of the base 1, a guide rod 5 fixedly installed in a groove on the other side of the base 1, a first motor 4 that drives the threaded rod 2 to rotate, and the rotating shaft of the first motor 4 is fixedly connected to the threaded rod 2; a detection platform 3 is threadedly installed on the threaded rod 2, and the detection platform 3 is slidably installed on the guide rod 5. By placing the mold on the detection platform 3 and starting the first motor 4, the rotating shaft of the first motor 4 drives the threaded rod 2 to rotate, so that the detection platform 3 drives the mold to move. During the movement of the mold, the wear mechanism wears the mold.

[0033] Working principle:

[0034] Place the mold on the inspection table 3, start the first motor 4, the shaft of the first motor 4 drives the threaded rod 2 to rotate, so that the inspection table 3 drives the mold to move, start the second motor 14, the shaft of the second motor 14 drives the active roller 11 to rotate through the roller, and the active roller 11 drives the grinding belt 16 to move. When the inspection table 3 drives the mold to contact the grinding belt 16, the mold is pushed upward by the driven roller 13, the outer rod 18 slides on the inner rod 19, the inner rod 19 and the outer rod 18 compress the second support spring 21, and the first support spring pulls the moving block 9 to the limit in the fixed frame 7. The two ends of the rod 8 slide, and the moving block 9 drives the fixed rod 15 to move away from the pulley 12 on the fixed rod 15, and the grinding belt 16 is tensioned by the pulley 12. The elastic force of the second support spring 21 pushes the outer rod 18, and the outer rod 18 pushes the mounting shell 20 and the driven roller 13, so that the grinding belt 16 is tightly attached to the inner cavity of the mold. The inner rod 19 on the support member contacted by the grinding belt 16 that does not contact the inner cavity of the mold is deflected, so that this part of the grinding belt 16 contacts the outer wall of the mold, so that the grinding belt 16 can adapt to molds of different sizes, which is convenient for testing the wear resistance of molds of different sizes.
