Description

Technical Field

[0001] This utility model relates to the field of hardness testing technology for automotive mold parts, and in particular to a hardness testing device for automotive mold parts. Background Technology

[0002] Automotive molds are categorized into stamping molds, injection molds, and die-casting molds. Stamping molds utilize the pressure of stamping equipment to separate or plastically deform sheet metal through the mold, thereby obtaining automotive parts of the required shape and size. Injection molds inject molten plastic into the mold cavity, which then cools and solidifies to form the desired shape. Die-casting molds inject liquid metal into the mold cavity at high pressure and speed, which then cools and solidifies to form automotive parts. All of these automotive molds are composed of parts, which are an important component of automotive molds, and their quality and precision directly affect the production quality of automotive parts.

[0003] Therefore, it is necessary to test the hardness of automotive mold parts. If the hardness of automotive mold parts does not meet the standard, it can easily cause damage to the automotive mold. When testing the hardness of automotive mold parts, a certain load is applied to press a hardened steel ball of a certain size into the material surface and hold it for a period of time. After the load is removed, the ratio of the load to the area of ​​the indentation is the Brinell hardness value.

[0004] However, the material properties of different parts of automotive mold components vary, and different parts of automotive mold components may undergo different processing techniques, resulting in differences in hardness. Therefore, when testing the hardness of automotive mold components, it is necessary to test different positions of the automotive mold components. After testing one part of the automotive mold component, it is necessary to remove the automotive mold component and re-fix it to change the testing position, which reduces the testing speed of automotive mold components. Based on the above problems, this application proposes a hardness testing device for automotive mold components. Utility Model Content

[0022] Reference Figure 1-5A hardness testing device for automotive mold parts includes a mounting base 1. A lateral moving assembly is mounted on the top of the mounting base 1. A placement plate 6 is mounted on the top of the mounting base 1 via the lateral moving assembly. Two electric clamps 29 are fixedly mounted on the top of the placement plate 6, arranged symmetrically. The electric clamps 29 facilitate the fixation of the automotive mold parts, preventing movement during testing. An L-shaped plate 7 is fixedly mounted on the top of the mounting base 1.

A pressure sensor 28 is attached to the top of the sliding column 26. The adjustment assembly includes a U-shaped plate 19, which is fixedly mounted on the bottom of the mounting plate 18. A forward / reverse motor 20 is fixedly mounted on the left side of the U-shaped plate 19. A screw 21 is fixedly mounted at the output end of the forward / reverse motor 20. A threaded sleeve 22 is threaded onto the surface of the screw 21. A mounting bracket 25 is fixedly mounted on the bottom of the threaded sleeve 22. A guide sleeve 23 is fixedly mounted on the top of the threaded sleeve 22. A guide rail 24 slides inside the guide sleeve 23 and is fixedly mounted on the upper side wall of the U-shaped plate 19. The forward / reverse motor 20 drives the screw 21 to rotate, and the threaded sleeve 22, through the mounting bracket 25, drives the sliding column 26 and the pressure sensor 28. The force sensor 28 moves and limits and guides the threaded sleeve 22 through the guide sleeve 23 and guide rail 24, and drives the ball 27 to move through the moving column 26, thereby changing the position of the pressure applied to the automotive mold parts, thus adjusting the detection position of the automotive mold parts. The pressure sensor 28 is fixedly installed on the upper side wall of the mounting bracket 25. The rotary lifting assembly includes a drive motor 8 and a hydraulic push rod 9. Both the drive motor 8 and the hydraulic push rod 9 are fixedly installed on the top of the L-shaped plate 7. The output end of the drive motor 8 is fixedly provided with a connecting cylinder 10. A movable sleeve 11 is slidably provided on the surface of the connecting cylinder 10. A limiting groove 12 is opened inside the movable sleeve 11. A limiting protrusion 13 is slidably provided inside the limiting groove 12. The limiting protrusion 13 is fixedly installed. A rotating plate 14 is fixedly mounted on the surface of the connecting cylinder 10. A circular slide rail 15 is fixedly mounted on the surface of the rotating plate 14. A fixed sliding sleeve 16 is slidably mounted on the surface of the circular slide rail 15. A connecting rod 17 is fixedly mounted on the top of the fixed sliding sleeve 16. The connecting rod 17 is fixedly mounted on the output end of the hydraulic push rod 9. There are four limiting grooves 12 and four limiting protrusions 13, and the four limiting grooves 12 and four limiting protrusions 13 are arranged in a circular array. The connecting cylinder 10 is driven by the drive motor 8 to rotate the moving sleeve 11 through the limiting grooves 12 and limiting protrusions 13, so that the rotating plate 14 drives the circular slide rail 15 to rotate inside the fixed sliding sleeve 16, so that the mounting plate 18 drives the mounting frame 25 to rotate through the adjusting component.This causes the mounting bracket 25 to move the movable column 26 and the pressure sensor 28, and the movable column 26 to move the ball bearing 27, allowing for further adjustment of the ball bearing 27's position. This enables pressure testing at more locations on the automotive mold components.

[0023] Specifically, the lateral movement component includes an electric push rod 2 and a connecting slide rail 4. Both the electric push rod 2 and the connecting slide rail 4 are fixedly installed on the top of the mounting base 1.

A connecting sleeve 5 is slidably installed on the surface of the connecting slide rail 4. The connecting sleeve 5 is fixedly installed on the top of the placement plate 6. There are two connecting slide rails 4 and two connecting sleeves 5, and they are symmetrically distributed. The electric push rod 2 drives the output end to move the connecting plate 3, and the connecting plate 3 drives the placement plate 6 to move. This causes the placement plate 6 to slide the connecting sleeve 5 on the surface of the connecting slide rail 4, allowing the electric clamp 29 on the left side of the placement plate 6 to enter the interior of the L-shaped plate 7, or the electric clamp 29 on the right side of the placement plate 6 to enter the interior of the L-shaped plate 7. The electric clamp 29 then drives the automotive mold parts into the interior of the L-shaped plate 7, enabling continuous feeding and continuous testing of the automotive mold parts, thus increasing the speed of the automotive mold parts hardness testing device.

[0024] The hardness testing device for the automotive mold parts is connected to a 220V mains power supply, and the main controller can be a conventional known device such as a computer for control.

[0025] In use: Place the automotive mold parts to be inspected onto the electric clamp 29. The electric clamp 29 clamps and fixes the automotive mold parts. The hydraulic push rod 9 drives the output end to push the connecting rod 17 downward. The connecting rod 17 drives the circular slide rail 15 downward through the fixed sliding sleeve 16, and the circular slide rail 15 drives the rotating plate 14 downward, so that the moving sleeve 11 slides on the surface of the connecting cylinder 10, and the limiting groove 12 and the limiting protrusion 13 slide relative to each other, so that the rotating plate 14 drives the U-shaped plate 19 downward through the mounting plate 18. The U-shaped plate 19 carries... The moving screw 21 and guide rail 24 move downwards, causing the screw 21 and guide rail 24 to drive the screw sleeve 22 and guide sleeve 23 to move downwards. The screw sleeve 22 then drives the mounting bracket 25 to move downwards, causing the moving column 26 to drive the ball bearing 27 into contact with the automotive mold component. This causes the ball bearing 27 to apply pressure to the automotive mold component. Since forces are mutual, the ball bearing 27 applies pressure to the detection end of the pressure sensor 28 through the moving column 26. Once the pressure detected by the pressure sensor 28 reaches the applied pressure standard, it is maintained for a period of time. After unloading, the ratio of the load to the indentation area is the automotive mold component's pressure. When testing the hardness of different locations on automotive mold components, the screw 21 is rotated by the forward and reverse motor 20, causing the screw sleeve 22 to slide on the guide slide rail 24 along the guide sleeve 23. The screw sleeve 22 moves the moving column 26 and pressure sensor 28 via the mounting bracket 25, and the ball bearing 27 moves via the moving column 26. The output end of the drive motor 8 then rotates the connecting cylinder 10. The connecting cylinder 10 rotates the moving sleeve 11 via the limiting groove 12 and limiting protrusion 13, causing the moving sleeve 11 to rotate the rotating plate 14. The rotating plate 14 drives the circular slide rail 15 to rotate inside the fixed slide sleeve 16, and the rotating plate 14 drives the mounting plate 18 to rotate. The mounting plate 18 drives the screw 21 and guide slide rail 24 to rotate through the U-shaped plate 19, so that the screw 21 and guide slide rail 24 drive the screw sleeve 22 and guide slide sleeve 23 to rotate, and the screw sleeve 22 drives the mounting frame 25 to rotate, so that the mounting frame 25 drives the moving column 26 and pressure sensor 28 to move, and the moving column 26 drives the ball 27 to move, so that the position of the ball 27 can be adjusted again, and different positions of the automotive mold parts can be detected.
