Description

Technical Field

[0001] The utility model relates to the technical field of mold making, in particular to hardness testing equipment for raw materials used in mold making. Background Art

[0002] At present, molds are usually made of steel, and in the production of some molds, there are requirements for the hardness of the steel itself, so hardness testing equipment is needed for testing. Hardness tester, also known as hardness tester, is mainly used to test the hardness of materials. This is an important material performance indicator that can reflect the ability of materials to resist hard objects pressing into its surface. Hardness tester can measure the hardness of metals and other materials. Its measurement range is wide, and usually the detection head applies a certain force to the surface of the object to be tested for detection.

[0003] At present, the existing hardness testing equipment for mold making raw materials cannot be adjusted during testing, and the testing head can only move vertically up and down. Therefore, it can only test the raw materials in the center of the testing table. However, when testing irregularly shaped mold materials, some parts may be inconvenient to test, so it is necessary to move the detectable part of the mold raw material to the center of the testing table. Since the position of the testing table is small, it will cause the center of gravity to be unstable, resulting in unstable detection. At the same time, the inability to adjust the machine head reduces the convenience of use and the detection limitations, which greatly reduces the practicality of the hardness testing equipment for mold making raw materials. Summary of the invention

[0004] The main purpose of the utility model is to solve the above existing technical problems and provide a hardness testing device for raw materials used in mold making.

[0005] The specific scheme of the utility model is: a hardness testing device for raw materials for mold making, comprising a body and a head, a testing head is provided at the bottom of the head, a testing platform is provided on the body and is located below the testing head, a connecting block is provided at the bottom of the head, the connecting block is connected to a movable mechanism, the movable mechanism enables the head to be movable, the movable mechanism comprises a dovetail groove, the dovetail groove is provided at the top of the body, a slider is slidably connected in the dovetail groove, a bearing a is embedded in the slider, the bearing a is fixedly connected to the connecting block, a driving mechanism is provided at the bottom of the slider, the driving mechanism is used to drive the slider to move, so that the head can be driven, a fixing mechanism is provided on the head, and the fixing mechanism is used to fix the head to rotate.

[0006] According to the above technical solution, the slider is driven to move in the dovetail groove by the driving mechanism, so as to achieve the effect of moving the position of the machine head forward and backward. At the same time, the machine head can be rotated in the bearing a through the connecting block, so as to achieve the effect of rotating the machine head.

[0007] Furthermore, the fixing mechanism includes a thread groove, which passes through the machine head and extends downward to pass through the connecting block. A threaded rod is threadedly connected to the thread groove. The threaded rod is longer than the thread groove so that the threaded rod can contact the sliding block. The thread groove is coaxial with the connecting block.

[0008] According to the above technical solution, a threaded connection is made in the threaded groove through a threaded rod, and the bottom end of the threaded rod passes through the connecting block and through the bearing a to contact the slider to achieve a limiting effect, thereby increasing the friction between the threaded rod and the slider and preventing the bearing a from rotating.

[0009] Furthermore, a movable groove is connected to the lower part of the dovetail groove, and the driving mechanism includes a moving block, which is arranged at the bottom end of the slider and movably connected to the movable groove. A screw rod passes through the moving block and is threadedly connected. Both ends of the screw rod are rotatably connected to the inner wall of the fuselage respectively, and a bevel gear a is provided on the surface of the screw rod. The bevel gear a is meshed with the bevel gear b, and a bearing c is provided on one side of the bevel gear b. A rocker is provided at one end of the bevel gear b, and the end of the rocker rod away from the bevel gear b passes through the bearing c and extends outside the fuselage.

[0010] According to the above technical solution, the rocker rotates in the bearing c to drive the bevel gear b, which in turn drives the bevel gear a to rotate, and finally the bevel gear a drives the screw to rotate, so that the moving block moves on the screw to achieve the effect of driving the machine head to move.

[0011] Furthermore, the bevel gear a is arranged at the left end of the screw rod, so that the moving distance of the moving block on the screw rod is consistent with the moving distance of the slider in the dovetail groove.

[0012] According to the above technical solution, by arranging the bevel gear a on the left side of the screw, a movable space is provided for the right side of the screw to avoid being blocked by the bevel gear a, so that the movable distance of the moving block on the screw is consistent with the moving distance of the slider in the dovetail groove.

[0013] Compared with the prior art, the utility model has the following advantages: the hardness testing equipment for mold making raw materials is installed with a movable mechanism, which can effectively adjust the position and angle of the machine head, avoiding the unstable center of gravity caused by the traditional testing method that needs to move the mold raw material testing part to the middle of the testing table for testing when testing irregular mold raw materials, thereby improving the convenience and adaptability of the hardness testing equipment for mold making raw materials to detect mold raw materials of different shapes.

DETAILED DESCRIPTION

[0020] See also Figure 1-5 The present embodiment is a hardness testing device for mold making raw materials, which is composed of a fuselage 1, a head 2 and other structures. A detection head 3 is installed at the bottom of the head 2, and the detection head 3 is used to contact the mold raw material to achieve the detection effect. A detection platform 4 is provided on the fuselage 1 and the detection platform 4 is located directly below the detection head 3. The head 2 is fixedly installed with the detection head 3, and the detection head 3 is connected with a movable mechanism. The movable mechanism can make the head 2 rotate left and right and move forward and backward. The movable mechanism includes a dovetail groove 5, which is arranged at the top of the fuselage 1. A slider 6 matching with it is slidably connected inside the dovetail groove 5. A bearing a7 is inlaid inside the slider 6, and the bearing a7 is fixedly connected to the connecting block 8. A driving mechanism is installed at the bottom of the slider 6. The driving mechanism is used to drive the slider 6 to move, so that the fuselage 1 can move left and right. A fixing mechanism is installed on the top of the head 2, and the fixing mechanism is used to fix the fuselage 1 to prevent the fuselage 1 from rotating by itself.

[0021] Furthermore, the fixing mechanism includes a threaded groove 9, which vertically penetrates the head 2 from the top of the fuselage 1 and extends downward through the connecting block 8. A threaded rod 10 is connected to the inner thread of the threaded groove 9. The length of the threaded rod 10 is longer than that of the threaded groove 9, so that the threaded rod 10 can contact the slider 6, thereby achieving the effect of fixing the fuselage 1. The threaded groove 9 is coaxial with the connecting block 8, so that the threaded rod 10 can contact the slider 6 and limit the position.

[0022] Furthermore, the lower part of the dovetail groove 5 is connected with a movable groove 11, and the movable groove 11 is used for driving the mechanism to move inside it. The driving mechanism includes a moving block 12, which is welded to the bottom end of the slider 6 and can move in the movable groove 11. A screw rod 13 passes through the middle of the moving block 12 and is threadedly connected to the moving block 12. Both ends of the screw rod 13 are rotatably connected to bearings b14 welded to the inner wall of the fuselage 1. A bevel gear a15 is fixed on the surface of the screw rod 13. The bevel gear a15 is meshed with the bevel gear b16 to achieve a transmission effect. A bearing c17 is installed on one side of the bevel gear b16, and the bearing c17 is fixed to the inner wall of the fuselage 1. A rocker 18 is fixed to one end of the bevel gear b16, and the end of the rocker 18 away from the bevel gear b16 passes through the bearing c17 and extends outside the fuselage 1, so that the operator can turn the rocker 18 conveniently.

[0023] Furthermore, the bevel gear a15 is arranged at the left end of the screw rod 13, so that the moving distance of the right end of the screw rod 13 becomes longer, avoiding the moving block 12 from being affected by the bevel gear a15 when moving, so that the moving distance of the moving block 12 on the screw rod 13 is consistent with the moving distance of the slider 6 on the dovetail groove 5.

[0024] The working principle of this embodiment is as follows: when detecting irregularly shaped mold materials, since the place where the mold materials are convenient for detection is not located at the center of the detection table 4, the rocker 18 can be rotated forward. At this time, the rocker 18 rotates on the bearing c17, thereby driving the bevel gear b16 to rotate. When the bevel gear b16 rotates, it drives the bevel gear a15 to rotate. At this time, the bevel gear a15 drives the screw rod 13 to rotate on the bearings b14 at both ends. At this time, the screw rod 13 performs a rotational motion in the moving block 12, so that the moving block 12 performs a linear movement on the screw rod 13, just like the principle of a ball screw. When the moving block 12 moves on the screw rod 13, it drives the top slider 6 to move in the dovetail groove 5. At this time, the slider 6 drives the connecting block 8 to drive the head 2 to move on the fuselage 1 to achieve the effect of adjusting the position of the head 2 front and back. When the fuselage 1 reaches the appropriate position, stop turning the rocker 18. When the head 2 needs to move in the opposite direction, just turn the rocker 18. When adjusting the angle of the head 2, The machine head 2 can be directly rotated by manpower. At this time, the machine head 2 moves on the bearing a7 through the connecting block 8, so as to achieve the effect of rotating the machine head 2. When the detection head 3 is aligned with the part of the mold material that needs to be detected after reaching the appropriate angle, the threaded rod 10 is rotated to move the threaded rod 10 in the thread groove 9 until the threaded rod 10 cannot rotate, so that the bottom end of the threaded rod 10 contacts the slider 6, thereby increasing the friction between the threaded rod 10 and the slider 6. Therefore, the connection block 8 can be effectively prevented from rotating in the bearing a7 to achieve the effect of fixing the rotation of the machine head 2. When the angle needs to be adjusted again, the threaded rod 10 is rotated conversely to separate the threaded rod 10 from the slider 6 to avoid hard friction, and the machine head 2 can be rotated again, which greatly improves the convenience and adaptability of the hardness detection equipment for mold manufacturing materials. When measuring irregular mold materials, the measurement can be performed by moving the machine head 2 to avoid the unstable center of gravity of the mold material after moving the mold material, thereby affecting the measurement stability.
