[0001] This utility model relates to the field of mold design technology, and in particular to a measuring device for mold design. Background Technology

[0002] In the modern mold manufacturing field, the demand for high-precision and complex molds is increasing. As an important process equipment for manufacturing various products, the quality and precision of molds directly affect the performance and quality of the final products. With the continuous development of the manufacturing industry, the design and manufacturing of molds are becoming increasingly complex, and the requirements for their dimensional accuracy, shape accuracy and surface quality are also getting higher and higher. The measuring device used for mold design is a key tool in the mold manufacturing process, mainly used to accurately obtain various dimensions, shapes and positional parameters of the mold.

[0003] Due to the complexity of the mold shape, existing measuring devices cannot fully fit the fixed probes to the measuring surface, resulting in measurement errors. Probes with fixed angles and positions cannot reach some hidden and special locations of the mold, leading to missing measurement data. When measuring different parts, it is necessary to frequently reposition the mold and measuring device, which consumes a lot of time. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides a measuring device for mold design, which aims to improve the problem of inaccurate data when measuring molds with complex shapes using existing measuring devices.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a measuring device for mold design, comprising a base plate, three cylinders fixedly connected to the top of the base plate, a connecting frame fixedly connected between the output ends of the three cylinders, two moving parts provided on the top of the connecting frame, each of the two moving parts having a first sliding groove on its top, a moving block slidably connected between the two first sliding grooves, two second motors fixedly connected to the bottom of the moving block, a rotating part fixedly provided at the output end of the second motor on the left, the rotating part being rotatably connected to the moving block, a worm gear fixedly provided at the output end of the second motor on the right, a worm wheel meshing with the bottom of the worm gear, the worm wheel being rotatably connected to the rotating part, a rotating part fixedly connected between the front and rear sides of the worm wheel, a measuring head fixedly connected to the bottom of the rotating part, and two fixing components provided on the top of the base plate for fixing the mold.

[0006] Preferably, the fixing component includes a fixing plate, which is fixedly connected to the base plate. A second sliding groove is provided on the left side of the fixing plate, and a sliding block is slidably connected in the second sliding groove. A gear is rotatably connected to the bottom of the inner wall of the sliding block, and a ratchet is fixedly connected to the top of the gear. A pawl is tightly fitted to the right side of the ratchet, and the pawl is rotatably connected to the sliding block. The front side of the pawl extends through and to the front side of the sliding block, and a tension spring is fixedly connected to the right side of the pawl. The right end of the tension spring is fixedly connected to the inner wall of the sliding block.

[0007] Preferably, a rack is meshed with the left side of the gear, and the rack is fixedly connected to the fixing plate.

[0008] Preferably, each of the sliding blocks has a pointer fixedly connected to its top, and each of the fixed plates has a scale line on its left side.

[0009] Preferably, a limiting plate is fixedly connected to the right side of the sliding block.

[0010] Preferably, a first motor is fixedly connected to both the front and right sides of the connecting frame, and threaded rods are fixedly provided at the output ends of both first motors.

[0011] Preferably, one adjacent end of each of the two threaded rods is rotatably connected to the connecting frame, and both threaded rods are threadedly connected to adjacent moving parts.

[0012] Preferably, the two fixing components are mirrored on the diagonal of the base plate.

[0013] This utility model has the following beneficial effects: 1. In this utility model, the second motor on the left drives the rotating part to rotate, thereby adjusting the front and rear angles of the measuring head. The second motor on the right drives the worm gear to rotate, thereby driving the worm wheel and the rotating part to rotate, thereby adjusting the left and right angles of the measuring head, thus enabling measurement of the template from various angles.

[0014] 2. In this utility model, by pushing the sliding block to slide in the second slide groove, the gear rotates on the rack, which in turn drives the ratchet at the top to rotate. Since the pawl is tightly engaged with the ratchet under the action of the tension spring, the ratchet and the gear can only rotate in one direction, thereby fixing templates of different sizes. At the same time, the length and width of the template can be quickly measured by the pointer and scale. Attached Figure Description

[0017] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a measuring device for mold design, comprising a base plate 1, three cylinders 2 fixedly connected to the top of the base plate 1, a connecting frame 3 fixedly connected between the output ends of the three cylinders 2, two moving parts 6 provided on the top of the connecting frame 3, each of the two moving parts 6 having a first sliding groove 7 on its top, a moving block 8 slidably connected between the two first sliding grooves 7, two second motors 16 fixedly connected to the bottom of the moving block 8, a rotating part 18 fixedly provided at the output end of the left second motor 16, the rotating part 18 being rotatably connected to the moving block 8, a worm gear 17 fixedly provided at the output end of the right second motor 16, a worm wheel 19 meshing with the bottom of the worm gear 17, the worm wheel 19 being rotatably connected to the rotating part 18, a rotating part 20 fixedly connected between the front and rear sides of the worm wheel 19, a measuring head 21 fixedly connected to the bottom of the rotating part 20, and two fixing components provided on the top of the base plate 1 for fixing the mold.

[0019] Specifically, the three cylinders 2 drive the top connecting frame 3 to rise and fall, so that the measuring head 21 is closer to the mold, thus making the measurement values ​​more accurate. The second motor 16 on the left drives the rotating part 18 to rotate, thereby adjusting the front and rear angle of the measuring head 21. The second motor 16 on the right drives the worm gear 17 to rotate, thereby driving the worm wheel 19 and the rotating part 20 to rotate, thereby driving the measuring head 21 to adjust the left and right angle, thus realizing the measurement of the template from various angles.

[0020] Reference Figure 3 The fixing assembly includes a fixing plate 9, which is fixedly connected to the base plate 1. A second sliding groove 11 is provided on the left side of the fixing plate 9. A sliding block 13 is slidably connected in the second sliding groove 11. A gear 22 is rotatably connected to the bottom of the inner wall of the sliding block 13. A ratchet 23 is fixedly connected to the top of the gear 22. A pawl 24 is tightly fitted to the right side of the ratchet 23. The pawl 24 is rotatably connected to the sliding block 13. The front side of the pawl 24 passes through and extends to the front side of the sliding block 13. A tension spring 25 is fixedly connected to the right side of the pawl 24. The right end of the tension spring 25 is fixedly connected to the inner wall of the sliding block 13.

[0021] Specifically, by pushing the sliding block 13 to slide within the second slide groove 11, while the gear 22 rotates on the rack 12, the ratchet 23 at the top rotates. Since the pawl 24 is tightly engaged with the ratchet 23 under the action of the tension spring 25, the ratchet 23 and the gear 22 can only rotate in one direction, thus fixing templates of different sizes. When it is necessary to unlock it, the pawl 24 is moved to stretch the tension spring 25. At this time, the pawl 24 and the ratchet 23 separate, and the ratchet 23 and the gear 22 can rotate in opposite directions, thereby pulling out the sliding block 13.

[0022] Reference Figure 3 The gear 22 is meshed with a rack 12 on its left side, and the rack 12 is fixedly connected to the fixing plate 9.

[0023] Specifically, the rack 12 and the gear 22 are meshed together, so that the gear 22 rotates on the right side of the rack 12 when the sliding block 13 moves.

[0024] Reference Figure 1 The top of each sliding block 13 is fixedly connected to a pointer 14, and the left side of each fixed plate 9 is provided with scale lines 10.

[0025] Specifically, when the sliding block 13 moves, it causes the pointer 14 at the top to move as well, so that the distance the sliding block 13 moves can be observed through the pointer 14 and the scale line 10, thereby obtaining the size of the mold.

[0026] Reference Figure 1 The right side of the sliding block 13 is fixedly connected to the limit plate 15.

[0027] Specifically, the limiting plate 15 is used to block the mold, thereby fixing the mold.

[0028] Reference Figure 1 The front and right sides of the connecting frame 3 are fixedly connected to the first motor 4, and the output ends of the two first motors 4 are fixedly provided with threaded rods 5.

[0029] Specifically, the two first motors 4 can drive the two threaded rods 5 to rotate respectively.

[0030] Reference Figure 1 The two threaded rods 5 are rotatably connected to the connecting frame 3 at one adjacent end, and the two threaded rods 5 are threadedly connected to the adjacent moving parts 6.

[0031] Specifically, the rotation of two threaded rods 5 drives the movement of two moving parts 6, thereby enabling the moving block 8 to move at any position.

[0032] Reference Figure 1 The two fixed components are mirrored on the diagonal of the base plate 1.

[0033] Specifically, by setting fixed components on two mirrors, the length and width of the mold can be measured simultaneously, and the mold can be fixed at the same time.

[0034] Working principle: When in use, the mold is placed on the base plate 1, close to the two fixed plates 9, and the sliding block 13 is pushed to slide in the second slide groove 11. At the same time, the gear 22 rotates on the rack 12, thereby driving the ratchet 23 at the top to rotate. Since the pawl 24 is tightly engaged with the ratchet 23 under the action of the tension spring 25, the ratchet 23 and the gear 22 can only rotate in one direction. The sliding block 13 drives the limiting plate 15 to move, thereby fixing the mold of different sizes. At the same time, the length and width of the mold are measured by the pointer 14 and the scale line 10. When it needs to be unlocked, the pawl 24 is moved to stretch the tension spring 25. At this time, the pawl 24 is separated from the ratchet 23. At this time, the ratchet 23 and the gear 22 can rotate in opposite directions, thereby pulling out the sliding block 13. At the same time, the three cylinders 2 drive the connecting frame 3 at the top to rise and fall, and the two first motors 4 drive the threaded rod 5 to rotate, thereby driving the two moving parts 6 to move, so that the moving block 8 moves in the first slide groove 7 at the top of the two moving parts 6. Simultaneously, the second motor 16 on the left drives the rotating component 18 to rotate, and the second motor 16 on the right drives the worm gear 17 to rotate, thereby driving the worm wheel 19 and the rotating component 20 to rotate, which in turn drives the measuring head 21 to rotate at any angle, thus realizing the measurement of the template from various angles.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
