Technical Field

[0001] This utility model relates to the technical field of dimensional measuring devices, specifically a dimensional measuring device for plastic mold production. Background Technology

[0002] Plastic molds are tools used in the plastics processing industry, working in conjunction with plastic molding machines to give plastic products their complete shape and precise dimensions. During production, to meet requirements, the dimensions of the produced plastic molds need to be measured and inspected; therefore, appropriate dimensional measuring devices are required.

[0003] However, current dimensional measuring devices used in plastic mold production are inconvenient to operate and use because some molds are large and difficult to move. To address these issues, a new dimensional measuring device for plastic mold production is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a dimensional measuring device for plastic mold production, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A dimensional measuring device for plastic mold production includes a base plate, a lifting platform on the top of the base plate, a lifting mechanism between the lifting platform and the base plate, a vertical rod fixedly installed on one side of the top of the base plate, the vertical rod passing through the lifting platform and slidably connected to the lifting platform, a top plate fixedly installed above the lifting platform at the top of the vertical rod, a sliding sleeve slidably fitted on the top plate, a first locking bolt threaded through the top of the sliding sleeve, a retaining sleeve rotatably connected to the bottom of the sliding sleeve, a hand-tightening bolt provided on the retaining sleeve, a main measuring scale slidably connected inside the retaining sleeve, a fixed measuring mechanism fixedly installed at one end of the bottom of the main measuring scale, and a movable measuring mechanism slidably fitted on the main measuring scale.

[0007] As a further embodiment of this utility model: both the fixed measuring mechanism and the moving measuring mechanism include vertical bars, and the vertical bars in the fixed measuring mechanism and the moving measuring mechanism are symmetrically arranged. The vertical bar of the fixed measuring mechanism is fixedly connected to the bottom of the main measuring ruler, and a vernier scale is fixedly installed on the top of the vertical bar of the moving measuring mechanism. The vernier scale is slidably sleeved on the main measuring ruler, and a third locking bolt is provided at the bottom of the vernier scale. A slot is opened on the opposite side of the vertical bar, and a locking strip is slidably connected in the slot. A horizontal plate is fixedly connected to the bottom end of the locking strip, and a second locking bolt is provided at the bottom end of the other side of the locking strip.

[0008] As a further improvement of this utility model: the opposite side of the card strip is flush with the same side of the vertical strip and the horizontal plate.

[0009] As a further improvement of this utility model, a limiting plate is fixedly installed at the end of the top plate.

[0010] As a further improvement of this utility model: the base plate is fixedly mounted with legs at the four corners, and the bottom of the legs is fixedly mounted with casters.

[0011] As a further improvement of this utility model, the universal wheel is equipped with a self-locking mechanism.

[0012] As a further embodiment of this utility model: the lifting mechanism includes two X-shaped brackets, which are symmetrically arranged between the base plate and the lifting platform. The two ends of one side of the X-shaped bracket are rotatably connected to the corresponding base plate and the lifting platform. The top of the other side of the X-shaped bracket is rotatably connected to a second cross brace, and the bottom of the other side of the X-shaped bracket is rotatably connected to a first cross brace. The two ends of the first cross brace and the second cross brace are slidably connected to guide grooves, which are fixedly installed on the corresponding base plate and the lifting platform. A lead screw is threaded through the first cross brace and rotatably connected to the side wall of the vertical rod and the top of the base plate. A handle is fixedly connected to the end of the lead screw away from the vertical rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model allows for easy adjustment of the orientation of the main measuring scale by rotating the ferrule and by sliding the sliding sleeve. The first locking bolt is used to fix the sliding sleeve. During measurement, the main measuring scale is slid to make the fixed measuring mechanism fit with the mold, and the moving measuring mechanism is slid to make it fit with the other side of the mold, thus achieving the measurement of the mold. Repeating the above steps allows for easy measurement of the dimensions of the mold in another direction. This achieves the goal of measuring the mold without moving it or holding the measuring mechanism by hand, making it convenient to use.

[0015] 2. This utility model uses a handle to drive a lead screw to rotate. The rotating lead screw drives the first cross brace to move under the guidance of the guide groove, which in turn drives the X-shaped bracket, causing the lifting platform to lift the mold to be measured. By adjusting the length of the clip extending from the slot in the vertical bar, the clip moves the horizontal plate. After adjustment, the clip is locked and fixed by rotating the second locking bolt, thus realizing the adjustment of the length of the fixed measuring mechanism and the moving measuring mechanism to meet the measurement of molds of different thicknesses.

[0016] 3. This utility model uses a handle to drive the lead screw to rotate. The rotating lead screw drives the first cross brace to move under the guidance of the guide groove, which in turn drives the X-shaped bracket, so that the lifting platform is at its lowest point, making it convenient to place the mold to be measured on the lifting platform.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 In this embodiment of the present invention, a size measuring device for plastic mold production includes a base plate 1. A lifting platform 7 is provided on the top of the base plate 1. A lifting mechanism is provided between the lifting platform 7 and the base plate 1. A vertical rod 9 is fixedly installed on one side of the top of the base plate 1. The vertical rod 9 passes through the lifting platform 7 and is slidably connected to the lifting platform 7. A top plate 10 is fixedly installed above the lifting platform 7 at the top of the vertical rod 9. A sliding sleeve 11 is slidably sleeved on the top plate 10. A first locking bolt 12 is threadedly connected through the top of the sliding sleeve 11. A retaining sleeve 14 is rotatably connected to the bottom of the sliding sleeve 11. A hand-tightening bolt is provided on the retaining sleeve 14. A main measuring ruler 15 is slidably connected inside the retaining sleeve 14. A fixed measuring mechanism 16 is fixedly installed at one end of the bottom of the main measuring ruler 15. A moving measuring mechanism 17 is slidably sleeved on the main measuring ruler 15.

[0024] In use, the lifting platform 7 is adjusted to its lowest point using the lifting mechanism, making it easy to place the plastic mold product to be measured on the lifting platform 7. By rotating the clasp 14, the orientation of the main measuring scale 15 is adjusted. The lifting platform 7 is then driven to rise by the lifting mechanism, so that the mold is positioned between the fixed measuring mechanism 16 and the moving measuring mechanism 17. The sliding sleeve 11 is slid to adjust the position of the mold, while the main measuring scale 15 is slid to make the fixed measuring mechanism 16 fit with the mold. The first locking bolt 12 on the sliding sleeve 11 and the hand-tightening bolt on the clasp 14 are locked. The moving measuring mechanism 17 is then slid to fit with the mold, thus achieving the measurement of the mold. When measuring the mold in another direction, the above steps are repeated for ease of use.

[0025] Both the fixed measuring mechanism 16 and the moving measuring mechanism 17 include vertical bars 18, and the vertical bars 18 in the fixed measuring mechanism 16 and the moving measuring mechanism 17 are symmetrically arranged. The vertical bar 18 of the fixed measuring mechanism 16 is fixedly connected to the bottom of the main measuring scale 15. A vernier scale 23 is fixedly installed on the top of the vertical bar 18 of the moving measuring mechanism 17. The vernier scale 23 is slidably sleeved on the main measuring scale 15. A third locking bolt 24 is provided at the bottom of the vernier scale 23. A slot 19 is opened on the opposite side of the vertical bar 18. A locking strip 20 is slidably connected in the slot 19. A horizontal plate 21 is fixedly connected to the bottom of the locking strip 20. The other side of the locking strip 20 is... The end is provided with a second locking bolt 22. By adjusting the length of the clip 20 extending from the slot 19 of the vertical bar 18, the clip 20 moves with the horizontal plate 21. After adjustment, the clip 20 is locked and fixed by rotating the second locking bolt 22, thereby adjusting the length of the fixed measuring mechanism 16 and the moving measuring mechanism 17. The distance between the fixed measuring mechanism 16 and the moving measuring mechanism 17 is adjusted by moving the vernier scale 23 of the moving measuring mechanism 17. When the horizontal plate 21 in the fixed measuring mechanism 16 and the moving measuring mechanism 17 is in contact with the object to be measured, the third locking bolt 24 on the vernier scale 23 is locked.

[0026] The card strip 20 is flush with the vertical strip 18 and the horizontal plate 21 on the opposite side.

[0027] A limiting plate 13 is fixedly installed at the end of the top plate 10 to prevent the sliding sleeve 11 from detaching from the main measuring ruler 15 from the top plate 10.

[0028] The base plate 1 is fixedly mounted with four legs 2 at its four corners. The bottom of the legs 2 is fixedly mounted with casters 3. The casters 3 are equipped with a self-locking mechanism. By setting the casters 3 on the legs 2, the movement of the device is facilitated. The self-locking mechanism on the casters 3 fixes the casters 3 in place, preventing the device from moving during use.

One end of each X-shaped bracket 4 is rotatably connected to the corresponding base plate 1 and lifting platform 7. The top of the other side of each X-shaped bracket 4 is rotatably connected to a second cross brace 26, and the bottom of the other side of each X-shaped bracket 4 is rotatably connected to a first cross brace 25. The first cross brace 25 and the second cross brace 26 are slidably connected to guide grooves 8, which are fixedly installed on the corresponding base plate 1 and lifting platform 7. A threaded rod 5 is threaded through the first cross brace 25. The rod 5 is rotatably connected to the side wall of the vertical rod 9 and the top of the base plate 1. A handle 6 is fixedly connected to the end of the rod 5 away from the vertical rod 9. In use, the handle 6 drives the rod 5 to rotate. The rotating rod 5 drives the first cross brace 25 to move under the guidance of the guide groove 8, thereby driving the X-shaped brackets 4 and adjusting the height of the lifting platform 7.
