Description

Technical Field

[0001] The present invention belongs to the technical field of mold detection, and specifically relates to a mold precision detection device. Background Art

[0002] A mold is a tool used to make formed articles. This tool is composed of various parts. Different molds are composed of different parts. In addition to the mold itself, it also requires a mold base, a mold frame, a mold core, an ejector device for the workpiece, etc. These components are generally made into a general type.

[0003] After the mold is used in production and processing for a long time, it is necessary to detect the precision of the mold to avoid deviations in the manufactured products, which affect the quality or the assembly and use of many products. Therefore, the regular detection of mold precision is very important. The existing mold precision detection usually uses a three-coordinate measuring device to detect and measure the dimensional data of various aspects of the mold. However, the existing three-coordinate measuring devices generally do not have a fixture. Before measuring the mold, the operator needs to install the fixture according to the size of the mold. This method is very troublesome for continuous mold precision detection and requires the operator to frequently replace the fixture, which affects the detection efficiency. Therefore, it needs to be improved. Summary of the Invention

When the detection of the mold on the upper surface of the front placing table is completed, the pneumatic cylinder can be started, so that the movable block drives the toothed plate to move to the right, and thus the toothed plate drives the gear to rotate, so that the gear drives the movable shaft and the disc to rotate, and thus the two placing tables can be interchanged, and thus the detected mold can be quickly replaced, improving the detection efficiency.

[0017] 3. In the present invention, by providing an air pump, an air outlet hose, a rotating rod and a high-pressure nozzle, before detecting the mold, the operator can start the air pump, so that the air inlet pipe sucks in air, and then conveys it to the inside of the high-pressure nozzle through the air outlet hose and sprays it out from the high-pressure nozzle, so as to clean the dust on the outer surface of the mold and avoid the dust affecting the detection accuracy of the mold. The operator can start the driving motor, so that the round shaft drives the rotating rod to rotate, and thus the inner surface of the rotating rod squeezes and pushes the round block, so that the connecting block drives the mounting table to move, and the high-pressure nozzle can move, so as to clean the mold more comprehensively.

Specific embodiments

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Such as Figures 1 to 8As shown in the figure, an embodiment of the present invention provides a mold precision detection device, including a workbench 1. An activity shaft 2 is movably sleeved inside the workbench 1. A disc 3 is fixedly sleeved on the top surface of the activity shaft 2. Installation plates 4 are fixedly installed on both the front and rear sides of the upper surface of the disc 3.

A first motor 6 located on the right side of the installation plate 4 is fixedly installed on the outer surface of the side plate 5. The other end of the output shaft of the first motor 6 is fixedly connected to a double threaded rod 7. The left end of the double threaded rod 7 penetrates through the side plate 5 and is movably sleeved inside the side plate 5. Moving plates 8 are threadedly sleeved on both the left and right sides of the outer surface of the double threaded rod 7. The bottom of the moving plate 8 is movably connected to the top of the installation plate 4. A limiting frame 9 is fixedly installed on the top of the inner side of the moving plate 8. A connecting plate 10 is movably installed inside the limiting frame 9. A clamping plate 11 is fixedly installed on the top of the connecting plate 10. Round rods 12 are movably installed inside both the front and rear sides of the side plate 5. The outer surfaces of the round rods 12 are movably connected to the inner walls of the moving plate 8 and the connecting plate 10 respectively. A placement table 17 is fixedly installed on the top of the installation plate 4. The inner wall of the placement table 17 is movably sleeved on the outer surface of the double threaded rod 7.

[0029] The operator places the mold to be detected on the top of the placement table 17, and then starts the first motor 6, causing the double threaded rod 7 to rotate. Since the thread directions on the left and right sides of the outer surface of the double threaded rod 7 are opposite, the double threaded rod 7 can drive the two moving plates 8 to move towards each other, and further cause the clamping plates 11 to move towards each other, so as to clamp and fix the mold from the four corners of the mold, avoiding the mold shifting during the detection process and resulting in incorrect detection data.

[0030] Among them, a second motor 13 located on the left side of the installation plate 4 is fixedly installed on the outer surface of the side plate 5. The other end of the output shaft of the second motor 13 is fixedly connected to a rotating shaft 14. A rotating rod 15 is fixedly sleeved on the outer surface of the rotating shaft 14. Hinge rods 16 are hinged at both ends of the rotating rod 15. The other end of the hinge rod 16 is hinged to the left end of the round rod 12.

[0031] The operator can start the second motor 13, causing the rotating shaft 14 to drive the rotating rod 15 to rotate, so that the hinge rods 16 can drive the two round rods 12 to move towards each other, and further cause the clamping plates 11 to move towards each other, so as to clamp and fix molds of different lengths.

[0033] The operator starts the measuring machine 19, so that the probe 20 can detect the length, width, thickness and other data of the mold.

[0034] Among them, a gear 21 is fixedly sleeved on the outer surface of the movable shaft 2, and the outer surface of the gear 21 is movably connected to the top of the workbench 1.

[0035] When the gear 21 rotates, it will drive the movable shaft 2 to rotate, so that the disc 3 can rotate.

[0036] Among them, a pneumatic cylinder 22 is fixedly installed on the top of the workbench 1 at the rear side of the gear 21. The right end of the pneumatic cylinder 22 is fixedly connected to a movable block 23, and a toothed plate 24 is fixedly installed on the left side of the movable block 23. The outer surface of the toothed plate 24 meshes with the outer surface of the gear 21.

[0037] The operator starts the pneumatic cylinder 22, so that the pneumatic cylinder 22 drives the movable block 23 to move to the right, and further makes the toothed plate 24 move to the right, so that the toothed plate 24 drives the gear 21 to rotate.

[0038] Among them, a fixed plate 25 is fixedly installed on the front of the workbench 1. A pneumatic pump 26 is fixedly installed at the top on the right side of the fixed plate 25. An air inlet pipe 27 is fixedly installed at the bottom of the pneumatic pump 26, and an air outlet hose 28 is fixedly connected to the front of the pneumatic pump 26.

[0039] The operator starts the pneumatic pump 26, so that the air inlet pipe 27 can suck in air and then convey it through the air outlet hose 28.

[0040] Among them, a drive motor 29 is fixedly installed on the front of the fixed plate 25. The other end of the output shaft of the drive motor 29 is fixedly connected to a round shaft 30, and a rotating rod 31 is fixedly sleeved on the outer surface of the round shaft 30.

[0041] After the drive motor 29 is started, it will make the round shaft 30 drive the rotating rod 31 to rotate.

[0042] Among them, a slide rod 32 is fixedly sleeved inside the top of the fixed plate 25. An installation table 33 is movably sleeved on the outer surface of the slide rod 32.

A high-pressure nozzle 34 is fixedly installed inside the installation table 33, and the front end of the high-pressure nozzle 34 is fixedly connected to the left end of the air outlet hose 28.

[0043] By setting the high-pressure nozzle 34, the air is ejected through the high-pressure nozzle 34, so as to clean the outer surface of the mold.

[0044] Among them, a connecting block 35 is fixedly installed on the front of the installation table 33. The outer surface of the connecting block 35 is movably connected to the outer surface of the fixed plate 25. A round block 36 is fixedly installed on the front of the connecting block 35, and the outer surface of the round block 36 is movably connected to the inner surface of the rotating rod 31.

[0045] When the rotating rod 31 rotates, it will squeeze and push the round block 36, so that the connecting block 35 drives the mounting table 33 to move.

[0046] Working principle and usage process:

[0047] First, the operator places the mold to be detected on the upper surface of the placement table 17, and then starts the first motor 6, so that the double threaded rod 7 drives the two moving plates 8 to move towards each other. Furthermore, the moving plate 8 drives the clamping plate 11 to move towards each other through the limiting frame 9, so as to clamp and fix molds of different widths. Then the operator starts the second motor 13 again, so that the rotating shaft 14 drives the rotating rod 15 to rotate, and then the articulated rod 16 can pull the two round rods 12 to move towards each other, so that the round rods 12 drive the connecting plate 10 to move along the inside of the limiting frame 9, and then the connecting plate 10 drives the clamping plate 11 to move towards each other, so as to detect molds of different lengths, and then can clamp and fix molds of different lengths and widths, improving the flexibility of the device and avoiding the operator frequently replacing molds when detecting different molds.

[0048] After the mold is placed, the operator can start the air pump 26, so that the air inlet pipe 27 sucks in air, and then transports it into the high-pressure nozzle 34 through the air outlet hose 28 and sprays out from the high-pressure nozzle 34, so as to clean the dust on the outer surface of the mold and avoid the dust affecting the detection accuracy of the mold. The operator can start the drive motor 29, so that the round shaft 30 drives the rotating rod 31 to rotate, and then the inner surface of the rotating rod 31 squeezes and pushes the round block 36 to move, so that the round block 36 drives the mounting table 33 to move through the connecting block 35, and then the mounting table 33 can move left and right along the outer surface of the sliding rod 32, so that the high-pressure nozzle 34 can clean the mold more comprehensively.

[0049] Then the operator starts the measuring machine 19, so that the probe 20 can measure data such as the length, width and height of the mold, thus completing the detection of the mold accuracy. When detecting the mold on the upper surface of the placement table 17 in front of the disc 3, the operator can place the next mold to be detected on the upper surface of the placement table 17 behind the disc 3, and then after the detection is completed, start the air cylinder 22, so that the movable block 23 drives the toothed plate 24 to move to the right, and then the toothed plate 24 drives the gear 21 to rotate, so that the gear 21 drives the movable shaft 2 and the disc 3 to rotate, and then can swap the positions of the two placement tables 17, and then can quickly move the mold to be detected under the probe 20, facilitating the operator to disassemble the detected mold, reducing the overall standby time of the workbench 1 when the operator replaces the mold, and improving the detection efficiency.
