DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0022] Refer to Figures 1 - 4, A product contour acquisition device for industrial design, including a support platform 1. The support platform 1 is provided with a first cavity and a second cavity. A stepping motor is fixedly connected inside the first cavity. The driving end of the stepping motor penetrates through the support platform 1 and is fixedly connected with a rotating column 6. The top of the rotating column 6 is fixedly connected with a support column 9. The outer side wall of the support column 9 is fixedly connected with a first support plate 11 and a second support plate 16. The top of the first support plate 11 is fixedly connected with an electric telescopic rod 10. The driving end of the electric telescopic rod 10 penetrates through the first support plate 11 and is fixedly connected with a fixed cylinder 12. A second spring 30 is fixedly connected to the inner side wall of the fixed cylinder 12. A first sliding hole is provided at the bottom of the fixed cylinder 12. A telescopic rod 14 is slidably connected inside the first sliding hole. The top of the telescopic rod 14 is fixedly connected with a stopper 29. The second spring 30 is fixedly connected to the top of the stopper 29. The bottom of the telescopic rod 14 is fixedly connected with a pressing plate 13. The pressing plate 13 is provided with a second sliding hole. The bottom of the first support plate 11 is fixedly connected with a limiting rod 15 passing through the second sliding hole. The outer side wall of the limiting rod 15 is slidably connected with the inner side wall of the second sliding hole. The second support plate 16 is provided with a first opening. The top of the second support plate 16 is fixedly connected with a normal motor 17. The driving end of the normal motor 17 is fixedly connected with a first movable rod 18. The end of the first movable rod 18 is rotatably connected with a second movable rod 19. A connecting column 21 is slidably connected to the inner side wall of the first opening. The top of the connecting column 21 is fixedly connected with a baffle 20. The end of the second movable rod 19 is rotatably connected with the outer side wall of the baffle 20. The bottom of the connecting column 21 is fixedly connected with a sensor 22. The top of the support platform 1 is fixedly connected with a sand frame 5. Molding sand 7 is placed inside the sand frame 5. The length and width of the inner side wall of the sand frame 5 are larger than the length and width of the pressing plate 13. The sand frame 5 is located directly below the sensor 22. A first sphere 25 is located directly above the right side wall of the transmission rod 23. The first sphere 25 and the second sphere 26 are made of steel. The first support plate 11 and the second support plate 16 are at a right angle on the outer side wall of the support column 9. A damping liquid is applied at the connection between the limiting rod 15 and the pressing plate 13. The bottom of the baffle 20 is in contact with the top of the second support plate 16. When the second spring 30 contracts and resets, the damping liquid can effectively reduce the vibration of the second spring 30. The baffle 20 can ensure that the connecting column 21 will not fall off from the first opening. When the connecting column 21 moves, the baffle 20 can ensure the stability of the connecting column 21 during movement, thereby ensuring the stability of the pressing plate 13. By rotating the first movable rod 18 through the normal motor 17, the second movable rod 19 moves vertically left and right reciprocally along the first opening under the influence of the first movable rod 18, and synchronously drives the connecting column 21 and the sensor 22 to move. When the product is placed on the molding sand 7, the sensor 22 will perform a three-dimensional scan of the product over a large range, and then transmit the data to the contour data processor 27. Then, the first support plate 11 is rotated to directly above the sand frame 5 through the stepping motor. Subsequently, the fixed cylinder 12 is driven to move vertically downward through the electric telescopic rod 10. At this time, the telescopic rod 14 and the pressing plate 13 also move downward. When the pressing plate 13 contacts the product, the product will be pressed into the molding sand 7.When pressed to the limit, the pressing plate 13 will drive the telescopic rod 14 to move upward along the fixed cylinder 12, and compress the second spring 30. At this time, the pressing operation is completed, and then the fixed cylinder 12 can be moved upward to reset by retracting the driving end of the electric telescopic rod 10.

[0023] The bottom of the sand frame 5 communicates with the second cavity. The support table 1 is provided with a second opening communicating with the second cavity. The inner side wall of the second opening is fixedly connected with a rotating rod 28. A pressing rod 4 is slidably sleeved on the outer side wall of the rotating rod 28. The right side wall of the pressing rod 4 extends outside the support table 1 through the second opening. The left side wall of the pressing rod 4 is fixedly connected with a first sphere 25. The inner side wall of the second cavity is rotatably connected with a transmission rod 23. A second sphere 26 is fixedly connected to the outer side wall of the transmission rod 23. A first spring 24 is fixedly connected to the bottom of the transmission rod 23. The first spring 24 is fixedly connected with the inner side wall of the second cavity. A plurality of legs 2 are fixedly connected to the bottom of the support table 1. A scraping plate 8 is slidably connected to the inner side wall of the sand frame 5. A handle 3 is fixedly connected to the top of the scraping plate 8. A contour data processor 27 is fixedly connected to the outer side wall of the support column 9. The contour data processor 27 is electrically connected to the sensor 22. The plurality of legs 2 are uniformly arranged at the four corners of the bottom of the support table 1. The handle 3 is L-shaped. The bottom of the scraping plate 8 is in contact with the plastic mold sand 7. After the product is taken out of the plastic mold sand 7 and the data is recorded, the operator presses the pressing rod 4 to move the first sphere 25 upward. After the operator releases the hand, the first sphere 25 will move downward due to gravity and contact the transmission rod 23 to make it rotate. When the transmission rod 23 rotates towards the pressing rod 4, the second sphere 26 will contact the bottom of the sand frame 5, thereby generating vibration to make the plastic mold sand 7 evenly cover the sand frame 5 again. At this time, the first spring 24 will stretch and contract up and down, and drive the second sphere 26 to hit the bottom of the sand frame 5 several times, thereby accelerating the plastic mold sand 7 to return to a flat state. When the first spring 24 is stable, the operator can hold the handle 3 and slide the scraping plate 8 along the inner side wall of the sand frame 5, so as to make the plastic mold sand 7 more flat, thus not affecting the next acquisition operation.

[0024] The working principle of the present invention:

[0025] The movable rod 18 is rotated by the normal motor 17. Affected by the movable rod 18, the movable rod 19 makes a vertical reciprocating movement left and right along the opening 1, and synchronously drives the connecting column 21 and the sensor 22 to move. When the product is placed on the molding sand 7, the sensor 22 will perform a three-dimensional scan of the product in a large range, and then transmit the data to the contour data processor 27. Then, the support plate 11 is rotated to directly above the sand box 5 by the stepping motor. Subsequently, the fixed cylinder 12 is driven to move vertically downward by the electric telescopic rod 10. At this time, the telescopic rod 14 and the pressing plate 13 also move downward. When the pressing plate 13 contacts the product, the product will be pressed into the molding sand 7. When pressed to the limit, the pressing plate 13 will drive the telescopic rod 14 to move upward along the fixed cylinder 12, and the second spring 30 will be in a compressed state. At this time, the pressing operation is completed. Then, the driving end of the electric telescopic rod 10 is retracted to move the fixed cylinder 12 upward to reset it;

[0026] After the product is taken out from the molding sand 7 and the data is recorded, the operator presses the push rod 4 to move the first ball 25 upward. After the operator releases the hand, the first ball 25 will move downward due to gravity and contact the transmission rod 23 to make it rotate. When the transmission rod 23 rotates towards the push rod 4, the second ball 26 will contact the bottom of the sand box 5, thereby generating vibration to make the molding sand 7 evenly cover the sand box 5 again. At this time, the first spring 24 will stretch and contract up and down, and drive the second ball 26 to impact the bottom of the sand box 5 several times, so as to accelerate the molding sand 7 to return to a flat state. When the first spring 24 is stable, the operator can hold the handle 3 and slide the scraper 8 along the inner wall of the sand box 5, so that the molding sand 7 can be made more flat, thus not affecting the next acquisition operation.

[0027] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
