[0003] After searching, a Chinese patent with publication number CN110370191A discloses a precision mold processing positioning device, which can flexibly adjust the positioning size of the positioning device, thereby improving its adaptability to precision molds of different sizes, thereby improving the versatility of the positioning device; including a workbench and four groups of legs, the left front side, left rear side, right front side and right rear side of the bottom end of the workbench are respectively connected to the top ends of the four groups of legs; also including a motor, two groups of fixed plates, two groups of limit slide rods, positive threaded rods, reverse threaded rods, two groups of clamping plates and a mounting assembly, the bottom end of the mounting assembly is mounted on the top end of the workbench, the bottom ends of the two groups of fixed plates are respectively mounted on the left and right sides of the top end of the mounting assembly, the left end of the left fixed plate is penetrated with an insertion hole, the right end of the motor is provided with a reducer, the right end of the reducer is connected to the left end of the left fixed plate, and the middle part of the left end of the right fixed plate is provided with a fixing groove;

[0004] In the above technology, although the positive thread rod and the reverse thread rod are driven by the motor to rotate, thereby driving the two sets of clamping plates to move, and then the mold is clamped and positioned, this method can only be used to position the mold in a certain direction (such as front and back or left and right), resulting in the mold being unable to be clamped and positioned by the positioning plates in the four directions of front, back, left and right synchronously during the placement process, resulting in the positioning accuracy being affected, and the requirement of high-precision processing cannot be met;

[0005] To this end, the utility model provides a mold processing positioning device. Utility Model Content

[0025] In this embodiment, when processing the mold, the operator needs to first place the mold on the placement table 2, and then turn on the motor 3. Driven by the motor 3, the rotating shaft 4 will rotate, thereby driving the first gear 5 and the second gear 8 to rotate synchronously. When the first gear 5 rotates, it will drive the two first racks 6 to move in the opposite direction synchronously, thereby driving the two first connecting arms 7 to move in the opposite direction synchronously. When the second gear 8 rotates, it will drive the two second racks 9 to move in the opposite direction synchronously, thereby driving the two second connecting arms 10 to move in the opposite direction synchronously. In the process of the two first connecting arms 7 and the two second connecting arms 10 moving, the four positioning plates 11 will be driven to approach the placement table 2 synchronously, thereby positioning and clamping the mold on the placement table 2. By clamping and positioning the mold synchronously in the four directions of front, back, left and right, the positioning accuracy of the mold can be greatly improved to meet the needs of high-precision processing. In this way, the operator only needs to place the mold on the placement table 2 to achieve rapid positioning without manual adjustment, thereby greatly improving the operating efficiency.

[0030] The driving box 1 is located above the second gear 8 and is fixedly connected to two second slide bars 14. The rotating shaft 4 is located between the two second slide bars 14. The second rack 9 is slidably connected to the second slide bars 14.

[0031] In this embodiment, the second rack 9 is slidably connected to the second slide rod 14 so that the second rack 9 is more stable during movement, and it can be ensured that the second rack 9 can always be meshed with the second gear 8.

[0032] The second connecting blocks 15 are fixedly connected to the top two ends of the second rack 9, and the second connecting blocks 15 are slidably connected to the second sliding rod 14;

[0033] In this embodiment, the second connecting blocks 15 are fixedly connected to the two ends of the top of the second rack 9, and the second connecting blocks 15 are slidably connected to the second slide rod 14. In this way, not only can the second rack 9 be smoothly slidably connected to the second slide rod 14, but both ends of the second rack 9 are also supported, so that the second rack 9 will not tilt, thereby ensuring the stability of the second rack 9 when moving, and allowing the second rack 9 to be stably meshed and connected with the second gear 8.

[0034] The first connecting arm 7 is fixedly connected to the first connecting block 13, and one end of the first connecting arm 7 located outside the driving box 1 is fixedly connected to the first supporting arm 16, the second connecting arm 10 is fixedly connected to the second connecting block 15, and one end of the second connecting arm 10 located outside the driving box 1 is fixedly connected to the second supporting arm 17, and the two first supporting arms 16 and the two second supporting arms 17 are fixedly connected to the four positioning plates 11 respectively;

[0035] In this embodiment, the first supporting arm 16 is designed to allow the first connecting arm 7 to be smoothly fixedly connected to the positioning plate 11, and the second supporting arm 17 is designed to allow the second connecting plate to be smoothly fixedly connected to the positioning plate 11, wherein the two first supporting arms 16 are respectively located at the front and rear ends of the driving box 1, and the two second supporting arms 17 are respectively located at the left and right ends of the driving box 1, so that the two first supporting arms 16 plus the two second supporting arms 17 can simultaneously drive the four positioning plates 11 to move.

[0040] Working principle: when processing the mold, the operator needs to place the mold on the placement table 2 first, and then turn on the motor 3. Under the drive of the motor 3, the rotating shaft 4 will rotate, thereby driving the first gear 5 and the second gear 8 to rotate synchronously. When the first gear 5 rotates, it will drive the two first racks 6 to move synchronously in the opposite direction. At this time, the two first connecting blocks 13 on the first rack 6 will slide on the first sliding rod 12, thereby ensuring the stability of the first rack 6 when moving. When the first rack 6 moves, it will drive the two first connecting arms 7 to move synchronously in the opposite direction, thereby driving the two first supporting arms 16 to move synchronously in the opposite direction. When the second gear 8 rotates, it will drive the two second racks 9 to move synchronously in the opposite direction. At this time, the two second racks 9 on the second rack 9 The connecting block 15 will slide on the second slide bar 14, thereby ensuring the stability of the second rack 9 when it moves. When the second rack 9 moves, it will drive the two second connecting arms 10 to move in the opposite direction synchronously, thereby driving the two second support arms 17 to move in the opposite direction synchronously. In the process of moving the two first support arms 16 and the two second support arms 17, the four positioning plates 11 will be driven to approach the placement table 2 synchronously, thereby positioning and clamping the mold on the placement table 2. By clamping and positioning the mold in the four directions of front, back, left and right synchronously, the positioning accuracy of the mold can be greatly improved to meet the needs of high-precision processing. In this way, the operator only needs to place the mold on the placement table 2 to achieve rapid positioning without manual adjustment, thereby greatly improving the operating efficiency.
