Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1 to 6 As shown, a combined mold blank includes a base 1, a rubber pad 2 is fixedly connected to the upper side of the base 1, and a mold base 3 is placed on the upper side of the rubber pad 2. The rubber pad 2 can also increase the friction with the bottom of the mold base 3, making the mold base 3 less prone to shaking and more stable. The base 1 has an array of sliding rods 4 connected inside, and two symmetrically arranged clamping slide plates 5 are slidably connected to the outer surface of the sliding rods 4. Rubber strips 6 are evenly connected to one side of the two clamping slide plates 5. Round rods 11 are evenly connected inside the two clamping slide plates 5, and clamping blocks 12 are slidably connected to the outer surface of the round rods 11.

[0026] A spring 13 is fixedly connected between the clamping block 12 and the clamping slide plate 5. Rubber strips 14 are arrayed on one side of the clamping block 12. The rubber strips have a large coefficient of friction. By contacting the surface of the mold base 3, they can increase the friction between the mold base 3 and the positioning mechanism, resulting in good stability. An L-shaped support plate 7 is fixedly connected to the bottom inside the base 1. A rotating shaft seat 8 is rotatably connected between the L-shaped support plate 7 and the base 1. A connecting rotating plate 10 is rotatably connected inside both the clamping slide plates 5 and the rotating shaft seat 8. A servo motor 9 is fixedly connected to one side of the L-shaped support plate 7. The servo motor 9 is model SMBL-60P. The positioning mechanism composed of the clamping slide plate 5 and the clamping block 12 can quickly and accurately fix the mold base 3 in the processing area.

[0027] The output shaft of the servo motor 9 is fastened to the rotating shaft seat 8. The upper sides of the two clamping slides 5 are fixedly connected to side plates 15. One side of each side plate 15 is threaded with a bolt 16. The lower side of the bolt 16 passes through the side plate 15 and extends to the other side of the side plate 15. The lower side of each bolt 16 is fixedly connected to a disc 17. By using the bolt 16 and the disc 17, rotating the bolt 16 can drive the disc 17 to move, so that the disc 17 fits against the upper part of the mold base 3 for further positioning of the mold base 3.

[0028] The upper side of the mold base 3 is provided with an embedding groove 18, and the mold core 21 is snapped into the inside of the embedding groove 18. The upper side of the mold base 3 is provided with an array of grooves 19, and the bottom of the grooves 19 is fixedly connected with a fixing post 20. Two locking blocks 22 are fixedly connected around the mold core 21.

[0029] One side of the locking block 22 is engaged inside the groove 19. A through mounting groove 28 is provided on one side of the locking block 22. One side of the fixing post 20 is engaged inside the mounting groove 28. Two symmetrically arranged snap-fit ​​slots 29 are provided on the upper side of the mold core 21. The two snap-fit ​​slots 29 can be used to apply force to the mold core 21 so as to remove the mold core 21 from the inside of the mold base 3.

[0030] Guide rods 23 are slidably connected to both ends inside the embedding groove 18. Round seats 24 are fixedly connected to one side of each guide rod 23. One side of the guide rod 23 passes through the mold base 3 and extends to one side of the mold base 3. Connecting plates 26 are fixedly connected to one side of each guide rod 23. Springs 25 are fixedly connected between each round seat 24 and the embedding groove 18. Through the two locking methods of the fixing post 20 locking the locking block 22 and the round seat 24 locking the mold core 21, flexible and convenient assembly is achieved, improving the efficiency of mold base assembly.

[0031] Both ends of the mold core 21 are provided with circular grooves 30, and one side of the circular seat 24 is snapped into the inside of the circular groove 30. The inside of the two connecting plates 26 are rotatably connected to two rotating plates 27.

[0032] The working principle of the combined mold base provided by this utility model is as follows:

[0033] By first placing the mold base 3 above the rubber base pad 2, the mold base 3 can squeeze the elastic clamping blocks 12, allowing the four clamping blocks 12 to clamp the front and rear sides of the mold base 3. Then, the servo motor 9 is started, and the output shaft of the servo motor 9 can drive the rotating shaft seat 8 to rotate. At this time, the rotating shaft seat 8 can also drive the two connecting rotating plates 10 to rotate and adjust, so as to pull the two clamping slide plates 5 on the slide rod 4 to move towards each other. In this way, the two clamping slide plates 5 can clamp the left and right sides of the mold base 3. In addition, the rubber strip 6 at the clamping slide plate 5 and the rubber strip 14 at the clamping block 12 can increase the friction of the mold base 3, which is used to stably and reliably position the mold base 3, making it less prone to shaking and displacement. The positioning mechanism formed by the clamping slide plates 5 and the clamping blocks 12 can quickly and accurately fix the mold base 3 in the processing area, improving the processing accuracy of the combined mold blank.

[0034] By pulling the connecting plate 26, the connecting plate 26 moves the guide rod 23, compressing the elastic round seat 24. Then, the rotating plate 27 is rotated to the side closer to the mold base 3, so that the rotating plate 27 can support and fix the contracted round seat 24. Next, the mold core 21 is snapped into the groove 19 of the mold base 3. At this time, the locking block 22 will also enter the interior of the groove 19. At this time, the fixing post 20 in the groove 19 can lock the mounting groove 28 of the locking block 22 to assist in guiding the installation of the mold core 21, so that the mold core 21 can accurately align with the mold base 3 to form a combined mold blank. This allows the combined mold blank to be assembled flexibly and conveniently. At the same time, the rotating plate 27 is rotated to a position away from the mold base 3, and the two elastic round seats 24 can automatically extend and snap into the two round grooves 30 of the mold core 21 to tightly lock the mold core 21. In this snapping method, different mold blanks can be combined conveniently, improving the efficiency of mold blank assembly.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
