[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 5 As shown, a modular plastic mold includes a workbench 1, a lower mold 2 placed on the upper side of the workbench 1, round rods 3 connected in an array inside the workbench 1, two first sliding plates 4 slidably connected to the outer surface of the round rods 3, clamping blocks 5 fixedly connected to one side of each of the two first sliding plates 4, and slots 6 opened on one side of each of the two clamping blocks 5, and two support plates 7 fixedly connected to the lower side of the workbench 1, with double-headed lead screws 8 rotatably connected inside the two support plates 7.

[0026] Two second slide plates 9 are installed on the outer surface of the double-ended lead screw 8 through the lead screw sleeve. A clamping block 10 is fixedly connected to one side of each of the two second slide plates 9. A slot 11 is opened on one side of each of the two clamping blocks 10. Rubber strips 12 are arrayed and connected to one side of each of the two first slide plates 4 and the second slide plates 9. By setting the rubber strips 12, the first slide plates 4 and the second slide plates 9 can increase the friction with the lower mold 2 so as to firmly clamp the lower mold 2. Positioning grooves 17 are opened around the lower mold 2. Insert pins 18 are fixedly connected inside the positioning grooves 17.

[0027] Both first slide plates 4 are rotatably connected to a rotating plate 13 inside. A U-shaped plate 14 is rotatably connected to one side of each rotating plate 13. A base plate 15 is fixedly connected to the lower side of the worktable 1. An electric push rod 16 is fixedly installed on one side of the base plate 15. The electric push rod 16 is model HB-DJ801. The output end of the electric push rod 16 is fastened to the U-shaped plate 14. A mounting bracket 20 is fixedly connected to the upper side of the worktable 1. A hydraulic cylinder 21 is fixedly connected to one side of the mounting bracket 20. The hydraulic cylinder 21 is model HSG 80 / 60E-1100. A connecting plate 22 is fixedly connected to the output end of the hydraulic cylinder 21. Two fixing blocks 25 are snapped into the inside of the connecting plate 22. An upper mold 23 is fixedly connected to the lower side of the two fixing blocks 25.

[0028] One side of clamping block 5 and clamping block 10 are engaged inside the positioning groove 17, and one side of the two inserts 18 are engaged inside the slot 6 and slot 11 respectively.

[0029] The lower mold 2 has an array of circular grooves 32. A telescopic seat 33 is slidably connected inside the circular grooves 32. A connecting spring 34 is fixedly connected between the telescopic seat 33 and the lower mold 2. A guide post 24 is arrayed on the lower side of the upper mold 23. The guide post 24 is located above the circular grooves 32. The lower side of the guide post 24 is slidably placed inside the circular grooves 32. When the hydraulic cylinder 21 drives the upper mold 23 to press down, the guide post 24 is precisely aligned with the circular grooves 32. With the help of the elastic telescopic seat 33, the pressure can be buffered, effectively reducing the impact and protecting the mold structure.

[0030] Two fixed blocks 25 have through grooves 26 inside. The upper side of the connecting plate 22 is rotatably connected to an array of rotating blocks 27. One side of the rotating blocks 27 is engaged inside the grooves 26. The upper side of the rotating blocks 27 is engaged with a first insertion rod 28. One side of the first insertion rod 28 passes through the rotating blocks 27 and extends to the upper side of the connecting plate 22. The upper side of the connecting plate 22 is fixedly connected to two symmetrically arranged side plates 29. One side of each side plate 29 is slidably engaged with a positioning plate 30. One side of the positioning plate 30 is engaged inside the grooves 26. The upper side of each positioning plate 30 is provided with a second insertion rod 31. One side of the second insertion rod 31 passes through the positioning plate 30 and extends to the upper side of the connecting plate 22.

[0031] A limiting rod 19 is fixedly connected between the two support plates 7. The interior of the second slide plate 9 is slidably placed on the limiting rod 19. The limiting rod 19 can limit and guide the movement trajectory of the two second slide plates 9, so that the two second slide plates 9 can move and adjust smoothly, so that the clamping work of the two first slide plates 4 can be carried out. A servo motor 88 is fixedly connected to one side of the support plate 7. The output shaft of the servo motor 88 is fastened to the double-headed lead screw 8. The interior of the second slide plate 9 is slidably placed on the round rod 3.

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

[0033] By placing the lower mold 2 onto the worktable 1 and then activating the electric push rod 16, the output end of the electric push rod 16 retracts, causing the U-shaped plate 14 to move downwards. This allows the two rotating plates 13 at the U-shaped plate 14 to rotate downwards, pulling the two first sliding plates 4 to move towards each other on the round rod 3. In this way, the two first sliding plates 4 can clamp onto the left and right sides of the lower mold 2. Subsequently, the clamping blocks 5 at the two first sliding plates 4 can be engaged into the positioning grooves 17 of the lower mold 2, and the inserts 18 in the positioning grooves 17 will also be engaged into the slots 6 of the clamping blocks 5 to lock the lower mold 2. Then, the servo motor 88 is activated. The output shaft of the servo motor 88 drives the double-ended lead screw 8 to rotate. At this time, the lead screw sleeve on the double-ended lead screw 8 can drive the two second slide plates 9 to move towards each other, so that the two second slide plates 9 can clamp onto the front and rear sides of the lower mold 2. The clamping blocks 10 at the two second slide plates 9 can clamp into the positioning groove 17 of the clamping blocks 10. Then the insert pins 18 in the positioning groove 17 will also clamp into the slots 11 of the clamping blocks 10. By using the mutual clamping of the clamping blocks and the insert pins 18, the lower mold 2 can be stably positioned around its perimeter. The splicing and assembly is time-saving and labor-saving, and there is no need to use bolts for installation, which reduces the labor intensity of assembly.

[0034] By inserting the two fixing blocks 25 at the upper mold 23 into the lower part of the connecting plate 22, the two fixing blocks 25 can penetrate the connecting plate 22 and extend to the upper part of the connecting plate 22. Then, rotate the four rotating blocks 27 respectively so that the four rotating blocks 27 can be respectively engaged in the grooves 26 of the two fixing blocks 25. Then, insert the first insertion rod 28 into the rotating blocks 27 and the connecting plate 22 to fix the four rotating blocks 27. Next, push the positioning plates 30 at the two side plates 29 so that the two positioning plates 30 are engaged in the grooves 26 of the two fixing blocks 25. Then, insert the two second insertion rods 31 into the positioning plates 3. The upper mold 23 is further secured by the connecting plate 22, preventing it from loosening. Then, the hydraulic cylinder 21 is activated, causing its output to move the upper mold 23 downwards and fit against the lower mold 2. At this point, the guide post 24 on the upper mold 23 can enter the circular groove 32. Molten plastic is then injected into the plastic mold, cooled, and fixed to form a plastic product. Meanwhile, the telescopic seat 33, equipped with a connecting spring 34, can buffer the pressure of the upper mold 23 and guide post 24 during movement, thus protecting the plastic mold and extending the service life of the modular plastic mold.

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.
