[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 mold opening frame for a new energy vehicle mold blank includes a mold opening frame body 1 and a clamping mechanism. A lower mold 2 is placed at the bottom inside the mold opening frame body 1, and a hydraulic cylinder 6 is fixedly connected to the top inside the mold opening frame body 1. The hydraulic cylinder 6 is model HSG 80 / 60E-1100. A top plate 7 is fixedly connected to the lower side of the hydraulic cylinder 6, and an upper mold 3 is fixedly provided on the lower side of the top plate 7. Mounting blocks 4 are fixedly connected to both ends of the lower mold 2 and the upper mold 3. A slot 5 is provided on one side of the mounting block 4.

[0026] The clamping mechanism includes four clamping seats 15 located inside the mold frame body 1. One side of the clamping seat 15 is clamped into the inside of the clamping groove 5. A double-ended lead screw 8 is rotatably connected inside the top plate 7. Two lead screw sleeves 9 adapted to the double-ended lead screw 8 are provided on the double-ended lead screw 8. A crossbar 17 is fixedly connected inside the top plate 7. Two sliding plates 16 are slidably connected to the outer surface of the crossbar 17. The sliding plates 16 can drive the vertical plates 10 to move and adjust on the crossbar 17 so as to move with the lead screw sleeves 9 for loading and unloading. The two sliding plates 16 and the lower side of the lead screw sleeves 9 are all fixedly connected to the vertical plates 10. The four vertical plates 10 are all fixedly connected to the sliding rods 11. After the injection molding work is finished, the upper mold 3 can be raised and returned to its original position. At this time, the double-ended lead screw 8 is reversed. The two lead screw sleeves 9 on the double-ended lead screw 8 can drive the two sets of clamping seats 15 to move relative to each other and away from the mounting block 4. This is used to simultaneously release the limit on the lower mold 2 and the upper mold 3 so as to disassemble the upper and lower molds, which saves time and effort and is convenient to use.

[0027] The outer surfaces of the four slide bars 11 are slidably connected to sliders 12. A horizontal plate 13 is fixedly connected to one side of two sliders 12. One side of the horizontal plate 13 is fastened to the card seat 15. A horizontal plate 2 14 is fixedly connected between the two vertical plates 10. One side of the horizontal plate 2 14 is fastened to another card seat 15.

[0028] A limiting rod 28 is fixedly connected inside the top plate 7. The internal sliding of the lead screw sleeve 9 is placed on the limiting rod 28. The limiting rod 28 can limit and guide the movement trajectory of the two lead screw sleeves 9, allowing the two lead screw sleeves 9 to drive the two sets of clamping seats 15 to stably clamp the upper and lower molds. A servo motor 29 is fixedly connected to one side of the top plate 7. The model of the servo motor 29 is SMBL-60P. The output shaft of the servo motor 29 is fastened to the double-headed lead screw 8.

[0029] The bottom of the mold frame body 1 is connected to a vertical box 18. The upper side of the vertical box 18 has a groove 19 that matches the vertical plate 10. With the vertical box 18, the vertical plate 10 can slide up and down in the groove 19 of the vertical box 18 to guide the descent trajectory of the upper mold 3 and make the injection molding work stable. The bottom of the vertical box 18 is slidably connected to a guide rod 20. The upper side of the guide rod 20 is fixed to a top block 21. A first spring 22 is fixed between the top block 21 and the vertical box 18. The lower side of each of the four vertical plates 10 is fixed to a rubber round pad 24. The rubber round pad 24 at the vertical plate 10 also plays the role of buffering and protecting the mold. Rubber has good elasticity and buffering performance, which can further absorb and disperse pressure. Working together with the top block 21, it enhances the buffering effect. The lower side of each of the two horizontal plates 14 is fixed to a rubber pad 23.

[0030] A connecting plate 30 is fixed between the two vertical plates 10. The connecting plate 30 has a sliding connection between the array of guide rods 31. A circular seat 32 is fixed to the upper side of the guide rod 31, and a circular plate 34 is fixed to the lower side of the guide rod 31. A second spring 33 is fixed between the circular seat 32 and the connecting plate 30. At this time, the rubber pad 23 can also play the role of buffering and protecting the mold, buffering and protecting the elastic circular seat 32, allowing the circular seat 32 to buffer the pressure, reducing the impact force on the upper mold 3 and the entire mold, reducing the risk of the mold being damaged due to excessive pressure, and ensuring the stability and reliability of the mold frame for new energy vehicle mold blanks during long-term use.

[0031] Two symmetrically arranged fixing seats 25 are fixedly connected to the lower side of the top plate 7. Each fixing seat 25 has an installation groove 26 on one side. Two symmetrically arranged clamping plates 27 are fixedly connected to one side of the upper mold 3. One side of the clamping plate 27 is clamped and placed inside the installation groove 26.

[0032] The working principle of the mold frame for opening mold blanks for new energy vehicles provided by this utility model is as follows:

[0033] By placing the lower mold 2 into the bottom of the mold opening frame body 1, and then attaching the two clamping plates 27 of the upper mold 3 to the inside of the two fixed seats 25 for initial positioning of the upper mold 3, the servo motor 29 is then started, and the output shaft of the servo motor 29 drives the double-headed screw 8 to rotate. In this way, the two screw sleeves 9 on the double-headed screw 8 can move towards each other, so that the clamping seats 15 on the two horizontal plates 13 and 14 can be attached together to the slots 5 of the four mounting blocks 4, so as to lock the lower mold 2 and the upper mold 3 synchronously and securely, ensuring the stability of the mold during installation. This is conducive to the tight fit between the upper and lower molds and maintaining a stable state. The installation method does not require the use of bolts, reducing the labor intensity of loading and unloading, thereby realizing the rapid installation and disassembly of the upper and lower molds and improving the efficiency of loading and unloading of the mold opening frame for new energy vehicle blanks.

[0034] By activating the hydraulic cylinder 6, the upper mold 3 at the top plate 7 is moved downwards. This allows the upper mold 3 to fit and be positioned above the lower mold 2. Molten plastic is then injected into the mold, and after cooling and solidification, a molded product is obtained. As the upper mold 3 descends, the four vertical plates 10 can enter the grooves 19 of the four vertical boxes 18. At this time, the retainers 15 at the two horizontal plates 13 can move on the slide rod 11, so that the two retainers 15 can still clamp and fix the interior of the lower mold 2. Then, the four elastic top blocks 21 can buffer the pressure from the downward movement of the vertical plates 10. In conjunction with the rubber round pads 24 at the vertical plates 10, the mold is buffered and protected. Subsequently, the elastic round seat 32 will also buffer the pressure from the downward pressing of the upper mold 3. The double buffer structure can absorb and disperse the pressure, preventing the pressure from acting directly on the mold, better protecting the mold, extending the service life of the mold, and ensuring that the mold frame for new energy vehicle mold blanks can be used stably and reliably for a long time.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. 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. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
