[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1-3 A mold frame for easy clamping includes a rectangular base 1 with a circular groove on the base 1. A hydraulic cylinder 2 is installed in the circular groove. A lifting plate 3 is fixedly connected to the top of the hydraulic cylinder 2. A first rectangular platform 4 is fixedly connected to the base 1. A second rectangular platform 5 is fixedly connected to the bottom of the lifting plate 3. A first clamping mechanism is provided on the first rectangular platform 4, and a second clamping mechanism is provided on the second rectangular platform 5. An injection port is provided on the lifting plate 3.

[0020] Specifically, the extension and retraction of the hydraulic cylinder 2 is controlled to bring the second rectangular platform 5 close to the first rectangular platform 4, thereby merging the two molds together for injection molding.

[0021] Furthermore, the first clamping mechanism includes a knob 6, a rotating rod 7, a first bevel gear 8, a first bidirectional screw 9, a second bevel gear, a first clamping plate 10, and a first limiting plate 11. One end of the rotating rod 7 is fixedly connected to the knob 6, and another end of the rotating rod 7 is fixedly connected to the first bevel gear 8. One end of the first bidirectional screw 9 is fixedly connected to the second bevel gear, and the second bevel gear meshes with the first bevel gear 8. The first bidirectional screw 9 is threadedly connected to the first clamping plate 10, and one side of the first clamping plate 10 is fixedly connected to the first limiting plate 11.

[0022] A rectangular opening is provided on one side of the first rectangular platform 4, and a rectangular shell is fixedly connected to one side of the first rectangular platform 4. The rotating rod 7 is rotatably connected to the rectangular shell. A first placement groove 17 is provided on the first rectangular platform 4, and the first clamping plate 10 is slidably connected to the first placement groove 17.

[0023] The lower mold is placed in the first placement groove 17, and then the knob 6 is turned to rotate the rotating rod 7. The rotating rod 7 drives the first bevel gear 8 to rotate, the first bevel gear 8 drives the second bevel gear to rotate, the second bevel gear drives the first bidirectional screw 9 to rotate, and the first bidirectional screw 9 drives the two first clamping plates 10 to move closer to each other, clamping the two sides of the lower mold. The first limiting plate 11 limits the lower mold to prevent it from sliding out of the first placement groove 17 during injection molding.

[0024] Furthermore, one end of the first bidirectional screw 9 is rotatably connected to the first placement groove 17, and a rectangular block 12 is fixedly connected inside the first placement groove 17. The first bidirectional screw 9 is rotatably connected to the rectangular block 12.

[0025] When the lower mold is placed into the placement slot, the lower mold is pushed until one side of the lower mold abuts against the rectangular block 12, so that the first limiting plate 11 can limit the lower mold.

[0026] Furthermore, the second clamping mechanism includes a drive motor 13, a second bidirectional screw 14, a second clamping plate 15, and a second limiting plate 16. The output end of the drive motor 13 is connected to the second bidirectional screw 14, the second bidirectional screw 14 is threadedly connected to the second clamping plate 15, and one side of the second clamping plate 15 is fixedly connected to the second limiting plate 16.

[0027] The drive motor 13 is installed on one side of the second rectangular platform 5. The second rectangular platform 5 has a second placement slot 18 and a sliding cavity. The second clamping plate 15 is slidably connected to the sliding cavity.

[0028] The drive motor 13 is powered by an external device and its opening and closing are controlled. The upper mold is placed in the second placement slot 18. Then the drive motor 13 drives the second bidirectional screw 14 to rotate. The second bidirectional screw 14 drives the two second clamping plates 15 on both sides to move closer to each other along the sliding cavity, clamping the two sides of the upper mold. The second limiting plate 16 limits the upper mold.

[0029] Meanwhile, the specific model and specifications of the drive motor 13 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be elaborated here.

[0030] The working principle of this utility model:

[0031] By placing the lower mold into the first placement slot 17, and then turning the knob 6, the rotating rod 7 is rotated. The rotating rod 7 drives the first bevel gear 8 to rotate, the first bevel gear 8 drives the second bevel gear to rotate, the second bevel gear drives the first bidirectional screw 9 to rotate, and the first bidirectional screw 9 drives the two first clamping plates 10 to move closer to each other, clamping the two sides of the lower mold. The first limiting plate 11 limits the lower mold.

[0032] The upper mold is placed in the second placement slot 18, and then the drive motor 13 drives the second bidirectional screw 14 to rotate. The second bidirectional screw 14 drives the two second clamping plates 15 on both sides to move closer to each other along the sliding cavity, clamping the two sides of the upper mold. The second limiting plate 16 limits the upper mold, making it easier to change different molds.
