[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0023] Please refer to Figures 1-4 , an embodiment provided by the present utility model: an adjustable positioning seat structure for an SMC compression mold, including a positioning seat 1. On both sides of the middle part inside the positioning seat 1, limiting chutes 101 are provided.

At the front and rear ends of the middle part inside the positioning seat 1, transmission slots 105 are provided. Between the middle parts of the two transmission slots 105, a second rotating shaft 4 is jointly provided. At the front and rear ends of the middle part of the upper end surface of the positioning seat 1, positioning rods 5 are fixedly connected. In the middle of the positioning rod 5, a screw rod 501 is provided. At the middle part of the upper end of the positioning seat 1, a mold 6 is connected. In the middle of the two side end faces of the mold 6, rectangular limiting grooves 601 are provided. At the front and rear ends of the middle part of the lower end surface of the mold 6, circular limiting grooves 602 are provided. In the middle of the circular limiting groove 602, a fixing ring 603 is fixedly connected. At the upper end inside the circular limiting groove 602, a spring 604 is provided. The lower end of the spring 604 is fixedly connected with an annular internal thread connecting piece 605.

[0024] Furthermore, on both sides of the middle part of the first rotating shaft 2, threaded portions 201 are respectively arranged inside the two limiting chutes 101, and the two threaded portions 201 are arranged in a mirror image.

[0025] Furthermore, on one side of the middle part inside the positioning seat 1, a first motor slot 103 is provided. Inside the first motor slot 103, a first servo motor 104 is provided. One end of the first rotating shaft 2 extends into the first motor slot 103 and is fixedly connected with the output shaft of the first servo motor 104. The first rotating shaft 2 is driven to rotate by the first servo motor 104.

[0026] Further, threaded sliders 302 are fixedly connected to the lower ends of both jigs 3. The two threaded sliders 302 slide into the two limit chute 101 respectively. The two threaded portions 201 on the first rotating shaft 2 pass through the middle parts of the two threaded sliders 302 and are threadedly connected to the threaded sliders 302. By rotating the first rotating shaft 2, the two threaded sliders 302 are driven to move relatively, and then the two jigs 3 move relatively on the upper end of the positioning seat 1, realizing the clamping of both sides of the mold 6.

[0027] Further, the rectangular limit portion 301 on the jig 3 is inserted into the rectangular limit groove 601 on the mold 6. The two positioning rods 5 are respectively inserted into the two circular limit grooves 602 on the lower end surface of the mold 6 and extend to the lower end of the fixed ring 603. When the two jigs 3 clamp both sides of the mold 6, the mold 6 is limited by inserting the two rectangular limit portions 301 into the rectangular limit groove 601 on the mold 6. At the same time, by adjusting the two jigs 3, the clamping of molds 6 with different sizes can be realized.

[0028] Further, the upper end of the screw rod 501 passes through the middle part of the fixed ring 603 and is threadedly connected to the middle part of the annular internal thread connecting piece 605. The lower ends of the two screw rods 501 respectively extend into the two transmission grooves 105 and are fixedly connected with second conical teeth 502. The second rotating shaft 4 is fixedly connected with first conical teeth 401 in the two transmission grooves 105 respectively. The first conical teeth 401 are meshed with the tooth parts of the second conical teeth 502. By driving the second rotating shaft 4 to rotate, the two screw rods 501 are driven to rotate at the same time. When the mold 6 is placed on the positioning seat 1, the two positioning rods 5 are respectively inserted into the two circular limit grooves 602 on the lower end surface of the mold 6. The upper end of the screw rod 501 passes through the middle part of the fixed ring 603 and jacks up the middle part of the annular internal thread connecting piece 605, compressing the spring 604. When the second rotating shaft 4 drives the screw rod 501 to rotate, the spring 604 is fixedly connected with the annular internal thread connecting piece 605 to prevent rotation, and the middle part of the lower end of the annular internal thread connecting piece 605 is pushed to sleeved on the upper end of the screw rod 501 and is threadedly connected with the screw rod 501. When the screw rod 501 continues to rotate, it will pull the annular internal thread connecting piece 605 to descend and press down the fixed ring 603, so that the two annular internal thread connecting pieces 605 press down the two fixed rings 603 at the same time, and then the mold 6 and the positioning seat 1 are pressed tightly to prevent shaking.

[0029] Further, a second motor slot 106 is provided at the front end of the middle part inside the positioning seat 1. A second servo motor 107 is arranged inside the second motor slot 106. The front end of the second rotating shaft 4 extends into the second motor slot 106 and is fixedly connected with the output shaft of the second servo motor 107. The second rotating shaft 4 is driven to rotate by the second servo motor 107.

[0030] Working principle: When in use, place the mold 6 at the middle of the upper end of the positioning seat 1, insert the two positioning rods 5 into the two circular limiting grooves 602 on the lower end surface of the mold 6 respectively. The upper end of the screw rod 501 passes through the middle of the fixing ring 603 to jack up the middle of the annular internal thread connecting piece 605, compressing the spring 604. When the second servo motor 107 drives the second rotating shaft 4 to rotate, and the second rotating shaft 4 drives the screw rod 501 to rotate, the spring 604 is fixedly connected to the annular internal thread connecting piece 605 to prevent rotation, and the middle of the lower end of the annular internal thread connecting piece 605 is pushed to sleeve onto the upper end of the screw rod 501 and is threadedly connected to the screw rod 501. When the screw rod 501 continues to rotate, it will pull the annular internal thread connecting piece 605 downwards and press down the fixing ring 603, so that the two annular internal thread connecting pieces 605 simultaneously press down the two fixing rings 603, thereby pressing the mold 6 and the positioning seat 1 tightly to prevent shaking. The first servo motor 104 drives the first rotating shaft 2 to rotate, and the rotation of the first rotating shaft 2 drives the two threaded sliders 302 to move relatively, so that the two clamps 3 move relatively on the upper end of the positioning seat 1 to realize the clamping of both sides of the mold 6. After the two clamps 3 clamp both sides of the mold 6, the two rectangular limiting parts 301 are inserted into the rectangular limiting grooves 601 on the mold 6 to limit the mold 6. At the same time, by adjusting the two clamps 3, the clamping of molds 6 of different sizes can be realized.
