The column 2 can limit the bearing plate 2 4, thereby achieving the stability of the bearing plate 2 4 during longitudinal movement. The end of the column 2 away from the base 1 is fixedly connected with a bearing plate 1 3, and the bottom surface of the bearing plate 1 3 is fixedly installed with a hydraulic cylinder 5, and the telescopic end of the hydraulic cylinder 5 is fixedly connected with the upper surface of the bearing plate 2 4. A group of guide components 6 are provided on the outer side of the bearing plate 2 4, and the guide component 6 specifically includes a limit frame 601, the outer surface of the limit frame 601 is fixedly connected with the outer surface of the bearing plate 2 4, the material of the limit frame 601 is a magnet, and it can attract each other with the moving plate 703, so as to ensure that the outer surface of the moving plate 703 is always in contact with the guide wheel 603, and the inner rotation of the limit frame 601 is connected with a rotating shaft 1 602. The outer surface of the rotating shaft 1 602 is fixedly connected with a guide wheel 603, and the guide wheel 603 is located on the inner side of the limiting frame 601. The outer surface of the guide wheel 603 rotates with the outer surface of the moving plate 703. By providing the guide wheel 603, the moving plate 703 can be guided and the friction between the moving plate 703 can be reduced.

[0027] See also Figure 2 and Figure 6 As shown, a group of clamping mechanisms 7 are provided above the base 1. The clamping mechanism 7 specifically includes a fixed plate 701. The outer surface of the fixed plate 701 is fixedly connected to the upper surface of the base 1. A rotating rod 702 is rotatably connected inside the fixed plate 701. The outer surface of the rotating rod 702 is fixedly connected to a moving plate 703. The moving plate 703 is designed to be narrow at the bottom and wide at the top. The outer surface of the rotating rod 702 is made of magnets, which can attract each other with the limiting frame 601, so as to ensure that the outer surface of the moving plate 703 is always in contact with the guide wheel 603. A clamping plate 704 is fixedly connected to the end of the rotating rod 702 away from the fixed plate 701. A buffer plate 705 is fixedly connected to the outer surface of the clamping plate 704. A limiting groove 706 is provided inside the buffer plate 705. The buffer plate 705 is made of rubber. The outer surface has a large friction force, so it can increase the anti-slip property between the outer surface of the plastic product, thereby achieving the clamping effect on the plastic product.

[0028] In this embodiment, the guide wheel 603 contacts the moving plate 703 and drives the rotating shaft 1 602 to rotate. At this time, the moving plate 703 will drive the rotating rod 702, the clamping plate 704 and the buffer plate 705 to rotate. At the same time, the buffer plate 705 will gradually move closer to the plastic product. When the buffer plate 705 contacts the plastic product, the buffer plate 705 will gradually shrink in the direction of the clamping plate 704, thereby effectively protecting the plastic product body and preventing the outer surface from being damaged. The outer surface of the filling piece 12 is rotatably connected with the upper module 11, and the lower mold groove 9 is provided inside the base 1. The feed pipe 8 is inserted inside the base 1, and the feed pipe 8 is connected to the lower mold groove 9. When the upper module 11 and the filling piece 12 enter the lower mold groove 9, the raw material can be injected into the lower mold groove 9 through the feed pipe 8 through the external injection device. At this time, the required plastic product can be formed in the lower mold groove 9.

The motor 1002 is started by an external controller, and at this time, the motor 1002 will drive the second rotating shaft 1003 to reverse, and then drive the filling member 12 and the plastic product to rotate accordingly, and when the plastic product is clamped and limited by the buffer plate 705, the filling member 12 and the plastic product can be separated.

[0030] Working principle: When the utility model is in use, the hydraulic cylinder 5 is first controlled to move by an external controller. At this time, the telescopic end of the hydraulic cylinder 5 will push the carrier plate 2 4, the rotating mechanism 10, the upper module 11, the filling piece 12 and the guide assembly 6 to move downward. When the upper module 11 and the filling piece 12 enter the lower mold groove 9, the raw material can be injected into the lower mold groove 9 through the feed pipe 8 through the external injection device. At this time, the required plastic products can be formed in the lower mold groove 9. After the plastic products are cooled and formed, the hydraulic cylinder 5 can drive the carrier plate 2 4, the rotating mechanism 10, the upper module 11, the filling piece 12 and the guide assembly 6 to move upward. At this time, the filling piece 12 will push the plastic products in the lower mold groove 9 together. At the same time, the motor 1002 is started through the external controller, and the motor 1002 will drive the second shaft 1003 to reverse, and then drive the filling piece 12 and the plastic product to rotate. During this process, the guide wheel 603 contacts the moving plate 703 and drives the rotating shaft 1 602 to rotate. At this time, the moving plate 703 drives the rotating rod 702, the clamping plate 704 and the buffer plate 705 to rotate. At the same time, the buffer plate 705 will gradually move closer to the plastic product, so as to clamp the plastic product. At this time, the motor 1002 still drives the rotating shaft 1003 and the filling piece 12 to rotate and move upward, so that the filling piece 12 can be separated from the plastic product to achieve demoulding.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
