[0020] 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.

[0021] Refer to Figures 1-3 , an automatic blanking device for PEEK rod-shaped injection molded parts, including a static mold 1, a moving mold 2 and an injection pipe 8. The injection pipe 8 is inserted on the side of the static mold 1 away from the moving mold 2. An opening is provided in the support plate 12. One end of the injection pipe 8 penetrates through the static mold 1 and the opening and extends into the mold cavity. Mold cavities are provided on the opposite sides of the static mold 1 and the moving mold 2;

[0022] In this embodiment, chutes are provided in both the static mold 1 and the moving mold 2. Vertically arranged support plates 12 are slidably connected to the inner side walls of the chutes for driving the ejector pins 9 to move. Arc-shaped grooves are provided at both the upper and lower ends of the support plates 12. Ball bearings 10 are rotatably connected to the inner side walls of the arc-shaped grooves for reducing the resistance when the support plates 12 move. Part of the ball bearings 10 penetrates through the arc-shaped grooves. A rubber pad 6 is fixedly connected to the side of the support plate 12 away from the spring 3 for preventing wear between the support plate 12 and the chute. Four connecting rods 4 distributed in a rectangular shape are provided between the static mold 1 and the moving mold 2 for supporting the support plate 12. The connecting rods 4 are horizontally arranged. Both ends of the connecting rods 4 slidably penetrate through the static mold 1 and the moving mold 2 respectively and are fixedly connected to the support plate 12. Second fixing rings 11 are fixedly sleeved on both ends of the connecting rods 4 for improving the firmness between the connecting rods 4 and the support plate 12. One side of the second fixing ring 11 is fixedly connected to the outer side wall of the support plate 12;

[0023] In this embodiment, springs 3 are fixedly connected to the opposite sides of the two support plates 12 for elastically supporting the support plates 12. The ends of the springs 3 away from the support plates 12 are fixedly connected to the inner side walls of the chutes. Support rods 5 are slidably inserted into the springs 3 for supporting the springs 3 and preventing them from skewing. One end of the support rod 5 is fixedly connected to the inner side wall of the chute. The other end of the support rod 5 sequentially slides through the spring 3 and the support plate 12 and is fixedly connected to the inner side wall of the chute. A horizontally arranged ejector pin 9 is fixedly connected to the side of the support plate 12 close to the spring 3 for ejecting the formed workpiece. A through hole communicating with the chute is provided on the inner side wall of the mold cavity. One end of the ejector pin 9 slides through the through hole. A first fixing ring 7 is fixedly sleeved on the ejector pin 9 for improving the firmness between the ejector pin 9 and the support plate 12. One side of the first fixing ring 7 is fixedly connected to the outer side wall of the support plate 12.

[0024] In this embodiment, when the mold is opened, the moving mold 2 moves away from the stationary mold 1. At this time, the moving mold 2 moves horizontally along with the connecting rod 4. As it moves, the ejector pin 9 moves into the mold cavity, and the workpiece in the mold cavity is ejected by the ejector pin 9, realizing automatic blanking operation, and the ejection operation can be carried out on the interiors of two mold cavities simultaneously. Whether the workpiece is in the stationary mold 1 or the moving mold 2, it can be ejected. After the mold is closed, the support plate 12 is pushed to move back to its original position by the elasticity of the spring 3, and the ejector pin 9 is driven by the support plate 12 to move back to its original position, avoiding affecting the forming of the workpiece in the mold cavity.

[0025] As described above, the stationary mold, the moving mold, and the injection pipe have been disclosed in the comparative document or are existing mature technologies. Their working principles and internal structures are known to those skilled in the art. This application only utilizes their functions and does not improve their internal structures. Therefore, no detailed description will be given.

[0026] As described above, the above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent replacements or changes, and should be covered within the protection scope of the present utility model.
