[0017] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of an injection molding mold for PEEK blades of an automotive brake vacuum pump, comprising a mold 1 and a mold 2. A locking frame 3 is fixedly connected to the outer wall of the mold 2. A positioning post 4 is provided inside the mold 1. The outer wall of the mold 1 fits against the outer wall of the mold 2. The outer wall of the positioning post 4 is slidably connected to the inside of the mold 2. An electric push rod 5 is fixedly connected inside the mold 1. The output end of the electric push rod 5 passes through the inside of the mold 1 and is fixedly connected to a clamping frame 6. A sliding rod 7 is slidably connected inside the clamping frame 6. A toothed plate 8 is fixedly connected to the outer wall of the clamping frame 6. A gear 9 is meshed with the toothed end of the toothed plate 8. A support rod 10 is fixedly connected inside the gear 9. The outer wall of the clamping frame 6 is set on the outer wall of the locking frame 3. A limit component is provided inside the mold 1. Specifically, mold 1 and mold 2 are connected to the injection molding machine. The injection molding machine is a well-known technology and will not be described in detail here. Mold 1 has a groove inside, which connects to the demolding mechanism of the injection molding machine for demolding the blades. Mold 2 has a groove inside, which connects to the injection molding mechanism of the injection molding machine for injection molding of the cavity formed after mold 1 and mold 2 are fitted together. Positioning pins 4 are set around mold 1 for positioning mold 2 when it is fitted together with mold 1. Mold 1 has a groove inside for fixing the electric push rod 5 and also leaves some space. The sliding rod 7 supports and restricts the movement of the clamping frame 6. The toothed plate 8 meshes with the gear 9 and is fixed to the clamping frame 6. As the gear 9 and the support rod 10 rotate, the upper and lower clamping frames 6 can move in opposite directions. The outer wall of the clamping frame 6 matches the outer wall of the locking frame 3, which facilitates the clamping frames 6 on both sides to clamp or release the locking frame 3.

[0019] Reference Figure 3 The limiting component includes a slide rail 11, the outer wall of which is fixedly connected to the inside of the mold 1, and the outer wall of which is slidably connected to the inside of the toothed plate 8. Specifically, the mold 1 fixes the slide rail 11 inside, and the toothed plate 8 slides on the outer wall of the slide rail 11 inside, thereby supporting and restricting the movement of the toothed plate 8.

[0020] Reference Figure 3 The outer wall of the clamping frame 6 is slidably connected to the inside of the mold 1, both ends of the slide rod 7 are fixedly connected to the inside of the mold 1, and both ends of the support rod 10 are rotatably connected to the inside of the mold 1. Specifically, the groove inside the mold 1 restricts the movement range of the clamping frame 6, fixes the slide rod 7, and supports and limits the rotation of the support rod 10.

[0021] Reference Figure 1 , Figure 4 and Figure 5A transmission rod 12 is slidably connected inside mold 1, and a limit rod 13 is fixedly connected to the outer wall of the transmission rod 12; the outer wall of the limit rod 13 is slidably connected inside mold 1, and a disc 14 is slidably connected to the outer wall of the limit rod 13; the outer wall of the disc 14 is fixedly connected to the inside of mold 1, and a spring 15 is fixedly connected to the outer wall of the disc 14; a fixing rod 16 is fixedly connected to the outer wall of the spring 15; the outer wall of the fixing rod 16 is located inside mold 1, and the outer wall of the fixing rod 16 is fixedly connected to the outer wall of the limit rod 13; the outer wall of the limit rod 13 is located inside the positioning post 4, and a fixing block 17 is slidably connected inside the positioning post 4, and the outer wall of the fixing block 17 is fixedly connected to the inside of mold 1. Specifically, the mold 1 has a groove inside for the movement of the transmission rod 12. The transmission rod 12 is located inside the mold 1 to avoid affecting its use. The movement of the limiting rod 13 is restricted by the mold 1 and the disc 14. The movement of the fixing rod 16 is limited by the groove inside the mold 1. The spring 15 is used to hold the fixing rod 16 in place, providing support for the limiting rod 13 inside the positioning post 4. The positioning post 4 has a groove inside, so that the opening of the groove is located at the fixing block 17, allowing the positioning post 4 to slide completely into the mold 1. Then, the positioning post 4 is rotated backward, causing the fixing block 17 to slide within the groove of the positioning post 4. When the positioning post 4 is rotated to the bottom, the limiting rod 13 can slide into the positioning post 4 for limiting, thus improving the stability of the positioning post 4 installation.

[0022] Working principle: When using this mold, connect mold 1 and mold 2 to the injection molding machine, fix mold 1, and push mold 2 to move towards mold 1. The movement of mold 2 is positioned by the positioning pin 4. At the same time, when mold 1 and mold 2 are in contact, the locking frame 3 slides into the interior of mold 1, located within the range of the clamping frames 6 on both sides. The electric push rod 5 pushes the clamping frame 6, causing the clamping frame 6 and the toothed plate 8 to move upward under the limit of the sliding rod 7, thereby driving the gear 9 and the support rod 10 to rotate. This causes the clamping frames 6 on both sides to move toward the support rod 10, clamping and fixing the locking frame 3, thus locking the movement of mold 1 to mold 2, preventing accidental demolding during injection molding. The groove inside mold 2 facilitates injection molding by the injection molding machine. The locking of mold 1 and mold 2 facilitates injection molding. During demolding, the electric push rod 5 pulls the clamping frame 6 to release the locking frame 3, facilitating the departure of mold 2. The demolding mechanism demolds the molded blade through the groove inside mold 1. When maintenance is required on the positioning post 4, the transmission rod 12 is pulled, causing the limiting rod 13 to slide inside the mold 1 and the disc 14. This causes the fixing rod 16 to move forward, compressing the spring 15. The positioning post 4 then slides out of the mold 1 through the limiting rod 13, no longer limiting its position. The positioning post 4 is then rotated forward inside the mold 1, so that the fixing block 17 is located inside the opening of the positioning post 4. This allows the positioning post 4 to slide out of the mold 1 for maintenance. During use, this mold not only locks the mold 1 and mold 2 during injection molding but also allows for the installation and removal of the positioning post 4, facilitating maintenance and replacement.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
