[0023] 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.
[0024] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model provides a precision machining fixture for die casting mold cores, including a mounting box 1, a fixing plate 2 fixedly connected to the top of the mounting box 1, a disassembly mechanism fixedly connected to the outside of the fixing plate 2, and a limit mechanism fixedly connected to the inside of the mounting box 1.
[0025] The limiting mechanism includes two mounting bases 11, which are fixedly connected inside the mounting box 1. An electric push rod 12 is fixedly connected to the top of the mounting base 11. A fixed cover 16 is fixedly connected to the output end of the electric push rod 12. A slider 14 is fixedly connected to the bottom of the fixed cover 16. A sliding groove 15 is provided inside the mounting box 1. The slider 14 is slidably connected inside the sliding groove 15. An electric push rod 13 is provided inside the fixed cover 16. A lifting assembly is provided on the top of the fixed cover 16. The lifting assembly includes two positioning plates 17, which are fixedly connected to the top of the fixed cover 16. A lifting plate 18 is fixedly connected to the output end of the electric push rod 13. The outside of the lifting plate 18 is slidably connected to the inside of the positioning plate 17. A clamping plate 19 is fixedly connected to the outside of the lifting plate 18. A slot 21 is provided on the top of the mounting box 1. A positioning plate 17 is slidably connected inside the slot 21. A protective pad 20 is fixedly connected to the outside of the positioning plate 17.
[0026] Through the design of electric push rod 12 and fixed cover 16, combined with the lifting assembly of electric push rod 2 13, the relative position of the core can be quickly adjusted to ensure that the mold core can be quickly and accurately positioned to the precise position required for processing. The combined design of lifting plate 18 and clamping plate 19 can move up and down slowly to accurately clamp the core. Through the downward pressing action of clamping plate 19, the core is firmly fixed in the tooling to prevent it from moving due to vibration or external force during processing, thereby improving the processing accuracy and consistency of the mold. The stable structure of the protective pad 20 of positioning plate 17, pull rod 10 and limit rod 9 further enhances the stability of the tooling and reduces wear problems during long-term high-intensity use.
[0027] Reference Figure 1 , Figure 2 and Figure 3 The disassembly mechanism includes two mounting blocks 5, which are fixedly connected to the outside of the fixed plate 2. The mounting blocks 5 have mounting grooves 6 inside, and a sliding plate 7 is slidably connected inside the mounting grooves 6. A limit rod 9 is fixedly connected inside the sliding plate 7, and a spring 8 is provided outside the limit rod 9. The end of the spring 8 near the fixed plate 2 is fixedly connected to the outside of the limit rod 9, and the end of the spring 8 away from the fixed plate 2 is fixedly connected to the inside of the mounting groove 6. A placement plate 3 is provided inside the fixed plate 2, and each placement plate 3 has a limit hole 4 inside. Each limit hole 4 has a limit rod 9 inside, and a pull rod 10 is fixedly connected to the end of the limit rod 9 away from the fixed plate 2. The outside of the limit rod 9 is slidably connected to the inside of the fixed plate 2, and the outside of the limit rod 9 is slidably connected to the inside of the mounting blocks 5.
[0028] The design of the pull rod 10 and the limit rod 9 allows the placement plate 3 to be easily disassembled or replaced. This structural design facilitates switching between mold cores of different sizes and shapes, making it particularly suitable for production environments that require frequent core changes. Because disassembly and replacement are simple and quick, downtime is greatly reduced. The replaceable placement plate 3 can accommodate mold cores of different shapes and sizes, thereby improving the adaptability and flexibility of the tooling, adapting to various production needs, increasing the overall automation and mechanization of the structure, reducing the workload of operators, and improving production efficiency.
[0029] Working principle: In use, the placement plate 3 containing the mold core is installed inside the fixed plate 2. At this time, the two sets of electric push rods 12 are driven to move. The electric push rods 12 drive the fixed cover 16 to move. The fixed cover 16 moves simultaneously, driving the positioning plate 17 and the lifting plate 18 to move. The push rod positioning plate 17 limits the two sides of the mold core. At the same time, the electric push rod 13 drives the lifting plate 18 and the clamping plate 19 to limit and fix the top of the mold core. This ensures that the die-casting mold core can maintain a stable position during processing, which helps to improve the processing accuracy of the mold. When it is necessary to replace the mold core placement plate 3, the pull rod 10 and the limit rod 19 are pulled to fix the mold core. The positioning rod 9 is pulled to disengage the limiting rod 9 from the inside of the limiting hole 4. At this time, the placement plate 3 is removed from the inside of the fixing plate 2. This facilitates the fixing and replacement of the placement plate 3. During the clamping process, mold cores of different shapes and sizes may need to be clamped. At this time, the core placement plate 3 can be replaced and adjusted to facilitate better clamping effect and improve the practicality and stability of the device. When installing, pull the lever 10 again to disengage the limiting rod 9 from the inside of the fixing plate 2. To insert the new placement plate 3, release the lever 10. Then, the spring force of the spring 8 drives the sliding plate 7 and the limiting rod 9 to reset and clamp, thereby completing the replacement.
[0030] 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.
