Description
Technical Field
[0001] This utility model relates to the field of mold technology, and in particular to a mold frame with an adjustable function. Background Technology
[0002] The mold base is the supporting structure of a mold, providing a mounting foundation and guiding function for the working parts of the mold (such as cavities and cores). Think of the mold base as the "skeleton" of the mold; other components of the mold depend on the mold base for their functions. For example, in an injection mold, the mold base supports the injection cavity and core, ensuring their accurate relative positions during injection, allowing the plastic to smoothly fill the cavity.
[0003] A stamping die set consists of an upper die base and a lower die base. The upper die (including components such as the punch) is mounted on the upper die base, and the lower die (including components such as the die cavity) is mounted on the lower die base. The guiding devices of the die set (such as guide pillars and guide sleeves) ensure that the upper and lower dies can be precisely aligned during the stamping process. After the die is installed, the guide pillars are inserted into the guide sleeves, restricting the movement direction of the upper die relative to the lower die, so that the punch can be accurately aligned with the die cavity, ensuring the accuracy of the stamping.
[0004] In the prior art, due to design differences, manufacturing errors, or matching issues with molding equipment, some molds in a mold set may experience wear or slight deformation as the mold is used more times, resulting in product deviations during processing. Therefore, a mold set with adjustment function is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above deficiencies, this utility model provides a mold frame with an adjustable function, which aims to improve the problem in the prior art where, due to design differences, manufacturing errors, or matching problems with molding equipment, some parts of the mold may wear or slightly deform as the number of times the mold is used increases, resulting in product deviations during processing.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:

An adjusting ring is slidably connected to the outside of the mounting column. The inside of the die has multiple cavities. A second spring is fixedly connected to the inner wall of each cavity. A locking block is fixedly connected to the other end of the second spring.
[0010] As a further description of the above technical solution:
[0011] The outer side of the adjusting ring contacts the outer side of the locking block, the top of the locking block contacts the outer side of the mounting post, and the outer side of the locking block is slidably connected to the inner wall of the cavity;
[0012] As a further description of the above technical solution:
[0013] One end of the spring away from the mounting post is fixedly connected to the inner wall of the bottom end of the sliding groove, and the outer side of the top post is in contact with the inner wall of the slot.
[0014] As a further description of the above technical solution:
[0015] The mounting post is externally slidably connected to the inside of the mounting groove, and the mounting post is externally slidably connected to the inside of the connecting plate;
[0016] As a further description of the above technical solution:
[0017] The protective assembly includes a fixed post, the bottom of which is fixedly connected to the bottom of the base.

[0023] 1. In this utility model, by rotating the adjusting column, the top column can be pushed to contact the slot outside the mounting column, and the position of the die on the top of the mounting column can be adjusted. During the adjustment process, the spring is compressed by force, and then the adjusting column is rotated to make the top column abut against the slot, which can fix the mounting column and keep the die stable.

Detailed Implementation
[0031] 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.
[0032] Reference Figures 1 to 3This utility model provides an embodiment of a mold frame with an adjustable function, including a base 1. The base 1 serves as the basic support component of the entire mold frame, bearing the heavy responsibility of stabilizing the entire device. A lower mold base 2 is fixedly connected to the top of the base 1, which is a key platform for supporting the core components of the mold. The lower mold base 2 has multiple sliding grooves 3 inside, and a connecting seat 4 is fixedly connected to the inner wall of the sliding groove 3. The sliding groove 3 is an important internal structure of the lower mold base 2, and is in the shape of a regular groove. The inner wall is finely polished and chrome-plated, resulting in extremely low friction, which facilitates the rapid and smooth sliding of the connecting seat 4.
[0033] The connecting seat 4 plays a crucial connecting role. An internal sliding connection of mounting posts 5 is provided within the connecting seat 4. The tops of multiple mounting posts 5 are detachably connected to the die cavity 11. The mounting posts 5 serve as the connecting hub between the die cavity 11 and the lower die base 2. A spring 6 is fixedly connected to the bottom of the mounting posts 5. The end of the spring 6 furthest from the mounting posts 5 is fixedly connected to the bottom inner wall of the sliding groove 3. When the die cavity 11 is pressed down to adjust its height, the spring 6 is compressed and stores elastic potential energy. Once the external force is removed, the spring 6, with its strong rebound tension, pushes the mounting posts 5 and the die cavity 11 back up, ensuring the die cavity 11 is accurately reset, maintaining the stability and consistency of the die height, and guaranteeing the accuracy of the stamping process.
[0034] The mounting post 5 has a slot 7 on its outside. The base 1 has an internal threaded connection to an adjusting post 9. The end of the adjusting post 9 near the slot 7 is fixedly connected to a top post 8. The inner wall of the slot 7 is smooth, which facilitates the smooth entry and exit of the top post 8. The outside of the top post 8 is in contact with the inner wall of the slot 7. When the adjusting post 9 is rotated, the top post 8 extends and retracts smoothly, accurately controlling the locking and unlocking state of the mounting post 5 and completing the height adjustment operation of the die 11. When the top post 8 is fully inserted into the slot 7, it can provide stable support for the mounting post 5 and resist the impact vibration.
[0035] The die 11 is firmly fixed at the required height position. The die 11 is equipped with a limiting component inside. The limiting component can limit the die 11. As a key component of mold forming, the die 11 directly contacts the stamped workpiece. The limiting component includes a connecting plate 10. The inside of the connecting plate 10 is slidably connected to the outside of the mounting post 5. The size of the hole on the plate is perfectly matched with the mounting post 5, guiding the mounting post 5 to pass smoothly and restricting the horizontal movement of the die 11. This helps the die 11 to be accurately positioned and maintains the stamping accuracy.
[0036] The bottom of the die 11 has multiple mounting slots 12. The mounting post 5 is externally slidably connected to the inside of the mounting slot 12. The mounting slot 12 is reinforced with ribs to strengthen the bottom structure of the die 11, preventing deformation under stamping pressure and ensuring a stable connection between the die 11 and the mounting post 5. The mounting post 5 is externally slidably connected to the inside of the connecting plate 10. An adjusting ring 13 is also externally slidably connected to the mounting post 5. The die 11 has multiple cavities 14, forming a regular cylindrical space. A second spring 15 is fixedly connected to the inner wall of each cavity 14. A locking block 16 is fixedly connected to the other end of the second spring 15. The second spring 15 pushes the locking block 16 out, so that its top contacts the mounting post 5, locking the die 11. When the adjusting ring 13 is pressed, the second spring 15 is compressed, the locking block 16 retracts, and the die 11 is unlocked, ensuring convenient replacement and maintenance of the die 11.
[0037] The outer side of the adjusting ring 13 contacts the outer side of the locking block 16. When the die 11 needs to be replaced or maintained, the die 11 is pressed down, and the adjusting ring 13 descends accordingly, squeezing the locking block 16 to slide into the cavity 14, unlocking the connection between the die 11 and the mounting post 5. The surface of the adjusting ring 13 is smooth, ensuring smooth contact with the locking block 16 and reliable operation. The top of the locking block 16 contacts the outer side of the mounting post 5, and the outer side of the locking block 16 is slidably connected to the inner wall of the cavity 14. When the adjusting ring 13 is activated, the locking block 16 is precisely retracted and extended with the assistance of the spring 15, realizing the locking and unlocking function of the die 11 and maintaining the stability of the mold structure.
[0038] Reference Figure 4 The base 1 is equipped with protective components at its four top corners. These protective components can protect the lower mold base 2. The protective components include a fixed column 17, the bottom of which is fixedly connected to the bottom of the base 1. A sleeve 18 is slidably connected inside the fixed column 17. The sleeve 18 has a hollow internal structure, which provides space for the sleeve 18 to slide up and down. The inner wall is honed to reduce the sliding friction of the sleeve 18 and enhance the stability and reliability of the protective components. When the sleeve 18 is subjected to force, it can slide smoothly up and down inside the fixed column 17 to absorb and buffer the stamping vibration energy and protect the mold and the base 1.
[0039] The sleeve 18 has a sliding connection to the connecting post 19 inside. The connecting post 19 is slidably connected to the top through hole of the fixed post 17 outside. The bottom of the connecting post 19 is fixedly connected to the damper 20. When subjected to impact force, the damper 20 responds quickly, absorbs energy smoothly, suppresses vibration amplitude, avoids instantaneous burst of impact force that could damage the mold and equipment, and extends service life. The top of the multiple connecting posts 19 is fixedly connected to the upper mold base 23. The force on the upper mold base 23 is evenly distributed to the connecting posts 19, and then buffered and damped by the protective components to ensure a smooth and efficient stamping process. It is a key bearing platform for the stamping process.
[0040] During the stamping process, the connecting column 19 moves down synchronously with the upper die holder 23, transmitting the impact force to the sleeve 18 and the damper 20, working together to buffer and reduce shock, maintaining the stability of the stamping. A spring 22 is fitted on the outside of the sleeve 18, and a pad 21 is fixedly connected to the inner wall of the bottom end of the fixed column 17. When the sleeve 18 slides down to the bottom, the pad 21 provides buffer contact, flexibly bearing the impact force, reducing noise, preventing the sleeve 18 from directly hitting the fixed column 17 and causing damage, and ensuring the integrity of the protective components. One end of the spring 22 is fixedly connected to the outside of the sleeve 18, and the other end of the spring 22 is fixedly connected to the outside of the pad 21. During stamping, it is further compressed to store elastic potential energy, absorbing and converting the impact force. After the stamping is completed, the sleeve 18 is pushed back to its original position due to its strong rebound characteristics, maintaining the dynamic balance of the protective components and continuously exerting the buffering and shock-absorbing effect.
[0041] Working principle: First, place the base 1 in a suitable position, then rotate the adjusting column 9. When the adjusting column 9 rotates, the top column 8 moves outward and separates from the slot 7. At this time, the height of the die 11 can be adjusted by pressing or lifting. When the die 11 is pressed, the mounting column 5 is forced downward to compress the spring 6. After adjustment, rotate the adjusting column 9 so that the top column 8 abuts against the slot 7, which can fix the mounting column 5, thereby fixing the die 11 and realizing the fine adjustment of the height of the die 11. When the die 11 needs to be replaced or maintained, press down on the four corners of the die 11 so that the mounting column 5 is forced to slide downward inside the connecting seat 4. At the same time, the adjusting ring 13 contacts the bottom of the connecting seat 4, and the locking block 16 slides into the cavity 14 under the pressure of the adjusting ring 13, so that the spring 15 is compressed. When the adjusting ring 13 and the locking block 16 are no longer in contact, they will also separate from the top of the mounting column 5. At this time, the die 11 can be removed for replacement and maintenance.
[0042] During the stamping process, the connecting column 19 slides down inside the sleeve 18 along with the upper die holder 23. The sleeve 18 is forced downward to compress the spring 3 22. When the bottom of the sleeve 18 contacts the gasket 21, the gasket 21 will buffer and protect the sleeve 18, maintaining the stability of the base 1 during the stamping process.
[0043] 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.
