Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to a mold with an overload protection block. Background Technology

[0002] Molds are extremely important process equipment in industrial production, playing a significant role. They act as a "forming cradle" for products, precisely shaping and enlarging the product's shape and size according to the design. During the manufacturing process, materials are placed into the mold, and through the application of pressure or injection molding, the materials are formed in the mold cavity, ensuring the consistency and precision of the product. Whether it is plastic products, metal products, or products made of other materials, molds can efficiently assist in improving production efficiency and product quality.

[0003] However, traditional molds can be damaged if the plates are not placed neatly during operation, which can easily cause personal injury to nearby operators and result in irreparable economic losses. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a mold with an overload protection block, which can conveniently adjust the overload protection force and better adapt to different mold sizes to adjust the overload stroke.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mold with an overload protection block, comprising a base and a mounting frame. An eccentric wheel is rotatably mounted on the inner side of the top of the mounting frame, and a transmission wheel is rotatably engaged on the outer side of the eccentric wheel. A first connecting block is fixed to one side of the front end of the transmission wheel, and a second connecting block is fixed to one side of the rear end of the transmission wheel. A transmission block is mounted on the outer side of the second connecting block, and an overload block is mounted on the outer side of the transmission block. Both the transmission block and the overload block are rotatably engaged with the second connecting block via a second rotating shaft. A threaded rod is fixed to the front end of the overload block, and a limit ring is fixed to the outer side of the threaded rod. A push block is slidably mounted on the middle of the threaded rod and abuts against the limit ring. A fastening adjusting bolt is threadedly connected to the front end of the threaded rod, and a spring is sleeved on the outer side of the threaded rod and abuts against the fastening adjusting bolt and the push block respectively.

[0006] By adopting the above technical solution, when the eccentric wheel rotates, it can move the transmission wheel up and down. The transmission wheel can drive the first connecting block and the second connecting block to move synchronously. The second connecting block can drive the transmission block and the overload block to move synchronously through the second rotating shaft. The threaded rod, through the outer limiting ring, allows the push block to slide on the outside of the threaded rod while the limiting ring limits the push block. The fastening adjusting bolt adjusts the tightness of the spring through the rotational connection with the threaded rod.

[0007] Furthermore, mounting brackets are fixed on both sides of the top of the base, and a lower mold is fixed on the top of the base and inside the mounting brackets. A limit groove is fixed in the middle of the inner side of the mounting brackets.

[0008] By adopting the above technical solution, this utility model fixes mounting brackets on both sides of the top of the base and fixes the lower mold on the top of the base and inside the mounting bracket, making the mold structure more stable. A limiting slide groove is fixed in the middle of the inner side of the mounting bracket, which can limit and guide the movement of the lower pressure rod.

[0009] Furthermore, a drive motor is provided on one side of the mounting bracket and is electrically connected to an external power source through a control center. The output end of the drive motor is fixedly connected to one end of the eccentric wheel.

[0010] By adopting the above technical solution, this utility model sets a drive motor on one side of the mounting frame and electrically connects it to an external power source through a control center. This design makes the power drive of the mold more convenient and efficient. The output end of the drive motor is fixedly connected to one end of the eccentric wheel. This direct power transmission method ensures effective power transmission and stable operation.

[0011] Furthermore, a first transmission rod is provided on both sides of the first connecting block, and they are engaged by rotating through a first rotating shaft.

[0012] By adopting the above technical solution, first transmission rods are set on both sides of the first connecting block and are engaged by rotation through the first rotating shaft. This design makes the power transmission more flexible and stable.

[0013] Furthermore, a third rotating shaft is rotatably provided at the front end of the transmission block, and two sets of second transmission rods are rotatably engaged at both ends of the third rotating shaft.

[0014] By adopting the above technical solution, this utility model rotatably sets a third rotating shaft at the front end of the transmission block, and engages two sets of second transmission rods by rotating the two ends of the third rotating shaft. This design realizes further transmission and distribution of power.

[0015] Furthermore, both sets of the second and first transmission rods are rotatably engaged with the push block.

[0016] By adopting the above technical solution, this utility model connects the two sets of second transmission rods and the first transmission rod to the push block for rotational engagement. This design enables multiple transmission components to work together to form an organic whole.

[0017] Furthermore, a fourth rotating shaft is rotatably provided in the middle of the transmission block, and a lower pressing rod is rotatably engaged on the outer side of the fourth rotating shaft and engages with and slides with the limiting slide groove. An upper mold is fixed at the bottom of the lower pressing rod.

[0018] By adopting the above technical solution, a fourth rotating shaft is rotatably set in the middle of the transmission block, and the lower pressure rod is engaged by rotating the outer side of the fourth rotating shaft. This design allows the lower pressure rod to move flexibly with the movement of the transmission block, while maintaining a stable connection with the transmission block. The bottom of the lower pressure rod is fixed with an upper mold. This design directly converts the movement of the transmission block into the up and down movement of the upper mold, realizing the mold closing and opening actions.

[0019] In summary, the present invention has the following main advantages:

[0020] 1. This utility model, by setting up a transmission wheel, a first connecting block, and a second connecting block, allows the transmission wheel to move up and down when the eccentric wheel rotates eccentrically. The transmission wheel can then drive the first transmission rod, the transmission block, the overload block, and the second transmission rod to move synchronously through the first and second connecting blocks. Furthermore, the first connecting block is rotatably connected to two sets of first transmission rods through a first rotating shaft, and the second connecting block is rotatably connected to the transmission block and the overload block through a second rotating shaft. One end of the transmission block is rotatably equipped with two sets of second transmission rods through a third rotating shaft, and one end of the overload block is fixed with a threaded rod, on which a push block is slidably mounted. The push block is rotatably connected to the two sets of first and second transmission rods respectively. Thus, when the transmission block is subjected to the feedback force of the pressing rod connected through the fourth rotating shaft, it will drive the first and second transmission rods to push and unload the fastening adjusting bolt.

[0021] 2. This utility model uses a limiting ring, a push block, a fastening adjusting bolt, and a spring. By rotating the fastening adjusting bolt, the bolt is threaded onto the outside of the threaded rod, thereby adjusting the distance of the fastening adjusting bolt. A push block is slidably mounted on the outside of the threaded rod and abuts against the limiting ring fixed on the outside of the threaded rod. A spring is sleeved on the outside of the threaded rod and is located between the fastening adjusting bolt and the push block, abutting against both. By adjusting the position of the fastening adjusting bolt, the elastic thrust of the spring on the push block is increased, thereby improving the overload strength of the push block.

Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0028] In this embodiment:

[0029] A mold with an overload protection block, such as Figures 1-4 As shown, the device includes a base 1 and a mounting bracket 2. An eccentric wheel 6 is rotatably mounted on the inner side of the top of the mounting bracket 2, and a transmission wheel 7 is rotatably engaged on the outer side of the eccentric wheel 6. A first connecting block 8 is fixed to one side of the front end of the transmission wheel 7, and a second connecting block 9 is fixed to one side of the rear end of the transmission wheel 7. A transmission block 13 is mounted on the outer side of the second connecting block 9, and an overload block 14 is mounted on the outer side of the transmission block 13. Both the transmission block 13 and the overload block 14 are rotatably engaged with the second connecting block 9 through a second rotating shaft 12. A threaded rod 15 is fixed to the front end of the overload block 14, and a limit ring 16 is fixed to the outer side of the threaded rod 15. A push block 17 is slidably mounted on the middle of the threaded rod 15 and abuts against the limit ring 16. A fastening adjusting bolt 18 is threadedly connected to the front end of the threaded rod 15, and a spring 19 is sleeved on the outer side of the threaded rod 15 and abuts against the fastening adjusting bolt 18 and the push block 17 respectively.

[0030] By setting up components such as transmission wheel 7, first connecting block 8, second connecting block 9, transmission block 13, and overload block 14, and allowing them to engage through the rotation of the shaft, effective power transmission and flexible linkage between components are achieved. When the eccentric wheel 6 rotates, it can drive the transmission wheel 7 and subsequent components to move synchronously, ensuring the smoothness and accuracy of the mold operation process and effectively avoiding jamming or damage problems that may be caused by rigid connections between components. When an overload occurs during the mold operation, the push block 17 will be subjected to pressure and compress the spring 19. By adjusting the position of the fastening adjusting bolt 18 on the threaded rod 15, the preload of the spring 19 can be changed, thereby adjusting the sensitivity of the overload protection.

[0031] See Figure 1 and Figure 2Mounting brackets 2 are fixed on both sides of the top of the base 1, and a lower mold 3 is fixed on the top of the base 1 and inside the mounting bracket 2. A limit groove 4 is fixed in the middle of the inner side of the mounting bracket 2.

[0032] The base 1 provides stable support for the lower mold 3, ensuring that the lower mold 3 will not shift or shake during operation, thereby ensuring the accuracy and stability of the mold operation. When the pressure rod 23 slides, the limiting groove 4 ensures that these components move along the predetermined trajectory, preventing them from shifting or misaligning, and further improving the accuracy and reliability of the mold operation.

[0033] See Figure 1 , Figure 2 and Figure 3 A drive motor 5 is provided on one side of the mounting bracket 2 and is electrically connected to an external power source through the control center. The output end of the drive motor 5 is fixedly connected to one end of the eccentric wheel 6.

[0034] The control center can precisely control the start, stop, and speed of the drive motor 5, thereby achieving precise control of the mold operation process, meeting different operational needs, improving production efficiency and product quality. When the drive motor 5 is running, it can drive the eccentric wheel 6 to rotate stably.

[0035] See Figure 1 , Figure 2 , Figure 3 and Figure 4 The first connecting block 8 is provided with a first transmission rod 11 on both sides, and is engaged by the first rotating shaft 10.

[0036] When the first connecting block 8 is driven by the transmission wheel 7 to move, it can smoothly transmit power to the first transmission rods 11 on both sides through the first rotating shaft 10, ensuring that the first transmission rods 11 on both sides can work synchronously and stably, avoiding mold action errors or damage caused by uneven force on one side or poor transmission.

[0037] See Figure 1 , Figure 2 , Figure 3 and Figure 4 The front end of the transmission block 13 is rotatably provided with a third rotating shaft 20, and the two ends of the third rotating shaft 20 are rotatably engaged with two sets of second transmission rods 21.

[0038] When the transmission block 13 is driven by the overload block 14 or other components to move, it can transmit power to the two sets of second transmission rods 21 through the third rotating shaft 20, so that they can work synchronously and in coordination, thereby ensuring the smoothness and accuracy of the mold movement.

[0039] See Figure 1 , Figure 2 , Figure 3 and Figure 4 Both sets of second transmission rods 21 and first transmission rods 11 are rotatably engaged with push block 17;

[0040] When the transmission block 13 or the first connecting block 8 is subjected to external force, they can transmit power to the push block 17 through the second transmission rod 21 and the first transmission rod 11, so that the push block 17 can move or move accordingly, thereby realizing the overload protection of the mold or other specific functions.

[0041] See Figure 1 , Figure 2 , Figure 3 and Figure 4 The transmission block 13 has a fourth rotating shaft 22 rotatably mounted in the middle, and the outer side of the fourth rotating shaft 22 is rotatably engaged with a lower pressing rod 23, which is engaged with and slides in the limiting slide groove 4. The bottom of the lower pressing rod 23 is fixed with an upper mold 24.

[0042] In particular, since the lower pressure rod 23 engages and slides with the limiting slide groove 4, the movement trajectory of the lower pressure rod 23 is further restricted, ensuring that it moves along the predetermined path, which improves the accuracy and stability of the mold operation. The upper mold 24 can accurately and quickly cooperate with the lower mold 3, improving the mold operation efficiency and product quality.

[0043] The implementation principle of this embodiment is as follows: First, the base 1 is stably placed in the designated position. Then, the plate to be processed is placed on the top of the lower mold 3. Next, the drive motor 5 is turned on through the control center, causing the drive motor 5 to drive the eccentric wheel 6 to rotate. When the eccentric wheel 6 rotates eccentrically, it will drive the transmission wheel 7 to move up and down. The transmission wheel 7 can then drive the first transmission rod 11, the transmission block 13, the overload block 14, and the second transmission rod 21 to move synchronously through the first connecting block 8 and the second connecting block 9, respectively. Furthermore, the first connecting block 8 is rotatably connected to the two sets of first transmission rods 11 through the first rotating shaft 10, and the second connecting block 10 is rotatably connected to the two sets of first transmission rods 11 through the first rotating shaft 10. 9 is rotatably connected to the transmission block 13 and the overload block 14 via the second rotating shaft 12. One end of the transmission block 13 is rotatably provided with two sets of second transmission rods 21 via the third rotating shaft 20. One end of the overload block 14 is fixed with a threaded rod 15, and a push block 17 is slidably provided on the threaded rod 15. The push block 17 is rotatably connected to the two sets of first transmission rods 11 and second transmission rods 21 respectively. When there are foreign objects between the lower mold 3 and the upper mold 24, the transmission block 13 will be driven by the feedback force of the lower pressure rod 23 connected via the fourth rotating shaft 22, which will drive the first transmission rod 11 and the second transmission rod 21 to push and unload the fastening adjustment bolt 18.

[0044] Then, by rotating the fastening adjusting bolt 18, the fastening adjusting bolt 18 is threaded to the outside of the threaded rod 15, thereby adjusting the distance of the fastening adjusting bolt 18. A push block 17 is slidably arranged on the outside of the threaded rod 15 and abuts against the limiting ring 16 fixed on the outside of the threaded rod 15. A spring 19 is sleeved on the outside of the threaded rod 15 and is located between the fastening adjusting bolt 18 and the push block 17 and abuts against the fastening adjusting bolt 18 and the push block 17. By adjusting the position of the fastening adjusting bolt 18, the elastic thrust of the spring 19 on the push block 17 is increased, thereby improving the overload strength of the push block 17.
