DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0028] Please refer to Figure 1 and Figure 3 - Figure 5 In the embodiment, a centrifugal casting floating oil seal ring composite mold comprises a mounting frame 1, the top of the mounting frame 1 is fixedly connected with a cooling ring 2, the inside of the cooling ring 2 is rotatably connected with a mold body 3, and the top of the mold body 3 is provided with a top cover 25.

[0029] Specifically, the mounting frame 1 serves as the support structure of the whole mold, the cooling ring 2 is used for cooling the mold body 3 during casting, ensuring that the liquid alloy can be quickly solidified and formed in the mold, which is the prior art, and the top cover 25 covers the top of the mold body 3 to prevent the liquid metal from spattering out during casting.

[0030] The inside of the mold body 3 is provided with an ejection assembly, the ejection assembly comprises an ejection frame 4, the ejection frame 4 is slidably connected to the inside bottom of the mold body 3, the bottom of the ejection frame 4 is fixedly connected with two fixed frames 5, the bottom of each of the two fixed frames 5 is rotatably connected with a connecting rod 6, the bottom of each of the two connecting rods 6 is rotatably connected with a moving frame 7, the bottom of each of the two moving frames 7 is fixedly connected with a sliding block 8, the inside of the mold body 3 is rotatably connected with a two-way threaded rod 9, each of the two sliding blocks 8 is threadedly connected to the outer periphery of the two-way threaded rod 9, the inside of the mold body 3 is provided with a driving assembly, the driving assembly comprises a motor 10, the motor 10 is fixedly connected to the inside of the mold body 3, the output end of the motor 10 is fixedly connected to the left side of the two-way threaded rod 9, the inside of the mold body 3 is fixedly connected with two limit rods 11, each of the two sliding blocks 8 is slidably connected to the outer periphery of the two limit rods 11, the inside of the mold body 3 is fixedly connected with an anti-collision rod 12, and the middle of the two-way threaded rod 9 is rotatably connected to the inside of the anti-collision rod 12.

[0031] Specifically, the ejector 4 is located at the bottom inside the mold body 3. Its main function is to directly contact and eject the cast oil seal ring during demolding. The fixed frame 5 connects the ejector 4 to the connecting rod 6. The connecting rod 6 plays a power transmission role between the fixed frame 5 and the moving frame 7, so that the rotational motion of the bidirectional threaded rod 9 can be converted into the linear lifting motion of the ejector 4. The sliding block 8 is threadedly connected to the bidirectional threaded rod 9. When the bidirectional threaded rod 9 rotates, it can only slide linearly along the limit rod 11 due to the restriction of the limit rod 11, thereby driving the connecting rod 6 to move. The motor 10 is set inside the mold body 3 to provide power for the rotation of the bidirectional threaded rod 9. The limit rod 11 plays a precise guiding and limiting role for the movement of the sliding block 8, ensuring that the movement of the sliding block 8 is smooth. The anti-collision rod 12 is used to prevent the two sliding blocks 8 from colliding.

[0032] Please see Figure 2 , Figure 6 and Figure 7 In this embodiment, a support shaft 13 is rotatably connected to the bottom of the mounting bracket 1, and a coupling 14 is fixedly connected to the bottom of the support shaft 13. A quick-release assembly is provided inside the support shaft 13, which includes two push rods 17. Both push rods 17 are slidably connected inside the support shaft 13. Two support frames 18 are fixedly connected to the outer periphery of each of the two push rods 17. A connecting rod 19 is fixedly connected to one side of each of the two support frames 18. A sliding frame 20 is rotatably connected to the other end of each of the two connecting rods 19, and a sliding rod 2 is fixedly connected to the other end of each of the two sliding frames 20. 1. Two fixed rods 23 are fixedly connected inside the support shaft 13. Two push rods 17 are slidably connected to the outer periphery of the two fixed rods 23. Springs 24 are sleeved on the outer periphery of the two fixed rods 23. Two pins 15 are fixedly connected to the bottom of the mold body 3. Two slots 16 are opened at the top of the support shaft 13. The two pins 15 are slidably connected to the two slots 16. Two sliding rods 21 are engaged inside the pins 15. Multiple sliding rods 22 are fixedly connected inside the support shaft 13. Multiple sliding rods 21 are slidably connected to the outer periphery of multiple sliding rods 22.

[0033] Specifically, the support shaft 13 drives the mold body 3 to rotate, and the coupling 14 at its bottom can be used to connect external power equipment to realize the rotation drive of the mold body 3. The push rod 17 slides inside the support shaft 13. Pressing the push rod 17 can drive the support frame 18 to move. The support frame 18 is fixed on the outer periphery of the push rod 17 and serves to connect the push rod 17 and the connecting rod 19. The connecting rod 19 connects the support frame 18 and the sliding frame 20, so that the linear motion of the push rod 17 can be converted into the swing motion of the sliding frame 20. The sliding frame 20 drives the sliding rod 21 to slide on the sliding rod 22, realizing the engagement or disengagement with the pin 15, thus completing the rotation. The quick connection or separation operation between the mold body 3 and the support shaft 13 is achieved through the fixing rod 23 guiding and restricting the sliding of the push rod 17, ensuring smooth movement of the push rod 17. The spring 24 is sleeved on the outer circumference of the fixing rod 23. When the push rod 17 is pressed, it is compressed, and when released, the spring force allows the push rod 17 to return to its original position, facilitating repeated operation. The cooperation between the pin 15 and the slot 16 achieves the initial positioning of the mold body 3 and the support shaft 13, ensuring the accuracy of installation. The engagement between the sliding rod 21 and the pin 15 further enhances the stability of the connection. The sliding rod 22 provides guidance for the sliding of the sliding rod 21, ensuring smooth sliding and reliable quick-installation operation.

[0034] The working principle and usage process of this utility model are as follows: When the oil seal ring is cast and needs to be demolded, the operator starts the motor 10. The motor 10 drives the bidirectional threaded rod 9 to rotate. Since the bidirectional threaded rod 9 is threadedly connected to two sliding blocks 8, and the sliding blocks 8 are restricted by the limit rod 11 to only make linear movements, the rotation of the bidirectional threaded rod 9 will cause the two sliding blocks 8 to move towards or away from each other. The movement of the sliding blocks 8 drives the fixed frame 5 to move through the connecting rod 6, thereby causing the ejector frame 4 to rise or fall. When the ejector frame 4 rises, the cast oil seal ring can be ejected from the mold body 3, realizing efficient demolding operation, greatly saving the time and effort required for manual demolding, and effectively improving the product yield.

[0035] When it is necessary to install or disassemble the mold body 3, the operator presses the two push rods 17. The push rods 17 slide on the fixed rod 23 inside the support shaft 13 and compress the spring 24. The movement of the push rods 17 drives the support frame 18 to move. The support frame 18 causes the sliding frame 20 to swing through the connecting rod 19, thereby causing the sliding rod 21 to slide on the sliding rod 22, so that the sliding rod 21 is disengaged from the bottom pin 15 of the mold body 3. At this time, the connection between the mold body 3 and the support shaft 13 is released, and the separation operation can be performed. When installing the mold body 3, first press the push rod 17, align the pin 15 at the bottom of the mold body 3 with the slot 16 for installation. After installation in the original position, release the push rod 17. The spring force of the spring 24 causes the push rod 17 to return to its original position, pushing the sliding rod 21 to re-engage with the pin 15, completing the installation. The operation is simple and quick, improving the installation and maintenance efficiency of the mold, reducing equipment downtime, and helping to improve production efficiency.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
