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.

[0022] Please see Figures 1-6This utility model provides a technical solution: a mold for ejecting and preventing deformation of a sealing ring, comprising a base 1, a mold plate 2, and an upper mold 3. The top of the base 1 is connected to the mold plate 2 via a column, and the bottom center of the mold plate 2 is connected to the upper mold 3. A left mold 4 is provided on one side of the top of the base 1, and a right mold 5 is provided on the other side of the top of the base 1. A part-removing mechanism 6 is provided below the upper mold 3, and the part-removing mechanism 6 includes a drive motor 601, a first bevel gear 602, a second bevel gear 603, a bidirectional threaded column 604, a transmission plate 605, a guide platform 606, an electric push rod 607, an iron lifting plate 608, a transmission rod 609, and an ejector 61. 0. A fixed column 611, a spring 612, a support rod 613, a support column 614, and a storage cavity 615 are connected to the base 1. A drive motor 601 is connected to one side of the base 1 via a storage cavity. The output end of the drive motor 601 is connected to a first bevel gear 602, and a second bevel gear 603 is meshed with the outer wall of the first bevel gear 602. A bidirectional threaded column 604 is welded inside the second bevel gear 603, and a transmission plate 605 is threaded to both sides of the middle of the bidirectional threaded column 604. A guide platform 606 is welded to the top of the transmission plate 605. The outer walls of the left mold 4 and the right mold 5 are both connected to the guide platform 606 by bolts. The outer wall of the guide platform 606... The guide platform 606 is equipped with an electric push rod 607, and the output end of the electric push rod 607 is connected to an iron lifting plate 608 via an electromagnet. The guide platform 606 is T-shaped. A transmission rod 609 is welded to one side of the top of the iron lifting plate 608, and an ejector 610 is connected to the top of the transmission rod 609. The ejector 610 is semi-circular. A fixed column 611 is slidably connected inside the iron lifting plate 608, and a spring 612 is sleeved on the outer wall of the fixed column 611. The iron lifting plate 608, the fixed column 611, and the spring 612 form an elastic telescopic mechanism. A support rod 613 is welded to the outer wall of the guide platform 606 on the side away from the electric push rod 607. A support column 614 is sleeved on the outer wall of the strut 613, and one side of the outer wall of the support column 614 is welded to the base 1; a storage cavity 615 is opened in the middle of the top of the base 1, and limiting cavities corresponding to the guide platform 606 are opened on both sides of the top of the base 1; the guide platform 606 is symmetrically distributed about the vertical center line of the base 1, and the outer walls of the bidirectional threaded column 604 are connected to the inner wall of the base 1 through bearing seats on both sides; fixed columns 611 are evenly distributed in the iron lifting plate 608, and movable cavities are opened at the bottom of the outer walls of the left mold 4 and the right mold 5, and forming cavities are opened at the top of the outer walls of the left mold 4 and the right mold 5; the guide platform 606 and the base 1 are slidably connected.

[0023] In specific implementation, during the production of sealing rings using a mold, after a single batch of sealing rings is formed, the electric push rod 607 is activated first. Since the output end of the electric push rod 607 is connected to the iron lifting plate 608, the extension of the electric push rod 607 will cause the iron lifting plate 608 to move upwards. Then, the upward movement of the iron lifting plate 608 will cause the transmission rod 609 to move upwards. Because the transmission rod 609 is connected to the ejector 610, the upward movement of the transmission rod 609 will cause the ejector 610 to move upwards as well. Furthermore, since the iron lifting plate 608 and the fixed column 611 are slidably connected, at this time, through the fixed column... The fixed column 611 guides the movement of the iron lifting plate 608, allowing it to move smoothly upwards. When the iron lifting plate 608 moves upwards, it compresses the spring 612, causing it to deform. Then, the spring 612 resets and assists the iron lifting plate 608 to move downwards. At this time, the ejector 610 moves upwards to eject the sealing ring, so that the sealing ring is no longer tightly attached to the mold. Because the ejector 610 is semi-circular, the contact area between the ejector 610 and the sealing ring is large when the ejector 610 is ejected, which makes the sealing ring bear force evenly when ejected, preventing it from deforming due to uneven force.

[0024] After the sealing ring is ejected from the left mold 4 and the right mold 5, the drive motor 601 is started. Since the output end of the drive motor 601 is connected to the first bevel gear 602, the start of the drive motor 601 will drive the first bevel gear 602 to rotate. Since the first bevel gear 602 and the second bevel gear 603 are meshed, the rotation of the first bevel gear 602 will drive the second bevel gear 603 to rotate. Then the rotation of the second bevel gear 603 will drive the bidirectional threaded column 604 to rotate. Since the bidirectional threaded column 604 is threadedly connected to the transmission plate 605, the rotation of the bidirectional threaded column 604 will cause the transmission plate 605 to move away from each other.

[0025] Because the top of the transmission plate 605 is connected to the guide platform 606, the movement of the transmission plate 605 will drive the guide platform 606 to move together. Since the transmission plate 605 is connected to the support rod 613, the support rod 613 slides along the support column 614, thereby limiting the movement of the transmission plate 605. Then, the movement of the guide platform 606 will drive the left mold 4 and the right mold 5 to move. At this time, the left mold 4 and the right mold 5 move away from each other, thereby causing the ejected sealing ring to quickly disengage from the mold. After that, the sealing ring falls into the storage cavity 615 under the action of gravity.

[0026] Next, the drive motor 601 is started to move the guide platform 606 closer to each other, so that the mold continues to produce the mold. Then, the sealing ring in the storage cavity 615 can be taken out by the push plate tool. The sealing ring can be taken out during the mold production, thus saving time and improving work efficiency. Moreover, it eliminates the need for workers to manually approach the mold to remove the parts, reducing the risk of accidents. Finally, when the sealing ring mold is used, it plays a role in facilitating the ejection and removal of parts and improving work efficiency.

[0027] In summary, when using this ejection anti-deformation sealing ring mold, the left mold 4 and right mold 5 are placed on top of the base 1 beforehand. Then, the raw material is introduced into the forming cavity of the mold, and the mold closing machine is started, causing the closing platen 2 to move the upper mold 3 downward until the upper mold 3 is in contact with the left mold 4 and right mold 5, thereby squeezing the raw material to form the desired sealing ring shape. This is existing technology and will not be elaborated on here. The ejector mechanism 6 moves the ejector 610 upward to eject the sealing ring, thereby making the sealing ring no longer tightly attached to the mold and ensuring that the sealing ring is evenly stressed during ejection, preventing deformation due to uneven stress. Subsequently, the left mold 4 and right mold 5 move away from each other, causing the ejected sealing ring to fall into the storage cavity 615. The sealing ring can then be removed from the storage cavity 615 during production, thereby saving time and improving work efficiency. The contents not described in detail in this description are existing technologies known to those skilled in the art.

[0028] Although the present invention 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 invention should be included within the protection scope of the present invention.
