Its main function is to prevent liquid, gas or solid particles from leaking out of the connection and prevent external impurities from entering the system, thereby ensuring the normal operation and safety of the equipment.

[0003] Among them, when the sealing ring is produced, a production mold is used to stamp the sealing ring to complete the molding of the sealing ring.

[0004] However, when the prior art is actually used, during the process of stamping the sealing ring using a production mold, since the sealing ring is directly stamped into the mold, after the stamping of the sealing ring is completed, the sealing ring is easily adsorbed by force inside the mold, resulting in cumbersome and inconvenient removal of the sealing ring.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. In the utility model, when the sealing ring material fills the upper cavity and the lower cavity and is pressed and formed under the action of the upper mold and the lower mold, the elastic convex strip will deform and shrink along the inside of the elastic groove during the pressing process to adapt to the deformation of the sealing ring material inside the upper cavity, and when the sealing ring is stamped and molded for demolding, the upper mold will move upward driven by the upper mold seat. When the upper mold moves upward, the elastic potential energy generated by the deformation and contraction of the elastic convex strip pushes the upper end of the sealing ring to move downward, so that the sealing ring stays at the upper end of the lower mold;

[0017] 2. The utility model also controls to open the electric telescopic rod when the sealing ring stays at the upper end of the lower mold.

[0024] An upper mold 6 is fixedly installed in the middle of the lower end surface of the upper mold base 1, and a pressing plate 7 is movably connected to the outer curved surface of the lower end of the upper mold 6. First limit slide bars 8 are fixedly installed on both sides of the upper end of the pressing plate 7, and there are six first limit slide bars 8, and each three first limit slide bars 8 form a group. Two groups of first limit slide bars 8 are symmetrically distributed on both sides of the upper end of the pressing plate 7. Limited sliding holes 9 are provided on both sides of the upper end of the upper mold 6, and the outer curved surface of the upper end of the first limit slide bar 8 is movably connected to the inner wall of the lower end of the limit slide hole 9. A support spring 10 is provided, and the upper top of the support spring 10 is fixedly installed at the lower end of the upper die seat 1, so that the support spring 10 cooperates with the first limiting slide bar 8 and the limiting slide hole 9 to elastically limit the pressing plate 7. The lower end surface of the upper die 6 is provided with an upper cavity 11 that matches the upper shape of the required production sealing ring, and the upper top of the upper cavity 11 is provided with an elastic groove 12, and the number of elastic grooves 12 is staggered and symmetrically distributed at the upper top of the upper cavity 11, and the inner wall of the elastic groove 12 is fitted and movably connected with an elastic convex strip 13;

[0025] A lower mold 14 is fixedly installed in the middle of the upper end surface of the lower mold base 2, and a lower cavity 15 matching the shape of the lower part of the required production sealing ring is opened at the upper end of the lower mold 14. The inner wall of the lower end of the lower mold 14 is fitted and movably connected with a stripping plate 16. The bottom support of the lower mold base 2 is fixedly installed with an electric telescopic rod 17, and the top telescopic part of the electric telescopic rod 17 is fixedly installed with a lifting plate 18.

[0026] Working principle: When in use, the utility model installs the upper die base 1 and the lower die base 2 with the external punching machine. When the upper die base 1 and the lower die base 2 are installed with the external punching machine, the raw material of the sealing ring to be produced is fed between the upper die 6 and the lower die 14. When the raw material of the sealing ring is fed between the upper die 6 and the lower die 14, the external punching machine is turned on by control. When the external punching machine is turned on, the upper die base 1 is driven by the punching rod 5 to perform a linear downward punching. When the upper die base 1 performs a linear downward punching, it drives the pressing plate 7 to perform a linear downward punching on the raw material of the sealing ring. Move and press, so that the sealing ring raw material remains fixed. When the pressing plate 7 moves and presses the sealing ring raw material downward in a straight line, the support spring 10 cooperates with the first limiting slide bar 8 and the limiting slide hole 9 to elastically limit and support the pressing plate 7. At the same time, when the upper die seat 1 performs a straight downward stamping, it will drive the upper die 6 and the lower die 14 to move and close the mold. When the upper die 6 and the lower die 14 move and close the mold, the sealing ring raw material fills the upper cavity 11 and the lower cavity 15 under the force of the upper die 6 and the lower die 14 closing the mold and is pressed into shape, thereby realizing the stamping and forming of the sealing ring;

[0027] At the same time, when the sealing ring material fills the upper cavity 11 and the lower cavity 15 and is pressed and formed under the force of the upper mold 6 and the lower mold 14, the elastic convex strip 13 will deform and shrink along the elastic groove 12 during the pressing process to adapt to the deformation of the sealing ring material inside the upper cavity 11. When the sealing ring is stamped and molded for demolding, the upper mold 6 will move upward under the drive of the upper mold base 1. When the upper mold 6 moves upward, the elastic potential energy generated by the deformation and contraction of the elastic convex strip 13 pushes the upper end of the sealing ring to move downward, so that the sealing ring stays at the upper end of the lower mold 14. When the ring stays at the upper end of the lower mold 14, the electric telescopic rod 17 is controlled to be turned on. When the electric telescopic rod 17 is turned on, it will drive the lifting plate 18 to move linearly up and down. When the lifting plate 18 moves linearly upward, it will drive the push rod 20 to move linearly upward. When the push rod 20 moves linearly upward, it will push the stripping plate 16 to move linearly upward. When the stripping plate 16 moves linearly upward, it will push the inner ring of the sealing ring at the upper end of the lower mold 14 upward, so that the sealing ring is separated from the loose upper end of the lower mold 14, thereby realizing the stamping molding of the sealing ring and facilitating the removal of the sealing ring.
