the bottom of the extrusion sleeve 42 is provided with two annular grooves, the top of the bottom plate 2 is provided with an annular bulge corresponding to the position of the annular groove on the extrusion sleeve 42, and the extrusion sleeve 42 is matched with the bottom plate 2 to extrude and shape the sealing ring.

the outer side surface of the lower end of the sliding column 51 is symmetrically provided with lower pressure rods 511, the positions of the lower pressure rods 511 correspond to the positions of the grooves above the extrusion sleeve 42 one by one, the bottom of the lower pressure rods 511 is provided with balls, the lower side wall of the annular groove of the extrusion sleeve 42 is provided with semicircular roller grooves, when the sliding column 51 moves downwards, the lower pressure rods 511 can drive the extrusion sleeve 42 to move synchronously, when the sliding column 51 rotates, the balls on the lower pressure rods 511 can roll in the roller grooves arranged in the annular groove of the extrusion sleeve 42, and when no external force is applied to the extrusion rod 7, the restoring force of the extrusion elastic rod 41 drives the sliding column 51 to return to the initial position through the lower pressure rods 511.

In addition, the invention adopts the method for extruding and forming the sealing ring by the automatic compression forming machine, and the method comprises the following steps:

The first step is as follows: placing a sealing ring: placing the seal ring cut to size on top of the base plate 2 so that the seal ring is directly below the sliding post 51;

The second step is that: and (3) extruding a sealing ring: the right end of the extrusion rod 7 is manually pressed down, the rolling wheel 72 can roll on the top of the bearing plate 521, and the rolling wheel 72 can be always attached to the bearing plate 521 under the connection effect of the hinge, so that the bearing plate 521 can stably transmit the downward pressure to the sliding column 51;

the third step: cutting a sealing ring: when the sliding column 51 is pressed down by the extrusion rod 7 and contacts with the bottom plate 2, the pressing block 54 can move upwards, the conical structure of the pressing block 54 can drive the scraper 56 to extend out through the scraper column 57, and then the scraper 56 can perform slotting action on the inner side surface of the sealing ring by manually grasping a handle on the sliding column 51 to rotate the sliding column anticlockwise;

The fourth step: and (3) extruding a sealing ring: the pressing rod 511 can drive the extrusion sleeve 42 to synchronously move when the sliding column 51 is contacted with the bottom plate 2, so that the extrusion mechanism 4 is matched with the bottom plate 2 to complete the extrusion molding operation of the outer end of the sealing ring;

the fifth step: retraction of the sliding post 51: after the sealing ring is grooved, the extrusion rod 7 is manually lifted and the sliding column 51 is rotated to the initial position, the scraper 56 can return to the initial position under the action of the return spring 58, and the restoring force of the extrusion elastic rod 41 drives the sliding column 51 to return to the initial position through the lower compression rod 511;

And a sixth step: collecting a sealing ring: and taking the extruded and cut sealing ring down from the bottom plate 2, and repeating the steps to complete the circular extrusion operation of the sealing ring.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are given by way of illustration of the principles of the present invention, and that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims. The scope of the invention is defined by the appended claims and equivalents thereof.
