[0093] Specifically, the jaw driving member can be a cylinder connected with the second elastic jaw 16 to drive the second elastic jaw 16 to different positions. The jaw driving member can also be a cam 161 fixedly connected to the central fixed shaft 113 near the lower turntable 122. The second elastic jaw 16 is abutted on the cam 161 by a spring, and moves around the cam 161 with the rotation of the turntable set 12, so that the cam 161 drives the second elastic jaw 16. The second elastic jaw 16 includes a wedge-shaped sliding block 162 and two clamping blocks. The wedge-shaped sliding block 162 is connected to the lower turntable 122 by a guide rail and a sliding block, and moves along the axis direction of the lower turntable 122. The two clamping blocks are also connected to the lower turntable 122 and are divided into a left clamping block 166 and a right clamping block 167, which are located on both sides of the wedge-shaped sliding block 162 and are connected to the lower turntable 122 by a guide rail and a sliding block, and can move in a direction perpendicular to the movement direction of the wedge-shaped sliding block 162. The wedge-shaped sliding block 162 is provided with a cam follower 165 which is slidably connected to the cam 161. The left clamping block 166 and the right clamping block 167 are each provided with a cam follower 165 for abutting the two sides of the wedge-shaped sliding block 162. The wedge-shaped sliding block 162 is also provided with a spring connected between the wedge-shaped sliding block 162 and the lower turntable 122, and the spring is in a tension state. The two clamping blocks are also connected by a spring, so that the two clamping blocks have a tendency to move towards each other.

[0094] Further, the wedge-shaped sliding block 162 has a first sliding surface 163 and a second sliding surface 164 connected on both sides, and the distance between the two first sliding surfaces 163 is greater than the distance between the two second sliding surfaces 164. Understandably, the two clamping blocks abut from both sides of the wedge-shaped sliding block 162, and when the clamping blocks are located on the first sliding surface 163, the two clamping blocks do not clamp the rubber part, and when the clamping blocks are located on the second sliding surface 164, the two clamping blocks clamp the rubber part. Therefore, by driving the movement of the wedge-shaped sliding block 162, the position of the clamping block abutting the wedge-shaped sliding block 162 is changed, and the state of the second elastic jaw 153 clamping the rubber part is changed. The spring makes the two clamping blocks tightly abut the sliding surface.

[0095] By the embodiment, the core rod is detachably connected to the core rod positioning block 131, and when the compression mold set 200 is pressed downward, the core rod is separated from the clamping of the first elastic claw and moves vertically downward along the first station 001. When the lower turntable 122 moves, the cam 161 is fixed at the center fixed shaft 113 and does not move, the wedge-shaped sliding block 162 abuts against the cam 161 and moves in the radial direction, and when the cam 161 drives the wedge-shaped sliding block 162 to move outward, the two clamping blocks abut against the first sliding surface 163 and then move away, thereby releasing the clamping of the rubber part. Conversely, when the cam 161 drives the wedge-shaped sliding block 162 to move inward, the two clamping blocks abut against the second sliding surface 164 and then move toward each other, thereby clamping the opening of the rubber part. Thus, when the core rod is pressed into the rubber part, the opening of the rubber part can be fixed, and the position deviation of the elastic rubber part is prevented, so that the core rod cannot be pressed into the rubber part.

[0096] In combination Figures 1 to 12 , the present application proposes an embodiment, the compression mold set 200 includes a frame body 21, a pressing mechanism 23, a guide mechanism 22 and a jacking mechanism 24. The frame body 21 is connected to the machine table and located on one side of the turntable module 100. The pressing mechanism 23 is connected to the frame body 21, and the pressing mechanism 23 is located above the second station 002 and is used to drive the core rod to press into the rubber part. The guide mechanism 22 is provided with a third positioning groove and located on one side of the first station 001. The compression mold set 200 further includes a jacking mechanism 24, and the jacking mechanism 24 is connected to the machine table and located below the second station 002. The jacking mechanism 24 moves in the vertical direction and abuts against the turntable module 100. When the first station 001 is in the compression position, the core rod driving part 132 drives the core rod positioning block 131 to approach the compression mold set 200, so that the first positioning groove and the third positioning groove cooperate to form a guide channel

[0097] Specifically, the frame 21 is higher than the rotary table module 100, and the frame 21 is provided with a pressing mechanism 23 including a cylinder and a pressing block. The cylinder moves up and down and drives the pressing block to move vertically. The machine table below the pressing block is provided with a space, i.e., a hole connecting the space above the machine table and the inside of the machine table. The pressing mechanism is provided with a jacking mechanism 24 below the frame 21 or inside the machine table. The jacking mechanism 24 jacks up to abut against the rubber part positioning mechanism 14 in the vertical direction, or jacks up from the inside of the machine table through the space to abut against the rubber part positioning mechanism 14 in the vertical direction, so as to prevent the rubber part positioning block 141 from colliding with the machine table when the pressing module 200 is pressed down, thereby preventing the machine table or the rubber part positioning block 141 from being damaged. The frame 21 is further provided with a guide mechanism 22, and the third positioning groove of the guide mechanism 22 is the third station 003. The jacking mechanism 24 includes a jacking cylinder 241 connected to a driving plate 242. The driving plate 242 has an inclined surface, and a roller 243 is slidingly connected to the inclined surface. A supporting plate 244 is rotationally connected to the roller 243 and moves in the vertical direction, and a return spring is further arranged therein. The jacking cylinder 241 drives the driving plate 242 in the horizontal direction, controls the movement of the roller 243 on the inclined surface, and thereby controls the upward or downward movement of the supporting plate 244.

[0098] Further, the cross section of the first station 001 is semicircular and matches the size of the core rod, and the cross section of the third station 003 is also semicircular and matches the size of the core rod. The core rod positioning block 131 and the guide mechanism 22 can be combined, i.e., the first station 001 and the third station 003 can be enclosed to form a guide channel, which is a cylindrical channel matching the size of the core rod to guide the vertical movement of the core rod.

[0099] Through the embodiment, when in the second position, the cylinder pushes the core rod positioning block 131 to move outward in the radial direction of the rotary table 121, and the core rod positioning block 131 and the guide mechanism 22 are combined to wrap the core rod. The second elastic clamp jaw 16 clamps the opening of the rubber part, and at this time, the core rod is located above the second station 002, i.e., above the opening of the rubber part. The pressing mechanism 23 presses down, drives the core rod downward and away from the first elastic clamp jaw 15, the core rod moves downward, the jacking mechanism 24 moves upward to abut against the rubber part positioning mechanism 14, so that the rubber part positioning mechanism 14 has an upward force, and the two move relative to each other to press the core rod into the rubber part from the opening of the rubber part, and then the jacking mechanism 24 and the pressing mechanism 23 reset to make the core rod positioning mechanism 13 disengage from the guide mechanism 22. The rotary table module 100 rotates to drive the station to enter the next position.

[0107] Through the embodiment, the end cover feeding mechanism 31 first arranges a stack of randomly stacked end covers in order and transports them to the end cover distributing mechanism 32. The end cover distributing mechanism 32 takes one of them out to expose the outer edge surface of the end cover.
