[0024] Two rear end force blocks are arranged on the rear end limit plate 3, a rotating cylinder 14 is arranged on the upper rear end force block 13, a transverse limit plate 10 is arranged between the rear end limit plate 3 and the vertical limit plate 9, and the transverse limit plate 10 is used to limit the overall transverse movement of the winding mold 23 and the wire rope vibration isolator 24.

[0025] The guide rail 5 , the slide block 6 and the power transmission block 7 enable the piston rod in the cylinder 8 to transmit the force energy horizontally to the ejection plate 22 around the mold.

[0026] The vertical limiting plate 9 is used to ensure that the ejection plate 22 of the winding mold can normally apply a horizontal force to the ejection plate 231 in the middle of the winding mold 23.

[0027] The rotary cylinder 14 is installed on the rear end force block so as to adapt to different sizes and models of wire rope vibration isolators 24 and their winding molds 23. There are multiple mounting holes on the rear end limit plate 3 for the rear end force block to be installed according to the needs, so as to adapt to different sizes and models of wire rope vibration isolators 24 and their winding molds 23.

[0028] Specifically, there are four threaded tie rods 4, which are respectively arranged at the four corners of the cylinder mounting plate 2 and the rear end stop plate 3, one end of the threaded tie rod 4 is connected to the cylinder mounting plate 2, and the other end is connected to the rear end stop plate 3. The four threaded tie rods can make the rear end stop block move vertically relative to the bottom plate 1 so as to adapt to wire rope vibration isolators 24 and winding molds 23 of different sizes and models.

[0029] The guide rail 5 is arranged between the cylinder mounting plate 2 and the vertical limiting plate 9 . The guide rail 5 is installed on the guide rail mounting plate 11 . The guide rail mounting plate 11 is arranged on the upper surface of the base plate 1 .

[0030] A hand valve 12 and a pneumatic manual valve 15 are provided on the lower surface of the bottom plate 1 . The hand valve 12 is used to control the extension and retraction of the piston rod of the cylinder 8 , and the pneumatic manual valve 15 is used to control the rotation and downward pressure of the piston rod of the rotary cylinder 14 .

[0031] The rotary cylinder 14 is provided with a rocker arm 16 and a pressure rod 17, one end of the rocker arm 16 is connected to the piston rod of the rotary cylinder 14, and the other end is connected to the pressure rod 17, and the pressure rod 17 applies vertical pressure to the wire rope isolator 24 located below it. As an embodiment, the surface of the pressure rod 17 has threads, and when it is necessary to eject the ejection plate 231 in the winding mold 23, the rocker arm 16 rotates to a position parallel to the length of the wire rope isolator 24, and then pressure is applied through the pressure rod 17, and the pressure rod 17 contacts the wire rope isolator 24 or is threadedly connected to the threaded hole on the wire rope isolator 24, which can effectively prevent the ejection plate 231 of the winding mold 23 from tipping backward after being stressed.

[0032] There is a gap between the two rear end force bearing blocks on the rear end limiting plate 3 that only allows the ejection plate 231 to pass through, and a hole is provided in the middle portion of the rear end limiting plate 3 that allows the ejection plate 231 to pass through.

[0033] There are two transverse limit plates 10 , which are respectively arranged on transverse limit mounting plates 18 , which are arranged on supporting plates 19 , which are arranged on bottom plate 1 .

[0035] The bottom surface of the bottom plate 1 is provided with four foot cups 20 and two hexagonal handles 21, and the hexagonal handles 21 are used to control the lifting and lowering movement of the support plate 19 to adapt to molds of different heights. The arrangement of the support plate 19 and the hexagonal handles 21 enables the mold ejection mechanism of the utility model to adapt to wire rope vibration isolators 24 and their winding molds 23 of different sizes and models.

[0036] like Figure 2 As shown, the mold 23 includes an upper clamping plate 232, a lower clamping plate 233 and a plate to be ejected 231 located therebetween. The upper and lower surfaces of the upper clamping plate 232 and the lower clamping plate 233 are both provided with grooves, and the wire rope isolator 24 is clamped in the grooves of the upper clamping plate 232 and the lower clamping plate 233.

[0037] like Figure 3 As shown, during operation, the assembly of the winding mold 23 and the wire rope vibration isolator 24 is placed between the vertical limit plate 9 and the rear end force block, and the two hexagonal handles 21 are adjusted at the same time to realize the lifting and lowering of the support plate 19, so that the ejection plate 231 in the winding mold 23 is adjusted to be on the same horizontal plane as the winding mold ejection plate 22, and the pneumatic manual valve 15 is used to control the rotation and downward pressure of the piston rod of the rotating cylinder 14, and the pressure rod 17 exerts pressure on the wire rope vibration isolator 24 and the winding mold as a whole. After the vertical pressure is applied, the piston rod of the cylinder 8 is controlled to extend by the hand valve 12, and a horizontal force is applied to the ejection plate 231 through the mold ejection plate 22, so that the ejection plate 231 is ejected and separated from the upper clamping plate 232 and the lower clamping plate 233 in turn through the gap between the rear end force blocks and the holes on the rear end limit plate 3. After the ejection plate 231 is ejected, the upper clamping plate 232 and the lower clamping plate 233 can be easily removed from the wire rope vibration isolator 24.
