[0041] Working principle:
[0042] When it is necessary to eject the finished polyurethane carbon fiber composite material, first turn on the switch, the motor 26 starts working, drives the first rotating rod 31 to rotate, and then drives the first threaded rod 32 to rotate. Under the action of the thread, the first screw sleeve 33 is driven to move synchronously, and then the first connecting rod 34 is driven to move synchronously, and then the ejector rod 35 is moved synchronously. When the ejector rod 35 moves, the first moving rod 53 is moved synchronously inside the fixed seat 54, realizing the limiting effect on the ejector rod 35, thereby improving the stability of the device. When the first moving rod 53 moves inside the fixed seat 54, the first slider 55 is moved synchronously inside the first slide groove 56, realizing the limiting effect on the first moving rod 53, thereby improving the stability of the device. The stability of the position is ensured, and then the top template 36 is driven to move synchronously, driving the polyurethane carbon fiber composite material to be ejected. At the same time, under the action of the teeth, the second rotating rod 37 is rotated, thereby driving the third rotating rod 38 to rotate, and then the second threaded rod 39 is rotated. Under the action of the thread, the second screw sleeve 41 is driven to move. Under the action of the first limiting block 59 and the first limiting groove 61, the second screw sleeve 41 is prevented from following the second threaded rod 39 to rotate synchronously under the action of the thread, thereby driving the third threaded rod 47 to move synchronously. At the same time, the fourth rotating rod 42 is rotated, and under the action of the teeth meshing, the fifth rotating rod 43 is driven to rotate, and then the sixth rotating rod 44 follows the synchronous rotation. When When the second connecting rod 45 moves inside the sixth rotating rod 44, the second slider 57 moves synchronously inside the second sliding groove 58, realizing the limiting effect on the second connecting rod 45, improving the stability of the device, and under the meshing action of the teeth at the bottom end of the second connecting rod 45, driving the seventh rotating rod 46 to rotate, and finally driving the third threaded rod 47 to rotate synchronously. Under the action of the thread, the third screw sleeve 48 moves, driving the third connecting rod 49 to move synchronously, and finally driving the limiting plate 51 to move, clamping the polyurethane carbon fiber composite material, so that the polyurethane carbon fiber composite material can be clamped and ejected synchronously when ejecting the injection cavity, avoiding shaking and falling of the object when ejecting. During extrusion injection molding, the support rod 6 6 moves downward, and the support rod 66 moves inside the second fixed rod 67. At this time, the second spring 75 is squeezed, and the second spring 75 is elastically deformed, exerting a reaction force on the lower template 25 to keep the device stable. When the lower template 25 vibrates and moves downward, under the action of the movable shaft, the rotating plate 68 rotates, driving the moving block 71 to move, thereby squeezing the first spring 74. The first spring 74 is elastically deformed, exerting a reaction force on the moving block 71 to keep the moving block 71 balanced, thereby keeping the device stable. When the moving block 71 moves, the third slider 72 moves synchronously inside the third slide groove 73, realizing the limiting effect on the moving block 71, thereby improving the stability of the device. The operation is now complete.
