Cross screw and be fixed on the lower end of cover half fixed plate 26；The cavity 23 is arranged in the solid plate 25, the cavity
23 lower ends are provided with push piece plate 20, and the upper end of cavity 23 is provided with core 24, the cavity 23 and the shape of the core 24
Into the die cavity of plastic 22, the push piece plate 20 is arranged in a release fixed plate 19, the release fixed plate 19 and the dynamic model
Plate is connected by spring 17；Thread core 32, the formation of thread core 32 plastic 22 are provided with the release fixed plate 19
Internal thread, thread core 32 is arranged in the moving platen by fourth bearing 16, is provided with the thread core 32 big
Gear 14, the gear wheel 14 is provided with sprocket wheel 6 with setting the little gear 7 on central shaft 3 to coordinate on the central shaft 3, drive
Dynamic motor drives the central shaft 3 to rotate by the sprocket wheel 6；The upper end center of cover half fixed plate 26 is provided with centring ring
27, the centring ring 27 is connected with sprue 28, and the sprue 28 is connected by side gate road with the die cavity of plastic 22.When outer
When portion's power (motor) band movable sprocket 6 is rotated, the little gear 7 on central shaft 3 makees synchronous axial system, drives on thread core 32
Gear wheel 14 makees opposite direction motion, and now thread core 32 also makees equidirectional circular motion with gear wheel 14, is formed with plastic 22
Relatively rotate, so as to realize the automatic demoulding of screw thread.
Wherein, cooling water through hole is provided with the cavity 23 and the push piece plate 20, the cooling water through hole is with setting
The water nozzle 31 in the side of solid plate 25 is put to connect.
Wherein, guide pillar 21 is provided between the moving platen and the solid plate 25, the guide pillar 21 is described with being arranged on
The first guide pin bushing 33 on solid plate 25, and the second guide pin bushing 34 being arranged in the release fixed plate 19 coordinate.
Wherein, one end of the central shaft 3 is arranged on the moving clamping plate 2 by clutch shaft bearing 4, and the other end passes through the
Two bearings 8 are arranged in the moving platen；It is provided between the sprocket wheel 6 and the moving clamping plate 2 on packing ring 5, the sprocket wheel 6
