Fig. 2 is the structural representation of the first screw thread core pulling mechanism in the utility model.
Fig. 3 is the structural representation of the second screw thread core pulling mechanism in the utility model.
Detailed description of the invention
The utility model preferred embodiment is provided, to describe the technical solution of the utility model in detail below in conjunction with accompanying drawing.
As shown in Figure 1 to Figure 3, the utility model injection mold screw thread core pulling device comprises the first screw thread core pulling mechanism 1, second screw thread core pulling mechanism 2, 3rd screw thread core pulling mechanism 3, top mold frame 4, lower mold holder 5, chain 6, oil cylinder 7, the first screw thread core pulling mechanism 1 comprises the first gear 11, first threaded mold core 12, the structure of the first rotating shaft 13, second screw thread core pulling mechanism 2 is identical with the structure of the 3rd screw thread core pulling mechanism 3, and the second screw thread core pulling mechanism 2 and the 3rd screw thread core pulling mechanism 3 all comprise the second gear 21, 3rd gear 22, 4th gear 23, second rotating shaft 24, tooth bar 25, second threaded mold core 26, first screw thread core pulling mechanism 1 is arranged in top mold frame 4, the second screw thread core pulling mechanism 2, 3rd screw thread core pulling mechanism 3 is all between top mold frame 4 and lower mold holder 5, and the first gear 11 is connected by chain 6 with between oil cylinder 7, and the first threaded mold core 12 and the first gear 11 are all arranged in the first rotating shaft 13, the second gear 21, 3rd gear 22 is all arranged in the second rotating shaft 24, and the second gear 21 engages with tooth bar 25, and the 4th gear 23 engages with the 3rd gear 22, and the 4th gear 23 is connected with the second threaded mold core 26.
Tooth bar 25 is connected with a rack support 27, and one end and the lower mold holder 5 of rack support 27 are fixed.Rack support 27 pairs of tooth bars 25 position, and prevent tooth bar 25 from offseting.
The size of the 3rd gear 22 is greater than the size of the 4th gear 23, the size of the second gear 21, so conveniently drives.
After injection mo(u)lding completes, die sinking predetermined stroke, the action of loosing core of the first screw thread core pulling mechanism of front mould starts, and by oil cylinder by chain-driving first pinion rotation, the first gear driven first threaded mold core rotates in the other direction by screw thread and exited action of loosing core.First screw thread core pulling mechanism is loosed core after action, the normal die sinking of front and back mould, by rack drives second gear, the 3rd gear, the 3rd pinion rotation of front mould, drive the second threaded mold core to exit by screw thread rotation in the other direction action of loosing core by gear simultaneously.Product takes out the normal matched moulds of rear mold, and all threaded mold cores, in oil cylinder and rack drives Regression original position, carry out time circulation of next mould and automatically produce.The utility model realizes screw thread automatic core-pulling, saves and manually looses core, and saves cost, and product quality is secure and product yield stable, and Machine automated injection moulding is produced, and raises the efficiency.
Above-described specific embodiment; the technical problem of solution of the present utility model, technical scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
