For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of Zipper forming mould, comprise an ox head seat, to be installed on described ox head seat and the cooperatively interact mold and bed die and a shaping screw mechanism that arrange, travelling gear and drive link are equipped with in the top of described ox head seat, described shaping screw mechanism comprises upper end respectively with the first screw rod and second screw rod of a driven gear, described first screw rod is respectively provided with one first step trough above and below its driven gear, described second screw rod is respectively provided with one second step trough above and below its driven gear, in described first step trough and described second step trough, a needle bearing is all housed.
Further, the top of described first screw rod and the second screw rod is arranged with screw support assembly, and this screw support assembly comprises correspondence and is arranged at wear-resistant sleeve above each needle bearing, is arranged at the nut above each wear-resistant sleeve and is set in the semicircle positioning sleeve on each wear-resistant sleeve.
Further, described first screw rod and the second screw rod are also arranged with needle bearing fixed block, described needle bearing is fixedly installed in this needle bearing fixed block.
Further, the outside of described semicircle positioning sleeve is equiped with a positioning sleeve fixed block, and this positioning sleeve fixed block is provided with bolts assemblies hole, this bolts assemblies hole is equiped with one for regulating the adjustment pilot pin of positioning sleeve fixed block upper-lower position.
Compared to the prior art, the beneficial effect that the utility model produces is:
1, the utility model structure is simple, practical, by each correspondence on above-mentioned first screw rod and the second screw rod, two the first step troughs and two the second step troughs are set, and the needle bearing that fit on is suitable, utilize described needle bearing and screw rod to arrange in pairs or groups and form rotary locate mode of sliding, reduce the fretting wear of screw rod and bearing fixed block locating hole, make to bring up to original structure more than three times the service life of screw rod and bearing fixed block.
2, in the utility model, described screw support assembly comprises wear-resistant sleeve and semicircle positioning sleeve, utilize this wear-resistant sleeve and semicircle positioning sleeve with the use of, avoid the frictionalwear that screw rod is too much, and these parts can dismounting and change, thus be conducive to improving and extending service life of the present utility model, directly increase economic efficiency.
3, in the utility model, by arranging wear-resistant sleeve, semicircle positioning sleeve and regulating pilot pin, not only service life can be improved, and also manual fine-tuning is changed into by hammer in the position of length screw rod up and down fine setting, optimize location and regulative mode, screw rod is finely tuned more rationally accurately up and down, also makes produced product quality more stable, reduce the fault rate of mould, make frequency of maintenance reduce more than 50%.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of the mechanism of shaping screw described in the utility model.
Detailed description of the invention
Detailed description of the invention of the present utility model is described with reference to the accompanying drawings.
See figures.1.and.2.A kind of Zipper forming mould, comprise an ox head seat 1, a travelling gear 2 and drive link 3 are equipped with in the top of described ox head seat 1, to be installed on described ox head seat 1 two molds cooperatively interacted 4 and bed die 5 and to be located at mold 4, shaping screw mechanism 6 on bed die 5 mating surface, described shaping screw mechanism 6 comprises upper end and is with cogged first screw rod 60 and the second screw rod 61 respectively, the gear of described first screw rod 60 is equipped with two the first step troughs 600 up and down, the gear of described second screw rod 61 is equipped with two the second step troughs 610 up and down, at described first step trough 600 and described second step trough 610, a suitable needle bearing 7 is all housed, described first screw rod 60 and described second screw rod 61 upper surface toward part downwards and at the reserved segment distance of respective described needle bearing 7 part upwards, respective screw support assembly 8 is housed.By above-mentioned setting, utilize described needle bearing 7 to arrange in pairs or groups with screw rod and form rotary locate mode of sliding, reduce the fretting wear of screw rod and bearing fixed block locating hole, make bring up to original structure more than three times the service life of the first screw rod 60 and the second screw rod 61 and corresponding bearing fixed block.
