Please refer to Fig. 1, Fig. 2 and Fig. 3 to illustrate, the purpose of this utility model is to provide a kind of worm screw mould structure, described worm screw mould structure comprises from top to down: the first template 100, front template 200, front cavity 210, rear cavity 310 and rear pattern plate 300, described front cavity 210 and described rear cavity 310 are by mold cavity forming worm screw plastic cement products 10, and described worm screw mould structure also comprises runner plate 400, front mould mold insert 500, rotating mechanism and deduction 900.
Described runner plate 400 is arranged in described first template 100, described front mould mold insert 500 is arranged in described front template 200, the upper end of described front mould mold insert 500 connects described runner plate 400, the lower end of described front mould mold insert 500 and described front cavity 210 upper end adaptation, described worm screw mould structure also comprises front template 230, described front moulded board 230 to be arranged in described front template 200 and to be positioned at the die joint place of described worm screw mould structure, described front moulded board 230 is sheathed on described front cavity 210, described front template 200 top groove 220 is provided with solid plate (not shown), described front template 200 and described solid plate are screwed by plug and 240 to fix, described front mould mold insert 500, front cavity 210 and rear cavity 310 main body are hollow cylinder.
Described rotating mechanism comprises driver element, gear unit, fixed mount 600, described driver element is arranged at the outside of described worm screw mould by described fixed mount 600, described gear unit is arranged in the groove 220 offered on described front template 200 top, described driver element and described gear unit are connected with a joggle, thus for driving described gear unit to rotate, described gear unit drives described front cavity 210 close to described front mould mold insert 500, refer to Fig. 4 and Fig. 5 to illustrate, described driver element comprises motor 700 and is arranged at the gear 720 on its rotating shaft 710, described motor 700 is AC electrical motor, described gear unit comprises the first gear train and the second gear train, described first gear train comprises gear shaft and sheathed gear 800 thereon, 810, 820, described second gear train comprises gear 830, 840 and along the outward extending tube-in-tube structure of its body, described tube-in-tube structure is sheathed in described front cavity 210, gear 810 in described first gear train, 820 with described second gear train in gear 830, 840 intermesh, ball 860 is provided with between described tube-in-tube structure and described front cavity 210.
One end of described deduction 900 is fixed on outside described front template 200, and the other end is fixed on outside described rear mold 300 plate, and described deduction 900 is for pinning described front template 200 with described rear pattern plate 300.
Refer to Fig. 2 to Fig. 6 to illustrate, the utility model is when die sinking, first the colloid of melting is by a some glue mouth 20, runner after front mould mold insert 500 and front cavity 210 enter die cavity, complete filling pressurize in injection machine, after cooling curing, because injection machine pulls die sinking, under the effect of pull bar 40, runner ejection plate 50 and the first template 100 are opened, and realize first time die sinking, the solidifying material of this time point glue mouth 20 adds about 30mm at the total length in die sinking direction, and die sinking distance is approximately about 130mm.
Secondly, described worm screw mould structure is opened between top clamping plate 60 and runner ejection plate 50, is now controlled by banking pin 70, realizes second time die sinking, and die sinking distance is about 9mm.
Then, due to plug screw 240 fixation, first template 100 and front template 200 are opened, first template 100 drives front mould mold insert 500 to move to the direction away from die cavity by runner plate 400 simultaneously, machine Control system part starts for motor 700 therewith, thus driving the gear 720 on its rotating shaft 710 to rotate, gear 720 is driven gear 800, gear 810 successively, and gear 830,820,840 moves, gear shaft starts to rotate simultaneously, when rotating about 23mm of arriving, (length adjustment according to product) machine Control system energize portions stops, in the process, because ejector sleeve 80 in rear pattern plate 300 is provided with ejector sleeve briquetting 81 away from one end of die cavity, therefore worm screw plastic cement products 10 can be stoped motionless, therefore by ball 860 and gear 830, (described ball 860 prevents gear 830 to the rotatable engagement of 840 simultaneously, skidding between 840 and front cavity 210), the front cavity 210 of the threaded portion of shaping described worm screw plastic cement products 10 can be rotated near front mould mold insert 500, until coordinate with the lower end of described front mould mold insert 500, now worm screw plastic cement products 10 exits the die cavity in front cavity 210, thus complete the die sinking of third time.
Finally, under the effect of deduction 900, worm screw plastic mould is opened between front template 200 and rear pattern plate 300, thus realize the 4th die sinking, meanwhile injection machine promotes lower liftout plate 91, promote upper ejector plate 92 by lower liftout plate 91 again, thus drive ejector sleeve 80 to be ejected by worm screw plastic cement products 10 on promotion ejector sleeve thimble, therefore to complete a shot shaping for the utility model.
The depanning of the utility model worm screw plastic mould is stablized, ensure that the precision of worm screw plastic cement products 10 to greatest extent, shorten whole injection cycle, save injection moulding cost, and structure of the present utility model is relative to relatively simply compact existing technology, there is stronger versatility, be applicable to promotion and application widely.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
