[detailed description of the invention]
Describe the present invention below in conjunction with accompanying drawing:
The present invention can solve the inner back-off depanning of circular product 7, when insufficient space.Existing mold, can not depanning smoothly when interiors of products has back-off 71, namely can not make the product that there is back-off inside.
As shown in the figure, a kind of special dies structure, the shaping depanning of circular product 7 of back-off is had for inside, include the interior profiled member 1 coordinating shaped article bottom and inside together, be enclosed within the middle profiled member 2 outside interior profiled member 1, be enclosed within the outer profiled member 3 outside profiled member 2, described interior profiled member 1 upper end is provided with the compacted under groove 11 of shaping circular product bottom and the back-off forming tank 12 of the inner back-off of shaping circular product, have above back-off forming tank 12 and contact spacing lower limit portion 13 with middle profiled member 2, described middle profiled member 2 upper end is provided with the upper limit portion 21 contacted with lower limit portion 13, described outer profiled member 3 is provided with the thread forming portion 31 of shaping circular product internal whorl, at interior profiled member 1, middle profiled member 2, the top of outer profiled member 3 is provided with the upper profiled member 4 of shaping circular product 7 top and outer shape.
The lower end of described interior profiled member 1 is provided with fixed part 14, fixed part 14 is provided with inwardly protruded spacer pin 15, the lower end of described middle profiled member 2 is provided with sliding tray 22 that is upper and lower in spacer pin 15 position and that rotate, described sliding tray 22 include middle profiled member 2 can be made to move up and down slide up and down groove 221, and the rotational slide groove 222 that middle profiled member 2 is rotated.
The lower end of described outer profiled member 3 is provided with the first spiral 32, driving cog gear member 5 is had in described outer profiled member 3 outer cover, described driving cog gear member 5 is provided with the second spiral 51 matched with the first spiral 32, described driving cog gear member 5 lower end is provided with gear part 52, is provided with to be meshed with gear part 52 and can the gear bar 6 that rotates of driven gear portion 52 on the side of driving cog gear member 5.
The lower end of described middle profiled member 2 is also provided with the pallet 23 held driving cog gear member 5 and driving cog gear member 5 is up moved with middle profiled member 2.
After circular product 7 is shaping, dynamical system up push up in profiled member 2, the groove 221 that slides up and down of middle profiled member 2 moves up and down along spacer pin 15, the pallet 23 of middle profiled member 2 also props up driving cog gear member 5 simultaneously, make it up move together, drive outer profiled member 3 up to move together, middle profiled member 2, outer profiled member 3 make circular product 7 up move and be separated with interior profiled member 1 simultaneously, now, the back-off forming tank 12 that the back-off 71 limiting circular product 7 rotates also is separated with circular product 7, then, dynamical system continue up top in profiled member 2, the rotational slide groove 222 of middle profiled member 2 rotates along spacer pin 15 and moves up and down, gear bar 6 rotates to the direction of setting simultaneously, namely be with nutating gear part 5 outside profiled member 3 rotate, the mutually external profiled member 3 of driving cog gear member 5 is moved upward, make pallet 23 not be transmitted gear member 5 to limit, namely outer profiled member 3 can not move upward, outer profiled member 3 is under the effect restriction of outside miscellaneous part, not rotatable, realize the smooth depanning of spiral part in circular product 7, in this process, gear bar 6 is highly constant in vertical height, driving cog gear member 5 can move upward one end distance, should ensure that the tine length S of gear bar 6 is more than or equal to the tine length L of driving cog gear member 5 and the ultimate range sum of up moving, ensure that two gears can not landing.
