Abstract
The utility model provides a die ejection device, and belongs to the technical field of die processing. The die ejection device comprises a sleeve. An ejection column is arranged in the sleeve, the lower end of the ejection column is connected with a linkage rod, and the linkage rod is connected with an ejection motor. Transverse holes are formed in the side wall of the sleeve, and clamping columns are connected inside the transverse holes in a sleeved mode. The ejection column is provided with grooves corresponding to the transverse holes in position, and the number of the grooves is the same as that of the transverse holes. The clamping columns are provided with protruding blocks, and the outer ends of the protruding blocks are connected with return springs in a sleeved mode. The die ejection device has the advantages that the clamping columns increase the friction force between a die base and a die and can clamp the die to the base well. After die processing is finished, the ejection motor can push the ejection column through the linkage rod and eject the die, then operating personnel can take the die down easily, and therefore the condition that the die adheres to the base excessively and can be not taken down can be avoided, and manpower consumption is reduced.
Description
Technical field
The utility model belongs to mold machining technology field, particularly a kind of mold liftout attachment.
Background technology
After contact lens completes polishing, staff need take off the mould that is fixed with contact lenses from mold base, in the time of polishing, due to higher rotating speed and friction, can produce certain heat, the heat producing can make mould and base generation blocking under warming, thereby mould is combined closely with base, is difficult for taking off.If operating personnel exert oneself too small, cannot transfer to mould, if exert oneself excessive mold damage likely again.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of mold liftout attachment, and this device can be by top lifting motor after polishing finishes, by mould jack-up.
Technical problem of the present utility model adopts following technical proposals to solve:
A kind of mold liftout attachment, comprises sleeve, establishes a fore-set in sleeve, and fore-set lower end links a trace, and the sidewall of sleeve is provided with transverse holes, is socketed with and holds post in transverse holes, and fore-set is provided with groove, and groove is identical with transverse holes position respective amount.Hold post and be provided with projection, projection outer end is socketed with return spring.Hold post outer end and establish a hemispherical projections, a conical projections is established in the inner, and the diameter of hemispherical projections and conical projections equals the diameter of transverse holes inwall.The length that holds post is greater than the degree of depth of transverse holes.In transverse holes, be provided with outer baffle block and internal stop, outer baffle block is located at return spring outer end, and internal stop is located at projection the inner.On trace, cover has ejector spring.Transverse holes is provided with at least 2.Trace is connected with top lifting motor.
The beneficial effects of the utility model are, hold post and have increased the frictional force between mold base and mould, mould can well be held on base.After Mould Machining, top lifting motor can promote fore-set by trace, and by mould jack-up, operating personnel just can take off mould easily afterwards.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
A kind of mold liftout attachment, comprises sleeve, is socketed with a fore-set 2 in sleeve 1, and fore-set 2 lower end chains are connected to trace 10, have 2 transverse holes 6 on the sidewall of sleeve 1, in transverse holes 6, are socketed with and hold post 3, and the length that holds post 3 is greater than the degree of depth of transverse holes 6.On fore-set 2, offer groove 11, groove 11 is identical with transverse holes 6 position respective amount.Holding post 3 outer ends is a hemispherical projections 13, and the inner is a conical projections 12, and the diameter of hemispherical projections 13 and conical projections 12 equals the diameter of transverse holes 6 inwalls.Hold post 3 hemispherical projections 13 and conical projections 12 between be installed on projection 14, projection 14 outer ends are socketed with return spring 4.In transverse holes 6, be installed on outer baffle block 8 and internal stop 9, outer baffle block 8 is installed in return spring 4 outer ends, and internal stop 9 is installed in projection 14 the inners.On trace 10, cover has ejector spring 5, and trace 10 is connected with top lifting motor.In the time there is no installation mold on mold base, fore-set 2 is due to the effect of ejector spring 5, and fore-set 2, by jack-up upwards, holds post 3 because the effect of return spring 4 can be contracted among transverse holes 6, the conical projections 12 that holds post 3 ends by top to groove 11.In the time that mould is arranged on mold base, fore-set 2 is pressed down, and fore-set 2 can push the conical projections 12 that holds post 3 ends, holds post 3 and is pushed up outside transverse holes 6, cause the conical projections 12 that holds post 3 front ends to be exposed to outside sleeve 1, and top is to the inwall of mould.Mould is better held.When completing after polishing, operating personnel can operate top lifting motor, and top lifting motor upwards promotes fore-set 2 by trace 10, hold post 3 and also retract gradually in transverse holes 6, so just can be by mould ejection.
