Frictional force is more than thrust and realizes self-locking, just can so withstand between lower platen.
The detailed process of above-mentioned time-delay mechanism is as follows：
This time-delay mechanism starts to act on material pressing core contact lower die, acts on to the completely separable end of upper and lower mould.During molding, on
Mould moves downward, and when upper mold nitrogen gas spring 11 and shoe contact, due to not starting to be molded, upper mold material pressing core 4 is located always
In release conditions, so can be contacted when sliding block slips into 4 insert of upper mold material pressing core, until blank holder 6 and upper mold seat 3 connect completely
When touching, part is in binder state, and at this moment nitrogen gas spring 11 is compressed to range (stage 1, referring to attached drawing 1).During shaping, on
Molding compound core 4 is in opposing stationary state, and upper mold and blank holder 6 move shaping relatively downward, at this moment the first sliding block 8 and pressure
Expect 18 relative motion of core insert, when complete shaping, 18 and first sliding block 8 of material pressing core insert completes relative motion, upper mold nitrogen
Spring 11 starts to discharge, and makes the first sliding block 8 is horizontal to slide, so as to withstand 4 insert of upper mold material pressing core (stage 2, referring to attached drawing 2).
When completing shaping.Blank holder 6 and upper mold movement upwards at the same time, because the first sliding block 8 withstands material pressing core insert 18, upper molding
Material core 4 can have been at impaction state and follow blank holder 6 to move upwards, before material pressing core and blank holder 6 separate, upper molding
Core 4 and blank holder 6 are expected all in opposing stationary state, so as to reach the effect of 4 release of delay upper mold material pressing core, are avoided
4 part of damage of upper mold material pressing core.When die sinking, upper mold seat 3 is initially separated with blank holder 6, and the release completely of nitrogen gas spring 11 is not made
For the 3rd sliding block 10, its return action of 17 component of tension spring makes the second sliding block 9 and the 3rd sliding block 10 be returned to original position (rank
Section 3, referring to attached drawing 3).There are oblique 5 ° of self-locking devices, normal pressure is realized in first sliding block 8 and material pressing core insert 18 inclined-plane because of between
The frictional force of generation is more than the thrust for playing rationed marketing 21, blank holder 6 and upper material pressing core is in opposing stationary state, until binder
Core discharges completely, and the first sliding block 8 is separated with material pressing core insert 18, and frictional force disappears, and playing 21 component of rationed marketing resets the first sliding block 8
To original position, so when 18 and first sliding block 8 of material pressing core insert separates, the effect of this time-delay mechanism terminates, and replys completely
To home position (stage 4, referring to attached drawing 4).
The process for stamping of the utility model time-delay mechanism mould, includes the following steps：
(1) by material pressing core insert lock on upper mold material pressing core, and the component in material pressing core insert is installed, nitrogen gas spring is pacified
Mounted in upper mold, the installation of upper mold is completed.
(2) by mechanism mounting assembly on blank holder.Slide and the first sliding block are first filled, is pacified according to the point empty position of die holder
Sliding assembly and guide plate are filled, then the first sliding block is transferred in slide.Install again and play rationed marketing component, then flanging is attached to bolt lock
On circle.Slide pedestal is installed on blank holder, tension spring component is assembled and is installed on by bolt on slide pedestal, tension spring, company
Extension bar and cover board are put into tension spring component, and the second sliding block is put into pedestal, and connecting rod is screwed into the second sliding block.Finally the 3rd sliding block is placed on
On second sliding block, ensure contact of incline plane, finally load onto slide cover board, ensure that the 3rd sliding block energy normal upright is oriented to.Complete flanging
The installation of Quan Shang time-delay mechanisms component.
(3) produced on the press apparatus of no blocking function, when part completes shaping, blank holder and upper mold seat at the same time to
Upper movement, this mechanism competence exertion time-lag action, so as to complete to produce.
(5) the good stamping parts of punching press is removed.
Above-described embodiment is only the preferred embodiment of the utility model, not limits the protection model of the utility model according to this
Enclose, therefore：The equivalence changes that all structures, shape, principle according to the utility model are done, should all be covered by the protection of the utility model
Within the scope of.
