In the present embodiment, die sleeve 4 is the cylinder of the die cavity 3 for being provided with upper and lower insertion, and the thickness of upper parallels 1 determines powder
The molding thickness of material（The length sum that original state seaming chuck thickness protrudes gripper shoe with push-down head deducts push-down head lower end distance
The height of plate upper surface is equal to the height of die cavity 3, and the thickness of upper parallels 1 determines the final molding thickness of powder, that is, designs thick
Degree）, upper parallels 1 uses in pairs, and using the upper parallels 1 of different-thickness the compressing of multi-thickness finished product is capable of achieving.
The automatic mould unloading mold use process of the present embodiment is as follows：
（1）It is die-filling：Powder to be pressed is homogeneously disposed in die cavity 3, the press-in die cavity 3 of seaming chuck 2, in the both sides of seaming chuck 2
Symmetrically placed upper parallels 1, the mould for assembling is placed on one-way press work top；
（2）Compacting：Start one-way press, press upper pressure head is moved down so as to press to seaming chuck 2, and seaming chuck 2 is continued into
In die cavity 3, meanwhile, support elastomer 5 to compress, die sleeve 4 is moved down, and in the presence of mould unloading elastomer 8, the side of push-down head 7 is persistently entered
Enter die cavity 3, realize that bi-directional synchronization is suppressed, until press upper pressure head and the rigid contact of upper parallels 1, push-down head 7 and the rigidity of base plate 11
Contact, the lower end of die sleeve 4 and the rigid contact of gripper shoe 9；At the end of compacting, the first snap fit 6 and the second snap fit card 17 are connected to into one
Rise, make die sleeve 4 link together with gripper shoe 9；
（3）Mould unloading：Release is moved on press upper pressure head, because die sleeve 4 is joined together with gripper shoe 9, now mould unloading bullet
Gonosome 8 progressively recovers deformation, persistently finished product is ejected into die cavity 3 by push-down head 7, treats that press upper pressure head takes off with mould seaming chuck 7
From, you can mould is taken out from compressor operation table top, finished product is taken away, the position that the second snap fit 17 protrudes gripper shoe 9 is pressed, the
One snap fit 6 departs from the second snap fit 17, and die sleeve 4 departs from gripper shoe 9, restPoses, repeat step（1）, implement again
It is compressing.
