Detailed Description

The invention will be further explained with reference to the following figures and examples:

referring to fig. 1-7, in the axle housing half shell forming stamping die, a lower base 1 is provided with a lower die core 2 mounting groove in the lower base 1, a lower die core 2 matched with an axle housing inner cavity is fixedly mounted in the lower die core 2 mounting groove, and the lower die core 2 comprises a first side die 9, a second bottom die 10 and a third side die 11;

upper base 4, set up the mold core mounting groove in upper base 4, fixed mounting has and axle housing outer wall assorted last mold core in the last mold core mounting groove, set up a plurality of spring holes in upper base 4, be connected with reset spring 5 in the spring hole, go up in the mold core set up with spring hole assorted step hole, swing joint has depression bar 6 down in the step hole, reset spring 5 butt is on depression bar 6 down.

The utility model discloses the process is as follows when using, assemble this stamping die earlier, specifically when assembling, through lower mold core 2 installation groove installation lower mold core 2 on lower base 1, install the mold core through the last mold core installation groove of upper base 4, wherein, in upper base 4 because install reset spring 5 through the spring hole, reset spring 5 extrudes with lower depression bar 6 in the last insert mutually, when reset spring 5 extrudes depression bar 6, lower depression bar 6 will expend the upper mold core, when shaping the axle housing, place panel on lower mold core 2 first, then upper base 4 drives the upper mold core and moves down, when upper base 4 moves down, lower depression bar 6 on it will contact panel earlier, after depression bar 6 and panel contact, can play the effect of location panel, do not walk the material when guaranteeing panel shaping, lower depression bar 6 is when with the panel contact, because reset spring 5's effect, lower depression bar 6 will retract, when guaranteeing to go up mold core and 2 compound dies of lower mold core, shaping axle housing that can be accurate.

Further, the first side die 9, the second bottom die 10 and the third side die are respectively combined by a plurality of insert monomers 3, and the upper die core is also formed by combining a plurality of insert monomers 3. Specifically, in order to make the utility model discloses a mold core when wearing and tearing appear or damage, can be more convenient change or maintain, first side mould 9, second die block 10 and third side mould are made up the concatenation by a plurality of monomer 3 of inserting, and on the same principle, go up the mold core and also make up the concatenation by a plurality of monomer 3 of inserting.
