Summary of the invention
For the problems referred to above, the utility model provides a kind of cut-out mould of automobile engine exhaust system air outlet taper pipe shell, and it can guarantee to cut off the complete of rear upper half shell and lower half shell housing profile.
Its technical scheme is such, it comprises upper die structure and lower die structure, described upper die structure comprises cope match-plate pattern and fixed head, described fixed head is installed under described cope match-plate pattern, described lower die structure comprises lower bolster, installing plate, described lower bolster is installed on described installing plate by mould pin, described upper die structure and lower die structure are by slip independent pilot part guiding matched moulds, it is characterized in that: described upper die structure also comprises cut-out punch structure, described lower die structure also comprises workpiece positioning female die structure.
It is further characterized in that:
Described cut-out punch structure comprises holding pad, cuts off punch, described holding pad is installed on described fixed head below and is connected with described fixed head with unloading bolt by spring, and described cut-out punch is installed in described fixed head and is passed down through described holding pad;
Discharging guide pillar is also installed in described fixed head, in corresponding described discharging guide pillar position, described holding pad, has pilot hole, discharging guide pin bushing is installed in described pilot hole, described discharging guide column sleeve is loaded in described discharging guide pin bushing;
Described workpiece positioning female die structure comprises that locating piece, upper half shell cut off re-entrant mold mold insert, lower half shell cuts off re-entrant mold mold insert, described locating piece is installed on described lower bolster, described upper half shell cuts off re-entrant mold mold insert, lower half shell cuts off re-entrant mold mold insert and cuts off limit insert in described locating piece along correspondence respectively, workpiece upper half shell stub end limited block is installed in the horizontal left side of described locating piece, described workpiece stub end limited block in described cope match-plate pattern, is also provided with workpiece lower half shell stub end limited block by end locating piece limit mounting on described locating piece.
While adopting the utility model mould to carry out punching press cut-out to connecting the shell workpiece of expecting after one-body molded processing, workpiece is tightly pressed in locating piece by its holding pad, upper half shell cuts off re-entrant mold mold insert, lower half shell cuts off on re-entrant mold mold insert, and workpiece upper half shell stub end limited block, workpiece stub end limited block plays good position-limiting action to workpiece, therefore upper half shell after its cut-out that can effectively avoid causing because of workpiece positioning compression difficulty, it is wrinkling that lower half shell cuts off limit, the defects such as depression, guarantee accurate processing, thereby effectively reduce follow-up shaping manufacturing procedure, enhance productivity, and between fixed head and holding pad, be also connected with discharging guide pillar, and can further guarantee the reliable compression of holding pad to workpiece, thereby guarantee to cut off the accurate of the die-cut position of punch, prevent from cutting partially.
