Description
Technical field
The utility model relates to extrusion die field, the screw-type of espespecially a kind of aluminum profile extrusion die inlays cored structure.
Background technique
Previous extruding die for aluminum shaped material divergent die, design scheme are all to make two-piece-dress and (be divided to upper mold main mould body lower die two
Part) design, wherein core portion is in upper mold main mould body, and existing design processing scheme is exactly mold core and upper mold main mould body main mould
Body is disjunctor, and such design processing scheme is exactly difficult processing so that in place, especially electric spark process loses material guide groove and clear mould
Empty knife, has mold core to block under core, guarantees to stamp lower empty knife and material guide groove in the case where not hurting mold core again, becomes some and need to add
The part of work becomes dead angle position.Due to processing mold not in place, upper machine die trial qualification rate is low, and can generate pressure mistake
Greatly, the phenomenon that mold core collapses mould is easy to appear in extrusion process.
Therefore, the more complicated aluminium profile product of some structures, intermediate centered multiplexing head mold, starts using " edge
Core " technology exactly splits mold core and main mould body to process, and such processing method enables each position all be easily worked
Position.Mold core is inlayed into main mould body again later etc. processing, is combined into one.
But the design scheme of this three-piece is knife neck bit position empty under mold core to be lengthened to do, because of core portion
It increases, swing will be easy to produce in use process, lead to the inclined wall of profile wall thickness, so using unstable.

Laterally circumference is equipped with external screw thread to bar, and the inner wall of the cyclic annular edge core is equipped with internal screw thread corresponding with external screw thread, the upper mold master
The periphery that die body end face is located at screw rod offers locating slot, and the one side that the cyclic annular edge core is engaged with upper mold main mould body is equipped with and determines
The corresponding positioning protrusion of position slot, in the side of screw rod, simultaneously screw thread screws the cyclic annular edge core retainer plate, and the positioning protrusion of cyclic annular edge core
It is stuck in the locating slot of upper mold main mould body.
It specifically, further include positioning pin, the cyclic annular edge core is provided in the axial direction with and positions with screw flight junction
Corresponding location hole is sold, the positioning pin is plugged in positioning hole.
Specifically, threadingly junction offers v-depression to the outer end face of the cyclic annular edge core, and the v-depression uses
It freezes and fills and leads up.
Specifically, the length of the cyclic annular edge core and internal screw thread is 68.
Specifically, the side that the upper mold main mould body is located at screw rod is additionally provided with axial raised secondary mold core.
The utility model has the beneficial effects that: the mold core of upper mold use split-type design, ring-type edge core by screw thread with
Screw rod is fixedly connected, and keeps engagement secured；And cyclic annular edge core, when being set on screw rod, the positioning protrusion on ring-type edge core is just clamped
In the locating slot of upper mold main mould body, the soundness of cyclic annular edge core and screw rod is further enhanced, cyclic annular edge is effectively prevented
Core is eccentric, so that extrusion die is not easy to swing in use, the problem of avoiding profile inclined wall, ensure that the stabilization used
