Description

Novel anti-the flying of die casting expects exhaust block
Technical field
The utility model relates to die casting technical field, and specifically novel anti-the flying of a kind of die casting expects exhaust block.
Background technology
Generally all have exhaust block in die casting, for the exhaust of mold cavity, but disclosed most of exhaust block is all the future development towards exhaust effect at present.But because the structure of exhaust block itself can not be sufficiently large, make its envelope charge level near charging aperture less, be difficult to bear the type power that rises that aluminium alloy enters exhaust block, exhaust block easily produces and flies material, thus damage exhaust block and affect casting quality.
Utility model content
The utility model, for above-mentioned Problems existing, provides novel anti-the flying of a kind of die casting to expect exhaust block.
The utility model for achieving the above object, takes following technical scheme to be achieved:
Novel anti-the flying of a kind of die casting expects exhaust block, be made up of embedding cover half exhaust block and moving die exhaust block, the exhaust indent that the one side that described cover half exhaust block is relative with moving die exhaust block is respectively arranged with exhaust projection and matches with exhaust raised profile, forms exhaust passage between described exhaust projection and exhaust indent; Described cover half exhaust block top has exhaust hole, and described moving die exhaust block bottom has charging aperture, and described exhaust hole and charging aperture are connected two ends, exhaust passage respectively; Described exhaust projection is divided into length exhaust projection and short exhaust projection, and described short exhaust projection is arranged on charging aperture side, and the length that the described short length being vented projection is vented projection than length is little by 10% ~ 40%.
Preferably, described long exhaust projection is 8, and described short exhaust projection is 2.Preferably, the little 2cm of length that the length that short exhaust is protruding is more protruding than long exhaust.Because exhaust indent matches with the profile of exhaust projection, therefore do not repeat.
Preferably, described charging aperture is Y type charging aperture, enters exhaust block inside for aluminium alloy.
Exhaust hole is used for gas to discharge outside, and preferably, described exhaust hole is screwed hole, is connected with pumped vacuum systems.
Preferably, described exhaust is protruding is trapezium structure with the horizontal section of exhaust indent.Exhaust passage is zigzag structure.Exhaust is protruding and be vented the contact surface that indent is uniformly distributed in cover half exhaust block and moving die exhaust block.
Preferably, described cover half exhaust block and moving die exhaust block inside are equipped with fortune water pipe, for the cooling of exhaust block.Described fortune water pipe comprises inlet opening, apopore and U-shaped passage.Described U-shaped passage is made up of three straight channel, the first, the 3rd straight channel forms inlet opening and apopore on exhaust block surface, second straight channel has a fabrication hole at exhaust block side surface, and this fabrication hole utilizes normal drill bit to be drilled to, and the other end then leaves surplus and do not bore.Described fabrication hole adopts Technology of Welding to seal up.Preferably, described paddle hole is screwed hole.
Preferably, the both sides of described cover half exhaust block and moving die exhaust block are equipped with positioning boss, for cover half exhaust block being connected with moving die exhaust block and being fixed on mould.In addition, the back side of cover half exhaust block and moving die exhaust block all also has four screwed holes.Positioning boss should avoid the position of fabrication hole.
Compared with prior art, the beneficial effects of the utility model are as follows: be vented structural design that is protruding and corresponding short exhaust indent by short, except meeting except the scavenging action of mould, also because increase the envelope charge level of exhaust block body near charging aperture, exhaust block is enable to bear the type power that rises powerful when aluminium alloy has just entered exhaust block, avoid exhaust block to produce and fly material, thus effectively ensure that the safe handling of exhaust block and the molding effect of foundry goods.

Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.
See Fig. 1 ~ 5, novel anti-the flying of a kind of die casting expects exhaust block, be made up of embedding cover half exhaust block 1 and moving die exhaust block 2, the one side that cover half exhaust block 1 is relative with moving die exhaust block 2 is respectively arranged with the exhaust indent 4 being vented projection 3 and matching with protruding 3 profiles of exhaust, forms exhaust passage 5 between exhaust protruding 3 and exhaust indent 4; Cover half exhaust block 1 top has exhaust hole 6, and moving die exhaust block 2 bottom has charging aperture 7, and exhaust hole 6 and charging aperture 7 are connected two ends, exhaust passage 5 respectively; Exhaust protruding 3 is divided into long exhaust protruding 31 and short exhaust protruding 32, and short exhaust protruding 32 is arranged on charging aperture 7 side, and the length of short exhaust projection 32 is less by 10% ~ 40% than the length of long exhaust protruding 31.
Long exhaust protruding 31 is eight, and short exhaust protruding 32 is two.Because exhaust indent 4 matches with the profile of exhaust protruding 3, therefore do not repeat.
Charging aperture 7 is Y type charging aperture, enters exhaust block inside for aluminium alloy.
Exhaust hole 6 is outside for gas is discharged, and exhaust hole 6 is preferably screwed hole, is connected with pumped vacuum systems.
Exhaust protruding 3 is trapezium structure with the horizontal section of exhaust indent 4.Exhaust passage 5 is zigzag structure.Exhaust protruding 3 is uniformly distributed in the contact surface of cover half exhaust block 1 and moving die exhaust block 2 with exhaust indent 4.
Cover half exhaust block 1 and moving die exhaust block 2 inside are equipped with fortune water pipe 8, for the cooling of exhaust block.Fortune water pipe 8 comprises inlet opening 81, apopore 82 and U-shaped passage 83.Described U-shaped passage is made up of three straight channel, the first, the 3rd straight channel forms inlet opening 81 and apopore 82 on exhaust block surface, second straight channel has a fabrication hole 84 at exhaust block side surface, and this fabrication hole 84 utilizes normal drill bit to be drilled to, and the other end then leaves surplus and do not bore.Described fabrication hole 84 adopts Technology of Welding to seal up.Preferably, described paddle hole 81,82 is screwed hole.
The both sides of cover half exhaust block 1 and moving die exhaust block 2 are equipped with positioning boss 9, for cover half exhaust block 1 being connected with moving die exhaust block 2 and being fixed on mould.In addition, the back side of cover half exhaust block 1 and moving die exhaust block 2 all also has four screwed holes 10.Positioning boss 9 should avoid the position of fabrication hole 84.
Compared with prior art, the beneficial effects of the utility model are as follows: be vented structural design that is protruding and corresponding short exhaust indent by short, except meeting except the scavenging action of mould, also because increase the envelope charge level of exhaust block body near charging aperture, exhaust block is enable to bear the type power that rises powerful when aluminium alloy has just entered exhaust block, avoid exhaust block to produce and fly material, thus effectively ensure that the safe handling of exhaust block and the molding effect of foundry goods.
Only as described above, be only the preferred embodiment of the utility model, when can not limit the scope of the utility model enforcement with this, namely generally according to equivalence change simple done by the content described in the utility model claim and utility model description and modification, all still belong within the utility model claim scope.In addition, summary part and title are only used to the use of auxiliary patent document search, are not used for the interest field of restriction the utility model.
