Abstract
A kind of use exhaust apparatus of bleeding for the exhaust of aluminium alloy casting mould core, comprise be loaded on mould pump-line on body for being vented for core, stepped hole is had in the middle part of body, the small stair hole that described stepped hole comprises the large stepped hole corresponding with core, is connected with large stepped hole, large stepped hole is built with the filler for filtering flue gas, and small stair hole is built with venting plug; The body end contacted with core is provided with the dope layer for preventing aluminium liquid and filler from sticking together.At present, for the aluminium alloy casting mould having core, for the ease of core exhaust, all venting plug can be set at core print place, but the venting plug manufacture difficulty of existing core exhaust is comparatively large, exhaust effect is bad and not easy to clean, need mould be dismantled when changing, affect production efficiency.The utility model structure is simple, easy to use, durability is high, can realize the fast-assembling quick change under continuous seepage situation.
Description
Technical field
The utility model relates to casting technique apparatus field, especially relates to a kind of bleeding and use exhaust apparatus for the exhaust of aluminium alloy casting mould core.
Background technology
At present, for the aluminium alloy casting mould having core, for the ease of core exhaust, all venting plug can be set at core print place.According to the feature that core is got angry, generally all exhaust core print can be arranged upwards.When as required, exhaust core print must downwards time, just need to utilize air extractor to carry out forced-ventilated, enter foundry goods to prevent core by thermogenetic gas and cause foundry goods to produce gas the defect and scrapping such as to choke.Venting plug for core exhaust is generally trickle netted or clearance type structure, and material is steel or copper.Its weak point is: one is limit by structure, adopt material to be rigid material, use required pore-size little again, manufacture difficulty is comparatively large, needs specialized factory to make; Two is in use procedure, due to core the materials such as the resinous flue gas waiting bonding agent pyrolytic to produce easily cause micropore to block, affect exhaust effect and not easy to clean; Three is that crash rate is high, within during continuous seepage three to four days, needs to change, and need dismantle mould, affect production efficiency during replacing.
Summary of the invention
Goal of the invention of the present utility model provides that a kind of structure is simple, easy to use, durability is high to overcome prior art above shortcomings, and what can realize the fast-assembling quick change under continuous seepage situation uses venting plug for bleeding of aluminium alloy casting mould core exhaust.
The technical solution of the utility model is: comprise be loaded on mould pump-line on body for being vented for core, stepped hole is had in the middle part of body, the small stair hole that described stepped hole comprises the large stepped hole corresponding with core, is connected with large stepped hole, large stepped hole is built with the filler for filtering flue gas, and small stair hole is built with venting plug; The body end contacted with core is provided with the dope layer for preventing aluminium liquid and filler from sticking together.
Described dope layer is arranged at body upper surface.
Described filler is sponge or asbestos.
Described body is cylindrical-shaped structure, and periphery is provided with external screw thread.
Described body upper surface is provided with the yi word pattern groove for coordinating a cutter adjusting device and dies cavity relative position.Described stepped hole is step cylindrical hole.
When using the utility model operation, dope layer effectively avoids cavernous body filler and core adhesion, and core is drawn out of outside die cavity by base bleed plug by bleed-off passage, to reach exhaust object by thermogenetic flue gas after cavernous body filler filters.Base bleed plug can prevent cavernous body filler from falling into pump-line and producing blocking simultaneously.Produce exhaust gas volumn size according to core, by checking, determine the cavernous body filler replacement cycle, change in time and can continue after sprayed coating to produce.When the utility model produces damage, owing to adopting screw thread quick change construction, also can change in time, thus ensure that production can be carried out continuously.
The utility model has the advantages that: the design of housing central section stepped hole meets safety when loading filler: because generally can compress when filler filling, if be arranged to through hole, all venting plug can be had influence on when each compression filler, if the words that venting plug fills not tight, venting plug may be pushed away, filler will fall into bleed-off passage.Be designed to the stepped hole of small stair bottom the large step in top, the probability pushing away venting plug during compression can reduce greatly, even and if venting plug fallen, filler because there is stop, is also unlikely to fall into bleed-off passage and cause channel blockage.
The utility model structure is simple, easy to use, durability is high, can realize the fast-assembling quick change under continuous seepage situation.Adopt replaceable cavernous body filler and ensure change at any time and do not affect exhaust effect and productivity ratio.

Detailed description of the invention
In Fig. 1, in Fig. 2, the utility model comprises body 1, cavernous body filler 2, yi word pattern groove 3, dope layer 4, venting plug 5.Be helicitic texture outside body 1, inside arranges stepped hole, and in-line groove is arranged at top, and stepped hole is circular hole.Cavernous body filler 2 is filled in body 1 stepped hole top.Dope layer 4 is covered in cavernous body filler 2 outer surface.Venting plug 5 is embedded in bottom stepped hole.
In Fig. 3, the utility model utilizes helicitic texture to be connected with mould 8 before using, and screwdriver can be used to pass through body 1 top in-line groove 3 and regulate and mould 8 inner chamber relative position, complete the utility model to install, installation site does not affect again core 6 and to coordinate with mould 8 to touch core 6 and be advisable.After core 6 is steadily placed to mould 8, casting complete starts air extractor 9 simultaneously.Now because core 6 is all wrapped up by foundry goods 7 except core print, high temperature causes the agent of core 6 internal bond decompose and produce flue gas, due to the forced-ventilated effect of air extractor 9, the flue gas produced enters exhaust passage by dope layer 4, cavernous body filler 2 and venting plug 5, is finally discharged outside mould 8.
When using the utility model, the flue gas produced due to most core is filtered out by cavernous body filler 2, greatly can extend the service life of venting plug 5.Only need during conventional maintenance to change cavernous body filler 2 in time as required.If venting plug 5 blocks, only the utility model need be taken out, cleaning or replacing venting plug 5.
