Description
Technical field
This utility model is related to electromotor sand casting field, particularly to a kind of staged core mold.
Background technology
Large diesel engine at present, the particularly manufacture of big marine diesel engine, is all full sand casting.Its core, due to
Its overall dimensions is big, complex structure it is impossible to enter production on line by die apparatus, and majority be by design some aluminum dipping forms,
The craft core box such as wooden model, the modern designs of plastics carrys out artificial coremaking.
Manufacture the manual core box used by core, usually spliced, be fixed together by multiple loose pieces and form.Manual
The coremaking process of core box, typically from workman toward core box die cavity in fill up self-hardening sand, strike off core box face；Treat the self-hardening sand in core box
After solidification, loose piece is taken apart, take out core.
During manual core box coremaking, there is a key link it is simply that striking off core surface.Existing manual core box
Coremaking process, be all to fill up self-hardening sand in core box, self-hardening sand solidify before, workman will exceed core box part using scraper plate
Self-hardening sand, the upper surface along core box strikes off, and the surface striking off is the final outer surface of core.
After core solidification, workman needs to overturn core box, and loose piece is taken apart in order, after taking-up core, then by core
Box loose piece assembly is got up, back-up sand again, and the core carrying out a new round makes.
Existing manual core box requires although the general making of core used by large diesel engine casting can be met.But it is this
The mould structure of manual core box and core-making method still suffer from certain defect and limitation, are mainly manifested in：
1st, the inlaid type core box that mould core box is made up of multiple loose pieces, loose piece needs to dismount during coremaking,
Complex operation.
2nd, the sand exceeding core box needs to strike off, and this brings limitation just to the coremaking of manual core box：Outside the core making
The plane that surface must be, otherwise cannot be carried out strike-ofing.For some complicated staged cores, then cannot be by manual core box
Once complete the making of whole core；And be intended to a core and be divided into two cores or multiple along cascaded surface, make respectively, then will
Two or more cores are stitched together and form desired core.Splicing core, impact group core efficiency.
3rd, location of the coring procedure, needs workman to overturn core box, loose piece could be taken apart in sequence.With core
Core box, overall dimensions are big, and weight is heavier, and the upset of core box needs to expend a large amount of human and material resources.
From above-mentioned some can be seen that existing manual core box, not only increase the labor intensity of workman, and serious shadow
Sound has arrived core making, the efficiency of assembling it is impossible to meet large diesel engine, and the batch production of particularly big marine diesel engine needs
Ask.
The information being disclosed in this background section is merely intended to increase the understanding to general background of the present utility model, and
It is not construed as recognizing or imply in any form that this information structure has been existing well known to persons skilled in the art
Technology.

The both sides of the core projection side plate 14 of housing 1, and strained by tie down screw 7, form the shape of core bossing.For rank
Part smooth for core lower end, after completing sand, is first struck off by the bossing of ladder type core；Cross core lobe with baffle plate again
Divide shape, carry out secondary sand filling, strike off, complete final coremaking process so that back-up sand twice completes the integral manufacturing of core.Sand
Core does not need sectional making, and not only sand core strength is improved, and solve the Bonding Problem of core, it is to avoid sand during group core
The complicated processes of core splicing, effectively raise group core efficiency.
As shown in fig. 6, ejecting mechanism 5 includes：Plunger tip plate 51 and plunger tip bar 52, plunger tip plate 51 is rectangular plate-like, plunger tip bar
52 are many, are inserted in the corresponding plunger tip rod aperture 21 of core box body 2, during assembling, plunger tip plate 51 is laid in core box body 2
The base plate 11 of metal outer frame 1 below, many plunger tip bars 52 respectively with plunger tip rod aperture 21 (these on corresponding core box body 2
Hole is corresponding with the plunger tip rod aperture 13 on metal outer frame 1 base plate 11) it is aligned, it is inserted from above into.The base plate of metal outer frame 1 and ejector
It is provided with distance block 6 (setting ejection stroke) between the plunger tip plate 51 of structure 5.The plunger tip bar of ejecting mechanism 5 inserts core box body 2
Each plunger tip rod aperture can complete the ejection process of core so that location of the coring procedure does not need to overturn core box using the deadweight of core box.This
A little labor intensity not only mitigating workman, and greatly improve the make efficiency of core.
Specific core-making method：
1st, a back-up sand, makes core body part；
As shown in fig. 7, when making core, the incipient stage, elder generation was in the die cavity of core box body 2 it is not necessary to load onto two pieces of baffle plates
Part is filled up self-hardening sand 8 and is formed core box body part, and strikes off；
2nd, secondary sand filling, makes core bossing；
As shown in figure 8, after striking off the core of core box body part, loading onto two pieces of baffle plates, fixing, then toward between two baffle plates
Continue in die cavity to fill up self-hardening sand 8, strike off, complete the making of whole core.Treat that core solidifies, take baffle plate apart, carry out plunger tip behaviour
Make.
3rd, eject core；
As shown in Figure 9 and Figure 10, after core completes, take baffle plate apart, take out sprue apperance；Workman will carry core 9
Metal outer frame 1 and core box body 2 lever up, remove distance block, the deadweight using metal outer frame 1 and core box body 2 completes core
Ejection process.After taking core 9 away, lift the core box of sky, put back to distance block, carry out the core manufacturing process of a new round.
To sum up, this staged core mold can either avoid the complicated processes such as the upset of manual core box, dismounting；Again can be real
The integral manufacturing of existing complicated staged core, saves being fabricated separately of core, splicing.The strong of core can not only be increased
Degree, mitigates the labor intensity of workman, and effectively raises coremaking, the efficiency of group core, greatly meets present argosy
Demand with diesel engine batch production.
The aforementioned description to specific illustrative embodiment of the present utility model illustrate that and illustration purpose.These
Description is not wishing to for this utility model to be defined to disclosed precise forms, and it will be apparent that according to above-mentioned teaching, can carry out
A lot of changes and change.The purpose of selecting and describing the exemplary embodiment is that explaining certain principles of the present utility model
