Description
Technical field
The utility model relates to casting technology field, in particular to the shell mould parting casting device of a kind of small pump housing.
Background technique
The small pump housing is gear pump case component part, and transmission gear is installed in inner cavity, because its shape convex platform, concave surface are more
And inner cavity cannot achieve a parting and take all holes, chamber out of with the presence of multiple curved surfaces and asymmetric face, so cannot select to fit
In the device for sand coated iron mould technique of horizontal parting, also have in the prior art using resin sand, water-glass sand casting technique, however uses tree
The defects of cast-internal tissue manufactured by rouge sand, water-glass sand casting technique is not fine and close enough, and there are shrinkage cavity and porosities, in addition,
Cast(ing) surface has burr generation, and appearance, the structure property requirement of casting is not achieved.
Therefore, based on the above issues, the utility model provides a kind of shell mould parting casting device of small pump housing.
Summary of the invention
The purpose of the utility model is to provide a kind of shell mould parting casting device of small pump housing, solution in the prior art can not
The problem of realizing a parting, appearance, the structure property requirement of small pump housing shell casting be not achieved.It is cast by using shell mould parting
Device is made, it can be achieved that a parting and not needing casting mould and swage sandbox, effectively save cost；Reach small pump housing shell
The appearance of casting, structure property requirement.
The utility model is achieved through the following technical solutions:
The shell mould parting casting device of the small pump housing, including small pump housing shell mo(u)ld bottom half core, small pump housing shell upper core, inner core,
Cast gate cup type core and shot；
Small pump housing shell mo(u)ld bottom half core includes lower core print and mould assembling boss flanging seam allowance, and lower core print is located at small pump housing shell mo(u)ld bottom half
The lower plane of the lower bottom part of core, small pump housing shell mo(u)ld bottom half core fills shot；
Small pump housing shell upper core connects small pump housing shell mo(u)ld bottom half core, and small pump housing shell upper core includes Double-ear-hole, inner core

It is designed in this way, firstly, by using shell mould parting casting device, by small pump housing shell mo(u)ld bottom half core, small pump housing shell
Upper core, inner core, cast gate cup type core combination once casts out small pump housing inner cavity of different shapes, effectively solve in the prior art due to
The problem of small pump housing shell casting complex contour cannot achieve depanning of horizontal parting, and do not need casting mould and swage sand
Case, effectively save cost；Then, the heat-conducting medium of shell casting uses shot, and shot heat conductivity is close to swage sandbox, institute
This body tissue of casting, metallographic performance are equal to device for sand coated iron mould casting out, and the shrinkage cavity and porosity in small pump housing shell casting structure lacks
Sunken generation is inhibited, and will not generate；Finally, shot landfill gravity makes the boss flanging fixing structure of small pump housing type core in addition
Small pump housing type core integrally fastens, and then it is very bright and clean to obtain small pump housing shell cast(ing) surface, the not generation of burr.
As optimization, shot uses diameter for the ball shot of 3-4mm.It is designed in this way, effect is more preferable.
The beneficial effects of the utility model are:
It is the utility model design science, easy to operation, by using shell mould parting casting device, by upper and lower shell body
Upper additional core print and small-sized core combination can once cast out its inner cavity of different shapes, do not need casting mould and swage sandbox, have
Imitate save the cost；In addition, the generation of the shrinkage cavity and porosity defect in small pump housing shell casting structure is inhibited, will not generate；This
Outer small pump housing shell cast(ing) surface is very bright and clean, the not generation of burr.It is the strong benefit to iron die sand casting process
It fills, rich in dissemination.

Specific embodiment
For the purpose of this utility model, technical solution and advantage is more clearly understood, develop simultaneously implementation referring to the drawings
The utility model is further described in example.
The property simple and easy to operate of shell moulded casting can be realized the unpacking molding of various ways, so multiple to pump housing class shape and structure
Sundries is particularly suitable.The present embodiment selects self-hardening sand shell moulded casting scheme, and shell mould core manufacturing craft is hot box process mode, overlay film
Fineness of sand is in 70-140 mesh.
As shown in figures 1 to 6, the shell mould parting casting device of the small pump housing, including small pump housing shell mo(u)ld bottom half core 1, small pump housing shell
Upper core 4, inner core 7, cast gate cup type core 10 and diameter are the ball shot of 3-4mm；
Small pump housing shell mo(u)ld bottom half core 1 includes lower core print 2 and mould assembling boss flanging seam allowance 3, and lower core print 2 is located at small pump housing shell
The lower plane of the lower bottom part of mo(u)ld bottom half core 1, small pump housing shell mo(u)ld bottom half core 1 fills shot；
Small pump housing shell upper core 4 connects small pump housing shell mo(u)ld bottom half core 1, small pump housing shell upper core 4 include Double-ear-hole 5,
Inner core core print and casting down gate 6, Double-ear-hole 5 and casting down gate 6 are located at the middle part of small pump housing shell upper core 4, and ears
Hole 5 is located at 6 lower section of casting down gate；
Inner core 7 is placed in small pump housing shell mo(u)ld bottom half core 1, and inner core 7 includes inlet nozzle round core head 8 and ears 9, inlet nozzle circle
Core print 8 is located at 7 top of inner core, and ears 9 are located at 7 bottom of inner core.
To 10 4 kinds of above-mentioned small pump housing shell mo(u)ld bottom half core 1, small pump housing shell upper core 4, inner core 7, cast gate cup type core type cores
It is combined, forms casting mold shell, embedment ball shot casting nodularization iron liquid can cast out small pump housing shell casting.
The specific installation steps of the shell mould parting casting device type core of the above-mentioned small pump housing are as follows:
1, inner core 7 is placed in the lower core print 2 of small pump housing shell mo(u)ld bottom half core 1；2, small pump housing shell upper core 4 along conjunction
Being covered on small pump housing shell mo(u)ld bottom half core 1 gently of case boss flanging seam allowance 3, while observing twisting inner core 7 enters its ears 9
Into the Double-ear-hole 5 of small pump housing shell upper core 4；3, cast gate cup type core 10 is bonded in the casting of small pump housing shell upper core 4
On down gate 6 in plane, this completes entire group core process, be put into rectangular sandbox later filled with shot it is to be cast,
It is suitable for reading that note is intended to cover sprue cup, prevents shot from entering type chamber.
The characteristics of above-mentioned specific embodiment and principle are as follows:
1, self-hardening sand shell moulded casting scheme is selected, shell mould core manufacturing craft is hot box process mode, and precoated sand granularity is in 70-
140 mesh, mold cavity surface is very fine and close, smooth after coremaking depanning, and gone out surface quality of continuous castings is high.
2, by using shell mould parting casting device, by small pump housing shell mo(u)ld bottom half core, small pump housing shell upper core, inner core,
The combination of cast gate cup type core can once cast out small pump housing inner cavity of different shapes, effectively solve in the prior art due to small pump housing shell
