Description
Technical field
Patent of the present invention relates to a kind of method of water hole tenon technological design on cylinder head lower water jacket core, at engine air
It is applied during the tenon casting Technology Design of water hole on cylinder cap lower water jacket core.
Background technology
On traditional cylinder head lower water jacket, water hole tenon shape is to be designed to round core head, at Fig. 1 height with upper water hole shape
Direction the second gap location is placed with gap, causes upper water sleeve core to become under gravity after upper water sleeve core and chassis core core assembly
Shape, at position 2, the gap in the second gap diminishes, so that whole jacket core local sand lump moves down, upper water sleeve core and chassis core shape
The wall thickness become will be thinning, and the local wall thickness ultimately resulting in foundry goods is uneven.As certain cylinder head lower water jacket core coordinates with chassis core
Technological design theory wall thickness be 6mm, but dissect foundry goods find lower water jacket local wall thickness only have 4.5mm, this example is from other one
Individual side reflects core and deforms the final consequence caused, and the most how preventing lower water jacket core to deform after core assembly is casting
The process difficulties that Designer Craftman is urgently to be resolved hurrily.
Summary of the invention
Present invention aim to address the problem that cylinder head lower water jacket core is deformed after core assembly, additionally this patent also has
Minimizing casts the advantages such as the assembling positioning precision of burr, core assembly mistake proofing, raising core.
The technical solution of the present invention is such that water hole core tenon on a kind of cylinder head lower water jacket, including first
Gap, the second gap, third space, lower water jacket core, chassis core, oblique distance, blind mortise head hole, tenon head, not conformal tenon, it is special
Levying and be lower water jacket core (4) at chassis core (5) above, the tenon head (8) of lower water jacket core (4) inserts the recessed of chassis core (5)
Tenon hole (7), tenon head (8) be not conformal tenon (9), not conformal tenon (9) and blind mortise head in blind mortise head hole (7) contact portion
The shrinkage pool in hole (7) coordinates to be manufactured, when not conformal tenon (9) of tenon head (8) loads blind mortise head hole (7), and itself and the gap of hole wall
Be the first gap (1) be 0mm, the second gap (2) are 0～5mm, and third space (3) is 0.1～1.0mm, oblique distance (6) be 5～
30mm, the gradient of conformal tenon (9) external diameter is not 3～15 degree, not the length of conformal tenon (9) be tenon head (8) 1/2 with
On, tenon head (8) and not conformal tenon (9) they are circular, and blind mortise head hole (7) is circular.
Tenon head (8), not conformal tenon (9) have more than one at lower water jacket core (4).
Blind mortise head hole (7) has more than one at chassis core (5).
Conformal tenon (9) is not cone circle.
Blind mortise head hole (7) is cone circle.
Tenon head (8), blind mortise head hole (7) are consubstantiality.
Tenon head (8) is cylindrical.
Lower water jacket core (4) loads onto chassis core (5) above, the tenon head (8) of lower water jacket core (4), not conformal tenon (9)
It is enclosed in blind mortise head hole (7) inner, is formed and have the first gap (1) between tenon head (8) bottom surface and the cavity floor of chassis core (5),
Third space (3), not conformal tenon (9) bottom face and blind mortise is not had between conformal tenon (9) external diameter and (7) limit, blind mortise head hole wall
There is the second gap (2) in head hole between (7) bottom surface.
Compared with prior art, the prominent effect of the present invention is: tenon head is designed as 2/3 or 1/2 circle of water hole shape
Shape, does not deforms spacing to core after core assembly, thus reaches to prevent the generation of core deformation, and the assembling improving core further is fixed
Position precision.Due to 2/3 or 1/2 circle of tenon head upper water hole shape, the casting burr therefore formed is whole more round-formed than one
Casting burr few.If the tenon of conformal direction during core assembly, not to not organizing core, does not therefore have core assembly and prevents
Wrong function.
Accompanying drawing explanation
Fig. 1 is that the single tenon of the present invention coordinates schematic diagram.
Fig. 2 is that double the tenons of the present invention coordinate schematic diagram.
Reference: the first gap (1), the second gap (2), third space (3), lower water jacket core (4), chassis core (5),
Oblique distance (6), blind mortise head hole (7), tenon head (8), not conformal tenon (9).
