Abstract
The utility model relates to an automobile engine intake manifold with a thin-wall throttle flange, which solves the problems that the throttle flange part of an existing automobile engine intake manifold is designed to be quite thick, the internal tissue of the throttle flange part in a production process is easy to be loosened and even shrink, so that the casting in a throttle flange installation hole is defective, the airtight pass rate of a casting is seriously affected and the production cost is high, and is characterized in that a sideline around the throttle flange is a connected curve which is concave around; the throttle flange is sealed and is in a circular shape; a throttle flange seal strip and a throttle installation platform form the thin-wall throttle flange which is concave around; and the automobile engine intake manifold with the thin-wall throttle flange has the beneficial effects that casting defects in the throttle flange installation hole of the intake manifold are prevented, compact tissue is realized, overall mechanical properties of the product are improved, the part pass rate is improved, and because the thin-wall throttle flange structure is adopted, raw materials are saved and the production cost is reduced.
Description
Technical field
The utility model belongs to technical field of automobile engine, particularly a kind of thin-walled closure flange air intake manifold of automotive engine.
Background technique
Air intake manifold of automotive engine is the critical component of automotive engine air intake system, in the prior art, it is thicker that air intake manifold of automotive engine closure flange position is designed, be that the sideline is straight line around the closure flange, form a rectangular flange, the relative broad of its closure flange seal band, the thickness of this flange from flange closure aperture to rectangular flange outer rim sideline is thicker, bigger with the thickness difference at other positions of air intake manifold of automotive engine, be difficult to guarantee the foundry goods consecutive solidification in the production process, especially closure flange position interior tissue easily produces loose even shrinkage cavity, cause casting defect in the closure mounting hole, have a strong impact on the airtight up-to-standard rate of foundry goods, cost of production is increased.
Summary of the invention
Technical problem to be solved in the utility model is, overcomes the deficiencies in the prior art part, and a kind of a kind of thin-walled closure flange air intake manifold of automotive engine that guarantees no casting defect in the intake manifold closure mounting hole is provided.
Technical solution adopted in the utility model comprises resonant cavity and first suction tude that is connected with resonant cavity, second suction tude, the 3rd suction tude, the 4th suction tude and cylinder cap mounting flange, on resonant cavity, be cast with the closure flange, closure flange sideline is a continuous curve of indent all around around the described closure flange, and closure flange seal band is rounded.
Compared with prior art, the benefit that the change of intake manifold throttle valve structure brings is, can guarantee no casting defect in the intake manifold closure mounting hole, thereby obtain fine and close tissue, improved the mechanical property of product integral body, also improved the part up-to-standard rate, owing to adopt thin-walled closure flange arrangement, also save raw material, reduced cost of production.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, the utility model comprises resonant cavity 6 and first suction tude 1 that is connected with resonant cavity 6, second suction tude 2, the 3rd suction tude 3, the 4th suction tude 4 and cylinder cap mounting flange 5, the suction tude 1 of four bendings, 2,3 and 4 upper ends are communicated with the bottom of resonant cavity 6, after with the side direction bending, end at cylinder head mounting flange 5, be cast with closure flange 7 on the resonant cavity 6, on first suction tude 1 and the 4th suction tude 4, be cast with an oily rail support boss 8 respectively, corresponding to first suction tude 1, second suction tude 2, the 3rd suction tude 3 and the 4th suction tude 4 each suction tude are cast with EFI hole 9 at cylinder head mounting flange 5 ends;
As shown in Figure 4, sideline 10-1 is straight line around the prior art closure flange, form a rectangular flange, the relative broad of its closure flange seal band 10-2, make that the thickness of closure flange from flange closure aperture 10-3 to rectangular flange outer rim sideline 10-1 is thicker, bigger with the thickness difference at other positions of air intake manifold of automotive engine; As shown in Figure 3, under the prerequisite of the minimum sealed width that guarantees closure flange seal band 7-2, closure flange sideline 7-1 is a continuous curve of indent all around around the utility model closure flange 7,7-2 is rounded for closure flange seal band, the thin-walled closure flange of closure flange seal band 7-2 indent around closure mounting platform 7-4 forms, make the closure flange from the aperture of closure flange solar term aperture of door 7-3 to around the obvious attenuate of wall thickness of closure flange sideline 7-1 of indent, less with the thickness difference at other positions of air intake manifold of automotive engine, reach unanimity, help guaranteeing consecutive solidification in the casting solidification process, obtain the closure mounting platform of dense structure, and then guarantee the mechanical property of intake manifold.
