Abstract
The invention discloses a casting technology of an engine cylinder cap. In casting, a guide pipe hole of an assembly sand core for molding the engine cylinder cap is internally provided with a cooling sleeve; the outer wall of the cooling sleeve is fit with the inner wall of the guide pipe hole; the cooling sleeve and liquid iron are condensed together to form a blank. By the casting technology of the engine cylinder cap, the hole contraction rate of the guide pipe hole is reduced, and the hole contraction waste product of the cylinder cap casting is reduced.
Description
Technical field
The present invention relates to the casting field of engine, particularly a kind of casting technique of engine cylinder cover.
Background technology
At present, in the casting technique of engine cylinder cover, such as S2000 cylinder cap, the guide hole of cylinder head is by coming in cylinder head casting (entity corresponding on cylinder head casting) upper machined, guide hole does not allow to there is gas leakage situation, so the casting of entity part corresponding on cylinder head casting is very crucial, otherwise directly affects overall engine performance.And the wall thickness at guide hole place is the thickest, very easily produces shrinkage cavity, to the level making the guide hole contraction cavity ratio of S2000 cylinder cap remain on 50% always.
The information being disclosed in this background technology part is only intended to increase the understanding to general background of the present invention, and should not be regarded as admitting or imply in any form that this information structure has been prior art that persons skilled in the art are known.
Summary of the invention
The object of the present invention is to provide a kind of casting technique of engine cylinder cover, reduce the contraction cavity ratio of guide hole, reduce the shrinkage cavity waste product of cylinder head casting.
For achieving the above object, the invention provides a kind of casting technique of engine cylinder cover, during cast, in the guide hole of the assembling core of shaping engine cylinder cover, place coolant jacket, the inwall of the outer wall laminating guide hole of this coolant jacket, coolant jacket solidifies formation blank together with molten iron.
Preferably, crossing with the guide hole of assembling core have oil-through hole, and the position that the outer wall of coolant jacket is aimed at oil-through hole is provided with resigning hole.
Preferably, coolant jacket comprises cylindrical shell and bridging, in the guide hole that cylindrical shell is fixed on assembling core by putting up a bridge.
Preferably, the mistake nail position extended near guide hole of putting up a bridge, the termination hook joint of bridging is at the edge crossing nail.
Preferably, the copper coating process of coolant jacket.
Compared with prior art, the present invention has following beneficial effect: by placing coolant jacket in the guide hole of the assembling core of shaping engine cylinder cover, in guide hole, the cylindrical shell of coolant jacket and molten iron reach the effect of chilling and cooled and solidified simultaneously, fully fused and fastening effect by cylindrical shell and molten iron, reduce the contraction cavity ratio of guide hole, reduce the shrinkage cavity waste product of cylinder head casting.

Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention not by the restriction of detailed description of the invention.
Clearly represent unless otherwise other, otherwise in whole description and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or part, and do not get rid of other element or other part.
As shown in Figure 1, according to the casting technique of a kind of engine cylinder cover of the specific embodiment of the invention, during cast, coolant jacket 1 (see Fig. 2) is placed in the guide hole of the assembling core 2 of shaping engine cylinder cover, the inwall of the outer wall laminating guide hole of this coolant jacket 1, coolant jacket 1 solidifies formation blank together with molten iron.In the present embodiment, coolant jacket 1 comprises cylindrical shell 12 and puts up a bridge 11, cylindrical shell 12 is fixed in the guide hole of assembling core 2 by bridging 11, particularly, bridging 11 extends to the mistake nail position near guide hole, the termination hook joint of bridging 11 is at the edge (termination see the bridging 11 of Fig. 2 is hook shape) crossing nail, in the present embodiment, for four cylinder cylinder caps, the combination core casting this cylinder cap has 4 guide holes respectively, place a coolant jacket 1 in each guide hole, and be fixed on assembling core 2 by identical mode.
As a kind of preferred embodiment, crossing with the guide hole of assembling core 2 have oil-through hole, the position that the outer wall of coolant jacket 1 is aimed at oil-through hole is provided with resigning hole 13 (see Fig. 2), the object arranging resigning hole 13 is, the larger fur quality of hardness can not be formed in the intersection of guide hole and oil-through hole, easily hole when following process oil-through hole, can borehole perpendicularity be ensured.
In such scheme, plane steel plate is as shown in Figure 4 rolled into the coolant jacket 1 shown in Fig. 2, and bridging 11 has certain width (see Fig. 3).In addition, the copper coating process of coolant jacket 1, the surface clean of coolant jacket 1, without greasy dirt with without rust staining, coolant jacket 1 has not allowed pit, interlayer phenomenon, has not allowed evagination burr burr, and cylindrical shell 12 is vertical with bridging 11.
In sum, the casting technique of the engine cylinder cover of the present embodiment by placing coolant jacket 1 in the guide hole of the assembling core 2 of shaping engine cylinder cover, in guide hole, cylindrical shell 12 and the molten iron of coolant jacket 1 reaches the effect of chilling and cooled and solidified simultaneously, fully fused and fastening effect by cylindrical shell 12 and molten iron, reduce the contraction cavity ratio of guide hole, reduce the shrinkage cavity waste product of cylinder head casting.This technique is a kind of comprehensive casting technique obtaining effectively checking of novelty, this technique and through many experiments to test manufacture, its effect is better, without quality problems, and easy and simple to handle, compared with original production technology increase by put the link of coolant jacket, but control to play a significant role to the contraction cavity ratio of the guide hole of cylinder cap, shrinkage cavity percent defective drops to 16.63% by original 54%.And any change is not carried out to original production equipment, moulds of industrial equipment structure, and easy to operate, on original technological process of production without any impact.
The aforementioned description to concrete exemplary of the present invention is to illustrate and the object of illustration.These descriptions not want the present invention to be defined as disclosed precise forms, and obviously, according to above-mentioned instruction, can much change and change.The object selected exemplary embodiment and describe is to explain certain principles of the present invention and practical application thereof, thus those skilled in the art can be realized and utilize various different exemplary of the present invention and various different selection and change.Scope of the present invention is intended to limited by claims and equivalents thereof.
