Description
Technical field
The present invention relates to cylinder head technical field, be specially a kind of method for casting cylinder cover of multicylinder one-cover engine.
Background technology
Cylinder cover is the lid of engine and closes the parts of cylinder, including water jacket and porthole and cooling fin.Cylinder cover be by
Cast iron or aluminum alloy cast system, be the installation matrix of valve mechanism, is also the sealing lid of cylinder, good cylinder and top land composition combustion
Burn room.Many has used a camshaft support base and tappet guide hole seat and cylinder cover structure cast in block.Cylinder cover damages
Phenomenon mostly is the deformation of raising one's head and looking (making sealing be destroyed) of cylinder cap and cylinder holes sealing plane, Valve seat porous dehiscence stricture of vagina, spark plug
Screw thread is installed damage but etc..The cylinder cap particularly poured with aluminium alloy, because its material hardness is relatively low, intensity is the most relatively poor, compares
It is easily deformed and damages, therefore consumption relatively cast iron is made as many.The casting of cylinder head should be noted that a lot of problem, especially at multi-cylinder
The casting of cylinder head needs special casting method, in order to avoid causing casting error.
Summary of the invention
It is an object of the invention to provide a kind of method for casting cylinder cover of multicylinder one-cover engine, to solve above-mentioned background skill
The problem proposed in art.
For achieving the above object, the present invention provides following technical scheme: a kind of cylinder cover of multicylinder one-cover engine casting side
Method, this method for casting cylinder cover of multicylinder one-cover engine specifically comprises the following steps that
The making of S1: sand mold mould, the cylinder head cast as required is to make mould, and sand mold mould uses without base core mould
Tool；
S2: cylinder head uses aluminum alloy materials, the melting of aluminium alloy castable, carries out detecting pouring of block before pouring simultaneously,
Detection block is the cuboid that length, width and height are respectively 10CM, 2CM and 1CM, for mechanical property and the chemical pouring material
The detection of energy；
Pouring of S3: cylinder head, by pouring mouth and pour in sand mold mould the aluminium alloy of melting, uses the mode quickly filling type to enter
Circulation of qi promoting cylinder cap pours；
S4: mould is removed in cooling, the cylinder head pouring molding is carried out cooling process, when temperature is down to 100-150 degree Celsius
Carry out mould to process；
S5: the cylinder head after removing mould carries out in Equipment for Heating Processing heat treatment, improves the mechanical performance of cylinder head；
S6: cylinder head is carried out sand removal process when cylinder head temperature is down to room temperature；
S7: to casting exhaust hood lid carry out burr and pour the process of mouth, by burr and pour mouth excision, simultaneously to cutting
Mouth carries out grinding process；
S8: the plane of cylinder head is carried out milling flat process, the plane roughness of milling is less than 1.6, simultaneously to the gas after casting
Cylinder cap carries out hole machined, processes the hole of needs according to drawing, and the roughness of processing hole inwall is less than 1.6；
S9: detect the detection block in S2, can carry out large batch of casting and use when material meets the requirements；
The high-volume casting of S10: cylinder head, repeats S1-S8 and carries out the casting of cylinder head.
Using casting mould to pour mouth in described cylinder head casting process is 2, in order to can be quick in casting process
The pouring material that makes be full of in mould.
Need to carry out the detection of cylinder head after the high-volume casting of described cylinder head, it is impossible to use sampling Detection, need to carry out
All detections, substandard product needs to destroy.
Compared with prior art, the invention has the beneficial effects as follows: the present invention uses double teeming to build mouth and pours, in order to quickly
The aluminum alloy melt that makes quickly be full of in die cavity, the most first to carry out detecting the casting of block, in order to can be to casting simultaneously
Producing material material detects, in order to obtain the various performance datas of founding materials, in order to be preferably the casting service of cylinder head.
Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with specific embodiment, to this
Invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, not
For limiting the present invention.
