Referring to Fig. 6, Fig. 6 is a kind of flow chart for center module processing method that the embodiment of the present application one provides.It is described
Center module processing method is used to process the center component 10 that any embodiment as above provides.The center module processing method packet
Step S100, S200 and S300 are included but are not limited to, about being described in detail as follows for step S100, S200 and S300.
S100：Blank is provided, die casting is carried out to the blank, with plate ontology 210 in being formed and from the middle plate ontology 210
The first extension 220 and the second extension 230 that side extends out.
Wherein, die casting is a kind of metal casting technique, its main feature is that applying high pressure to molten metal using mold inner-cavity.
Mold is usually to be made of higher strength alloys, this process some similar to injection molding.According to die casting type
Difference is needed using cold-chamber die casting machine or hot chamber machine.
Wherein, first extension 220 and second extension 230 are located at the side of the middle plate ontology 210.
Referring to Fig. 7, Fig. 7 is a kind of corresponding local flow chart of step S100 of the embodiment of the present application.Specifically, described
"S100：Blank is provided, die casting is carried out to the blank, is prolonged with plate ontology 210 in formation and from middle 210 side of plate ontology
The first extension 220 and the second extension 230 " stretched include but is not limited to step S110, S120, S130 and S140, are closed
In being described in detail as follows for step S110, S120, S130 and S140.
S110：The blank is melted at high temperature, to obtain the melting charge of liquid.
Specifically, the blank is placed in high temperature-resistant vessel, then high temperature-resistant vessel is heated, works as high temperature resistant
When the temperature of vessel reaches the fusing point of the blank, the blank will be melted, and then can be obtained by the melting of liquid
Material.
S120：Casting mould is provided.
Wherein, casting mould refers to obtain the planform of part, is easy molding material with other in advance and is made into
Then the planform of part is put into mold in sand mold again, one and design of part size one are then formed in sand mold
The cavity of sample, then it is poured mobility liquid in the cavity, it can be formed after the liquid cooled and solidified and mold shape structure
Duplicate part.
S130：The melting charge of liquid is poured into the type chamber of the casting mould by the feed inlet of the casting mould
It is interior.
Specifically, casting mould is the melting charge high speed press-in die type chamber by Driven by Hydraulic Cylinder injection plunger by liquid
In, due to being to use oil pressure, pressure is higher, therefore is commonly called as casting mould technique.
Referring to Fig. 8, Fig. 8 is corresponding local flow chart after a kind of step S120 of the embodiment of the present application.Optionally, exist
" the S120：Casting mould is provided " after, in " the S130：The melting charge of liquid is passed through into the charging of the casting mould
The type that mouth is poured into the casting mould is intracavitary " before, the center module processing method further includes but is not limited to step S122,
About being described in detail as follows for step S122.
S122：The type chamber of the casting mould is cleaned, and coats lubricant on the inner wall of the type chamber, it is described
Lubricant is for preventing the casting mould temperature excessively high, and the lubricant is also used to so that the middle plate ontology 210 and institute
Extension is stated to demould from the casting mould.
Wherein, most common lubricant type is water base lubricant, also referred to as emulsifier, this is for health, environment
And the considerations of in terms of safety.Unlike solvent type lubricant, if the minerals in water got rid of with suitable technique,
It will not leave by-product in casting.If the process for handling water is not proper, the minerals in water will lead to casting table
Planar defect and discontinuity.There are mainly four types of water base lubricants：Water mixes oil, oily water mixing, semi-synthetic and synthesis.What water was mixed oil
Lubricant is best, because can be by the surface of the cooling mold of evaporation while depositing oil using water when lubricant, this can
To help to demould.In general, the water that the ratio of this series lubricant agent is 30 parts mixes 1 part of oil.And in extreme circumstances, this ratio
It can achieve 100：1.
Optionally, the oil that can be used for lubricant includes heavy oil, animal tallow, plant fat and Synthetic Oil.Heavy
Viscosity is higher at room temperature for Residual oil, and at a high temperature of in die-casting process, it will become film.Other materials are added in lubricant
It can control emulsion viscosity and thermal property.These substances include graphite, aluminium and mica.Other chemical addition agents can be kept away
Exempt from dust and oxidation.Emulsifier can be added in water base lubricant, such oil lubricant can add in water inlet, including
Soap, alcohol and ethylene oxide.
Optionally, the lubricant based on usually used solvent includes diesel oil and gasoline.It is de- that they are conducive to casting
Out, however small blasting can occur in press casting procedure every time, this causes to build up carbon in die cavity wall.Compared to water based lubrication
Agent, the lubricant based on solvent are more uniform.
Referring to Fig. 9, Fig. 9 is a kind of corresponding local flow chart of step S130 of the embodiment of the present application.Optionally, described
"S130：Type that the melting charge of liquid is poured into the casting mould by the feed inlet of the casting mould is intracavitary " include but
It is not limited to step S135, is described in detail as follows about step S135.
S135：The pressure that pressure is greater than default pressure is applied to the melting charge of liquid, the melting charge is injected
Type to the casting mould is intracavitary, until the melting charge of liquid solidifies.
Wherein, pressure limit is about between 10 to 175 megapascal.
Specifically, high-pressure injection melting charge causes the speed for filling casting mould very fast, in this way any portion of molten
Before melting material solidification, so that it may fill full entire casting mould.In this way, the thin-walled portion for being just difficult filling at last can also
To avoid the discontinuity on casting mould surface.
