Abstract
The invention discloses a front hood of a minibus and relates to the technical field of casting of automotive spare parts. The front hood is characterized by comprising the following ingredients by weight percentage: 55-66% of Al2O3, 72-83% of molten steel, 12.5-22.5% of phenolic resin, 8-15% of ammonium bicarbonate, 4-10% of potassium borate, 0.85-1.95% of releasing agent, 12-20% of glass sand and 0.55-1.55% of coupling agent KH-55. The method is reasonable and clear in proportion, and a product is high in strength.
Description
Technical field:
The present invention relates to auto parts and components casting technology field, be specifically related to a kind of front cover of minibus.
Background technology:
Do not have outstanding engine bin and storage room before and after minibus refers to, the vehicle as a loaf of bread is referred to as.Last century late nineteen seventies early eighties, the minibus of CONTINENTAL AREA OF CHINA is far from, and today, so style was rich and varied, was mostly the shape of a cuboid.And during this period of time from Japanese import some " tool cars ", the vehicle before being there not being China's Mainland, everybody feels to resemble very much bread on the market at that time, outstanding warehouse is not had before and after adding, just as the bus reduced, the pronunciation of " Minibus " is also similar to " bread ", and just got the nickname of " minibus ", the call of " tool car " has all been substituted gradually.Main vehicle is all generally made in China, as golden cup, in suitable, Chang'an, Song Hua River, Chang He, five water chestnuts etc.
The front cover of minibus is smaller, produce relatively simple than the protecgulum of the vehicles such as common car, SUV when producing, but due to the importance of protecgulum, the process of producing is remarkable, and now many front covers all can have use PVC material, although price is very cheap, the difference all very such as security performance.
Summary of the invention:
Technical problem to be solved by this invention is to overcome the front cover that existing technological deficiency provides a kind of minibus that a kind of method is reasonable, proportioning is clear, product strength is high.
Technical problem to be solved by this invention adopts following technical scheme to realize:
A front cover for minibus, is characterized in that: each component proportion is as follows in weight fraction,
A kind of preparation method of front cover of minibus comprises,
I by paraffin make need model and running channel by Al
2o
3be fused into liquid;
Paraffin is placed in running channel by II, is coated with one deck inner pattern releasing agent applicable in paraffin surface, then at parcel one deck glass sand;
III pours molten steel and phenolic resins into immediately, mixed-forming after II completes in running channel;
Material after shaping is put into baking machine by IV to be toasted, and when after melted paraffin wax, then pours Al into
2o
3liquid, continue baking 10 minutes, baking temperature is the typical baking temperatures of steel, the 7th minute time, add potassium borate;
Material after baking in IV takes out by V, puts into coupling agent KH-550, then to be placed in condensation room condensation 10 minutes, and temperature is 0 DEG C, adds carbonic hydroammonium again after condensation;
VI carries out sanding and polishing by putting into polishing machine after condensation of material again.
Beneficial effect of the present invention is: product strength of the present invention is high, uses two kinds of different metallic solutions to coordinate other material again, makes the physical property of material superior like this, and security performance increases.The inventive method is reasonable, proportioning is clear, product strength is high.
Detailed description of the invention:
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, setting forth the present invention further below.
A front cover for minibus, is characterized in that: each component proportion is as follows in weight fraction,
A kind of preparation method of front cover of minibus comprises,
I by paraffin make need model and running channel by Al
2o
3be fused into liquid;
Paraffin is placed in running channel by II, is coated with one deck inner pattern releasing agent applicable in paraffin surface, then at parcel one deck glass sand;
III pours molten steel and phenolic resins into immediately, mixed-forming after II completes in running channel;
Material after shaping is put into baking machine by IV to be toasted, and when after melted paraffin wax, then pours Al into
2o
3liquid, continue baking 10 minutes, baking temperature is the typical baking temperatures of steel, the 7th minute time, add potassium borate;
Material after baking in IV takes out by V, puts into coupling agent KH-550, then to be placed in condensation room condensation 10 minutes, and temperature is 0 DEG C, adds carbonic hydroammonium again after condensation;
VI carries out sanding and polishing by putting into polishing machine after condensation of material again.
More than show and describe general principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
