Description

A kind of preparation method of minibus front cover

Technical field:

The present invention relates to auto parts and components casting technology field, be specifically related to a kind of preparation method of minibus front cover.

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 preparation method that existing technological deficiency provides a kind of minibus front cover that a kind of method is reasonable, simple to operate, product strength is high.

Technical problem to be solved by this invention adopts following technical scheme to realize:

A preparation method for minibus front cover, is characterized in that: comprise the following steps,

Step one, design shape: the model and the running channel that make different pattern as required;

Step 2, selection sand: select high temperature resistant sand, add C5 Petropols in high temperature resistant sand, then mix bi-material concussion in earthquake equipment;

Step 3, analogue formation: make shaping by the model paraffin designed, be then placed on ventilation, shady and cool local airing 1-2 days;

Step 4, making front cover:

The model made places by I, rotational model and be coated on model by glass sand, makes glass sand be attached to model surface;

The model made in I is put into running channel by II, makes it shaping pouring into molten steel in running channel;

Step 5, baking front cover: the front cover after shaping is put into baking box and toasts, the temperature of baking is at 399-421 DEG C, and baking 47-62 minute, makes melted paraffin wax become liquid;

Step 6, packing material: filling aluminum water in the front cover of step 5, until fill up, it is shaping then to put into the condensation of condensation room;

Step 7, grinding machine protecgulum: condensed front cover is left standstill 20 minutes, then puts into grinding apparatus, in grinding apparatus, add the sand chosen in step 2, polished by sand, polishing 14-20 minute; Rinse blast pipe: taken out by the blast pipe after polishing, then use distilled water flushing blast pipe 2-4 minute;

Step 8, cleaning cart protecgulum: the front cover after polishing is taken out, then uses distilled water flushing front cover 2-4 minute;

Step 9, meticulous polishing: put into after polishing machine carries out the polishing grinding become more meticulous after the front cover after flushing is left standstill 2 minutes and obtain finished product;

Step 10, inspection product: the front cover of finished product is tested, qualified packing of product warehouse-in.

Beneficial effect of the present invention is: by mold, shaping, fill, reshaping, the intensity of such product is higher, and service life also can be longer.The inventive method is reasonable, simple to operate, 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 preparation method for minibus front cover, is characterized in that: comprise the following steps,

Step one, design shape: the model and the running channel that make different pattern as required;

Step 3, analogue formation: make shaping by the model paraffin designed, be then placed on ventilation, shady and cool local airing 1-2 days;

Step 4, making front cover:

The model made places by I, rotational model and be coated on model by glass sand, makes glass sand be attached to model surface;

The model made in I is put into running channel by II, makes it shaping pouring into molten steel in running channel;

Step 5, baking front cover: the front cover after shaping is put into baking box and toasts, the temperature of baking is at 399-421 DEG C, and baking 47-62 minute, makes melted paraffin wax become liquid;

Step 6, packing material: filling aluminum water in the front cover of step 5, until fill up, it is shaping then to put into the condensation of condensation room;

Step 7, grinding machine protecgulum: condensed front cover is left standstill 20 minutes, then puts into grinding apparatus, in grinding apparatus, add the sand chosen in step 2, polished by sand, polishing 14-20 minute; Rinse blast pipe: taken out by the blast pipe after polishing, then use distilled water flushing blast pipe 2-4 minute;

Step 8, cleaning cart protecgulum: the front cover after polishing is taken out, then uses distilled water flushing front cover 2-4 minute;

Step 9, meticulous polishing: put into after polishing machine carries out the polishing grinding become more meticulous after the front cover after flushing is left standstill 2 minutes and obtain finished product;

Step 10, inspection product: the front cover of finished product is tested, qualified packing of product warehouse-in.

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.
