Description
Technical field
The present invention relates to a kind of die surface of the automobile-used rubber blanket product surface quality of improvement for auto industry field
Processing method.
Background technology
With the improvement of people ' s living standards, the development of automobile is advanced by leaps and bounds, and drives comfortableness, peace that people drives to automobile
The standard more and more higher of full property and applicability, these demands also propose requirement higher to Automobile Design.Automobile-used rubber blanket master
If being arranged on Automobile Dashboard, storage tank and console position, anti-skidding and beauty function is primarily served.Automobile-used rubber blanket master
TPV or TPE analog thermoplastic elastomer material manufactures, the material of the type are used often due to strand is long, it is intermolecular
Active force is big, and when being heat-treated, the mobility of material solution is often bad, and TPV or TPE are received in screw in injection molding machine
Air bubble cladding is easily produced during hot shearing in the material, its injection molding is affected.The injection of traditional handicraft
In production process, TPV or TPE solutions are not enough in mold cavity internal mobility, again due to die surface ratio during mould filling
It is more smooth, so solution is hardly formed rolling, mainly based on forward slip, it is difficult to once air bubble is coated in solution
It is excluded, this can cause product surface the defect phenomenons such as material flower, current mark occur, reduce job efficiency, cause material
The waste of material and production cost are improved.
The content of the invention
The invention aims to overcome the deficiencies in the prior art, there is provided one kind improves automobile-used rubber blanket product surface matter
The die surface processing method of amount, it can increase the roughness of die surface, change TPV or TPE melt flow modes, so that
Improve injection product surface qualification rate.
Realizing a kind of technical scheme of above-mentioned purpose is：A kind of die surface for improving automobile-used rubber blanket product surface quality
Processing method, comprises the following steps：
Step 1, polishing step；The three kinds of sand paper for constantly being increased using mesh number successively carry out three throwings to mould inner surface
Light；
Step 2, sandblasting step；Suck diamond dust using mould sand-blower is carried out at sandblasting to the die surface that polishing is finished
Reason；
Step 3, cleanup step；Cleaning agent is dipped using hairbrush to scrub the die surface after sandblasting, clean out table
The remaining particle in face, then sandblasting face is carried out with high pressure air rifle blow afloat cleaning；
Step 4, detecting step detects the roughness of mould inner surface.
Further, the step 1, polishing step, successively using the sand paper of 400#, 600# and 800# to mould inner surface
It is polished.
Further, the step 1, polishing step, when the sand paper of different model is used instead, 45 ° of polishing direction change-
90°。
Further, the step 1, polishing step before using the sand paper of different model instead every time, uses 100% pure cotton
Flower picks cleaning solution and polished surface is wiped.
Further, the cleaning solution is kerosene.
Further, for the step 2, sandblasting step carries out blasting treatment using 45# diamond dust.
A kind of die surface processing method for improving automobile-used rubber blanket product surface quality of the invention, by mould table
The blasting treatment in face, makes die surface produce fine irregularities to change, and increases the mantle friction of mould；When injected plastics material solution is in mould
In tool cavity during flowing filling, the frictional force of increase can make solution form Rolling flow, the air of cladding in discharge solution, so that
The defect of product surface current mark and material flower is improved, job efficiency is improved.
Specific embodiment
In order to be able to preferably understand technical scheme, carried out in detail below by specifically embodiment
Explanation：
The technique of original mould surface treatment, the not no handling process comprising sandblasting, such die surface can be relatively smooth, makes
Solution is based on forward slip flowing when being filled in mold cavity into TPV or TPE solutions, if cladding air forms gas in solution
Bubble, such motor pattern cannot discharge air, so as to influence the quality of production.
A kind of die surface processing method for improving automobile-used rubber blanket product surface quality of the invention, including following step
Suddenly：
Step 1, polishing step, successively using 400#, 600#, 800# sand paper, is polished to mould inner surface, removes oxygen
Change layer so that treat sand blasting mould surface cleaning, be controlled beneficial to sandblasting effect.Whenever the sand paper of different model is used instead,
Polishing direction distinguishes by changing 45 ° -90 °, the striped shade left after such former model sand paper polishing, also favorably
In increase die surface friction, beneficial to the absorption of follow-up sandblasting.Every time before different model sand paper is changed, it is necessary to pure with 100%
The cleaning solution that cotton picks kerosene etc carries out careful wiping to polished surface, because any small gravel in die surface
Residual can all destroy subsequent whole polishing operation, and follow-up sandblasting operation.
Step 2, sandblasting step, to step 1 polishing, good mould uses mould sand-blower, using suction-type injection side
Formula, i.e., using compressed air, flow at high speed forms negative pressure and produces ejector action in spray gun, by the 45# diamond dust in separator case
Abrasive material is drawn into spray gun by sebific duct, is then ejected into die surface by nozzle at high speeds with compressed air, produces die surface
Product raised and concave figures.
Step 3, cleanup step, first using artificial manual mode, after dipping cleaning agent to sandblasting using hairbrush
Die surface is scrubbed, and cleans out the particle of surface residual, then with high pressure air rifle sandblasting face is carried out blowing afloat cleaning again.
Step 4, detecting step, detect mould inner surface roughness whether reach design requirement, such as it is below standard, then need into
The secondary sandblasting of row.
The frictional force of die surface can be increased by the concaveconvex structure of the die surface of sandblasting so that the stream on solution upper strata
Dynamic speed is quick-frozen with the flowing of die surface contact surface higher than solution, and rolling stream is produced when causing solution to be filled in mold cavity
Dynamic phenomenon, is conducive to the discharge of the air of cladding in solution, so that the very big current mark that must reduce automobile-used rubber pad product surface
Or material flower defect, job efficiency is improved, reduce production cost.
Those of ordinary skill in the art it should be appreciated that the embodiment of the above be intended merely to explanation the present invention,
And be not used as being limitation of the invention, as long as in spirit of the invention, the change to embodiment described above
Change, modification will all fall in the range of claims of the present invention.
