Abstract
The invention belongs to technical field of surface, disclose a kind of surface treatment method of die casting, including check whether die casting is qualified, if so, being placed into the positional stations in sandblasting seal chamber；Abrasive blast equipment is opened, positional stations of the material into the sandblasting seal chamber will be cut using compressed air and sprayed；Meanwhile water mist is sprayed into the sandblasting seal chamber using High temperature ion atomizer；Cooling treatment, the technical solution is suitable for producing the die casting finished product with metal-like or high texture effect on die casting surface, and manufactured die casting finished product corrosion resistance is preferable, be conducive to cover the flaw on die casting surface, conducive to raising die casting finished product yield, production is high, is suitable for industrial mass production.
Description
Technical field
The present invention relates to technical field of material surface treatment, in particular to a kind of surface treatment method of die casting.
Background technique
Die casting is a kind of metal casting technique, its main feature is that applying high pressure to molten metal using mold cavity.Die casting tool
Have the advantages that high production efficiency, it is at low cost, can produce that complex component, application range of products are wide and production capacity is abundant.Most of pressures
Casting casting is all free from iron, such as zinc, copper, aluminium, magnesium, lead, tin and terne metal and their alloy.When die casting is answered
When for appearance ornamental pieces, it is primarily present two problems:
1, alloy for die casting material, which just determines die casting not, can be carried out high-quality sense surface treatment, and such as common die casting aluminium closes
Gold can not carry out anode dyeing；Diecast magnesium alloy chemical property is active, corrosion resistance is poor, it is necessary to by spray painting or the methods of pad pasting into
The surface treatment of row exterior trimming parts, however die casting can be made to lose metal-like in this way.
2, die casting has an intrinsic, inevitable defects of die casting, and such as stomata crackle, is mingled with, local dent and current mark
Deng, these defects become difficult subsequent processing procedure, while also make die casting finished product yield reduction.
Summary of the invention
In order to solve problems in the prior art, the embodiment of the invention provides a kind of surface treatment methods of die casting, fit
For producing the die casting finished product with metal-like or high texture effect, and manufactured die casting finished product corrosion resistant on die casting surface
Corrosion is preferable, is conducive to the flaw for covering die casting surface, is conducive to improve die casting finished product yield, production is high, and it is big to be suitable for industry
Amount production.
In order to achieve the above objectives, technical solution of the present invention is as follows:
A kind of surface treatment method of die casting, comprising the following steps:
Check whether die casting is qualified, if so, being placed into the positional stations in sandblasting seal chamber；
Abrasive blast equipment is opened, positional stations of the material into the sandblasting seal chamber will be cut using compressed air and sprayed；
Meanwhile
Water mist is sprayed into the sandblasting seal chamber using High temperature ion atomizer；
Cooling treatment is carried out to previous step treated die casting.
Specifically, described to cut the Emery grains sand that material is 60 mesh.
Technical solution provided in an embodiment of the present invention the utility model has the advantages that
1, the present invention is suitable for producing the die casting finished product with metal-like or high texture effect on die casting surface, and
Manufactured die casting finished product corrosion resistance is preferable.
2, manufacture craft of the invention is simple, is conducive to the flaw for covering die casting surface, and it is good to be conducive to raising die casting finished product
Rate, production is high, is suitable for industrial mass production.
3, manufacture craft of the invention makes the surface of workpiece obtain certain cleannes and different roughness, makes workpiece table
The mechanical performance in face is improved, therefore improves the fatigue resistance of workpiece, increases its adhesive force between coating, is extended
The durability of film, is also beneficial to the levelling and decoration of coating, the impurity on surface, variegated and oxide layer is disposed, simultaneously
It is roughened dielectric surface, eliminate workpiece residual stress and improves the effect of substrate surface hardness.
Detailed description of the invention
To describe the technical solutions in the embodiments of the present invention more clearly, make required in being described below to embodiment
Attached drawing is briefly described, it should be apparent that, drawings in the following description are only some embodiments of the invention, for
For those of ordinary skill in the art, without creative efforts, it can also be obtained according to these attached drawings other
Attached drawing.
Fig. 1 is a kind of flow diagram of the surface treatment method of die casting provided in an embodiment of the present invention.
Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with attached in the embodiment of the present invention
Figure, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is only this
Invention a part of the embodiment, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art exist
Every other embodiment obtained under the premise of creative work is not made, shall fall within the protection scope of the present invention.
Working principle: blasting craft is that compressed air is used to form high velocity spray beam for power, and the high speed such as material spray is sprayed
To workpiece surface need to be handled, the appearance of outer surface of workpiece is made to change, since abrasive material makees the impact of workpiece surface and cutting
With making workpiece surface obtain certain cleannes and different roughness, improve the mechanical performance of workpiece surface, this reality
The surface treatment method for applying a kind of die casting of example offer is exactly to be surface-treated using the principle to die casting surface, is improved
Its surface defect.
A kind of surface treatment method of die casting, refering to what is shown in Fig. 1, the following steps are included:
Check whether die casting is qualified, if so, being placed into the positional stations in sandblasting seal chamber；
Abrasive blast equipment is opened, positional stations of the material into the sandblasting seal chamber will be cut using compressed air and sprayed；
Meanwhile
Water mist is sprayed into the sandblasting seal chamber using High temperature ion atomizer；
Cooling treatment is carried out to previous step treated die casting.
Specifically, described to cut the Emery grains sand that material is 60 mesh.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all in spirit of the invention and
Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
