Abstract
The invention relates to a surface sand blasting method for a die casting mold. The method is characterized by comprising the following steps of: firstly, after the manufacture of a mold core of the die casting mold is finished, placing the mold core into a sand blasting machine, and protecting an area which is not subjected to sand blasting; secondly, loading sand blasting particles with the diameters of 0.1 to 0.3mm into the sand blasting machine to get ready for sand blasting; thirdly, performing sand blasting on the mold core of the die casting mold by using the sand blasting machine; fourthly, removing the protection over the mold core of the die casting mold; and finally, placing the mold core subjected to the sand blasting into a mold frame to finish the sand blasting of the mold. Therefore, the inner cavity plane of the mold (the outer plane of a product) can be effectively subjected to sand blasting treatment (etching), and the surface of the product molded by the mold subjected to the sand blasting has a frosted effect which is the same as that achieved by performing the sand blasting on the surface of the product. In addition, the mold core can be protected from being quickly eroded, so that the abrasion resistance of the mold can be enhanced, and the service life of the mold is further prolonged.
Description
Technical field
The present invention relates to a kind of die processing method, relate in particular to a kind of die casting surface sand-blasting method.
Background technology
In existing die casting production process, it usually all has washmarking piebald and cold shut line in appearance the die casting of writing board shape, influences so very much the product appearance quality.Simultaneously, often can not be received, can think that the quality of product does not reach assurance by the purchaser for some darker cold shut lines.So just increased the step of selecting.And, must pass through sandblast for product and could eliminate with washmarking piebald and cold shut line.And for this universal phenomenon, all often die castings all need sandblast whole machining process technology, have promoted the fussy degree of processing thus, have slowed down operating efficiency, have also improved the cost of making.
Summary of the invention
The object of the invention is exactly the problems referred to above that exist in the prior art in order to solve, and a kind of die casting surface sand-blasting method is provided.
The object of the invention is realized through following technical scheme:
Die casting surface sand-blasting method, it may further comprise the steps: 1. step after the mould heart of compression mod completes, puts into sand-blasting machine with the mould heart, and the zone that does not need sandblast is protected; Step 2., the diameter of packing in sand-blasting machine the inside is the sandblast particle of 0.1～0.3mm, the preparation sandblast; 3. step through sand-blasting machine, carries out sandblast facing to the mould heart of compression mod; 4. step removes the protection of the compression mod mould heart; Step 5., with the mould heart that has sprayed sand be put into framed in, mould is accomplished sandblast.
Above-mentioned die casting surface sand-blasting method, wherein: the 1. described protection of step hides paper for employing or fig leaf hides.
Further, above-mentioned die casting surface sand-blasting method, wherein: the glass sand that the 2. described sandblast particle of step is diameter 0.2mm.
Again further, above-mentioned die casting surface sand-blasting method, wherein: the 3. described sandblast process of step is carried out the evenly sandblast of formula of surface for the mould heart to compression mod needs the zone of sandblast.
The advantage of technical scheme of the present invention is mainly reflected in: can effectively be directed against dies cavity plane (product outerplanar) and carry out blasting treatment (etching); The product that mould molding after the sandblast comes out will be the sensation that the surface has a kind of frosted, with the same in product surface sandblast effect.Simultaneously, can protect the mould heart can very fast not washing away, strengthen the wearability of mould, thereby improve die life.And, adopt the present invention can also reduce the step of carrying out sandblast on the product after adopting Mould Machining, can when shortening operation, practice thrift cost.
The object of the invention, advantage and characteristics will make an explanation through the non-limitative illustration of following preferred embodiment.These embodiment only are the prominent examples of using technical scheme of the present invention, and all technical schemes of taking to be equal to replacement or equivalent transformation and forming all drop within the scope of requirement protection of the present invention.
The specific embodiment
Die casting surface sand-blasting method, its unusual part is may further comprise the steps: at first, after the mould heart of compression mod completes, the mould heart is put into sand-blasting machine, the zone that does not need sandblast is protected.Specifically, in order to improve the effect of covering, effective isolation is the most carried out in the zone that does not need sandblast, the protected mode that the present invention adopted is to adopt covering paper or fig leaf attached to the zone that does not need sandblast.And, consider adhere to effective, can adopt covering paper or fig leaf with certain viscosity, also can not come off even receive the impact of sandblast like this, guarantee to protect perfect.
Afterwards, the diameter of packing in the sand-blasting machine the inside is the sandblast particle of 0.1～0.3mm, the preparation sandblast.From the present invention's one preferred implementation, the sandblast particle of employing is the glass sand of diameter 0.2mm.Thus, can come effectively to remove washmarking piebald and cold shut line through glass sand.
Then, through sand-blasting machine, the mould heart that faces toward compression mod carries out sandblast.In this process; In order to promote removal effect to washmarking piebald and cold shut line; And avoid the improper mould heart to compression mod of sandblast to cause the sandblast accidental damage, the sandblast process that the present invention adopted is carried out the evenly sandblast of formula of surface for the mould heart of compression mod being needed the zone of sandblast.Thus, can be from the secondary injury of avoiding the sandblast inequality that the mould heart is brought to the full extent.
Then, remove the protection of the compression mod mould heart.In other words, tear off and hide paper or fig leaf gets final product.
At last, with the mould heart that has sprayed sand be put into framed in, mould had both been accomplished whole sandblast process.
Can find out through above-mentioned character express; After adopting the present invention; Can effectively be directed against dies cavity plane (product outerplanar) and carry out blasting treatment (etching), the product that the mould molding after the sandblast comes out will be the sensation that the surface has a kind of frosted, with the same in product surface sandblast effect.Simultaneously, can protect the mould heart can very fast not washing away, strengthen the wearability of mould, thereby improve die life.And, adopt the present invention can also reduce the step of carrying out sandblast on the product after adopting Mould Machining, can when shortening operation, practice thrift cost.
