Description
Technical Field
The invention relates to the technical field of barb forming, in particular to an electroforming process for forming barbs.
Background
In the injection molding process, because the mold is poor in integrity, burrs are easily generated in the traditional preparation process when the barb structure is formed in the mold cavity, the barb structure formed by a product is uneven, and the product quality is affected.
Disclosure of Invention
In view of the above-mentioned deficiencies of the prior art, it is an object of the present invention to provide an electroforming process for forming barbs, which has the advantages of smooth structure of the formed barbs and improved product quality.
The technical purpose of the invention is realized by the following technical scheme: an electroforming process for forming barbs, comprising the steps of:
processing a barb die, and processing a groove matched with a barb on a product on an aluminum block;
electroforming a barb mold, namely electroforming an aluminum block in a product mold needing to process a barb structure;
forming barb structure, pouring liquid plastic into product mould to make barb forming;
the barb mold is dissolved and the aluminum block is etched using a solution.
Preferably, the solution is a sulfamate nickel plating solution.
Preferably, the product mold is an iron mold.
Preferably, between the step of processing the barb mold and the step of electroforming the barb mold, the method further comprises:
and a physical polishing step, namely polishing the inner wall of the groove of the aluminum block by using abrasive belt strips.
In conclusion, the invention has the following beneficial effects: the grooves matched with the barb structures of the products to be produced are processed on the aluminum block, so that the integrity of the die can be improved, the barb structures are completely formed by filling liquid plastic into the grooves in the aluminum block, the formed barb structures are smooth, and the product quality is improved; in addition, the aluminum block is corroded through the solution, the problem that the barb mold is detached to damage a product during demolding is avoided, and the product quality is further improved.
Detailed Description
An electroforming process for forming barbs, comprising the steps of:
processing a barb die, and processing a groove matched with a barb on a product on an aluminum block;
electroforming a barb mold, namely electroforming an aluminum block in a product mold needing to process a barb structure;
forming barb structure, pouring liquid plastic into product mould to make barb forming;
the barb mold is dissolved and the aluminum block is etched using a solution.
The grooves matched with the barb structures of the products to be produced are processed on the aluminum block, so that the integrity of the die can be improved, the barb structures are completely formed by filling liquid plastic into the grooves in the aluminum block, the formed barb structures are smooth, and the product quality is improved; in addition, the aluminum block is corroded through the solution, the problem that the barb mold is detached to damage a product during demolding is avoided, and the product quality is further improved.
Specifically, the solution is a sulfamate nickel plating solution.
Specifically, the product mold is an iron mold.
Specifically, between the step of processing the barb mold and the step of electroforming the barb mold, the method further comprises the following steps of:
and a physical polishing step, namely polishing the inner wall of the groove of the aluminum block by using abrasive belt strips. Therefore, the smoothness of the inner wall of the inner groove of the aluminum block is further improved, and the quality of products is indirectly improved.
The above-mentioned embodiments are merely illustrative and not restrictive, and those skilled in the art can make modifications to the embodiments without inventive contribution as required after reading the present specification, but only protected by the patent laws within the scope of the claims.
