电铸倒钩模具，将铝块电铸于需要加工倒钩结构的产品模具内；Electroforming barb mold, electroforming the aluminum block into the product mold that needs to process the barb structure;
成型倒钩结构，将液体塑胶灌注于产品模具中进行倒钩成型；The barb structure is formed, and the liquid plastic is poured into the product mold to form the barb;
溶解倒钩模具，使用溶液将铝块腐蚀。The barb mold is dissolved and the aluminum block is etched with the solution.
优选的，所述溶液为氨基磺酸盐镀镍溶液。Preferably, the solution is a sulfamate nickel plating solution.
优选的，所述产品模具为铁制模具。Preferably, the product mold is an iron mold.
优选的，所述加工倒钩模具步骤和所述电铸倒钩模具步骤之间，还包括：Preferably, between the step of processing the barb mold and the step of electroforming the barb mold, further comprising:
物理抛光步骤，将铝块的凹槽用砂带条对凹槽内壁进行抛光。In the physical polishing step, the groove of the aluminum block is polished with an abrasive strip to the inner wall of the groove.
综上所述，本发明具有以下有益效果：通过在铝块上加工与需要产品的倒钩结构匹配的凹槽，能够提高模具的一体性，使得倒钩结构完全由铝块内的凹槽灌注液体塑胶成型，形成的倒钩结构平整，提高了产品质量；另外，通过溶液将铝块进行腐蚀，避免了脱模时拆除倒钩模具损伤产品的问题，进一步提高了产品质量。To sum up, the present invention has the following beneficial effects: by processing grooves on the aluminum block that match the barb structure of the required product, the integrity of the mold can be improved, so that the barb structure is completely filled with the grooves in the aluminum block. Liquid plastic molding, the formed barb structure is flat, and the product quality is improved; in addition, the aluminum block is corroded by the solution, which avoids the problem of removing the barb mold and damages the product during demoulding, and further improves the product quality.
