A method for manufacturing an injection mold cavity with a precise simulated skin pattern surface

Abstract

The invention discloses a method for manufacturing a precise real leather-grain simulated molding surface of an injection mold cavity. The method sequentially comprises the steps of manufacturing of a raw hide model (1), manufacturing of a female die layer film (2), manufacturing of a male die electrode (3) and manufacturing of the leather-grain molding surface (4). The method comprises the technological steps that the female die layer film is obtained by using the raw hide model through an electroforming method; the male die electrode is obtained by conducting electric erosion machining on the female die layer film; and the leather-grain molding surface of the injection mold cavity is obtained by conducting electric erosion machining on the male die electrode. According to the technical scheme, the female die layer film obtained through electroforming can highly reflect the texture of real leather, so that the leather-grain molding surface is precisely simulated and duplicated. The defect that a leather-grain surface of a leather-grain simulated injection molded product lacks the texture in the prior art is overcome, so that the leather-grain surface of the leather-grain simulated injection molded product has the texture of the real leather.

Description

technical field [0001] The invention relates to a method for making an injection mold cavity, in particular to the production of an injection mold cavity with a precision imitation leather texture surface for precise profiling on the inner surface of the injection mold cavity to make a leather-patterned negative model surface method. Background technique [0002] The surface of the interior injection molding products of high-end automobiles needs imitation leather texture, which requires the inner surface of the cavity of the injection mold to make the female model surface of the artificial leather texture, and the female mold surface of the artificial leather texture is provided, referred to as the leather texture surface The prior art adopts photographic plate making, silk screen plate making, screen printing, decal transfer printing, the method of photosensitive etching, is called for short photoetching, and the inner surface of injection mold cavity is made skin pattern ...

[0002] The surface of the interior injection molding products of high-end automobiles needs imitation leather texture, which requires the inner surface of the cavity of the injection mold to make the female model surface of the artificial leather texture, and the female mold surface of the artificial leather texture is provided, referred to as the leather texture surface The prior art adopts photographic plate making, silk screen plate making, screen printing, decal transfer printing, the method of photosensitive etching, is called for short photoetching, and the inner surface of injection mold cavity is made skin pattern surface, because described photoetching obtains The skin texture surface is the plane surface of the upper and lower layers, so that microscopic observation shows that the upper surface of the skin texture of the injection molded product in the prior art is flat, and the skin texture grooves are all deep, and the gap between the skin texture upper surface and the skin texture grooves is deep. No curved surface transition, lack of the natural high and low curved surface of the dermatoglyph surface, the curved surface transition between the dermatoglyph surface and the dermatoglyph gullies, and the texture of the different depths of the dermatoglyphate grooves, that is, the genuine leather texture; therefore, the existing technology has imitation dermatoglyph Problems and deficiencies of lack of genuine leather texture on the textured surface of injection molded products
