EPP mould surface veins casting technique

Abstract

The invention discloses a casting process for an EPP mould surface dermatoglyph, which is characterized in that a wooden pattern is manufactured at first, then, materials with dermatoglyph are cut and smoothly pasted in the relevant position of the wooden pattern; the foam plastic mould casting is cast by adopting vacuum negative pressure finally. By adopting the way that the wooden pattern is processed in CNC method, both the precision and the workpiece precision are high; by adopting the way that the materials with dermatoglyph is pasted on the wooden pattern, the fabrication cost of the dermatoglyph is considerably reduced; and by adopting the casting method of vacuum casting process, the EPP mould surface dermatoglyph casting process of the surface with dermatoglyph can be obtained so that the compactness of products is good. Therefore, the overall technological process saves the cost and has an obvious effect, particularly when one mold generates a plurality of cavities.

Description

technical field [0001] The invention relates to a casting process with leather texture on the surface of an EPP mold, in particular to a method for casting a material with leather texture on a wooden mold and then adopting a vacuum casting process. Background technique [0002] At present, the production method of EPP mold surface texture on the market is to chemically corrode the pattern on the surface after the workpiece is processed. The cost is quite expensive, and there must be no abnormality, otherwise it will be scrapped. Contents of the invention [0003] The main task of the present invention is to provide a kind of EPP mold surface texture casting process, specifically a kind of material that adopts the leather texture on the wooden mold, and then adopts the method of vacuum casting process to obtain the EPP mold surface with the surface texture Leather casting process. [0004] In order to solve the above technical problems, a kind of EPP mold surface texture c...
