Observation method for fluid precision finishing of surfaces of micro-structures of molds

Abstract

An observation method for fluid precision finishing of surfaces of micro-structures of molds is based on a fluid flowing similar simulation method. A tiny mold structural surface is proportionally magnified, flowing states of sparse abrasive particle flows in tiny constraint flow channels are simulated, real-time image data in the flow channels are acquired and processed, and a distribution state, movement rules, typical flowing state characteristics and development trend of the sparse abrasive particle flows in environments of the tiny constraint flow channels are obtained; and experiments show that properties of forces stressed at various points in a flow channel model and properties of forces stressed at various corresponding points in a mold tiny constraint flow channel prototype are identical on the premise of meeting requirements of geometric similarity and kinematic similarity, the forces are proportional, a proportion constant keeps unchanged to optional corresponding points in two flow fields, and fluid dynamic properties of the two flow fields meet requirements of second law of flow similarity. The invention further provides an observation device for fluid precision finishing of surfaces of micro-structures of molds. The observation method and the observation device have the advantages that fluid finishing conditions and states for the surfaces of the micro-structures of molds can be well simulated, operation is simple, convenient and feasible, and universality is good.

Description

technical field [0001] The invention relates to the field of fluid precision machining, in particular to a method and device for observing fluid precision machining on the microstructure surface of a mold. Background technique [0002] Molds play an irreplaceable role in the manufacturing production chain. In the mold manufacturing process, in order to eliminate the mechanical processing traces left on the mold surface, finishing it has become a necessary process, and it will account for more than half of the entire mold manufacturing time. Existing methods generally need to contact or be close to the surface to be processed by means of a finishing tool to achieve material removal from the surface to be processed. With the continuous development of the manufacturing industry and its related supporting technologies, the application of complex cavity molds is becoming more and more widespread, but the research and development of precision finishing processing technology for v...
