Method for manufacturing paper pulp molding vacuum filtration die based on SLS quick forming principle

Abstract

The invention relates to a pulp model filtering mould manufacturing method, in particular to a pulp model filtering mould manufacturing method based on the SLS quick-forming theory. The pulp model filtering mould manufacturing method based on the SLS quick-forming theory includes the steps: step 1. the design of filtering vent; step 2. the generation of an STL file; step 3. the processing of STL files: a data processing software named Magics is adopted to process the STL file of pulp model filtering mould to generate a CLI slice file used for quickly forming the pulp model filtering mould; step 4. the conversion of the CLI slice file: the CLI slice file of the pulp model filtering mould is converted to an identifiable file of a quick-forming machine and then the converted file is inputted into the quick-forming machine; step 5. the selection of sintering material, polystyrene powder or nylon powder is selected as sintering material; step 6. the setting of sintering process parameters and manufacturing; step 7. the reinforcement process: resin is painted onto surfaces of prepared prototype parts to reinforce the strength of prepared part to form the filtering mould, so as to enhance the accuracy and efficiency of pulp model filtering mould manufacturing process.

Description

technical field [0001] The invention relates to a method for manufacturing a pulp molding suction filter mold, in particular to a manufacturing method for a pulp molding suction filter mold based on the principle of SLS rapid prototyping. Background technique [0002] Rapid prototyping technology (Rapid Prototyping&Manufacturing) originated in Japan in the 1980s, and soon developed to the United States and Western Europe. This technology uses a point-by-point or layer-by-layer molding method to form complex parts or molds at one time, without any tooling, which saves manufacturing costs, shortens the manufacturing cycle, and realizes 3D manufacturing and visualization, which is beneficial to designers and manufacturers. Information exchange between people and users. The experimental research work can be completed in the design stage, reducing the experimental cycle and material consumption, so that the product design can be quickly evaluated and modified to respond to marke...

AI Technical Summary

Problems solved by technology

[0007] At present, most of the suction and filter molds in the pulp molding industry use CNC machining to produce aluminum alloy molds, which has a long development cycle and high development costs.

Since the surface of the suction filter mold needs to be covered with ventilation holes, after the mold is processed, the ventilation holes must be drilled manually, which is time-consuming and laborious.
