A rapid prototyping method for similar simulated material molding die assembly and its standard test piece

Abstract

The invention discloses a rapid prototyping method for a molding die assembly of a similar simulated material and a standard test piece thereof, wherein the molding die assembly of a similar simulated material includes four parts: a base, a large ferrule, an inner mold and a small ferrule, and a A circular pressure-bearing cover plate with a cylindrical protrusion in the center; the bottom of the inner mold and the bottom plate form an interference fit plug, and the size of the ferrule is a loop-type structure, which is directly fitted on the outer wall of the inner mold. The circular pressure-bearing cover plate The pressure of the press can be effectively transmitted to similar materials in the cavity of the inner mold, and the large and small ferrules can be prevented from retreating. Its structure is simple, easy to assemble and disassemble; the similar simulation material forming mold assembly of the present invention is used in the rapid prototyping method of the standard test piece, and its operation is simple and easy, the quality of the prepared test piece is stable, the consistency is good, suitable for batch similar Rapid prototyping of standardized test pieces for simulated materials.

Description

technical field [0001] The invention relates to a simulation experiment device and an experiment method thereof, in particular to a similar simulation material molding die assembly and a method for making a similar material standard test piece. Background technique [0002] The indoor physical similarity simulation test is an important means to simulate the movement and space-time evolution of the macroscopic physical field. Among them, the test of the mechanical properties of similar materials is an important indicator to verify whether the material is suitable. [0003] In the prior art, test molds for making standard test pieces of similar materials generally adopt a split-type combined structure. During use, clamps or other fasteners need to be used to fasten them into one body (after use, loosen the fasteners to remove them) mold). However, after the similar material is filled, during the loading process on the press, due to the extrusion process of the similar materi...

Problems solved by technology

[0005] However, the fly in the ointment is that the reserved chamber of the above-mentioned technical solution simulates the test piece to prepare the mold assembly. First, the processing and manufacturing of the second clamp is difficult and costly; second, the disassembly and assembly of the mold is relatively complicated and cannot It is suitable for rapid prototyping of batch test pieces; third, once there is a misoperation such as excessive loading pressure of the press, it is easy to cause damage to the two clamps
