Multi-functional mold and method for preparing artificial core

Abstract

The invention discloses a multi-functional mold and a method for preparing an artificial core. The mold comprises a test piece pressure head, core pieces, a base and a hoop, wherein the core pieces are aligned to form a hollow cylindrical inner cavity; the hoop is adaptive to the outer part of the core piece; a base hole is formed in the base and the base hole is adaptive to the outer part of each core piece; the test piece pressure head is adaptive to the cylindrical inner cavity, scales are arranged on the test piece pressure head, a threaded hole is formed in the center position of one end surface of the test piece pressure head, a flat nut and a bore log are matched with the threaded hole, and threads matched with the threaded hole are formed at one end of the flat nut and one end of the pore log. When the artificial core is prepared, materials are weighed twice, the weight of the materials required by the a single artificial core can be determined, the accurate size can be obtained in a pressing manner by the scales on the test piece pressure head, and the prepared artificial cores are consistent in densities and sizes.

Description

technical field [0001] The invention relates to a mold, in particular to a mold and a manufacturing method for a cylindrical standard test piece. Background technique [0002] The mechanical performance parameters of materials are the basic data that must be provided for the development of physical simulation research; in addition, rock mechanical performance parameter tests are also required in the process of material research and development. Therefore, it is particularly important to make standard specimens quickly and easily to test the mechanical performance parameters of materials or to study the fracture seepage characteristics of specimens. [0003] In the manual production of standard test pieces, there are three deficiencies in the following three aspects: First, when using a pressurizing device to compact the test piece, the compaction is often terminated when the pressure is constant at a certain value for a period of time, and the uniform size of the test piece ...

Problems solved by technology

[0003] In the manual production of standard test pieces, there are three deficiencies in the following three aspects: First, when using a pressurizing device to compact the test piece, the compaction is often terminated when the pressure is constant at a certain value for a period of time, and the uniform size of the test piece cannot be guaranteed. ; Second: The configured material is poured into the abrasive tool without secondary weighing, which cannot guarantee the same density of the produced test piece; third, the common artificial core test piece has a single function of the mold, and cannot be made with holes (non-penetrating) Core specimen
