Problems solved by technology

[0003] In the prior art, experimental molds for making standard test pieces of similar materials generally adopt a split-type combined structure. During use, it is often necessary to fill the test piece with the inside of the mold first, and then demould it when it is naturally dried to a certain extent. , the specimens are placed in a drying oven for heating and drying after demolding, but this experiment is very time-consuming, and the number of specimens that can be placed in the drying oven is also a certain amount, which brings great benefits to similar material simulation experiments. great inconvenience

Embodiment 1

[0031] like figure 1 and image 3 The shown rapid prototyping equipment for a test piece of a standard similar material includes a forming base 1 and a forming die 2 arranged on the base 1. The forming model is confirmed according to the shape and size of the test piece to be formed. In this embodiment, The forming mold is a cylindrical mold, specifically, the cylindrical mold is made of such as Figure 4 The two half-cylindrical shells shown are snapped together, and the two half-cylindrical shells are fixedly connected by nuts 4, the two half-cylindrical shells are identical two half-cylindrical shells, and the inner surface of each half-cylindrical shell The surface is smooth and easy to demould. Nuts are fixed on the side edges of each semi-cylindrical shell. After fastening the two semi-cylindrical shells, the nuts on the two semi-cylindrical shells are in direct contact, and then the connecting bolts are inserted into the Connect the two semi-cylindrical shells to the ...

Abstract

The invention relates to a rapid molding device and method for a standard similar material test piece. The molding device comprises a molding base and a molding die arranged on the base. The molding die is sleeved with a heating and drying coat for heating the test piece filled in the molding die, the inner wall of the heating and drying coat device makes contact with the inner wall of the moldingdie, the bottom of the heating and drying coat device is located on the upper surface of the base, and the heating and drying coat device is connected with a temperature and an electric heating plug.The molding die and the heating and drying coat device can be produced and used in a matched way, so that preparation time of similar material test piece can be prolonged; multiple heating and dryingcoat layer devices can be used for heating and drying a group of mold test pieces at the same time, and the heating and drying coat layer devices are recycled after heating and drying are completed;and the rapid molding device and method are characterized by being simpler in structure, shorter in consumed time, capable of realizing batch production and the like.

Description

technical field [0001] The invention relates to the technical field of material simulation experiments, in particular to a rapid prototyping equipment and a prototyping method for standard similar material test pieces. Background technique [0002] As mining gradually develops deeper, its complexity gradually increases, which intensifies the requirements of indoor physical tests, especially the application of similar simulation materials. Indoor physical similarity simulation experiment is an important means of simulating the movement and space-time evolution of the macroscopic physical field. According to the actual geological conditions, the test piece is reduced to a certain proportion for simulation experiments, and the deformation, displacement, damage, etc. of the test piece are observed, and the analysis test is recorded. The physical and mechanical properties of the parts reflect the changes in the mechanical properties of the geology and the multi-field coupling eff...
