Solid-liquid double-layer extensible flexible bearing device of mold

Abstract

A solid-liquid double-layer extensible flexible bearing device of a mold comprises a container, a support, a rope and a fixing device, wherein the container is used for containing liquid. The support is of a hollow tubular structure and is arranged in the container, the edges at the upper end of the support are recessed at intervals to form a plurality of notches, and the top of the support is used for soft solids to be placed on. One end of the rope is fixed on one side of the top end of the support, and the other end of the rope penetrates through a hole arranged on the other side of the top end of the support and then penetrates through a small hole arranged on the upper portion of the lateral wall of the container. The fixing device is arranged on the outer side of the container close to the small hole. The solid-liquid double-layer extensible flexible bearing device of the mold can prevent bubbles from accumulating between the upper-layer soft solids and the lower-layer liquids, can prevent the upper-layer soft solids from recessing downwards during experiments, accordingly can reduce errors caused by mold deformation and bubble accumulation, and therefore experiment results are led to be accurate. In addition, the solid-liquid double-layer extensible flexible bearing device of the mold further has the advantages of being reasonable and simple in structural design, simple in operation method and the like.

Description

technical field [0001] The invention belongs to the technical field of teaching and scientific research experimental devices, in particular to a retractable and flexible bearing device of a solid-liquid double-layer model. Background technique [0002] In teaching and scientific research, in order to carry out optical experiments such as light reflection and refraction, it is often necessary to prepare solid-liquid double-layer models. The upper layer of this solid-liquid bilayer model is soft solid, the lower layer is liquid, and the upper and lower layers are closely connected. However, since the lower layer of liquid cannot support the upper layer of soft solid, it is necessary to provide a bearing device for supporting the solid-liquid double-layer model. The existing solid-liquid double-layer model bearing device has the following problems: 1. It is easy to make the soft solid on the upper layer sag downward, thereby causing distortion of optical measurement. 2. Bubbl...

Problems solved by technology

The existing solid-liquid double-layer model bearing device has the following problems: 1. It is easy to make the soft solid on the upper layer sag downward, thereby causing distortion of optical measurement

2. Bubbles are easy to accumulate between the upper layer of soft solid and the lower layer of liquid. As a result, the two layers are not always closely connected, which will lead to measurement errors
