Manual demoulding device

Abstract

The invention belongs to the technical field of demoulding equipment in building construction, and relates to a manual demoulding device aiming at a sample with diameter of 39.1mm and height of 80mm. The main body of the manual demoulding device structurally comprises a support fixed frame, a fixed plate, an upper roof plate, an actmix threaded rod, a pressuring plate, a fixed bolt, a mould placing room, a detachable mould receiving box and a rubber cushion. A test mould is placed into the mould placing room, a glass sheet with diameter of 39.1mm is paved on the surface of the sample, the upper roof plate downwards moves to enable the circle hole center of the upper roof plate to be aligned and in tight contact with the center of the mould, then the fixed bolt is screwed down, the upper end of the support fixed frame is pressed by one hand, and the actmix threaded rod is rotated by the other hand to enable the pressuring plate to downwards move, and the sample is gradually separated from the mould and can fall into the detachable mould receiving box along the downward movement of the pressuring plate. The manual demoulding device provided by the invention is simple in preparation technology, low in cost, small in shape, convenient to place, convenient to use and high in reliability, substantive features are outstanding, and improvement is prominent.

Description

Technical field: [0001] The invention belongs to the technical field of demoulding equipment for building construction, and relates to a small manual demoulding device, in particular to a manual demoulding device for samples with a diameter of 39.1 mm and a height of 80 mm. Background technique: [0002] As the research and application of foundation treatment, alkali dregs, and reinforced soil become more and more extensive and in-depth, it is usually necessary to measure various mechanical properties of soil samples, including the determination of soil sample strength, among which the unconfined test The production of parts is an indispensable test link; demoulding is carried out after the required sample is produced, but due to the high bond strength between the sample and the mold and the small sample is prone to uneven force However, the demoulding of the sample has become a difficult problem due to damage. In reality, the use of a demoulding device has become necessary....

AI Technical Summary

Problems solved by technology

[0005] Compared with the prior art, the present invention effectively solves the demoulding problem of the sample with a diameter of 39.1mm and a height of 80mm, adopts manual operation, does not require electric power support, meets energy-saving requirements, and overcomes the shortcoming of oil leakage sometimes in hydraulic jacks. The preparation process is simple, the cost is low, the shape is small and exquisite, easy to place, easy to use, high reliability, has outstanding substantive features and significant progress
