Track plate test piece de-molding machine and test mold

Abstract

The invention provides a track plate test piece de-molding machine. The track plate test piece de-molding machine comprises a shell body, wherein the shell body is internally provided with a hoisting device, a force application device, a force transmitting device and a limiting device; the hoisting device and the force application device are vertically arranged in parallel and are connected through the force transmitting device; the hoisting device is used for providing power of movement in a vertical direction for the force application device through the force transmitting device; the limiting device comprises a supporting framework and a test mold mounting platform mounted on the supporting framework; the test mold mounting platform is arranged just above the force application device and is used for fixing the test mold; and one force in the vertical direction is additionally applied to a test piece through rotating the hoisting device to drive the force application device, so that the test piece is pushed out from the test mold. The track plate test piece de-molding machine provided by the invention is matched with the test mold, and the de-molding efficiency is high; the de-molded mold is convenient to fix and take off, and the manpower is saved; and the disadvantage that the mold is knocked by a rubber hammer and taken off is avoided, so that the taken-out test mold is more complete and a testing conclusion is more accurate.

Description

technical field [0001] The invention belongs to the innovative field of asphalt mixture test equipment, and in particular relates to a demoulding machine for a rut plate test piece and a test mold. Background technique [0002] According to JTG E20-2011 "Test Regulations for Asphalt and Asphalt Mixtures in Highway Engineering", the wheel rolling method is suitable for forming plate-shaped specimens with a length of 300mm × width 300mm × thickness 50-100mm. Before the mixture plate test piece is formed, it is necessary to lay a cut newspaper inside the test mold, so that the bottom surface and the side of the test mold are separated by paper, which is convenient for the subsequent demoulding work. [0003] The test mold selected in the current test is made of high carbon steel or tool steel. The four side plates of the test mold are connected together by bolts in pairs, and form a whole with the bottom plate respectively. When demoulding the rut specimen, the bolts need to b...

Problems solved by technology

[0005] In order to solve the waste of paper and environmental pollution caused by the prior art, it is necessary to frequently unscrew the bolts to waste time when using bolts to fix the mold test. The asphalt stuck to the bolts will seriously affect the quality of the test piece during the next use. Small compaction The long-term beating of the hammer will cause damage to the test mold and affect the internal structure of the slab rut test piece, which will affect the accuracy of the test results. The present invention provides a demoulding machine for rut test pieces and a test mold
