Problems solved by technology
At present, an integral type core is generally used to manufacture artificial rock cores. However, because the artificial rock core produces adhesion to the core surface and the volume expansion of the solidified resin exerts pressure on the core, the artificial core clamps the core, making it Unable to remove the mold smoothly, if the core is taken out forcibly by knocking the core from the end face, it may cause damage to the artificial core

Abstract
The invention discloses an artificial rock core casting mold with a supporting mechanism. The artificial rock core casting mold comprises a groove base, an inner tube, a supporting mechanism, an outer tube and a cover plate; an annular groove is formed in the groove base; one end of the inner tube is installed in the annular groove, the inner tube comprises a first inner tube tile and a second inner tube tile, and the first inner tube tile is connected with the second inner tube tile through an oblique surface; the supporting mechanism comprises a main supporting pipe and at least two arc rods, which are hinged to the main supporting pipe, and each arc rod is detachably installed on the inner wall of the inner tube; one end of the outer tube is fixedly installed on the groove base, and a mold cavity is formed between the outer tube and the inner tube. The other end of the outer tube is fixedly installed on the cover plate; the cover plate is installed at the other end of the inner tube in a sleeving mode. The spliced inner tube which can be easily disassembled is adopted, and the inner tube is fixed and supported by virtue of the supporting mechanism, so that success in mold stripping can be realized, and the quality of an artificial rock core can be guaranteed.
Description
technical field [0001] The invention belongs to the technical field of casting molds, in particular to an artificial rock core casting mold with a support mechanism. Background technique [0002] When extracting underground crude oil, in order to filter a large amount of impurities and particulate matter, the artificial core is generally covered with the downhole oil extraction pipe of the oil field. The artificial rock core is formed by using different particle sizes of gravel and special resin at about 80°, heat preservation for more than 20 hours. At present, an integral type core is generally used to manufacture artificial rock cores. However, because the artificial rock core produces adhesion to the core surface and the volume expansion of the solidified resin exerts pressure on the core, the artificial core clamps the core, making it It cannot be demoulded smoothly, and if it is forcibly taken out by knocking the core from the end face, it may cause damage to the arti...
