Problems solved by technology
Molds are also needed when doing various hot-press sintering and cold-press molding experiments in the laboratory, but after the experiment is completed, due to the sample bonding on the mold and the high internal pressure, the made samples and mats Chips are not easy to take out, especially the metal mold is difficult to take out regardless of cold pressing or hot pressing sintering, which brings certain difficulties to the next experiment

Embodiment Construction
[0018] In order to better understand the technical solution of the present invention, the laboratory mold opener of the present invention will be further described below in conjunction with the accompanying drawings.
[0019] A laboratory mold opener is composed of a hydraulic jack 1, a support rod 2, a support plate 3, an inner hexagon bolt 4, a fixing screw rod 5, and a fastening nut 6. There are four threaded holes 8 under the base 7 of the hydraulic jack 1. One end of the support rod 2 has an external thread and the other end has an internal thread. The end of the support rod 2 with an external thread is installed on the base 7 of the hydraulic jack. The counterbore 12, the support plate 3 is installed on the end of the support rod 2 with internal thread through the counterbore 12 with the hexagon socket bolt 4, there are two grooved through holes 11 in the support plate 3, and the lower end of the fixing screw 5 has two protrusions The fixed end 13, the fixed end 13 is in...

A mold opening device for a laboratory is characterized by being composed of a hydraulic jack, supporting rods, a supporting disc, hexagon socket screws, fixing screw rods and fastening nuts. Four threaded holes are formed in the lower face of a hydraulic jack base. One end of each supporting rod is provided with an outer thread, and the other end of each supporting rod is provided with an inner thread. The end, with the outer thread, of each supporting rod is installed on the hydraulic jack base. The supporting disc is provided with four counter bores and two groove-type through holes. The supporting disc is arranged at the ends, with the inner threads, of the supporting rods through the counter bores and the hexagon socket screws. Two protruding fixing ends are arranged at the lower end of each fixing screw rod. The fixing ends are installed in the groove-type through holes of the supporting disc. Outer threads are arranged at the upper portions of the fixing screw rods, and the fastening nuts are installed at the upper threads of the fixing screw rods. An experimental sample can be easily taken out through the mold opening device for the laboratory via the upward force of the hydraulic jack, and operation is easy.
Description
technical field [0001] The invention relates to the technical field of molds, in particular to a laboratory mold opener. Background technique [0002] Mold is known as the "mother of industry" and plays an important role in industrial production. Molds are also needed when doing various hot-press sintering and cold-press molding experiments in the laboratory, but after the experiment is completed, due to the sample bonding on the mold and the high internal pressure, the made samples and mats Chips are not easy to take out, especially metal molds are difficult to take out regardless of cold pressing or hot pressing sintering, which brings certain difficulties to the next experiment. Contents of the invention [0003] In order to solve the existing problems, the present invention proposes a laboratory mold opener, which can easily take out experimental samples and is simple to operate. [0004] In order to achieve the above object, the technical solution of the present inv...
