The invention relates to the technical field of detection of collapsibility of precoated sand. The invention discloses an efficient collapsibility detection device for precoated sand production. The detection device comprises a working box, and two through cavities are symmetrically formed in the right side surface of the working box; a first cover plate is hinged to the top of the working box; two second cover plates are symmetrically hinged to the top of the working box; two fixing plates are symmetrically and fixedly connected to the left inner wall and the right inner wall of the working box, two first motors are symmetrically and fixedly connected to the top of the working box, threaded rods are fixedly connected to the output ends of the two first motors, and the bottom ends of the two threaded rods penetrate through the top of the working box and are rotationally connected with the tops of the two fixing plates correspondingly. The precoated sand collapsibility detection devicesolves the problems that an existing precoated sand collapsibility detection device is generally low in detection efficiency and poor in detection result reliability.
Description
technical field [0001] The invention relates to the technical field of detection of the collapsibility of coated sand, in particular to an efficient detection device for the collapsibility of coated sand for production. Background technique [0002] Coated sand is mainly made of high-quality selected natural quartz sand, and is made of thermoplastic phenolic resin, urotropine and reinforcing agent. The shell formed by it can be used for steel castings, iron parts, etc., and the castings produced by it have high dimensional accuracy and good surface quality, so they are widely used in the field of casting. [0003] When the coated sand is used in the casting process, according to different casting requirements, it is necessary to adjust the ratio properly in terms of its curing speed, release property, fluidity, collapse property, casting surface finish, storage, etc., in order to obtain the optimal The collapsibility is an important parameter. If the collapsibility is good,...
