Equipment for automatically manufacturing core mold

Abstract

The invention relates to the technical field of manufacturing of core molds, and discloses equipment for automatically manufacturing a core mold. The equipment comprises a fixing box; the bottom in the fixing box is conical; a driving motor is installed at the upper end outside the fixing box through a mounting mechanism; the output end of the driving motor is fixedly connected with a rotating rod; the rotating rod is arranged in a way of penetrating through the fixing box and is rotationally connected with the fixing box through a first bearing; the first bearing is located in the fixing box;the rotating rod is fixedly sleeved with a rotating cylinder; the upper end of the rotating cylinder is in a circular platform shape; the portion, corresponding to the rotating cylinder, of the interior of the fixing box is fixedly connected with a fixing sleeve; the opposite side walls of the fixing sleeve and the rotating cylinder are each fixedly connected with a plurality of crushing teeth; astirring mechanism is installed on the rod wall, close to the lower end, of the rotating rod; and the bottom of the fixed box fixedly communicates with a discharging cylinder. According to the equipment for automatically manufacturing the core mold, foundry sand can be preliminarily processed, so that caked or large particles in the foundry sand are smashed, and in this way subsequent machining is facilitated.

Description

technical field [0001] The invention relates to the technical field of mandrel manufacturing, in particular to equipment for automatically making mandrels. Background technique [0002] At present, most of the core molds used in the casting of pipe fittings in the foundry industry are made manually, which requires many people. The cost of coated sand for the core mold is expensive, and the processing cost of pipe fittings is too high. [0003] In the patent with the patent number CN206065346U, a kind of equipment for automatically making core molds is disclosed, and its technical scheme is composed of a frame device, a core mold forming device, a spraying device, and a trolley device; the core mold forming device and the described The frame device is connected with the fixed platform on the frame in the frame device through the upper mold box fixing plate in the core mold forming device, and the lower mold box fixing plate in the core mold forming device is connected with th...
