Description

Technical Field

[0001] The utility model relates to the technical field of core making machines, in particular to an automatic feeding core making machine for precision casting engineering. Background Art

[0002] The core making machine is a general term for the core shooting machine and the shell core machine. It is a device that uses the hot core box process to make coated sand shell cores. Its working process is to fill sand and compact it at the same time, and harden it immediately in the hot core box, which reduces labor intensity, is flexible and easy to operate, and is easy to master. It uses electric heating, the temperature can be automatically controlled, and the work place is easy to keep clean, creating conditions for the mechanization and automation of the core making process. A cycle takes only a dozen seconds to dozens of seconds to produce sand cores for casting. The cores made by the core shooting machine are accurate in size and smooth in surface. Widely used in the casting machinery industry, the shell core machine adopts the hot core box process, and the opening and closing molds are vertically parted. The whole machine structure is mainly composed of column components, sand shooting devices, mold frame components and other parts. The entire mold frame is installed on the base with left and right bracket plates. The movable mold plate moves left and right along the guide column under the push and pull of the mold closing to complete the core making process of mold closing and opening. When the movable mold plate is opened, the sand core automatically follows the movable mold plate under the action of the spring top force on the fixed mold plate, and can be easily removed manually. The turning device is driven by the cylinder to push and pull the rack to drive the gear on the bracket plate so that it can automatically turn over within a range of 180 degrees. The excess sand core that has not solidified inside is poured out to form the required shell core, but the current core making machine does not have an automatic feeding function, which requires manual feeding, which is very troublesome, and does not have a material screening function, resulting in more impurities in the material, affecting the use. For this reason, we propose a core making machine with automatic feeding for precision casting engineering. Utility Model Content
