Core shooting machine with optimized performance

Abstract

The invention relates to the field of casting, in particular to a core shooting machine with optimized performance. The core shooting machine comprises a machine frame, a template mechanism and a sand shooting mechanism, wherein the machine frame comprises a base; the base is fixedly connected with a top holder through a vertical plate; a sliding device is fixedly arranged on one side surface of the base; a sand adding hopper is fixed to the top holder; a sand adding cylinder is arranged on one side of the sand adding hopper; the sand adding cylinder is connected with an air bag; the template mechanism is arranged on the base; the template mechanism comprises templates; cylinders are fixed to the side surfaces of the templates; the cylinders run through the templates and are connected with movable templates; a first polished lever is fixed between one end edge of the first template and one end edge of the second template; a second polished lever is fixed between the other end edge of the first template and the other end edge of the second template; the sand shooting mechanism comprises a sand shooting barrel, a sand shooting hopper and a shooting plate; the sand shooting hopper is arranged at the lower part of the sand shooting barrel; a cantilever support is connected to the outer part of the sand shooting barrel; cantilevers are fixed to the two sides of the outer part of the cantilever support through bolts; a rotating shaft is mounted on one side of the bottom of the shooting plate; and a sealing device is fixedly mounted at the lower end of the rotating shaft. The core shooting machine is steady in operation and optimized in performance.

Description

technical field [0001] The invention relates to the field of casting, in particular to a performance-optimized core shooter. Background technique [0002] The core shooter uses compressed air to evenly inject molding sand into the sand box for pre-compaction, and then apply pressure for compaction. Commonly used are vertical type boxless injection molding machine and horizontal type out-of-box injection molding machine. [0003] CN201520275791.9 discloses a hot core box core shooting machine, including a sand adding mechanism, a sand shooting mechanism, a column, an upper support frame and an air storage bag. The beneficial effect achieved by it is: "the sand adding mechanism is provided with a spring, the spring It offsets most of the pressure acting on the rollers and guide rails during the whole process, ensuring the normal operation of the equipment and prolonging the service life of the equipment. The design of moving the left core box and fixing the right core box mak...

Problems solved by technology

"Existing core shooting machines, such as the above-mentioned application documents, only rely on the pressure effect on the inefficient roller guide rail of the spring is not obvious, and the stability of the mold clamping mechanism, especially the mold clamping mechanism that moves left and right, also needs to be stabilized due to long-term operation.
