Description

Technical Field

[0001] The invention relates to the technical field of core shooting machines, in particular to a multifunctional dual-purpose horizontal core shooting machine. Background Art

[0002] The core shooter is a shot-press molding machine that uses compressed air to evenly shoot the molding sand into the sand box for pre-compaction, and then applies pressure for compaction. Commonly used ones are vertical parting boxless shot-press molding machine and horizontal parting boxless shot-press molding machine. The vertical parting boxless shot-press molding machine does not use a sand box for molding. The molding sand is directly shot into the molding chamber with a template. The sand mold has high dimensional accuracy, there are cavities on both sides of the sand box, and the productivity is high, but it is difficult to set the core, and the quality of the molding sand is strict. The horizontal parting boxless shot-press molding machine uses a sand box for molding. After the sand mold is made, the mold is closed and the box is removed. It is convenient to set the core and has high productivity. When the horizontal core shooter on the market is in use, the unstable connection caused by the installation of the lower mold will directly affect the stability of the later shot-press molding operation. In addition, during the sandblasting process, some sand is shot out, which will cause certain direct pollution to the interior of the entire core shooter and its surrounding environment.
