Description

Technical Field

[0001] The utility model belongs to the technical field of horizontal core shooting machines, in particular to a horizontal core shooting machine for a front bracket of a heavy-duty vehicle. Background Art

[0002] The core shooting machine uses compressed air to evenly shoot the molding sand into the sand box for pre-tightening, and then applies pressure for compaction. Commonly used ones are vertical parting boxless shooting and pressing molding machines and horizontal parting boxless shooting and pressing molding machines. The molding sand is generally made of raw sand for casting, molding sand binder, auxiliary materials and other molding materials mixed in a certain proportion. Since the molding sand is mixed with binder, some of the molding sand will stick to the inner wall of the sand storage equipment after long-term use, and even clumps will form, which will gradually accumulate until the discharge port is blocked, affecting the normal operation of the core shooting machine.
