Description

Technical Field

[0002] The molding machine is a casting equipment used to make sand molds. Its main functions are: filling sand, filling loose molding sand into the sand box; compacting the molding sand, compacting the loose molding sand in the sand box through different methods such as vibration, compaction, vibration pressure, and shooting pressure, so that the sand mold has the necessary strength during transportation and pouring; demolding, using different mechanisms to remove the pattern from the compacted sand mold. In batch and mass production, machines are often used to make cores. At this time, in addition to the sand compaction methods such as vibration and compaction, the most commonly used is the core shooting machine. The core shooting technology has developed with the changes in core sand binders and core making methods. The core shooting machine, also known as the injection molding machine, uses compressed air to evenly inject the molding sand into the sand box for pre-compaction, and then applies pressure for compaction. Commonly used are vertical parting boxless injection molding machines and horizontal parting boxless injection molding machines.
