Description

Technical Field

[0002] A molding machine is a casting equipment used to make sand molds. Its main functions are to fill the sand, filling the loose molding sand into the sand box; to compact the molding sand, compacting the loose molding sand in the sand box through different methods such as vibration, compaction, vibration pressure, and shot pressure, so that the sand mold has the necessary strength during transportation and pouring; to demold, use different mechanisms to remove the mold from the compacted sand mold. The molding machine first appeared in the mid-19th century. The early molding machine was a simple manual compaction with a demolding mechanism. Later, compressed air was used as the power to vibrate and compact the molding sand. The commonly used is the micro-vibration compaction molding machine, which uses the falling workbench to collide with the floating vibrator, micro-vibrate and compact the molding sand, and then compact it.

[0003] When most molding machines are operating on molding sand, it is usually necessary to scrape the molding sand inside the molding machine so that the excess molding sand inside the molding machine can be scraped off, so that the molding sand can be made more compact later.
