Description

Technical Field

[0001] This utility model relates to the field of lost foam drying technology, specifically a lost foam drying device. Background Technology

[0002] With the rapid development of my country's economy, the industrial level of the Chinese people is also constantly improving. Among molds, lost foam casting is now the most widely used. Lost foam casting is a type of casting using dry sand without binders combined with vacuum technology on foam plastic molds. Domestically, it is mainly called "dry sand casting" or "negative pressure casting," abbreviated as EPC casting; internationally, it is mainly called Lost Foam Process (USA) or Policarb Process (Italy). Lost foam casting is one of the most advanced casting processes internationally, and a lost foam drying device is used after the process.

[0003] However, most current lost foam drying devices use individual drying and cannot perform continuous drying, which reduces the drying efficiency of the device. In addition, most of the drying devices cannot be opened for maintenance, which reduces the practicality of the device. Utility Model Content
