Description

Technical Field

[0001] This utility model relates to the field of automatic molding machine technology, specifically an automatic molding machine with protective function. Background Technology

[0002] An automatic molding machine is a piece of equipment used in the foundry industry. It can automatically complete the sand mold manufacturing process, including sand filling and compaction. Through an automated control system, it has high work efficiency and can greatly shorten the molding cycle compared to traditional manual molding.

[0003] The main function of an automatic molding machine is to automatically fill molding sand into a sand box and compact it into a mold with a certain shape and dimensional accuracy through processes such as compaction and vibration. It can complete the molding process efficiently and accurately, greatly improve production efficiency, reduce manual labor intensity, and ensure the stability and consistency of mold quality.

[0004] Existing automatic molding machines still have the following problems: they lack protective functions and cannot clean the interior. Usually, some debris will remain inside when making sand molds. Due to the lack of protective functions, this poses a safety hazard. Moreover, it is inconvenient to clean the interior, which reduces the service life of the internal parts. In order to address the above problems, an automatic molding machine with protective functions is proposed. Utility Model Content
