[0002] Core making machines convert powdered raw materials into finished products by rotating and pressing them into shape. The main working principle of a core making machine is to compress and shape raw materials such as metal powder or alloys using rotation and pressure. Usually, a support rod or template will maintain the shape of the part during the operation of the core making machine. During the process, the rotating shaft will evenly distribute the powder or alloy material to various parts of the part, and then press and form the part to solidify the shape. This method can make the part have higher strength and durability, while also reducing the scrap rate in the production process.

[0003] The process flow of the existing core making machine is to clamp the mold through the cylinder, extend the feeding hopper cylinder to the mold mouth to add resin sand, wait for the mold to be heated for a certain period of time, and after the resin sand is formed, the cylinder pulls open the mold, and the staff removes the finished sand core by hand. Due to the high temperature in the neutron core making process, equipment failure and personnel misoperation are very likely to occur during the sand core removal process, resulting in mechanical injury accidents.
