Equipment features1.Adopting PLC to control air pressure, shoot sand pressure can be adjusted.
2.The man-machine interface adjusts parameter and reveal movement state, it's simple, intuitive, convenient and precise.
3.The sand shooting tube deflects for adding sand so that we can keep far away from the high-temperature area which can prevent the sand insides the sand shooting tube from agglomerating. Besides, it is convenient for manually cleaning shooting hole.
4. The special oil-cylinder piston pole and non-oil lubricating bearing are adopted to this machine so that it has low friction drag and it is easy to replace accessories.
5.This machine is specially designed for valves, pipes and bathrooms by our company. This machine absorbs the advantage of similar types on structure from some excellent companies at home and abroad and combine with the production practice to improve its shortcomings continuously so that its function is improved, the efficiency is higher, the usage is more stable and mold replacement is more convenient. It can use not only resin sand(wet sand), but also coated sand(dry sand).
6.When the hot core box core shooter is working, sand insides the sand storage hopper goes into the sand shooting tube under the vibration of vibrating motor (when using coated sand, we can turn off the vibration motor); Under the action of air pressure, the loose form sand insides the sand shooting tube are densely and instantaneously shoot into mould cavity in a high speed, and the pressure is maintained for a short time. By the action of heat, sand insides the mould cavity gradually hardened. Open the mould after heating it for a period of time, then push out sand core from mould cavity via the core making machine, a eligible sand core is finished.
