1results about How to "Improve core making efficiency" patented technology

The present application relates to the technical field of metal casting, and particularly discloses a core making machine, which is provided with at least two regulating systems in the circumferential direction of the side wall of a core box. During sand shooting, the exhaust adjusting branch of the regulating system controls the exhaust amount during sand shooting to avoid excessive pressure drop loss, and the negative pressure adjusting branch adjusts the vacuum degree in the cavity to increase the pressure difference between the region and other regions, improve the flowability of the sand, and facilitate compacting of the sand, thereby achieving good core making effect. During solidification and blowing, the blowing mechanism can blow triethylamine gas into the cavity through the top and side of the core box, achieve the best solidification and air intake combination, increase the air intake area, shorten the solidification time, improve the solidification efficiency, and increase the opening of the exhaust adjusting branch to increase the exhaust amount of the corresponding region and ensure smooth air intake. The present application also provides a sand shooting and solidification process control method applied to the core making machine.
