  What kind of equipment is "core shooter"? In fact, it is the machine that the compressed air suddenly expands and injects the core sand into the core box. It uses compressed air to evenly inject molding sand into sand box for pre compaction, and then applies pressure for compaction. Core shooter it is commonly used in vertical type non box core shooter and horizontal type off box core shooter.
Next, lets talk about the working principle of the core shooter
   core shooter is made of coated sand, suitable for hot box. The core shooter is characterized by the application of two guide pillars, vertical parting of opening and closing mould, and the installation of two different moulds at the same time. The middle fixed frame can be installed with fixed mould on both sides, and the left and right opening and closing mould (equivalent to double mould frame). The core shooter is widely used in the foundry industry. The core made by the core shooter has accurate size and smooth surface. The working principle of the core shooter is to inject the core sand mixture with liquid or solid thermosetting resin as the binder into the heated core box. The sand core is preheated in the core box and quickly hardened to a certain thickness (about 5-10 mm) to take it out to form a high-quality sand core product with smooth surface and accurate size.
   lets introduce the five problems that should be paid attention to in the daily maintenance of the core shooter
   1. Check each cylinder, gas path and valve for air leakage, and eliminate it in time.   
   2. Clean the contact surface of each moving part at any time during work. Such as guide sleeve and guide post.   
   3. Regularly check whether the connecting and fastening bolts and nuts of all parts are loose, and tighten them in time.   
   4. Clean the equipment after work every day and thoroughly clean the inside and outside once a week.   
   5. Keep the electric control box and operation surface clean. Close the door tightly after non maintenance or setting time.
