The core shooter is made of coated sand, which is suitable for hot core boxes and cold core boxes. The core shooting machine is characterized by the application of two guide pillars, the opening and closing of the mold are vertically divided, and two different sets of molds are installed at the same time. The fixed mold can be installed on both sides of the middle fixed frame, and the left and right opening and closing of the mold (equivalent to double mold bases). Core shooters are widely used in the casting industry. The cores manufactured by core shooters have accurate dimensions and smooth surfaces. 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 core will be preheated and hardened to a certain thickness (about 5-10mm) in the core box and taken out to form a high-quality core product with smooth surface and accurate size.
Routine maintenance
1. Check each cylinder, air circuit and valve for air leakage and eliminate it in time.
2. Clean the contact surfaces of moving parts at any time during work. Such as guide sleeve and guide post.
3. Regularly check whether the connecting fastening bolts and nuts of each component 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. The electric cabinet and operating surface shall be kept clean. Close and fasten the door after maintenance or setting time.
Personnel who have not been trained in core shooter operation shall not operate this equipment. It is necessary to idle manually before active work. Before starting, check whether there are guides in moving parts and whether there are non equipment operators approaching. Do not put things and other sundries on the equipment. Personnel who have not been trained in core shooter operation shall not operate this equipment. It is necessary to idle manually before active work. Before starting, check whether there are guides in moving parts and whether there are non equipment operators approaching. Do not put things and other sundries on the equipment. When the equipment is working, it is not allowed to touch the moving parts and electrical components. When the equipment in operation is suddenly suspended due to external power supply interruption, the power switch of the equipment shall be blocked to avoid the risk of re incoming power. During the maintenance, inspection, adjustment and cleaning of the core shooter. The main power supply and main compressed air valve shall be blocked. The solenoid valve may not recover to its original state after maintenance, inspection and adjustment. Pay attention to investigation after power on and ventilation to avoid risks caused by unexpected actions. In case of abnormal sound, smell and other abnormal phenomena in the operation of each part of the core shooter, the operation shall be stopped immediately. After checking and adjusting, it is necessary to conduct manual idling test run. After the core shooter works, it is necessary to stop at the original position and then cut off the power supply.
