Semi-auto Heat Core Box Blowing Machine

Application direction: plumbing, hardware, pump valves, fire fighting, automobile and motorcycle accessories and other industries.
Analysis of output products: manufacturing of various sand cores for small and medium-sized workpieces in the valve, faucet, hardware, hydraulic and pneumatic industries.
Process composition: 1. Sand adding: The sand shooting cylinder moves below the sand cylinder, and the sand closing mechanism opens to start receiving sand. After receiving the sand, the sand shut-off mechanism is closed, and the sand shooting cylinder moves to the top of the mold;
2. Mold clamping: the movable mold assembly moves to coincide with the static mold assembly, and the core pulls up;
3. Sand shooting: the sand injection cylinder under the shooting head is close to the mold, the sand shooting valve is opened, and the sand shooting starts;
4. Heating and curing: the shooting head moves up, the sand shooting cylinder moves up, and it is heated and solidified;
5. Opening the mold: move the core down, move the movable mold parts back, automatically eject the core, and manually take out the sand core;
6. Sand adding: There is a preset counter, after the number of shots is reached, the sand will be automatically added to the shot barrel; the core pulling can be turned off.

The hot core box core shooting machine is a hot core box core shooting machine that integrates mechanical and pneumatic. It is mainly composed of 7 subsystems: frame, mold clamping, sand leakage, core pulling, air control, electric control, and machine identification. 

1. The frame is welded with high-quality carbon structural steel, and the stress is eliminated after welding and integrated processing to ensure the rigidity and processing accuracy of the frame; it is the skeleton that supports each subsystem of the core shooter;

2. The contactor and relay adopt Schneider, and the switching power supply adopts Taiwan Mingwei, a professional brand, with stable performance;

3. The air control system is composed of rack air cylinders, cylinders, pipelines and related air circuit control components. The main supporting pneumatic components are all Taiwanese Airtac brand products, first-line brand high-end configuration, fast response, and improved equipment life;

4. Customers need to prepare their own refrigerators to keep the water temperature at about 10°;

5. A gate valve and an oil-water separator must be installed between the main air pipe of the machine and the main air pipe of the workshop to remove the water contained in the compressed air.

1. The man-machine interface and imported high-quality electric control and pneumatic components ensure accurate and reliable control and easy operation;

2. Sand filling and compaction are completed at the same time, the core sand hardens fast, and a cycle period only takes ten to tens of seconds;

3. It can shoot complex sand cores, with good quality, precise size and smooth surface, which can effectively control the machining allowance of castings;

4. The sand-shooting cylinder can be moved, and it is convenient to manually clean the sand-shooting hole when away from the high-temperature area; it can shoot dry sand or wet sand, which can save a lot of auxiliary equipment and tools for core making, such as core drying furnace, dryer, Core bone, wax thread, etc.;

5. The mold clamping base can be moved along the X axis, which makes the sand hole of the perforation alignment mold more convenient and accurate.

6. Using pneumatic device and electric heating, the temperature can be automatically controlled, and the work site is easy to keep clean, creating good conditions for the mechanization of core making.
