The vertical parting boxless molding machine is composed of a body, a mold ejection mechanism, a shock compaction mechanism, a rotary arm indenter, and a pneumatic piping system.
1. The fuselage is a solid hollow frame work piece. The upper part supports the indenter part of the rotating arm. When pressing, the rotating arm hooks the fuselage so that the pressing force is absorbed by the fuselage. In the indenter part, the indenter is fixed on a rocker arm that can rotate, and the indenter has a screw lifter that can be adjusted to the distance from the indenter to the sand box according to the height of the sand box
2. The swing arm controls the reciprocating movement of the cylinder piston through a hand-pulled valve to realize the movement of the positive arm and the swing arm.
3. The ejection structure consists of two ejection cylinders, connecting rods, balance shafts, ejection tables, ejection rods, etc. When the ejection cylinders are activated, the connecting rods, balance shafts, and ejection tables are driven to eject the four ejector rods at the same time. Moulding from the sand box.
4. Shock compaction structure. Adopt spring micro-vibration pneumatic compaction structure, compaction shock increases vibration. The clamping cylinder locks the vibrating cylinder when the mold is drawn, and the clamping cylinder is released when the mold is dropped.
5. Pneumatic piping system: the input compressed air is removed by air filter to remove water and impurities in the compressed air, and then lubricating oil is injected through the lubricator to supply various pneumatic components and mechanisms. The action of the machine is realized by the hand valve console .
6. Air supply and lubrication. The machine is realized by air source as energy and oil as lubrication. The intake pressure and oil volume are respectively adjusted by the pressure reducing valve and the oil regulating valve. When the air source passes through the lubricator, the oil is sucked into the pipeline according to the siphon principle, and the mist enters the pipeline system for lubrication.
Vertical parting boxless molding machine, used to make sand molds, is a professional production of pedestrian cover casting molding. The main functions of the molding machine are: filling, filling loose molding sand into the sand box; compacting the molding sand. Molding machines are widely used in industrial production. How to safely operate the molding machine is a concern of every producer. Sanzhuji combines the product characteristics and production experience of the vertical parting five-box molding machine to summarize. The following is the safe operation procedure of the molding machine .
Molding machine operating procedures:
1. Comply with the general operating procedures of molding machine and core making machine.
2. The ejector rod must be steadily and synchronously when the molding machine is drawn out. Otherwise, notify the maintenance personnel for repair.
3. When the molding machine is pressed in real time, the turret of the sand-pressing beam should rotate steadily, and do not operate too hard to cause shock.
4. The operator must pay attention to whether the mold is good before and after production, and whether the positioning pins of the outer mold and the core mold are matched.
5. The staff who operate the molding machine should concentrate their thoughts.
6. After the molding machine is completed, the mold should be hoisted to the specified pouring point (line) according to the process regulations. Place them neatly and lock the box with iron or clip. Miscellaneous items must be marked.
7. The sand box of the molding machine is not allowed to be stacked too high, generally not more than two meters, and the tools used must be stacked neatly to prevent accidents.
8. Pay attention to safety when using blowtorch to prevent fire. The running lights must be low-voltage bulbs below 36V, and high-voltage bulbs above 220V are prohibited.
9. When the molding machine is used for driving, check whether the spreader is in good condition. When lifting, the hook should be fastened and the chain should be straightened. Oblique lifting and overload lifting are not allowed.
10. It is strictly forbidden to repair the mold under the lifting sand box. Unpacking the large sand box, when turning over the box, it must be filled with square objects.
11. The sand box used by the molding machine must be firm, and the hand must be intact without cracks and bending.
