Green Sand Vertical Molding Machine

In recent years, with the improvement of the economic level and the increase of labor costs, the foundry industry has updated the equipment. On the one hand, the manual operation is low efficiency, there are errors, affecting the quality of castings; on the other hand, the temperature of the casting workshop is high, the operating environment is relatively poor; coupled with automated assembly line casting has become the trend, so in the molding sand casting equipment fully automatic equipment gradually replace the original semi-automatic equipment or manual work, the following is mainly to introduce the classification and use of molding machine.
Sand casting in most cases there will be mold, mold is the carrier of the casting, sand is the swaddling clothes of the casting mold, the tightness of the sand is the prerequisite for the quality of the casting, the current sand production is divided into two kinds, the first is a semi-automatic compaction molding machine, mainly by hand to add sand, and then compacted by equipment, manual mold, efficiency is relatively low, mainly depending on the physical strength of the operator about 25-30 boxes per hour The other type is the injection molding machine, which is mainly divided into vertical parting boxless injection molding machine and horizontal parting boxless injection molding machine. The sand is directly injected into the moulding chamber with a template, which has high dimensional accuracy and high productivity because there are cavities on both sides of the sand box. The horizontal splitting off-box injection molding machine uses the sand box for molding, and it is convenient to take off the core after the sand model is made, and the productivity is high.
The main functions of the vertical split-boxless injection molding machine (hereinafter referred to as automatic vertical molding machine) are: automatic sand filling, filling the regenerated sand into the sand box; compacting the sand, compacting the loose sand in the sand box by injection, compaction, mold starting and other processes, so that the sand has the necessary strength in the process of handling and pouring, to ensure the quality of the casting, the automatic vertical molding machine produced by three casters, sand mold molding The automatic vertical molding machine produced by three casters has the capacity of 200-220 boxes per hour, the whole equipment adopts PLC centralized automatic control, high operation efficiency and good sand compactness, which is well received by the foundry industry.

1、Automatic vertical molding machine is composed of machine body, rotating arm, mould starting structure, shock compaction mechanism, rotating arm pressure head part and pneumatic piping system, etc., which can be designed and manufactured according to customer''''''''''''''''s casting condition.
1.1 The machine body is made of a solid hollow frame workpiece, the upper part of which supports the press head part of the rotating arm, and when compacting, the rotating arm hooks the machine body so that the compacting force is borne by the machine body, and the machine body is connected to the shock mechanism with bolts, and the press head part of the rotating arm is fixed on the swinging arm, and the press head has a screw lift to adjust the distance from the press head to the sand box according to the height of the sand box.
1.2 The rotating arm is controlled by a hand-pull valve to control the piston of the cylinder to move back and forth to realize the positive arm and rotating arm movement.
1.3 Mould starting structure consists of two mould starting cylinders, connecting rod, balancing shaft, mould starting table, mould starting rod, etc. When the mould starting cylinder starts, it drives the connecting rod, balancing shaft and mould starting table to make the four top rods lift the sand box and start the mould at the same time.
1.4 Shock compaction structure. Adopt spring micro-vibration pneumatic compaction structure, compaction shock to increase the vibration. The clamping cylinder locks the compaction cylinder when the mold is started, and the clamping cylinder is released when the mold is dropped.
1.5 Pneumatic piping system: the input compressed air, through the air filter to remove the water and impurities in the compressed air, and then through the oil mist injected lubricant, supply each pneumatic components and institutions, the machine action by the hand-pull valve console to achieve.
1.6 air supply and lubrication. The machine is by the air source for energy and oil to do lubrication to achieve the work. The size of the inlet pressure and the size of the oil volume are regulated by the pressure reducing valve and oil regulating valve respectively. Air source through the oil fogger according to the principle of siphon will be oil into the pipeline, fog into the pipeline system for lubrication.

2、how to safely operate the molding machine is the concern of each foundry, three casting machine combined with more than a decade of manufacturing experience and production experience summed up the following operating procedures
2.1 comply with the molding machine and core making machine general operating procedures.
2.2 When the moulding machine starts, the top bar must be smooth and synchronous on or, otherwise, notify the maintenance personnel to repair.
2.3 molding machine compaction, pressing sand beam rotating frame should be smoothly rotating, do not operate too hard, produce impact.
2.4 The operator must pay attention to whether the mold is good before and after production, the outer mold and the core mold positioning pin is matching.
2.5 The staff operating the molding machine should be concentrated.
2.6 After the completion of the molding machine box, according to the provisions of the process, the mold should be lifted and moved to the developed pouring point (line). Place neatly, and press iron or card lock box. Miscellaneous parts must indicate the mark.
2.7 molding machine sand box is not allowed to stack too high, generally not more than two meters, the tools used must be stacked neatly to prevent accidents.
2.8 the use of blowtorch should pay attention to safety, to prevent fires, the use of line lights must be 36V low-voltage bulbs below, banned 220V high-voltage bulbs.
2.9 molding machine using the crane should first check whether the spreader is good, lifting hooks should be tied chain straight, not allowed to slant lifting and overload lifting.
2.10 strictly prohibited in the lifting sand box below the repair operation. Large sand box open box, turn over the mat box must use square objects to pad properly.
2.11 sand box used in the molding machine must be solid, the hitch should be intact without cracks and bending phenomenon
