Automatic Horizontal Flakless Molding Machine For Auto Parts

Vertical sand shooting solves the problem that the hardness of sand mold is inconsistent due to uneven sand shooting in the past molding machine, and can also reduce the collapse box and improve the dimensional accuracy of castings. The SMC air valve for sand shooting.The molding machine uses air flow to add sand, improves the quality of sand filling, ensures that the upper and lower sand boxes have no dead angle, effectively reduces the bad sand hole, improves the dimensional accuracy of castings, and can adapt to various characteristics of molding sand.

The molding machine adopts the principle of the whole process guidance of the four columns, and the upper and lower fixed seats and the four columns form a stable guidance system. The upper box slide frame, the lower box slide frame and the bottom slide frame are all positioned and guided through the four columns. It ensures the smooth and smooth completion of the box, sand shooting, compaction and release. Avoid the upper and lower box when the box with the pressure head body stuck, sand scraping edge and fragile phenomenon. At the same time, the tank positioning cylinder from the original four to two, not only guide to become stable, but also reduce the cost of equipment.

The stroke of the upper and lower compaction cylinder is 200 mm,250mm, respectively, and the position of the upper and lower compaction plate can be adjusted to produce different casting height. Suitable for casting with different thickness and thickness, saving sand for users.

The molding machine does not need professional workers, each complete molding only need to press the start button (not under the core setting condition), if there is needing core of the workpiece, program selection, automatically stop, after the completion of the core, press the mould closing button, the program is completed automatically. It saves a lot of manpower and material resources, and reduces the skill requirement of the operator. For the convenience of the core setting, some equipment adopt the turntable structure, so that the core setting is more convenient.

Six screws fixed, replaced within 5 minutes, adapted to frequent mould changes.

Mold hardness can be freely adjusted according to the requirements of different castings, only a few parameters need to be adjusted, very rapid and convenient, hardness can reach 85-90.

Each box is about 42seconds (excluding the core setting). Automatic release agent spraying system, automatic baking function.

The hydraulic system is composed of hydraulic station of Yuken ,6 hydraulic cylinders, full power; adopts Yuken control valve to realize the fast and slow operation of the cylinder, more stable and durable, save electricity and save energy; install the oil cooler system, make the hydraulic station can run stably for a long time; install the energy storage device, greatly improve the running speed. The permanent magnet magnetic block is installed at the bottom of the tank to ensure the cleanliness of the hydraulic system, the oil filter is installed to make the oil flow more smooth, and the hydraulic synchronous controller is installed to ensure the synchronization of the mould lifting.

PLC adopt OMRON brand, touch screen Mitsubishi panel, full automation control, graphical interface, human-computer interaction is convenient. With fault display, alarm function. The light screen system is installed to ensure the safety of the operator. Automatic lubrication system ensures the reliability of the equipment.

1), With manual, automatic control function, interlocking, self-locking function.

2),PLC use Japanese OMRON products, the main electrical components using Schneider products.

3),PLC reserve points for input and output.
