Vertical Parting Boxless Molding Machine Perfectly engineered for the mass production of small and medium-sized cast iron components—be it gray, malleable, or ductile iron. This machine stands out with its remarkable production efficiency, precise dimensional accuracy, and superior casting surface quality. It operates at a whisper, ensuring low noise levels and reduced labor demands. Thanks to a streamlined group line and minimal auxiliary machinery footprint, it offers both energy savings and an optimal working environment while minimizing labor and construction investments.
Characteristics of Molding Machine:
1. The advanced electrical system integrates a Mitsubishi PLC, renowned for its reliability, to centralize automatic control of both primary and auxiliary machines. Programming and adjustments are a breeze with its user-friendly interface, delivering robust anti-interference capabilities, steady operations, and a meticulously crafted self-locking protection and fault detection program.
1. Machine base: Expertly crafted from welded structural parts, the machine base serves as the foundation's backbone. It’s anchored via 14-foot screw holes and fine-tuned to a perfect horizontal position with adjustable pads. Ingeniously designed sand accommodation holes capture escaping sand, with removable covers for effortless cleaning, ensuring seamless operation.
2. Cavity Frame: An assembly masterpiece, comprising upper and lower frames, side frames, top and bottom plates, and more. Connected via screws, the working surfaces are easy to replace without disassembly, ensuring seamless operation and maintenance.
3. Positive Pressure Plate Mechanism: A marvel of engineering, featuring a plate body, heater, vibrator, and slide tube. Attached to the front cylinder’s piston, it orchestrates compaction, mold starting, and other actions with precision. Adjustable sliding pads guarantee perfect piston-cylinder alignment, underscoring the machine’s commitment to excellence.
4. Counter-pressure plate mechanism: This essential component is a masterpiece of engineering, comprising the plate body, heating liner, heater, vibrator, sand blowing clean nozzle, counter-pressure plate frame, and a sophisticated four-link mechanism. These elements harmoniously connect to the counter-pressure plate cylinder piston through four guide pillars and cross brackets, seamlessly moving with the piston to expertly execute the actions of mold starting and cavity closing through two precision processes. The counter-pressure plate's position is communicated via a position sensor on the guide pillar, allowing meticulous horizontal adjustments to enhance the overall machine's accuracy. With the assistance of four adjusting pillars on the counterpressure plate frame, it ensures perfect vertical alignment with the bottom plate during the sand shooting and mold starting phases, epitomizing precision and reliability.
5. Sand injection system: This system is a carefully orchestrated ensemble of a gas storage tank, sand injection cylinder, sand gate mechanism, sand injection valve, quick discharge valve, and material level meter, each playing a vital role. The system's sand injection pressure, finely tuned through two expertly calibrated pressure reducing valves, typically ranges from 0.3MP to 0.4MP, ensuring optimal performance. The sand injection valve's opening time, adjustable through precise electrical control, allows the sand injection cylinder to hold approximately 1.5 times the volume of a sand type. Once the sand reaches its full capacity, the level meter alerts the sand adding machine to halt sand addition and close the sand gate, ensuring seamless operation and avoiding any overflow.
6. Oil cylinder: Ingeniously designed, the oil cylinder features a front cylinder (driving the positive platen movement) and a rear cylinder (driving the reverse platen movement), both strategically aligned along the coaxial line. This innovative design, adopting a combined cylinder form, ensures that except for the compaction process, during all other cylinder actions, the pressure oil from the working oil circuit enters the small area oil cavity, facilitating the piston's rapid and efficient movement.
7. Hydraulic system principle description
The hydraulic system, built upon standard components, is a marvel of modern engineering. Divided into two main parts, the control oil circuit and the working oil circuit, it is powered by a duplex vane pump. The first-level pressure oil controls the oil pump's swing angle, enabling the cylinder piston to perform a variable speed movement tailored to the machine's operational demands. Users can adjust the compaction pressure to their desired level (7-9MP recommended), and the combined type force value can be set to 4-5MP. A pressure sensor manages the compaction ratio pressure size, and when the pressure value is altered, the three-stage overflow must be adjusted accordingly. The system's temperature stability, maintained between 35-45 degrees, is ensured by the tubular heater, cooler, and oil temperature measuring sensor, integrated into the oil temperature control link, promising stable and uninterrupted hydraulic system performance.
8. Electrical system principle description
The electrical system, powered by a robust AC 380V supply (with a three-phase five-wire system), and an AC 220V control circuit, empowers the entire machine with manual, single-action, full-line linkage, and a manual down core function. Equipped with start, stop, emergency stop buttons, the main machine follows a meticulous process flow: cavity closing, sand shooting, compaction, mold starting 1, pushing out mold closing, mold starting 2. In scenarios requiring immediate cessation, the system can be halted mid-operation, with an emergency stop disconnecting the control power supply, and a middle stop severing the solenoid valve output. Upon restart, the machine resumes from the stopped point, ensuring continuity. When the stop button is engaged, the machine cycles back to the initial position, ready for the next command.
