Vertical Parting Boxless Molding Machine Designed for the mass production of small to medium cast iron parts—including gray, malleable, and ductile iron—this machine stands out with its high production efficiency, remarkable dimensional precision, and exceptional casting surface quality. Enjoy a quieter, energy-efficient environment with reduced labor intensity and minimal auxiliary machinery, all while benefiting from a compact setup that cuts down on labor and construction investment.
Key Characteristics of the Molding Machine:
1. Our electrical system incorporates the top-tier Mitsubishi programmable controller (PLC) for centralized automatic control of both main and auxiliary machines. Revel in the convenience of easy PLC programming and adjustment, while benefiting from its strong anti-interference ability and stable performance. The system's well-thought-out program includes a perfect self-locking protection feature and fault detection capability.
1. Machine Base: A cornerstone of strength, the machine base consists of welded structural parts that support the other components. With 14 secure screw holes, it firmly anchors the machine to its foundation. Its design includes a clever mechanism to handle any sand leakage, allowing for easy cleaning through removable cover plates.
2. Cavity Frame: This frame is intricately designed with upper and lower frames, side frames, top and bottom plates, guide pillars, and a back frame with a supporting cylinder. Screws connect the cavity’s working surfaces to the frame, enabling easy replacement without dismantling the molding chamber frame.
3. Positive Pressure Plate Mechanism: Featuring a plate body, heater, vibrator, stroke position slide tube, and more, this mechanism is linked to the front cylinder piston. It handles compaction, pushing, closing, and other processes, with positional signaling provided by a position sensor. Adjustable sliding pads ensure height precision and piston-cylinder alignment.
4. Counter-pressure plate mechanism: This vital component is an intricate assembly that includes a plate body, heating liner, heater, vibrator, sand blowing clean nozzle, and a counter-pressure plate frame, linked together by a sophisticated four-link mechanism. It operates in harmony with the counter-pressure plate cylinder piston through four guide pillars and cross brackets, facilitating the seamless initiation of mold 1 and ensuring precision in cavity closure. The position sensor on the guide pillar transmits the counterpressure plate's position signal, while horizontal adjustments fine-tune the machine's overall accuracy. The four strategically placed adjusting pillars on the frame ensure the counterpressure plate's perfect vertical alignment with the bottom plate during sand shooting and mold initiation.
5. Sand injection system: This system is thoughtfully engineered with components such as a gas storage tank, sand injection cylinder, sand gate mechanism, sand injection valve, quick discharge valve, and a material level meter to ensure consistent performance. The system's gas tank sand injection pressure is expertly managed by dual pressure-reducing valves set between 0.3MP-0.4MP. The sand injection valve's timing is finely adjustable via electrical controls, typically allowing the sand injection cylinder to hold up to 1.5 times the sand necessary for a single type. A level meter signals when the sand reaches full capacity, prompting the sand adding machine to cease operation and securely close the sand gate, maintaining optimal efficiency.
6. Oil cylinder: Designed for peak performance, the system features both a front cylinder, driving positive platen movement, and a rear cylinder, handling reverse platen movement, both positioned along a coaxial line. This dual-cylinder setup employs a combined cylinder form, which, outside the compaction process, optimizes piston speed by channeling pressure oil only into the small area oil cavity—facilitating rapid piston movement and enhancing overall operational efficiency.
7. Hydraulic system principle description
The hydraulic system is built on reliable standard components. It distinguishes between two distinct circuits: the control oil circuit and the working oil circuit. The duplex vane pump powers the control circuit, with the primary pressure oil adjusting the swing angle of the oil pump, enabling precise variable-speed piston movements to meet operational demands. User-defined compaction pressure values range from 7-9MP, with combined-type force adjustments at 4-5MP. A pressure sensor meticulously controls the compaction ratio, allowing for adjustments that elevate compaction pressure. Changes in the pressure sensor's settings necessitate corresponding modifications in the three-stage overflow. A comprehensive system of a tubular heater, cooler, and oil temperature sensor, along with its control oil circuit, maintains oil temperature between an optimal 35-45 degrees, ensuring the hydraulic system's stable and efficient operation.
8. Electrical system principle description
The electrical system ingeniously utilizes an AC 380V power supply within a three-phase five-wire configuration, while the control circuit operates on AC 220V. This system offers versatile functionality with manual, single-action, full-line linkage, and manual down core options, featuring essential start and stop controls, including an emergency stop button. The main machine's process flow consists of cavity closing, sand shooting, compaction, mold initiation 1, mold ejection, followed by mold closing and mold initiation 2. In emergencies, the system can be halted instantly, with an emergency stop cutting control power and a middle stop halting the solenoid valve output, ensuring safe and precise operation. Resuming operation from a stop point is seamless, as the system cycles back to its initial position upon pressing the stop button, ready for efficient continuation.
