Vertical Parting Boxless Molding Machine Crafted for mass production, the Vertical Parting Boxless Molding Machine excels in producing small to medium-sized cast iron components, including gray cast iron, malleable cast iron, and ductile iron. Witness the fusion of technological brilliance and production efficiency, delivering high dimensional accuracy and exquisite surface quality of castings. Experience reduced noise, minimal labor demands, and streamlined group line operations. Its compact design and minimal auxiliary machinery space requirements translate to low labor and construction investment, fostering energy savings and a pristine working environment!
Characteristics of the Molding Machine:
1. The electrical system is engineered for excellence, featuring the imported Mitsubishi programmable controller (PLC) for centralized, automatic control of both main and auxiliary machines. This PLC is heralded for its effortless programming and adjustment, robust anti-interference capability, stable operations, and a meticulously designed program complete with flawless self-locking protection and fault detection functionalities.
1. Machine Base: The robust foundation of this machine comprises welded structural parts that support all other components. It's secured to its foundation through 14-foot screw holes, and precision leveled using adjustable pads. A strategically positioned hole underneath the frontal section of the base and back cavity of the positive pressure plate captures displaced sand, which is then effortlessly removable by detaching the cover plates from the machine base's front sides.
2. Cavity Frame: This frame is an assembly of upper and lower frames, side frames, a top plate, side plate, bottom plate, guide pillar, back frame (supporting cylinder), cross bracket, and more. The working surfaces' top, bottom, and side plates attach to the frame with screws, allowing for easy replacement without disassembling the entire molding chamber frame.
3. Positive Pressure Plate Mechanism: This mechanism consists of a plate body, heater, vibrator, stroke position slide tube, and more. It connects with the front cylinder's piston, performing tasks like compaction, pushing, closing, and initiating mold 2 processes. A position sensor signals the positive pressure plate's position, while height-adjustable sliding pads ensure piston-cylinder concentricity during movement.
4. Counter-pressure Plate Mechanism: This sophisticated mechanism is primarily composed of a robust plate body, efficient heating liner, precise heater, dynamic vibrator, sand-blowing clean nozzle, sturdy counter-pressure plate frame, and an intricate four-link mechanism, among others. It's ingeniously connected to the counter-pressure plate cylinder piston via four guiding pillars and cross brackets. This ensures seamless movement with the piston, executing dual processes of starting mold 1 and closing the cavity. The position signal is deftly communicated through a position sensor on the guide pillar. For optimal machine accuracy, the counter-pressure plate body can be finely adjusted horizontally, thanks to the four adjusting pillars on its frame, ensuring perfect vertical alignment with the bottom plate during sand shooting and mold initiation.
5. Sand Injection System: Our cutting-edge system consists of an advanced gas storage tank, efficient sand injection cylinder, versatile sand gate mechanism, precision sand injection valve, quick discharge valve, and an accurate material level meter. Two pressure-reducing valves meticulously control the sand injection pressure of the gas tank, adjustable between 0.3MP to 0.4MP for optimal performance. Electrical control allows precise adjustment of the sand injection valve's opening time, ensuring the sand injection cylinder efficiently contains 1.5 times the required sand type. Once the maximum capacity is reached, the level meter signals the intelligent sand adding machine to cease operation and securely close the sand gate.
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, all arranged along a single coaxial line. This innovative combined cylinder design ensures that, outside the compaction process, the pressure oil of the working oil circuit enters only the small area oil cavity. This allows for the rapid movement of the piston, enhancing efficiency.
7. Hydraulic System Principle Description
The hydraulic system boasts a collection of standard components for unmatched reliability. It features a dual oil circuit: the control oil circuit and the working oil circuit. The control oil circuit is powered by a duplex vane pump, with the first-level pressure oil managing the swing angle of the pump itself, allowing the cylinder piston to achieve precise variable speed movements vital for the machine’s operational process. Users can adjust the compaction pressure to their desired level, recommending 7-9MP for optimal performance. The combined type force value can be set between 4-5MP. A pressure sensor meticulously regulates compaction ratio pressure, and any pressure value adjustments require corresponding fine-tuning of the three-stage overflow. Additionally, the tubular heater, cooler, and oil temperature measuring sensor, along with its control oil circuit, form an oil temperature control system, stabilizing oil temperature between 35-45 degrees to guarantee the hydraulic system’s consistent, smooth operation.
8. Electrical System Principle Description
The electrical system is ingeniously designed to utilize an AC 380V power supply via a sophisticated three-phase five-wire system, while the control circuit efficiently operates on AC 220V. The entire machine is equipped with multiple operation modes: manual, single-action, full-line linkage, and manual down core function, all complemented by intuitive start, stop, halt, and emergency stop buttons. The machine's seamless process flow includes cavity closing, sand shooting, compaction, mold starting 1, mold ejection, mold closing, and mold starting 2. In urgent situations, the system can halt midway through operations, with an emergency stop immediately cutting off the control part’s power, and a middle stop disengaging the solenoid valve output. When the machine restarts, it resumes from the precise point of interruption, ensuring a smooth cycle return to its initial position upon pressing the stop button.
