Vertical Parting Boxless Molding Machine This cutting-edge machine excels in the mass production of small to medium-sized cast iron parts, including gray, malleable, and ductile iron. It stands out with its exceptional production efficiency, delivering high dimensional accuracy and superior surface quality for castings. The machine operates quietly and with minimal labor, featuring a straightforward assembly line. It requires less auxiliary machinery, optimizing spatial usage, labor, and construction investment. Embracing energy efficiency, it also offers a pristine working environment.
Characteristics of the Molding Machine:
1. The electrical system is enhanced by the renowned Mitsubishi programmable controller (PLC), providing centralized automatic control of both main and auxiliary machines. The PLC programming is intuitive and accessible, boasting a robust anti-interference capacity. The system operates seamlessly, fortified by an expertly crafted self-locking protection and fault detection function.
1. The machine base is the backbone of this innovation, constructed from sturdy welded structural parts. It securely supports other machine components and is anchored to the foundation using 14-foot screw holes, with precision leveling achieved through adjustable pads. The base features a strategically placed hole to collect and easily remove sand that escapes the plate slits.
2. Cavity frame: This robust assembly includes the upper and lower frames, side frame, top plate, side plate, bottom plate, guide pillar, and back frame, supported by a cross bracket and other assemblies. The working surface plates are screw-mounted onto the frame, enabling quick and easy replacements without the need to dismantle the entire molding chamber frame.
3. Positive pressure plate mechanism: At the heart of this system is the plate body, heater, vibrator, stroke position slide tube, and more. This mechanism works in tandem with the front cylinder piston, executing essential functions like compaction, pushing, and closing. A position sensor communicates the plate's position, while adjustable sliding pads ensure precise alignment and movement.
4. Counter-pressure Plate Mechanism: A marvel of engineering, this mechanism is a complex assembly consisting of a plate body, heating liner, heater, vibrator, and more, including a sand blowing clean nozzle. The counter-pressure plate is a masterpiece of precision, connected through four guide pillars and cross brackets to the cylinder piston. It seamlessly executes the starting and closing actions of the mold through two intricate processes. The position sensor on the guide pillar ensures precision by sending accurate position signals, allowing horizontal adjustments for machine accuracy. Adjustable pillars on the frame maintain the vertical alignment of the counter-pressure plate with the bottom plate, guaranteeing flawless sand shooting and mold initiation.
5. Sand Injection System: At the heart of this system is an array of components such as a gas storage tank, sand injection cylinder, and more, all working in harmony to deliver perfect sand injection. With pressure controlled by dual-reducing valves, the system operates at a finely tuned pressure range of 0.3 to 0.4 MPa. The electrical control governs the timing of the sand injection valve, while the sand injection cylinder holds 1.5 times the sand required for one type. A level meter ensures perfect timing, signaling the sand adding machine to halt when full, thereby closing the sand gate with precision.
6. Oil Cylinder: A showcase of innovation, the oil cylinder features both front and rear cylinders aligned coaxially, embodying the brilliance of combined cylinder design. During non-compaction phases, only the small area oil cavity receives pressure oil, facilitating swift piston movement, which is essential for the high-speed operation of the machine.
7. Hydraulic System Principle Description
The hydraulic system presents an array of standard components, divided into a control and working oil circuit. The duplex vane pump supplies the control oil, dictating the swing angle of the pump for desired piston movement speed. The compaction pressure, user-adjustable within 7-9 MPa, assures optimal machine performance, while the combined force value is set at 4-5 MPa. Pressure sensors regulate the compaction ratio, adjusting as needed to enhance performance. The system incorporates a tubular heater, cooler, and a temperature sensor, maintaining oil stability between 35-45 degrees for consistent hydraulic performance.
8. Electrical System Principle Description
The system's electrical backbone utilizes an AC 380V power supply alongside a 220V control circuit. Designed for versatility, it offers manual, single-action, full-line linkage, and manual core-down operation, complemented by start, stop, and emergency stop functions. The main machine's workflow—cavity closing, sand shooting, compaction, mold initiation, and ejection—ensures streamlined operation. In emergencies, the machine halts mid-cycle. Emergency stops cut power to the control segment, while mid-cycle stops cut solenoid valve output, ensuring the system resumes smoothly from the previous stopping point. Pressing stop cycles the entire line to a resting initial state.
