Vertical Parting Boxless Molding Machine Perfectly crafted for the mass production of small and medium-sized cast iron parts, including gray, malleable, and ductile iron, this machine epitomizes efficiency and quality. It boasts high production efficiency, unparalleled dimensional accuracy, and top-tier surface quality of castings. Its operation is quiet, and it enhances productivity with low labor intensity. The streamlined group line requires minimal auxiliary machinery, thus occupying a smaller footprint and demanding lower labor and construction investment. Additionally, it's energy-efficient and promotes a superior working environment.
Characteristics of the Molding Machine:
1. The electrical system is engineered with an imported Mitsubishi programmable controller (PLC), ensuring centralized automatic control of the main and auxiliary machines. Programming and adjustments are a breeze, thanks to the PLC's strong anti-interference capability and stable operation. The thoughtfully crafted program boasts a perfect self-locking protection function and fault detection, safeguarding every operation.
1. Machine Base: Constructed primarily of welded structural parts, the machine base acts as the steadfast foundation supporting all other components. With 14-foot screw holes, it anchors the machine securely to its foundation. Adjustable pads allow for precise horizontal alignment. Ingeniously designed holes beneath the front part and positive pressure plate cavity facilitate the efficient removal of sand, ensuring cleanliness and maintenance ease.
2. Cavity Frame: Comprising upper and lower frames, side frames, top, side, and bottom plates, guide pillars, back frames, and cross brackets, the cavity frame is a marvel of design. Screwed securely to the frame, the cavity's working surfaces are easily replaceable without disassembling the molding chamber frame, ensuring seamless operation and maintenance.
3. Positive Pressure Plate Mechanism: A harmonious assembly of plate body, heater, vibrator, and stroke position slide tube, this mechanism is pivotal for various processes. Connected to the front cylinder's piston, it expertly compacts, pushes, and closes molds while signaling position via sensors. Adjustable sliding pads ensure concentricity with the cylinder, offering precision and reliability in every operation.
4. Counter-pressure plate mechanism: The sophisticated counter-pressure plate mechanism is ingeniously designed with a robust plate body, a precise heating liner, a powerful heater, a dynamic vibrator, a sand blowing clean nozzle, a stable counter-pressure plate frame, a state-of-the-art four-link mechanism, and more. This marvel of engineering is seamlessly connected to the counter-pressure plate cylinder piston through four sturdy guide pillars and cross brackets, enabling smooth and efficient operations in both starting the mold and closing the cavity. A position sensor on the guide pillar sends accurate position signals of the counter-pressure plate, while horizontal adjustments of the counterpressure plate body ensure exceptional accuracy and alignment. The four adjusting pillars on the frame meticulously maintain the vertical position of the counterpressure plate with the bottom plate during sand shooting and mold starting.
5. Sand injection system: The cutting-edge sand injection system boasts a high-capacity gas storage tank, meticulously engineered sand injection cylinder, efficient sand gate mechanism, precision-controlled sand injection valve, quick discharge valve, and a reliable material level meter. The sand injection pressure is expertly managed by two advanced pressure reducing valves, with adjustments finely tuned between 0.3MP to 0.4MP. Electrical controls offer precision in adjusting the sand injection valve's opening time, while the sand injection cylinder is designed to accommodate 1.5 times the sand type, ensuring optimal performance. When the sand reaches maximum capacity, a level meter signals the sand adding machine to halt and closes the sand gate, maintaining seamless operation.
6. Oil cylinder: Ingeniously aligned along the coaxial line, the system features a front cylinder driving the positive platen and a rear cylinder controlling the reverse platen. Utilizing a combined cylinder design, the system allows for swift piston movements. Except during the compaction process, the working oil circuit directs pressure oil into the small area oil cavity, ensuring rapid piston action and enhancing overall machine efficiency.
7. Hydraulic system principle description
The hydraulic system components proudly boast standardization and efficiency. The system is divided into two essential parts: the control oil circuit and the working oil circuit. A duplex vane pump fuels the control oil circuit, with the first-level pressure oil ingeniously controlling the oil pump's swing angle, allowing the cylinder piston to achieve precise variable speed movements to meet operational requirements. Users can set compaction pressure adjustments between 7-9MP, while the combined force value is tailored to 4-5MP. The pressure sensor masterfully controls the machine's compaction ratio pressure size, and adjusting to a higher pressure value will enhance compaction ratio pressure. Notably, any changes in the pressure sensor value necessitate corresponding adjustments in the three-stage overflow. To ensure stable operation, a tubular heater, cooler, and oil temperature measuring sensor, along with its control oil circuit, form the oil temperature control link, maintaining temperatures between 35-45 degrees.
8. Electrical system principle description
The advanced electrical system adopts an AC 380V power supply (requiring a three-phase five-wire system) complemented by a control circuit using AC 220V power. The machinery offers versatile operational modes, including manual, single-action, full-line linkage, and a manual down core function. User-friendly interface features start, stop, emergency stop buttons, and more. The main machine's process flow is thoughtfully designed as cavity closing - sand shooting - compaction - mold starting 1 - pushing out the mold closing - mold starting 2. In emergencies, the system allows mid-process stops with the emergency stop disconnecting the control part's power and the middle stop cutting off the solenoid valve output. Resuming operations is seamless from the exact stop location, with the stop button initiating a full cycle to the initial position, ensuring safety and efficiency.
