Vertical Parting Boxless Molding Machine This innovative machine excels in the mass production of small to medium-sized cast iron parts, including gray cast iron, malleable cast iron, and ductile iron. It boasts exceptional production efficiency, delivering castings with high dimensional accuracy and superior surface quality. The machine is engineered to operate quietly with low noise output and features a straightforward group line design that minimizes labor intensity. Its compact footprint reduces the need for auxiliary machinery and keeps construction investments low, all while promoting energy efficiency and a comfortable working environment.
Characteristics of the molding machine:
1. The electrical system is expertly crafted using a sophisticated Mitsubishi programmable controller (PLC), delivering centralized automatic control over both the main and auxiliary machines. This advanced PLC system offers convenient programming and adjustment, remarkable anti-interference capabilities, and stable operation. The thoughtfully designed program includes robust self-locking protection and fault detection functions, ensuring reliable performance.
1. Machine base: Serving as the foundation, the machine base is constructed from robust welded structural parts. It supports all other machine components and is securely fixed to the foundation through 14-foot screw holes. Adjusting pads allow for precise horizontal positioning. The design includes a strategically placed hole beneath the front part of the machine base and the back cavity of the positive pressure plate to accommodate sand leakage, which can be efficiently cleaned out through removable cover plates on both sides.
2. Cavity frame: Comprised of upper and lower frames, side frames, top, side, and bottom plates, guide pillars, back frame (support cylinder), and cross brackets, this assembly ensures easy replacement of the cavity working surface. The working surfaces are conveniently connected to the frame with screws, allowing for swift changes without dismantling the molding chamber frame.
3. Positive pressure plate mechanism: This sophisticated mechanism includes a plate body, heater, vibrator, and stroke position slide tube. The positive pressure plate is intricately connected to the piston of the front cylinder, facilitating compaction, pushing, closing, starting mold 2, and other processes. A position sensor provides accurate feedback on the plate's position, while adjustable sliding pads ensure piston-cylinder concentricity during movement, enhancing precision and performance.
4. Counter-pressure Plate Mechanism: A sophisticated assembly, the counter-pressure plate mechanism is meticulously crafted with a plate body, heating liner, heater, and vibrator. It also features a meticulously engineered sand blowing clean nozzle and a counter-pressure plate frame, all interconnected through a four-link mechanism. The entire setup is seamlessly linked to the piston of the counter-pressure plate cylinder via four guide pillars and cross brackets. This ingenious design facilitates the execution of two critical processes: initiating mold 1 and closing the cavity. Position signals are precisely relayed by a sensor on the guide pillar, ensuring accuracy. For horizontal adjustments, the counter-pressure plate body aligns seamlessly with the machine's precision standards, while the four adjusting pillars guarantee perfect vertical alignment with the bottom plate during sand shooting and mold initiation.
5. Sand Injection System: This pivotal component is expertly constructed with a gas storage tank, sand injection cylinder, and sand gate mechanism, complemented by a sand injection valve, quick discharge valve, and material level meter. The sand injection pressure, ranging from 0.3MP to 0.4MP, is meticulously controlled by two pressure-reducing valves. Electrical control permits optimal timing of the sand injection valve opening, ensuring that the sand injection cylinder holds approximately 1.5 times the normal sand type volume. A strategically placed level meter signals the sand adding machine to halt sand addition and secure the sand gate once optimal sand volume is reached.
6. Oil Cylinder: Ingeniously aligned along the coaxial line, the oil cylinder consists of a front cylinder for positive platen movement and a rear cylinder for reverse platen movement. This innovative design adopts a combined cylinder form, ensuring that during all processes except compaction, the pressure oil enters only the small area oil cavity. This clever mechanism ensures rapid piston movement, enhancing overall machine efficiency and precision.
7. Hydraulic System Principle Description
Within this robust hydraulic system, standard components are strategically utilized. The oil circuit is bifurcated into the control oil circuit and the working oil circuit. A duplex vane pump powers the control oil circuit, deftly adjusting the swing angle of the oil pump for desired variable speed piston movement to suit machine operations. User-defined compaction pressure values, ideally set between 7-9MP, work seamlessly with combined type force values adjusted to 4-5MP. The pressure sensor intricately regulates the machine's compaction ratio, modifying pressure values to enhance compaction efficacy. When adjustments are made, the three-stage overflow is also recalibrated. To maintain optimal operation, the tubular heater, cooler, and oil temperature measuring sensor, along with its control oil circuit, ensure stable oil temperatures between 35-45 degrees.
8. Electrical System Principle Description
The electrical system harnesses the power of AC 380V supply (requiring a three-phase five-wire system), while the control circuit operates on AC 220V. Offering unparalleled versatility, the machine supports manual, single-action, full-line linkage, and manual down core functionalities. Equipped with start, stop, stop, and emergency stop buttons, the main machine flawlessly transitions through its process: cavity closing, sand shooting, compaction, mold starting 1, mold ejection, mold closing, and mold starting 2. In emergency scenarios, seamless stopping mid-process or an emergency stop is achievable. The emergency stop cuts off power to the control segment, while midway stops interrupt the solenoid valve output. When resuming, the machine restarts from the previous stop point and cycles through to the initial position.
