Vertical Parting Boxless Molding Machine This machine is ideal for high-volume production of small to medium-sized cast iron parts, such as gray, malleable, and ductile iron. It boasts superior production efficiency, along with remarkable dimensional accuracy and surface quality of the castings. The design ensures low noise levels, reduced labor intensity, a straightforward assembly line, and minimal space requirements for auxiliary machinery. Investment in labor and construction is significantly reduced, featuring energy-efficient operations and an enhanced working environment.
Characteristics of the Molding Machine:
1. The electrical system is equipped with a premium Mitsubishi programmable controller (PLC) for streamlined, automatic control of both the main and auxiliary machines. This setup offers straightforward PLC programming and adjustments, coupled with exceptional anti-interference capability. The machine operates seamlessly with a thoughtfully designed program featuring comprehensive self-locking protection and fault detection functions.
1. Machine Base: Constructed from robust welded structural parts, the machine base provides foundational support for all other components. It is securely anchored to the foundation using 14 foot screw holes, with adjustable pads ensuring horizontal alignment. The base is ingeniously designed with a front hole and back cavity to capture sand leakage, with removable cover plates for easy cleaning access.
2. Cavity Frame: This assembly includes upper and lower frames, a side frame, top plate, side plate, bottom plate, guide pillar, back frame (supporting cylinder), and cross bracket. The working surface plates are easily replaceable, securely attached to the frame with screws, allowing for seamless maintenance without disassembling the molding chamber frame.
3. Positive Pressure Plate Mechanism: Constituting a plate body, heater, vibrator, and stroke position slide tube, this mechanism is connected to the front cylinder piston. It moves in sync with the piston to perform functions such as compaction, pushing, and closing, along with initiating mold 2 processes. Height-adjustable sliding pads ensure the piston remains concentric with the cylinder during movement, facilitated by a position sensor signaling the positive pressure plate's position.
4. Counter-pressure Plate Mechanism: This sophisticated assembly primarily comprises a plate body, heating liner, heater, vibrator, sand-blowing clean nozzle, counter-pressure plate frame, and a four-link mechanism, among other components. Ingeniously connected to the counter-pressure plate cylinder piston via four guide pillars and cross brackets, it gracefully synchronizes with the piston to execute the dual processes of mold starting and cavity closing. A position sensor on the guide pillar transmits precise position signals, facilitating the horizontal adjustment of the counter-pressure plate body to ensure the machine's unparalleled accuracy. The four adjustable pillars on the counter-pressure plate frame meticulously align the counter-pressure plate vertically with the bottom plate, optimizing conditions for seamless sand shooting and mold starting.
5. Sand Injection System: An advanced ensemble, it primarily features a gas storage tank, sand injection cylinder, sand gate mechanism, sand injection valve, quick discharge valve, and material level meter. The sand injection pressure within the gas tank is expertly regulated by two pressure-reducing valves, typically maintained between 0.3MP and 0.4MP. The sand injection valve's opening duration is finely tuned via electrical controls, and the sand injection cylinder holds up to 1.5 times the amount of a sand type. Once the sand capacity is reached, a level meter sends a signal to halt the sand adding machine, thereby closing the sand gate for controlled operations.
6. Oil Cylinder: Strategically arranged along the coaxial line, the front cylinder propels the positive platen while the rear cylinder drives reverse platen movement. Embracing a combined cylinder form, it facilitates rapid piston movement through the entry of pressure oil into the small area oil cavity during non-compaction processes, ensuring efficiency and swift operations.
7. Hydraulic System Principle Description
The hydraulic system is characterized by its standard componentry. The oil circuit is bifurcated into the control oil circuit and the working oil circuit. The duplex vane pump supplies the control oil circuit, where the first level pressure oil meticulously governs the oil pump's swing angle to enable the cylinder piston's variable speed movement, aligning with operational requisites. Users can set the compaction pressure adjustment value, typically recommended between 7-9MP, while the combined type force is adjusted to 4-5MP. A pressure sensor oversees the machine’s compaction ratio pressure, and any adjustments in pressure values necessitate a corresponding adjustment in the three-stage overflow. The oil temperature remains stabilized between 35-45 degrees through the tubular heater, cooler, and oil temperature measuring sensor, ensuring the hydraulic system's stable performance.
8. Electrical System Principle Description
The electrical system is designed for optimal performance, operating on an AC 380V power supply (three-phase five-wire system) with the control circuit powered by AC 220V. The machine boasts manual, single-action, full-line linkage, and manual down-core functionalities, complete with start, stop, and emergency stop buttons. Its process flow features sequential stages: cavity closing, sand shooting, compaction, mold starting 1, mold ejection, mold closing, and mold starting 2. In emergencies, the system allows for mid-process halts through the emergency stop, cutting off control power, while a middle stop disconnects the solenoid valve output. Upon resumption, the machine seamlessly continues from the stop location, with the entire line cycling back to the initial position to ensure smooth operations.
