Vertical Parting Boxless Molding Machine This advanced Vertical Parting Boxless Molding Machine is tailor-made for the mass production of small to medium-sized cast iron components, such as gray, malleable, and ductile iron. It excels with unmatched production efficiency and delivers castings with superior dimensional precision and surface quality. The machine operates with whispering low noise levels and reduces labor intensity, featuring a streamlined group line that requires minimal auxiliary machinery. Its compact design leads to lower labor and construction costs, while also promoting energy savings and an excellent working environment.
Characteristics of the Molding Machine:
1. The electrical system is enhanced with imported Mitsubishi programmable controllers (PLC) that centralize the automatic control of both main and auxiliary machines. The PLC programming is intuitive and easily adjustable, offering robust anti-interference capabilities, stable operation, and a meticulously crafted program complete with self-locking protection and fault detection functions.
1. Machine Base: Constructed primarily from welded structural elements, the machine base serves as the cornerstone, supporting all other machine parts. It features 14 foot screw holes for solid foundation attachment, with adjustable pads ensuring the machine's horizontal alignment. Front section holes accommodate sand leaks from the platen slit, with removable cover plates on both sides for easy sand clearance.
2. Cavity Frame: A robust assembly of upper and lower frames, side frames, top, side, and bottom plates, guide pillars, back frame (supporting cylinder), and cross brackets. The top, bottom, and side plates of the working surface are securely screwed to the frame, allowing for effortless replacement without dismantling the molding chamber's frame.
3. Positive Pressure Plate Mechanism: Comprising a plate body, heater, vibrator, and stroke position slide tube, this mechanism is pivotal. The positive pressure plate links to the front cylinder piston, moving in tandem to execute compaction, pushing, and closing actions, and initiating mold 2 processes. Height-adjustable sliding pads ensure alignment, keeping the piston concentric with the cylinder during operations.
4. Counter-pressure Plate Mechanism: This sophisticated mechanism is a marvel of engineering, primarily comprised of the plate body, a heating liner, a heater, a vibrator, a sand blowing clean nozzle, a counter-pressure plate frame, a four-link mechanism, and more. Ingeniously connected to the counter-pressure plate cylinder piston via four guide pillars and cross brackets, it operates seamlessly with the piston to execute two critical processes: initiating the mold and closing the cavity. The precise position of the counter-pressure plate is relayed by a position sensor on the guide pillar, allowing for fine horizontal adjustments to enhance the machine's overall accuracy. Furthermore, the four adjusting pillars on the counter-pressure plate frame ensure the plate remains perfectly vertical with the bottom plate during sand shooting and mold initiation.
5. Sand Injection System: Engineered for precision and efficiency, this system features components such as a gas storage tank, sand injection cylinder, sand gate mechanism, sand injection valve, quick discharge valve, and material level meter. The sand injection pressure in the gas tank is meticulously controlled by two pressure reducing valves, generally maintained between 0.3MP-0.4MP. The opening time of the sand injection valve is finely tuned via electrical control, ensuring the sand injection cylinder holds approximately 1.5 times the capacity of a standard sand type. Once at full capacity, the level meter signals the sand adding machine to cease operations and close the sand gate, maintaining optimal operational efficiency.
6. Oil Cylinder: Ingeniously designed for optimal performance, the system features a front cylinder (driving positive platen movement) and a rear cylinder (driving reverse platen movement), both aligned coaxially. The cylinder embraces a modular form, and outside the compaction process, the pressure oil from the working oil circuit only enters the small area oil cavity, enabling rapid piston movement for increased efficiency.
7. Hydraulic System Principle Description
Within this advanced hydraulic system, components are predominantly standard parts. The system is split into two distinct circuits: the control oil circuit and the working oil circuit. Powered by the duplex vane pump, the control oil circuit's primary pressure oil manipulates the oil pump's swing angle, facilitating the cylinder piston's variable speed movement to meet diverse operational needs. For compaction, the recommended pressure is 7-9MP, while a combined type force value is fine-tuned to 4-5MP. A pressure sensor meticulously oversees the machine’s compaction ratio pressure, allowing for adjustments to enhance performance. If the pressure sensor’s calibration is altered, the three-stage overflow must be adjusted correspondingly. The oil temperature control link, comprising a tubular heater, cooler, and oil temperature sensor, ensures consistent oil temperature between 35-45 degrees, promoting the hydraulic system's stable operation.
8. Electrical System Principle Description
The electrical system is an epitome of modern engineering, powered by AC 380V (necessitating a three-phase five-wire system) and an AC 220V control circuit. It offers versatile operational modes including manual, single-action, full-line linkage, and a manual down core function, all controllable through start, stop, emergency stop, and conventional stop buttons. The main machine's operational flow progresses through cavity closing, sand shooting, compaction, mold starting 1, mold ejection, and mold starting 2. In emergencies, a mid-cycle stop is achievable by disconnecting the solenoid valve output, while the emergency stop cuts the control part's power supply. Upon resumption, operations begin from the halt location, and the system undergoes a full cycle at the starting position when the stop button is pressed, ensuring seamless functionality.
