The invention relates to a self-locking type overturning high-pressure forming
machine. The self-locking type overturning high-pressure forming
machine which comprises a main rack, a die trolley A, a die trolley B, a middle base plate, a
tail end base plate, a self-
locking mechanism, an overturning mechanism, a die opening and closing mechanism, a mud pressurizing mechanism, a hydraulic device, a
pressure sensor and a control device, wherein the main rack is used for overall mechanism carrying, the die trolley A and the die trolley B are used for carrying a die for moving, the middle base plate and the
tail end base plate are used for fixing a main
machine base plate of the die, the self-
locking mechanism is used for
self locking of the die, the overturning mechanism is used for overturning the die, the die opening and closing mechanism is used for opening and closing the die, the mud pressurizing mechanism is used for pressurizing mud, and the hydraulic device is used for providing hydraulic power for the self-
locking mechanism. According to the self-locking type overturning high-pressure forming machine, automatic die opening and closing are conducted, die releasing is conducted in an overturning and unified manner, and the equipment comprehensive running efficiency is improved; and the self-locking mechanism is adopted, the structure is simple, use is convenient, and consumption of manpower,
material resources and financial resources can be effectively reduced.
