[0026] In summary, this special mold for automotive parts production, designed for easy maintenance, utilizes a pusher assembly 6. When disassembly and maintenance are required, the dual-axis servo motor 91 is activated, driving two threaded shafts 93 to rotate via the output shaft. This causes two threaded retaining cylinders 94 to move relative to each other until they are removed from the interior of the two connecting shafts 10. At this point, the mold 5 is pulled upwards, causing the connecting shafts 10 to be extracted from the mounting cavity 7, thus facilitating mold disassembly and improving the maintenance efficiency of the device. Simultaneously, the stamping block 13 can be removed by rotating the limit bolt 16, facilitating device maintenance and enhancing its practicality. By activating the pusher assembly 6, the electric push rod 61 is activated, driving the ejector plate 62 upwards via the output end to push out the processed parts inside the mold 5, facilitating demolding and further improving the device's practicality. This design addresses some shortcomings of existing special molds for automotive parts production, such as the difficulty in disassembling the mold, increased maintenance difficulty for operators, and reduced maintenance efficiency.
