The production device of the liquid cooling charging cable for the electric automobile according to claim 2, wherein a vacuum pump (15) is fixedly arranged on the front surface of the mounting frame (10), a vacuum air guide frame (16) is fixedly arranged on the front side of the inside of the mounting frame (10), a rotary air guide ring (17) is rotatably arranged in the vacuum air guide frame (16), the inside of the rotary air guide ring (17) is communicated with the inside of the vacuum air guide frame (16), four vacuum exhaust pipes (32) are further communicated in the inside of the rotary air guide ring (17), and one ends of the four vacuum exhaust pipes (32) are respectively communicated with the inside of the four cooling dies (14).
4. The apparatus for producing a liquid-cooled charging cable for an electric vehicle according to claim 3, wherein the apparatus for producing a liquid-cooled charging cable for an electric vehicle operates in a manner comprising the steps of:
The liquid cooling charging cable of the extrusion sheath enters the device from a processing through groove (11) at the top of the mounting frame (10), and the die changing servo motor (12) drives the die changing rotating frame (13) to rotate so as to rotate a cooling die (14) with proper cable specification to a processing position;
The servo motor (25) is controlled to start, the rotating screw rod (24) is driven to rotate, and the external threads with opposite rotation directions are used for driving the adjusting thread blocks (31), so that the two matching modules of the cooling die (14) slide relatively along the adjusting groove (23) until the surface of the cable is tightly covered;
The staggered sealing connecting frames (27) and the elastic sealing gaskets form a labyrinth sealing structure, so that the pressure on the surface of the cable is reduced, gas leakage is prevented, and the vacuum pump (15) is matched to vacuumize the inside of the cooling die (14) through the vacuum air guide frame (16), the rotary air guide ring (17) and the vacuum air extraction pipe (32), so that heat dissipation is accelerated, and the surface quality is improved;
the miniature electric cylinder (28) drives the cooling heat exchange plate (29) to be attached to the cable, a cooling medium flows into the cooling medium guide ring (19) through the cooling material receiving port (18), and enters the circulating heat exchange flow channel (30) in the cooling heat exchange plate (29) through the cooling medium circulating pipe (20) and the elastic connecting conduit (26) to flow in the direction opposite to the cable conveying direction, so that efficient heat exchange is realized, and cooling shaping is completed;
The electric control valve controls the on-off of the vacuum exhaust pipe (32), and the position of the cooling heat exchange plate (29) is adjusted by combining the miniature electric cylinder (28), so that the cooling process is accurately controlled, and the method is suitable for different production requirements.
