QUICK-CHANGE-TYPE DOUBLE-LAYER-PISTON THREE-DIMENSIONAL COOLED AIR CYLINDER
Document Type and Number:
WIPO Patent Application WO/2020/252603
Kind Code:
A1
Abstract:
Disclosed is a quick-change-type double-layer-piston three-dimensional cooled air cylinder, comprising an air cylinder top cover (1) and an upper-layer piston (2). The upper-layer piston (2) is arranged in the interior below the air cylinder top cover (1), a partition plate (3) is arranged below the upper-layer piston (2), a piston connection screw (4) is inserted in the partition plate (3) at the middle position, a lower-layer piston (5) is arranged below the partition plate (3), an air cylinder bottom cover (6) is arranged at an outer end of the bottom of the lower-layer piston (5), an air cylinder rotary fixing plate assembly (7) is arranged at the bottom of the air cylinder bottom cover (6), air cylinder fixing screws (202) are arranged at four corners of the bottom of the air cylinder rotary fixing plate assembly (7), air cylinder fixing plate fixing screws (201) are circumferentially arranged at the middle of the air cylinder rotary fixing plate assembly (7), outer walls of the left sides and right sides of the air cylinder top cover (1) and the air cylinder bottom cover (6) are respectively provided with water path inlet/outlet connection ports (203) and air path inlet/outlet connection ports (204), an air cylinder top cover water path structure (205) is inserted in the air cylinder top cover (1), and an air cylinder bottom cover water path structure (206) is inserted in the air cylinder bottom cover (6). The air cylinder has a compact structure and a small size, and is easy to mount and dismount, air cylinder top cover water paths and bottom cover water paths internally communicate to form a three-dimensional water cooling circulation system, a water path cooling plate is omitted, the height of a cylinder body is reduced, the optimal angle of a cylinder body assembly can be selected from a range of 360 degrees according to a mold structure and a hot nozzle, and angle adjustment is convenient and rapid.
