<p>A coupling device which contributes to a further reduction in the space require to transport a die etc., in which first and second joints are simplified in structure and downsized, and that is advantageous when multiple sets of such first and second joints are installed. The coupling device 15 comprises a female joint 20 and a male joint 25. The female joint 20 is fitted on a mold M2 and comprises a first valve casing 30, a first valve body 35, and a first open/close valve 45 having a first valve seat 31 and a first valve portion 36. The male joint 25 is fitted on a clamping plate 11 of an injection molding machine and comprises a second valve casing 50, a second valve body 55, and a second open/close valve 65 having a second valve seat 51 and a second valve portion 56. The coupling device further comprises a valve body drive unit 70. When, in a condition where the front ends of the first and second valve casings 30 and 50 are in contact with each other, the valve body drive unit 70 drives and advances, in the male joint 25, only the second valve body 55 relative to the second valve casing 50, the first and second valve bodies 35 and 55 are driven to the valve opening side.</p> |
