PURPOSE:To enable to readily perform injection molding of different right and left side molds by communicating with any of the right and left side molds between the right and left side molds constructing a captioned injection molding machine and associating a switching valve having a port which can close the other of the molds. CONSTITUTION:Hot runner manifold blocks 3 are arranged in the intermediate between right and left molds 2 and 2, any of the molds 2, 2 is allowed to communicate at the position of the branch of secondary runners 6a, 6a with the main runner 6a of the blocks 3, and a switching valve 10 having an operating handle 12 with a port 11 which closes the other of the molds 2, 2 is associated. In this structure, when the valve 10 in which the port 11 is contacted with the left side secondary runner 6a is disposed, an injection molding can be performed with the left side mold 2 and an injection nozzle 14, while when the valve 10 is switched to the opposite side, the injection molding can be performed with the right side mold 2. |
