This invention discloses a mold-closing device for injection blow molding production, comprising a device base, a cooling fan, and a second mold-closing cavity. A first support panel is welded to the top of the device base, and a second support panel is welded to the top of the first support panel. A gear disk is disposed above the second support panel, and a transmission chain meshes with the outer side of the gear disk. The cooling fan is installed directly below the second support panel. The first mold-closing cavity is disposed above the device base, and a connecting piece is disposed on the outer side of the first mold-closing cavity. A rotating rod is connected to the outer side of the gear disk. A connecting hole is provided through the outer side of the second mold-closing cavity, and a telescopic cylinder is connected to the back of the second mold-closing cavity. This mold-closing device for injection blow molding production uses a gear disk and bevel gears. The gear disk drives the first mold-closing cavity to slide horizontally, facilitating adjustment of the distance between the first and second mold-closing cavities as needed.
