PURPOSE: A pair of hot runner valves installed in one manifold are provided to produce a pair of molded objects simultaneously in a hot runner valve as a plastic product molding device by installing a pair of hot runner valves(a piston and a hot runner) in one manifold in a straight line. CONSTITUTION: A pair of one-side-open square cylinders(5) is formed in both portions of a manifold(1). A piston(P) having its pin head(10) of a valve pin(7) fixed to each end of piston rods(3,3') in both sides of a piston body(2) by upper and lower holders(4,4') is installed to reciprocate in the cylinder. An internal sprue runner(11) of a hot runner valve is connected with another sprue runner(12) branched in the shape of T in a manifold(1).
