摘要： A counterpressure/temperature control apparatus, comprises: a mold, having a runner and an air passage, both coupled to a mold cavity inside the mold; a logic control valve, coupled to the air passage for controlling a high-temperature gas or/and a counterpressure gas to flow in and out the mold cavity; a counterpressure gas supplying device, for supplying the counterpressure gas to the mold cavity through the logic control valve; and a high-temperature gas supplying device, for supplying the high-temperature gas to the mold cavity through the logic control valve; wherein the mold cavity is heated by the high-temperature gas, while subjecting the same to a counterpressure provided from the counterpressure gas supplying device during an injection molding process, and thereby, not only the surface quality of a product resulting from the injection molding process can be improved, but also the size of foams and the distribution evenness thereof are enhanced.
