Summary of the invention
The technical problem to be solved in the present invention is to provide the temperature control system for mould that can improve heat utilization rate under a kind of prerequisite meeting equal technological effect function.
The temperature control system of a kind of mould of the present invention, is mainly comprised of die heater, and described die heater comprises computer board and instruction input block thereof, sensory feedback unit, display interface, heating performance element, cooling performance element, air blowing performance element, moisturizing performance element, voltage-stabilized power supply, by given instruction, parameter feedback, sequential operation, output execution realizes closed loop and automatically controls, and is the maincenter control section of system, and wherein, computer board is programmable microcomputer controller, and instruction input block comprises operation keyboard and USB interface, and sensory feedback unit comprises the temperature of each portion of the system of being arranged on, pressure, level sensor and input interface thereof, the display terminal that display interface is computer board, heating performance element, cooling performance element, air blowing performance element, moisturizing performance element is by relay, A.C. contactor forms, and by the electric power of each portion of electrical lead drive system, carries out components and parts, and each that is controlled by computer board be power switch performance element independently, and voltage-stabilized power supply is for providing the device of electric power to inner each electric operation of die heater.
System operation programs is: heating, emptying, cooling, emptying, is cycled to repeat; Moisturizing part is complete to the water filling of high temperature water tank via cooling tower, moisturizing filter, high-pressure hydraulic pump, moisturizing magnetic valve, check valve; Inject the water of high temperature water tank, by high temperature pressurised pump pump into electric boiler, superheater heats, again through the gain of heat that circulates of the circulating electromagnetic valve of circulation gain of heat bypass, high temperature water tank, high temperature pressurised pump, electric boiler, superheater that check valve is got back to pressure-reducing valve, the superheated vapor producing is stored in high temperature water tank and middle electric boiler, and in temperature, pressure arm-to-arm up to standard; Magnetic valves all in system are all in closed condition, and electric boiler and all pump are in controlled open/close states.When highlight mould is in die sinking heating tense, system enters heating schedule; When highlight mould enters mold-closing injection tense, system enters emptying, cooling program; When steam-heat and high-light mould enters die sinking demoulding tense, system enters emptying and heating schedule again; Emptying: the controlled cooling electric magnet valve of closing water-cooled part of cooling performance element of die heater, cooling water cut-off, the air blowing magnetic valve of the controlled unlatching air blowing of air blowing performance element part, compressed air enters combiner controlling unit by compressed air source, air blowing magnetic valve; Moisturizing: die heater is according to the input instruction of storage and the feedback that is arranged on the level sensor of high temperature water tank, and through computing, output control signal, by the moisturizing magnetic valve of moisturizing performance element open system moisturizing part.
The present invention has overcome the problems and shortcomings that energy consumption is large, heat utilization rate is low that prior art exists, a kind of energy-saving type highlight non-trace mold temp. controlling system providing, meeting under the prerequisite of equal technological effect function, reaching and improved heat utilization rate, energy-saving and cost-reducing object.
