Summary of the invention
The object of the invention is to overcome the shortcoming of prior art, the temperature control method that a kind of temperature degree of regulation is high, ensure the heat recovery type injection mold of forming quality of products is provided.
Object of the present invention is achieved through the following technical solutions: a kind of temperature control method of heat recovery type injection mold, and it comprises the following steps:
S1, cooling-water duct and heater mounting hole are set in injection mold, preferably, cooling-water duct is snakelike or annular setting, electric heater is installed in heater mounting hole, a port of cooling-water duct is connected to water inlet pipe, another port of cooling-water duct is connected to outlet pipe, the delivery port of cooling water storage tank is connected to water inlet pipe by delivery pump, magnetic valve is installed on water inlet pipe, outlet pipe is connected successively to the water inlet of heat exchanger and cooling water storage tank, set temperature sensor in die ontology, by electric heater, magnetic valve, delivery pump and temperature sensor are electrically connected with controller respectively,
When S2, the temperature of die ontology detecting when temperature sensor are less than setting value, controller control delivery pump quits work, shut electromagnetic valve, thereby stop passing into cooling water to the cooling-water duct in die ontology, simultaneously, the work of controller control electric heater, die ontology is heated, and then make the temperature rise of die ontology to setting value;
S3, when the temperature of die ontology detecting when temperature sensor is greater than setting value, controller control magnetic valve is opened, control delivery pump is started working, thereby the cooling-water duct in die ontology passes into cooling water, simultaneously, controller control electric heater quits work, and then make the temperature of die ontology drop to setting value, after the cooling water that completes heat exchange with die ontology is heated through the outlet pipe heat exchanger of flowing through, absorbed the heat energy of cooling water by heat exchanger, cooling water is lowered the temperature again simultaneously, cooling water after cooling returns to cooling water storage tank through the water inlet of cooling water storage tank.
The present invention has the following advantages: the present invention detects the temperature of die ontology in real time by temperature sensor, and by controller, the temperature signal of temperature sensor collection is judged, thereby control the work of electric heater, delivery pump and the keying of magnetic valve, and then realize mould is carried out to heating and cooling, make die ontology in design temperature, realized the automatic adjusting to die ontology temperature, degree of regulation is high, has ensured the Forming Quality of product.Cooling-water duct is the structure that is provided with multiple heater mounting hole on snakelike or annular setting, die ontology and has ensured that die ontology is cooling, the uniformity of heating in die ontology inside, be beneficial to equally the Forming Quality that improves product.After the cooling water that completes heat exchange with die ontology is heated through the outlet pipe heat exchanger of flowing through, absorbed the heat energy of cooling water by heat exchanger, cooling water is lowered the temperature again simultaneously, cooling water after cooling returns to cooling water storage tank through the water inlet of cooling water storage tank, thereby cooling water circulation is used, avoided the waste of water resource and heat energy.
