Description
Technical field
The present invention relates to injection mold technical field, particularly a kind of injection mold fast temperature control method.
Background technology
Injection mold is the important process equipment of producing various industrial products, along with developing rapidly of plastics industry, and plastic products are the applying of the industrial departments such as Aeronautics and Astronautics, electronics, mechanical boats and ships and automobile, injection mold is widely used in industry-by-industry.Traditional injection moulding mould is comprised of dynamic model and cover half two parts, and dynamic model is arranged on the moving die plate of injection (mo(u)lding) machine, and cover half is arranged on the fixed form of injection (mo(u)lding) machine.Dynamic model and cover half closed formation running gate system and die cavity when injection moulding, during die sinking, dynamic model is separated with cover half to take out plastic products.Injection mold is mainly comprised of running gate system, thermoregulating system, forming part and constitutional detail.For thermoplastic injection mould, thermoregulating system is mainly that design cooling system makes mold cools down.The conventional way of mold cools down is in mould, to offer fluid passage, utilizes the cooling water circulating to take away the heat of mould; The heating of mould is to utilize fluid passage to pass into hot water or steam.The heating of this mould or cooling be generally all to regulate according to worker's experience, so the temperature of mould can not get accurate control, thereby affected the Forming Quality of product.
Summary of the invention
The object of the invention is to overcome the shortcoming of prior art, provide a kind of temperature degree of regulation high, guarantee forming quality of products, facilitate thermoregulator injection mold fast temperature control method.
Object of the present invention is achieved through the following technical solutions: a kind of injection mold fast temperature control method, and it comprises the following steps:
S1, fluid passage is set in injection mold, a port of fluid passage is connected to feed tube, another port of fluid passage is connected to drain pipe, feed tube is connected to cooling fluid carrier pipe by an arm, feed tube is connected to heating fluid carrier pipe by another arm, on the arm of feed tube that connects cooling fluid carrier pipe, magnetic valve A is set, on the arm of feed tube that connects heating fluid carrier pipe, magnetic valve B is set, set temperature sensor in die ontology, is electrically connected to temperature sensor, magnetic valve A and magnetic valve B respectively with controller;
When the temperature of S2, the die ontology that detects when temperature sensor is less than setting value, controller controls magnetic valve A and cuts out, controls magnetic valve B unlatching, thereby the fluid passage in die ontology passes into heating fluid, and die ontology is heated, and then make the temperature of die ontology rise to setting value;
When the temperature of S3, the die ontology that detects when temperature sensor is greater than setting value, controller is controlled magnetic valve A unlatching, control magnetic valve B closes, thereby the fluid passage in die ontology passes into cooling water, die ontology is carried out cooling, make the temperature of die ontology drop to setting value.
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 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 guaranteed the Forming Quality of product.Fluid passage is the structure that is provided with a plurality of heater mounting hole on snakelike or annular setting, die ontology and has guaranteed that die ontology is cooling, the uniformity of heating in die ontology inside, be beneficial to equally the Forming Quality that improves product.
