Abstract
The utility model discloses a temperature adjusting device in an injection mould. The temperature adjusting device comprises a heating unit and a cooling unit, wherein the heating unit comprises a temperature sensor, a temperature controller and an infrared heating pipe; the temperature sensor is connected with an input end of the temperature controller by a lead wire; an output end of the temperature controller is connected with the infrared heating pipe; the cooling unit comprises a cooling pipe, a pressure adjusting device, a temperature sensor, a controller and an electric control water feeding valve; the cooling pipe comprises a water feeding pipe and a water discharging pipe; the electric control water feeding valve is arranged on the water feeding pipe; the pressure adjusting device, the temperature sensor and the controller are arranged on the water discharging pipe. With the adoption of the temperature adjusting device in the injection mould, the automatic adjustment of the temperature of the mould is realized so that the temperature of the mould can be uniformly and accurately controlled, and the product formation quality is guaranteed.
Description
Technical field
The utility model relates to a kind of temperature-adjusting device, is specifically related to the temperature-adjusting device in a kind of injection mold.
Background technology
Injection mold is a kind of instrument of producing plasthetics, is also the instrument of giving plasthetics complete structure and accurate dimension.Injection mold is made up 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 in the time of injection moulding, when die sinking, dynamic model separates to take out plastic products with cover half.Injection mold is mainly made up 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 cooling-water duct, utilizes the cooling water circulating to take away the heat of mould; The heating of mould is to utilize cooling-water duct 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 product shaping quality.
Utility model content
The technical problem that the utility model solves is to overcome the temperature of mould in prior art to can not get accurate control, maintenance that can not be stable, thus affect product shaping quality.In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: the temperature-adjusting device in injection mold, comprise and add heat unit and cooling unit, the described heat unit that adds comprises temperature sensor, temperature controller and infrared ray heating tube, described temperature sensor is connected by wire with the input of described temperature controller, the output of described temperature controller is connected with described infrared ray heating tube, when described temperature sensor senses is to the temperature of mould during lower than design temperature, infrared ray heating tube work described in described temperature controller control, described cooling unit comprises cooling tube, pressure-regulating device, temperature sensor, controller, automatically controlled water-supply valve, described cooling tube is divided into water inlet pipe and drainpipe, described automatically controlled water-supply valve is arranged on described water inlet pipe, described pressure-regulating device, temperature sensor and described controller are arranged on drainpipe, the temperature signal sensing is exported to described controller by the temperature sensor being arranged on drainpipe, supply water or close by automatically controlled water-supply valve described in described controller control.
Temperature-adjusting device in aforesaid injection mold, described infrared ray heating tube is multiple.The utility model beneficial effect is: by independently heating unit and cooling unit are set, can make mould obtain uniform heating and cooling.Wherein heating unit judges the temperature signal of temperature sensor collection by temperature controller, thereby controls the duty of infrared ray heating tube; The temperature signal that cooling unit gathers temperature sensor by controller judges, thereby controls opening or closing of automatically controlled water-supply valve.The pressure that pressure-regulating device can regulate pipeline is set in cooling unit, thereby prevents the excessive infringement of pipeline pressure mould.Technique scheme has realized the automatic adjusting to temperature, makes the temperature of mould can be precisely controlled, thereby has ensured product shaping quality.
