Abstract
The utility model discloses a thermostatic control device of a material cylinder for an injection machine, comprising a cylindrical shell connected with the injection machine, a threaded groove is arranged on the outer surface of the cylindrical shell, the cylindrical shell is inserted into a cylinder sleeve with more than one air inlets and exhaust outlets, and the air inlets are connected with an external gas source. By using the air-cooled control, the accuracy of the heating temperature of the material cylinder of the injection machine can be controlled to be about +/- 0.5, thus achieving the high accuracy of the plastic dissolving temperature.
Description
Technical field
The utility model relates to the injection machine field in the machinery, especially is installed in the barrel on the vertical injection molding machine, can control barrel temperature by thermostatically-controlled equipment.
Background technology
Along with development in science and technology, the extensive use of various plastic products, increasing plastic product is in forming process, more and more higher to the dissolving plastic control accuracy of temperature, as the moulding of the PVC that uses in medical device product the susceptibility of temperature just there is very high requirement, requires accurately ± 1 about degree.At present, the accuracy of common electric elements control temperature can only can not satisfy these plastics far away to the high sensitive requirement of temperature about ± 6 degree.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of barrel temperature control of injection mold device, uses this control system, can be controlled at the accuracy of injecting machine material tube heating-up temperature ± 0.5 degree about, reach the high precision of control dissolving plastic temperature.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of injecting machine material tube thermostatically-controlled equipment, comprise the cylindrical shell that is connected with injection machine, described barrel outer surface is provided with thread groove, described cylindrical shell is inserted in the jacket casing, described jacket casing is provided with more than one air inlet and exhaust outlet, and described air inlet is connected with external air source by pipeline.In the injection moulding process, barrel needs constantly to heat the material in the barrel is plastified, and the plasticizing rate of material directly has influence on injection-molded finished quality.In the utility model, when the barrel heating-up temperature is too high, external air source is by the air inlet inflation of pipeline to jacket casing, the gases at high pressure that enter between jacket casing and the cylindrical shell can be along the thread groove migration of drum surface under the effect of pressure, the gas of this part can be taken away the heat of a drum surface part, and the gas that has absorbed heat discharges by the exhaust outlet in the middle of the jacket casing, thereby a part of heat of barrel is distributed to the external world, accelerated the heat radiation of cylindrical shell, barrel temperature is descended.After barrel temperature dropped to certain value, external air source stopped inflation and waits for when high temperature appears in barrel next time and restarting, to realize accurately controlling barrel temperature.
As improvement, described jacket casing and cylindrical shell are interference fit.Prevent that gas from leaking, guarantee that gas fills air inlet and enters, discharge from exhaust outlet along thread groove then.
As improvement, jacket casing is provided with two air inlets and an exhaust outlet, and described air inlet is separately positioned on the jacket casing two ends, and exhaust outlet is arranged on the centre of jacket casing, and corresponding air inlet and exhaust ports are provided with cannelure on the cylindrical shell.Gas enters from the air inlet at jacket casing two ends, discharges from the middle exhaust outlet of jacket casing then, cylindrical shell is divided into two sections dispels the heat, and makes the heat radiation of barrel more even.
As improvement, described air inlet and pipeline junction are provided with air intake valve, and described exhaust outlet is provided with drain tap.Realize the control that gas passes in and out in the jacket casing by air intake valve and drain tap, make that barrel temperature control is more convenient.
As improvement, also be provided with the temperature-detecting device of controller and detection barrel temperature, described temperature-detecting device, air intake valve, drain tap all are connected with controller.When temperature surpasses design temperature when barrel heats, controller control air intake valve and drain tap are opened, and external air source is inflated in jacket casing, discharges from exhaust outlet then, barrel is carried out air circulation cool, reach design temperature up to actual temperature and just close.
The beneficial effect that the utility model is compared with prior art brought is:
Cylindrical shell is provided with thread groove, and gas is by taking away a part of heat of barrel, this radiating mode more convenient and quicker, and good heat dissipation effect in the thread groove migration;
Described jacket casing and cylindrical shell are interference fit, prevent that gas from leaking, and guarantee that gas fills air inlet and enters, and discharge from exhaust outlet along thread groove then;
Temperature-detecting device, controller, air intake valve, drain tap cooperatively interact, and jointly barrel are carried out thermostatic control, and simple to operate, temperature is controlled accurately.

The specific embodiment
As shown in Figure 1, 2, a kind of injecting machine material tube thermostatically-controlled equipment comprises the cylindrical shell 1 that is connected with injection machine, and described cylindrical shell 1 outer surface is provided with thread groove 5, and described cylindrical shell 1 is inserted in the jacket casing 2, and described jacket casing 2 is an interference fit with cylindrical shell 1.Jacket casing 2 is provided with two air inlets 3 and an exhaust outlet 4, and described air inlet 3 is separately positioned on jacket casing 2 two ends, and exhaust outlet 4 is arranged on the centre of jacket casing 2, and corresponding air inlet 3 and exhaust outlet 4 places are provided with cannelure 6 on the cylindrical shell 1.Described air inlet 3 is provided with air intake valve (not indicating) with pipeline junction, and described exhaust outlet 4 is provided with drain tap (not indicating), and air intake valve is connected with external air source (not indicating) by pipeline.Described cylindrical shell is provided with temperature-detecting device, and described temperature-detecting device (not indicating), air intake valve, drain tap all are connected with controller (not indicating).In the injection moulding process, barrel needs constantly to heat the material in the barrel is plastified, and the plasticizing rate of material has directly influenced injection-molded finished quality.In the utility model, when temperature surpasses design temperature when barrel heats, controller control air intake valve and drain tap are opened, external air source is by air inlet 3 inflations of pipeline to jacket casing 2, the gases at high pressure that enter between jacket casing 2 and the cylindrical shell 1 can be along 5 migration of cylindrical shell 1 thread surface groove under the effect of pressure, because jacket casing 2 is an interference fit with cylindrical shell 1, make that the gas that enters in the jacket casing 2 can only be along thread groove 5 migration, the gas of this part can be taken away the heat of cylindrical shell 1 a surface part, the gas that has absorbed heat discharges by the exhaust outlet 4 in the middle of the jacket casing 2, thereby a part of heat of barrel is distributed to the external world, accelerated the heat radiation of cylindrical shell 1, barrel temperature is descended.After barrel temperature drops to certain value, temperature-detecting device sends signal to controller, controller control air intake valve and drain tap are closed, and external air source stops inflation and waits for when high temperature appears in barrel next time and restarting, to realize accurately controlling barrel temperature.
A kind of barrel temperature control of injection mold device of the present utility model uses this control system, can be controlled at the accuracy of injecting machine material tube heating-up temperature ± 0.5 degree about, reach the high precision of control dissolving plastic temperature.
