Abstract
The utility model discloses a high-finish and melted marks-free injection mould, and belongs to the technical field of a mould. The mould comprises a static mould and a movable mould. The movable mould comprises a mould cavity plate; an injection hole is formed on the mould cavity plat and communicated with an injection moulding machine; a mould cooling plate is arranged between the mould cavity plate and the injection moulding machine; and the injection mould is also provided with a controller; and the controller is connected with a heater, a temperature sensor and the injection moulding machine respectively. The mould can also obtain the high optical and weld mark-free plastic products when the routine plastic injection process is adopted.
Description
Technical field
The utility model relates to a kind of mould, is specifically related to a kind of Gao Guang, does not have molten trace injection-die.
Background technology
Injection moulding all is widely used in industrial every field as one of forming method important in the plastic processing.Along with plastic products use increasingly extensive, people are more and more higher to the requirement of precision, surface quality and the intensity of plastic products, still, and for some defectives in the injection moulding process, as: weld mark, current mark, plastic products presentation quality difference etc., common injection molded technology can't solve at all.In actual production process, mainly improve the surface quality and the surface strength of plastic products, thereby cover up the blemish of plastic products by the plastic spraying technology.The surface spraying is the secondary operations to plastic product, adopts surperficial spraying technology, not only wastes raw materials for production, wastes energy, and increases the production cost of plastic products, and causes serious environmental to pollute, harm operating personnel's health of human body.
The high light of steam that occurred in nearly 2 years does not have the product that molten trace injection-die can obtain Gao Guang, not have molten trace, the technology that this mould adopted is in process of injection molding, with injection mold cavity or core rod quickly heat up near or be higher than the heat distortion temperature of polymer, then polymer is expelled in the mold cavity, in injection and pressure maintaining period, just begin quick cooling die die cavity or core rod, after mold temperature is cooled to a certain degree, open mould, take out product.But this mould requires to use high-temperature steam, the energy consumption height, and also security is low, and mould is produced complicated, and the user mode that colds and heat succeed each other simultaneously makes the life-span of die cavity and maintenance all have certain defective.
Summary of the invention
The purpose of this utility model is to provide a kind of Gao Guang, does not have molten trace injection-die, utilizes this mould when adopting conventional Shooting Technique, also can obtain Gao Guang, not have the plastic product that melts trace.
Its technical solution is: a kind of Gao Guang, the molten trace injection-die of nothing, comprise quiet mould and dynamic model, described dynamic model comprises the mold cavity plate, offers injection orifice on the mold cavity plate, injection orifice is connected with injection machine, is provided with the mold cools down plate between mold cavity plate and injection machine.
Above-mentioned Gao Guang, the molten trace injection-die of nothing are furnished with controller, and controller is connected with injection machine, heater and temperature sensor respectively by connecting line.
Above-mentioned heater and temperature sensor are arranged in the mold cavity plate.
Above-mentioned heater adopts electric heater.
Be provided with cooling water pipeline in the above-mentioned mold cools down plate.
Above-mentioned controller adopts Programmable Logic Controller, microcomputer or single-chip microcomputer.
Above-mentioned controller is furnished with touch-screen, display, keyboard, mouse.
The beneficial effects of the utility model are: because this injection mold is furnished with controller, Measurement die cavity plate temperature inside sends corresponding information according to variation of temperature to injection machine in real time, and assurance injection moulding function is injected plastic cement under suitable temperature; In the mould matched moulds, adopt coldplate to cool off, improved cooling effectiveness; The utility model can heat and cooling the mold cavity plate according to each stage of injection cycle, mold temperature control accuracy height, mold heated and cooling range are big, utilize this mould can obtain high surface brightness, weldless trace, need spray process, good product performance, plastic products that production cost is low.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
As shown in Figure 1, a kind of Gao Guang, there is not molten trace injection-die, comprise quiet mould 1 and dynamic model 2, described dynamic model 2 comprises mold cavity plate 3, be provided with electric heater 4 and temperature sensor 5 in the mold cavity plate 3, electric heater 4 is connected with controller 6 by connecting line with temperature sensor 5, the control mode that controller 6 can adopt temperature or time or temperature and time to control simultaneously, controller 6 adopts microcomputer, is furnished with display, keyboard, mouse, controller 6 is connected with injection machine 7 by connecting line, injection machine is connected with injection orifice on the mold cavity plate 3, between injection machine 7 and mold cavity plate 3, be provided with mold cools down plate 8, be provided with cooling water pipeline in the mold cools down plate 8, cooling water pipeline is connected with the water source, cooling water is circulated in cooling water pipeline, guarantee that mold cools down plate 8 has enough chilling temperatures, when 3 heating of mold cavity plate, mold cools down plate 8 is separated with mold cavity plate 3, when finishing matched moulds, during the injection machine start injection, mold cools down plate 8 contacts with mold cavity plate 3, and mould is cooled off.
In injection cycle, when mould was opened, controller received the die sinking signal of injection machine feedback, and controller provides signal, and heater begins the mold cavity plate is heated.When the mold cavity plate temperature met the requirements of scope, the temperature sensor in the mold cavity plate was passed to controller with temperature signal, and controller provides signal, and heater stops heating, sent the signal that can inject to injection machine simultaneously.Finish matched moulds, in the time of the start injection action, coldplate begins to play a role, and mould is cooled off.After the cooling action of mould reaches requirement, the lathe die sinking, and carry out next one circulation automatically.
Certainly, protection domain of the present utility model is not limited to the foregoing description, so long as those of ordinary skills, according to the utility model done without creatively improving, just should be within protection domain of the present utility model.
