Abstract
The invention provides a feeding unit for injection molding of an automobile. According to the feeding unit, an injection molding material is smelted and then is conveyed into an injection molding mould, wherein a feeding barrel of the feeding unit is provided with a transportation screw rod for transporting the injection molding material; a shaft of the transportation screw rod is internally provided with an electric heating part; the transportation screw rod can be used for rapidly transferring the injection molding material; the screw rod also has a heating function so that the production efficiency is further improved.
Description
Technical field
The present invention, about the injection unit in a kind of automobile adapted to injection system, particularly adapts to multi-purpose injection unit.
Background technology
Processing technology molded or casting can large batch of acquisition same size part, therefore it has important effect in processing and manufacturing field.Mould process technology has become one of important symbol of weighing a national product manufacture level.
This technique is by being used a kind of formation system to make moulding material (such as materials such as polyethylene terephthaldehyde ester (PET), polypropylene (PP)) make mechanograph.Moulding process (such as injection mo(u)lding) can be used for producing various mechanographs.
A typical adapted to injection system includes but not limited to a feeding unit, a locked mode assembly and a die assembly.Raw material (such as PET particle etc.) are fed in feeding unit successively by a hopper, and heater in barrel in this unit carrys out heat fused, to provide condition to follow-up injection moulding.
In automobile moulding processing, its moulding size is larger, therefore needs to keep the injected plastics material can be in a long time in molten condition, therefore its heat time longer, affect efficiency.Too high, the long heat time will affect the quality of this injected plastics material simultaneously, makes the physicochemical property of moulding change and lose efficacy.
Therefore need to provide a kind of automobile injection moulding feeding unit, guaranteeing that injected plastics material reaches under the condition of molten condition completely, shorten this period, guarantee production efficiency and product quality.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of automobile injection moulding feeding unit, it comprises: entrance, described entrance is connected with hopper, is granular injected plastics material to pack into; Feed cylinder, has heater so that described graininess injected plastics material is molten into molten condition in described feed cylinder; And outlet, described outlet is connected with injection molding unit, and described injection molding unit is by the injected plastics material input injection mould of described molten condition; Wherein: in described feed cylinder, there is the transportation screw rod of carrying described injected plastics material, and there is electric heating element in the axle of described transportation screw rod.
Passing through transportation screw rod in the present invention can be fast shifts injected plastics material, improve production efficiency, and this screw rod also has heating function, has further improved production efficiency.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
Reference numeral: 10 feeding units, 11 entrances, 12 hoppers, 13 granular injected plastics materials, 14 feed cylinders, 15 outlets, the injected plastics material of 16 molten conditions, 17 transportation screw rods, 18 electric heating elements, 19 axles, 20 helical blades, 21 ventholes, 22 heat-insulation layers.
The specific embodiment
As shown in Figure 1, the invention provides a kind of feeding unit 10 for automobile injection moulding, it comprises: entrance 11, and described entrance is connected with hopper 12, is granular injected plastics material 13 to pack into; Feed cylinder 14, has heater so that described graininess injected plastics material 13 is molten into molten condition in described feed cylinder 14; With outlet 15, described outlet 15 is connected with injection molding unit, and the injected plastics material of described molten condition 16 is inputted injection mould by described injection molding unit; Wherein: in described feed cylinder 14, there is the transportation screw rod 17 of carrying described injected plastics material, and there is electric heating element 18 in the axle 19 of described transportation screw rod 17.
Passing through transportation screw rod in the present invention can be fast shifts injected plastics material, improve production efficiency, and this screw rod also has heating function, has further improved production efficiency.
As one embodiment of the present of invention, described electric heating element 18 is arranged in the axle of described transportation screw rod and is connected with external heat power supply.When guaranteeing transportation, provide the heating of following, boost productivity.
As the improvement of this embodiment, described transportation screw rod 17 has helical blade 20, and described helical blade 20 promotes described injected plastics material.
As a preferred embodiment of the present embodiment, described injection moulding material is arranged between described helical blade 20 and the inwall of described feed cylinder 14, and is become molten by 20 extrusion shearings of described helical blade.Auxiliary shearing manipulation, has accelerated the conversion of the injected plastics material 16 of granular injected plastics material 13 phase molten conditions, and can keep the characteristic of its low temperature thus.
In the present embodiment, screw rod not only provides transportation and heating, simultaneously because injected plastics material is in an embodiment with the position relationship of helical blade and feed cylinder inwall, the shear extrusion power being provided by helical blade 20 has been provided, make injected plastics material also can be squeezed at low temperatures molten condition, improve productivity ratio, and kept the characteristic of its low temperature.
As another embodiment of the present invention, described feed cylinder 14 is being provided with venthole 21 near described outlet 15 places.Gas during for injected plastics material melting is discharged provides passage.
Further improve as of the present invention, the outer wall of described feed cylinder 14 has heat-insulation layer 22.Keep the temperature in whole operation stage.
The present invention can realize low temperature, molten injected plastics material is provided fast, has therefore accelerated efficiency, has guaranteed quality.
Should be appreciated that invention which is intended to be protected is not limited to non-limiting embodiments, should be appreciated that non-limiting embodiments describes as just example.The protection domain of the essence that the application will require is more embodied in the scope that independent claims provide, with and dependent claims.
