Abstract
The utility model relates to a multipurpose automotive injection-molding jetting unit. The jetting unit is internally provided with molten-state injection materials, wherein the injection materials enter an injection mold through a jetting hole of the jetting unit. The jetting unit comprises a bottom end and a body, wherein the body is located at the upper part of the bottom end, and the bottom end is provided with a cone-shaped solid head; the body is a cavity for containing the injection materials. By utilizing the solid head at the bottom end, the pressure and the temperature are balanced, and the jetting unit is protected.
Description
Technical field
The utility model, about the injection unit in a kind of automobile adapted to injection system, particularly adapts to multi-purpose injection unit.
Background technology
Moulding process 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.
Processing technology molded or casting can large batch of acquisition same size part, so 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.
A typical adapted to injection system includes but not limited to an injection molding unit, a locked mode assembly and a die assembly.Injection molding unit can be reciprocating screw type, or two-stage screw type.In reciprocating screw type injection molding unit, raw material (such as PET particle etc.) are fed to the arrival end of plasticized screw successively by a hopper.Plasticized screw is enclosed within a barrel, by material tube heater, carrys out heating cylinder.
In automobile moulding processing, its moulding size is larger, therefore need to keep the injected plastics material can be in a long time in molten condition, and in addition, automobile component material therefor is varied, and its injection temperature and pressure are also different.
In this process, distinguish traditional metal casting, its nozzle and mould are all exerted pressure, and tonnage can be changed to 6000 tons of per inch from being less than five tons.
Under high pressure, high temperature, melted material is an impact to injection unit, is the process as injection cycle simultaneously, and this injection unit also answers within a short period of time cooling, to avoid injected plastics material to outflow during injection moulding gap.
So the alternating action of injection unit in cold and hot temperature, high-low pressure, it easily produces and destroys, and when this injection unit is applied to various injected plastics materials and part dimension, its requirement to temperature, pressure is higher.
Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of multipurpose automobile injection moulding injection unit, in described injection unit, hold the injected plastics material that is molten state, described injected plastics material enters in injection mould through the loophole of described injection unit, and wherein: described injection unit comprises: bottom and the body that is positioned at top, described bottom, and described bottom is cone shape solid head, described body is cavity and holds described injected plastics material position in the inner.
The solid head of the bottom in the utility model not only balance the effect of pressure, can provide effective heat radiation to the cataclysm of temperature especially, guarantee that the overall structure of injection unit is not damaged.This injection unit will be suitable for multiple injected plastics material and Shooting Technique condition.
Accompanying drawing explanation
Fig. 1 is the utility model schematic diagram.
Reference numeral: 10 injection units, 11 outer walls, 12 primary outlets, 13 sub-outlets, 14 injected plastics materials, 15 injection moulds, 16 bottoms, 17 bodies, 18 electrical heating conductors, 19 cooling-parts.
The specific embodiment
As shown in Figure 1, the utility model provides a kind of multipurpose automobile injection moulding injection unit 10, in described injection unit 10, hold the injected plastics material 14 that is molten state, described injected plastics material enters in injection mould 15 through the loophole of described injection unit, and wherein: described injection unit 10 comprises: bottom 16 and the body 17 that is positioned at top, described bottom, and as shown in the figure, described bottom 16 is cone shape solid head, described body 17 is for cavity and hold 14 of described injected plastics materials in the inner.
The solid head of the bottom in the utility model not only balance the effect of pressure, can provide effective heat radiation to the cataclysm of temperature especially, guarantee that the overall structure of injection unit is not damaged.This injection unit will be suitable for multiple injected plastics material and Shooting Technique condition.
Simultaneously body 17 is positioned at described in it on bottom 16, and its inner injected plastics material 14 has obtained reasonable adjustment and balance, prevents its infringement to injection unit integral body.
As an embodiment of the present utility model, described solid head is electrical heating conductor 18 and is connected with external heat power supply.This solid head has characteristic of electric heating element, therefore during opposing injection moulding gap, and with protecting injection unit during cooling-part contact in mould.
As another embodiment of the present utility model, the upper end of described cavity is furnished with cooling-part 19.As preferably, described cooling-part 19 is for connecting the conduit of cooling agent.This position is provided with cooling-part, and it can resist the high temperature from injected plastics material, protection injection unit.
As another embodiment of the present utility model, on the outer wall 11 of described cavity, there is primary outlet 12 and sub-outlet 13, and in the short transverse along described cavity, described primary outlet 12 is higher than described sub-outlet 13.
As the preferred version of this embodiment, the size of described primary outlet 12 is greater than the size of described sub-outlet 13.
The utility model can be realized the bidirectional modulation to high low temperature, high-low pressure, protection injection unit, and go for multiple injected plastics material and Shooting Technique condition.
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.
