Abstract
The utility model relates to a high-precision-dosage injection head for injection molding of an automobile. The injection head contains an injection molding material in a molten state, and an outlet is formed in the injection head and is connected with a mold for an automobile injection molding piece. The outlet is formed in the outer wall of the conical injection head, and the molten material is not directly injected from the lower end under high temperature and high pressure conditions, so that deformation is avoided, and the injection molding process is improved.
Description
Technical field
The utility model, about the head in a kind of automobile adapted to injection system, particularly has the high precisely head of dosage function.
Background technology
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.
The development of developing same molding process of auto industry is inseparable, and due to the parts of the large batch of manufacture same size of auto industry needs, so it relies on larger to molding process.In the parts of automobile, use in a large number at present mouldings, particularly inner-decoration component.
American industry circle is thought: mould is the foundation stone of American industry.Japanese industry circle is thought: mould is the power that promotes social prosperity.Mould is likened to " golden key golden key ", " entering the motive power of affluent society " abroad.
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, during injection moulding high-quality automobile component, adapted to injection system (comprising head) is easily out of shape, and causes the incorrect calculating to shot.Therefore need to provide high-precision shot to guarantee not to be subject to the intervention of high temperature, high pressure, produce the parts that can directly use.
As will be that to control last of accurate dosage articles injection-moulded near the nearest head of mould.Therefore need to provide a kind of head of high accurate dosage.
Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of automobile injection moulding high precisely dosage head, in described head, accommodate the injected plastics material that is molten state, and there is outlet on described head, described outlet is connected with the mould of automobile moulding, wherein: described head is conical, and described outlet is positioned on the outer wall of described conical head.
The outlet of the head in the utility model is positioned on outer wall, therefore its melted material under high temperature, high pressure will directly not injected from lower end, avoid the distortion that the impact of head is caused, can keep the shape of head, realize the accurate Calculation of shot, improve Shooting Technique.
Accompanying drawing explanation
Fig. 1 is the utility model schematic diagram.
Reference numeral: 10 heads, 11 outer walls, 12 primary outlets, 13 sub-outlets.
The specific embodiment
As shown in Figure 1, the utility model provides a kind of automobile injection moulding high precisely dosage head 10, in described head 10, accommodate the injected plastics material that is molten state, and there is outlet on described head 10, described outlet is connected with the mould of automobile moulding, wherein: described head 10 is conical, and described outlet is positioned on the outer wall 11 of described conical head.
The outlet of the head in the utility model is positioned on outer wall, is different from the design that prior art middle outlet is positioned at least significant end.Therefore its under high temperature, high pressure, (as the direction of arrow in Fig. 1) melted material will be directly from lower end injection, avoid distortion that the impact of head is caused, can keep the shape of head, realize the accurate Calculation of shot, improve Shooting Technique.
As improvement of the present utility model, in the short transverse along described head 10, described outlet comprises primary outlet 12 and sub-outlet 13.Guarantee that injected plastics material is injected from two class outlets.High temperature, the impact of high-pressure injection moulding material to head have been prevented.
As of the present utility model another, improve, the size of described primary outlet 12 is greater than the size of described sub-outlet 13.By the primary outlet 12 being positioned near head upper end, penetrate more material, simultaneously because head is pyramid type, its upper end is more prone to resist high pressure-temperature.Guarantee the consistency of head, improved accurate injection moulding dosage.
As an embodiment of the present utility model, the cross section of described primary outlet 12 is oval or circular.
As another embodiment of the present utility model, the cross section of described lower sub-outlet 13 is circular.
Optimal way as above-described embodiment.Described primary outlet 12 comprise a plurality of and at the sustained height of described head 10 around distribution.
The utility model has been avoided the sex change of head, improves its accurate injection moulding dosage, has avoided the impact of the HTHP of the direction of arrow in diagram.
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.
