Abstract
The utility model discloses a drip-proof car injection-molding injection head. An upper-end inlet of the injection head is connected with an injection-molding system; injection-molding materials in a molten state are accommodated in the injection-molding system; the lower-end outlet of the injection head is connected with a mould of a car injection-molding piece; a one-way pressure valve is arranged at the upper-end inlet; high pressure is removed during injection-molding interval; the valve is closed to prevent the injection-molding materials from entering, and avoids invasion of phenomena such as dripping on the outside.
Description
Technical field
The utility model, about the head in a kind of automobile adapted to injection system, particularly has the head of drip-proof function.
Background technology
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.
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.
The 1st, 601, No. 419 BP (assignees: Warnke Umformtech; Publication date: on October 28th, 1981) disclosed have two moulds install a kind of mould in the injection molding machine of pressing plates closed with sealed layout.One in described pressing plate is guided on lathe, and can and open in direction and move with respect to another pressing plate at the closing direction of mould.Working cylinder/piston unit is used for making two moulds pressing plate gathering is installed and separates.Use lock uint, it causes that two moulds installation pressing plates are clamped together in closing position.Also disclose a kind of equipment for generation of closing force and clamping force.
In this process, distinguish conventional metals 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 when injection moulding high-quality automobile component, because the mobility of melted material is too high, therefore the head in adapted to injection system easily produces water clock, cause the pollution to injection machine, injection mold etc., this water clock also makes the shot of next injection cycle to ensure simultaneously, more can produce defect to the surface of moulding because of water clock.
Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of antidrip automobile injection moulding head, the upper end entrance of described head is connected with adapted to injection system, in described adapted to injection system, accommodate the injected plastics material that is molten state, and the outlet of the lower end of described head is connected with the mould of automobile moulding, wherein: be provided with one-way pressure valve in porch, described upper end.
One-way pressure valve in the normal injection moulding process of high temperature, high pressure, melted material can by and be injected, remove high pressure in injection moulding gap, its valve closing, prevents entering of injected plastics material, avoids the infringement to external world of the phenomenons such as water clock.
Brief description of the drawings
Fig. 1 is the utility model schematic diagram;
Fig. 2 is the utility model electrical connection schematic diagram.
Reference numeral: 10 heads, 11 adapted to injection system, 12 injected plastics materials, 13 moulds, 14 one-way pressure valves, 15 pressure sensors, 16 calculate control assembly, 17 cavitys, 18 primary outlets, 19 sub-outlets.
Detailed description of the invention
As shown in Figure 1, the utility model provides a kind of antidrip automobile injection moulding head 10, the upper end entrance of described head 10 is connected with adapted to injection system 11, in described adapted to injection system, accommodate the injected plastics material 12 that is molten state, and the outlet of the lower end of described head 10 is connected with the mould 13 of automobile moulding, wherein: be provided with one-way pressure valve 14 in porch, described upper end.
The utility model is in normal injection moulding process, because injected plastics material 12 has been applied in high temperature, high pressure, therefore one-way pressure valve 14 is opened under high temperature, high pressure, with make injected plastics material 12 can by and be injected, remove high pressure in injection moulding gap, injected plastics material 14 loses the effect of high pressure, and its one-way pressure valve 14 is closed, prevent entering of injected plastics material 12, avoid the infringement to external world of the phenomenons such as water clock.
As an embodiment of the present utility model, on this head, also there is the pressure sensor 15 connected with described one-way pressure valve, to control the opening and closing of described one-way pressure valve 14.This sensor has ensured the temperature and pressure setting of valve opening.
As the further improvement of above-described embodiment, be also connected with and calculate control assembly 16 at described pressure sensor 15.Be associated by calculating the parts such as control assembly 16 and injection machine, realize the automation in Shooting Technique, and ensure that mould can not be injection molding in the time of unlatching.
As another embodiment of the present utility model, the lower end of described head 10 is cavity 17, and the outlet of described lower end is positioned at the top of described cavity 17.Cavity reclaims the injected plastics material in injection moulding gap 12, prevents that it is by water clock.
As another improvement of this embodiment, in the utility model, head 10 is in the short transverse along described cavity 17, and the outlet of described lower end comprises primary outlet 18 and sub-outlet 19.The primary outlet 18 of higher position is born normal Shooting Technique, helps prevent the generation of water clock compared with the sub-outlet of low side 19.Wherein preferred, the size of described primary outlet 18 is greater than the size of described sub-outlet 19
The utility model can be realized automation control, coordinates the work of each adapted to injection system, prevents the generation of water clock, also avoids less water clock to cause the loss in mould simultaneously.Its structure has also ensured the discharge rate minimum of water clock simultaneously.
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.
