Description
Technical field
The utility model relates to injection machine technical field, is specifically related to a kind of barrel being applied to injection machine.
Background technology
Screw injection molding machine is the most widely used current a kind of injection molding machine product.Screw injection molding machine operationally, generally first granular or powdered plastic are joined in barrel, plastics are made to become molten condition by the rotation of barrel inner screw and the heating of barrel, then plastics forward is ordered about by the rotation of screw rod, plastics are penetrated from nozzle with very high pressure and speed, being injected in close die, is required moulded plastic products through pressurize, cooling Post RDBMS.
When barrel is processed raw material by screw rod rotation, can through the process of a pressurization, decompression, in the process, moisture in plastic raw materials after melting and volatile materials can gasify, following plastic raw materials injection in order to avoid the moisture after gasification and volatile materials is injected in product, and the moisture after these gasifications and volatile materials can be discharged by exhaust outlet.
Only in the stage casing of barrel, the position of corresponding screw rod releasing section is provided with exhaust outlet to traditional barrel, the steam that the plastic grain entering barrel comprises needs to discharge from exhaust outlet behind compression section, when the moisture content contained by plastic grain is larger, harmful effect can be produced to the compression melting process of plastic grain, in addition, these relatively large steam are also difficult to a guarantee emptying through exhaust outlet, and the tail gas retained can produce harmful effect to last injection moulding quality.
Utility model content
In order to solve above technical problem, the utility model provides a kind of barrel being applied to injection machine, and it can be vented first when plastic grain enters, and the overall exhaust capacity of barrel gets a promotion, and effectively improves the injection moulding quality of injection machine.
The utility model is achieved through the following technical solutions:
A kind of barrel being applied to injection machine, screw rod assembly is installed in described barrel, described screw rod assembly is respectively equipped with feed zone, compression section, releasing section and transition from top to end, the position of the corresponding feed zone of barrel is provided with charging aperture, and the sidewall that barrel is relative with charging aperture is provided with the steam vent formed by kerve.
As preferred embodiment, the sidewall of the corresponding feed zone of described barrel is evenly equipped with triangle groove.
As preferred embodiment, on a described steam vent triangle groove located therein.
As preferred embodiment, the end rounding off of described triangle groove is on barrel sidewall.
As preferred embodiment, the quantity of described steam vent is three or more, and steam vent is arranged side by side along the axis of barrel.
As preferred embodiment, the diameter of described steam vent is not more than 3mm.
The beneficial effects of the utility model are: barrel of the present utility model is provided with steam vent at charging aperture place, the steam that steam vent can produce before not plastifying the plastic grain entering barrel is exhausted process, the water content of effective reduction plastic grain, the compression plasticizing quality of plastic grain is better; The exhaust outlet that steam vent coordinates rear end to arrange can improve the overall exhaust capacity of barrel, thus effectively improves the injection moulding quality of injection machine; Steam vent is obtained by kerve process, and processing is simple, guarantees that the overall tightness of barrel is substantially unaffected.Especially, when barrel sidewall being distributed with triangle groove, effectively can increase frictional force between material and barrel, make charging swifter and more violent, the stability of charging also improves, further when steam vent is distributed on triangle groove, the air inlet area of steam vent can be made to increase, thus increase tail part exhaust amount.

Symbol description: 1-barrel, 2-screw rod assembly, 3-charging aperture, 4-steam vent, 5-exhaust outlet, 6-triangle groove.
Detailed description of the invention
With reference to the accompanying drawings and the utility model will be further described in conjunction with the embodiments.
As shown in Figure 1, be provided with screw rod assembly 2 in barrel 1 of the present utility model, screw rod assembly 2 is respectively equipped with feed zone, compression section, releasing section and transition from top to end, and the position of the corresponding feed zone of barrel 1 is provided with charging aperture 3.During specific works, plastic grain enters in barrel 1 by feeding device through charging aperture 3, and under the rotary compression effect of screw rod, plastic grain can become the melt of molten.Melt can be followed screw rod and be pushed ahead, and ejects after the steps such as exhaust, further compression.
As depicted in figs. 1 and 2, the steam produced before not plastifying to make plastic grain can be discharged in time, and the utility model is provided with the steam vent 4 formed by kerve on the sidewall that barrel 1 is relative with charging aperture 3.This steam vent 4 makes barrel 1 inside be communicated with outside atmosphere, when barrel 1 carries out reinforced, the steam part that plastic grain produces directly is discharged from steam vent 4, therefore follows the water content that plastic grain carries out compressing plasticizing and greatly reduces, thus make the compression plasticizing quality of plastic grain better.
In addition, similar to traditional barrel 1 structure, the position of the corresponding releasing section of barrel 1 is provided with exhaust outlet 5.This exhaust outlet 5 and aforesaid steam vent 4 cooperating can improve the overall exhaust capacity of barrel 1, thus effectively improve the injection moulding quality of injection machine.
During concrete enforcement, have required exhaust effect in order to ensure steam vent 4, the quantity of steam vent 4 is preferably set to three or more, and is arranged side by side along the axis of barrel 1.In addition, in order to avoid plastic grain is emerged from steam vent 4, the diameter of steam vent 4 should be set to and be not more than 3mm.
With reference to the structure chart of the another kind of embodiment of Fig. 3, the sidewall of the corresponding feed zone of barrel 1 in the present embodiment is evenly equipped with triangle groove 6.As shown in Figure 4, the degree of depth of this triangle groove 6 is generally set to about 1mm, and width is generally about 2mm.The density of triangle groove 6 can be arranged as required.After being provided with this triangle groove 6, effectively can increasing frictional force between material and barrel, make charging swifter and more violent, the stability of charging also improves, further when steam vent 4 is distributed on triangle groove, the air inlet area of steam vent 4 can be made to increase, thus increase tail part exhaust amount.In order to prevent material from gathering in the end of triangle groove 6, the end of triangle groove 6 is preferably set to rounding off on barrel sidewall.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
