Part of the body and the cylinder is formed, and the passageway is had a perfect understanding to its inside being equipped with, and the one end that has a perfect understanding the passageway is equipped with the bell that matees with the screw head shape of screw rod assembly, and the nozzle grafting is equipped with on the lateral wall of cylinder and has a perfect understanding the exhaust hole that the passageway feeds through in being fixed in the other end that has a perfect understanding the passageway. The utility model discloses a structural exhaust hole that is equipped with of flange, meeting from exhaust hole discharge before the tail gas entering nozzle, the interior tail gas of plastics liquid that enters into in the nozzle obtains basic discharge, has improved the quality of moulding plastics effectively, the structural bell that sets up of flange can cooperate with the screw head better, and the plastics liquid flow is more smooth and easy.
Description
Technical field
The utility model relates to injection machine technical field, is specifically related to a kind of flange arrangement being applied to injecting machine material tube.
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 plastic raw materials 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.Real work shows, the gas produced can only drain major part by the exhaust outlet be located on barrel body, remaining tail gas can be followed plastic raw materials and be entered in nozzle by screw head, and this small amount of tail gas can produce comparatively significantly harmful effect to injection moulding quality.Can not solve the technical scheme of this technical problem at present.
Utility model content
In order to solve above technical problem, the utility model provides a kind of flange arrangement being applied to injecting machine material tube, and the tail gas of emptying non-in barrel can be carried out emptying by it, thus improves injection moulding quality.
The utility model is achieved through the following technical solutions:
A kind of flange arrangement being applied to injecting machine material tube, described injecting machine material tube also comprises cylindrical shell, screw rod assembly and nozzle outside described flange arrangement, screw rod assembly is located in cylindrical shell, cylindrical shell is connected with nozzle by flange arrangement, described flange arrangement is the T-shaped body be made up of disc and cylinder, its inside is provided with through channel, one end of through channel is provided with the bell with the screw head form fit of screw rod assembly, nozzle grafting is fixed in the other end of through channel, and the sidewall of cylinder is provided with the steam vent be communicated with through channel.
As preferred embodiment, the diameter of described steam vent is for being not more than 4mm.
As preferred embodiment, described disc is evenly equipped with screw, flange arrangement is fixed on the end of cylindrical shell by the screw through screw.
As preferred embodiment, described steam vent is located at the position, side of the nozzle bottom after grafting.
The beneficial effects of the utility model are: flange arrangement of the present utility model is provided with steam vent, and can discharge from steam vent before tail gas enters nozzle, the plastic liquid inner exhaust gas entered in nozzle is discharged substantially, effectively improves injection moulding quality; Bell set on flange arrangement can coordinate with screw head better, and plastic liquid flowing is more smooth and easy.
Accompanying drawing explanation
Fig. 1 is the overall structure figure that the utility model is applied to barrel;
Fig. 2 is the profile of the utility model flange arrangement;
Fig. 3 is the side view of the utility model flange arrangement.
Symbol description: 1-flange arrangement, 2-cylindrical shell, 3-screw rod assembly, 4-nozzle, 11-disc, 12-cylinder, 13-through channel, 14-bell, 15-steam vent, 16-screw.
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, the injecting machine material tube that flange arrangement of the present utility model is applied, except flange arrangement 1, also comprises cylindrical shell 2, screw rod assembly 3 and nozzle 4, and screw rod assembly 3 is located in cylindrical shell 2, and cylindrical shell 2 is connected with nozzle 4 by flange arrangement 1.Screw rod assembly 3 is for carrying out compression plasticizing, pushing to the plastic raw materials entering barrel.During specific works, plastic raw materials enters in cylindrical shell 2 by feeding device, and under the rotary compression effect of screw rod assembly 3, plastic raw materials can become the melt of molten.Melt can be followed screw rod assembly 3 and be pushed ahead, and is ejected after the steps such as exhaust, further compression by nozzle 4.
With reference to Fig. 2, flange arrangement 1 of the present utility model is the T-shaped body be made up of disc 11 and cylinder 12, its inside is provided with through channel 13, one end of through channel 13 is provided with the bell 14 with the screw head form fit of screw rod assembly 3, nozzle 4 grafting is fixed in the other end of through channel 13, and the sidewall of cylinder 12 is provided with the steam vent 15 be communicated with through channel 13.Steam vent 15 is preferably located at the position, side bottom the nozzle 4 after grafting.
Molten plastic enters in through channel 13 after screw head extrudes, then enters into the ejection of nozzle 4 inner high voltage further.When through through channel 13, tail gas contained in molten plastic can be discharged from steam vent 15, makes the molten plastic entered in nozzle 4 substantially not contain gas, thus effectively improves injection moulding quality.During concrete enforcement, the diameter of steam vent 15 should be not more than 4mm, avoids molten plastic to emerge from steam vent 15.
With reference to Fig. 3, the disc 11 of the utility model flange arrangement 1 is evenly equipped with screw 16, during concrete installation, flange arrangement 1 is by being fixed on the end of cylindrical shell 2 through the screw of screw 16.This mounting structure is reliable and stable, and sealing is good.
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.
