Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a 3D prints hot runner flow distribution plate, includes flow distribution plate 1, and flow distribution plate 1 comprises last casing 2 and lower casing 3, just is located and has offered recess 7 between casing 2 and the lower casing 3 in the flow distribution plate 1, is provided with runner 5 in the recess 7, the exit position fixed mounting that the lower extreme of flow distribution plate 1 just is located runner 5's both ends bottom has heat to chew 4, and the upper end surface of going up casing 2 has seted up hot groove 6, and hot groove 6 has been seted up to the lower extreme surface of lower casing 3, is convenient for install the heating tube through setting up hot groove 6, and can reduce the volume of metal through setting up hot groove 6 to make heating time shorter, and the heating tube of installation, through reducing its power in order to reach energy-conserving effect.

In this embodiment, a hot nozzle hole 9 is respectively formed at four corners of the flow distribution plate 1 in a penetrating manner, the hot nozzle hole 9 penetrates through the four corners of the upper casing 2 and the lower casing 3 of the flow distribution plate 1, and the whole flow distribution plate 1 is fixedly connected by installing a fixing bolt in the hot nozzle hole 9 at the four corners of the upper casing 2 and the lower casing 3.

Meanwhile, the shape of the flow channel 5 is not limited, the flow distribution plate 1 is manufactured by adopting 3D printing integrated forming, and the volume of the flow distribution plate integrally formed by a 3D printer is smaller.

Further, the heat is chewed 4 inside and is provided with heat and chew runner 8, and heat is chewed runner 8 and is adopted the tee bend reposition of redundant personnel structure, and heat is chewed 4 and is adopted the integrated into one piece structure, and the velocity of flow of runner is chewed to the tee bend heat of this structure is faster, has improved circulation rate.

When the flow distribution plate is used, a person skilled in the art can use the flow distribution plate with the structure through a conventional use method, when fluid is distributed and conveyed through the flow distribution plate, compared with the traditional flow distribution plate, the flow distribution plate integrally formed through a 3D printer is smaller in size, the shape of a flow channel of the integrally formed flow distribution plate is not limited, the traditional flow channel is made of a round shape and is drilled by a deep hole drill, the traditional flow channel bears an angle of 90 degrees at a turning position, the fluid circulation is not facilitated, one end of the traditional flow channel needs to be sealed by a plug, the structure is increased, the plug is easy to damage, the situation of glue leakage is caused, meanwhile, the balance mode of the traditional flow channel is complex, the flow shear rate is generally completed in a layered mode, the total length of the flow channel is longer, the injection pressure is increased, the flow channel balance of the structure is simple and direct, and the flow distribution efficiency is high and the cutting efficiency is low, pressure consumption is little, the heat of conveying flow distribution plate simultaneously is chewed and is being carried the advection, owing to receive the restriction that the structure was chewed to heat, carry slowly, consequently, the heat on current flow distribution plate is chewed and is adopted tee bend shunting structure, it is faster to make the fluid pass through the velocity of flow that hot chews, the circulation rate has been improved, and chew through 3D printing integrated into one piece's heat, can print the interior runner that the heat of different structures was chewed according to actual demand, thereby avoided making new mould, could make new heat and chew, and then material saving and resource.
