Abstract

The utility model discloses a kind of hot flow path hot mouths, are fixed between die shunting plate and type chamber, including hot mouth main body and thermally conductive copper sheathing;Hot mouth main body runner is provided in hot mouth main body, thermally conductive copper sheathing is fixed on hot mouth body exterior.The utility model hot mouth, in the heat transfer to hot mouth main body of flow distribution plate, to realize that hot mouth can reach the temperature by the plastics of melting from flow distribution plate injection type chamber without heating coil, gets rid of hot mouth because the condition of heating coil fetters by thermally conductive copper sheathing.Realize that hot mouth especially length is less than the short hot mouth of 40mm and more effectively widely uses.

Description

A kind of hot flow path hot mouth
Technical field
The utility model relates to hot runner mould technical field, especially a kind of hot flow path hot mouth.
Background technique
With the development of injection molding technology, Hot runner Technology more widely applies in injection mold.Hot mouth is heat Important component in flow passage system.Hot mouth commonly used in the prior art is cased with heatable heating coil, can generally fill outside heating coil Upper hot mouth protective case.But due to the power limit of heating coil, hot mouth length generally can not be less than 40mm.If required hot mouth is shorter than 40mm, since the limitation of heating coil power has to lengthen hot mouth.The length of hot mouth is directly proportional with mold thickness, increases mold Thickness will lead to other wastings of resources for increasing the unnecessary production cost of mold and matching.
Summary of the invention
The utility model aim be for overcome the deficiencies in the prior art and provide one kind be not required to set heating coil and be not required to by The hot mouth of heating coil power limit.To achieve the above object, the utility model uses following technical scheme:
The utility model discloses a kind of hot flow path hot mouths, are fixed between die shunting plate and type chamber;Including hot mouth Main body and thermally conductive copper sheathing, the thermally conductive copper sheathing are fixed on hot mouth body exterior.
Further, the hot flow path hot mouth further includes spreader and sealing ring;The sealing ring fixes spreader In hot mouth main body, it is provided with hot mouth main body runner in the hot mouth main body, spreader runner, institute are provided in the spreader Hot mouth main body runner is stated to be connected to spreader runner.
Further, the thermally conductive copper sheathing and hot mouth main body are interference fitted.
Further, the conduction copper is applied lock screw and is fixed in hot mouth main body.
Preferably, the hot mouth principal length is less than 40mm.
Due to the application of the above technical scheme, the utility model has the advantage that compared with prior art
The utility model by thermally conductive copper sheathing in the heat transfer to hot mouth main body of flow distribution plate, to realize that hot mouth does not have to Heating coil can reach the temperature by the plastics of melting from flow distribution plate injection type chamber, get rid of condition beam of the hot mouth because of heating coil power It ties up.Realize that the especially short hot mouth of hot mouth is more effective and widely uses.

Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation Example, the present invention will be further described in detail.
Embodiment one
As shown in Figure 1, the hot flow path hot mouth 2 of the present embodiment is applied to sprue system.Hot flow path hot mouth 2 is matched by screw thread Conjunction, which is fixed on flow distribution plate 1, to be placed in type chamber 3.As shown in Fig. 2, hot flow path hot mouth 2 includes hot mouth main body 22 and thermally conductive copper sheathing 21. Thermally conductive copper sheathing 21 is placed in hot mouth main body 22 using interference fit, and thermally conductive copper sheathing 21 is fixed on hot mouth master with lock screw 25 On body 22.Hot mouth principal length is less than 40mm.Hot flow path hot mouth 2 is directly by thermally conductive copper sheathing 21 the heat transfer of flow distribution plate 1 Onto hot mouth main body 22, to realize that hot mouth does not have to heating coil and can reach the plastics of melting from 1 injection type chamber 3 of flow distribution plate Temperature gets rid of hot mouth because the condition of heating coil power fetters.
Embodiment two
As shown in figure 3, the hot flow path hot mouth 2 of the present embodiment is applied to hole irrigation port system.Hot flow path hot mouth 2 is matched by screw thread Conjunction, which is fixed on flow distribution plate 1, to be placed in type chamber 3.As shown in figure 4, hot flow path hot mouth 2 includes hot mouth main body 22, spreader 23, envelope Rubber ring 24 and thermally conductive copper sheathing 21.Spreader 23 is fixed in hot mouth main body 22 by sealing ring 24.Heat is provided in hot mouth main body 22 Mouth main body runner 26 is provided with spreader runner 27 in spreader 23, and hot mouth main body runner 26 is connected to spreader runner 27.It leads Hot copper sheathing 21 is placed in hot mouth main body 22 using interference fit, and thermally conductive copper sheathing 21 is fixed on hot mouth main body with lock screw 25 On 22.Hot mouth principal length is less than 40mm.Hot flow path hot mouth 2 directly arrives the heat transfer of flow distribution plate 1 by thermally conductive copper sheathing 21 In hot mouth main body 22, to realize that hot mouth can reach the temperature by the plastics of melting from 1 injection type chamber 3 of flow distribution plate without heating coil Degree gets rid of hot mouth because the condition of heating coil power fetters.
In conclusion the utility model structure is simple, it is suitable for popularization and application.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not It is confined to this, anyone skilled in the art within the technical scope disclosed by the utility model, can readily occur in Change or replacement, should be covered within the scope of the utility model.
