This is distinguished.For example, first runner can be referred to as second flow channel, equally, second flow channel can also be referred to as first runner, this
Without departing from the protection scope of this application.
As depicted in figs. 1 and 2, one embodiment of the invention provides a kind of hot runner system, which includes hot mouth
Component 10, temperature control box and at least formed on the hot flow path in hot mouth component 10, pass through the hand to injecting glue material heating and temperature control
Section, the plastics of molten condition is successively poured into after hot mouth component 10 in the type chamber of mold, avoids the shape of gating system of material
At.
Hot mouth component 10 include longitudinally 11 extend hot mouth 12, needle 14 and be all connected to sharp-tongued the 16 of hot mouth 12
With sprue bush 18, and on the circumferential direction perpendicular to longitudinal axis 11, portion gate set 18 is between hot mouth 12 and sharp-tongued 16.Separately
Outside, the first runner 22 of the sharp-tongued 16 sharp-tongued ontologies 20 extended including longitudinally 11 and composition part hot flow path, 14 edge of needle
Longitudinal axis 11 is movably disposed in inside sharp-tongued ontology 20.Hot mouth 12 has the second flow channel 24 being connected with first runner 22,
Sprue bush 18 is equipped with the cast gate 26 being connected with first runner 22, and needle 14 can drivingly longitudinally 11 be moved to open
Or cast gate 26 is closed, to be poured or stop being poured.
Further, sprue bush 18 has the table top 28 being at an angle of with longitudinal axis 11, and sharp-tongued ontology 20 has and table top 28
The end face 30 to fit, table top 28 is spaced apart on the extending direction of longitudinal axis 11 with cast gate 26, and sharp-tongued ontology 20
Needle 14 is upwardly away from the week perpendicular to longitudinal axis 11.
In this preferred embodiment, since sprue bush 18 has the table top 28 being at an angle of with longitudinal axis 11, table top 28 and cast gate
26 is spaced apart on the extending direction of longitudinal axis 11, and sharp-tongued ontology 20 is upwardly away from the week perpendicular to longitudinal axis 11
Needle 14.Therefore, sprue bush 18 is oriented to needle 14 and is carried out sealing, so that the diameter of sprue bush 18 is smaller, to make
Hot mouth component 10 it is compact-sized, save space.And the end face 30 of sharp-tongued ontology 20 and the table top 28 of sprue bush 18 fit, platform
Face 28 is spaced apart on the extending direction of longitudinal axis 11 with cast gate 26, that is to say, that sharp-tongued ontology 20 and sprue bush 18
Bonding position far from cast gate 26 so that can effectively avoid hiding glue, be highly convenient for colour changing mold.
Furthermore 18 front-end architecture of sprue bush is stablized, it is suitable for more products convenient for product with type.Further, it enables cast gate

Degree.Sharp-tongued ontology 20 includes the upper end 32 being connected with hot mouth 12 and the lower end 34 being connected with upper end 32, lower end
34 is parallel with longitudinal axis 11, that is to say, that lower end 34 is vertically extending along the direction parallel with longitudinal axis 11, and end face 30
It is formed in the end of lower end 34.On the circumferential direction perpendicular to longitudinal axis 11, the part lower end 34 of neighbouring upper end 32 with pour
Muzzle 18 fits, and has certain interval between another part lower end 34 and sprue bush 18 far from upper end 32.
In general, sharp-tongued 16 metal materials good using thermal conductivity, so that 26 temperature of cast gate is stablized.Preferably, sharp-tongued 16
Material is set as copper.Certainly, sharp-tongued 16 material that other thermal conductivity can also be used good.
Sprue bush 18 includes upper mating part 36 between hot mouth 12 and sharp-tongued 16, from upper mating part 36 to close to the longitudinal axis
The company of extension 38, the gate part 40 and connection extension 38 and gate part 40 that define cast gate 26 that the direction of line 11 extends
Socket part 42, extension 38 define table top 28.The angled setting of interconnecting piece 42 and gate part 40, specifically, interconnecting piece 42 with pour
Formed angle is obtuse angle between oral area 40.
Sprue bush 18 further includes the protruding portion that the periphery of upper mating part 36 is protruded from the circumferential direction perpendicular to longitudinal axis 11
44, the plane that definition extends through longitudinal axis 11 is the first plane, and the projection of table top 28 on the first plane is located at protruding portion 44
In drop shadow spread on the first plane, it is, table top 28 is located at protruding portion in the short transverse for being parallel to longitudinal axis 11
In 44 altitude range.
Preferably, it uses and is threadedly coupled between sprue bush 18 and hot mouth 12.Specifically, the upper mating part 36 of sprue bush 18 with
Using threaded connection between hot mouth 12.Certainly, other connection types can also be used between sprue bush 18 and hot mouth 12.
It should be appreciated that although this specification is described in terms of embodiments, but not each embodiment only includes one
A independent technical solution, this description of the specification is merely for the sake of clarity, and those skilled in the art should will say
As a whole, the technical solution in each embodiment may also be suitably combined to form those skilled in the art can for bright book
With the other embodiments of understanding.
The series of detailed descriptions listed above only for feasible embodiment of the invention specifically
