Specific embodiment
Below with reference to specific embodiment shown in the drawings, the present invention will be described in detail.But these embodiments are simultaneously
The present invention is not limited, structure that those skilled in the art are made according to these embodiments, method or functionally
Transformation is included within the scope of protection of the present invention.
In each diagram of the application, for the ease of illustration, structure or partial certain sizes can be relative to other knots
Structure or part are exaggerated, and therefore, are only used for the basic structure of the theme of diagram the application.
Furthermore, it should be appreciated that although term first, second etc. can be used to describe herein various elements or
Structure, but these be described object should not be by the limitation of above-mentioned term.Above-mentioned term be only used for by these description objects that
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 shown in Figure 1, Figure 2 and Figure 3, one embodiment of the invention provides a kind of hot runner system, which includes
Mold and hot mouth component 10, mold define out frame 12, and hot mouth component 10, which is located at, to be opened in frame 12.Hot runner system further includes temperature control
Case and at least formed on the hot flow path in hot mouth component, by the means to injecting glue material heating and temperature control, by molten condition
Plastics be successively poured into after hot mouth component in the type chamber of mold, avoid the formation of gating system of material.
Hot mouth component 10 includes hot mouth 14, needle (not shown) and the mouth for being connected to hot mouth 14 of longitudinally 16 extensions
Point 15, sharp-tongued 15 includes the first runner 20 of the longitudinally 16 sharp-tongued ontologies 18 extended and composition part hot flow path, needle edge
Longitudinal axis 16 is movably disposed in inside hot mouth 14 and sharp-tongued ontology 18, and sharp-tongued 15 lower end is equipped with the opening of outflow injecting glue material
19。
Specific in the present embodiment, hot mouth 14 includes lower section hot mouth 22 and the upper section for being removably attachable to lower section hot mouth 22
Longitudinally 16 coaxial extension, lower section hot mouth 22 are connected with sharp-tongued 15 for hot mouth 24, lower section hot mouth 22 and upper section hot mouth 24, and
Lower section hot mouth 22 defines the second flow channel 26 being connected with first runner 20, and upper section hot mouth 24 defines and 26 phase of second flow channel
The third flow channel 28 of connection.The plastics of molten condition are successively from third flow channel 28, second flow channel 26, first runner 20 by opening
19 enter in the type chamber of mold, to be poured.
In the present embodiment, since hot mouth 14 is equipped with the upper section hot mouth 24 and lower section hot mouth 22 that can mutually dismantle, with sharp-tongued 15
The lower section hot mouth 22 of cooperation guarantees certain machining accuracy, and upper section can suitably reduce machining accuracy, so that processing cost is lower,
And reach in the case where meeting normal injecting condition minimum design, the outer diameter of lower section hot mouth 22 is smaller so that mold open frame 12 compared with
It is small, to increase the template strength of mold, and smaller due to opening frame 12, so that process time is shorter, substantially increase life
Produce efficiency.In addition, it is two sections that hot mouth 14, which is divided to, two sections of length on longitudinal axis length direction is shorter respectively, it is not easy to it deforms,
Therefore it avoids and interferes with mold.
The periphery of lower section hot mouth 22 is equipped with primary heater 30, and the periphery of upper section hot mouth 24 is equipped with independently of primary heater
30 secondary heater 32.Two mutually independent primary heaters 30 and secondary heater 32 are set, can independently be controlled
The heating temperature of lower section hot mouth 22 and lower section hot mouth 22 convenient for control, and makes temperature equalization.
Further, primary heater 30 and secondary heater 32 are spaced a spacing on the extending direction of longitudinal axis 16
From.As long as it is in a molten state can flow that 32 lower temperature of secondary heater can guarantee sizing material, and to temperature
It controls of less demanding.Primary heater 30 is heated by lower section hot mouth 22 to sharp-tongued 15, requires to compare to the control of temperature
It is high.Therefore primary heater 30 and secondary heater 32 are spaced apart, reduce cost, and according to lower section hot mouth 22 and upper
The different heating demand of section hot mouth 24 is heated, and is more convenient for controlling, and reduce energy consumption.
Specifically, lower section hot mouth 22 and upper section hot mouth 24 partly overlap on the extending direction of longitudinal axis 16.So that lower section
Connection between hot mouth 22 and upper section hot mouth 24 is more stable.Further, lower section hot mouth 22 is equipped with lower interconnecting piece 34, upper section
Hot mouth 24 is equipped with upper interconnecting piece 36, and upper interconnecting piece 36 is located at the periphery of lower interconnecting piece 34.So set, making lower interconnecting piece 34
Within upper interconnecting piece 36, so that the periphery diameter of lower section hot mouth 22 is smaller, further reduce mold opens frame 12.
Using threaded connection between upper interconnecting piece 36 and lower interconnecting piece 34.Certainly, upper interconnecting piece 36 and lower interconnecting piece 34 it
Between can also use other connection types, as long as upper section hot mouth 24 and lower section hot mouth 22 are fixed together.
To make the connection between upper section hot mouth 24 and lower section hot mouth 22 more reliable and more stable, upper section hot mouth 24 is equipped with inside
The abutting platform 38 of extension, lower section hot mouth 22 are equipped with the boss 40 protruded outward, and upper interconnecting piece 36 is resisted against boss 40, lower interconnecting piece
34 are resisted against abutting platform 38.
Hot mouth component 10 further includes the sprue bush 42 for being connected to lower section hot mouth 22, and in the circumferential direction perpendicular to longitudinal axis 16
On, for portion gate set 42 between hot mouth 14 and sharp-tongued 15, sprue bush 42 is equipped with the cast gate being connected with first runner 20
44, cast gate 44 is connected with sharp-tongued 15 opening 19, and needle longitudinally 16 is moved to open or close cast gate.To carry out
Casting stops casting.
Preferably, it uses and is threadedly coupled between sprue bush 42 and hot mouth 14.It certainly, can also between sprue bush 42 and hot mouth 14
To use other connection types.
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
Protection scope bright, that they are not intended to limit the invention, it is all without departing from equivalent implementations made by technical spirit of the present invention
Or change should all be included in the protection scope of the present invention.
