The specific embodiment
With reference to accompanying drawing the preferred embodiments of the present invention are described below.
The embodiment of the invention provides a kind of cylinder valve pin type cold runner adapted to injection system; Comprise: flow passage device 1, cylinder body 2 and needle device 3; Said needle device 3 places the inside of said flow passage device 1; Its needle that has 31 is in transmission connection with cylinder body 2, and said cylinder valve pin type cold runner adapted to injection system also comprises cooling device 4, and said cooling device 4 is arranged on the periphery of the bottom of said needle 31;
Said flow passage device 1 has heating component 13, and said heating component 13 is arranged on the periphery of said cooling device 4 bottoms.
Below specify the structure and the operation principle of cylinder valve pin type cold runner adapted to injection system of the present invention.
In conjunction with referring to illustrated in figures 1 and 2, flow passage device 1 is the square shape, and it is fixedly to be formed by 11 stacks of multilayer template, and template 11 can be arranged to the thickness of different size according to the assembling and positioning needs of reality.Multilayer template 11 connects fixing through locking positioning assembly 12.During enforcement, locking positioning spare 12 comprises top button (figure does not show) and is fastened on the tight locking button 122 on multilayer template 11 lateral bodys.
Owing to need cylinder body 2 and needle device 3 be installed in the inside of flow passage device 1; During assembling; Top button (figure does not show) can play positioning action to the installation of multilayer template 11; Be convenient to keep the relative position of 11 of each templates, tight locking button 122 is that multilayer template 11 is held fixing structural member, and it is through fixing, hold or the mode of interference engagement connecting each layer template 11.
Flow passage device 1 also is provided with heating component 13 in the bottom of multilayer template 11; Heating component 13 is structural members that the solvent that is about to be gone out by the extruding of needle 31 tail ends is heated; In the present embodiment; Heating component is with the embodied of heating plate 13, and heating plate 13 is fastened on the distolateral of multilayer template 11; Through heating plate 13 is set, can the solvent that be about to gone out by extruding in the needle 31 be heated like liquid-state silicon gel, make the injecting condition that reaches relevant.
It is understandable that the above-mentioned structure that is used for fixing cylinder body 2, needle device 3 and other parts is through the middle part at multilayer template 11 and heating plate 13 position, hole (figure does not show) to be set to implement.
Cylinder body 2 is parts that power output is provided for needle device 3, and it is fixed on cylinder 21 distolateral cylinder caps 22 and forms with holding by cylinder 21.During enforcement, the fixing seal assembly 32 that cylinder 21 outputs have through needle sealing device 3 is provided with needle 31 and is connected.
Needle device 3 is structural members of realizing in-mould injection through docking with the sealing of mold cavity, and in the present invention, it comprises needle 31 and the fixing seal assembly 32 that is in transmission connection with needle 31 tops, and fixing seal assembly 32 is connected with cylinder 21.
During enforcement, fixing seal assembly 32 is set to sleeve structure, and internal and external walls is held in the above-mentioned hole bit position of needle 31 and flow passage device 1, the effect of playing support fixation and being tightly connected respectively.
Cooling device 4 is to be used to keep needle 31 to be in the structural member of relative low-temperature condition; Through the distinctive radiator structure of offering on it; Reach and make needle 31 ends be unlikely to its temperature to be raise the effect that causes the solvent in the needle 31 to solidify because of the conductive force of multilayer template 11.Be provided with for the hot flow path structure that heat chews at the end of needle 31 with respect to tradition, this cold runner system is more suitable for being applied in the injection moulding apparatus of multi-cavity needle.
Concrete, cooling device 4 comprises that cooling chews 41 and chew sheath 42 with cooling, and cooling chews 41 around the periphery that is arranged on needle bottom 312, and cooling is chewed sheath 42 fixing coolings and chewed 41 inside at flow passage device 1.During enforcement, can make the end of needle 31 remain on relatively low temperature, make the liquid-state silicon gel of the multi-solvent in the needle 31 remain on metastable state, prevent that liquid-state silicon gel wherein from not solidifying before reaching gum outlet because cooling chews 41.
Preferred embodiment, can chew to be provided with on 41 in cooling and be communicated with tank 411, be communicated with tank 411 shape in the shape of a spiral, its embedding be fixed on cooling and chews on 41 the outer wall.Like this,, be used to absorb cooling and chew the heat around 41, make the terminal temperature of needle remain on relatively-stationary numerical value through in being communicated with tank 411, circulation waterway being set.
Cylinder valve pin type cold runner adapted to injection system of the present invention in the specific implementation; Cylinder 21 drives needle device 3 and carries out operation, docks the corresponding technological process that realizes in-mould injection with the sealing of mold cavity through needle 31, in this process; Owing to being provided with cooling, the end at needle 31 chews 41; Cooling is chewed to be provided with on 41 and is communicated with tank 411, through in being communicated with tank 411, being provided for absorbing the circulation waterway that the heat around 41 is chewed in cooling, can make the terminal temperature of needle remain on relatively-stationary numerical value.
And then, the solvent that will soon be gone out by extruding in the needle 31 gets into the runner zone that heating plate 13 is set, and the liquid-state silicon gel in 13 pairs of needles 31 of heating plate heats, and it is solidified, and curing reaches relevant injecting condition.
The cylinder valve pin type cold runner adapted to injection system that the embodiment of the invention provides; Owing to comprise the cooling device of the bottom periphery that is arranged on needle and the heating component that is arranged on cooling device bottom periphery; Solvent in the needle is maintained a relatively stable state before extruding, prevent its curing; Earlier cool off the structure setting of afterwards heating and make this cold runner system be more suitable for being applied in the Shooting Technique of multi-cavity needle, compact conformation is convenient to dismounting; Save injected plastics material, reduced production cost.
Above disclosedly be merely preferred embodiment of the present invention, can not limit the present invention's interest field certainly with this, the equivalent variations of therefore doing according to claim of the present invention still belongs to the scope that the present invention is contained.
