The specific embodiment
Below with reference to accompanying drawing preferred embodiment of the present utility model is described.
The utility model embodiment provides a kind of cylinder valve pin type cold runner adapted to injection system, comprise: flow passage device 1, cylinder body 2 and valve needle device 3, described valve needle device 3 places the inside of described flow passage device 1, its needle that has 31 is in transmission connection with cylinder body 2, described cylinder valve pin type cold runner adapted to injection system also comprises cooling device 4, and described cooling device 4 is arranged on the periphery of the bottom of described needle 31;
Described flow passage device 1 has heating component 13, and described heating component 13 is arranged on the periphery of described cooling device 4 bottoms.
Below specify structure and the operation principle of the utility model cylinder valve pin type cold runner adapted to injection system.
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 according to the assembling and positioning needs of reality the thickness of different size.Multilayer template 11 is connected and fixed by locking positioning assembly 12.During enforcement, locking positioning spare 12 comprises top button (not shown) and the tight locking button 122 that is fastened on multilayer template 11 lateral bodys.
Owing to need to cylinder body 2 and valve needle device 3 be installed in the inside of flow passage device 1, during assembling, top button (not shown) 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 by 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 embodies with the form of heating plate 13, and heating plate 13 is fastened on the distolateral of multilayer template 11; By heating plate 13 is set, can the solvent that be about to be gone out by extruding in the needle 31 be heated such as liquid-state silicon gel, make the injecting condition that reaches relevant.
Be understandable that above-mentioned structure for fixing cylinder body 2, valve needle device 3 and other parts is by the middle part at multilayer template 11 and heating plate 13 position, hole (not shown) to be set to implement.
Cylinder body 2 is parts that power output is provided for valve needle device 3, and it is by cylinder 21 and hold and be fixed on cylinder 21 distolateral cylinder caps 22 and form.During enforcement, the fixing seal assembly 32 that cylinder 21 outputs have by needle sealing device 3 arranges with needle 31 and is connected.
Valve needle device 3 is structural members of realizing in-mould injection by docking with the sealing of mold cavity, and in the utility model, 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 respectively the above-mentioned hole bit position of needle 31 and flow passage device 1, plays the effect fixing and that be tightly connected of supporting.
Cooling device 4 is for keeping needle 31 to be in the structural member of relative low temperature state, by the distinctive radiator structure of offering on it, reach and make needle 31 ends be unlikely to because of the conductive force of multilayer template 11 its temperature to be raise the effect that causes the solvent in the needle 31 to solidify.Arrange for the hot runner 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 comprise cooling chew 41 and cooling chew sheath 42, cooling chews 41 around the periphery that is arranged on needle bottom 312, cooling is chewed sheath 42 fixing coolings and is chewed 41 inside at flow passage device 1.During enforcement, can make the end of needle 31 remain on relatively low temperature because cooling chews 41, 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.
Preferred embodiment, can chew 41 in cooling and arrange and be communicated with tank 411, be communicated with tank 411 in the shape of a spiral, its embedding is fixed on cooling and chews on 41 the outer wall.Like this, by in being communicated with tank 411, circulation waterway being set, being used for absorbing and cooling off the heat of chewing around 41, make the terminal temperature of needle remain on relatively-stationary numerical value.
Cylinder valve pin type cold runner adapted to injection system of the present utility model in the specific implementation, cylinder 21 drives valve needle device 3 and carries out operation, dock the corresponding technological process that realizes in-mould injection with the sealing of mold cavity by needle 31, in this process, owing to arranging cooling, the end at needle 31 chews 41, cooling is chewed to arrange on 41 and is communicated with tank 411, by 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 is about to be gone out by extruding in the needle 31 enters 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 utility model embodiment 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; Cool off first the structure setting of heating afterwards 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 disclosed only is the utility model preferred embodiment, certainly can not limit with this interest field of the utility model, and the equivalent variations of therefore doing according to the utility model claim still belongs to the scope that the utility model is contained.
