Abstract
The utility model discloses a hot nozzle at hot runner, including inside be equipped with hot mouth body that the direct current said and locate the mouth body inside and extend the heat conduction shuttle of hot mouth body, seted up on the heat conduction shuttle a plurality of with the communicating subchannel of direct current way, the sharp -tongued cover of going up have a gluey nut, its characterized in that: the heat conduction shuttle on open and to have one or a plurality of recess. Hot nozzle at hot runner, through being equipped with the recess on the heat conduction shuttle, make the melting plastics that flow from the subchannel fully contact with the heat conduction shuttle, extend the thickness in thermal -insulated chamber. Prevent that melting plastic cooling from solidifying, produce the phenomenon of blockking up and influencing product quality.
Description
Technical field
The utility model relates to hot runner mould technical field, particularly relates to one and can prevent sizing material from cooling, occur the hot runner hot mouth of clogging.
Background technology
Along with the development of injection molding technology, Hot runner Technology applies in injection mold more widely.Hot mouth is the vitals in TOP-TIP, in prior art, as shown in Figure 1, hot mouth 1 is placed in mould 2 and opens in frame 21, hot mouth 1 comprises the hot mouth body 10 that inside is provided with straight channel, with to be located at mouth body 10 inner and extend the heat conduction shuttle 12 of hot mouth body, heat conduction shuttle 12 offers the runner 120 that one or a plurality of and described straight channel communicates; On heat conduction shuttle, cover has a sealing nut 11; In use, the molten plastic that hot flow path runner 120 sprays through heat-insulation chamber 13, then enters product die cavity by note cast gate 14.In heat-insulation chamber 13, due to heat conduction shuttle 12 pairs of molten plastic continuous heatings, and mould 2 outside heat-insulation chamber and sealing nut 11 colder, make molten plastic in heat-insulation chamber, being formed from inside to outside can fluidized bed 131 and heat-insulation layer 132.When hot flow path is used in plastic cement to the occasion that the requirement of hot mouth heat conductivility is higher, due to the restriction in space, can be not enough because of the thickness of heat-insulation chamber 13, plastic cement temperature in heat-insulation chamber declines or solidifies, make fluidized bed thinning or produce without fluidized bed, and cause hot mouth to fill discontented or pyrogenicity mouth blocking to product.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide one effectively to prevent sizing material from cooling, and occurs clogging, affects the hot runner hot mouth of product quality.
For achieving the above object, the technical scheme that the utility model proposes is: a kind of hot runner hot mouth, comprise inside be provided with the hot mouth body of straight channel and be located at hot mouth body interior and extend the heat conduction shuttle of mouth body, heat conduction shuttle offers the runner that a plurality of and described straight channel communicates, on described heat conduction shuttle, cover has a nut, it is characterized in that: described heat conduction shuttle has one or plurality of grooves.
Preferably, when groove is greater than one, described groove is distributed on heat conduction shuttle.
Adopt technique scheme, hot runner hot mouth described in the utility model, by being provided with groove on heat conduction shuttle, enables the molten plastic flowed out from runner fully contact with heat conduction shuttle, prevent molten plastic cooled and solidified, produce clogging and the phenomenon affecting product quality.
Accompanying drawing explanation
Fig. 1 is the structure of hot sprue of hot runner schematic diagram of prior art;
Fig. 2 is hot runner hot mouth schematic diagram described in the utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As shown in Figure 2, hot runner hot mouth described in the utility model, hot mouth 1 is placed in mould 2 and opens in frame 21, hot mouth 1 comprises the hot mouth body 10 that inside is provided with straight channel, with be located at hot mouth body 10 and extend the heat conduction shuttle 12 of mouth body, heat conduction shuttle 12 offers a plurality of runner 120 communicated with straight channel, and heat conduction shuttle has one or plurality of grooves 121; Runner 120 outlet is positioned at heat conduction shuttle groove 121 root, and on heat conduction shuttle 12, cover has a sealing nut 11.In use, the molten plastic that runner 120 sprays through groove 121 and heat-insulation chamber 13, then enters product die cavity by note cast gate 14.Due to heat conduction shuttle 12 pairs of molten plastic continuous heatings, simultaneously because heat conduction shuttle 12 is provided with groove 121, groove 121 makes molten plastic be in the encirclement of heat conduction shuttle, is heated more abundant; And the thickness of heat-insulation chamber also can add heat-insulation layer 132 by fluidized bed 131 by original, be extended to by adding the thickness that heat-insulation layer 132 adds groove 121 by fluidized bed 131.Thus melt plastic cement is obtained fully and the heating continued, effectively prevent plastic cement cooled and solidified, the clogging caused and the phenomenon affecting product quality.
Although specifically show in conjunction with preferred embodiment and describe the utility model; but those skilled in the art should be understood that; not departing from the spirit and scope of the present utility model that appended claims limits; in the form and details the utility model is made a variety of changes, be protection domain of the present utility model.
Claims (2)
