Abstract
The utility model relates to an improved hot nozzle. The improved hot nozzle comprises a hot nozzle main body, a hot nozzle core and a glue-sealing cover, wherein the glue-sealing cover is used for fixing the hot nozzle core in the hot nozzle main body; a hot nozzle main body runner is arranged in the hot nozzle main body; a hot nozzle core runner is arranged in the hot nozzle core; the hot nozzle main body runner is communicated with the hot nozzle core main body runner; the hot nozzle core comprises a hot nozzle core step part and a hot nozzle core head part, wherein the joint of the outer periphery of the hot nozzle core step part and the inner wall of the hot nozzle main body is equipped with a steel hot nozzle core protective sleeve. During working, the hot nozzle core protective sleeve can disperse extruding force of the hot nozzle main body and the glue-sealing cover on the hot nozzle core, and can prevent the hot nozzle core from being deformed. The improved hot nozzle disclosed by the utility model is simple in structure and capable of effectively preventing a glue leakage condition caused by deformation of the hot nozzle core.
Description
Technical field
The utility model relates to a kind of improved hot mouth, especially relates to a kind of hot mouth that prevents hot mouth core deform ation prevention leakage glue, belongs to injection mold component technology field.
Background technology
In injection mold, often use hot mouth, the hot mouth of commonly using in prior art, as shown in Figure 1, comprises hot mouth main body, hot mouth core, sealant cover, described sealant cover is fixed on hot mouth core in hot mouth main body; Hot mouth main body and sealant cover are steel, hot mouth core is copper, during work, hot mouth main body heating, because the coefficient of expansion of copper is larger than steel, copper is softer than steel simultaneously, and therefore hot mouth core is by hot mouth main body and sealant cover crimp, when quitting work, heat blunt but after, between hot mouth core and hot mouth main body and sealant cover, produce gap, when hot mouth main body heats again, hot mouth core can not return to original shape, will cause plastic solution to spill from gap, even also can cause product bad, produce stain, the flaws such as yellow black line.
Utility model content
The utility model object is in order to overcome the deficiencies in the prior art, to provide a kind of to prevent that hot mouth core deform ation prevention from leaking the hot mouth of glue.
For achieving the above object, the technical solution adopted in the utility model is: a kind of improved hot mouth, comprise hot mouth main body, and hot mouth core, sealant cover, described sealant cover is fixed on hot mouth core in hot mouth main body; In described hot mouth main body, be provided with hot mouth main body runner, described hot mouth in-core is provided with hot mouth core runner, and described hot mouth main body runner is communicated with hot mouth core main body runner; Described hot mouth core comprises hot mouth core stage portion and hot mouth core head, and the junction of the excircle of described hot mouth core stage portion and the inwall of hot mouth main body is provided with hot mouth core protective sleeve.
Preferably, between described hot mouth core stage portion and sealant cover, be provided with groove, one end of described hot mouth core protective sleeve embeds in described groove;
Preferably, the material of described hot mouth core protective sleeve is steel.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
A kind of improved hot mouth of the utility model scheme, in the excircle of hot mouth core stage portion and the inwall junction of hot mouth main body, be provided with the hot mouth core protective sleeve of a steel, during hot mouth heating, hot mouth main body and sealant cover be not radially, can directly be expressed to hot mouth core on axially, and extruding force has all been disperseed by hot mouth core protective sleeve; Even the temperature distortion of hot mouth core, hot mouth core protective sleeve can also play the effect of sealing, can not cause leakage glue; Improved hot mouth structure of the present utility model is simple, can effectively prevent the leakage glue situation that hot mouth core distortion causes.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
Accompanying drawing 1 is the structural representation of hot mouth in prior art;
The structural representation that accompanying drawing 2 is embodiment described in the utility model;
Wherein: 1, hot mouth body; 2, hot mouth core; 3, sealant cover; 4, hot mouth core stage portion; 5, hot mouth core head; 6, hot mouth core protective sleeve; 7, groove.
the specific embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Accompanying drawing 2 is a kind of improved hot mouth described in the utility model, comprises hot mouth main body 1, hot mouth core 2, and sealant cover 3, described sealant cover 3 is fixed on hot mouth core 2 in hot mouth main body 1; In described hot mouth main body 1, be provided with hot mouth main body runner, be provided with hot mouth core runner in described hot mouth core 2, described hot mouth main body runner is communicated with hot mouth core main body runner; Described hot mouth core 2 comprises hot mouth core stage portion 4 and hot mouth core head 5, and the junction of the excircle of described hot mouth core stage portion 4 and the inwall of hot mouth main body 1 is provided with hot mouth core protective sleeve 6; In the present embodiment, between described hot mouth core stage portion 4 and sealant cover 3, be provided with groove 7, one end of described hot mouth core protective sleeve 6 embeds in described groove 7, and such design makes hot mouth core protective sleeve 6 better disperse the axial compression power from sealant cover 3; The material of described hot mouth core protective sleeve 6 is steel.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
A kind of improved hot mouth of the utility model scheme, in the excircle of hot mouth core stage portion and the inwall junction of hot mouth main body, be provided with the hot mouth core protective sleeve of a steel, during hot mouth heating, hot mouth main body and sealant cover be not radially, can directly be expressed to hot mouth core on axially, and extruding force has all been disperseed by hot mouth core protective sleeve; Even the temperature distortion of hot mouth core, hot mouth core protective sleeve can also play the effect of sealing, can not cause leakage glue; Improved hot mouth structure of the present utility model is simple, can effectively prevent the leakage glue situation that hot mouth core distortion causes.
Below be only concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, within all dropping on the utility model rights protection scope.
