The purpose of the utility model provides a kind of hot mouth device that reduces automobile exterior spare injection defect, the technical problem of easy wire drawing when it not only can solve injection moulding, and simple in structure, cost is low.
The utility model is achieved in that
A kind of hot mouth device that reduces automobile exterior spare injection defect; It includes hot sprue bushing, hot nozzle and cutting structure, and said hot sprue bushing is connected with said hot nozzle and communicates, and said cutting structure is located at the junction of said hot nozzle and said hot sprue bushing; The middle part of said cutting structure is provided with through hole; The diameter of said through hole is less than the internal diameter of said hot nozzle, and said through hole be axially arranged with section, said section is divided into left and right sides two parts with said through hole.
When injection moulding, when the injection moulding base material of high temperature gets into said hot nozzle through said through hole,, the injection moulding base material is separated from the centre through the effect of said section, make the fracture herein easily of injection moulding base material, and the phenomenon that is prone to wire drawing when avoiding injection moulding takes place.
Preferably, the end of said hot nozzle is provided with recess, and said cutting structure is positioned at said recess.
Further; The bottom surface that said cutting structure includes annular wall and extended to its inboard by said annular wall; The outer wall of the inwall of said annular wall and the end of said hot sprue bushing is fitted, and the outer wall of said annular wall and the outer wall of said hot nozzle are fitted, and said through hole is located on the said bottom surface.
Preferably, it also comprises fixed structure, and said fixed structure is fixed said hot nozzle and said annular wall.
Preferably, said fixed structure is pin.
Preferably, the material of said cutting structure is the low material of pyroconductivity, selects the lower material of pyroconductivity for use; When injection moulding; The temperature of the injection moulding base material of the temperature relatively-high temperature of said cutting structure is low, is prone to make the injection moulding base material to rupture herein, has further prevented the generation of wire drawing phenomenon.
Preferably, the material of said cutting structure is preferably low stainless steel of pyroconductivity or copper.
The utility model compared with prior art has following beneficial effect:
The utility model is through setting up cutting structure between said hot sprue bushing and said hot nozzle; The injection moulding base material was cut apart before by said hot nozzle ejection; Thereby make the thermoplastic base material when said hot nozzle sprays, can rupture, and then avoid the generation of wire drawing phenomenon; And the utility model compared with prior art, and is simple in structure, only needs the hot mouth device of existing minimizing automobile exterior spare injection defect is simply transformed, and cost is low.
Description of drawings
Fig. 1 reduces the cutaway view of the hot mouth device of automobile exterior spare injection defect for the utility model;
Fig. 2 is the vertical view of the utility model cutting structure.
The specific embodiment
Embodiment to the utility model is elaborated below in conjunction with accompanying drawing:
Like Fig. 1 and shown in Figure 2; The utility model reduces the hot mouth device of automobile exterior spare injection defect; It includes hot sprue bushing 1, hot nozzle 2 and cutting structure 3; Said hot sprue bushing 1 is connected with said hot nozzle 2 and communicates, and said cutting structure 3 is located at the junction of said hot nozzle 2 and said hot sprue bushing 1.Wherein, the middle part of said cutting structure 3 is provided with through hole 33, and the diameter of said through hole 33 is less than the internal diameter of said hot nozzle 2, and said through hole 33 be axially arranged with section 34, said section 34 is divided into left and right sides two parts with said through hole 33.
When injection moulding, when the injection moulding base material of high temperature got into said hot nozzle 2 through said through hole 33, the effect through said section 34 separated the injection moulding base material from the centre, make the fracture herein easily of injection moulding base material, and the phenomenon that is prone to wire drawing when avoiding injection moulding takes place.
The end of said hot nozzle 2 is provided with recess, and said cutting structure 3 is positioned at said recess.
Further; The bottom surface 32 that said cutting structure 3 includes annular wall 31 and extended to its inboard by said annular wall 31; The outer wall of the end of the inwall of said annular wall 31 and said hot sprue bushing 1 is fitted; The outer wall of the outer wall of said annular wall 31 and said hot nozzle 2 is fitted, and said through hole 33 is located on the said bottom surface 32.
