As a kind of preferred version, the rear end diameter of cylinder open described in the utility model is less than the middle front part diameter of cylinder open.
As another kind of preferred version, outside outer injection mould described in the utility model, be enclosed with cooling-part.
As another kind of preferred version, through hole described in the utility model, yarn hole, tap and hole for injecting glue are multiple.
As another kind of preferred version, the rear end sidewall of cylinder open described in the utility model is provided with bent angle.
Secondly, the number of hole for injecting glue described in the utility model is 2-8.
In addition, outer injection mould front end described in the utility model adopts metal pattern.
The utility model beneficial effect.
Be provided with the first cone-shaped cavity between injection mould and outer injection mould in the utility model, be provided with opening along its length in the middle part of interior injection mould, open front is cylindrical, and opening postmedian is taper, and opening postmedian is provided with taper injection mould; Make the fiber after impregnating resin be subject to the compressing of die cavity, be conducive to discharging bubble, reduce the voidage of composite, improve mechanical property.Adopt the utility model technique, resin is at injection mold cavities internal circulation flow, and resin utilization rate is high, and does not expose and can effectively avoid the resin system moisture absorption in atmosphere.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described further.The utility model protection domain is not only confined to the statement of following content.
Fig. 1 is the utility model injection pultrusion mould structure schematic diagram.
In figure, 1 be yarn hole, 2 be outer injection mould, 3 be interior injection mould, 4 be tap, 5 be cooling-part, 6 for hole for injecting glue, 7 be that the first cone-shaped cavity, 8 is for cylinder open.
Detailed description of the invention
As shown in the figure, the utility model injection pultrusion mould comprises outer injection mould 2, is provided with interior injection mould 3, is provided with the first cone-shaped cavity 7 between interior injection mould 3 and outer injection mould 2 in outer injection mould 2; The anterior circumference of interior injection mould 3 is connected with outer injection mould 2, and this circumferential connecting portion is provided with cross through hole; Opening is provided with along its length in the middle part of interior injection mould 3, open front is cylindrical, and opening postmedian is taper, and open front is communicated with described first cone-shaped cavity 7 front end, opening postmedian is provided with taper injection mould, is the second cone-shaped cavity between taper injection mould and opening postmedian sidewall; Taper injection mould rear end circumference is connected with outer injection mould 2, and this circumferential connecting portion is provided with crosswise yam hole 1, and yarn hole 1 is communicated with described first cone-shaped cavity 7 rear end, the second cone-shaped cavity rear end; Described outer injection mould 2 front end is outlet, exports and is communicated with described first cone-shaped cavity 7 front end; Described outer injection mould 2 front end side wall is provided with vertical tap 4, and tap 4 is communicated with described first cone-shaped cavity 7 front end; Described outer injection mould 2 rear portion is provided with vertical hole for injecting glue 6, and hole for injecting glue 6 is communicated with described first cone-shaped cavity 7 rear portion.
