The utility model is described in further detail below in conjunction with Figure of description:
The specific embodiment
As shown in Figure 1, the utility model provides a kind of frame structure of racket, comprise frame 1 and netting twine 2, wherein: described frame 1 comprises frame 11 and following frame 12, be provided with a gap 3 between the upper and lower frame 11,12, be provided with some support components 4 perpendicular to frame 1 in this gap 3, this support component 4 is one-body molded by mould with upper and lower frame 11,12.
As depicted in figs. 1 and 2, describedly go up frame 11, the support component 4 in frame 12 gaps 3 is according to the position and the needed quantity setting of design down so that netting twine about 2 or up and down symmetry wear.The described support component 4 of the utility model embodiment is adjacent in twos to be arranged in the gap 3, and as shown in Figure 3, described netting twine 2 passes per two support components, 4 crisscross formation wire sides that are provided with.Described support component 4 is cylindrical, also can be other default shape, wears as long as help netting twine, and easy fracture does not get final product.
The utility model institute described support component 4 of embodiment can also be evenly to be arranged in the gap 3, and described netting twine 2 passes each support component 4 crisscross formation wire side that are provided with.
Embodiment of the present utility model also provides a kind of mould of frame of racket structure, as shown in Figure 4, it is integrally formed by mould 5, this mould 5 comprises mold 51 and bed die 52, this mold 51 includes the die cavity 7 consistent with the frame shape respectively with bed die 52, wherein, described mould also comprises supporting plate mould 6, and this supporting plate mould comprises inner shoe mould 61 and mill shoe mould 62.
As shown in Figure 6, described inner shoe mould 61 is provided with symmetrical groove 63 with mill shoe mould 62 at the matched moulds edge.
As shown in Figure 6 and Figure 7, described inner shoe mould 61 and mill shoe mould 62 can be inside and outside mode matched moulds and form removal, when moulding with interior mill shoe mould 61 and 62 matched moulds, the symmetrical grooves 63 of its matched moulds edge setting will clip the middle section position of support component 4, its groove 63 behind matched moulds shape and the shape of support component 4 adapt, after moulding, the form removal of inside and outside supporting plate mould is got final product.
The height in the upper and lower frame 11 of the thickness of supporting plate mould 6 described in the utility model and racket and 12 gap 3 is consistent, so that just interior mill shoe is embedded in the gap 3 when moulding.Behind described supporting plate mould 6 matched moulds, its width is greater than the width of mould die cavity 7.
