Technical field
The utility model relates to a kind of mould, refers to a kind of multiple material rim mould structure especially.
Background technology
At present, the structure of rim of vehicle wheel generally as shown in Figure 1, the outer shroud place of this wheel rim 1 is provided with draw-in groove 11 in order to cooperating with the tire lip of tire, the both sides, outer end of this draw-in groove 11 are formed with inward flange 12 and engage with the groove in the tire tire lip outside.Because whether tire is connected solid and reliablely with wheel rim, the fit dimension of wheel rim inward flange 12 and intensity are key factors, how to guarantee that therefore the fit dimension of wheel rim inward flange 12 and the intensity of this position are to make the matter of utmost importance of wheel rim.
Existing rim of vehicle wheel mostly adopts carbon fiber reinforce plastic material (being called for short composite wood or multiple material) to make and forms.The forming method of composite products normally is wound into complex fabric cloth tubular and is placed in outside the airbag, perhaps complex fabric cloth is laid on the airbag outer surface, then fiber cloth is positioned in the mould together with airbag, charges into gases at high pressure afterwards in airbag, heating gets final product curing molding.And for wheel rim, because the semi-closed structure of draw-in groove 11, the decision wheel rim must be provided with three extraction-type slide blocks 3 in die ontology 4 when moulding, as shown in Figure 2, can guarantee the demoulding after moulding.There are following disappearance in this mould structure and forming method:
1. because the inward flange position of wheel rim belongs to the fringe region of product; when laying silvalin, need this fringe region is inserted in the corresponding groove of slide block; therefore in process of deployment, always have phenomenon inhomogeneous or the silvalin location difficulty; when hot briquetting; it is good that the flowability of the complex fabric cloth after the heating also can not show a candle to liquid plastic; therefore after moulding; the fringe region of this inward flange forms the phenomenon of long-pending yarn, yarn clipping or starved through regular meeting; wheel rim all must carry out secondary operations after moulding for this reason, can guarantee fit dimension substantially.But,, secondary operations will form waste product even can not guaranteeing size for the bigger moulding product of starved.And, the also fit dimension problem just that can solve by secondary operations, and this fringe region causes intensity to descend because long-pending yarn makes the layer that is produced after the moulding phenomenon that has some setbacks certainly will influence this regional intensity.
2. traditional wheel rim mould since must three slide blocks can the demoulding, this mould structure complexity, the die cost height easily causes die deformation, damage etc. in operation process.
The utility model content
It is a kind of simple in structure that technical problem to be solved in the utility model is to provide, and can improve the multiple material rim mould structure of moulding wheel rim in cooperation position intensity.
For solving the problems of the technologies described above, technical solution of the present utility model is:
A kind of multiple material rim mould structure, comprise patrix and counterdie, this upper and lower mould is provided with the die cavity identical with the wheel rim external surface shape, this mould directly is embedded in the semi-finished wheel rim and the big resistant to elevated temperatures interior embedded part of hardness after also comprising moulding, should be arranged at wheel rim draw-in groove one side by interior embedded part, its cross sectional shape is suitable with wheel rim draw-in groove shape, and its outside, cross section also is provided with one can make wheel rim draw-in groove outer end configured openings lengthening section.
Embedded part is made with nylon or Teflon in described.
After adopting such scheme, the utility model has following beneficial effect at least:
1. after the utility model carries out technique improvement to multiple material rim mould, utilize materials such as nylon or Teflon high temperature resistant, intensity is harder, and can process the characteristic of turning, replace three traditional slide blocks with interior embedded part, directly be embedded in interior embedded part in the semi-finished wheel rim, utilize the mode of following process that interior embedded part is excised in semi-finished wheel rim again, this structure can play the effect of simplifying mould.
2. utilize in the semi-finished wheel rim after interior embedded part directly is embedded in it moulding, need not consider release problems, utilize the characteristic that afterwards to process again, mould is reduced to need not three demouldings, so original product draw-in groove inward flange position dimension can be extended, afterwards the extension are adopted after the moulding mode of turning allowance to excise, the method can be stopped the bad of inward flange zone starved, improve the fiber orthodromic of carbon fiber, intensity is greatly improved, can guarantee fit dimension simultaneously.

The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
What the utility model disclosed is a kind of multiple material rim mould structure, as shown in Figure 3, is preferred embodiment of the present utility model.Described mould comprises patrix 5, counterdie 6 and interior embedded part 7, described patrix 5 and counterdie 6 are provided with the die cavity identical with the wheel rim external surface shape, embedded part 7 is arranged at wheel rim draw-in groove one side in described, its cross sectional shape is suitable with wheel rim draw-in groove shape, the outside, its cross section also is provided with a lengthening section 71 makes wheel rim draw-in groove outer end configured openings, in this embedded part 7 can nylon or harder, the high temperature resistant material that can process turning again of Teflon equal strength make.
During the moulding wheel rim, be laid on outside the airbag 8 multiple yarns and the medial surface of described interior embedded part 7, be positioned over then in the mould, charge into gases at high pressure in airbag 8, moulding simultaneously is heating and curing.During the demoulding, do not need interior embedded part 7 is taken out, directly semi-finished wheel rim is deviate from upper and lower mould 5,6 together with interior embedded part 7.After the moulding, utilize following process that interior embedded part 7 cars are removed again, thereby obtain the finished product wheel rim.
When the mould by said structure carries out the wheel rim moulding, because inward flange position, the wheel rim draw-in groove outside no longer relies on and groove is set and moulding on the slide block, therefore when the molding semi product wheel rim, the size of this inward flange can be extended an allowance a (as shown in Figure 4), by following process this allowance is excised again, thereby with the excision of gum deposit place, with proof strength.
