Abstract
A hub die comprises a die cavity (1) formed after an upper die (4), a lower die (5) and a side die (2) are closed. The die cavity (1) comprises a rim cavity (1.1), a spoke cavity (1.2) and a mounting flange cavity (1.3), and at least two projections (3) are arranged on the inner surface of the side die (2) corresponding to a cross position of the rim cavity (1.1) and the spoke cavity (1.2). Compared with the prior art, the hub die has the advantages that the projections are arranged on the inner surface of the side die corresponding to the cross position of the rim cavity and the spoke cavity and form a cavity inside a spoke after the die cavity is cast and demoulded, and then the spoke is in a hollow structure, so that a hub with the hollow spoke can be manufactured by the hub die, and the manufactured hub has better comprehensive mechanical property, is capable of bearing larger impact force and is higher in deformation resistance.
Description
Technical field
The utility model belongs to the die apparatus field, particularly relates to a kind of hub mold.
Background technology
At present; The hub mold of prior art comprises upper die and lower die and side form, forms the die cavity of wheel hub after upper die and lower die and the side form closure, side form general along circumferentially be divided into half-and-half or the quartering with conveniently stripped; But the hub mold of prior art can't be produced the wheel hub of spoke hollow; And the intensity of the wheel hub of spoke hollow and toughness are all better, can bear greater impact power, and non-deformability are stronger.
The utility model content
The utility model provides a kind of hub mold that can be used for making spoke hollow wheel hub to above problem.
The utility model overcomes the above problems used technical scheme: a kind of hub mold with following structure is provided; It comprises the die cavity that forms by behind upper die and lower die and the side form matched moulds; Described die cavity comprises wheel rim chamber, wheel raia and the mounting flange chamber that interconnects, and described wheel rim chamber is provided with at least two convexities with the corresponding side form inner surface of wheel raia crossover location.
Compared with prior art, after the utility model adopts above structure, because the wheel rim chamber is provided with at least two convexities with the corresponding side form inner surface of wheel raia crossover location; Then die cavity is after the casting and the demoulding, and protruding inside at spoke forms cavity, thereby makes spoke become hollow structure; So the utility model can be made the wheel hub of spoke hollow; Produced wheel hub has better comprehensive mechanical property, can bear greater impact power, and non-deformability is stronger.
As improvement, described at least two convexities are protruding circumferentially evenly to distribute along side form, then makes side form stressed more even when the demoulding, and the stability of side form when mobile better helps the smooth demoulding, improves yield rate, and then reduces production costs.
Described convexity is four.
Description of drawings
Fig. 1 is the structural representation of the utility model hub mold.
Fig. 2 is the structural representation of the utility model hub mold side form.
As shown in the figure: 1, die cavity, 1.1, the wheel rim chamber, 1.2, the wheel raia, 1.3, the mounting flange chamber, 2, side form, 3, convexity, 4, counterdie, 5, patrix.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment, the utility model done further describing.
Embodiment one
A kind of hub mold as depicted in figs. 1 and 2; It comprises the die cavity 1 that forms by behind patrix 4, counterdie 5 and side form 2 matched moulds; Side form 2 is along circumferentially being divided into the quartering; Described die cavity 1 comprises wheel rim chamber 1.1, wheel raia 1.2 and the mounting flange chamber 1.3 that interconnects, and described wheel rim chamber 1.1 is provided with at least two convexities 3 (this example is four) with corresponding side form 2 inner surfaces of wheel raia 1.2 crossover locations, and protruding 3 size is less than the size less than wheel raia 1.3 certainly.General protruding 3 quantity is identical along circumferential isodisperse with side form 2, makes that like this later stage demoulding is more smooth.
Described four convexities 3 circumferentially evenly distribute along side form 2.Evenly distribute be for wheel hub when the casting, makes the symmetry of mould better, and be easier to the demoulding, otherwise mould is asymmetric; When the demoulding, the dynamic equilibrium that the mould each several part moves is relatively poor, causes demoulding failure easily; And then the generation waste product, and destroy mould, cause unnecessary loss.
Embodiment two
A kind of hub mold; It comprises the die cavity 1 that forms by behind patrix 4, counterdie 5 and side form 2 matched moulds; Side form 2 is along circumferentially being divided into bisection; Described die cavity 1 comprises wheel rim chamber 1.1, wheel raia 1.2 and the mounting flange chamber 1.3 that interconnects, and described wheel rim chamber 1.1 is provided with at least two convexities 3 (this example is two) with corresponding side form 2 inner surfaces of wheel raia 1.2 crossover locations, and protruding 3 size is less than the size less than wheel raia 1.3 certainly.General protruding 3 quantity is identical along circumferential isodisperse with side form 2, makes that like this later stage demoulding is more smooth.
Described two convexities 3 circumferentially evenly distribute along side form 2.
Above embodiment is merely the preferred embodiment of the utility model, and the utility model is not limited only to above embodiment and also allows other structural change, allly in the utility model rights to independence claimed range, changes, and all belongs to the utility model protection domain.
Claims (3)
1. hub mold; It comprises the die cavity (1) that forms by behind patrix (4), counterdie (5) and side form (2) matched moulds; Described die cavity (1) comprises the wheel rim chamber (1.1) that interconnects, wheel raia (1.2) and mounting flange chamber (1.3), it is characterized in that: described wheel rim chamber (1.1) with take turns corresponding side form (2) inner surface of raia (1.2) crossover location and be provided with at least two convexities (3).
2. hub mold according to claim 1 is characterized in that: described at least two convexities (3) circumferentially evenly distribute along side form (2).
3. hub mold according to claim 2 is characterized in that: described convexity (3) is four.
