Abstract
The utility model discloses a die capable of improving the mechanical property of an aluminium wheel rim. The die comprises a top die and a side die, wherein the remote end of the top die (9) adopts an inverted gradient design; a straight inclined surface I (7) and a straight inclined surface II (8) are arranged under a cooling air pipe II (2) and a cooling air pipe III (3); a cooling air pipe IV (4) and a heat insulation groove (5) are arranged on the side die (10); and the cooling air pipe II (2) and the cooling air pipe III (3) on the top die (9), and the cooling air pipe IV (4) and the heat insulation groove (5) on the side die (10) are respectively substituted by a heat insulation material I (6) and a heat insulation material II (11). The utility model has the advantages that the cooling of the wheel rim is effectively adjusted, so that the wheel rim is subjected to favorable progressive solidification; and meanwhile, relatively fine and dense micro tissues can be obtained, so as to improve the mechanical property of the wheel rim.
Description
Technical field
The utility model relates to the aluminum vehicle wheel low pressure casting die, relates in particular to a kind of aluminum vehicle wheel mold top holder and Bian Mo.
Background technology
In the production process of aluminum vehicle wheel low pressure casting, there is defective in wheel rim always more or less meeting, causes the performance inconsistency lattice when serious.Especially for the wheel type of some crooked wheel rims with the wheel rim with thick imperial palace wheel procheilon structure, solving or control its casting flaw problem, is founder author's a very large challenge.
Yet the layout of existing mould design, cooling does not also accomplish to take into full account the characteristic of wheel rim, thereby designs pointedly.This has caused in process of production, has the wheel type of difficulty for some, and is usually defective because of the wheel rim problem.Therefore, be necessary mould correspondingly to be designed adjustment to the wheel rim characteristic.
Summary of the invention
The purpose of the utility model is that a kind of mould that improves the wheel rim performance will be provided.
The technical scheme of the utility model is: backform falls gradient at far-end, in order to the influence to the below wheel rim of control cooling duct I, cooling duct II, thereby guarantees that the far-end wheel rim can have a better feeding passage.
In backform set inside cooling duct I; The cooling duct II is set outside backform, and cooling duct II and backform facade fit tightly, and straight inclined-plane I is set below the cooling duct II; In order to the escape direction of control cooling duct II wind, prevent that the cooling duct II from producing unnecessary influence to mould; Below the cooling duct III is set in order to the wheel rim below the cooling, the straight inclined-plane II of escaping in order to control cooling duct III wind equally also is set.
The cooling duct IV is set, needed horizontal cooling when providing thick imperial palace wheel lip to solidify on the mould of limit; Simultaneously, heat dam is set, in order to the cooling of control cooling duct IV influence to the feeding passage.
As the improvement of the utility model, available insulation material I and insulation material II replace cooling duct IV, the heat dam on cooling duct II, cooling duct III and the Bian Mo on the backform respectively.Perhaps only one group of insulation material substitutes.
Said insulation material I, insulation material II are heat-preservation cotton or fire clay.
Through above measure, can regulate cooling effectively to wheel rim, make it can carry out good consecutive solidification, also can obtain the microstructure of tiny relatively densification simultaneously, thereby improve the mechanical property of wheel rim.
Description of drawings
Fig. 1 is a prior art aluminum vehicle wheel mould partial schematic diagram.
Fig. 2 is a kind of mould sketch map that improves aluminum vehicle wheel wheel rim mechanical property of the utility model.
Among the figure: 1-cooling duct I, 2-cooling duct II, 3-cooling duct III, 4-cooling duct IV, 5-heat dam, 6-insulation material I, the straight inclined-plane of 7-I, the straight inclined-plane of 8-II, 9-backform, 10-limit mould, 11-insulation material II.
The specific embodiment
In conjunction with the accompanying drawing and the specific embodiment a kind of mould that improves aluminum vehicle wheel wheel rim mechanical property of the utility model is done further explanation.
As shown in Figure 1, backform falls gradient at far-end, in order to the influence of control cooling duct I 1,2 pairs of belows of cooling duct II wheel rim, thereby guarantees that the far-end wheel rim can have a better feeding passage.
In backform 9 set inside cooling duct I 1; Cooling duct II 2 is set outside backform 9; Cooling duct II 2 fits tightly with the backform facade; And straight inclined-plane I 7 is set below cooling duct II 2, in order to the escape direction of control cooling duct II 2 wind, prevent that 2 pairs of moulds of cooling duct II from producing unnecessary influence; Below cooling duct III 3 is set in order to the wheel rim below the cooling, the straight inclined-plane II 8 of escaping in order to control cooling duct III 3 wind equally also is set.
Cooling duct 4 is set, needed horizontal cooling when providing thick imperial palace wheel lip to solidify on limit mould 10; Simultaneously, heat dam 5 is set, in order to the cooling of control cooling duct 4 to the influence of feeding passage.
As the improvement of the utility model, with insulation material I 6 and insulation material II 11 respectively with backform 9 on cooling duct II 2, cooling duct III 3 and Bian Mo 10 on cooling duct IV 4, heat dam 5 exchange use.Perhaps only one group of insulation material substitutes.
Said insulation material I 6, insulation material II 11 are heat-preservation cotton or fire clay.
Through above measure, can regulate cooling effectively to wheel rim, make it can carry out good consecutive solidification, also can obtain the microstructure of tiny relatively densification simultaneously, thereby improve the mechanical property of wheel rim.
A kind of improved aluminum vehicle wheel mold top holder of the utility model is not limited to the described content of the utility model content and the specific embodiment, inspires other designs that obtain according to the utility model content, all falls into the protection domain of the utility model.
