Abstract
The utility model relates to a high-strength aluminum alloy hub die. The die comprises an upper die, a bottom die and a hub die cavity, wherein the hub die cavity is defined by the upper die and the bottom die, and heat radiating grooves are milled at positions on the upper die or/and the bottom die, which correspond to hub spokes inside the hub die cavity. By the aid of the die, the heat dissipation of spoke middle sections during production is facilitated, and loose waste products of castings, which are caused by the fact that the heat dissipation can not be conducted timely due to local overheating, can be reduced. The reduction of local overheating is achieved, die corrosion can be reduced, the life of the die can be prolonged, crystalline grains can be refined by quick cooling of castings, the mechanical performance of products can be improved, and the production cost can be reduced.
Description
Technical field
The utility model relates to aluminium alloy wheel hub Machining Technology field, concrete a kind of high-strength aluminum alloy hub mold.
Background technology
Hub mold is the visual plant for casting hub, and the principle of casting hub mainly is: use compressed air to pass into the cooling duct of arranging in the mould, and by the setting of technological parameter, the die location of the principle cooling appointment of solidifying in order.More and more fierce along with competition, the raising of production efficiency, the castings production cycle shortens, and foundry goods is easy to overheated causing and loosens, and particularly the spoke middle section position is easily loose.Loose is that casting solidification stops up the tiny cavity that forms in the zone slowly because of the microcosmic Feeding channel between the brilliant arm of interdendritic and dendrite.The loose way that prevents: the setting rate of accelerating to solidify slow zone.The spoke position is strengthened cooling and be can not get the additional generation of aluminium liquid shrinkage cavity in the easy excessively cold product spoke part that causes again.The difficulty that runs into after shortening the production cycle is: the spoke stage casing is not cooled off easily loose, strengthens again easily shrinkage cavity of cooling, so improving production efficiency must solve the cooling problem of spoke middle section position.
The utility model content
For the deficiencies in the prior art, the utility model aims to provide a kind of improving product mechanical performance, prolongs the high-strength aluminum alloy hub mold of die life.
For achieving the above object, the utility model adopts following technical scheme:
High-strength aluminum alloy hub mold, described mould comprise the wheel hub die cavity that patrix, bed die and described patrix and bed die surround, and described patrix is or/and mill in the position of corresponding wheel hub die cavity inner wheel hub spoke on the bed die and be provided with radiating groove.
Preferably, described radiating groove comprises one along the elongated slot of spoke length direction and the circular hole that is arranged at the elongated slot centre position
The high-strength aluminum alloy hub mold that the utility model is set forth; compared with prior art; its beneficial effect is: the utility model by at patrix or/and mill in the position of corresponding wheel hub die cavity inner wheel hub spoke on the bed die and be provided with radiating groove; be conducive to accelerate in the production process heat radiation of spoke middle section position, reduce because the loose waste product of foundry goods that hot-spot can not in time be dispelled the heat and be caused.Reduce the effect of hot-spot: can reduce the mould corrosion, be conducive to prolong die life, improving product mechanical performance (cooling off fast foundry goods can crystal grain thinning, the elevating mechanism performance) reduces production costs.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model high-strength aluminum alloy hub mold;
Accompanying drawing 2 is the structural representation of bed die.
The specific embodiment
Below, by reference to the accompanying drawings and the specific embodiment, high-strength aluminum alloy hub mold of the present utility model is described further, so that clearerly understand the utility model technological thought required for protection.
As depicted in figs. 1 and 2, the high-strength aluminum alloy hub mold comprises the wheel hub die cavity 3 that forms between patrix (not shown), bed die 1 and patrix and the bed die 1, is used for the processing of wheel hub 2 in the wheel hub die cavity 3.In order to add the heat radiation of spoke 21 middle section positions on the wheel hub 2 in the speed production process; reduce because the loose waste product of foundry goods that hot-spot can not in time be dispelled the heat and be caused; at patrix or/and mill in the position of corresponding spoke 21 on the bed die 1 and be provided with radiating groove 11; in the utility model preferred embodiment; only be described in and mill the situation of establishing radiating groove on the bed die 1, mill on the patrix that to establish the radiating groove principle identical with it.Milling the process of establishing radiating groove 11 is, mills in the position of corresponding spoke 21 on bed die 1 first and establishes an elongated slot 111, and the length direction of this elongated slot 111 is consistent with the length direction of spoke 21, then is drilled with a circular hole 112 in the centre position of elongated slot.
For a person skilled in the art, can make other various corresponding changes and distortion according to technical scheme described above and design, and these all changes and distortion should belong within the protection domain of the utility model claim all.
Claims (2)
1. high-strength aluminum alloy hub mold, described mould comprises the wheel hub die cavity that patrix, bed die and described patrix and bed die surround, and it is characterized in that, described patrix is or/and mill in the position of corresponding wheel hub die cavity inner wheel hub spoke on the bed die and be provided with radiating groove.
2. high-strength aluminum alloy hub mold according to claim 1 is characterized in that, described radiating groove comprises one along the elongated slot of spoke length direction and the circular hole that is arranged at the elongated slot centre position.
