Abstract

The utility model designs a front-iron and rear-copper cooling device on a casting hot-joint position at the root of a spoke corresponding to an upper die, which takes away heat of a wheel rapidly by a copper rod so as to play a role in cooling. The cooling device is characterized in that (1) in a cooling rod with a copper rod and a mold steel rod being connected together with threads, external threads are arranged on the copper rod, internal threads are arranged on the mold steel rod, the thickness of the other end of the mold steel rod is about 3mm, and the material of the cooling rod is same as that of the upper die or an edge die; (2) a round hole which forms an angle of 45 degrees with the axis of the upper die is processed at the casting hot-joint position at the root of the spoke corresponding to the upper die, the cooling rod in the characteristic 1 is embedded in the hole, and one end of the mold steel rod is contacted with a wheel blank; and (3) another round hole is processed at the casting hot-joint position at the root of the spoke corresponding to the edge die, the cooling rod in the characteristic 1 is embedded in the hole, and one end of the mold steel rod is contacted with the wheel blank.

Description

Copper cooling device behind the iron before the low pressure wheel die
Technical field
The utility model belongs to mould applications, relates to a kind of aluminum-alloy wheel low pressure casting die cooling device.
Background technology
At present, the domestic production aluminum-alloy wheel overwhelming majority all adopts low pressure casting, because of the design feature reason of aluminum vehicle wheel, wheel spoke and wheel rim intersection area are that the spoke root thickness is big, very easily form the casting thermal center in the production, produce defectives such as serious shrinkage cavity, shrinkage porosite, influence properties of product.Processing back shrinkage cavity, shrinkage porosite are come out easily.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of aluminum-alloy wheel low pressure casting die cooling device is provided, and eliminates shrinkage cavity, the shrinkage defect of wheel spoke root.
The technical scheme that its technical problem that solves the utility model adopts is:
The cooling device of copper behind the iron is taken away the heat of wheel fast by copper rod before the casting thermal center Position Design of patrix and the corresponding spoke root of Bian Mo, plays cooling effect, it is characterized in that:
(1) a kind of copper rod and the mould rod iron cooling stick that is threaded togather, external screw thread is arranged on the copper rod, and internal thread is arranged on the mould rod iron, and mould rod iron other end thickness is thin as far as possible to be about 3mm, and its material is identical with patrix or limit mould material.
(2) the casting thermal center position processing manhole of the corresponding spoke root of patrix, damascene feature 1 described cooling stick in the hole, an end of mould rod iron contacts with wheel blanks.
(3) the casting thermal center position processing manhole of the corresponding spoke root of limit mould, damascene feature 1 described cooling stick in the hole, an end of mould rod iron contacts with wheel blanks.
Advantage of the present utility model and beneficial effect are:
1, the utility model combines the characteristic of the corrosion-resistant and copper rod rapid heat dissipation of mould steel, and favorable cooling effect is arranged.
2, copper rod and mould rod iron adopt and are threaded, and it is convenient to change, and can be used as the standard component lot size stock.
3, the mould rod iron is identical with the limit mold materials with patrix, and the coefficient of thermal expansion unanimity can be avoided producing excessive cooperation slit, causes leaking aluminium.
Description of drawings
Fig. 1 is the utility model cooling device schematic diagram;
Fig. 2 is copper rod and mould rod iron schematic diagram;
The specific embodiment
The utility model is described in further detail below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
As shown in Figure 1 and Figure 2, after cooperatively interacting, limit mould 1, patrix 4, counterdie 5 form the wheel blanks die cavity, at limit mould 1 and patrix 4 corresponding spoke root positions, the processing manhole, inlay the cooling stick that copper rod 3 and mould rod iron 2 combine in the hole, mould rod iron 2 one ends are threaded with copper rod, and the other end contacts with blank, thickness is about 3mm, prevents that mainly copper rod is corroded.Utilize the characteristic of copper rod 3 rapid heat dissipations that the heat of blank is taken away, play cooling effect.
Innovative point of the present utility model is:
(1) copper rod is threaded with the mould rod iron, and it is convenient to change.
(2) mould rod iron can prevent that copper rod is corroded, and the gauge control accuracy height of mould rod iron contact blank one end is little to the heat conduction influence of copper rod.
(3) the mould rod iron cooperates with patrix, can guarantee the seal of cooperation, anti-leak-stopping aluminium.

Claims (1)

1. the utility model cooling device of copper behind the iron before the casting thermal center Position Design of the corresponding spoke root of patrix is taken away the heat of wheel fast by copper rod, plays cooling effect, it is characterized in that:
(1) a kind of copper rod and the mould rod iron cooling stick that is threaded togather, external screw thread is arranged on the copper rod, and internal thread is arranged on the mould rod iron, and mould rod iron other end thickness is about 3mm, and its material is identical with patrix or limit mould material.
(2) processing of casting thermal center position and patrix axis manhole at 45 of the corresponding spoke root of patrix, damascene feature 1 described cooling stick in the hole, an end of mould rod iron contacts with wheel blanks.
(3) the casting thermal center position processing manhole of the corresponding spoke root of limit mould, damascene feature 1 described cooling stick in the hole, an end of mould rod iron contacts with wheel blanks.
