The technical scheme of the invention has the advantages that the cooling of the spoke root part can be effectively improved through the measures, and the influence of the cooling water channel on the spoke is limited.
Description
Technical Field
The invention relates to a low-pressure casting die for aluminum wheels, in particular to a water-cooling side die and a bottom die for improving shrinkage porosity of spoke roots.
Background
In the production process of aluminum wheel low-pressure casting, spoke roots are very obvious heat knots, shrinkage porosity defects are easy to occur at the spoke roots, so whether the mold design and manually added cooling are reasonable or not can greatly influence shrinkage porosity of spoke root parts, and particularly the problem that the shrinkage porosity of spoke roots is not negligible in the production process of fast beats is solved. However, the current common design cannot thoroughly and effectively solve shrinkage porosity of the spoke root part, and brings great difficulty to speed up production beats.
As shown in fig. 1, for the cooling design of the spoke root part commonly used at present, the side mold insert provided with the water channel 1 adopts common mold steel, the cooling of the spoke root with low heat conductivity is slow, although the cooling water channel 2 is provided on the bottom mold to assist the cooling of the spoke root part, the cooling water channel 2 often affects the feeding of the spoke to the spoke root part, and the provision of the cooling water channel brings more adverse effects. Of course, the shrinkage porosity of the spoke part can ensure the feeding of the spoke part by prolonging the production takt time, adding measures such as heat preservation and the like to the spoke part, but the production efficiency is sacrificed.
Disclosure of Invention
It is therefore an object of the present invention to provide a novel water cooled mold for casting aluminum alloy wheels, thereby overcoming the above problems.
In one aspect of the present invention, there is provided a water-cooled mold for casting aluminum alloy wheels, the water-cooled mold comprising a top mold, a side mold and a bottom mold, characterized in that: the side die comprises a side die frame, a bottom die and a side die insert, wherein the side die frame is arranged on the side die frame; the side die insert is made of copper; the matching surfaces between the side die insert and the side die are respectively provided with contact matching surfaces with the length of 10-15mm at the edges of the inner ring and the outer ring, and a gap of 0.05-0.20mm is reserved between the contact matching surfaces between the side die insert and the side die.
In a preferred aspect of the invention, the mating surfaces between the side die insert and the side die have contact mating surfaces of 12mm length at the edges of the inner ring and the outer ring, respectively, and a gap of 0.10mm is provided between the contact mating surfaces between the side die insert and the side die.
In a preferred aspect of the present invention, in the water-cooled mold, the cooling water channel of the bottom mold is located outside the bottom mold.
The technical scheme of the invention has the advantages that the cooling of the spoke root part can be effectively improved through the measures, and the influence of the cooling water channel on the spoke is limited.

Detailed Description
Example 1
A water-cooling mould for casting aluminum alloy wheel, water-cooling mould constitute its characterized in that by top mould, side form and die block: the side die comprises a side die insert, wherein the inner surface of the side die insert faces to the cavity, the upper surface of the side die is matched with the lower surface of the side die, and the lower surface of the side die is matched with the upper surface of the bottom die; the side die insert is made of copper; the edge die insert is characterized in that the matching surfaces between the edge die insert and the edge die are respectively provided with contact matching surfaces with the length of L1 at the edges of the inner ring and the outer ring, and an L2 gap is reserved between the contact matching surfaces and the edge die insert.
In this example, the following embodiments were taken to conduct the test, the test settings are recorded in table 1:
table 1: parameters of each set of test devices in this example.
Five sets of hubs, 1200 each, were produced using the above five sets of water-cooled molds in an internal research and development shop of the department of credit, inc. And the experimental effect of five experimental groups is measured through the disqualification of the hub caused by shrinkage porosity defect of the spoke part. The results show that test group 2 has the best hub production quality, and has 12 hub disqualification cases, 37 test groups 1, 42 test groups 3, 81 control groups 1 and 54 control groups 2 caused by shrinkage porosity defects of spoke parts.
From this, it can be seen that the mold of test set 2 resulted in a reduction in the hub failure rate due to shrinkage porosity at the spoke root portion.
