Description

Technical Field

[0001] The utility model belongs to the technical field of mold cooling, and particularly relates to a suspended cooling system for a cavity of a mold bottom die. Background Art

[0002] The existing wheel hub processing methods usually adopt casting or die casting. The casting mold generally includes an upper mold, a side mold and a bottom mold, and the three enclose a wheel hub cavity. The upper mold mainly forms the back cavity surface of the wheel hub, the side mold forms the rim surface, and the bottom mold forms the front surface of the wheel hub. Due to the uneven thickness of each part of the mold, the cooling speed of the mold itself and the casting will be affected. Especially in some thick parts on the spoke and bead seat, hot spots are very likely to form. The existence of hot spots will cause thermal stress in the wheel hub casting after solidification, resulting in casting deformation, cracks, etc. The traditional cooling acts on the entire cooling cavity of the mold bottom die to reduce the overall temperature of the mold, without contact and without cliff-like cooling. The existing cooling method directly acts on a certain point or a small area of the mold, with strong cooling effect, making the adjustment range of sequential solidification of the product become narrow. Summary of the Utility Model

[0003] In order to make up for the deficiencies of the existing technology, the utility model provides a suspended cooling system for a cavity of a mold bottom die with simple structure and good cooling effect.

[0004] The utility model is realized by the following technical solutions:

[0005] A suspended cooling system for a cavity of a mold bottom die, including a bottom die, and a cooling air duct is connected to the bottom die. It is characterized in that: a cooling circulating water pipe is fixed on the cooling air duct, the end of the cooling circulating water pipe is connected with a water inlet pipe and a water outlet pipe, the water inlet pipe and the water outlet pipe are adjacent, and the periphery of the cooling air duct is connected with the cooling circulating water pipe through a plurality of fixing pieces.

[0006] The diameter of the cooling circulating water pipe is 12 mm.

[0007] The distance between the cooling circulating water pipe and the bottom die is 3 - 5 mm.

[0008] The distance between the cooling circulating water pipe and the bottom die is 4 mm.

[0009] The beneficial effect of the utility model is that: on the original basis, the temperature of the mold bottom die can be reduced by 10 - 15 degrees, the hot aluminum sticking is reduced, the appearance and finish turning shrinkage porosity are reduced by 50%, and there is no influence on normal feeding.
