The invention discloses a spinning wheel intensive-cooling die. A head die adopts a split type, an edge part adopts copper or copper alloy, an edge die adopts a split type, a connecting position of the edge die and the head die adopts copper or copper alloy, a bottom die adopts a split type, and a position of the bottom die corresponding to the outer wheel rim position of a wheel blank adopts copper or copper alloy. The split head die is characterized in that the copper or copper alloy part is provided with a copper tube group, the split edge die is characterized in that the copper or copper alloy part is provided with a copper tube group, and the split bottom die is characterized in that the copper or copper alloy part is provided with a copper tube group. The internal diameter and the wall thickness of each of copper tubes in the copper tube group are 4-8mm and 0.5-2mm respectively, a spacing between adjacent copper tubes is 2-8mm, and a spacing between one of the copper tubes and a mold wall is 3-20mm.
Description
technical field [0001] The invention relates to a metal mold. In particular, it relates to spinning wheel molds. Background technique [0002] The load of a car wheel is about 500kg, and that of a truck wheel is 10 times that. Therefore, the mechanical performance requirements of truck wheels are higher and more demanding, and most steel truck wheels are currently on the market. Steel wheels have problems such as high energy consumption, slow heat dissipation, and easy cracking. In the prior art, 6061 aluminum alloy can replace steel as truck wheel material by forging process, but forged aluminum alloy wheel manufacturing equipment requires large investment and low material utilization rate. If the casting method can be used to produce truck wheels that meet various performance requirements, the production cost will be greatly reduced. Contents of the invention [0003] Spinning wheel strong cooling mold, the top mold adopts split type, the edge part adopts copper or c...
