[0031] Example:

[0032] See also Figure 1-2 As shown, a base casting integrated structure includes a base member 100; the base member 100 is a hollow cylindrical structure in the middle, and an annular protrusion 110 is formed along the outer periphery of one end of the axial direction; the annular protrusion 110 only represents the overall annular shape, and does not limit its structural shape to a perfect circle. It can be as follows Figure 1 The structure that is annular as a whole but has a partial protrusion on its circumference, or a structure that is approximately annular, falls within the scope of protection of the present invention; in one embodiment, the base member 100 and the annular protrusion 110 thereon constitute a flange;

[0033] The outer end surface 111 of the annular protrusion 110 is connected to the pouring gate 200; the annular protrusion 110 is provided at one end of the base member 100. Figure 2 As shown, the annular protrusion 110 is provided on the right side of the base member 100. In this case, the outer end surface 111 refers to the right end surface of the annular protrusion 110. The pouring riser 200 is connected to the outer end surface 111. After the die casting is completed, the top of the annular protrusion 110 does not need to be processed, which can meet the customer's process requirements for specific products. In another embodiment, if the customer does not have die-casting product processing requirements, the pouring riser 200 can be connected to the top of the annular protrusion 110.

[0034] The pouring head 200 includes a connected lap end 210 and a top end 220; the lap end 210 is connected to the annular protrusion 110; in one embodiment, the lap end 210 is connected to the outer end surface 111 or the top surface of the annular protrusion 110; the side of the lap end 210 away from the outer end surface 111 is a first inclined surface 211; the angle between the first inclined surface 211 and the outer end surface 111 is α; the side of the top end 220 away from the outer end surface 111 is a second inclined surface 221; the angle between the second inclined surface 221 and the outer end surface 111 is β; α≥β; the provision of the first inclined surface 211 and the second inclined surface 221 facilitates the feeding and transmission of the casting during die casting, and α is preferably greater than β, which is more conducive to the feeding and transmission; in one embodiment, α=30-35° and β=10-15°;

[0035] In one embodiment, the central angle formed by the lap end 210 and the center of the base member 100 is A; A=60±10°, and the design of the casting follows the casting principle;

[0036] In one embodiment, the maximum width of the lap 210 is B; the thickness of the annular protrusion 110 is b; B is 4-6 times b; the maximum width of the top 220 is C; C is 1.15-2 times B. In this embodiment, the size of the base member 100 is 191.25*191.25*95.37, the maximum thickness of the casting is 20±1mm, the thinnest thickness is 5±0.5mm, and the weight is 2117g. The casting is required to be free of bubbling after heat treatment at 535℃*6H, and no shrinkage porosity is allowed after X-ray inspection; the pouring area of the lap 210 is 22-26cm 2 The maximum width of the end 210 is B = 80.48 ~ 120.72mm, and the cross-sectional area of the top 220 is 62-72cm 2 The cross-sectional area of the pouring riser 200 gradually increases along the extension direction from the lap end 210 to the top end 220. With this design, the cross-sectional area gradually increases toward the top, which is also conducive to filling in the shrinkage and improving the product quality.

A plurality of water cooling channels 310 are provided within the mold 300. At least one of the water cooling channels 310 is disposed adjacent to the heat node 320. In one embodiment, at least one of the water cooling channels 310 is disposed adjacent to the landing 210. In another embodiment, two of the water cooling channels 310 are disposed adjacent to the heat node 320.

[0038] Through numerical simulation of Shichuang Technology, hot spots appear in local parts of castings, which is consistent with the actual X-Ray flaw detection. Figure 5-9 As shown. Due to the thick wall, the shrinkage channel has been closed, so only cooling water can be added to the hot spot on the mold 300 for cooling; Figure 3-4 As shown, by arranging two water cooling channels 310 adjacent to the hot node 320 , the problem can be effectively solved, sequential solidification can be achieved, and the shrinkage feeding effect can be improved, so that the final casting does not have defects such as shrinkage cavities and porosity.
