Problems solved by technology
[0003] Existing aluminum alloy wheel low-pressure casting molds produce a blank with one mold. If there are products with multiple offsets and different flange diameters in one blank, there are currently two options. The first option is to choose the product with the smallest offset. Mold making, casting a blank, and using one blank to obtain multiple products with different offset distances by machining. In this scheme, when producing products with large offset distances, the amount of machining chips is large, the processing time is long, and the tool is easy to wear. And the metal utilization rate is low; the second option is to classify according to the difference in offset distance, and then make molds with different offset distances according to the classification results, and finally obtain the final product by machining
This solution wastes mold materials and increases mold manufacturing costs

Embodiment Construction
[0011] specific implementation
[0012] The present invention will be further described below in conjunction with accompanying drawings and examples.
[0013] Such as figure 1 As shown, a split top mold for low-pressure casting of aluminum alloy wheels is a part of the low-pressure casting mold for aluminum alloy wheels, and cooperates with the bottom mold and side molds to form the blank of aluminum alloy wheels. Then through machining and spraying process to form the final product. figure 1 The middle mold core (1) and the mold body (2) are parted at the bevel of the wheel flange, and the parting surface adopts a small plane compaction fit, and the size of the parting surface is 4mm-7mm. The mold core (1) and the mold body (2) are positioned by notches and pins, and the screws are detachably connected.
[0014] Such as figure 2 As shown, the mold core (1) is provided with a φ20 vent hole (9), a φ20 ejector hole (10), a φ12 vent hole (5) and a mating end surface (7), and...

The invention relates to an aluminum alloy wheel low-pressure casting split type ejection mold, and belongs to the field of aluminum alloy casting molds. The aluminum alloy wheel low-pressure casting split type ejection mold is characterized in that the split type ejection mold is composed of a mold core (1) and a mold body (2), and the mold joint is designed to be a horizontal straight face and corresponds to the flange slope position of a wheel; the mold core (1) is provided with phi 20 exhaust holes (9), phi 20 ejection holes (10), phi 12 air holes (5) and a mold core matched end face (7); the mold body (2) is provided with phi 12 air holes (6) and a mold body matched end face (8), and the inner diameter of the mold body matched end face (8) is 3 mm larger than the inner diameter of the mold core matched end face (7). The aluminum alloy wheel low-pressure casting split type ejection mold has the advantages that the wheels with different offset distances, different flange diameters and the same appearance modeling can be turned into different products by changing the mold cores of different structures, so that machining time is shortened, the metal utilization rate is improved, and production cost is lowered.
