Embodiment 1

[0077] The pressurized casting equipment for automobile wheel hubs of the present invention comprises a main body, a casting mold, a movable slide table, a mold clamping oil cylinder, a side mold clamping mechanism, a pressure boosting mechanism and a mold cooling system.

[0078] Such as figure 1 As shown, the main body is formed by fixedly connecting the upper seat plate 1.5 and the lower seat plate 1.13 through the column 1.6.

[0079] Such as Figure 5 combine figure 1 As shown, the casting mold: includes upper mold 3.3, bottom mold 3.10, side mold 3.1 and side gating system 3.6. Such as Figure 4 The shown upper mold 3.3 is fixedly connected with an upper mold fixing base 2.7 by screws 2.6. Such as Figure 5 The shown bottom mold 3.10 is fixedly installed on the lower mold base 1.12 through the mold foot 3.8, and the lower mold base 1.12 is fixedly installed on the lower base plate 1.13. The center of the bottom mold 3.10 is provided with an iron core 3.13, so that t...

Abstract

The invention discloses pressurizing casting device and method for an automobile hub. The device comprises a device body, a casting die, a movable sliding table, a die closing oil cylinder, a pressurizing mechanism, a side die closing mechanism, a quenching device and a control cabinet. The device has the advantages that 1, the pressurizing mechanism is additionally arranged on the basis of the existing gravity device and process; the pressurizing mechanism drives a pressurizing ring above the die to pressurize molten aluminum alloy in a die cavity; 2, a center riser is removed, and an exhaust plug is provided for exhausting; 3, a cooling system is improved, the multi-point multi-form cooling manner is carried out, and therefore, the cooling effect is improved, and the sequential solidifying process of a product can be effectively controlled; 4, a feeding opening forced cooling system is additionally arranged, so that the molten aluminum at a feeding opening can be solidified firstly, and as a result, the molten aluminum in the die cavity can be avoided reflowing. The invention also discloses a casting method of the gravity pressurizing casting device for the automobile hub. With the adoption of the device and method, the yield of castings is more than 99%; the percentage of pass of air tightness of finished product is up to 99.3%, and the elongation is up to 9.5%.

Description

technical field [0001] The invention relates to the technical field of automobile hub manufacturing, in particular to a pressurized casting equipment and casting method for automobile hubs. Background technique [0002] In the 1970s, developed countries began to widely promote the application of aluminum wheels. my country started the construction of aluminum wheel factories in the late 1980s, entered the development period in the mid-1990s, and continued to maintain a strong growth momentum. By 2006, the annual production capacity of aluminum wheels for automobiles and motorcycles in my country has exceeded 65 million pieces. According to industry statistics, in 2006, it produced 34 million pieces of aluminum wheels for automobiles, of which 18 million were exported; it produced 28 million pieces of aluminum wheels for motorcycles, of which 4 million were exported; it is the largest producer of aluminum wheels in the world. [0003] With my country's accession to the WTO,...
