Problems solved by technology

[0003] The existing wheel hub casting equipment wraps the inner metal liquid by closing the upper and lower molds when casting the wheel hub, but there will be tiny cracks in the upper and lower molds, which may cause the metal liquid to overflow, which not only poses a safety hazard, but also leads to casting There are large burrs in the wheel hub, which reduces the sealing performance of the existing wheel hub casting equipment. Not only that, in the process of wheel hub casting, different parts have different cooling rates due to the amount of metal solution, which reduces the local area of ​​the wheel hub. Thickness, thus reducing the casting accuracy of the existing hub casting equipment

Embodiment Construction

[0026] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0027] like figure 1 As shown, a hub casting system includes a processing table 1, a lower mold 2 and an upper mold 3, the lower mold 2 is fixed above the processing table 1, the upper mold 3 is arranged above the lower mold 2, and the upper mold The mold 3 abuts against the lower mold 2 and also includes two fixing plates 10, two temperature control mechanisms and two sealing mechanisms. The two fixing plates 10 are fixed on both sides above the processing table 1 respectively. One-to-one correspondence with the temperature control mechanism, the temperature control mechanism is arranged between the fixed plate 10 and the lower mold 2, and the two sealing me...

Abstract

The invention relates to a hub casting system. The hub casting system is provided with a machining table, a lower die and an upper die, and further comprises two fixing plates, two temperature controlmechanisms and two sealing mechanisms. Each sealing mechanism comprises a lifting assembly, a moving assembly and a sealing assembly. Each sealing assembly comprises a first air pump, a first air cylinder, a first piston, a push plate, a sleeve and an injection tube. Each temperature control mechanism comprises a drive assembly, a drive rod, a transmission rod, a driven rod, a cooling block and areset assembly. According to the hub casting system, the upper die or the lower die is locally cooled through the temperature control mechanisms, so that the local cooling speed is increased, the probability that molten metal at the local position flows around is lowered, and accordingly the casting precision of the hub casting equipment is improved; and as a gap between the upper die and the lower die is filled up through the sealing mechanisms, the molten metal is prevented from flowing out from the gap, and thus the sealing performance of the hub casting equipment is improved.

Description

technical field [0001] The invention relates to the field of hub casting equipment, in particular to a hub casting system. Background technique [0002] The hub is a barrel-shaped, center-mounted metal part on the axle that supports the tire inside the tire. The wheel hub is also called the rim, the steel ring, the wheel, and the tire bell. Wheel hubs are of a great variety because of their different diameters, widths, molding methods, and materials. Wheel hub casting equipment, that is, equipment for casting wheel hubs. [0003] The existing wheel hub casting equipment wraps the inner metal liquid by closing the upper and lower molds when casting the wheel hub, but there will be tiny cracks in the upper and lower molds, which may cause the metal liquid to overflow, which not only poses a safety hazard, but also leads to casting There are large burrs in the wheel hub, which reduces the sealing performance of the existing wheel hub casting equipment. Not only that, in the ...
