Abstract
The invention discloses a central heat-insulating hole structure of an aluminum vehicle wheel low-pressure water-cooling casting mold. The central heat-insulating hole structure comprises a top mold and central heat-insulating holes, wherein a top mold and central flange loose piece separated structure is changed to a non-separated entire top mold; meanwhile, a circle of the uniformly-distributed heat-insulating holes are formed in the circumferential direction of a mold separated parting surface between the original top mold and a central flange loose piece; the diameter of each heat-insulating hole is set to 8 mm; the quantity of all the heat-insulating holes and the circumferential diameter of the top mold where the heat-insulating holes are distributed need to be set according to the size of a vehicle wheel flange; and in order to guarantee the service life and the water-cooling heat-insulating effect of the aluminum vehicle wheel low-pressure water-cooling casting mold, the distance between the depth of each heat-insulating hole and the cavity surface reaches 20 mm or above.
Description
Technical field
The present invention relates to a kind of wheel pressure casting water cooling mold structure.
Background technology
For lifting wheel product internal soundness to meet consumer product requirement, and the production efficiency improving wheel product alleviates enterprise's production capacity, and wheel enterprise low pressure casting water cooling mould is widely used further in recent years.But the type of cooling of water cooling mold and construction features are different from air-cooled mould, and maximum difference is in casting process to control cooling by water region, there is a lot of Split mold structure, and therefore Mold Making cost also apparent wind cold mold exceeds a lot.It addition, for from casting technique angle, the most probabilities that die joint generation corrosion overlap can be caused to glue aluminum of mould Split type structure are greatly increased, and affect casting process seriality and castability.
Along with the application with Low Voltage and Water-cooled foundry engieering that is continuously increased of wheel yield becomes a kind of inexorable trend, enterprise will face on the premise of ensureing that implementing water-cooling process smoothly produces, and the most effective and reasonable reduces water cooling mold manufacturing cost and the problem ensureing casting process steady production.
Summary of the invention
Present invention aim at solving and improving prior art problem encountered, it is provided that a kind of reduce water cooling mold cost of manufacture, casting process stability can be improved again simultaneously, reduce corrosion overlap and glue the mould structure of aluminum problem.
The technical solution adopted in the present invention is: a kind of aluminum vehicle wheel Low Voltage and Water-cooled casting mould center insulation hole structure, including backform and center insulation hole.
The Split type structure of backform and center flange loose piece is changed to the overall backform of not split.Meanwhile, the circumferencial direction of original backform and center flange loose piece mould split die joint position arranges the insulation hole that a circle is uniform.The diameter of insulation hole is locked as 8mm, depending on its quantity and the circle diameter being distributed on backform need according to wheel flange size size, for ensureing mold use life-span and water-cooled effect of heat insulation, insulation hole depth distance more than mold cavity surface 20mm.
The present invention can effectively control cooling by water region, ensure the consecutive solidification of casting process, realize the effect of heat insulation of Split mold, and avoid Split mold problem, the problem includes: die deformation problem, stopped the most completely to glue aluminum problem owing to split die joint exists produced corrosion overlap simultaneously.Insulation hole simple in construction of the present invention is feasible, greatly reduces Mold Making cost and manufacture difficulty, also improves the efficiency of mould processing and fabricating, decrease the difficulty that later stage mould is safeguarded by the way of adding overall backform puncher.

Detailed description of the invention
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings.
Inventive die processing method is simple, is designed by the Split type structure of original split backform 2 and center flange loose piece 4, changes to the one backform 9 of not split.Meanwhile, by original backform 2 and center flange loose piece 4 mould split die joint 8 position, change on circumferencial direction, make a call to a uniform insulation hole 10 of circle and substitute.For specification insulation hole 10 diameter dimension to process, then need to determine according to wheel-type size for 8mm, its quantity and the circle diameter being distributed on one backform 9 by unified for its diameter.
Embodiment 1: for 16 cun of wheels, flange diameter 140mm, the circle diameter that insulation hole is distributed on backform is 180mm, uniform 70 holes of quantity, depth distance mold cavity surface 20mm.
Embodiment 2: for 17 cun of wheels, flange diameter 165mm, the circle diameter that insulation hole is distributed on backform is 210mm, uniform 80 holes of quantity, depth distance mold cavity surface 22mm.
Embodiment 3: for 18 cun of wheels, flange diameter 180mm, the circle diameter that insulation hole is distributed on backform is 220mm, uniform 90 holes of quantity, depth distance mold cavity surface 24mm.
