Description
Technical field
The utility model relates to aluminum alloy low-pressure casting fields, are used for aluminum-alloy wheel low pressure casting more particularly to one kind
Water cooling mold.
Background technique
In parts industry, for wheel, this had not only required appearance but also had required the peculiar part of performance, especially right
In the performance of spoke, it is desirable that extremely stringent.In aluminum vehicle wheel enterprise, the performance of spoke is improved, the method generallyd use is to reinforce side
Mould is cooling, this method repeatedly uses and effectively in air-cooled mold；However, in water cooling mold, and often occur fitting to obtain it
Anti- effect, basic reason are the unreasonable of side mode water-cooling structure design.Attached drawing 1 is shown as current common water cooling mold
Side mode water-cooling structure schematic diagram, since cooling water channel opens up downward, heat dam only opens up window area, and is that blind hole is heat-insulated
Slot inevitably results in side mode cooling and is better than top to the effect of lower part, this just makes slightly long when the side mode cooling time opened
When a little or flow is slightly bigger, easily there is shrinkage porosite in spoke root.The utility model will provide a kind of improved side mode
Water-cooling structure, to solve current problems faced.
Summary of the invention
Therefore, the purpose of the utility model is to provide a kind of water cooling molds for aluminum-alloy wheel low pressure casting.
In the one aspect of the utility model, a kind of water cooling mold for aluminum-alloy wheel low pressure casting, institute are provided
The water cooling side mode stated includes upper die and lower die and side mode, and the upper die and lower die and side mode are special around the type chamber for going out aluminium alloy
Sign is that the side mode frame of the side mode has been embedded in cooling insert, upper die joint, the lower die joint of the cooling insert
With side die joint respectively with side mode contact therewith parting, and the side die joint includes front area and rear portion straight section area
There is the gap of 1.5-2.5mm in domain between the rear portion straight section region and side mode frame；The upper die joint and lower die joint
Other than the assembly area of 10-15mm width, remaining region and side mode frame distance 0.15-0.25mm；The cooling edge
Include cooling water channel inside block, and includes disengaging water swivel at cooling water channel both ends.
There is the gap of 2mm between the preferred aspect of the utility model, the rear portion straight section region and side mode frame；Institute
The upper die joint and lower die joint stated are other than the assembly area of 12mm width, remaining region and side mode frame distance
0.20mm。
At the preferred aspect of the utility model, the cooling insert is fixed to side mode frame by screw.
At the preferred aspect of the utility model, the cooling insert the spoke direction towards mold be provided with blind hole every
Heat channel.
At the preferred aspect of the utility model, the cooling insert the window direction towards mold be provided with through-hole every
Heat channel.
At the preferred aspect of the utility model, the cooling insert includes sealing baffle on the outside of cooling water channel.
The cooling water channel for including inside the preferred aspect of the utility model, the cooling insert is arranged so that cooling
Water flows from bottom to top.
The advantages of the utility model is as follows: cooling water channel takes straight way to design, and balances the temperature difference at side mode center and two sides, subtracts
The thermal denaturation of few mold；0.2mm empty avoiding on upper and lower die joint can control side mode cooling range, and mold also can be improved
Gas permeability；By being used cooperatively for blind hole and through-hole heat dam, the cooling range of side mode can be further controlled；Water cooling insert is taken
Die life can be improved in embedded assembly method, reduces die cost.
Detailed description of the invention
Hereinafter, the embodiments of the present invention are described in detail in conjunction with attached drawing, in which:
The present invention and specific embodiment are described further with reference to the accompanying drawing.
