Description
Technical field
The present invention relates to a kind of combination cooling low-pressure casting hub dies with constant temperature and pressure water tank.
Background technology
The casting rotation product low pressure casting existing mold type of cooling mainly uses air cooling way or heat energy-saving position to add chill etc. weak
Cold mode, consumption is higher, and small from inner rim to gate location mold temperature gradient, unitary mould temperature drift, technical cooling can
Control property is poor, and casting efficiency is low.For casting spinning wheel hub, domestic existing mainstream manufacture craft uses low-pressure casting, thick big thermal center
Position cools down based on air-cooled, or adds localized heat section to install cooling insert or cooling patch disk using air-cooled, is designed in patch disk
Narrow waters, the weak water-cooling pattern of interval string water, such design mold bulk temperature is higher, and mold temperature gradient is about in 100-
150 degree, the die casting time is partially long, and for 18 cun, class produces efficiency in 85-90 parts.And insert is deposited with patch disk and die ontology cooling
It is more in destabilizing factor, it is difficult to ensure that technique executes stability, the weak cooling by water mode of existing mold is to casting spinning wheel-type
Thick big wheel rim cooling capacity is insufficient, and the mould process dwell time is long, and die casting efficiency is low.
Invention content
To solve the above technical deficiency, the present invention provides a kind of good cooling results, the efficient band constant temperature of die casting
The combination cooling low-pressure casting hub die of constant pressure water tank.
The present invention is achieved by the following measures：
The present invention a kind of combination cooling low-pressure casting hub die with constant temperature and pressure water tank, including backform, bed die and
Bian Mo, the backform top sidewall cast position, the backform close to interior wheel rim casting unit position, backform lower sides close to spoke
Top sidewall is provided with open-topped constant temperature and pressure water cavity, and cistern cover plate, the water tank are provided on the constant temperature and pressure water cavity
Be provided with the water inlet pipe and outlet pipe being connected with constant temperature and pressure water cavity on cover board, backform top sidewall and backform lower sides it
Between there are wheel rim heat dam, be provided with ontology water cooling water channel on the backform and bed die.
Window heat dam and Bian Mo water cooling inserts are provided on above-mentioned side mould.
Above-mentioned bed die bottom is provided with pawl wind, and backform is provided centrally with spreader water channel.
The beneficial effects of the invention are as follows：Bulk temperature bottom of the present invention, temperature gradient is big, relatively designs the mold solidification time in the past
Shorten, wheel rim position can be quickly cooled down, and reduced and caused wheel footpath and spoke root delivery position since setting time is long
Bad defect, properties of product are promoted.

Specific implementation mode
Further detailed description is done to the present invention below in conjunction with the accompanying drawings：
As shown in Figure 1, a kind of combination cooling low-pressure casting hub die with constant temperature and pressure water tank of the present invention, devises
The strong water cooling of big water cavity, coordinates other main thermal center Position Design ontology water coolings, it is intended to reduce mould preparation cast temperature, increase mold temperature
Gradient is spent to 220-280 degree, improves die casting efficiency.
Backform 2, bed die 1 and Bian Mo 3 are specifically included, 2 top sidewall of backform is close to interior wheel rim casting unit position, 2 lower part of backform
Side wall casts position close to spoke.For casting spinning roller type wheel rim thickness big structure feature, and cast blank is of less demanding to wheel rim, knot
This design feature is closed, 2 top sidewall of backform is outputed open-topped constant temperature and pressure water cavity 13, is provided on constant temperature and pressure water cavity 13
Cistern cover plate 14 is provided with the water inlet pipe 13.1 being connected with constant temperature and pressure water cavity 13 and outlet pipe 13.2 on cistern cover plate 14.
It ensure that inner rim to wheel rim thermal center position mold temperature for water cooling mode using uninterrupted cycle string water, permanent hydraulic pressure in water cavity
Degree is in relatively lower temp state.
There are wheel rim heat dams 16 between 2 lower sides of 2 top sidewall of backform and backform, block wheel rim position low temperature to wheel
The influence of spoke, guarantee sequence are cooling.It is provided with 1# ontology water coolings water channel 4,5# ontology water coolings on the downside of 1 outer rim of backform 2 and bed die
Water channel 7,8# ontology water coolings water channel 10.The mould water cooling insert 8 when the outer bead seat of mould 3 is set and is arranged on thermal center, and window is set
Heat dam 17.1 bottom of bed die is provided with pawl wind, and backform 2 is provided centrally with spreader water channel 12.It is aided with bed die 1 and 2# pawl wind is set
7# pawls wind 9,9# rings wind 11 is arranged in 5,3# pawl wind 6, flange heat dam 15, backform 2.
This mold bulk temperature bottom, temperature gradient is big, this kind of mode designed more in the past the mold solidification time shortening, equally with
For 18 cun of wheel hubs, class's yield promotes 30% or so.Wheel rim position is quickly cooled down, and reduction is caused since setting time is long
The bad defect of wheel footpath and spoke root delivery position, properties of product are promoted.
The above is only the preferred embodiment of this patent, it is noted that for the ordinary skill people of the art
For member, under the premise of not departing from the art of this patent principle, several improvement and replacement can also be made, these improve and replace
Also it should be regarded as the protection domain of this patent.
