Abstract
The invention provides a combined cooling low-pressure casting hub die provided with a constant-temperature and constant-pressure water tank. The die comprises a top die body, a bottom die body and a side die body. The side wall of the top of the top die body is close to the inner rim casting position. The side wall of the lower portion of the top die body is close to the spoke casting position. A constant-temperature and constant-pressure water cavity with the top open is formed in the side wall of the top of the top die body. A water tank cover plate is arranged on the constant-temperature and constant-pressure water cavity. A water inlet pipe and a water outlet pipe which communicate with the constant-temperature and constant-pressure water cavity are arranged on the water tank cover plate. A rim heat-insulation groove is reserved between the side wall of the top of the top die body and the side wall of the lower portion of the top die body. The top die body and the bottom die body are each provided with a body water-cooling water channel. The combined cooling low-pressure casting hub die has the beneficial effects that the die is low in bulk temperature and large in temperature gradient; compared with dies which are designed previously, setting time is shortened; rapid cooling can be achieved at the rim position; bad defects generated at the connection position between the wheel diameter and the root of each spoke due to that fact that setting time is too long are reduced; and product performance is improved.
Description
Technical field
The present invention relates to a kind of combination cooling low-pressure casting hub die with constant temperature and pressure water tank.
Background technology
It is weak that the casting rotation product low pressure casting existing mold type of cooling mainly adds chill etc. using air cooling way or heat energy-saving position
Cold mode, consumes higher, little, the unitary mould temperature drift from inner rim to gate location mold temperature gradient, technical cooling can
Control property is poor, and casting efficiency is low.For casting spinning wheel hub, domestic existing main flow manufacture craft adopts low-pressure casting, thick big thermal center
Position cools down based on air-cooled, or using air-cooled plus local thermal center position setting cooling insert or cooling patch disk, design in patch disk
Narrow waters, the weak water-cooling pattern of interval string water, such design mould bulk temperature is higher, and mold temperature gradient is about in 100-
150 degree, the die casting time is partially long, and taking 18 cun as a example, class produces efficiency in 85-90 part.And insert is cooled down with die ontology with patch disk and deposits
Destabilizing factor more it is difficult to ensure technique execution stability, existing mold weak cooling by water mode to casting spinning wheel-type
Thick big wheel rim cooling capacity is not enough, and the mould process dwell time is long, and die casting efficiency is low.
Content of the invention
For solving above technical deficiency, the invention provides a kind of good cooling results, the band constant temperature of die casting efficiency high
The combination cooling low-pressure casting hub die of constant pressure water tank.
The present invention is achieved by the following measures：
A kind of combination cooling low-pressure casting hub die with constant temperature and pressure water tank of the present invention, including backform, bed die and Bian Mo,
Described backform top sidewall casts position, described backform top near interior wheel rim casting unit position, backform lower sides near spoke
Side wall has open-topped constant temperature and pressure water cavity, described constant temperature and pressure water cavity is provided with cistern cover plate, described cistern cover plate
On be provided with the water inlet pipe being connected with constant temperature and pressure water cavity and outlet pipe, stay between backform top sidewall and backform lower sides
There is wheel rim heat dam, described backform and bed die all have body water-cooled water channel.
Window heat dam and Bian Mo water-cooled insert are provided with the mould of above-mentioned side.
Above-mentioned bed die bottom is provided with pawl wind, and backform is provided centrally with spreader water channel.
The invention has the beneficial effects as follows：Bulk temperature bottom of the present invention, thermograde is big, designs the mold solidification time more in the past
Shorten, wheel rim position can quickly cool down, reduce because setting time is long and cause wheel footpath and spoke root delivery position
Bad defect, properties of product are lifted.

Specific embodiment
Below in conjunction with the accompanying drawings further detailed description is done to the present invention：
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, devise flood
The strong water-cooled in chamber, the other main thermal center Position Design body water-cooled of cooperation, it is intended to reduce mould preparation cast temperature, increases mold temperature ladder
Spend to 220-280 degree, improve die casting efficiency.
Specifically include backform 2, bed die 1 and Bian Mo 3, backform 2 top sidewall is near interior wheel rim casting unit position, backform 2 bottom
Side wall casts position near spoke.For casting spinning roller type wheel rim thickness big structure feature, and cast blank is less demanding to wheel rim, knot
Close this design feature, backform 2 top sidewall is outputed open-topped constant temperature and pressure water cavity 13, constant temperature and pressure water cavity 13 is provided with
Cistern cover plate 14, 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.
Using uninterrupted circulation string water in water cavity, permanent hydraulic pressure supplies water cooling mode it is ensured that inner rim is to wheel rim thermal center position mould temperature
Degree is in relatively lower temp state.
Leave wheel rim heat dam 16 between backform 2 top sidewall and backform 2 lower sides, block wheel rim position low temperature to wheel
The impact of spoke is it is ensured that order cools down.1# body water-cooled water channel 4,5# body water-cooled is all had on the downside of backform 2 and bed die 1 outer rim
Water channel 7,8# body water-cooled water channel 10.Mould water-cooled insert 8 when putting setting on thermal center at the outer bead seat of mould 3, and window is set
Heat dam 17.Bed die 1 bottom is provided with pawl wind, and backform 2 is provided centrally with spreader water channel 12.It is aided with bed die 1 setting 2# pawl wind
5,3# pawl wind 6, flange heat dam 15, backform 2 setting 7# pawl wind 9,9# ring wind 11.
This mould bulk temperature bottom, thermograde is big, and this kind of mode design the shortening of mold solidification time more in the past, equally with
As a example 18 cun of wheel hubs, class's yield lifting 30% about.The quick cooling of wheel rim position, reduces and causes because setting time is long
Wheel footpath and the bad defect of spoke root delivery position, properties of product are lifted.
The above is only the preferred embodiment of this patent it is noted that ordinary skill people for the art
For member, on the premise of without departing from the art of this patent principle, some improvement can also be made and replace, these improve and replace
Also should be regarded as the protection domain of this patent.
