Abstract
The invention relates to the technical field of molds, in particular to a hub bottom old sprue heat insulation heat preservation cup. The heat insulation heat preservation cup is used for slowing down heat losses of a sprue and comprises a heat preservation cup body, and a groove is formed in the outer side face of the heat preservation cup body; the groove is an annular groove, and the sprue is sleeved with the heat preservation cup body; and the heat preservation cup body is fixedly connected with the sprue. The annular groove is formed in the outer side of the heat insulation heat preservation cup, and a sealed cavity is formed between the annular groove and a hub bottom mold in the manufacturing process, so that the temperature on the surface of the sprue is not prone to losing, and it can be ensured that molten aluminum is not solidified in the sprue, so that the sprue is not blocked. The invention further provides the hub bottom die with the insulation heat preservation cup, and the hub bottom die is provided with the insulation heat preservation cup; and the phenomenon that the temperature of a sprue way is too low, the sprue way is blocked, and the quality of a made hub is unqualified is avoided.
Description
Technical field
The present invention relates to technical field of mold, particularly relate to a kind of wheel hub bed die cast gate heat-insulation and heat-preservation ring and the wheel hub bed die with this heat-insulation and heat-preservation ring.
Background technology
In conventional boss mould gate partial design, cast gate and wheel hub bed die are that point two parts form, this kind of design is in aluminium water cavity filling process, because having larger temperature difference between aluminium liquid and bed die, the heat of aluminium liquid is constantly transferred to bottom die by cast gate, be easy to cause the loose loss of the large calorimetric of gate portions like this, when run into sprue channel less when, the loss of faling apart of this heat can cause pouring head to block, thus the supplementary deficiency of type aluminium liquid is filled in generation, can produce a large amount of casting flaw like this.
Summary of the invention
The object of the invention is to propose a kind of wheel hub bed die cast gate heat-insulation and heat-preservation ring, can reduce or prevent the loss of cast gate temperature sink.
The present invention also aims to propose a kind of wheel hub bed die, this wheel hub bed die can prevent pouring head temperature lower, and causes pouring head blocked, the problems such as the wheel hub made is off quality.
For reaching this object, the present invention by the following technical solutions:
A kind of wheel hub bed die cast gate heat-insulation and heat-preservation ring, for slowing down cast gate heat loss, comprises insulating ring body, the lateral surface of described insulating ring body offers groove, described groove is annular groove, and described insulating ring body is sheathed on cast gate, and described insulating ring body is fixedly connected with cast gate.
Further technical scheme is, described insulating ring body is made up of resistant to elevated temperatures metal material.
A kind of wheel hub bed die, comprise wheel hub bed die cast gate heat-insulation and heat-preservation ring described above, comprise cast gate, described wheel hub bed die cast gate heat-insulation and heat-preservation ring set is located on cast gate, and described wheel hub bed die cast gate heat-insulation and heat-preservation ring welds with cast gate.
Further technical scheme is, the angle between the lateral surface that described cast gate contacts with heat-insulation and heat-preservation ring and horizontal plane is greater than 90 °.
Further technical scheme is, described insulating ring body cross-section is trapezium structure, and angle between the lateral surface of the medial surface of insulating ring body and the angle between horizontal plane and cast gate and horizontal plane is identical.
Further technical scheme is, described wheel hub bed die is also provided with some cooling terminals for cooling wheel hub bed die.
Beneficial effect of the present invention:
Offer annular groove outside heat-insulation and heat-preservation ring of the present invention, airtight cavity can be formed in the fabrication process and between wheel hub bed die, make cast gate surface temperature be not easy to scatter and disappear, can ensure that aluminium water does not solidify in cast gate and cause cast gate to block.
Wheel hub bed die of the present invention, with heat-insulation and heat-preservation ring, can prevent pouring head temperature lower, and cause pouring head blocked, the problems such as the wheel hub made is off quality.
