Description

A kind of sprue bush of H13 mould steel and Ceramic Composite

Technical field

The utility model is related to automotive hub casting field, especially with regard to pouring for a kind of H13 mould steel and Ceramic Composite Muzzle.

Background technology

Wheel hub mould is the equipment of casting hub, mainly including upper die and lower die, side form, upper die and lower die and side form group After conjunction, the casting mold cavity of wheel hub to be cast is formed, when being poured into a mould using high temperature aluminum water, from holding furnace through stalk to sprue bush and casting Moulding chamber is pressed into aluminium water, and after the addition of aluminium water is finished, the wheel hub cooling shaping in die cavity to be cast, upper mould, side form are started to open at, will The wheel hub of shaping takes out.In low pressure casting aluminum alloy wheel hub production process, in order to alleviate what the frequent wash zone of high temperature aluminum water came Mould is corrosion-damaged, and sprue bush is installed at mould gate.

At present, the making of domestic aluminium alloy wheel hub mould sprue bush is generally made or Steel material system using ceramic material Into, but the two all respectively has quality.The sprue bush being made of ceramic material, although avoid aluminium water and aluminum alloy wheel well Hub mould is contacted, but because aluminium coolant-temperature gage is too high, easily causes the cost of bursting for sprue bush, each sprue bush to exist 50 yuan or so, one, Renewal process influence production need to be just changed after bursting；The sprue bush being made of Steel material, although can Withstand high temperature, be difficult to burst, but be vulnerable to the corrosion of aluminium water, the cost of usual each sprue bush in 20-30 units or so, Corrosion in probably 16-24 hours or so is just very serious, to the later stage because the corrosion of steel sprue bush will have a strong impact on production；Due to sprue bush Damage cause the expensive (damage of the aluminium alloy wheel hub mould of usual 100,000 or so), so as to be caused to wheel hub manufacturing enterprise Economic loss, and have a strong impact on production efficiency.

The content of the invention

The utility model is in order to solve the deficiencies in the prior art, there is provided a kind of sprue bush without frequently changing, So as to improve the production efficiency of wheel hub, improve production quality and steady production technique.

To reach above-mentioned purpose, the utility model mainly provides following technical scheme：A kind of H13 mould steel and Ceramic Composite Sprue bush, it is characterised in that：It includes the sprue bush body being made of H13 mould steel, and the sprue bush body is by one The lower edge of shaping and aluminium water gate spool are constituted, and the lower edge is set on the lower mould of aluminium alloy wheel hub mould；It is described Annular groove is provided with the outer wall of lower edge and the aluminium water gate spool junction；Scribbled on the inwall of the aluminium water gate spool Ceramics, the ceramic thickness is 1mm；The ceramics use zirconia ceramics or aluminium oxide ceramics；The height of the sprue bush body It is 25mm to spend；The height of the lower edge is 5.2mm, and the overall diameter of the lower edge is 69.1mm；The outer wall it is a diameter of 59.2mm, a diameter of 34mm of the inwall；The height of the annular groove is 4mm, and depth is 1.1mm.

Due to taking above technical scheme, it has advantages below to the utility model：The utility model uses H13 mould steel The sprue bush body being made, sprue bush body is made up of integrally formed lower edge and aluminium water gate spool, and lower edge is set in aluminium On the lower mould of alloy wheel hub mould；Ring is provided with the outer wall of the aluminium water gate spool of lower edge and aluminium water gate spool junction Connected in star；Ceramics are scribbled on the inwall of aluminium water gate spool, the ceramic thickness is 1mm, and the utility model is due to using in H13 moulds Tool Steel material simultaneously scribbles ceramics on the inwall for flowing through aluminium water, so as to can solve easily to be fried using ceramic sprue bush non-refractory The problem split, can solve the problems, such as due to using Steel material perishable again, so that extend the service life of sprue bush, without frequency Numerous replacing, so as to improve the production efficiency of wheel hub, improve production quality and steady production technique.In view of above reason, this practicality It is new to can be widely applied to automotive hub casting field.
