Abstract
The utility model relates to a metal founding mould of high accuracy bumper shock absorber hub for the casting is bumper shock absorber and hub spare part for the car, a metal founding mould of high accuracy bumper shock absorber hub, including lower mould 1 and last mould 2, lower mould and last mould enclose into a die cavity, its characterized in that: lower mould 1 is equipped with sprue gate 4, sprue gate hole shape be obconical and with die cavity UNICOM, leave the air channel on the die joint of last lower mould to gas spills over, prevents that the gas pocket from producing.
Description
Technical field
The utility model relates to a kind of Metallic Casting Die & Mold, in particular for the Metallic Casting Die & Mold of casting high precision damper (auto parts and components) and high accuracy wheel hub (auto parts and components).
Background technology
Auto parts machinery processing (autospareparts) is the product forming the overall each unit of auto parts machinery processing and serve auto parts machinery processing.Along with being growing more intense of auto parts machinery processing market competition, being rooted in the hearts of the people of environmental protection concept, and the continuous upgrading of technology and application, international automobile accessory process component industry presents following Characteristics of Development in recent years: 1. auto parts machinery system of processing is supporting, modularization supply trend is in the ascendant; 2. auto parts machinery processing sourcing globalization; 3. auto parts machinery secondary industry transfer velocity is accelerated.
The formation of auto parts and components mainly contains 12 and is greatly: engine fittings, power train accessory, braking system accessory, steering system accessory, Running System accessory, electrical instrumentation system accessory, automobile lamp, automobile repacking, safe antitheft, automotive trim, automobile exterior, vehicle body and annex etc.Running System accessory comprises again: back axle, airsuspension system, balance weight, steel plate, tire and wheel hub, leaf spring, semiaxis, damper, steel ring assembly, half axle bolt, axle housing, frame assembly, Luntai, propons.
Damper and wheel hub select magnesium base alloy or acieral to make usually, and the quality of these two parts is by the life-span of the stationarity He other parts that directly affect running car.Conventional metals mold casting process easily makes foundry goods produce pore, and the surface quality not only affecting foundry goods affects the serviceability of foundry goods more; For avoiding the generation of pore, now study following methods.
Utility model content
The utility model, in order to solve existing mold Problems existing, providing a kind of metal casting modeling of high accuracy damper wheel hub, by outputing several air channels on the die joint of upper and lower mould, so that gas overflowing, preventing the generation of Casting Blowholes.
For realizing the purpose of this utility model, a kind of metal casting modeling with a kind of high accuracy damper wheel hub is provided, comprise counterdie (1) and patrix (2), described counterdie and patrix surround a die cavity, it is characterized in that: in described counterdie (1), be provided with sprue gate (4), described sprue gate internal via shape be inverted cone shape and with die cavity UNICOM, the die joint of described upper and lower mould is outputed the air channel that at least one makes gas overflowing.
Preferably, the angle of described sprue gate 4 endoporus is 15 °, and dead head, once solidifying die sinking of can loosing core, selects core to replace metallic core;
Preferably, control paint thickness, make foundry goods each several part cooling velocity consistent; Suitable mould temperature is selected according to foundry goods thickness situation; Refining alloy tissue, improves hot tearing ability; Improve casting structure, eliminate wedge angle and wall thickness sudden change, reduce hot cracking tendency.Metal casting modeling of the present utility model, the die joint of described upper and lower mould outputs air channel, is effectively convenient to gas overflowing, prevents pore from producing.
Detailed description of the invention
Embodiment of the present utility model is described with reference to the accompanying drawings, as shown in the figure, a metal casting modeling for high accuracy damper wheel hub, for casting of automobile damper and wheel hub parts, comprises counterdie 1 and patrix 2, described counterdie and patrix surround a die cavity, described counterdie 1 is provided with sprue gate 4, described sprue gate internal via shape be inverted cone shape and with die cavity UNICOM, the die joint of described upper and lower mould has one or more air channel, so that gas overflowing, prevent pore from producing.
Sprue gate 4 is arranged on counterdie 1, and its endoporus has a gradient, produces certain pressure when being convenient to cast, and promote the discharge of gas, such as sprue gate endoporus gradient is 15 °.When dead head solidifies, die sinking of can loosing core, core rod can select core also can select metallic core, in order to loose core conveniently, preferably selects core.
In casting process, preferably make foundry goods each several part cooling velocity consistent.Meanwhile, suitable mould temperature should be selected according to foundry goods thickness situation.Refining alloy tissue, also can play the effect improving hot tearing ability.Improve casting structure during design, eliminate wedge angle and wall thickness sudden change as far as possible, will hot cracking tendency be reduced.
Adopt the metal casting modeling of technical solutions of the utility model, the die joint of described upper and lower mould is outputed one or more air channel, be effectively convenient to gas overflowing, prevent pore from producing.
Claims (3)
