Description
Technical field
The utility model is related to casting field, cold more particularly to a kind of side mould of low-pressure casting die of aluminium alloy wheel
But structure.
Background technology
Aluminum-alloy wheel spoke is compared thick big with wheel rim junction, is typical casting thermal center, if processing is not in production
When being then easy to occur casting flaw, influence yield rate and sample presentation quality.At this stage, aluminum-alloy wheel production is most of adopts
Use low pressure casting forming technique, top, bottom, side mould together constitute the die cavity of casting, aluminium liquid is completed in the presence of ambient pressure
Solidification forming.For thick big heat energy-saving position, typically realized by the thickness of mould itself and some air channels of arrangement cold
But.But, due to the excessively concentration of heat, existing mould and cooling capacity have been difficult that the heat of aggregation is quick and effective
Shed, such consequence can exactly cause aluminium liquid setting rate slow, and thermal center setting time will be later than front end position, thus because
Feeding channel blocks and occurs the casting flaws such as shrinkage porosite, shrinkage cavity at thermal center.In addition, the crystal grain of cast-internal can be very thick, group
Knit loose not fine and close, cause mechanical property lower, it is impossible to meet the strict demand of client, cause complaint Frequent Accidents.
Utility model content
The purpose of this utility model is to provide a kind of effective mold side mould for weakening thick big thermal center effect.
The technical solution of the utility model is：Improved low pressure casting wheel mold side mould, including water inlet pipe, outlet pipe,
Installation bolt.While mould by while mold framework and water cooling insert constitute.Cavity is set on the mould body of side, side mold framework, cavity is constituted
Positioned at thick big thermal center position, cavity includes thermal conductive surface at upper and lower two, thermal conductive surface Precision Machining, Ra<1.6, it is good to ensure
Heat-conducting effect；The material of side mold framework is cast steel 35CrMo.Water cooling insert is arranged on the mold framework of side, concentrates the thick big heat of cooling
Save position；Water cooling insert includes thermal conductive surface, surface accuracy Ra at corresponding upper and lower two<1.6.
Water channel is set in water cooling insert, and the section of water channel is wide to be set to 8mm, and section high setting is 12mm.Water channel is in bending
Type, in thermal center positional distance cavity surface 20-30mm, in the window's position apart from cavity surface 40-50mm, and in bed die correspondence window
Position set heat dam, to weaken the adverse effect to window area.Circular hole at 2 is set in water cooling insert lateral surface, is used for
Be welded water inlet pipe, outlet pipe, and water pipe is then connected with outside water cooling equipment, to constitute circulation waterway；The material choosing of water cooling insert
Forged steel 35CrMo is used, its dense structure's antileaking；Side mold framework is fastenedly connected with water cooling insert by 4-6 installation bolt.
The utility model is provided with side mold framework, water cooling insert, realizes with cooling by water to replace existing air-cooled shape
Formula, by the powerful heat storage capacity of cooling water, fast and effectively takes away the heat in thick big thermal center region, improves the solidification of aluminium liquid
Speed；Water channel design is curve form, and is processing heat dam to the window's position, makes cooling range more accurate, can concentrate
Heat energy-saving position is cooled down, while the influence that reduction is distributed to window temperature；The application of novel side mould realizes the consecutive solidification of wheel,
Solve thermal center and the problem of shrinkage porosite, shrinkage cavity easily occur；By increasing casting degree of supercooling, cast-internal crystal grain is set to have obtained significantly
Refinement, tissue more even compact, greatly improves the mechanical property of wheel；In a word, the application of novel die improves casting
Forming quality and integrated yield, furthermore achieved that wheel high-quality production.
