Abstract
The utility model provides a heat pipe cooling device of a low-pressure casting die aluminium alloy wheel. A heat-conducting working medium of a heat pipe is naphthalene, a housing of the heat pipe is made of carbon steel. The utility model counts the content of the obtained heat-conducting working medium naphthalene and the size of the pipe diameter of the housing according to the needs of heat emitted by the die. During the operation of the utility model, and the liquid-state working medium naphthalene is changed into steam through the endothermic phase change process at one side of the evaporation section, which is contacted with the die and the aluminium liquid. The steam flows to the condensation section under the micro differential pressure, is congealed and liquefied at the condensation section to quickly conduct the heat, and the heat flows back to the evaporation section under the action of a capillary imbibition core to complete a circulation. The heat can be circulated and is continuously conducted, so that the crystallization and solidification of a casting and cooling and heat exchanging of the die temperature can be completed.
Description
Technical field
The utility model relates to a kind of cooling heat transferring device of mould, relates in particular to a kind of device of using hot pipe technique in the heat exchange of aluminum alloy low-pressure casting mold cools down.
Background technology
Aluminum-alloy wheel is as the unique outward appearance breaking piece of car, needs constantly to promote the performance quality of self under the lightweight of the automobile industry of global competition fierceness and low-cost demand.So, promote aluminum vehicle wheel performance quality key is to control the process of setting of foundry goods, promptly controls the cooling heat transferring of casting mould.
Traditional cooling means is air cooling and water-cooled.Lower and the safety of the cost of air cooling, but casting mold requires complicated cooling duct of configuration and suitable wall thickness design, and because The Thermal Capacity of Gaseous is little, efficient and the cooling capacity of adjusting heat flow are not high, and be therefore limited to the castering action of aluminum vehicle wheel performance and production efficiency.Water-cooled obtains the more foundry goods of high-performance quality than the efficient height of air cooling.But the problem that exists is the water circulating apparatus complexity, the easy fouling of aquaporin and getting rusty, and discharge can cause the steam passage safety problems such as mistake, effect that stop inadequately.For a long time forever the problem of aluminum-alloy wheel low pressure casting be under the prerequisite of performance quality and improving productivity, find more stable, effectively control the device of mold cools down heat exchange.
Summary of the invention
For performance quality and the production efficiency that promotes aluminum vehicle wheel, the purpose of this utility model provides a kind of cooling heat transferring device of low pressure casting die.
The technical solution of the utility model is: at the thermal center of aluminum vehicle wheel foundry goods and the corresponding mould position of foundry goods consecutive solidification needs heat pipe is set, strengthens mould cooling heat transferring ability, improve cast properties and casting production efficiency.
In order to reach the quick cooling heat transferring effect of hot pipe technique in the aluminum vehicle wheel low pressure casting die, the technological means of taking is:
Fill the heat-conducting work medium naphthalene in the heat pipe described in the utility model, the thermotube shell material is a carbon steel, calculates the caliber size of the content and the housing of heat-conducting work medium naphthalene according to the needs of mould distribute heat.The utility model when running liquid refrigerant naphthalene becomes steam in evaporator section (side that contact with aluminium liquid with the mould) phase transformation of absorbing heat, under small pressure differential, flow to condensation segment, and at the condensation segment condensation liquefaction, heat is derived fast, and under the effect of capillary wick, flow back to evaporator section, finish a circulation.Heat is exactly by so repeatedly, constantly derives, and has finished the crystallization and freezing of foundry goods and the cooling heat transferring of mold temperature.Thermotube shell external diameter 12mm, internal diameter 8mm, case material are carbon steel, heat-conducting work medium is a naphthalene.300 ℃ to 450 ℃ of heat pipe operating temperatures, the preheat temperature of low pressure casting die are 300 ℃ to 400 ℃.
Advantage of the present utility model is: reduced the casting mould temperature, increased the foundry goods cooling velocity, improved the performance quality and the production efficiency of aluminum vehicle wheel cast article.
