Abstract
The invention discloses a heat pipe cooling device for a low-pressure casting mould for a wheel. A pouring cup is arranged in the middle of a bottom mould; the upper part of the pouring cup is a split-flow cone; side moulds are arranged on two sides of the bottom mould; a heat pipe at a rim, a heat pipe at a hot joint and a heat pipe at a wheel center are arranged on a top mould; and a pouring sleeve is arranged on the pouring cup. By the heat pipe cooling device for the low-pressure casting mould for the wheel, the temperature of the casting mould is reduced, the cooling speed of a casting piece is increased, and the performance quality and the production efficiency of an aluminum wheel casting product are improved.
Description
Technical field
The present invention relates to technical field of mold, relate in particular to a kind of cooling device of mould.
Background technology
Traditional cooling means is air cooling and water-cooled, lower and the safety of the cost of air cooling, but casting mold requires the complicated cooling duct of configuration and suitable wall thickness design, and because the thermal capacitance of gas 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 is higher than the efficient of air cooling, obtains the more foundry goods of high-performance quality.But it is complicated that the problem that exists is water circulating apparatus, the easy fouling of aquaporin and getting rusty, and discharge can cause the steam passage safety problems such as mistake, effect that stop not.
Summary of the invention
The defects that exists in order to overcome the traditional moulds cooling means the invention provides a kind of wheel heat pipe cooling device of low-pressure casting die aluminium.
The technical scheme that the present invention adopts for achieving the above object is: the wheel heat pipe cooling device of low-pressure casting die aluminium, the bed die middle part is provided with cup, cup top is spreader, and the limit mould is installed on the bed die both sides, and backform is provided with wheel rim place heat pipe, thermal center place heat pipe and core wheel place heat pipe.
Described cup is provided with and waters cover.
Wheel heat pipe cooling device of low-pressure casting die aluminium of the present invention has reduced the casting mould temperature, has increased the foundry goods cooling velocity, has improved performance quality and the production efficiency of casting aluminum wheels product.
Description of drawings
Fig. 1 is the structural representation of wheel heat pipe cooling device of low-pressure casting die aluminium of the present invention.
The specific embodiment
The structure of wheel heat pipe cooling device of low-pressure casting die aluminium of the present invention as shown in Figure 1, the wheel heat pipe cooling device of low-pressure casting die aluminium, bed die 5 middle parts are provided with cup 9, cup 9 tops are spreader 7, limit mould 3 is installed on bed die 5 both sides, backform 2 is provided with wheel rim place heat pipe 1, thermal center place heat pipe 4 and core wheel place heat pipe 6, and cup 9 is provided with and waters cover 8.Thermotube shell external diameter 12 is sympathized, and internal diameter 8mm, inside heat pipe have heat-conducting work medium tea, and the thermotube shell material is carbon steel, calculates the content of heat-conducting work medium tea and the pipe diameter size of housing according to the needs of mould distribute heat.The liquid heat conductive working medium bitter edible plant becomes steam in evaporator section (side that contacts with aluminium liquid with mould) heat absorption phase transformation during running, 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, 300 ° of C to 450 ° of C of heat pipe operating temperature, and the preheat temperature of low pressure casting die is 300 ° of C to 400 ° of C.
