Description
Technical field
This utility model relates to aluminum-alloy wheel mould.
Background technology
In wheel pressure casting process, the high temperature aluminum liquid in holding furnace enters die cavity via trumpet assembly, and completes mold filling and solidification processes under the control of pressure.Owing to whole mold system is all in atmospheric environment, when aluminum liquid initially enters casting mold, owing to opening increases suddenly, liquid stream is easily formed injection, the aluminum liquid of rolling directly contacts with air and forms oxide slag inclusion, and with each position of aluminum liquid stream to foundry goods, forms wheel foundry goods slag inclusion；Gas in die cavity remains in cast-internal when aluminum liquid solidifies, and with the formal distribution of pore in flange heart portion, makes wheel foundry goods form the defects such as pore.This problem is particularly acute in the center flange region that thickness is big.Therefore in actual production, discharge the most smooth problem for center flange zone gas, it is necessary to take certain measure, gas can be discharged smoothly, solve that oxide slag inclusion and pore problem easily occur, thus improve the forming quality of wheel.
Summary of the invention
The purpose of this utility model is to provide a kind of mold cavity exhaust apparatus that can significantly improve casting mold center flange vent regions effect.
The technical solution of the utility model is: wheel die die cavity exhaust apparatus is cylindrical shell, and housing is transversal for stepped, and cylindrical shell longer end face arranges storage compression, storing compression cross section is triangle, degree of depth 0.5mm-1mm, drift angle 60-90 degree, the quantity storing compression is 2-3 bar.Store compression and can store residual gas fraction, also can increase the area of dissipation of aluminum liquid.
Medial and lateral, cylindrical shell shorter end face axle sets up air discharge duct, and air discharge duct bottom arranges aerofluxus line.Air discharge duct cross section is semicircle, radius 1mm-3mm, air discharge duct height 10mm-20mm, and air discharge duct 4 quantity is 20-30.Exhaust line, aerofluxus live width 0.1mm-0.3mm are set bottom air discharge duct.Air discharge duct and exhaust line constitute UNICOM's channel that die cavity is internal and extraneous, and gas can be discharged mould smoothly.
The material that this utility model selects steel, aluminum, red copper or other heat conductivilitys good makes, and also can accelerate the setting rate of wheel thickness large part, take into account crystal grain thinning effect while aerofluxus.
This utility model simple in construction, store compression and collected by portion gas, solve survival gas problem, and air discharge duct and aerofluxus are rule and UNICOM mold cavity and external environment, and the gas assembled in central area can discharge mould more smoothly.This utility model can substantially eliminate the easy venthole in wheel casting flange heart portion and the defect of the oxidizable slag inclusion of end face, promotes casting yield.

Detailed description of the invention
As it is shown in figure 1, this utility model wheel die die cavity exhaust apparatus is arranged on backform 1 flange face, with backform 1 flange face matched in clearance.Wheel die die cavity exhaust apparatus is cylindrical shell, and cylinder is transversal for stepped, and cylindrical shell longer end face arranges storage compression 3, storing compression 3 cross section is triangle, degree of depth 0.5mm-1mm, drift angle 60-90 degree, the quantity storing compression 3 is 2-3 bar, in order to store a part of residual gas.
As shown in Figure 4, medial and lateral, cylindrical shell shorter end face arrange 20-30 semicircle air discharge duct 4 of cross section gradual change, air discharge duct 4 radius 1mm-3mm, highly 10mm-20mm vertically.The most in the axial direction, on the basis of the summit of the corresponding air discharge duct 4 in medial and lateral, line cutting 20-30, the exhaust line 5 of high 20-30mm, wide 0.1mm-0.3mm, air discharge duct 4 and exhaust line 5 just constitute the communication passage inside and outside mold cavity, it is ensured that the smooth discharge of gas；Air exhaust loop can select ordinary steel or the more preferable material of the heat conductivity such as aluminum and red copper to make, and so may also speed up the aluminum liquid setting rate in the thick big heart portion of wheel, the mechanical property of improving product.
This utility model simple in construction, by making at backform flange arranging exhaust air ring the gas in wheel center region be easier to discharge, eliminates mould and feels suffocated district, and foundry goods heart portion's pore and end face oxide inclusion defects have obtained effective control.Additionally, by selecting heat conductivility more preferably material to make air exhaust loop, it is also possible to accelerate the rate of cooling of Hou great center flange region, refine cast inside tissue, improve the mechanical property of wheel foundry goods.
