Abstract
A kind of wheel die bed die, the region of bed die mold cavity surface correspondence spoke sets grid lines, and grid lines is divided into radially and circumferentially two kinds, and depth 0.5mm 1mm, radial grid line is obtuse angle with circumferential grid lines angle, and 3 5mm of interval are evenly arranged.On bed die back of the body chamber surface, sawtooth pattern annular groove, radially even distribution are set；Cooling duct is arranged in bed die back of the body chamber, and exhaust vent, exhaust vent direction back of the body chamber surface sawtooth pattern annular groove are set on airduct.The Temperature Distribution of whole bed die that the utility model can make more tends to balance stably, it is ensured that the smooth Accurate Shaping of wheel casting.
Description
Technical field
The utility model is related to a kind of mould, more particularly to a kind of bed die for improving wheel surface quality.
Background technology
Aluminium alloy wheel hub is one of important appearance member on vehicle, and the surface state according to wheel is generally divided into full coat dress
Wheel, smart car wheel, polishing wheel etc. are several, and main engine plants have formulated strict requirements to the front quality of product, are not allow for any
The defect that visual effect can be significantly affected is present.And for the bed die as shaping front face of wheel moulding, be then often counted as
Form one of principal element of these defects.Shown by substantial amounts of production practices, it is preceding when the temperature drift of bed die cavity surface
The open defect stated substantial amounts of will occur；And after working as skin temperature reduction, problem will have obvious improvement.Therefore, how
The temperature of effective control bed die, to form uniform and stable temperature field, strengthens feeding when casting solidification shapes, for eliminating
The defects such as surface smart car hickie, segregation, pin hole are highly important.
The content of the invention
The purpose of this utility model is to provide a kind of improved low pressure casting wheel bed die, and the bed die can lift front face of wheel
Forming quality, solves the defects such as hickie, segregation, pin hole that smart car product easily occurs.
The technical solution of the utility model is：A kind of wheel die bed die, the region of bed die mold cavity surface correspondence spoke sets
Put grid lines, grid lines is divided into radially and circumferentially two kinds, depth 0.5mm-1mm, radial grid line is with circumferential grid lines angle
Obtuse angle, interval 3-5mm is evenly arranged.On bed die back of the body chamber surface, sawtooth pattern annular groove, radially even distribution are set；Cooling duct cloth
Put in bed die back of the body chamber, exhaust vent, exhaust vent direction back of the body chamber surface sawtooth pattern annular groove are set on airduct.
The utility model improves the fluid ability of aluminium liquid by the region processing grid lines in bed die correspondence spoke, makes
Filling type becomes more smooth, and feeding capacity is strengthened；Grid lines is conducive to the discharge of type intracavity gas, reduces the oxidation of aluminium liquid volume gas
And the probability of occurrence of bleb, pin hole；The significant area of dissipation for increasing mould, can accelerate the solidification speed of cast product surface layer
Degree, eliminates segregation, the white spot defect of cast(ing) surface；In bed die back of the body chamber processing annular groove, and a number of ring air cooling is equipped with,
Make the Temperature Distribution on whole bed die surface more uniform reasonable, form good consecutive solidification thermograde, be further ensured that
The high-quality shaping of casting.

Specific embodiment
As shown in Figure 1 and Figure 2, a kind of wheel die bed die, the spoke region mold cavity surface for corresponding to wheel in bed die 1 sets
Put grid lines 11, grid lines 11 includes radially and circumferentially two kinds, depth 0.5-1mm, radial grid line 11 and circumferential grid lines 11
Angle is obtuse angle, and 3-5mm is spaced between grid lines in the same direction 11, is evenly arranged.Grid lines 11 is processed using machine engraving, to ensure essence
Degree, it is to avoid viscous aluminium problem occurs.
The back of the body of bed die 1 chamber surface is uniformly arranged sawtooth pattern annular groove 12, and annular groove 12 is radially uniform, is spaced 5-10mm, depth 3-
6mm, 60-90 ° of the angle of annular groove cross section sawtooth.
3-5 groups cooling duct 5 is arranged in the back of the body chamber of bed die 1, along the radially fixed installation of spoke.Exhaust vent is set on airduct 5
51, the annular groove 12 in the axis direction back of the body chamber of exhaust vent 51；The air outlet angle of exhaust vent 51 is set to 60 ° -120 °.
The utility model simple structure, by processing bed die surface mesh ruling, improves the mold-filling capacity of aluminium liquid, enhances
The exhaust effect of die cavity, increases the area of dissipation of aluminium liquid, so as to effectively solve smart car product surface hickie, segregation, pin
The casting flaws such as hole；Process annular groove and be equipped with ring air cooling in bed die back of the body chamber, make the Temperature Distribution of whole bed die more uniform, flat
Weighing apparatus, stabilization, it is ensured that the excellent appearance forming quality of wheel casting, improve the integrated yield and the performance of enterprises of product.
