Abstract
The present invention relates to wheel hub manufacturing technology fields, and in particular to a kind of aluminium alloy wheel hub core pulling casting mould and its technique.Include lower die, Bian Mo and the upper mold that wheel hub casting mold cavity is formed after combination, the arbitrary neighborhood both sides of the chest window of the lower die is equipped with insert between facing upward inclined-plane, and the arc-shaped structure of insert matches with molding wheel hub C ring medial surfaces just.The present invention in the lower die of wheel hub by being arranged insert, the aluminium newly increased in C rings in the prior art is replaced with insert, ensure that demoulding angle, it is conveniently stripped while, alleviate the weight about 5.3kg of wheel hub unsawn timber, both the aluminium for having saved cast blank has saved cost, and reduces the damage of process tool, meet lightweight, the personalized market demand simultaneously, there is excellent market value and economic benefit.
Description
Technical field
The present invention relates to wheel hub manufacturing technology fields, and in particular to a kind of aluminium alloy wheel hub core pulling casting mould and its work
Skill.
Background technology
A kind of wheel hub for the special-shaped tread ring now developed（Referring to attached drawing 1）, the gas nozzle of this wheel hub is mounted on B, C ring corner
Place, and the gas nozzle of existing wheel hub is in D ring rib windows.According to existing casting technique, tread ring needs to take off according to certain in wheel rim
Modular angle degree could realize smooth demoulding, and this wheel hub C ring portions position protrudes upper mold, and when casting can not achieve demoulding, be taken off to realize
Mould can only increase the aluminium at wheel rim C rings, keep its position consistent with B ring angles and connect it is suitable, then to increased material when passing through processing
Material carries out turning, processes required moulding.However, planar defect in the presence of existing this casting technique：First, when casting
Local material is blocked up, is also easy to produce the casting sex chromosome mosaicism such as shrinkage cavity, loose；Second, vehicle bits amount is big when processing, waste of material is more.
Invention content
In view of the deficiencies of the prior art, the present invention provides a kind of aluminium alloy wheel hub core pulling casting mould and its techniques.
Technical scheme is as follows：
A kind of aluminium alloy wheel hub core pulling casting mould, including lower die, Bian Mo and the upper mold of wheel hub casting mold cavity, institute are formed after combination
The arbitrary neighborhood both sides of the chest window for stating lower die is faced upward and is equipped with insert between inclined-plane, the arc-shaped structure of insert, just with molding wheel hub C
Ring medial surface matches.
A kind of aluminium alloy wheel hub core pulling casting technique, the casting technique include：Early period is cast, by preheated a set of insert
It is positioned over lower die corresponding position, then molding starts to cast；Ejection phase：When die sinking, insert is taken up with wheel hub by upper mold,
Insert is removed again after demoulding, does next cycle, while preheated another set of insert is put into lower die corresponding position.
A set of insert includes five inserts, and a set of wheel hub core pulling casting mould is equipped with 2-3 and covers insert.
The beneficial effects of the present invention are：By the way that insert is arranged in the lower die of wheel hub, C in the prior art is replaced with insert
The aluminium newly increased in ring, ensure that demoulding angle, it is conveniently stripped while, alleviate the weight of wheel hub unsawn timber about
5.3kg had both saved the aluminium of cast blank, had saved cost, and reduced the damage of process tool, while meeting light weight
Change, the personalized market demand, there is excellent market value and economic benefit.
Description of the drawings
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is the structural schematic diagram of aluminium alloy wheel hub of the present invention.
Fig. 2 is the structural schematic diagram of aluminium alloy wheel hub core pulling casting mould of the present invention.
Fig. 3 is the overlooking structure diagram of lower die.
Wherein：1, upper mold；2, wheel hub cavity；3, insert；4, Bian Mo；5, lower die；6, rib window faces upward inclined-plane.
Specific implementation mode
The invention will now be described in further detail with reference to the accompanying drawings.
Refering to fig. 1 to Fig. 3, a kind of aluminium alloy wheel hub core pulling casting mould, including wheel hub casting mold cavity is formed after combination
Lower die 5, side mould 4 and upper mold 1, the arbitrary neighborhood both sides of the chest window of the lower die 5 are equipped with insert 3 between facing upward inclined-plane 6, and the insert 3 is in
Arcuate structure matches with molding wheel hub C ring medial surfaces just.
A kind of aluminium alloy wheel hub core pulling casting technique, the casting technique include：Early period is cast, by preheated a set of insert
3 are positioned over 5 corresponding position of lower die, and then molding starts to cast；Ejection phase：When die sinking, insert 3 is with wheel hub by upper mold 1
It takes up, again removes insert 3 after demoulding, do next cycle, while preheated another set of insert 3 is put into lower die 5 and is corresponded to
Position.
A set of insert 3 includes five inserts 3, and a set of wheel hub core pulling casting mould is equipped with 2-3 and covers insert 3.
Wherein：A, B, C, D distinguish A rings, B rings, C rings and the D rings of wheel hub in Fig. 1.
The foregoing description of the disclosed embodiments enables those skilled in the art to implement or use the present invention,
General Principle defined herein can be realized in other embodiments without departing from the spirit or scope of the present invention.
The scope of the present invention is limited by claim and its equivalent.
