Abstract
A kind of more de-gating process of aluminum-alloy wheel low pressure casting and its device.Molten aluminum is set to be initially entered from inner rim in the more cast gates of wheel inner rim end set using more cast gate pouring types, after the mold cavity of rim full of after molten aluminum, molten aluminum enters from trumpet assembly simultaneously again, after molten aluminum full of starting pressurization, cooling after mold cavity.When cooling; the wheel outer rim position finally filled since molten aluminum; start side modular ring shape water cooling; due to cooling technique be from outer rim solidify, and wheel rim and wheel rim position direction consecutive solidification simultaneously substantially reduces the crystallization and freezing time of wheel rim and spoke position casting; while improving the production efficiency; cast-internal dense structure degree is improved again, and material mechanical performance is good, and the elongation percentage of especially spoke is largely increased.
Description
Technical field
A kind of aluminum-alloy wheel low pressure casting pouring technology of present invention offer and its device.
Background technology
Currently, traditional aluminum-alloy wheel low pressure casting mostly uses the process of center rising pouring.Molten aluminum passes through center
Cast gate enters mold cavity, flows transversely across wheel spoke position rear steering and vertically fills wheel rim position, until filling type completion.It is tying
During crystal solidification, wheel rim is in the distal end far from trumpet assembly, starts to solidify at first, so need the preferential feeding in spoke position
Wheel rim postpones spoke position crystallization and freezing opportunity, influences aluminum-alloy wheel material mechanical performance, the especially extension at spoke position
Rate is generally relatively low, directly influences the total quality of wheel.
Invention content
It is an object of the invention to make up the deficiencies in the prior art, aluminum-alloy wheel quality is improved, provides a kind of aluminium conjunction
Golden wheel pressure casting technique and device improve wheel spoke elongation percentage for emphasis, while improving casting production efficiency.
The technical solution adopted by the present invention is：A kind of more de-gating process of aluminum-alloy wheel low pressure casting, casting technique use
More cast gate pouring types make molten aluminum be initially entered from inner rim, wait for rim in the more cast gates of wheel inner rim end set
After mold cavity is full of molten aluminum, molten aluminum enters from trumpet assembly simultaneously again, after molten aluminum full of starting pressurization, cold after mold cavity
But.
When cooling, the wheel outer rim position finally filled since molten aluminum, start side modular ring shape water cooling, and water cooling is located at
Have a common boundary thick big position close to the spoke and wheel rim of outer rim, backform cooling equally using annular water cooling, water cooling be located at spoke just on
The backform of side, backform center is using point cooling by water trumpet assembly.
By the control to cooling time and flow, the molten aluminum in cavity is crystallized with the cooling sequencing of mold,
Crystallization is carried out to wheel rim and spoke direction simultaneously from outer rim, until inner rim and core wheel position finally solidify, completes entire casting
Make process.
In the low pressure casting process, wheel casting spoke and outer rim are face-up, and wheel rim and inner rim position exist
Lower part.
The more cast gates of the inner rim are arranged immediately below inner rim, and gate shape is circle, and the quantity of cast gate according to
It is different according to wheel size, quantity at least eight.
The trumpet assembly is arranged immediately below core wheel, and gate shape is circle.
The side modular ring shape water cooling, backform annular water cooling, apart from cast(ing) surface distance 15-40mm, the cooling
Water flow is 150-400L/hr.
A kind of aluminum-alloy wheel low-pressure casting apparatus, including cooling forming mold system, pressure pouring system, casting device
Including more valve gated molds, lower section communicates with pouring basin and is securely fitted on board platen, is low-voltage temperature-keeping stove below machine bench,
Molten aluminum links pouring basin central inlet position by stalk in stove.
The upper mold of the low pressure casting die, the hydraulic control system of Bian Mo and board link, and casting is equipped in upper mold
The ejecting mechanism of demoulding.
The pouring basin and mold junction are arranged multiple cast gates, and there are one the cast gates of ceramic material at each cast gate
Set, for last crystallization and freezing at the cast gate in feeding stage of pressurizeing after aluminum liquid filling type.
Since multiple small cast gates are arranged in the present invention below wheel inner rim, while one trumpet assembly is set in core wheel,
So molten aluminum loading time shortens half, improves and fill type production efficiency；Due to cooling technique be from outer rim solidify,
And wheel rim and wheel rim position direction consecutive solidification simultaneously, the crystallization and freezing time of wheel rim and spoke position casting is substantially reduced,
Cast-internal dense structure degree is improved, material mechanical performance is good, and the elongation percentage of especially spoke is largely increased；Meanwhile it is whole
A casting device equipment is simple, and a pouring basin, entire technical process are increased on the basis of pressure common central cast is cast
Simply, easy to operate.
Description of the drawings
The present invention is further described with example below in conjunction with the accompanying drawings.
Fig. 1 is the more de-gating process casting schematic diagrames of low pressure of the present invention.
Specific implementation mode
In Fig. 1, the more de-gating process devices of aluminum-alloy wheel low pressure casting of the present invention include mainly mold cooling system
System and pressure pouring system, casting mould includes lower die（2）, upper mold（4）, Bian Mo（3）, casting knock-pin（8）, whole set of die sets
In pouring basin（1）On, between pass through multiple sprue bush（11）Unicom mold cavity and pouring basin, pouring basin are assemblied in low pressure casting
Host board platen（12）On, between be equipped with stalk（13）Unicom holding furnace（14）Interior molten aluminum is made by stalk in pressure
Entered in pouring basin with lower, is then entering mold cavity by sprue bush.
The mold cooling system includes side modular ring shape water cooling（9）With（10）, upper die annular water cooling（6）With（7）With in
Heart spreader water cooling（5）, quickly start side mold annular water cooling, the casting from outer rim after molten aluminum is completely filled with mold cavity
Start crystallization and freezing, open upper die annular water cooling and central point water cooling successively, until casting completes consecutive solidification.
