Description
Technical field
The present invention relates to a kind of casting mould, specifically for the processing and forming of aluminium alloy wheel hub.
Background technology
Current automotive hub profile is big, and the degree of depth is deep, and median pore radius is big, structure circular symmetry, and two ends have inserts, casting strength and appearance requirement the highest, therefore, castings desire pore-free and be not allow for the defects such as loose and crackle, and yield is big.Needed for using traditional side gate or connor gate, injection ratio pressure is relatively big, and upper and lower Spoke Strength is inconsistent, and the cast gate of residual affects outward appearance.
Summary of the invention
The technical problem to be solved is for above-mentioned deficiency of the prior art, disclose a kind of aluminium alloy wheel hub die casting, it uses center feed system, not only reduces die shape, and foundry goods all achieves good effect at aspects such as filling type, intensity and outward appearance.
In order to achieve the above object, the present invention is achieved by the following technical solutions:
A kind of aluminium alloy wheel hub die casting disclosed by the invention, including top clamping plate, taper pin, cover half cage plate, installing plate, slide block, dynamic model cage plate, Bottom clamp plate, ejector pin retaining plate, dynamic model small-sized core, spreader, ejector sleeve, push pedal, cushion block, moving die insert, panel, guide pin bushing, fixed die insert, cover half charging aperture insert, guide pillar, ingate insert, sprue bush and arm-tie；nullDescribed sprue bush is fixedly mounted in the installing hole of top clamping plate，Described guide pillar upper end is arranged on top clamping plate，Guide pillar lower end is arranged in the installing hole of installing plate by guide pin bushing，It is arranged on bottom guide pillar in the installing hole of dynamic model cage plate，Described cover half cage plate is arranged on the end face of installing plate，Described cover half charging aperture insert is arranged in the installing hole of cover half cage plate，Described arm-tie upper end is arranged on top clamping plate，Arm-tie lower end is arranged on dynamic model cage plate，Described panel is arranged on arm-tie，Described cushion block is fixedly mounted on Bottom clamp plate，Described dynamic model cage plate is arranged on the end face of cushion block，Described installing plate is arranged on the end face of dynamic model cage plate，Described dynamic model small-sized core lower end is arranged on Bottom clamp plate，Dynamic model small-sized core upper end is arranged in the installing hole of dynamic model cage plate by ejector sleeve，Dynamic model small-sized core top is arranged in the installing hole of moving die insert，Described push pedal is arranged on dynamic model small-sized core and push pedal is positioned at cushion block，Described ejector pin retaining plate is arranged on dynamic model small-sized core and ejector pin retaining plate is positioned at the top of push pedal，Described moving die insert is arranged in the groove of dynamic model cage plate，Described spreader is arranged in the center mounting hole of moving die insert，Described slide block is arranged on the top of moving die insert，Described fixed die insert is arranged on the top of slide block and fixed die insert is positioned in the groove of installing plate，Described ingate insert is arranged in the installing hole of fixed die insert，Described taper pin is arranged in the installing hole of installing plate and taper pin is by the installing hole of slide block and the installing hole of dynamic model cage plate.
The preferred embodiment of the present invention and further improvement are as follows:
(1) described sprue bush centrage differs 25mm with described cover half charging insert centrage.
(2) described spreader is for the spreader that charging is divided into three strands.
(3) distance between upper surface and the upper surface of ingate of described sprue bush is D, and 0 ＜ D≤10mm.
(4) distance of separation between described top clamping plate and cover half cage plate is L, and 100mm≤L≤120mm；The thickness of described top clamping plate is more than 100mm.
(5) a length of 15 in dynamic model cage plate stayed by described guide pillar～20mm.
Further: the distance between described top clamping plate and cover half cage plate is 120mm.
(6) slider core uses dovetail groove to fix；The slip side of described slider core makes the oblique angle having 3 degree.
The medicine have the advantages that
On the whole, the present invention uses taper pin band movable slider to extract out, has both reduced die cost, and the mould features compact structure；
The slip side of the slider core of the present invention is made 3 ° of oblique angles, to avoid the stuck slide block because expanding with heat and contract with cold；Use center feed system, not only reduce die shape, and foundry goods all achieves good effect at aspects such as filling type, intensity and outward appearance；
Concrete, owing to die cavity is deep and complicated, the present invention uses central feeding, and metal flow process is short, is evenly distributed, and fills type smooth, and aerofluxus is good.For avoiding molten metal to flow into die cavity too early, sprue bush center feeds the low 25mm in insert center than cover half；Charging ingate is divided into 3 bursts of chargings, will not break material handle, make material handle remain in cover half during twice-die-opening, in order to remove.During die sinking, there is part package power due in dynamic, cover half, therefore first top clamping plate separates with cover half cage plate, i.e. the 1st time die sinking.When, after die sinking to arm-tie active position, dynamic, cover half body separates, i.e. the 2nd time die sinking.In view of die sinking distance and be easy to take out smoothly stub bar, top clamping plate and cover half cage plate distance of separation control mm within 120.Top clamping plate THICKNESS CONTROL is at more than 100mm, to ensure that the length of end fixed by guide pillar.Guide pillar should suitably overstriking, lengthening, before dynamic, cover half body separate, guide pillar also has longer one section and stays in dynamic model cage plate, can prevent part torsional deformation and ensure that slide block is steadily extracted out.Use taper pin band movable slider to extract out, both reduce die cost, and the mould features compact structure.Slider core uses dovetail groove to fix, and can bear bigger Core-pulling force, and easy to process.
