Description
Technical field
The invention belongs to forklift hub casting technology field, and in particular to a kind of forklift hub extrusion casint device.
Background technology
Forklift hub is the important feature part about fork truck traffic safety, its quality and reliability be not only related to vehicle and
Passengers inside the car and the security of goods and materials, and also affect the property such as stationarity, maneuverability, comfortableness in vehicle travel process
Can, this requires the features such as wheel hub has good fatigue strength high, rigidity and elasticity, size and dimension high precision, light weight.
And existing forklift hub casting technique is mainly gravitational casting and die casting.Produced using gravity foundry technology and taken turns
Hub, has the advantages that manufacturing process is simple, ripe, production efficiency is high, small investment.But due to no applied force, in order to be caused
Close casting, generally requires to utilize riser feeding, so the dead head of gravity casting hub is larger, product yield is low.Using pressure
Casting process produce wheel hub, with speed of production it is fast, dimensional accuracy is high, the low advantage of surface roughness.But due to high-pressure jet volume
The gas that enters and it is mingled with Dispersed precipitate in casting, so die casting wheel hub can not improve intensity by being heat-treated, and elongation
It is low, poor reliability during use.
The content of the invention
It is an object of the invention to overcome above-mentioned the deficiencies in the prior art, there is provided a kind of forklift hub extrusion casint device.
A kind of forklift hub extrusion casint device, including side mould, upper mold core, lower mold core, liquid injection pipe, ejection block, it is described on
Core rod is arranged on the top of lower mold core, and upper mold core is bolted in the circular groove at upper bolster center, the top of upper bolster with
The end of the piston rod of hydraulic jack is connected, and hydraulic jack is fixed on upper fixed seat, and fixed seat is fixed on the top of column,
Be provided with side mould on the outside of upper mold core and lower mold core, the bottom of lower mold core is provided with manhole, the manhole of lower mold core bottom with
Liquid injection pipe is communicated, and ejection block is provided with liquid injection pipe, and ejection block is fixed on the end of the piston rod of cylinder, and cylinder is fixed by flange
In the bottom of liquid injection pipe, the middle part of liquid injection pipe is communicated by feed pipe with the bottom of metal bath.
Preferably, the lower mold core is bolted in the circular groove of die shoe center, and die shoe is fixed in column
Portion.
Preferably, the top of the metal bath is provided with air injection pipe.
Compared with prior art, beneficial effects of the present invention：
When in use, the metal bath in metal bath enters casting mold cavity to the present invention along feed pipe, liquid injection pipe, works as die cavity
When filling, moved in air cylinder driven ejection block, realize that completing extruding fills type and compression solidification, after solidification of metal melt, hydraulic jack
Drive and moved in upper bolster, upper mold core, open side mould, moved in the continuation of air cylinder driven ejection block, realize forklift hub casting blank
The demoulding, has the advantages that casting efficiency high, good product quality, to be easy to the demoulding, Product Precision high.
