Product Description

Brass Gravity Die Casting Machine / Metal Die Casting Machine With 20mm Travel Stroke



1. Mechanical structure and working principle


1) Pedestal frame


Pedestal frame is located at the bottom of the machine. It was used to store water and graphite powder to cool and dip coating the dies. Thus the machine can operate for a long time and die temperature is under control. Left and right water tank are separated, which make them easy to clean and can blend the water and graphite powder evenly. Considering the strong causticity of graphite,the water tank is welded by stainless steel sheet to prolong its useful time. Agitation effect is good and there is no dead angle.


  2) Support cantilever


Support cantilever consists of bottom beam, support rotation axis, axis seat and adjustment of casting angle. Die opening and closing, overturn, rise-fall of left and right model matching racks is completed by the support cantilever


  3) Hydra Tank


Hydraulic tank is installed between the electric cabinet and oil pump. It is the drive of hydraulic pressure part of the whole machine used to reclaim hydraulic oil and cool the heat produced during the motion of hydraulic pipeline.


  4) Hydraulic station and drive assembly


Hydraulic station and drive assembly are combined by hydraulic system, including motor, oil pump, electromagnetic reversing valve, electromagnetic flow valve, manual pressure regulating valve, pipeline throttle valve and oil cylinder. It is in charge of oil supply, pressure adjustment, oil reclaim and actions of each oil cylinder.

Rise and fall---die opening----die matching----overturn----die dipping in revolution----push out the clean die----rotation and casting will be carried out one by one


5) Electrical control system


Electrical control system mainly adopts the original binding electrical components of Japan Mitsubishi Ohm Dragon, including: PLC, touch screen, transformer, current transformator, voltmeter, ammeter, revolving switch, emergency stop switch, AC contactor, heat relay, air switch(380V/220V), photoelectric sensor, control box(manual/automatic), rotation, die opening and closing, model cleaning, overturn, rise and fall, overturn emergency stop. All actions will be carried out with the operation control system.


6) Left and right agitation electric motor assembly


Left and right agitation electric motor assembly is located at both sides of hydro cylinder. It consists of electric motor agitation long axis, stainless steel turbine, bearing holder support, electric motor seat, dust-proof flange and air-proof nut. It blends the water and graphite powder evenly to prevent deposition. It can also blend precipitated graphite powder with water by agitation.


7) Left and right die matching support rack


Left and right die matching support rack consists of bracket copper sheathing, lead rail, soldering cup, oil tank for die opening and closing, left and right boxes, left and right oil tanks for die cleaning, left and right die connection rack. This part carries out raising, matching, cleaning of the die and revolving casting, etc


8) Left and right revolving boxes and die cleaning mechanism: 


Left and right revolving boxes and die cleaning mechanism mainly consist of bearing, gear, gear shaft, hydro cylinder, positive stop, up and down shaft block, sealing element, induction block, flange, etc. It is mainly in charge of die cleaning; die dipping in rotation, front casting, and die replacement.


2. Working procedure


1) HZ-450 Gravity Die Casting Machine is designed to be manual mode and automatic mode.

M    anual: controlled by a single switch

Automatic: die clamping with pedal and hands (hands-clamping is designed specifically for worker’s safe operation.)

2) Take direct casting as example: Raise to set angle, put down core sand and tread the pedal switch (die matched) ---casting---tread pedal switch for a time---begin timing when worktable fall to original place---the die will open automatically when time is over---take out products---tread switch for a time ---worktable will overturn--- die rotates---die falls and rotates and cooling---die rises again---worktable turns back to original place--- worktable rises
