Description
Technical field
The utility model is related to field of machining, more particularly to a kind of equipment of lost foam casting.
Background technology
Lost foam casting is new casting technique with fastest developing speed at present, and its technique includes：In advance by molding sand in sandbox middle berth
Bottom, evaporative pattern is buried case, vibration molding, film laying and is vacuumized, is poured molten iron in the die cavity of evaporative pattern at the top of the sandbox,
Molding sand is poured out taking-up casting by mould turnover after evaporative pattern gasification, casting shaping.Main equipment is sandbox, for shape is not advised in sandbox
Molding sand then.But the defect existing for this equipment is, can there is burr or rough in cast(ing) surface, will cast
Part treats that it is cooled down completely after taking out, recycle cutter or other polishings to process casting, complexity casting treatment process.
Utility model content
The utility model is intended to provide a kind of equipment of lost foam casting, to solve surface smoothness after workpiece casting
It is not high, in addition it is also necessary to the problem processed again to its surface using cutter.
To reach above-mentioned purpose, base case of the present utility model is as follows：The equipment of lost foam casting, including sandbox, its
It is characterised by, the sandbox outer bottom is connected with pillar, and elastic component is connected between the pillar and sandbox, and sandbox is provided with
Oscillator, is rotatably connected to rotating shaft in the sandbox, rotating disk is fixedly connected with the rotating shaft, and spherical is provided with the sandbox
The molding sand of grain, sandbox side wall is provided with the first discharging opening, and the discharge outlet is provided with the first door close.
The principle and advantage of this programme be：
1st, rotating disk has been additionally arranged at the bottom of by sandbox in this programme, after casting is molded, using driven by rotary disc rotating disk top
Spherical molding sand, molding sand just starts work of polishing to cast(ing) surface, because the temperature in sandbox is also in higher state, so casting
Part has preferable thermoplasticity, by molding sand in the motion of cast(ing) surface, the rough place of casting progressively is adjusted into uniform,
Finally make cast(ing) surface smooth, to change also need to the step of cold treatment is carried out to casting in traditional handicraft in this way
（After i.e. casting is cooled down completely, cutter or other polishing casting are recycled to polish flat casting）.
2nd, the molding sand that tradition there are corner angle is designed to the smooth spherical molding sand in surface in this programme, it is intended that if
Using the molding sand for having corner angle, when it is that cast(ing) surface produces mutually motion, molding sand corner angle can leave cut in cast(ing) surface, because
The smooth spherical molding sand in surface is employed in this this programme to solve the above problems.
Preferred scheme 1：Based on scheme improvement, the sandbox be located at the first discharging opening side be provided with molding sand collection
Case, the molding sand collecting box lower section is fixedly connected with reciprocating transmission device.Its effect is, after casting shaping, opens first and goes out
Material mouth, sandbox Sand is just dropped into from the first discharging opening and stored in molding sand collecting box, when using next time, by reciprocal
Transmission device drives molding sand collecting box to move up, until that higher than sandbox, just molding sand collecting box Sand can be poured into sandbox
In reused.Avoid and casting is taken out after sandbox pours out molding sand, it is necessary to overturn in conventional art, then molding sand is refunded
To in sandbox.
Preferred scheme 2：Preferably 1 improvement, the molding sand collecting box offers second near the side of sandbox
Discharging opening, the second discharging opening bottom level is rotatably connected to the second door close, and second door close offsets with sandbox, makes
Two door closes are closed under normal conditions.Its effect is that, when molding sand collecting box is pushed to sandbox top, second closes
Door is closed without the support of sandbox, is just rotated down so as to open the second discharging opening, molding sand is just dropped into from molding sand collecting box
In sandbox, the operating procedure for so making molding sand back and forth utilize more is automated and simplified,
Preferred scheme 3：Based on scheme or preferred scheme 2 improvement, first door close is rotatably connected on discharging
Mouthful lower section, its effect is：When the first door close is opened, while the first door close rotates down the first discharging opening of opening
The bridge of molding sand collecting box can be entered into as molding sand, it is to avoid molding sand is scattered everywhere.
Preferred scheme 4：Preferably 3 improvement, the disk upper surface is rotatably connected to steel ball, the steel of the rotation
Ball can be played and play booster action to cast(ing) surface polishing.
Brief description of the drawings
Fig. 1 is the structural representation of the apparatus embodiments of the utility model lost foam casting.
Fig. 2 is the operating diagram of the equipment of the utility model lost foam casting.
Specific embodiment
The utility model is described in further detail below by specific embodiment：
Reference in Figure of description includes：Sandbox 1, pillar 2, oscillator 3, rotating shaft 4, rotating disk 5, the first door close
6th, molding sand collecting box 7, hydraulic cylinder 8, the second door close 9, evaporative pattern 10.
Embodiment is basic as shown in accompanying drawing 1, Fig. 2：The equipment of lost foam casting, including sandbox 1, the outer bottom of the sandbox 1
4 angles be respectively connected with pillar 2, spring is connected between pillar 2 and sandbox 1, and the bottom of sandbox 1 is installed with oscillator 3.
Rotating shaft 4 is rotatably connected in sandbox 1, the rotating shaft 4 is driven by motor, the upper end of rotating shaft 4 is fixedly connected with rotating disk 5, the inside of sandbox 1 dress
