Description
Technical field
The present invention relates to casting industry equipment technical field, relates in particular to a kind of casting sand and is automatically separated with shot
Retracting device.
Background technology
Casting technique can be divided into gravitational casting, compression casting and sand casting.The adaptability of sand casting is very wide, due to sand
Modeling Material used in mold casting is cheap and easy to get, and Casting mold manufacturing is easy, and price advantage is especially prominent, single-piece production to casting,
Produce by batch and largely produce and adapt to, be always the basic technology in Foundry Production for a long time.At present, in whole castings
In part production, 60~70% casting is produced with sand mold.
Sand casting uses the Modeling Material based on sand, and each sand mold is used only once, and in a large amount of productions, to give birth to
Thousands of individual identical casting are produced, it is necessary to make same amount of sand mold, so low productivity ratio is difficult to meet the needs of production,
But also a series of problems can be brought, as Modeling Material consumption is big, molding sand can produce dust, pollute environment, deteriorate work bar
Part is, it is necessary to the processing of complete molding sand and transporting equipment；Scab defect is easily produced after cast, influences surface finish of casting etc..Such as
Fruit is cooked Modeling Material using the quartz sand or shot of binder free, and the work of binding agent is replaced by gravity, negative pressure, magnetic field force
With, such Modeling Material then can Reusability, without sand preparing machine, also there occurs basic change for formative method.
After the completion of pouring technology in casting process, into the knockout handling process of casting.Knockout be divided into artificial knockout and
Mechanical knockout, in non_mechanical foundry shop, casting is poured into a mould on ground, and usually in cast place, knockout, worker use big on the spot
Hammer and drill rod hit sandbox and disclose molding sand, also have and coordinate aforesaid operations to carry out knockout using pneumatic shovel；Conditional workshop can adopt
Row knockout is lifted up into pneumatic knockout hook or vibrating shakeout is hung, knockout working condition is poor on the spot, productivity ratio is low, is only applicable to unit
The foundry of small lot production, on mechanical production line, knockout is concentrated in generally use mechanization, and casting need to be placed on to vibrations
Sand is set to fall by vibrations on shakeout.
But traditional mechanical knockout, it is only applicable to do the casting of Modeling Material using molding sand.And other improved castings
Technique, such as during sand casting add magnetic shot moulding when, traditional mechanical shakeout machinery be unfavorable for molding sand and
The separation and recycling of shot.
The content of the invention
The problem of the invention aims to overcome prior art to exist, there is provided one kind can solve the problem that novel casting technique
Middle casting sand is automatically separated retracting device with shot, improves production efficiency, reduces the labor intensity of worker.
The technical solution adopted by the present invention：Casting sand is automatically separated retracting device with shot, and frame is arranged on ground,
It is characterized in that：Spring is uniformly arranged in the frame, screen frame is packed on spring, is fixed with screen cloth on screen frame, under screen frame
Hopper is connected to, hopper is connected with split tunnel by flexible pipe, and hopper both sides are separately installed with vibrating motor, split tunnel
One wing passage is connected on molding sand elevator passage, and another wing passage of split tunnel is connected on shot elevator passage；It is described
Split tunnel sets molding sand material respectively with molding sand elevator passage connector, split tunnel and shot elevator passage connector
Door, shot bin gate；Electromagnet is provided with the inside of the split tunnel.
The spring being uniformly arranged in the frame is 3 or more than 3.
The beneficial effects of the present invention are：
1st, the present invention eliminates manual operation, improved due to using motor driven screen frame and screen mechanical vibrating shakeout mode
Production efficiency, reduce the labor intensity of worker.
2nd, the present invention using separable molding sand and shot by the way of, pass through in the split tunnel of screen frame hopper set electricity
Magnet, by split tunnel be respectively communicated with molding sand elevator and with two passages of shot elevator, and by distinguishing in two passages
Bin gate is set, effectively realizes the separation of molding sand and shot, and recycling, production cost is reduced for enterprise, improves
Economic benefit.
Brief description of the drawings
Fig. 1 is that a kind of casting sand of the present invention is automatically separated retracting device structural representation with shot.
Fig. 2 is that a kind of casting sand of the present invention is automatically separated retracting device structure left view with shot.
Screen frame 1, spring 2, frame 3, hopper 4, vibrating motor 5, flexible pipe 6, split tunnel 7, electromagnet 8, molding sand lifting
Machine 9, shot elevator 10, ground 11, molding sand bin gate 12, shot bin gate 13, screen cloth 14.
Embodiment
The invention will be further described with reference to the accompanying drawings and examples.
As shown in Figure 1, 2, a kind of casting sand is automatically separated retracting device with shot, and frame 3 is placed on ground 11, machine
The spring 2 being uniformly arranged on frame 3 is at least more than 3, or 3, and both sides dispose 2 each 6, spring in frame 3, and screen frame 1 is fixedly mounted with
On the spring 2 of frame 3, screen cloth 14 is fixed with screen frame 1, hopper 4 is connected under screen frame 3, the both sides of hopper 4 install one respectively
Individual vibrating motor 5, hopper 4 and split tunnel 7 are connected by flexible pipe 6, and the wing passage of split tunnel 7 one is connected to molding sand elevator
On 9 passages, 7 another wing passage of split tunnel is connected on the passage of shot elevator 10, and split tunnel 7 is logical with molding sand elevator 9
Road connector is mounted with molding sand bin gate 13, and split tunnel 7 is mounted with shot bin gate 13 with the passage connector of shot elevator 10, point
The inner side of passage 7 is provided with electromagnet 8.
Casting after being cooled down in casting technique is placed on the screen frame 1 in device, is switched on power, vibrating motor 5 vibrates, entirely
Retracting device start-up operation is automatically separated, under the effect of vibration of vibrating motor 5, molding sand and shot are shaken off from casting, from sieve
The screen cloth 14 of frame 1 drops into hopper 4, is entered through hopper 4 in split tunnel 7.Now, the shot of the side of split tunnel 7
The passage shot bin gate 13 of elevator 10 is closed, and the passage molding sand bin gate 12 of molding sand elevator 9 of the opposite side of split tunnel 7 is opened,
Molding sand directly enters in molding sand elevator 9 from the passage of split tunnel opposite side, and shot is all adsorbed on electromagnet 8.When
Molding sand closes vibrating motor 5 and electromagnet 8 after all shot has all been shaken off, and opens the iron that split tunnel is equipped with electromagnet side
The shot bin gate 13 of ball elevator 10, shot are then entirely fallen in elevator 10, and the whole process that separates and recovers is completed.
