Description
Technical field
The utility model is related to a kind of external pouring gate structure.
Background technology
Existing pouring gate structure design is unreasonable, in casting, and the bits, sand in molten iron, molten steel are easily involved in, and influence
The surface quality of casting, with larger limitation.
Utility model content
In view of the deficiencies in the prior art, technical problem to be solved in the utility model is to provide a kind of external running channel knot
Structure, not only reasonable in design, and efficiently convenient.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is：A kind of external pouring gate structure, including set
Sprue cup is fixedly connected with the top of main running channel outside mold cavity, the main running channel, the main running channel bottom is connected to type
Chamber, the two ends of the main running channel are big, middle part is small, in Double-horn type, and the main running channel is provided with close to a big end of sprue cup
Pushing off the slag net, the main running channel is sequentially set with some pushing off the slag teeth, the master close to another big end of die cavity along running channel wall direction
The middle part of running channel is wrapped with muff with the big end close to die cavity.
It is preferred that, the main running channel is L-shaped, and the two ends angle of the main running channel is 90 degree ~ 135 degree.
It is preferred that, the pushing off the slag tooth is obliquely installed, and the setting direction of the pushing off the slag tooth is opposite with feedstock direction.
It is preferred that, the pushing off the slag tooth gradually increases from main running channel toward die cavity direction.
It is preferred that, the muff is made up of low Heat Conduction Material.
Compared with prior art, the utility model has the advantages that：The utility model reasonable in design, favorably
In taking out the bits in molten iron, molten steel, sand, beneficial to the surface quality for improving casting, have broad application prospects.
The utility model is described in more detail with reference to the accompanying drawings and detailed description.
Brief description of the drawings
Fig. 1 is the organigram of the utility model embodiment.
In figure：The main running channels of 1-, 2- sprue cups, 3- pushing off the slag nets, 4- pushing off the slag teeth, 5- muffs.
Embodiment
For features described above of the present utility model and advantage can be become apparent, special embodiment below, and coordinate accompanying drawing,
It is described in detail below.
As shown in figure 1, in order to solve the above-mentioned technical problem, the technical solution of the utility model is：A kind of external running channel knot
Structure, including the main running channel 1 being arranged on outside mold cavity, the top of the main running channel 1 are fixedly connected with sprue cup 2, and the master pours
The bottom of road 1 is connected to die cavity, and the two ends of the main running channel 1 are big, middle part is small, in Double-horn type, and the main running channel 1 is close to sprue cup
A 2 big end is provided with pushing off the slag net 3, and the main running channel 1 is set close to another big end of die cavity along running channel wall direction order
There are some pushing off the slag teeth 4, the middle part of the main running channel 1 is wrapped with muff 5 with the big end close to die cavity, is prevented effectively from casting
Molten iron or molten steel front end solidify in advance；In casting, molten iron or molten steel first pass through pushing off the slag net 3, remove the impurity of a part, connect
Because big end a to middle part of main running channel 1 has a gradient, molten iron or molten steel by way of when, moment is full of, and is conducive to bits, gas
The impurity such as body, sand float, and then molten iron or molten steel enter another big end after middle part accelerates, and the impurity of big weight is kept off
Slag tooth 4 is retained, and is filtered layer by layer, efficiently convenient；Other main running channel 1 is arranged on the size for being conducive to reducing mould outside mold cavity,
Substantially reduce production cost.
In the utility model embodiment, the main running channel 1 gradually increases from middle part toward the direction of sprue cup 2, and gradient is 5 degree
~ 15 degree, the main running channel 1 gradually increases from middle part toward die cavity direction, and gradient is 5 degree ~ 15 degree.
In the utility model embodiment, the main running channel 1 is L-shaped, and the two ends angle of the main running channel 1 is 90 degree ~ 135
Degree.
In the utility model embodiment, the pushing off the slag tooth 4 is obliquely installed, the setting direction of the pushing off the slag tooth 4 and charging
In the opposite direction.
In the utility model embodiment, the pushing off the slag tooth 4 gradually increases from main running channel 1 toward die cavity direction.
In the utility model embodiment, the muff 5 is made up of low Heat Conduction Material, such as foamed plastics.
The utility model is not limited to above-mentioned preferred forms, and anyone can obtain under enlightenment of the present utility model
Go out other various forms of external pouring gate structures.All impartial changes done according to present utility model application the scope of the claims and modification,
Covering scope of the present utility model should all be belonged to.
