Abstract
A kind of feeding head that there is collection slag to act on, it is arranged on casting boss position at the die joint of plane or at the die joint of casting square hole position baseplane, including drainage groove portion, feeding portion and transition region, the transition region connects the casting and upper edge is concordant with the die joint, the drainage groove portion is connected with the transition region and upper edge is concordant with the die joint, and the feeding portion is connected to the top of the drainage groove portion and width is identical with the drainage groove portion.There is the utility model drainage to lead slag function, realize feeding and the collection slag of casting process, effectively reduce and be mingled with and rarefaction defect, reached and reduced moulding and following process workload, the effect for improving cast properties homogeneity, can be used in the casting that there is local thick big boss or large scale square hole.
Description
Technical field
The utility model is related to metal casting moulding process, more particularly to a kind of feeding head that there is collection slag to act on,
Belong to casting technology field.
Background technology
The casting of thick big boss its boss position in molten iron cavity filling process is locally lain in be very easy to generation and be mingled with class to lack
Fall into, if boss position thermal center is larger also easily to produce loose class defect；It is to solve the above problems in actual casting production
Conventional method is to increase chill in heat energy-saving position, while plane increases allowance in the casting of boss.Similarly, for
The casting of large scale square hole is there are, the shaping mud core of square hole can hinder the Feeding channel of top iron liquid, while also counteracts that folder
The floating passage of debris, the solution generally used is also increase chill and allowance.
But there is following deficiency in use in above-mentioned technical proposal：
1. there is influence in the homogeneity of the more multipair cast properties of chill consumption, while adding moulding difficulty.
2. increase allowance adds the cost of post-production.
3. increase allowance can further increase the tendency for producing rarefaction defect equivalent to casting thermal center is increased.
Utility model content
In order to solve the above mentioned problem caused by prior art, the utility model provides a kind of feeding that there is collection slag to act on
Rising head, for existing in the casting of local thick big boss or large scale square hole, realizes feeding and collection slag function, reduction is mingled with and dredged
Loose defect, reaches and reduces moulding and following process workload, the effect for improving cast properties homogeneity.
The technical scheme in the invention for solving the technical problem is as follows：
A kind of feeding head that there is collection slag to act on, is arranged on casting boss position at the die joint of plane or casting
At the die joint of square hole position baseplane, including drainage groove portion, feeding portion and transition region, the transition region connect the casting and on
Edge is concordant with the die joint, and the drainage groove portion is connected with the transition region and upper edge is concordant with the die joint, described to mend
Contracting portion is connected to the top of the drainage groove portion and width is identical with the drainage groove portion.
Further, the length of described transition region is 2~4 times of thickness.
Further, the length of described transition region is more than 50mm.
Further, the width in described feeding portion and height are determined according to the size of the casting thermal center.
Further, the depth of described drainage groove portion is determined according to the order of severity of actual dreg defect.
Further, the intersection of described transition region and drainage groove portion is provided with the curving of castings.
Technique effect of the present utility model is as follows：
1st, the feeding head effectively reduces the middle casting with thick big boss position or large scale square hole position
Be mingled with and rarefaction defect, realize feeding and collection slag function.
2nd, it is not required to set chill just can realize the feeding of local heat energy-saving position, makes cast properties more homogeneous, reduces simultaneously
Moulding workload.
3rd, allowance need not be increased, the difficulty of processing of successive castings is reduced, while the drainage power produced by drainage trough
Make the more thorough of casting field trash exclusion.
4th, because scum riser and casting connection area are smaller, subsequently it is easy to remove.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is application schematic diagram of the utility model in the casting with thick big boss.
Fig. 3 is application schematic diagram of the utility model in the casting with large scale square hole.
Embodiment
There is the feeding head with collection slag effect described in the utility model drainage to lead slag function, local thick big for existing
In the casting of boss or large scale square hole, feeding and collection slag function are realized, effectively reduces and is mingled with and rarefaction defect.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but should not be limited with this
Make protection domain of the present utility model.
Referring to Fig. 1, feeding head of the diagram with collection slag effect is arranged at the die joint F of sandbox, at die joint F
At the upper plane at casting P boss position or at the baseplane at casting P square holes position.
The feeding head includes drainage groove portion 1, feeding portion 2 and transition region 3.
The transition region 3 connects the casting P, and the upper edge of the transition region 3 is concordant with the die joint F.To ensure
Drainage effect, the length b of the transition region 3 should take 2~4 times of itself thickness a of the transition region 3, to ensure the drainage groove portion 1
The intensity of the molding sand of forming part between casting P, the length b of the transition region 3 should be greater than 50mm.
The drainage groove portion 1 is connected with the transition region 3, and the upper edge of the drainage groove portion 1 and the die joint F are flat
Together.The depth e of the drainage groove portion 1 can determine that depth is deeper to be removed according to the order of severity of dreg defect in actual production conditions
Slag effect is better.The intersection of the transition region 3 and drainage groove portion 1 is provided with curving of castings R.
The feeding portion 2 is connected to the top of the drainage groove portion 1, and the width c and the drainage trough in the feeding portion 2
The width in portion 1 is identical.The width c and height d in the feeding portion 2 are determined according to the size of the casting P thermal centers.
The utility model casts plane at casting P boss position or square hole baseplane sets die joint F, during for moulding
Outwards draw and feeding head is set above drainage trough, drainage trough, so can flow into drainage when pouring molten iron reaches drainage groove portion 1
Groove, while the field trash on periphery can together enter drainage trough with molten iron, the size of drainage groove portion 1 is bigger, the effect that field trash is drawn
Better, after the filling of drainage groove portion 1 is full, field trash can enter in the feeding portion 2 of top, will not thus return in casting P.
Feeding head described in the utility model can be used for locally lying in the casting of thick big boss, as shown in Fig. 2 institute
Feeding head A is stated to be connected at the die joint F of casting P boss position P1 upper plane.Feeding head A described in the utility model
It can be used in the casting P with large scale square hole P2, see that Fig. 3, the feeding head A are connected to casting P large scale side
At the die joint F of hole P2 baseplane.
It above are only preferred embodiment of the present utility model, it must further be noted that, those skilled in the art Fan Yiben
Various equivalent modifications, change and amendment that utility model application content is made, should all turn into the protection model of the utility model patent
Enclose.
