Embodiment
In order that technical scheme can more clearly show, further is made to the present invention below in conjunction with the accompanying drawings
Explanation.
As shown in Figures 1 to 5, it is the core nose fixing device 100 of a preferred embodiment of the present invention, in casting sand core
During casting core nose is located and fixed within core.The core nose fixing device 100 is overall to be set in round table-like, including a circle
The lower surface 60 of shape and upper surface 70, the top of the core nose fixing device 100 are provided with a groove 80, and the groove 80 is connected on described
The middle part and left and right on surface 70 extend transversely through the opposite flank of the core nose fixing device 100.In the core nose fixing device 100
Provided with about one screwed hole 90 run through vertically, the screwed hole 90 is through the lower surface 60 and the bottom land of the groove 80.
The diameter with diameter greater than upper surface 70 of the lower surface 60.In the present embodiment, the lower surface 60 is a diameter of
50 ~ 100mm, a diameter of 45 ~ 90mm of upper surface 70.The lower surface 60, which is provided with some positioning holes 10, each positioning hole 10, pacifies
Equipped with the first magnet 15.Specifically, the positioning hole 10 is blind round hole, is evenly distributed on around the screwed hole 90, and
In circular arrangement.First magnet 15 is fixed in positioning hole 10 by glue, and the bottom surface of the first magnet 15 with it is described
Lower surface 60 is consistent, that is, ensures that the lower surface 60 of core nose fixing device 100 installs the flatness after first magnet 15
Or flatness.
The depth of the groove 80 is 20 ~ 50mm.The cross section of the groove 80 is in trapezoidal setting wide at the top and narrow at the bottom, i.e., this is recessed
The cross section of groove 80 is more than the length close to the base of lower surface 60 close to the length of the top margin of upper surface 70, to ensure that core nose is consolidated
Determine device 100 smoothly to take out from core.The bottom width of the trapezoidal cross section is 10 ~ 30mm, upper a width of 5 ~ 20mm, and is protected all the time
Hold bottom width and be increasingly towards upper surface 70 from the middle part of core nose fixing device 100 less than upper width, i.e. groove 80 and become big.The groove 80
Bottom land is provided with some mounting holes 20, each mounting hole 20 and is provided with the second magnet 25.Specifically, the quantity of mounting hole 20 is
Two, it is symmetricly set on the both sides of the screwed hole 90.Second magnet 25 is fixed in mounting hole 20 by glue, and second
The bottom land of the top surface of magnet 25 and the groove 80 is consistent, to ensure that it is later that the bottom land of groove 80 installs the second magnet 25
Flatness.
It is to be appreciated that the size and its size of groove 80 of the core nose fixing device 100, all in accordance with casting
The size of core nose and the intensity of core nose fixing device 100 are specifically determined.The core nose fixing device 100 can be by stainless
The materials such as steel, copper alloy are made.
When casting sand core, the core nose fixing device 100 of the present invention is placed on core mold（That is core box）It is correspondingly arranged
The position of casting core nose, by the magnetic force of the first magnet 15 by the fixation of core nose fixing device 100；Then by ready casting
Part core nose is placed in the groove 80 of core nose fixing device 100, spacing to casting core nose by groove 80, while the second magnet 25
It is spacing to casting core nose to attract to fix by magnetic force；Install after core nose fixing device 100 and casting core nose, enter in core box
Row core is produced, wherein the core completed is connected with casting core nose；Finally, core, casting core nose and core nose are fixed and filled
100 are put to take out from core box in the lump, by screwing in the screwed hole 90 of core nose fixing device 100 with the externally threaded bottle opener of correspondence,
So as to which core nose fixing device 100 be taken out from the bottom surface of core, whole core manufacturing process is completed.
The core nose fixing device 100 of the present invention, need not consider that core nose is positioned when the mold design of core makes, reduce
The manufacture difficulty of mould；And in production, position of the casting core nose in core box can be rapidly performed by fix, life is improved
Efficiency is produced, core percent defective is reduced.
Embodiment described above only expresses one embodiment of the present invention, and it describes more specific and detailed, but simultaneously
Therefore the limitation to the scope of the claims of the present invention can not be interpreted as.It should be pointed out that for one of ordinary skill in the art
For, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the guarantor of the present invention
Protect scope.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
