Detailed description of the invention
In order to make technical scheme of the present invention more clearly show, below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figures 1 to 5, be the core nose fixture 100 of a preferred embodiment of the present invention, for foundry goods core nose being located and is fixed in core in the process of casting sand core.This core nose fixture 100 entirety is in round table-like setting, comprise lower surface 60 and the upper surface 70 of a circle, the top of this core nose fixture 100 is provided with a groove 80, and this groove 80 is communicated with the middle part of described upper surface 70 and the opposite flank of this core nose fixture 100 is laterally run through in left and right.Be provided with about one screwed hole vertically run through 90 in this core nose fixture 100, this screwed hole 90 runs through the bottom land of described lower surface 60 and described groove 80.
The diameter of described lower surface 60 is greater than the diameter of upper surface 70.In the present embodiment, the diameter of this lower surface 60 is 50 ~ 100mm, and the diameter of upper surface 70 is 45 ~ 90mm.This lower surface 60 is provided with some locating holes 10, each locating hole 10 is provided with the first magnet 15.Particularly, described locating hole 10 is blind round hole, is evenly distributed on described screwed hole 90 around, and in circular arrangement.Described first magnet 15 is fixed in locating hole 10 by glue, and the bottom surface of the first magnet 15 and described lower surface 60 are consistent, and namely ensures that the lower surface 60 of core nose fixture 100 installs the flatness after described first magnet 15 or flatness.
The degree of depth of described groove 80 is 20 ~ 50mm.The cross section of this groove 80 is trapezoidal setting wide at the top and narrow at the bottom, and namely the cross section of this groove 80 is greater than the length on the base near lower surface 60 near the length of the top margin of upper surface 70, to ensure that core nose fixture 100 is taken out smoothly from core.The bottom width of this trapezoidal cross section is 10 ~ 30mm, upper wide be 5 ~ 20mm, and it is wide to remain that bottom width is less than, and namely groove 80 becomes large towards upper surface 70 gradually from the middle part of core nose fixture 100.The bottom land of this groove 80 is provided with some installing holes 20, each installing hole 20 is provided with the second magnet 25.Particularly, described installing hole 20 quantity is two, is symmetricly set on the both sides of described screwed hole 90.Described second magnet 25 is fixed in installing hole 20 by glue, and the end face of the second magnet 25 and the bottom land of described groove 80 are consistent, to ensure that the bottom land of groove 80 installs the later flatness of the second magnet 25.
Understandably, the size of described core nose fixture 100 and groove 80 size thereof, all specifically determine according to the size of foundry goods core nose and the intensity of core nose fixture 100.Described core nose fixture 100 can be made up of the material such as stainless steel, copper alloy.
When casting sand core, core nose fixture 100 of the present invention is placed on the position that core mold (i.e. core box) correspondence arranges foundry goods core nose, by the magnetic force of the first magnet 15 by the fixation of core nose fixture 100; Then be placed in the groove 80 of core nose fixture 100 by ready foundry goods core nose, spacing by groove 80 pairs of foundry goods core noses, the second magnet 25 pairs of foundry goods core noses are spacing simultaneously attracts to fix by magnetic force; After installing core nose fixture 100 and foundry goods core nose, in core box, carry out core production, the core wherein completed is connected with foundry goods core nose; Finally, core, foundry goods core nose and core nose fixture 100 are taken out in the lump from core box, by screwing in the screwed hole 90 of core nose fixture 100 with the externally threaded bottle opener of correspondence, thus the bottom surface of core nose fixture 100 from core is taken out, complete whole core manufacture process.
Core nose fixture 100 of the present invention, when the Design of Dies of core makes without the need to considering that core nose is located, reduces the manufacture difficulty of mould; And when producing, can be fixed fast the position of foundry goods core nose in core box, improve production efficiency, decrease core percent defective.
The above embodiment only have expressed one embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
