/ 2nd of 5 width, to ensure that two chucking powers that the correspondence working face of suspension rod 1 is bestowed to core 20 act on same straight line
On.
The circular curve shape of the suspension rod clamping part 10 is molded using the intelligent design of PROE softwares, circular curve
Optimization design, ensure that the suspender reduces the unnecessary collision produced between sand mold 20 in use, simultaneously
Ensure to clamp core 20 under chucking power as small as possible and sling.The circular curve shape, close to the curvature of end regions
Radius is more than the radius of curvature close to the region of the first linkwork 40.
In order to optimize structure, the linkwork 50 of the first linkwork 40 and second is both designed as cirque structure.Root
According to the difference of suspender application product, the width of the hanger rod for hanging appliance clamping part working face 5, which can be done, the adaptability such as widens or reduces
Adjustment, and the width of the suspension rod clamping part working face 5 on same frame suspender can also be incomplete same, to adapt to clamped sand
Core 20 or the specific feature of other workpiece and requirement.Meanwhile, the length of the rotating shaft 2 and hanging axis 3 also can be according to clamped sand
The concrete condition of core 20 or other workpiece does accommodation.
The beneficial effects of the utility model are：There is provided one kind be applied to the migration of Foundry Production middle-size and small-size casting sand core and under
The suspender of core, both can be with hand-held, can also be by mechanical suspender belt auxiliary operation, the perfect lower core hand of small-sized casting sand core
Section, so as to reduce labor strength, improves production efficiency, particularly can also effectively mitigate the lower core process of core migration
In the core that causes scrap or core damage, reduce the waste to raw material, improve the quality of cast article.
