Abstract
The utility model provides a pressure casting mould for making bearing inner spacer, which is used for producing a double-row radial bearing. The utility model is characterized in that 18 or 19 rolling type oblique slide bar core pulling mechanisms are uniformly arranged on the circumference of the moving pattern plate of the pressure casting mould, provided the pressure casting mould for making bearing inner spacer is adopted by a pressure casting machine, no cutting formed in one piece process can be adopted to produce the bearing inner spacer, the original material using ratio can be raised from 15% to 99% by the pressure casting mould for making bearing inner spacer, and large quantity precious metal can be saved.
Description
The utility model belongs to a kind of mould, particularly produces the die casting that a kind of retainer is used.
The retainer of double row self aligning spherical roller bearing, domestic each Bearing Factory all adopts entity casting cover or strand at present, and again through multiple tracks machined prefaces such as car, borings, manufacturing forms.Its stock utilization is 15% only, has wasted a large amount of precious metals, needs multiple cutting machines simultaneously, takies a large amount of machining periods, consumes energy, and cost is higher, and economic benefit is bad.
Adopt and do not have the cutting one-step moulding method, produce retainer, can increase economic efficiency significantly, the key equipment that adopts this method is a die casting, because 18 or 19 the pocket holes (the dress roller is used) with 9-10 ° of angle of horizontal plane folder that evenly distribute on the retainer of double row self aligning spherical roller bearing cast out this type of hole in mould, difficulty is very big, therefore, some study this purpose unit, and are all stranded herein.
The purpose of this utility model provides a kind of die casting that double row self aligning spherical roller bearing is used of producing, and produces retainer with this mould, can avoid above-mentioned deficiency effectively.
The purpose of this utility model is achieved in that it is by solid plate, moving platen, compositions such as dynamic model support plate and Bottom clamp plate, 18 or 19 holes that become 9-10 ° of inclination angle with the plane because biserial entad evenly distributes on the retainer of spherical bearing, therefore, on the moving platen circumference of die casting, uniform 18 or 19 oblique slide bar core-pulling mechanisms of roller, concrete composition is: be distributed with 18 or 19 oblique slide openings that become 80-81 ° of angle with die joint on the moving platen, in oblique slide bar is housed, the front end of each oblique slide bar is a core, roll identical, the promptly complete cylindrical structural in hole in its shape and the bearing.The middle part can produce relative slip for cylindrical slide mass with above-mentioned oblique slide opening.The rear portion is shoulder shape, and afterbody is equipped with rotatable pin.
The structure dynamic declaration:
The matched moulds state: tiltedly the non-moulding position of slide bar front end core is stuck on the template, and tiltedly the raised step of slide bar middle part cylinder and shoulder cylinder intersection, rear portion is stuck in the dynamic model support plate, and oblique slide bar is located vertically, guarantees the required precision of foundry goods pocket hole bottom thickness.
Die sinking pusher state: charging ram promotes moving platen and moves horizontally to the right, the oblique slide opening of 18 or 19 oblique slide bars on moving platen, under the entad component effect that produces to lower slider, the roller bolt that is oblique slide bar afterbody rolls downwards along the moving platen left surface, the level of moving platen move right and tiltedly slide bar inwardly slide, two motions synthetic finished withdrawing retainer 18 or 19 the oblique 9-10 of summary °, the action of pocket pass core guarantees that compression mod casts out qualified retainer fully.
Use the utility model, adopt and do not have cutting one-step moulding method production retainer, it is feather that the utilization rate that can make material rises to 99%(1% by original 15%), saved a large amount of precious metals, cutting machines and machining period have also been saved simultaneously, reduce energy resource consumption, increase economic efficiency significantly.
Further specify the utility model below in conjunction with accompanying drawing.
Fig. 1 is the structural representation (complete section) of the utility model when matched moulds.
Fig. 2 is the partial structurtes schematic diagram of the utility model when die sinking.
Fig. 3 is the vertical view of Fig. 2.
Fig. 4 is the oblique slide bar motion analysis figure of loosing core.
It is made up of solid plate 6, moving platen 3, dynamic model support plate 5 and Bottom clamp plate 4 etc., 18 holes that become 9.5 ° of inclinations angle with the plane because biserial entad evenly distributes on the retainer of spherical bearing, therefore, on the moving platen circumference of die casting, uniform 18 oblique slide bar core-pulling mechanisms of roller; Be distributed with 18 oblique slide openings 7 that become 80.5 ° of angles with die joint on the moving platen, in oblique slide bar 2 is housed, the front end of each oblique slide bar is a core, rolls identical, the promptly complete cylindrical structural in hole in its shape and the bearing.The middle part can produce relative slip for cylindrical slide mass with above-mentioned oblique slide opening.The rear portion is shoulder shape 9, and afterbody is equipped with rotatable pin 1.
The structure dynamic declaration:
The matched moulds state: tiltedly the non-moulding position of slide bar front end core is stuck on the template, and the raised step of oblique slide bar middle part cylinder and shoulder cylinder 9 intersections, rear portion is stuck in the dynamic model support plate locatees oblique slide bar vertically, guarantees the required precision of foundry goods pocket hole bottom thickness.
Die sinking pusher state: charging ram 8 promotes moving platen and moves horizontally to the right, the oblique slide opening of 18 oblique slide bars on moving platen, under the entad component effect that produces to lower slider, the roller bolt that is oblique slide bar afterbody rolls downwards along the moving platen left surface, the level of moving platen moves right and oblique slide bar inwardly slides (referring to Fig. 4), and withdrawing retainer 18 or 19 summaries oblique (9-10 °) are finished in synthesizing of two motions, the action of pocket pass core guarantees that compression mod casts out qualified retainer fully.
Claims (3)
1, a kind of die casting, it is by solid plate, moving platen, compositions such as dynamic model support plate and Bottom clamp plate, it is characterized in that: on around the moving platen of die casting, uniform 18 or 19 oblique slide bar core-pulling mechanisms of roller, be distributed with 18 or 19 oblique slide openings that become 80.5 ° of angles with die joint on the moving platen, in oblique slide bar is housed, the front end of each oblique slide bar is a core, in its shape and the bearing to roll the hole identical, it is complete cylindrical structural, the middle part can produce relative slip for cylindrical slide mass with above-mentioned oblique slide opening, and the rear portion is for takeing on shape, and afterbody is equipped with rotatable pin.
