Abstract
The utility model provides a mould structure of loosing core, its simple structure realizes that single drive carries out a plurality of plugs and looses core simultaneously, has reduced mould manufacturing cost, its characterized in that betterly: the automatic forming machine comprises a base, wherein a gear is arranged on the base and is connected with a rotating disk through a gear shaft, a plurality of movable connecting rods are arranged on the rotating disk and are respectively connected with a sliding block, the sliding blocks are connected with mandrils, a driving device is arranged corresponding to the gear and is connected with a rack, and the rack is meshed with the gear.
Description
Technical Field
The utility model relates to a cast technical field of mould, in particular to mould structure of loosing core.
Background
In the die casting, when a plurality of core rods need to be pulled core, the core is respectively pulled core for a single core rod by the existing core pulling structure, the structure makes the die structure more complex, and the independent core pulling is carried out by an air cylinder, so that the production cost of the die is increased.
Disclosure of Invention
To the technical problem, the utility model provides a mould structure of loosing core, its simple structure realizes that single drive carries out a plurality of plugs and looses core simultaneously, has reduced mould manufacturing cost betterly.
The technical scheme is as follows: the utility model provides a mould structure of loosing core which characterized in that: the automatic forming machine comprises a base, wherein a gear is arranged on the base and is connected with a rotating disk through a gear shaft, a plurality of movable connecting rods are arranged on the rotating disk and are respectively connected with a sliding block, the sliding blocks are connected with mandrils, a driving device is arranged corresponding to the gear and is connected with a rack, and the rack is meshed with the gear.
It is further characterized in that: the driving device is an air cylinder; the slider is connected with the guide rail.
The above structure is adopted in the utility model, the gear passes through the gear shaft and connects the rotary disk, be provided with many movable connecting rods on the rotary disk, connecting rod link block, the plug is connected to the slider, it is provided with drive arrangement to correspond the gear, drive arrangement connects the rack, rack and gear engagement, drive arrangement drives the rack and removes, the rack drives gear revolve, the gear drives the rotary disk and rotates, thereby make movable connecting rod on the rotary disk rotate, produce relative displacement, it is ejecting with the plug with the slider, loose core has been realized, because single drive is gone on a plurality of plugs and is loosed core simultaneously, mould manufacturing cost has been reduced betterly.
Drawings
FIG. 1 is a schematic front view of the core-pulling structure of the mold of the present invention;
fig. 2 is a top view of fig. 1.
Detailed Description
The present invention will be further explained with reference to the drawings and examples.
As shown in fig. 1 and 2, the mold core pulling structure comprises a base 1, a gear 2 is arranged on the base 1, the gear 2 is connected with a rotating disk 4 through a gear shaft 3, a plurality of movable connecting rods 5 are arranged on the rotating disk 4, the connecting rods 5 are respectively connected with a slide block 6, the slide block 6 is connected with a core rod 7, the slide block 6 is connected with a guide rail 10, a driving device 8 is arranged corresponding to the gear 2, the driving device 8 is connected with a rack 9, the rack 9 is meshed with the gear 2, the driving device is a cylinder, the cylinder drives the rack to move, the rack drives the gear to rotate, the gear drives the rotating disc to rotate, thereby leading the movable connecting rod on the rotating disk to rotate and generate relative displacement, leading the slide block to move through the guide rail which is fixed on the die body and pushes the slide block communicated with the core rod out, realizing core pulling, because single drive carries out a plurality of plug and looses the core simultaneously, has reduced mould manufacturing cost betterly.
The cylinder that drive arrangement adopted in this embodiment, of course also can adopt other drive arrangement such as connecting rod promotion, as long as can realize rack motion, rack drive gear motion, the gear drives the rotary disk and rotates, and the rotary disk rotates and drives the connecting rod and promote the motion of slider intercommunication plug, realizes loosing core, all is the utility model discloses a protection scope.
The present invention and the embodiments thereof have been described above schematically, and the description is not limited thereto, and the embodiment shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto, and those skilled in the art will be suggested by the teachings thereof, and without departing from the spirit of the present invention, without creatively designing the structural mode and the embodiments similar to the technical solution, all of which shall fall within the protection scope of the present invention.
