Accompanying drawing explanation
Fig. 1 is that this core conformal supporting plate floats mold closing mechanism front view.
Fig. 2 is that this core conformal supporting plate floats mold closing mechanism left view.
Fig. 3 is that this core conformal supporting plate floats the active sphere assembled view of mold closing mechanism.
Detailed description of the invention
By reference to the accompanying drawings the detailed description of the invention of invention is described.
As Fig. 1, this core conformal supporting plate mold closing mechanism that floats comprises roller-way 1, and on this, roller-way 1 has rectangle roller bed frame be made up of horizontal, longeron, this roller bed frame below by rolling bearing units assembling roll body, described roll body is layout longitudinally, transversely arranged in a row.The both sides, front and back of roller-way 1 are respectively equipped with core conformal supporting plate retaining mechanism 2 on described, this core conformal supporting plate retaining mechanism 2 has horizontal locking cylinder on described on roller-way 1, rear end and the locking cylinder back seat be fixed on described upper roller-way 1 of this locking cylinder are hinged, the front end of this locking cylinder and a upper end of locking claw are hinged, middle part and the locking claw bearing be fixed on described upper roller-way 1 of this locking claw are hinged, the upper plate lower plane that the lower end of locking claw can be held in core conformal supporting plate realizes fixing of core conformal supporting plate and upper roller-way 1.The both sides, front and back of roller-way 1 are symmetrical on described respectively arranges a pair for described core conformal supporting plate retaining mechanism 2.The both sides, front and back of roller-way 1 are respectively equipped with core conformal supporting plate relocation mechanism 3 on described, and the both sides, front and back of roller-way 1 are symmetrical on described respectively arranges a pair for this core conformal supporting plate relocation mechanism 3.
As Fig. 2, described core conformal supporting plate relocation mechanism 3 has horizontal driving oil cylinder 4, rear end and the driving oil cylinder back seat 5 be fixed on above described upper roller-way 1 of this driving oil cylinder 4 are hinged, the upper end of the front end of this driving oil cylinder 4 and a L-shaped floating claw 6 is hinged, middle part and the claw bearing 7 be fixed on described upper roller-way 1 of this floating claw 6 are hinged, on the lower end of described floating claw 6, be provided with active sphere 8, this active sphere 8 contacts with the upper plate lower plane of core conformal supporting plate 9 and coordinates.
As Fig. 3, blind hole is provided with on the lower end of described floating claw 6, assembling blind hole liner 10 in this blind hole, spherical groove is provided with on blind hole liner 10, ball 11 arranges one deck at described spherical groove inner surface, and described active sphere 8 is arranged in the active sphere assembly cavity that is made up of ball 11.In described blind hole, be provided with blind hole liner fix snap ring 12, in described spherical groove, be provided with ball and active sphere limited location snap ring 13.Blind hole liner fixes the open-type Spring Card that snap ring 12 and active sphere limited location snap ring 13 are square-section.Blind hole liner is fixed snap ring 12 and is assemblied in the snap ring fitting groove on described blind hole top, is fixed in blind hole by blind hole liner 10.Active sphere limited location snap ring 13 is assemblied in the snap ring fitting groove on described spherical groove top, ball 11 and active sphere 8 is limited in spherical groove.Central through hole 14 is provided with, for facilitating the dismounting of blind hole liner 10 at the bottom of the hole of described blind hole.
This core conformal supporting plate mold closing mechanism that floats is assemblied on drawn on rollover machine, drives its clamping completing core conformal supporting plate, upset, the work such as matched moulds, the demoulding of floating by drawn on rollover machine.Its specific works process is: when this core conformal supporting plate float mold closing mechanism be in drawn on rollover machine bottom time, core conformal supporting plate is transported on the upper roller-way of this device, the locking cylinder action of core conformal supporting plate retaining mechanism, locking core conformal supporting plate, then float mold closing mechanism and core conformal supporting plate of this core conformal supporting plate rotates 180 under the drive of turn drive motor, now float mold closing mechanism and core conformal supporting plate of this core conformal supporting plate is placed in drawn on rollover machine top, the driving cylinder rod of core conformal supporting plate relocation mechanism stretches out, four floating claws perform the preparation of placing core conformal supporting plate.Locking claw is opened in the locking cylinder action of core conformal supporting plate retaining mechanism, and core conformal supporting plate drops on the active sphere of four floating claws under gravity.Then core box enters the lower roller of drawn on rollover machine and is locked by core box supporting plate retaining mechanism.Upper and lower roller-way under the driving of hoist cylinder to drawn on rollover machine central motion; when core conformal supporting plate when above contacts with core box below; because core conformal supporting plate is seated on active sphere; core conformal supporting plate is moved horizontally; namely quick condition is in, until core conformal supporting plate and core box get togather completely.Now the driving oil cylinder of core conformal supporting plate relocation mechanism opens floating claw; the locking claw locking core conformal supporting plate of core conformal supporting plate retaining mechanism; roller-way oscilaltion cylinder action holds core conformal supporting plate and core box tightly, and the drawn on rollover machine mold closing mechanism that again floated by core conformal supporting plate rotates 180 °.The vibrating motor of vibration mould emptier starts to vibrate the demoulding, until completing till core box and mould and core depart from.Drawn on rollover machine roller-way oscilaltion oil cylinder is opened, and core drops on core conformal supporting plate, is separated with core box and mould, completes demoulding work.Drawn on rollover machine roller-way reducing motor operates, and core conformal supporting plate and core is sent, completes the whole course of work of the core demoulding.
