Abstract

A die-casting die for motor casings comprises a moving die set (1), a fixed die set (2), a forming part, and a core pulling mechanism, and is characterized in that the forming part is mounted on the moving die set (1) and the fixed die set (2). A die guide mechanism is arranged on the moving die set (1) and the fixed die set (2). Five side cores are mounted on five side sliders respectively. Each side slider matches with a corresponding T-shaped guide slide (10) on a moving die (3) and capable of sliding in the slide. The core pulling mechanism pulls out the cores through an angle guide pin. A wedge (13) assists in locking or loosening the core pulling mechanism. Finished products made by the die-casting die are high in size precision, stable in quality, excellent in appearance quality and high in process yield. In addition, the die-casting die is low in cost and convenient to mechanically operate and automatically control.

The specific embodiment
Known that by Fig. 1 the motor casing die casting comprises dynamic model frame 1, cover half frame 2, shaped portion, core-pulling mechanism; Described shaped portion is formed, is the die cavity 5 of motor housing mould by dynamic model 3, cover half 4 and five side core I 17-1, II 18-1, III 19-1, IV 20-1, V 21-1; Core-pulling mechanism is formed shaped portion jointly and is installed on dynamic model frame 1 and the cover half frame 2 by guide runner 10, T shape guide rail 11, wedge block 12, big Angle Pin 13, little Angle Pin 14, five side slide I 17, II 18, III 19, IV 20, V 21, on dynamic model frame 1 and the cover half frame 2 the mould guiding mechanism is arranged, five side cores are installed in respectively on five side slides, each side slide all with dynamic model 3 on the corresponding T shape guide runner of offering 10 match, and can in groove, slide, core-pulling mechanism is finished by Angle Pin and is loosed core, and 12 pairs of core-pulling mechanisms of wedge block are assisted locking or unclamped.
Being known by Fig. 2, is the cover half structure chart.Be provided with 4 wedge blocks 12 that play auxiliary locking effect around cross gate 6, runner 7, the Inner cast gate 8 that indent is arranged on the cover half 4, the big Angle Pin on the described cover half.Because mould is bigger, wedge block 12 makes mold-locked power bigger, and stability is better, prevents secondary heated die dilatancy.Side slide V 21 is finished by the T type guide rail 11 on two on the cover half 4 little Angle Pins 14 and the dynamic model frame 1 and is loosed core.Because this side slide is positioned at baroque cast gate place, so realize loosing core and locking with two little Angle Pins.Be provided with 4 wedge blocks that play auxiliary locking effect around the big Angle Pin.Be provided with 4 wedge blocks that play auxiliary locking effect around the big Angle Pin on the described cover half.
Being known by Fig. 3, is the explosive view of dynamic model and slide block.Overflow launder 9 is arranged on the dynamic model 3.Overflow launder can hold dirty molten metal, and the gas in the die cavity can be discharged by air discharge duct, has reduced defectives such as foundry goods shrinkage cavity, cold shut, misrun, has improved the internal soundness of foundry goods.Offer guide runner 10 on the dynamic model, each side slide and guide runner adopt matched in clearance.Five side slide I 17, II 18, III 19, IV 20, V 21 are loosed core along the direction of guide runner 10 separately respectively by big Angle Pin 13, side slide I 17, side slide II 18, side slide III 19 and side slide IV20 are respectively by wedge block 12 auxiliary lockings, and side slide V 21 is by two on the cover half little Angle Pin 14 lockings.Between five side slides and the active and inactive mold, be provided with the gap between push rod and the dynamic model.Also be provided with ejecting mechanism on the dynamic model 4.After the die sinking, motor casing can be stayed dynamic model, adopts push rod that it is released dynamic model.
The inside die cavity of described cover half, dynamic model, 5 side core compositions is casting structure.Mould is finished under the effect of Angle Pin and is loosed core, and 5 side slides are locked under the effect of wedge block during mould.Be provided with overflow launder 9 on the die joint of mould, the contact-making surface at each side core is provided with overflow launder 9 simultaneously.
Working process of mould: during the mould matched moulds, under the guiding and positioning action of cover half guide pillar and cover half guide pin bushing, the matched moulds system drives dynamic model 3 and moves to cover half 4 directions, simultaneously side slide I 17, side slide II 18, side slide III 19, side slide IV 20 and side core V 20-1 under the Angle Pin effect along the direction matched moulds of guide runner, arrive the operating position, make the mould closure, and tightened by four wedge blocks that are distributed in around the Angle Pin on the cover half frame, make system that enough bigger moulds of clamp force locking are provided.Begin die casting then, by die casting machine work hand aluminium liquid is poured into pressing exerts pressure in the chamber and through injection mechanism enters mold cavity 5 by cross gate 6, ingate 7 respectively, after pressurize a period of time, the matched moulds system drives dynamic model 3 to moving away from cover half 4 directions, 5 side cores separate under the Angle Pin effect simultaneously, separate fully with foundry goods up to 5 side cores, finish the action of loosing core, foundry goods moves after wrapping in and continuing on the dynamic mould core, up to push rod foundry goods is released from mould.During matched moulds, push rod resets, and big Angle Pin 13 makes side slide I 17, side slide II 18, side slide III 19 and side slide IV 20 inwardly reset along guide runner, and two little Angle Pins 14 make side slide V 21 reset along T shape guide rail 11 simultaneously, and mould is prepared die casting next time.
