Detailed description of the invention
Below in conjunction with accompanying drawing, structure of the present invention and the course of work are described further.
With reference to accompanying drawing 1a, shown in Fig. 1 b and Fig. 1 c, a kind of mould structure, be fixed on the solid plate 1 on lathe steady job table top when comprising work, above solid plate 1, be provided with Angle Pin 2, locking wedge 3, cover half mold insert 4, Angle Pin 2 close-fitting is in the corresponding inclined hole of solid plate 1, locking wedge 3 passes through together with screw fastening with solid plate 1, and cover half mold insert 4 and solid plate 1 are located by concave station, and screw fastening together; Angle Pin is arranged on the outside of locking wedge, and (being as the criterion with the position of mold cavity) strengthens locking strength and stiffness;
Be fixed on lathe when also comprising work to move moving platen 6(moving platen 6 on work top and move work top by other parts (not shown in FIG.) and lathe and be fixed together), driving force comes from the mould opening force of die casting machine or injector; Be provided with pressing plate 16, slide 9, insert 7 and limited block 11 above moving platen 6, insert 7 and moving platen 6 are located by concave station, and screw fastening together.
With reference to shown in Fig. 2, Fig. 3, Fig. 4 and Fig. 5, wherein slide 9 and pressing plate 16 contact one side and have been provided with T-shaped profile 9a with moving platen 6, and have rectangle positioning boss 8a with shaping mold insert 8 mating surface, the position coordinated with Angle Pin 2 offers inclined hole 2a; The inclined-plane 3a that gradient is β is made with locking wedge 3 mating surface; Usually, the gradient α of inclined hole is 0-30 °, and the gradient β on the inclined-plane coordinated with locking wedge is 2-33 °.
And described moving platen 6 forms T-slot 6a with pressing plate 16, pressing plate 16 is located by the groove of moving platen 6, to be tightened together formation T-slot by the 3rd screw 15, slide 9 and shaping mold insert 8 are located by rectangular boss and groove, tightened together by the first screw 10, the T-slot that the T-shaped profile of slide 9 and moving platen 6 and pressing plate 16 are formed is slidably matched, limited block 11 is fastened on a side of moving platen 6 by the second screw 12, the stroke of restriction slide 9, reset screw 14 overlaps spring 13 and is fitted together through limited block 11 and slide 9 spiral shell.
With reference to Fig. 5, shape and the forming part profile of described shaping mold insert match, and shaping mold insert is also provided with the concave station matched with slide.
The course of work of the present invention is such:
Start mould and be in die sinking (dynamic, cover half separates) state, add man-hour, lathe drives dynamic model assembly to move to cover half assembly, matched moulds process (dynamic, cover half is combined).The projection in dynamic model direction of the moulding section of the shaping mold insert of die sinking initial period is also always on forming part.
Slide 9 moves to solid plate 1 with moving platen 6, namely move to Angle Pin 2, Angle Pin 2 inserts in inclined hole that slide 9 adapts with Angle Pin 2, after the inclined-plane of Angle Pin 2 contacts with slide 9 inclined hole, Angle Pin 2 gives slide 9 applied pressure, and the resistance lower slider 9 overcoming spring 13 moves the direction vertical with matched moulds direction, an edge and moves to mold cavity 5 to cover half direction.
Matched moulds when position, locking wedge 3 inclined-plane and slide 9 contact of incline plane, locking wedge 3 inclined-plane extruding slide 9, shift shaping mold insert 8 onto position; Dynamic, cover half is combined in together simultaneously, and matched moulds completes.
Equipment is injected and is started, pressurize, parting, and at parting initial period, lathe drives dynamic model assembly towards moving away from cover half assembly direction (dynamic, cover half separates).Slide 9 moves towards away from solid plate direction with moving platen 6, namely move away from Angle Pin 2 direction, first slide 9 inclined-plane and locking wedge 3 inclined-plane depart from, then outwards pull out in the inclined hole that Angle Pin 2 adapts with Angle Pin 2 from slide 9, after the inclined-plane of Angle Pin 2 contacts with slide 9 inclined hole, Angle Pin 2 gives slide 9 applied pressure, slide 9 is while towards moving the direction vertical with parting direction, an edge away from cover half direction towards moving away from mold cavity direction, in this process, because shaping insert 8 tightens together with slide 9, and slide 9 is in the T-slot that moving platen 6 and pressing plate 16 are formed, it can only slide in T-slot along the direction vertical with parting direction, can not move along with parting direction, it can only move along parting direction with dynamic model, so shaping mold insert can only move with the direction in dynamic model (synchronously) edge and parting direction, while with slide along the direction vertical with parting direction towards moving away from mold cavity direction, the projection of moulding section in dynamic model direction is also always on forming part, that is shaping mold insert 8 is stuck in forming part on moving platen firmly.At this moment dynamic, cover half has separated a segment distance, dynamic model assembly continues motion, slide 9, shaping mold insert 8 under the effect of Angle Pin 2 away from forming part, final and forming part departs from completely, slide 9 puts in place under the acting in conjunction of Angle Pin 2, limited block 11 and spring 13, forming part ejects from insert by the ejecting mechanism that lathe ejecting mechanism promotes mould, and whole mould production process terminates.
Further, formed in mould part, in point mold process, is trapped in the side being provided with ejecting mechanism steadily, reliably, is generally dynamic model.
More than show and describe general principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
