Embodiment
Fig. 1-9 show related description figure of the present invention；A kind of more cave unit acupuncture point four sides core pullings of preceding mould become pouring type note Mould, including curved pin 1, upper core mold insert 2, oblique core-pulling slide block 3, wearing plate 4, de- material mold insert 5, lower core mold insert 6, pressing plate 7, The box-like cavity slide block 11 of spot pouring mouth runner 8, side gate sprue 9, spring spiro rod 10, valve, the box-like cavity slide block spring 12 of valve, top Plate is coupled post 13, lower link bar spring 14, lower link bar 15, stripper plate stop screw 16, guide pillar 17, long draw spring 18, long draw 19th, upper clamping plate 20, stripper plate 21, impression bolster 22, ejection push pedal 23, lower core fixing plate 24, die shoe plate 25.
Mould die carrier structure component composition include guide pillar 17, upper clamping plate 20, stripper plate 21, impression bolster 22, Eject push pedal 23, lower core fixing plate 24, die shoe plate 25.
The mould mold layout is the cave of a mould eight, and two die cavitys form a unit.
The die casting system includes spot pouring mouth runner 8, side gate sprue 9 and its secondary runner and cast gate, side and poured Mouth sprue 9 and its secondary runner and cast gate are put together by the runner on the box-like cavity slide block 11 of two valves, in whole mould There is the box-like cavity slide block of same valve 11 8；Spot pouring mouth runner 8 is opened on impression bolster 22.
The cave of mould two is a unit, and a unit includes two box-like cavity slide blocks 11, two of curved 1, two valve of pin The lower core mold insert 6 of the individual oblique de- material mold insert 5, two of core-pulling slide block 3, two of upper core mold insert 2, two.
The mould single cave molding assembly is tiltedly taken out including the box-like cavity slide block 11, one of 2, two valves of a upper core mold insert The lower core mold insert 6 of the de- material mold insert 5, one of core sliding block 3, one.
The mold ejection mechanism component includes eight de- material mold inserts, 5, two top plates and is coupled 23 groups post 13, ejection of push pedal Into；De- material mold insert 5 is installed in ejection push pedal 23 by screw, and top plate is coupled post 13 and joined by screw thread and the ejection fastening of push pedal 23 Knot.
Described one die cavity unit die cavity of mould is closed by the box-like valve of cavity slide block 11 of two valves and formed, the box-like cavity slide block of valve 11 be the box-like sliding block of cover half valve, is installed on by T-slot on impression bolster 22, and it slides core pulling power is slided by the box-like die cavity of valve Block spring 12 is provided, and the box-like cavity slide block spring 12 of valve is placed on spring spiro rod 10；Core is slided by upper core mold insert 2, oblique core pulling The head of block 3, de- material mold insert 5, lower core mold insert 6 are formed；Upper core mold insert 2 is installed on impression bolster 22, lower core mold insert 6 It is installed on lower core fixing plate 24.
The mould single mode cave side core-pulling mechanism composition includes curved pin 1, oblique core-pulling slide block 3, wearing plate 4.
The mould in three times open by parting, and first, second time parting opens the core pulling for completing oblique core-pulling slide block 3 and hole irrigation The separation of mouth runner 8 and side gate sprue 9；Third time parting complete the box-like cavity slide block 11 of valve, upper core mold insert 2 and it is de- From；Mould parting spacing controlling organization is by forming including lower link bar spring 14, lower link bar 15, stripper plate stop screw 16, long drawing Bar spring 18, long draw 19 form.
During real work, as shown in Figure 8, Figure 9, its operation principle is as follows：
1）After first time parting mould is opened, Injection Motor Template pulls mould dynamic model part to retreat, as shown in figure 8, mould Tool is opened first at the first die joint PL1, and oblique core-pulling slide block 3 completes side core-pulling action under the stirring of curved pin 1；Meanwhile point Sprue channel 8 breaks separation with side gate sprue 9 at spot pouring mouth；
2）Second of parting mould dynamic model part continues to retreat, and mould is opened at the second die joint PL2, spot pouring mouth stream Road 8 is extracted by stripper plate 21 from die gate casing, Automatic-falling；
3）Third time parting mould dynamic model part continues to retreat, as shown in figure 9, mould is beaten at three parting line PL3 Open, now, the box-like cavity slide block 11 of valve slides downwards under the promotion of the box-like cavity slide block spring 12 of valve along T-slot thereon, So as to complete the side core pulling action of the box-like cavity slide block 11 of valve, synchronously, upper core mold insert 2 also departs from from product, so as to Product is stayed on lower core mold insert 6；
4）Product ejection die dynamic model part continues after backing to certain distance, and injection machine push rod withstands top plate and is coupled post 13, top plate, which is coupled post 13, will withstand ejection push pedal 23, so as to which ejection push pedal 23 will withstand de- material mold insert 5 by product from upper core The demoulding is released on mold insert 2；
5）Reset mold parting surface to close by PL3-PL2-PL1 successively, the box-like cavity slide block 11 of valve first resets, and is then Oblique core-pulling slide block 3 resets, and after mould closure completely, waits next injection cycle to start.
Specific embodiment described herein is only the technology neck belonging to the present invention to spirit explanation for example of the invention The technical staff in domain can be made various modifications or supplement to described specific embodiment or be replaced using similar mode Generation, but without departing from the spiritual of the present invention or surmount scope defined in appended claims.
