The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 2 is a metal insert injection mold structure schematic diagram of the present utility model; Fig. 3 is a metal insert injection mold structure side view of the present utility model.
See also Fig. 2 and Fig. 3, metal insert injection mold of the present utility model, comprise cover half die cavity 2 that is positioned at solid plate 3 and the dynamic model die cavity 4 that is positioned at moving platen 5, injecting products 6 is formed in the cover half die cavity 2, be provided with retaining pin 7 in the described dynamic model die cavity 4, retaining pin 7 passes dynamic model die cavity 4 and dynamic model impression bolster 5, be fixed on the jacking block 8, wherein, jacking block 8 has slide block 9, jacking block 8 links to each other with the dovetail groove of slide block 9 by the band inclined plane, the drive jacking block 8 that is displaced sideways of slide block 9 moves up and down, slide block 9 links to each other with cylinder piston rod by contiguous block 13, and cylinder 12 is driven by logical the ending of digital time relay 14 control magnetic valves 15, and the timing node that digital time relay 14 postpones output is located at material and fills full die cavity, the period that the inserts product is inner also uncured.
Fig. 4 is metal insert of the present utility model and retaining pin structural representation; Fig. 5 is the oat tail groove structure schematic diagram of jacking block of the present utility model and slide block.
Please continue referring to Fig. 4 and Fig. 5, metal insert injection mold of the present utility model, cover half die cavity 2 is fixed on the solid plate 3, dynamic model die cavity 4 is fixed on the moving platen 5, be provided with retaining pin 7 in the dynamic model die cavity 4, retaining pin 7 passes dynamic model die cavity 4 and dynamic model impression bolster 5, be fixed on the jacking block 8, jacking block 8 has slide block 9, jacking block 8 and slide block 9 link to each other by dovetail groove, and the angle of inclination has been done by dovetail groove mechanism, and being displaced sideways of slide block 9 can drive jacking block 8 and move up and down, slide block 9 has supporting plate 10, and supporting plate 10 is fixed on moving platen 5 bottom surfaces by bolt 11.Slide block 9 links to each other with cylinder piston rod by contiguous block 13, and cylinder 12 is driven by logical the ending of digital time relay 14 control magnetic valves 15.When deciding die joint and cast gate, to confirm the direction of metal insert 1 distortion earlier, add inserts backstay 7 in a side of being out of shape.
The metal insert injection mold course of work of the present utility model is as follows: behind the mould matched moulds, injection machine plays the high pressure start injection, and when playing high pressure, machine flows to digital time relay 14 with the 24V low tension, opens digital time relay 14.The timing node that digital time relay 14 postpones output is located at material and fills full die cavity, inner also uncured period of inserts product substantially, and this time period can be penetrated by injection test and be obtained.After digital time relay 14 is deferred to, connect magnetic valve 15 and drive cylinder 12, cylinder 12 pulling slide blocks 9, slide block 9 drives jacking block 8 and moves down, retaining pin 7 moves down thereupon and breaks away from inserts 1, and under the pressurize of injection machine, material continues to fill die cavity, 7 places are filled up with former retaining pin, envelope inserts.
