The specific embodiment

For describing technology contents of the present utility model, structural feature in detail, illustrated in detail below in conjunction with embodiment and conjunction with figs..

See also Fig. 3, eject the structural representation of forced demoulding mechanism for the novel secondary of the utility model.But this mould comprises the master mold side and the male model side of folding, and this master mold side is provided with caster 101 and mother module core 121, and this male model side is overlapped successively by male model benevolence 107, male model plate 102, upper and lower liftout plate 103,104, bottom plate 106 and forms.Eject board 105 and be located at the below of this time liftout plate 104, its end face have eject on hole 108 (seeing also Fig. 4) and this bottom plate 106 to eject hole 109 corresponding, this ejects between board 105 and this upper and lower liftout plate 103,104 and is connected with shutter 122.Limited post 110, push rod 111 1 ends run through this upper and lower liftout plate 103,104, and be fixed in this with screw 112,113 respectively and eject board 105 end faces, these limited post 110 other ends protrude from this upper ejector plate 103 end faces, these push rod 111 other ends run through this male model plate 102, and be connected with the jacking block 114 in being arranged in male model benevolence 107, these push rod 111 ends have thread 115, and it is bitten and closes in this jacking block 114, connect this jacking block 114 and are one.Sleeve 116 bottoms are fixedly arranged on this upper ejector plate 103 with screw 117, and this male model plate 102 and this male model benevolence 107 is run through in the end.Core_pulling pole 118 1 ends are arranged in this sleeve 116, and the other end is sticked in this bottom plate 106, and this end below is provided with cushion block 119, and these cushion block 119 usefulness screws 120 lock onto this bottom plate 106, to fix this core_pulling pole 118.

Please continue to consult Fig. 2 and Fig. 4, be respectively and eject the generalized section of product and first time that the novel secondary of the utility model ejects forced demoulding mechanism the action schematic diagram.After product 10 injection mo(u)ldings are finished, master mold 101 is opened with male model 102, the push rod of injection moulding board (figure do not show) stretches into bottom plate 106 and ejects and ejects hole 109 in the board 105,108, to go up, following liftout plate 103,104 jack-up, eject board 105 by shutter 122 and last, following liftout plate 103,104 link together, also can move upward thereupon, in the process that rising ejects, be fixed on core_pulling pole 118 transfixions on the bottom plate 106, being fixed on push rod 111 that ejects board 105 and the sleeve 116 that is fixed on upper ejector plate 103 ejects product 10, make the barb 30 of product 10 break away from core_pulling pole 118 ends, finish the pressure of barb 30 and deviate from.

Please continue to consult Fig. 2 and Fig. 5, be respectively and eject the generalized section of product and second time that the novel secondary of the utility model ejects forced demoulding mechanism the action schematic diagram.Eject for the first time after action finishes, be fixed on the limited post 110 that ejects on the board 105 and prop up the bottom surface of male model plate 102, on the push rod of injection moulding board (figure does not show) continues to promote, following liftout plate 103,104, and the clamp force of shutter 122 is less than the thrust of injection moulding board push rod, force shutter 122 to break away from, following liftout plate 103,104, separately eject board 105, make, following liftout plate 103,104 can continue to move upward, the sleeve 116 that is fixed on the upper ejector plate 103 ejects in the process in rising, the barb 20 of product 10 is forced to deviate from from jacking block 114, withdraw from all barbs of product 10.

The above is preferred embodiment of the present utility model only, is not to be used for limiting practical range of the present utility model; Every equivalence of doing according to the utility model changes and revises, and is all covered by the scope of the utility model claims.
