The specific embodiment
See also Fig. 1, the injection molding apparatus 100 of embodiment of the present invention comprises male model 20 and the master mold 30 that matches with male model 20.Male model 20 and master mold 30 form a die cavity (figure does not show) jointly behind matched moulds, through the plastics of injection fusion in this die cavity, and through cooling forming, can obtain the injection mo(u)lding article adaptive with cavity shape.In this embodiment, injection molding apparatus 100 is a horizontal injection molding equipment, promptly male model 20 moves in the horizontal direction and carries out matched moulds and die sinking, has omitted the clamping that promotes male model 20 and injection device etc. among the figure, and these are known technology, do not give unnecessary details at this.
Please be simultaneously referring to Fig. 2, master mold 30 comprises and a mother module core 31 and a master mold liftout attachment 40 that is oppositely arranged with male model 20.Master mold liftout attachment 40 comprises a solid plate 41 and two ejecting mechanisms 42.Mother module core 31 is fixedly set in solid plate 41 1 sides.Solid plate 41 offers a plurality of installing holes 410, is used for being fixedly connected with mother module core 31.
Each ejecting mechanism 42 comprise be opened in solid plate 41 accommodate recess 411; With accommodate that recess 411 cooperates and with the solid plate 41 common seals 413 that form a seal chamber 412; Slip is arranged at the piston 414 in the seal chamber 412; Be connected and be arranged in the ejector 415 of seal 413 and the pipeline 416 that is opened in solid plate 41 and is connected with seal chamber 412 with piston 414.Through pipeline 416 is communicated with pneumatic supply or oil pressure source, air pressure capable of using or oil pressure actuated piston 414 and ejector 415 move, and eject action to accomplish in master mold 30 sides.
During 40 actions of master mold liftout attachment, ejector 415 along continuous straight runs switch between the primary importance and the second place.When ejector 415 was in primary importance, ejector 415 stretched out to eject action from solid plate 41.When ejector 415 is in the second place, ejector 415 rollbacks and being contained in the solid plate 41.That is to say that when ejector 415 was in the second place, ejecting mechanism 42 was hidden in the solid plate 41, thereby be failure to actuate when need not when master mold 30 1 sides are carried out liftout, can ejector 415 be contained in the solid plate 41, strengthened the flexibility of using.Preferable, when ejector 415 was in the second place, the ejection end face 4151 of ejector 415 is provided with solid plate 41 just accommodated the surperficial concordant of recess 411, thereby behind the ejecting mechanism 42, can not exert an influence with the surface that mother module core 31 combines to solid plate 41.In addition, seal chamber 412 and pipeline 416 all are formed in the solid plate 41, make overall structure more compact.
In this embodiment, injection molding apparatus 100 has an oil pressure source 101, and this oil pressure source 101 can be the oil pressure source that adopts in clamping or the injection device.Piston 414 is separated to form first cavity 4121 and second cavity 4122 with seal chamber 412.Pipeline 416 comprises first pipeline 4161 that is connected with first cavity 4121, and second pipeline 4162 that is connected with second cavity 4122.First pipeline 4161 and second pipeline 4162 are connected to the fuel-displaced port and the oil return port of oil pressure source 101 respectively, and the oil pressure actuated piston 414 of oil pressure source 101 slides in seal chamber 412, eject and fallback action thereby drive ejector 415 completion.Cause first pipeline 4161 and second pipeline 4162 are opened in the solid plate 41, and solid plate 41 is processed by metal material usually, and first, second pipeline 4161,4162 can bear bigger pressure.
In this embodiment, accommodate recess 411, and comprise installation portion 4112 that is formed at its open side and the main part 4113 that is connected with this installation portion 4112 towards mother module core 31.Piston 414 is located in the main part 4113, and the shape of cross section of the shape of cross section of piston 414 and main part 4113 is suitable, so that piston 414 moving axially along main part 4113.Main part 4113 is a cylinder.Seal 413 is fixedly set in installation portion 4112, and is tightly connected with installation portion 4112.Installation portion 4112 is the quadrangle groove, and seal 413 is and the suitable rectangular block of quadrangle groove.The end face of seal 413 and solid plate 41 form the surface co-planar of accommodating recess 411, thereby seal 413 can embed in the solid plate 41 fully, is convenient to install mother module core 31.Certainly, seal 413 also can be other shape adapting with installation portion 4112.Satisfy seal 413 and accommodate 411 salable connections of recess to get final product with the solid plate 41 common seal chambers 412 that form.
The quantity that is appreciated that ejecting mechanism 42 is not limited to two, can be provided with according to the actual position that ejects.Simultaneously, master mold liftout attachment 40 also can be applicable in the injection forming mold of vertical direction matched moulds, and ejects action in vertical direction.
It is understandable that those skilled in the art also can do other variation etc. and be used for design of the present invention in spirit of the present invention, as long as it does not depart from technique effect of the present invention and all can.These all should be included within the present invention's scope required for protection according to the variation that the present invention's spirit is done.
