Description

Simple and easy secondary liftout attachment
Technical field
The present invention relates to a kind of simple and easy secondary liftout attachment.
Background technology
In the plastic product, tending to some back-off structure can not need the side to loose core the demoulding, and directly adopts forced stripper mechanism, and in most cases, the action of forced stripper mechanism needs secondary to eject to realize.Traditional secondary ejects action and often relies on four ejector retainner plates on the mould to realize, and the structure of four ejector retainner plates can increase the gross thickness and the complexity of mould virtually.
Summary of the invention
The objective of the invention is to overcome the deficiency that prior art exists, a kind of simple and easy secondary liftout attachment is provided.
The object of the invention is realized through following technical scheme:
Simple and easy secondary liftout attachment comprises base plate, moving platen and first thimble, and said moving platen upper end is equipped with mavable module core; It is characterized in that: have groove on the said base plate; Spring one end is installed in the groove, and the cup head of the said first thimble lower end has blind hole, and the spring other end is installed in the blind hole of first thimble; Ejector retainner plate with cup head coupling is installed on the cup head of first thimble; The ejector retainner plate upper end is equipped with the face needle plate, and said first thimble runs through ejector retainner plate, face needle plate, moving platen and mavable module core, and the other end of ejector retainner plate is equipped with second thimble; Second thimble runs through face needle plate, moving platen and mavable module core, and ejector retainner plate and face needle plate are installed in base plate and the moving platen.
Further, above-mentioned simple and easy secondary liftout attachment, wherein, first thimble runs through the diameter of upper end of mavable module core less than the diameter that runs through ejector retainner plate, face needle plate and moving platen middle-end, lower end, and runs through the length that the thimble length of mavable module core is longer than mavable module core.
Further, above-mentioned simple and easy secondary liftout attachment wherein, is fixed with pilot pin respectively in groove and the blind hole.
The substantive distinguishing features of technical scheme of the present invention is mainly reflected in progressive:
When the present invention utilizes injection machine to eject action, face needle plate and ejector retainner plate are ejected, together eject thereby drive second thimble; First thimble ejects under spring action simultaneously, and up to pushing up the mavable module core bottom, first thimble stops to eject; And second thimble continues to eject under the ejector retainner plate effect; Product is broken away from, practiced thrift the amount number of ejector retainner plate, cause and practiced thrift cost.
Description of drawings
Below in conjunction with accompanying drawing technical scheme of the present invention is described further:
Fig. 1: the organigram after not having thimble to eject of the present invention;
Fig. 2: the organigram after first thimble of the present invention ejects;
Fig. 3: the present invention accomplishes the organigram after ejecting.
The specific embodiment
As shown in Figure 1, simple and easy secondary liftout attachment comprises base plate 9, moving platen 3 and first thimble 1; Moving platen 4 upper ends are equipped with mavable module core 3, have groove on the base plate 9, and spring 8 one ends are installed on the groove; The cup head of first thimble, 1 lower end has blind hole; Spring 8 other ends are installed in the blind hole of first thimble 1, are equipped with on the cup head of first thimble 1 and glass ejector retainner plate 6 of head coupling, and ejector retainner plate 6 upper ends are equipped with face needle plate 5; First thimble 1 runs through ejector retainner plate 6, face needle plate 5, moving platen 4 and mavable module core 3; The other end of ejector retainner plate 6 is equipped with second thimble, 2, the second thimbles 2 and runs through face needle plate 5, moving platen 4 and mavable module core 3, and ejector retainner plate 6 is installed in base plate 9 and the moving platen 4 with face needle plate 5; First thimble 1 runs through the upper end diameter of mavable module core 3 less than the diameter that runs through ejector retainner plate 6, face needle plate 5 and moving platen 4 middle-ends, lower end, and runs through the length that the thimble length of mavable module core 3 is longer than mavable module core 3; Be separately installed with pilot pin 7 in groove and the blind hole.
During concrete the application, shown in Figure 2, after the die sinking; Injection machine begins to eject action, and face needle plate 5 and ejector retainner plate 6 are ejected, and drives second thimble 2 and ejects together; First thimble 1 ejects under the effect of spring 8 once more, upwards rises to by the bottom of mavable module core 3 up to first thimble 1 and blocks, and stops to eject; Face needle plate 5 continued to eject and drove second thimble 2 with ejector retainner plate 6 and continues to eject this moment, and as shown in Figure 3, ejector retainner plate 6 continues to drive second thimble 2 to rising and upwards ejects; The back-off position of product this moment in first thimble 1 will produce elastic deformation, force to break away from first thimble 1, accomplish the whole process that ejects then.
It is emphasized that: above only is preferred embodiment of the present invention; Be not that the present invention is done any pro forma restriction; Every foundation technical spirit of the present invention all still belongs in the scope of technical scheme of the present invention any simple modification, equivalent variations and modification that above embodiment did.
