Abstract
The technical solution of the utility model is a kind of ejector sleeve extension bar combining structure for being applied to injection mold product, including ejector sleeve, ejector sleeve fuse and ejector sleeve extension bar, external diameter of the internal diameter of ejector sleeve and ejector sleeve extension bar more than or equal to ejector sleeve fuse, it is internal after ejector sleeve and the assembling of ejector sleeve extension bar to be available for ejector sleeve fuse to pass through, a glass head is arranged at the ejector sleeve bottom, cup head is coaxial with ejector sleeve and cup head external diameter is more than ejector sleeve external diameter, the ejector sleeve extension bar upper end is radially provided with T-slot, and cup head snaps in rear ejector sleeve and ejector sleeve extension bar coaxial line in T-slot.The utility model is split type by what existing ejector sleeve made into ejector sleeve and ejector sleeve extension bar combine, so that being reduced per segment length, and then cause that equal external diameter and the ejector sleeve strength and stiffness and axial bearing capacity of wall thickness are lifted, do not allow when mould is produced and ejected fragile, even and if damage, only need to change ejector sleeve, change convenient and swift.
Description
Technical field
The utility model is related to injection mold field, is lengthened more particularly, to a kind of ejector sleeve for being applied to injection mold product
Bar combining structure.
Background technology
During Design of Plastic Mould, we are frequently seen the screw mounting post of product, i.e., two products are by beating
Screw is installed together, but is made up of hundreds of parts in a complete product, and their assembly relation is a lot
Screw is all used and rod structure has been installed.Ejector sleeve and ejector sleeve fuse will be designed substantially on mould for such screw mounting post
Structure auxiliary ejection, as shown in Fig. 2 ejection ejector sleeve can participate in formed product every time when, mould is by repeatedly production meeting
Cause not only thin but also long ejector sleeve to damage deformation, cause ejection to have some setbacks, eject situations such as killing, gently then damage product and ejector sleeve, weight
Repairing mould is then needed, is taken time and effort, the normal production of influence.
Utility model content
Regarding to the issue above, the utility model provides a kind of ejector sleeve extension bar combination knot for being applied to injection mold product
Structure, it makes ejector sleeve split type so that every section of length of ejector sleeve is reduced, and then causes the ejector sleeve intensity of equal external diameter and wall thickness
Lifted with rigidity and axial bearing capacity, do not allow when mould is produced and ejected it is fragile, even and if damage, it is only necessary to
Ejector sleeve part is changed, is changed convenient and swift.
The technical solution of the utility model is a kind of ejector sleeve extension bar combining structure for being applied to injection mold product, including
The internal diameter of ejector sleeve, ejector sleeve fuse and ejector sleeve extension bar, ejector sleeve and ejector sleeve extension bar more than or equal to ejector sleeve fuse external diameter, ejector sleeve and
Internal after the assembling of ejector sleeve extension bar to be available for ejector sleeve fuse to pass through, a glass head arranged at the ejector sleeve bottom, and cup head is coaxial with ejector sleeve and cup head
External diameter is more than ejector sleeve external diameter, and the ejector sleeve extension bar upper end is radially provided with T-slot, cup head snap in T-slot after ejector sleeve with push away
Pipe extension bar coaxial line.
Preferably, the ejector sleeve extension bar external diameter of the ejector sleeve is more than ejector sleeve external diameter, and the cup head is snapped in be located at after T-slot and pushed away
Inside pipe extension bar.
Preferably, coaxial line after the ejector sleeve and ejector sleeve extension bar are assembled.
The utility model is split type by the way that ejector sleeve made so that every section of length of ejector sleeve is reduced, and then causes equal outer
The ejector sleeve strength and stiffness of footpath and wall thickness are lifted, mould produce eject when do not allow it is fragile, even and if damage, only need
Ejector sleeve part is changed, is changed convenient and swift.
Brief description of the drawings
Fig. 1 is the structural representation that the utility model is applied in the product；
Fig. 2 is the structural representation of existing ejector sleeve and ejector sleeve fuse；
Fig. 3 is structural representation of the present utility model；
Fig. 4 is the structure decomposition figure of Fig. 3；
Wherein：1-ejector sleeve；2-ejector sleeve fuse；3-ejector sleeve extension bar；4-cup head；5-T-slot.
Specific embodiment
Below in conjunction with the accompanying drawings, the utility model is described in further detail.
Shown as shown in Figure 1, Figure 3 and Figure 4, the technical solution of the utility model is a kind of ejector sleeve for being applied to injection mold product
The internal diameter of extension bar combining structure, including ejector sleeve 1, ejector sleeve fuse 2 and ejector sleeve extension bar 3, ejector sleeve 1 and ejector sleeve extension bar 3 is more than
It is internal after ejector sleeve 1 and the assembling of ejector sleeve extension bar 3 to be available for ejector sleeve fuse 2 to pass through equal to the external diameter of ejector sleeve fuse 2, the bottom of the ejector sleeve 1
There is cup first 4 in portion, and cup first 4 is coaxial with ejector sleeve 1 and first 4 external diameter of cup is more than the external diameter of ejector sleeve 1, and the upper end of ejector sleeve extension bar 3 is radially
T-slot 5 is provided with, cup first 4 snaps in rear ejector sleeve 1 and the coaxial line of ejector sleeve extension bar 3 in T-slot 5.
Preferably, the external diameter of ejector sleeve extension bar 3 of the ejector sleeve 1 is more than the external diameter of ejector sleeve 1, after the cup first 4 snaps in T-slot 5
Inside ejector sleeve extension bar 3.
Preferably, coaxial line after the ejector sleeve 1 and ejector sleeve extension bar 3 are assembled.
When using, ejector sleeve 1 and ejector sleeve extension bar 3 are set in a mold, after product injection moulding, mould collaboration ejector sleeve 1
Product is ejected with ejector sleeve extension bar 3, realizes the process of the demoulding, the structure of this ejector sleeve 1 and the combination of ejector sleeve extension bar 3 relative to
The ejector sleeve of integral type, substantially increases the rigidity and intensity and axial bearing capacity of ejector sleeve so that ejector sleeve service life before
Increase substantially, and because the rigidity and intensity of ejector sleeve extension bar 3 are more than ejector sleeve 1, even if so there is abrasion or destroying
Situation, be also ejector sleeve 1 be destroyed, it is only necessary to by ejector sleeve 1 along T-slot 5 radial direction take out, change a new ejector sleeve 1
, it is convenient that whole process is changed.
The above, is only better embodiment of the present utility model, and any formal limit is not made to utility model
System, it is every according to know-why of the present utility model to any simple modification made for any of the above embodiments, equivalent variations or modification,
Still fall within the range of technical solutions of the utility model.
