Technical field
The utility model relates to mechanical field, particularly relates to a kind of easy-disassembling-assembling injection mold of producing for the injection mold of center type inclined pin structure.
Background technology
When the injection molding plastic inboard different from folding mould direction or the outside have hole, depression or boss (being commonly referred to overhead kick), on mould, slide block mechanism or the Slanting pin mechanism that can be displaced sideways must be made by the forming part place, the common form of taper pin has thimble-type taper pin (two-part, namely taper pin body and taper pin pull bar form), oblique pin base formula taper pin and mother plate inclined pin etc.Oblique pin base formula taper pin motion steadily, but because oblique pin base is fixed on upper ejector plate, it is large that oblique pin base accounts for the liftout plate space, not too applicable for the occasion that taper pin in mould is more.And the T-slot that the thimble-type taper pin is connected with taper pin by thimble (claiming the taper pin pull bar) connects motion, than oblique pin base formula taper pin, the thimble-type taper pin is at the male model plate and the liftout plate occupied area is little and the space is less, each taper pin is produced interferes, thereby have in the injection mold of overhead kick in treatment product, usually pay the utmost attention to and adopt the thimble-type taper pin.
Although the thimble-type taper pin has the characteristics such as the template of accounting for space is little, motion is flexible, but when mold attaching/detaching, need taper pin pull bar half-twist could be realized being connected with taper pin separation and connection, therefore how to improve to facilitate the dismounting of pull bar on mould structure, have great significance for improving mould packaging efficiency, reduction bench work amount etc.
The utility model content
The technical problem that the utility model mainly solves is to provide a kind of easy-disassembling-assembling injection mold, the return pin that can facilitate the dismounting of taper pin pull bar and design is improved structure, can greatly improve the mould packaging efficiency, reduce the bench work amount, the injection mold structure that significantly reduces production costs simultaneously.
for solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of easy-disassembling-assembling injection mold is provided, comprise caster, the male model plate, ejecting mechanism and resetting-mechanism, mother module core and the male die core of difference installation forming between described caster and male model plate, thimble and taper pin pull bar are equipped with in described male die core bottom, thimble and taper pin pull bar are arranged on respectively on upper ejector plate, be provided with resetting-mechanism between described male model plate and ejecting mechanism, described resetting-mechanism comprises return pin and back-moving spring, described return pin comprises release link and the base that resets, the described base that resets is located in upper ejector plate, release link is passed upper ejector plate and male model plate, described release link upper end is provided with screw thread, the described base that resets is the U-shaped shoulder, side plane and the release link of the U-shaped shoulder of the described base that resets are tangent.
Preferably, described back-moving spring is arranged between male model plate and upper ejector plate.
Preferably, the upper surface of described release link flushes with the upper surface of male model plate.
Preferably, described ejecting mechanism comprises upper ejector plate and the lower liftout plate of installing from top to bottom, and upper ejector plate and lower liftout plate are installed between male model plate and die shoe successively, and the lower surface of the base that resets flushes with the lower surface of upper ejector plate.
The beneficial effects of the utility model are: the utility model is a kind of easy-disassembling-assembling injection mold, can greatly improve the mould packaging efficiency, reduce the bench work amount, the injection mold structure that significantly reduces production costs simultaneously.After this scheme adopts and will assemble, concordant with male model plate top release link end processes one section screwed hole, become the U-shaped shoulder with the concordant base designs that resets in upper ejector plate bottom surface after assembling simultaneously, side plane and the release link of U-shaped shoulder are tangent, the locating hole of base U-shaped shoulder of resetting accordingly on upper ejector plate is designed to rectangular shape, prevents the rotation of return pin when the taper pin pull bar is screwed out.Adopt this return pin structure, the dismounting of thimble-type taper pin is simplified, the packaging efficiency of mould is enhanced about more than once, thereby die manufacturing cost is reduced greatly.

The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made more explicit defining.
See also Fig. 1 to Fig. 3, the utility model embodiment comprises:
a kind of easy-disassembling-assembling injection mold, comprise caster 1, male model plate 5, ejecting mechanism and resetting-mechanism, mother module core 2 and the male die core 3 of difference installation forming between described caster 1 and male model plate 5, ejecting mechanism comprises upper ejector plate 7 and the lower liftout plate 8 of installing from top to bottom, upper ejector plate 7 and lower liftout plate 8 are installed between male model plate 5 and die shoe 9 successively, mould pin 10 is arranged between male model plate 5 and die shoe 9, resetting-mechanism comprises return pin 4 and back-moving spring 6, described return pin 4 comprises release link 41 and the base 42 that resets, the described base 42 that resets is located in upper ejector plate 7, the reset lower surface of base 42 flushes with the lower surface of upper ejector plate 7, release link 41 is passed upper ejector plate and male model plate 5, the upper surface of release link 41 flushes with the upper surface of male model plate 5, described release link 41 upper ends are provided with screw thread, the described base 42 that resets is the U-shaped shoulder, side plane and the release link 41 of the U-shaped shoulder of the described base 42 that resets are tangent, back-moving spring 6 is arranged between male model plate 5 and upper ejector plate 7.
