Description
Technical field
The present invention relates to mechanical field, particularly relate to a kind of return pin modified node method being easy to mold attaching/detaching in producing for the injection mold with center type inclined pin structure.
Background technology
The inner side different from folding mould direction when injection molding plastic or outside have hole, depression or boss time (being commonly referred to overhead kick), on mould, the slide block mechanism or Slanting pin mechanism that can be displaced sideways must be made by forming part place, the common form of taper pin has thimble-type taper pin (two-part, i.e. taper pin body and taper pin pull bar composition), taper pin A seating taper pin and mother plate inclined pin etc.Taper pin A seating taper pin stable movement, but be fixed on upper ejector plate due to oblique pin base, it is large that oblique pin base accounts for liftout plate space, and the occasion more for taper pin in mould is not too applicable.And thimble-type taper pin carries out being connected motion by the T-slot that thimble (also known as taper pin pull bar) and taper pin coordinate, compared to taper pin A seating taper pin, thimble-type taper pin is in male template and liftout plate occupied area is little and space is less, each taper pin can not be made to produce interfere, thus have in the injection mold of overhead kick in treatment product, usually pay the utmost attention to and adopt thimble-type taper pin.
Although thimble-type taper pin has and accounts for that templatespace is little, the feature such as flexible of moving, but when mold attaching/detaching, taper pin pull bar half-twist could need be realized and being separated and connection of taper pin, therefore on mould structure, how to carry out the dismounting improving to facilitate pull bar, raising mould packaging efficiency, reduction bench work amount etc. are had great significance.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of return pin modified node method being easy to mold attaching/detaching, the dismounting of taper pin pull bar can be facilitated and the return pin modified node method designed, greatly can improve mould packaging efficiency, reduce bench work amount, significantly reduce the injection mold structure of production cost simultaneously.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of return pin modified node method being easy to mold attaching/detaching, comprise caster, male template, ejecting mechanism and resetting-mechanism, mother module core and the male die core of installation forming is distinguished between described caster and male template, thimble and taper pin pull bar are housed bottom described male die core, thimble and taper pin pull bar are arranged in upper ejector plate respectively, resetting-mechanism is provided with between described male template and ejecting mechanism, described resetting-mechanism comprises return pin and back-moving spring, described return pin comprises release link and reset base, described reset base is located in upper ejector plate, release link is through upper ejector plate and male template, described release link upper end is provided with screw thread, described reset base is U-shaped shoulder, side plane and the release link of the U-shaped shoulder of described reset base are tangent.
Preferably, described back-moving spring is arranged between male template and upper ejector plate.
Preferably, the upper surface of described release link flushes with the upper surface of male template.
Preferably, described ejecting mechanism comprises the upper ejector plate and lower liftout plate installed from top to bottom, and upper ejector plate and lower liftout plate are installed between male template and die shoe successively, and the lower surface of reset base flushes with the lower surface of lower liftout plate.
The invention has the beneficial effects as follows: the present invention is a kind of return pin modified node method being easy to mold attaching/detaching, greatly can improve mould packaging efficiency, reduce bench work amount, significantly reduce the injection mold structure of production cost simultaneously.The program adopts processes one section of screwed hole by the release link end concordant with male template top after assembling, the reset base designs concordant with upper ejector plate bottom surface after assembling is become U-shaped shoulder simultaneously, side plane and the release link of U-shaped shoulder are tangent, on upper ejector plate, the locating hole of corresponding reset base U-shaped shoulder is designed to rectangular shape, prevents the rotation of the return pin when being screwed out by taper pin pull bar.Adopt this return pin structure, the dismounting of thimble-type taper pin can be made to be simplified, and the packaging efficiency of mould is enhanced about more than once, thus die manufacturing cost is reduced greatly.

Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Refer to Fig. 1 to Fig. 3, the embodiment of the present invention comprises:
A kind of return pin modified node method being easy to mold attaching/detaching, comprise caster 1, male template 5, ejecting mechanism and resetting-mechanism, mother module core 2 and the male die core 3 of installation forming is distinguished between described caster 1 and male template 5, ejecting mechanism comprises the upper ejector plate 7 and lower liftout plate 8 installed from top to bottom, upper ejector plate 7 and lower liftout plate 8 are installed between male template 5 and die shoe 9 successively, mould pin 10 is arranged between male template 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 reset base 42, described reset base 42 is located in upper ejector plate 7, the lower surface of reset base 42 flushes with the lower surface of upper ejector plate 7, release link 41 is through upper ejector plate and male template 5, the upper surface of release link 41 flushes with the upper surface of male template 5, described release link 41 upper end is provided with screw thread, described reset base 42 is U-shaped shoulder, side plane and the release link 41 of the U-shaped shoulder of described reset base 42 are tangent, back-moving spring 6 is arranged between male template 5 and upper ejector plate 7.
When dismantling the taper pin pull bar of dynamic model part, first die shoe 9, mould pin 10 and lower liftout plate 8 are removed, then by the pressure plate tool that pincers worker is special, by the screw in pressing plate being screwed into the screwed hole of return pin 4 front end, to be threaded in process under the effect of back-moving spring 6, upper ejector plate 7 upwards moves towards the direction of male template 5, and the back-moving spring 6 of taper pin pull bar mounting portion is arranged between male template 5 and upper ejector plate 7.U-shaped shoulder exposes the bottom surface of upper ejector plate, itself and taper pin now just can be made by taper pin pull bar half-twist to depart from, thus realize the dismounting of taper pin pull bar, so that follow-up mould repairs a die and the work such as dismounting.
