Specific embodiment
Make specific introduction to the present invention below in conjunction with the drawings and specific embodiments.
It is capable of the ejection die of fast assembling-disassembling and no ejector retainner plate, including：Die 1, oil cylinder 8, the male template 9 of die 1 is accommodated,
Caster, is assembled in die 1 and can depart from the slanted kicking block 3 of product snap fit, be locked on hot runner manifold 10 and be fixed on slanted kicking block 3
8 piston rod of oil cylinder, be connected to the taper pin 2 of slanted kicking block 3 ejecting product.It should be noted that with 2 ejecting product of taper pin be for
Disengaging product snap fit, ejecting product.There are the interior apertura lateralis inconsistent with die sinking direction or side recessed on plastic, we term it card
Hook.Using die sinking campaign or the ejection active force of molding, taper pin 2 is made to produce relative motion trend with product, taper pin 2 has die sinking side
To and horizontal direction two kinds of forms of motion, horizontal direction depart from overhead kick.
Pushing block is provided between slanted kicking block 3 and taper pin 2；Preferred as one kind, pushing block is L-type pushing block 4.The letter of 4 structure of L-type pushing block
Clean, processing is simple, cost-effective, fast and effeciently adjustment length can exit distance meet taper pin 2；L-type pushing block 4 passes through spiral shell
Silk is fixed on slanted kicking block 3.
The present invention eliminates two pieces of ejector retainner plates on mould, in the structure without ejector retainner plate, using being locked in hot runner manifold
8 piston rod of oil cylinder on 10 promotes slanted kicking block 3, the ejection that slanted kicking block 3 is completed by the drive taper pin 2 of L-type pushing block 4.
Ejection die, also includes：Be fixed in male template 9 and spacing slanted kicking block 3 locating part；As a kind of preferred, limit
Position part is guide rail 6；Using guide rail 6 not only can material-saving, and to slanted kicking block 3 ejection when have guide effect.Guide rail 6 leads to
Cross press strip 7 to be fixed on slanted kicking block 3, guide rail 6 is screwed in male template 9.
The concrete installation process of ejection die is：
As shown in figure 1, before being ejected, first assembling mould, it is that taper pin 2 and die 1 are assembled in one first
Rise, then L-type pushing block 4 and the die 1 for assembling are mounted in male template 9, then the oblique top being fixed together by contiguous block 5
Block 3 is mounted in male template 9, before slanted kicking block 3 is put in male template 9, guide rail 6 is fixed on slanted kicking block 3 by press strip 7
On, then it is fixed together by key screw slanted kicking block 3 and L-type pushing block 4, then male template 9 is fixed on by key screw guide rail 6
On, finally slanted kicking block 3 is fixed together by screw and 8 piston rod of oil cylinder and completes ejection.
As shown in Fig. 2 mould feature die separates, oil cylinder 8 promotes piston rod by oil-feed, piston rod be by screw and oblique
Jacking block 3 is fixed together, and piston rod movement just drives slanted kicking block 3 to move；Slanted kicking block 3 is fixed further through screw and L-type pushing block 4
Together, taper pin 2 is again on L-type pushing block 4, so 8 oil-feed of oil cylinder promotes piston rod, piston rod drives slanted kicking block 3 and taper pin 2
Ejecting product is completed together.Slanted kicking block 3 is limited by being fixed on 9 upper rail 6 of male template, while ejection also backward
Move back, so the package power of product can be reduced with 3 ejecting product of slanted kicking block.
The present invention provides a kind of ejection die for being capable of fast assembling-disassembling no ejector retainner plate slanted kicking block 3, simple for structure, processing letter
Single, can save upper and lower ejector retainner plate, square iron, back stitching, EGP, EGB, support, the parts such as rubbish nail, so as to effectively reduce mould thickness
And cost-effective, it is long more effectively to solve hot-runner nozzle, and colloidal sol storage is too many, and causes plastic material carbonization to decompose,
So as to improve the quality of Injection Molding Products.
The basic principles, principal features and advantages of the present invention have been shown and described above.The technical staff of the industry should
Understand, the invention is not limited in any way for above-described embodiment, all obtained by the way of equivalent or equivalent transformation
Technical scheme, all falls within protection scope of the present invention.
