It holds on fixed block 341.
Referring to FIG. 4, pouring head 40 includes guide item 41, conduit 42 and glue mouth 43.Material is flowed to through entrance aperture 12 and is led
In material strip 41, then through guide item 41 into conduit 42, glue mouth 43 is set to the one end of conduit 42 far from guide item 41, is used for output
Material.Glue mouth 43 is ox horn shape, the area of cross section from one end close to conduit 42 to the other end far from conduit 42 gradually
Reduce.
It please also refer to Fig. 5 and Fig. 6, when 100 mold-closing injection of injection mold, firstly, pouring head 40, which is worn, is housed in middle mould
In 20, glue mouth 43 exposes outside middle mould 20, and middle mould 20 is gradually placed on bed die 30 later, and the second holding block 25 passes through second
It supports inclined-plane 251 and gradually supports the first inclined-plane 3312 on the first sliding shoe 331, to make the first sliding shoe 331 gradually to leaning on
The direction sliding of nearly injection molding cavity 321, mould 20 is supported completely when on bed die 30 and relative to 30 stop motion of bed die in the middle, glue
Mouth 43 is housed in injection orifice 3412.Secondly, backform 10 is gradually placed on middle mould 20, the first holding block 13 is worn in
Holding block perforating 24 on mould 20 simultaneously supports on the second inclined-plane 3422 of the second sliding shoe 342, to make the second sliding shoe
342 gradually slide to the direction close to injection molding cavity 321, when backform 10 is supported completely on middle mould 20 and is stopped relative to middle mould 20
When only moving, support division 3421 is supported on glue mouth 43, thus fixed glue mouth 43.It is poured finally, material enters through entrance aperture 12
First 40, and enter injection molding cavity 321 through glue mouth 43, thus injection molding workpiece (not shown).Since glue mouth 43 is preferably fixed,
Therefore flash problem can be effectively prevented from.
When the die sinking of injection mold 100 takes workpiece, firstly, backform 10 is gradually therefrom removed on mould 20, the first holding block
The first of 13 supports the second inclined-plane 3422 that inclined-plane 131 progressively disengages the second sliding shoe 342, and the second sliding shoe 342 is in the second bullet
Property part 3424 supporting under, gradually to being moved far from the direction of injection molding cavity 321 so that support division 3421 is gradually distance from glue mouth 43,
To be glue mouth 43 when being detached from injection orifice 3412, biggish disengaging space is provided, glue mouth 43 is avoided to be limited in injection orifice
Glue mouth 43 is caused to be broken when being detached from injection orifice 3412 in 3412.Secondly, middle mould 20 is gradually removed from bed die 30,
Glue mouth 43 progressively disengages injection orifice 3412, and the second of the second holding block 25 supports inclined-plane 251 and progressively disengage the first sliding shoe later
The first inclined-plane 3312 on 331 so that the first sliding shoe 331 be made gradually to slide to the direction far from injection molding cavity 321, and then drives
Fixed block 341 is moved to the direction far from injection molding cavity 321, and the die sinking of injection mold 100 is completed with this.Finally, injection molding is completed
Workpiece taken out out of injection molding cavity 321.
Injection mold 100 provided by the present invention includes backform 10, middle mould 20 and bed die 30, offers incidence on backform 10
Hole 12 and the first holding block 13 offer pouring head perforating 23, holding block perforating 24 and the second holding block 25 on middle mould 20,
Pouring head 40, which is worn, to be housed in pouring head perforating 23, including guide item 41, conduit 42 and glue mouth 43, and guide item 41 corresponds to
Perforation 12 is arranged, and bed die 30 includes injection molding cavity 321, the first sliding part 33 and the second sliding part 34, the neighbouring note of the first sliding part 33
It moulds chamber 321 to be arranged, the second sliding part 34 includes the fixed block 341 being detachably connected on the first sliding part 33 and slidably sets
The second sliding shoe 342 on fixed block 341 is set, the injection orifice 3412 being connected to injection molding cavity 321 is offered on fixed block 341,
The second sliding shoe 342 includes support division 3421, and the corresponding injection orifice 3412 of support division 3421 is arranged, and glue mouth 43 is housed in injection orifice
In 3412, the second sliding shoe 342 is slided to the direction close to injection molding cavity 321, and support division 3421 is supported in glue mouth 43 to fix glue
Mouth 43, so that flash problem is avoided, the molding effect of effective lifting workpieces;When taking gum outlet 43, the second sliding shoe 342 is to separate
The direction of injection molding cavity 321 is slided so that support division 3421 is gradually distance from glue mouth 43, to be detached from injection orifice 3412 for glue mouth 43
When, biggish disengaging space is provided, glue mouth 43 is avoided to be limited in injection orifice 3412 and glue mouth 43 is caused to be detached from injection orifice
It is broken when 3412, avoids the generation of pressing mold phenomenon, thus the further molding effect of lifting workpieces.
