On body, holding block perforating insertion is opened in house the pouring head on the first noumenon, and first holding block, which is worn, to be passed through
The holding block perforating, second holding block are arranged in this mould towards in the one side of the bed die.The bed die include the second body,
Be arranged on the second intrinsic injection molding cavity, the neighbouring injection molding cavity is set and be slidably arranged in this second intrinsic first
Sliding part and the second sliding part being connected on first sliding part, second holding block support first sliding part to promote this
First sliding part slides, and second sliding part includes the fixed block being removably disposed on first sliding part and slidably set
The second sliding shoe in the fixed block is put, the injection orifice connected with the injection molding cavity is offered on the fixed block, second slip
Block include to should the support division that sets of injection orifice, the pouring head includes hollow guide bar, the conduit that is connected with the guide bar
And the Jiao Kou being connected with the conduit, the Jiao Kou are housed in the injection orifice, the support division is slidably supported on the Jiao Kou.
Injection mold provided by the invention includes backform, middle mould and bed die, and entrance aperture is offered on backform and first is supported
Block, offers pouring head perforating, holding block perforating and the second holding block on middle mould, and pouring head, which is worn, to be housed in pouring head and wear
In apertured, including guide bar, conduit and Jiao Kou, guide bar corresponds to entrance aperture setting, bed die include injection molding cavity, the first sliding part and
Second sliding part, the first sliding part are set adjacent to injection molding cavity, and the second sliding part includes being detachably connected on the first sliding part
Fixed block and the second sliding shoe that is slidably arranged on fixed block, offer the injection connected with injection molding cavity on fixed block
Hole, the second sliding shoe include support division, and support division corresponds to injection orifice setting, and Jiao Kou is housed in injection orifice, the second sliding shoe to
Slided close to the direction of injection molding cavity, support division is supported in Jiao Kou with fixing glue mouth, so as to avoid flash problem, effective lifting workpieces
Molding effect；When taking gum outlet, the second sliding shoe is slided so that support division is gradually distance from Jiao Kou to the direction away from injection molding cavity,
So as to being Jiao Kou when departing from injection orifice, there is provided larger disengaging space, avoid Jiao Kou from being limited in injection orifice interior and cause glue
