Description

Injection mold
Technical field
The present invention relates to a kind of injection mold, more particularly to the injection mold that a kind of pouring head is not easily broken.
Background technology
In injection molding art, to realize the injection molding of workpiece, existing processing procedure is usually that pouring head is placed in mould, it Afterwards by mould matched moulds, plastic cement etc. is molded into the die cavity of mould by pouring head.Typically it is separately provided with traditional pouring head One section of runner, passes through runner injection moulding plastic etc..However, the setting of runner easily causes the increase of mould injection pressure, Plastic cement is set to overflow and form waste material, and runner easily fractures from pouring head and come off, and mould pressing mold risk is present, so as to shadow The shaping of workpiece is rung, causes the effect of Workpiece shaping poor.
The content of the invention
In view of this, it is necessary to which a kind of preferable injection mold of Workpiece shaping effect is provided.
A kind of injection mold, including backform, middle mould and bed die, mould is arranged between the backform and the bed die in this.The note Mould also includes wearing the pouring head being housed in this in mould, and the backform includes entrance aperture and the first holding block, the entrance aperture For the injection molding material of water conservancy diversion, first holding block is arranged on the backform towards in the one side of mould in this.Mould includes the in this One body, pouring head perforating, holding block perforating and the second holding block, pouring head perforating insertion are opened in the first 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 Mouth is broken when departing from injection orifice, avoids the generation of pressing mold phenomenon, so as to the molding effect of further lifting workpieces.
