Description

Injection mold
Technical field
The present invention relates to a kind of injection mold more particularly to a kind of injection molds that pouring head is not easily broken.
Background technique
In injection molding art, for the injection molding for realizing workpiece, existing processing procedure is usually that pouring head is placed in mold, it Afterwards by mold clamping, the type that plastic cement etc. is molded into mold by pouring head is intracavitary.It is generally separately provided on traditional pouring head One section of runner, passes through runner injection moulding plastic etc..However, the setting of runner is easy to cause the increase of mold injection pressure, Plastic cement is set to overflow and form waste material, and runner is easy to fracture from pouring head to fall off, making mold, there are pressing mold risks, thus shadow The molding for ringing workpiece, causes the effect of workpiece shaping poor.
Summary of the invention
In view of this, it is necessary to provide a kind of preferable injection molds of workpiece shaping effect.
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 further includes wearing the pouring head being housed in this in mould, which includes entrance aperture and the first holding block, the entrance aperture For the injection molding material of water conservancy diversion, which is arranged in the backform towards in the one side of mould in this.Mould includes the in this One ontology, pouring head perforating, holding block perforating and the second holding block, pouring head perforating perforation are provided with the first To accommodate the pouring head on body, holding block perforating perforation is provided on the first noumenon, which, which wears, passes through Mould is arranged in this towards in the one side of the bed die in the holding block perforating, second holding block.The bed die include the second ontology, Setting the second intrinsic injection molding cavity, the neighbouring injection molding cavity be arranged 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 push this The sliding of first sliding part, second sliding part include the fixed block being removably disposed on first sliding part and slidably set The second sliding shoe in the fixed block is set, the injection orifice being connected to the injection molding cavity is offered on the fixed block, second sliding Block includes the support division of corresponding injection orifice setting, which includes hollow guide item, the conduit that connect with the guide item And the Jiao Kou connecting with the conduit, the Jiao Kou are housed in the injection orifice, which slidably supports 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 item, conduit and Jiao Kou, guide item corresponds to entrance aperture setting, bed die include injection molding cavity, the first sliding part and Second sliding part, the first sliding part are arranged 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 being connected to 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 It being slided close to the direction of injection molding cavity, support division is supported in Jiao Kou to fix Jiao Kou, so that flash problem is avoided, effective lifting workpieces Molding effect;When taking gum outlet, the second sliding shoe is slided to the direction far from injection molding cavity so that support division is gradually distance from Jiao Kou, To be Jiao Kou when being detached from injection orifice, biggish disengaging space is provided, Jiao Kou is avoided to be limited in injection orifice and lead to glue Mouth is broken when being detached from injection orifice, avoids the generation of pressing mold phenomenon, thus the further molding effect of lifting workpieces.
