A kind of IMD Banana gate die
Technical field
The utility model relates to a kind of IMD Banana gate die.
Background technology
IMD is a kind of surface decoration technique, generally comprises surface sclerosis transparent membrane, middle printing pattern layer and back side injection molded layers, in the middle of ink is placed on, can make product rub resistance, prevents that surface from being scratched, and can keep for a long time the distinctness of color to be difficult for fading.In actual production, need diaphragm to be placed in die cavity, often there will be diaphragm in die cavity, to be subject to trying hard to recommend of injection direction move and be shifted, cause defect rate higher, the utility model provides a kind of mould that enters glue from the diaphragm back side for this reason.
Utility model content
In order to address the above problem, the utility model provides a kind of IMD Banana gate die that enters glue from the diaphragm back side.
The utility model solves the technical scheme that its technical problem adopts:
A kind of IMD Banana gate die, comprising: patrix, be provided with one for the installation cavity of diaphragm is installed, and on patrix, be also provided with sprue gate and first passage, sprue gate is communicated with first passage, and first passage is positioned at installation cavity one side; Counterdie, is above provided with a second channel, and second channel entrance is communicated with first passage after matched moulds, and outlet is arranged on the position of corresponding installation cavity on counterdie.
Described second channel inner chamber is ox horn type, and large one end is entrance, and little one end is outlet.
The utility model also comprises some supplemental core, and supplemental core one end is plugged on counterdie, and the other end is positioned at installation cavity.
The beneficial effects of the utility model are: adopt the utility model of said structure by second channel is set, glue-feeder is set to the back side of diaphragm, when injection, sizing material first pushes down that the diaphragm back side is then in the arc-shaped can not produce lateral external forces to diaphragm to product surrounding diffusion, prevents diaphragm displacement.The utility model is simple in structure, practical.

The specific embodiment
With reference to Fig. 1~Fig. 5, the utility model is a kind of IMD Banana gate die, comprising: patrix 1, be provided with one for the installation cavity of diaphragm 5 is installed, on patrix 1, be also provided with sprue gate 2 and first passage, sprue gate 2 is communicated with first passage, and first passage is positioned at installation cavity one side; Counterdie 3, is above provided with a second channel 4, and second channel entrance 42 is communicated with first passage after matched moulds, and outlet 41 is arranged on the position of corresponding installation cavity on counterdie 3; Second channel 4 inner chambers are ox horn type, and large one end is entrance 42, and little one end is outlet 41.
Adopt the utility model of said structure by second channel 4 is set, glue-feeder is set to the back side of diaphragm 5, when injection, sizing material first pushes down that diaphragm 5 back sides are then in the arc-shaped can not produce lateral external forces to diaphragm 5 to the diffusion of product surrounding, prevents that diaphragm 5 is shifted.The utility model is simple in structure, practical.
The utility model also comprises some supplemental core 6, is used to form the suspension column on product, and supplemental core 6 one end are plugged on counterdie 3, and the other end is positioned at installation cavity.
Above-described embodiment is preferred version of the present utility model, and the utility model also can have other embodiments.Those skilled in the art also can make equivalent variations or replacement under the prerequisite without prejudice to the utility model spirit, and the modification that these are equal to or replace is all included in the scope that the application's claim sets.
