Abstract
The utility model discloses a novel mold injection structure, comprising a hot glue passage system and a mold cavity. The hot glue passage is embedded in the mold cavity, which comprises a glue passage portal body and a valve needle in flexible connection with the glue passage portal body and matching with the finished product by the mold cavity. In addition, a heat insulation pad is arranged between the glue passage portal body and the cavity. The glue passage portal body, the heat insulation pad and the cavity closely contact with each other in sequence. In the utility model the heat insulation pad fills the clearance between the glue passage portal body and the cavity, which can provide the glue passage portal body with a space for expansion by heating to avoid the heat loss of the glue passage portal body. And with the removed clearance, wide waves can be effectively avoided on the mold product.
Description
Technical field
The utility model relates to a kind of cast structure, particularly a kind of novel die cast structure.
Background technology
In the moulding by casting of mould product, adopt the hot glue road of needle valve directly to advance glue on finished product, do not leave the gap because of hot glue road body contacts fully with the mould die, and along with the continuous motion of needle, defective material can be left in the gap herein, after heating after a while, this defective material begins the nitrogenize flavescence, and when follow-up injection finished product, this defective material can be dashed as for finished surface, cause near product position glue-feeder yellow line to occur, cause product appearance bad and scrap.
Because during hot glue road cast glue, the hot glue channel temp raises and produces certain expansion, therefore must need to be provided with certain clearance between this hot glue road system and this mould die, in addition, if hot glue road system closely contacts on this mould die, then Zhu She glue can conduct to this mould die via hot glue road system with heat, thereby causes heat-energy losses.Therefore, must be provided with certain clearance between hot glue road system and the mould die, and the existence in this gap certainly will cause product bad order to occur.
Summary of the invention
In view of the above problems, the purpose of this utility model is to provide a kind of novel die cast structure, it has eliminated the gap between above-mentioned hot glue road system and the mould die, thereby has avoided leaving defective material owing to the existence in this gap, thereby has avoided mould product the phenomenon of yellow line to occur.
For reaching above-mentioned purpose, the utility model has adopted following technical scheme: a kind of novel die cast structure, comprise hot glue road system and mould die, this hot glue road system is embedded in this die, this hot glue road system comprises the needle of glue road junction body and flexible connection thereof, and this needle cooperates this mould die shaped article, it is characterized in that, be provided with heat insulating mattress between this glue road junction body and the die, this glue road junction body, heat insulating mattress, die are closely conflicted successively.
Preferable, this heat insulating mattress is an elasticity heat insulating mattress.
Than prior art, the utility model utilizes heat insulating mattress to eliminate gap between this glue road junction body and the die, this heat insulating mattress can provide the space of this glue road junction body expanded by heating and avoid this glue road junction heat-energy losses, in addition, the elimination in this gap more can effectively avoid mould product the phenomenon of yellow line to occur.
Description of drawings
Fig. 1 is the schematic cross-section of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figure 1, the novel die cast structure of the utility model comprises hot glue road system 100 and mould die 200, this hot glue road system 100 comprises glue road junction body 110 and needle 120, this needle 120 is movably connected on this glue road junction body 110, this hot glue road system 100 is embedded in this die 200, and this needle 120 cooperates this this product 300 of die 200 moulding, in addition, also be provided with an elasticity heat insulating mattress 111 between this glue road junction body 110 and the die 200, this glue road junction body 110, heat insulating mattress 111 and die 200 are closely conflicted successively.
So, during this die casting structure cast product 300, these glue road junction body 110 expanded by heating, certain elastic deformation takes place so that this space that glue road junction body 110 expands to be provided in this heat insulating mattress 111, and this heat insulating mattress 111 can be avoided the heat of this glue road junction body 110 to conduct on this die 200 and cause heat-energy losses, in addition, and the elimination in this gap, can avoid on this gap, staying defective material, thereby can avoid on product 300 occurring the phenomenon of yellow line.
Claims (2)
1. a novel die is poured into a mould structure, comprise hot glue road system and mould die, this hot glue road system is embedded in this die, this hot glue road system comprises the needle of glue road junction body and flexible connection thereof, this needle cooperates this mould die shaped article, it is characterized in that, be provided with heat insulating mattress between this glue road junction body and the die, this glue road junction body, heat insulating mattress, die are closely conflicted successively.
2. novel die cast structure according to claim 1 is characterized in that this heat insulating mattress is an elasticity heat insulating mattress.
