Road.
By using above-mentioned technical proposal, type chamber is formed between upper die and lower die, type chamber includes being set in upper mold
Upper impression and the lower impressions being set in lower die are equipped with several injecting holes in upper impression and lower impressions, and each injecting hole wraps
The exit orifice for including injection molding channel and being coated on outside injection molding channel, exit orifice are connected with outer flow passage, are arranged using the above structure, runner letter
Single, stability is strong, bolster will be further equipped between injection molding channel and exit orifice, and the bolster is set as including connecting
The breeze way for connecing section and connecting with linkage section, linkage section is sheathed on outside injection molding channel, and is interference fitted with injection molding channel, is made
Connective stability between bolster and injection molding channel, further set the end face of breeze way is concordant with the hole end surface of exit orifice
It sets, enables the flowing that mould-injection is stable, and be evenly equipped with several interior runners on the inner wall of breeze way, pass through setting
Interior runner forms current difference when ensuring that mould-injection flowing, and then ensure that anti-so that mould-injection is able to carry out shunting
The phenomenon that only forming bubble.
The utility model is further arranged to: the interior runner include the inner end being connect with linkage section and along injection molding liquid
The width of the elongated end of flow direction setting, interior runner is gradually increased from inner end toward extreme direction is extended.
By using above-mentioned technical proposal, interior runner includes the inner end connecting with linkage section and moves side along injection molding liquid stream
To the elongated end of setting, the width of interior runner is gradually increased from inner end toward extreme direction is extended, and is arranged using the above structure, gradually
The width of runner in increasing, it is ensured that mould-injection forms current difference in flowing, and then ensure that and prevent from being formed showing for bubble
As.
The utility model is further arranged to: the internal diameter of the breeze way is gradually increased along injection molding liquid flow direction.
By using above-mentioned technical proposal, the internal diameter of breeze way is gradually increased along injection molding liquid flow direction, using above-mentioned knot
Structure setting provides the effect of a buffering for injection molding liquid, and then it is good steady to ensure that injection molding liquid is formed when full of injecting hole
Effect is determined, to guarantee good injection molding effect.
