A kind of side gate hot flow path provided by the utility model, including hot mouth ontology and hot mouth head, it is longitudinal in hot mouth ontology
Equipped with perforative sprue, sprue upper end is initial glue-feeder, and sprue lower end side is equipped with multiple inclined runners, often
The exit of a runner, which cooperates, is equipped with hot mouth head；When injection molding, molten plastic enters from the initial glue-feeder of hot mouth ontology, warp
Sprue flows down, then in the mode respectively through runner and hot mouth head injection mold.This side gate is molded directly within mode
On hot flow path, it is excellent to have that cast gate is hidden, gate vestiges are small, stress is small, molding cycle greatly shortens, processing and installation facilitates etc.
Point.
Further, runner is made of first runner and second flow channel, under the first end and sprue of first runner
End connection, the second end of first runner are connected to the first end of second flow channel, and the second end of second flow channel is connected to hot mouth head, the
One runner and second flow channel are oblique runner, and first runner tilt angle is greater than second flow channel, to form inclined shunting
Road.The setting of this runner structure can make flowing velocity of the molten plastic in runner both will not be too fast, will not be too
Slowly.
Further, the quantity of runner is four.But not limited to this, it is also possible to one, two or three etc.,
This is no longer described in detail.
Further, runner is evenly distributed on hot mouth body peripheral.
It further, further include a hot mouth flange and a hot mouth external member, hot mouth flange and hot mouth external member are socketed in hot mouth
On body outer wall, and hot mouth flange with respect to hot mouth external member closer to initial glue-feeder, hot mouth head is arranged in the hot mouth external member.
Further, hot mouth external member both ends are respectively to be inserted in end and tail end, and tail end offers smaller than being inserted in stomidium diameter
Mounting hole；Hot mouth ontology lower end is the body structure being nested with mounting hole, and runner is arranged on body structure side wall；
Hot mouth head has the hot mouth head entrance that cooperation is connect with runner, and hot mouth head entrance is provided in inner wall of the hole installing.
The utility model uses technical solution as above, has the following beneficial effects:
It is equipped with sprue in the hot mouth ontology of the utility model, one to four runner can be set by side mouth,
Side gate is molded directly in mold cavity, when injection molding, by injection pressure plastics squeezing type chamber, after die sinking, passes through die sinking
The shearing force of power cuts off plastics, can obtain beautiful hidden side gate appearance, also has cast gate stress small and molding cycle
The advantages of greatly shortening；The utility model can realize integrated design, so that number of components tails off, be easily installed and tie up
Shield.
