Abstract
Automobile rear bumper mould fan gate, including mold cores, two of core arranges corner insert, slanted kicking block is set under corner insert, core, corner insert and slanted kicking block arrange the die cavity of automobile rear bumper, injection mo(u)lding automobile rear humper in die cavity, described core two respectively arranges a zanjon runner, zanjon runner is connected above expecting mouth, and zanjon runner extends forward, connects with the die cavity of automobile rear humper in fan shape cast gate from the bottom up.During injection, melted plastic raw materials enters from material mouth, is injected in zanjon runner, then by fan shape cast gate, it is injected in the die cavity of automobile rear bumper, owing to fan shape cast gate is sector structure, the maximum outer rim of cast gate is in exit, it is possible to form quick feeding (entering glue), die cavity is made to could quickly fill up, do not condense, without koro, improve product quality.And the height of fan gate is little, the widest but also thin at whole gate outlet, easily break, it is simple to product ejection device.
Description
Technical field
This utility model relates to a kind of automobile rear bumper mould fan gate, belongs to injection mold field.
Background technology
Injection mold is used to produce the rear bumper of plastic, such as automobile.Watering of orthodox car rear bumper arm mould
Mouth is general uses submarine or multi-point sprue.Sub marine gate is typically Cornu Bovis seu Bubali shape, and cast gate is descending, due to rear bumper
Volume is big, sub marine gate to enter the glue time long, easily cause, raw material condenses, and fills insufficient, affects product quality；And it is many
Spot pouring mouth has the drawback that cast gate quantity is many, and when the demoulding, the coating pulling force in cast gate is big, affects product and ejects.
Summary of the invention
The purpose of this utility model is the shortcoming in order to overcome prior art, it is provided that a kind of employing fan shape cast gate, cast gate
Face width, thin, both entered glue speed fast, the most easily broken, it is simple to the automobile rear bumper mould fan gate of the demoulding.
The technical scheme of this utility model automobile rear bumper mould fan gate is: include mold cores, the two of core
Head arranges corner insert, arranges slanted kicking block, core, corner insert and slanted kicking block arrange automobile rear bumper under corner insert
Die cavity, injection mo(u)lding automobile rear humper in die cavity, it is characterised in that described core two respectively arranges a zanjon runner, deeply
Ditch runner is connected above expecting mouth, and zanjon runner extends forward, from the bottom up in the die cavity of fan shape cast gate Yu automobile rear humper
Connection.
Automobile rear bumper mould fan gate of the present utility model, is mainly characterized by arranging zanjon on described core
Runner, zanjon runner extends forward, and the die cavity connection in fan shape cast gate automobile rear humper, during injection, melted from the bottom up
Plastic raw materials enter from material mouth, be injected in zanjon runner, then by fan shape cast gate, be injected into automobile rear bumper
In die cavity, owing to fan shape cast gate is sector structure, the maximum outer rim of cast gate is in exit, it is possible to forms quick feeding and (enters
Glue), make die cavity could quickly fill up, do not condense, without koro, improve product quality.And the height of fan gate is little, whole gate outlet
Locate the widest but also thin, easily break, it is simple to product ejection device.
Automobile rear bumper mould fan gate of the present utility model, the Breadth Maximum W1 of described fan shape cast gate is wide
Degree is 15.9mm for 19.8mm, minimum widith W2, and the exit height H of fan shape cast gate is >=0.83mm, fan shape cast gate
Exit is the widest, and flow velocity is fast, enters glue speed fast, and melted plastic raw materials can could quickly fill up die cavity, and the clout height stayed is very
Thin, easily break, it is simple to product ejects.Arranging nest shape interface on described zanjon runner, nest shape interface matches with material mouth, joins
Close closely.

Detailed description of the invention
This utility model relates to a kind of automobile rear bumper mould fan gate, as shown in Fig. 1 Fig. 4, including mould type
Core 1, two of core arranges corner insert 2, arranges slanted kicking block 3, on core 1, corner insert 2 and slanted kicking block 3 under corner insert
Arranging the die cavity of automobile rear bumper, injection mo(u)lding automobile rear humper 4 in die cavity, described core 1 two respectively arranges one
Zanjon runner 5, zanjon runner 5 is connected above expecting mouth 6, and zanjon runner 5 extends forward, from the bottom up in fan shape cast gate 7 and vapour
The die cavity connection of car rear bumper arm 4.This programme be mainly characterized by arranging zanjon runner 5, zanjon runner on described core 1
5 extend forward, from the bottom up the die cavity connection in fan shape cast gate 7 automobile rear humper 4, during injection, and melted plastic raw materials
Enter from material mouth 6, be injected in zanjon runner 5, then by fan shape cast gate 7, be injected into the die cavity of automobile rear bumper 4
In, owing to fan shape cast gate 7 is in sector structure, the maximum outer rim of cast gate is in exit, it is possible to forms quick feeding (entering glue), makes
Die cavity could quickly fill up, and does not condenses, and without koro, improves product quality.And the height of fan gate is little, the widest at whole gate outlet
The thinnest, easily break, it is simple to product ejection device.The Breadth Maximum W1 of described fan shape cast gate 7 be width be 19.8mm,
Little width W2 is 15.9mm, and the exit height H of fan shape cast gate 7 is >=0.83mm, and the exit of fan shape cast gate is the widest, stream
Speed is fast, enters glue speed fast, and melted plastic raw materials can could quickly fill up die cavity, and the clout height stayed is the thinnest, easily breaks, just
Eject in product.Arranging nest shape interface 8 on described zanjon runner 5, nest shape interface 8 matches with material mouth 6, coordinates closely.
