Description
Technical field
The utility model belongs to auto parts machinery production technical field, is related to a kind of auxiliary improvement injection mould of automobile chafing strip gas
Tool.
Background technology
At present in automobile chafing strip manufacturing technology field, body side molding, purpose can be all matched somebody with somebody on general coachbuilt body
It is to prevent slight collision and scratch from damaging certain protective effect to car paint, while plays certain decoration function.
Existing automobile chafing strip is made using high-strength engineering plastic injection, is sprayed into consistent face with vehicle body after injection
Color, makes car seem that associative perception is stronger, more have aesthetic feeling, and automobile chafing strip uses gas assisted molding here, and gas assisted molding refers to moulding
Glue be filled to cavity it is appropriate when (75%-99.9%) injection inertia high pressure nitrogen, gas push melting plastic cement continues to fill
Full cavity, a kind of injection molding technology of plastic cement pressure maintaining period is replaced with gas pressurize, auxiliary in the gas of injection chafing strip here
During due to product wall thickness can not normal injection molding, and be molded after in electroplating process the auxiliary Kong Zhongzang liquid of gas, cause product
Undesirable problem points.
The content of the invention
Technical problem to be solved in the utility model is the present situation for the prior art, and providing one kind can prevent from producing
Small stomata is formed during product gas assisted molding, lifts the auxiliary improvement injection mold of automobile chafing strip gas of the product yield of plating.
Technical solution is used by the utility model solves above-mentioned technical problem：A kind of automobile chafing strip gas is auxiliary to improve note
Mould, includes die ontology, and formed product platform is provided with the die ontology, is had on the formed product platform
Formed product chamber, for injection molding machine to shaping intracavitary administration injection molding material, injection molding material flowing filling under the control of forming cavity intrinsic pressure is whole
A cavity, it is characterised in that the formed product chamber includes the convex face of concave face and both sides, concave face position
Between two convex faces, external drainage groove is provided with the convex face, the direction that opens up of the external drainage groove is convex
The extending direction in type face, the depth of the drainage trough is 3-5mm.
The measure taken for optimization such scheme specifically includes：
In a kind of above-mentioned auxiliary improvement injection mold of automobile chafing strip gas, also it is spaced apart on the concave face and is equipped with interior draw
Chute.
In a kind of above-mentioned auxiliary improvement injection mold of automobile chafing strip gas, the formed product chamber wherein side convex
Two external drainage grooves are provided with face, offer water conservancy diversion lead-out groove between two external drainage grooves, the water conservancy diversion draws
Go out groove from horizontal direction with external drainage groove through connection.
Compared with prior art, the utility model has the advantage of drawn by external drainage groove, interior drainage trough and water conservancy diversion
Groove can prevent from forming small stomata when products gas-assist is molded, and only need to subsequently increase the action for manually cutting flash after extraction, i.e.,
It can ensure the integral molded plastic Forming Quality of whole automobile chafing strip, improve the product yield of follow-up plating, reduction is produced into
This.
Brief description of the drawings
Fig. 1 is the auxiliary dimensional structure diagram for improving injection mold of this automobile chafing strip gas；
Fig. 2 is the other direction structure diagram of Fig. 1.
Embodiment
It is specific embodiment of the utility model and with reference to attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these embodiments.
In figure, die ontology 1；Formed product platform 2；Formed product chamber 3；Concave face 4；Convex face 5；External drainage groove 6；Inside draw
Chute 7；Water conservancy diversion lead-out groove 8.
As depicted in figs. 1 and 2, the auxiliary injection mold that improves of this automobile chafing strip gas is primarily used to injection molded automobile chafing strip
, due to the product wall thickness of this injection molded automobile chafing strip, it can not meet product requirement by normal injection and mould process, including
There is die ontology 1, can once be molded two products in the present embodiment here, formed product platform 2 is provided with die ontology 1,
There is formed product chamber 3, formed product chamber 3 is mutually fitted with actual automobile chafing strip shape of product here on formed product platform 2
Should, for injection molding machine to shaping intracavitary administration injection molding material, whole cavity, production are filled in injection molding material flowing under the control of forming cavity intrinsic pressure
Product forming cavity 3 includes the convex face 5 of concave face 4 and both sides, concave face 4 between two convex faces 5, convex face
External drainage groove 6 is provided with 5, external drainage groove 6 opens up the extending direction that direction is convex face 5, and the depth of drainage trough is 3-
5mm, opens up the extending direction that direction is convex face 5 due to external drainage groove 6, so that is causes during gas is auxiliary
Unnecessary whole injection molding material can be drawn along external drainage groove 6 from the forming direction of product, so that when ensureing products gas-assist
Quality on convex face 5, is also spaced apart on concave face 4 and is equipped with interior drainage trough 7, it is same here in drainage trough 7 and along concave
The extending direction in face 4, so that unnecessary whole injection molding material can be along interior 7 groove of drainage trough from product during such gas is auxiliary
Forming direction on draw, so as to ensure the Forming Quality on concave face 4, formed product chamber 3 is wherein set on side convex face 5
There are two external drainage grooves 6, water conservancy diversion lead-out groove 8 is offered between two external drainage grooves 6, water conservancy diversion lead-out groove 8 is from horizontal direction
With 6 through connection of external drainage groove, here injection molding material unnecessary during actual gas is auxiliary can overstock on outer drainage trough 6, this
In set the water conservancy diversion lead-out groove 8 to be the efficiency for further improving extraction so that quality when ensureing products gas-assist.
The specific embodiments described herein are merely examples of the spirit of the present invention.The utility model institute
Described specific embodiment can be done various modifications or additions or using similar by belonging to those skilled in the art
Mode substitute, but defined scope without departing from the spirit of the present application.
