Description
Technical field
The present invention relates to pouring gate structure technical field, more particularly to a kind of gate nub for being used to overcome product gas trace defect
Structure.
Background technology
In automobile industry, decorative appearance plastic product generally has very high quality requirements, in process of production, some products
In addition to snapped-in position, remaining all appearance, and outward appearance has plating to require, now shadow of the gas trace defect to product quality
Sound is particularly acute, and in order to solve this problem, workman generally selects into glue position and product wall thickness and increase cast gate wall thickness is thinned, connects
Both modes of nearly product wall thickness are handled, but both modes have the limitation of oneself, and product wall thickness is thinned first
This scheme easily causes product and is difficult time processing in place；Injection pressure increases, and overlap easily occurs；Product end easily occurs
Shrink, and increase cast gate wall thickness and be likely to result in gate thickness increase, difficulty is wiped out；Product is difficult cooling, and production cycle extension is
Solve the above problems, design a kind of special pouring gate structure and be necessary.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of pouring gate structure for being used to overcome product gas trace defect, have
Can be effectively prevented from the gas trace generation of product, cast gate wipe out residual do not influence presentation quality and assembling, the reduction production cycle from
And improve production efficiency, while the features such as further improving the qualification rate of product.
The technical solution adopted for the present invention to solve the technical problems is：There is provided a kind of for overcoming product gas trace defect
Erected on pouring gate structure, including ox horn sub-marine gate, dozzle and main cast gate, the ox horn end of described ox horn sub-marine gate
Straight to be disposed with dozzle, the upper end of dozzle is disposed with the main cast gate bent towards ox horn sub-marine gate direction, described
Main cast gate bends and connected with the cavity of injection mold upward close to one end of ox horn sub-marine gate, and described main cast gate is close to ox
Ladder bending structure is used at the bending end of angle sub-marine gate.
Described dozzle upper end is tilted with main cast gate opposite side towards main cast gate direction.
Coolant flow channel is disposed with above the bulk end of described ox horn sub-marine gate.
Utilize the forming step of Moldflow software analog equipment gas trace defects.First, melt is flowed through by flow passage system and poured
Stenostomia space enters after die cavity, sets up first time pressure balance；Under first time pressure-balanced condition, melt starts contact
Die wall；Due to reasons such as melt radiatings, melt forward starts to remain in a standstill and slowed down, and now the secondary pressure of gate area starts to build
It is vertical；During secondary pressure is rebalanced, melt forward Yi Fasheng is stagnated, cooling, play, crimping, trapped gas, or even is returned
The phenomenons such as stream cause gas trace.
And in actual production process, gate area melt enters the short of glue behavior and penetrates experiment, melt has just entered die cavity, occurs
Pressure balance, after melt forward reaches die surface, secondary pressure is begun setting up, and crimping occurs in forward's melt, is stranded
The behaviors such as gas.Secondary pressure continues to increase, and the melt for taking the lead in having cooled down into die cavity is melted again, stretches, in cast gate
Region forms obvious gas trace.
In order to avoid the generation of gas trace, the runner cast gate of this technology is devised, melt is by gate area directly in product
Balance pressure field is formed on die wall, the foundation of secondary pressure is eliminated, largely avoids the formation of gas trace.
Beneficial effect：It is used to overcome the pouring gate structure of product gas trace defect the present invention relates to a kind of, with can be effectively
The gas trace of product is avoided to generate, cast gate wipes out residual does not influence presentation quality and assembling, reduction production cycle so as to improving product
Production efficiency, while further improve product qualification rate the features such as.

Embodiment
With reference to specific embodiment, the present invention is expanded on further.It should be understood that these embodiments are merely to illustrate the present invention
Rather than limitation the scope of the present invention.In addition, it is to be understood that after the content of the invention lectured has been read, people in the art
Member can make various changes or modifications to the present invention, and these equivalent form of values equally fall within the application appended claims and limited
Scope.
Embodiments of the present invention are related to a kind of pouring gate structure for being used to overcome product gas trace defect, as shown in Fig. 1-2,
Including ox horn sub-marine gate 1, dozzle 2 and main cast gate 3, vertical cloth on the ox horn end of described ox horn sub-marine gate 1
Dozzle 2 is equipped with, the upper end of dozzle 2 is disposed with the main cast gate 3 bent towards the direction of ox horn sub-marine gate 1, described
Main cast gate 3 is bent upward close to one end of ox horn sub-marine gate 1 to be connected with the cavity of injection mold, and described main cast gate 3 is leaned on
Ladder bending structure 5 is used at the bending end of nearly ox horn sub-marine gate 1.
The described upper end of dozzle 2 is tilted with the main opposite side of cast gate 3 towards the main direction of cast gate 3.
Coolant flow channel 4 is disposed with above the bulk end of described ox horn sub-marine gate 1.
Embodiment
Ox horn sub-marine gate 1 is designed in sprue mold insert, and the top of ox horn sub-marine gate 1 is disposed with coolant flow channel 4, melts
Liquid enters from ox horn sub-marine gate 1 flows to dozzle 2, and is moved by dozzle 2 towards the direction of main cast gate 3, moves
During dynamic, the die wall (i.e. ladder bending structure 5) first in front is collided, in the follow-up multiple-contact die wall of process (i.e. rank
Terraced bending structure 5) after, fountain flow is formed again, continues to fill die cavity, generally arranges that product is carried on the back when this pouring gate structure is used
Face, when the structure largely avoided production because the generation of secondary pressure and caused by gas trace appearance, so as to improve production
The quality of product.
