Abstract
The present invention relates to a kind of method improving injecting products generation bubble, described injecting products includes base, seal closure, described base and seal closure connect by being arranged on the rotating shaft of its side, it is provided with sealing block in the middle of described base, the method is to identical with the thickness of base by the enlarged in thickness of sealing block, by resin injection mo(u)lding in injection machine, the filling point of resin feeding is arranged at sealing block.Compared with prior art, the present invention has bubble-free, the advantage such as easily manufactured.
Description
Technical field
The present invention relates to the production of a kind of plastic product, especially relate to a kind of injecting products that improves and produce bubble
Method.
Background technology
Owing to plastic pellet adds thermal melting and is easily generated bubble, if when injection moulding during agitation in screw in injection molding machine
Resin is flowed at wall thickness by wall is thin, and the phenomenon of the not enough too fast cooling of resin flow velocity easily occurs in end, and part bubble is not
Can discharge in time i.e. solidifies in the product.Bubble easily shows in opaque products, affects appearance, and contains
The firmness of product of bubble own is the most poor, is easily ftractureed by external force.Can be improved this by changing raw material in the past
Problem, but change raw material and product colour is had certain impact, and a series of functional dimension and stable material quality need again
Test, expends the cycle longer.The present invention mainly makes improvements from product design structure, solves the generation of air bubble problem.
Summary of the invention
Defect that the purpose of the present invention is contemplated to overcome above-mentioned prior art to exist and a kind of highly reliable, system is provided
Make and improve the method that injecting products produces bubble easily.
The purpose of the present invention can be achieved through the following technical solutions: a kind of injecting products that improves produces the side of bubble
Method, described injecting products includes that base, seal closure, described base and seal closure are by being arranged on its side
Rotating shaft connects, and is provided with sealing block, it is characterised in that the method is to be added by the thickness of sealing block in the middle of described base
Big to identical with the thickness of base, by resin injection mo(u)lding in injection machine, the filling point of resin feeding is arranged on sealing
At block.
The shape of described sealing block and the mating shapes of seal closure.
It is provided with opening in the middle of described sealing block.
Described base, sealing block, seal closure thickness identical.
The generation of bubble is flowed at wall thickness mainly due to resin by wall is thin, and end occurs that resin flow velocity deficiency is too fast
The phenomenon of cooling, part bubble fails to discharge in time and solidifies in the product.The injecting products that improves of the present invention produces
The method of angry bubble, is to infuse resin into wall thickness increasing at point i.e. product filling point place to be allowed to flow to end with resin
Wall thickness is identical, to ensure that resin remains to keep certain temperature when injecting product end, is unlikely to too fast cooling, gas
Bubble can be discharged in time.
Compared with prior art, the invention have the advantages that
One, product air bubble problem is solved, it is ensured that product appearance is attractive in appearance and fastness function.
Two, maintain existing raw material, remove the size repeated needed for changing because of raw material, function and stability test from
Deng and consequent product discoloration problem.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment 1
As it is shown in figure 1, a kind of improve injecting products produce bubble method, described injecting products include base 1,
Seal closure 3, described base 1 and seal closure 3 connect by being arranged on the rotating shaft 4 of its side, described base
Being provided with sealing block 2 in the middle of 1, the method is to identical with the thickness of base 1 by the enlarged in thickness of sealing block 2, will
Resin is injection mo(u)lding in injection machine, and the filling point 5 of resin feeding is arranged at sealing block 2.
(sealing block is whole to the mating shapes of the shape of described sealing block 2 and seal closure 3, as close in figure
Shown in envelope block 2).It is provided with opening 6 in the middle of described sealing block 2.
Described base, the thickness of seal closure identical (base 1 is identical with the thickness of sealing block 2).
Original product wall thin place sealing block 2 is thickeied until with product wall thickness at i.e. base and seal closure thickness phase
With, therefore during injection mo(u)lding, resin is by filling a little 5 to go out to feed, sealing block 2 when flowing to base and seal closure, flow velocity is equal
Even, resin remains to keep certain temperature, is unlikely to too fast cooling, and bubble can be discharged in time, thus improves former
First it is being easily generated the bubble phenomenon that bubble face is occurred.
