Description
Technical field
The present invention relates to a kind of flexible switch injection molding process.
Background technique
With making rapid progress for electrical application technology, consumer also promotes Product Interface and quality requirement constantly.
The fashion of product appearance, the sensitivity of function all become the chip of competition among enterprises.Capacitance switch is as a kind of new touch switch
System meets requirements above, while also improving service life and the durability of key, but production cost is relatively high.
Summary of the invention
The purpose of the present invention is to provide a kind of flexible switch injection molding process.
The technical solution adopted by the present invention is that：
A kind of flexible switch injection molding process, includes the following steps：Step 1：The PET film piece printed is placed into knife
It is punched out in mould, sheet material both ends location hole is placed on the cutting die location hole that diameter is 2 mm when punching and is punched out；
Step 2：Baked material rice is placed in storage vat, Flue curing parameter when material rice toasts is 80 DEG C, 2H；
Step 3：Injection molding machine parameter is set, and before the PET panel diaphragm being punched is placed into mould die cavity, sheet material is just
Face is contacted with preceding mould die cavity；
Step 4：ITO film diaphragm and PET film piece are integrated by being molded, complete production.
In the step 4, row's needle is put into mold rear mold die cavity, mold-closing injection production is finally carried out, after being molded it
The one of contact pin comes in material rice, and another row of contact pin is just pressed on carbon slurry of the tail with route, so that line signal inputs
End is inputted from contact pin position, completes production.
In the step 4, the film diaphragm front ITO that will be punched is contacted with rear die cavity, by the location hole on diaphragm
Be inserted in rear mold pilot pin, with guarantee its attach completely in rear mold, by ITO film tail band to after being inserted into after the 90-degree bent of front
In die cavity, then by insert reeve die cavity, to be completely fixed position of the tail band in rear mold, last mold-closing injection completes production.
In the step 4, preceding mould die cavity and rear die cavity are molded, semi-finished product is molded into, the semi-finished product of injection formed is put into
It is positive to be contacted with preceding mould die cavity in the preceding mould die cavity of another injection mould, by ITO film diaphragm be placed in the half of injection formed at
The product back side preceding mould die cavity and rear die cavity mold-closing injection are completed into production.
Advantages of the present invention：In the working environment of IMD product, realizes capacitive sensing function, expand the scope of application of product；
It is bonded without glue system, realizes integrated molding；Product is both artistic and practical, and inductive effects are excellent.

Specific embodiment
As shown in Figs 1-4, a kind of flexible switch injection molding process, includes the following steps：Step 1：By what is printed
PET film piece is placed to be punched out in cutting die, and sheet material both ends location hole is placed in the cutting die location hole that diameter is 2 mm when punching
On be punched out；
Step 2：Baked material rice is placed in storage vat, Flue curing parameter when material rice toasts is 80 DEG C, 2H；
Step 3：Injection molding machine parameter is set, and before the PET panel diaphragm being punched is placed into mould die cavity, sheet material is just
Face is contacted with preceding mould die cavity；
Step 4：ITO film diaphragm and PET film piece are integrated by being molded, complete production.
In the step 4, row's needle is put into mold rear mold die cavity, mold-closing injection production is finally carried out, after being molded it
The one of contact pin comes in material rice, and another row of contact pin is just pressed on carbon slurry of the tail with route, so that line signal inputs
End is inputted from contact pin position, completes production.
In the step 4, the film diaphragm front ITO that will be punched is contacted with rear die cavity, by the location hole on diaphragm
Be inserted in rear mold pilot pin, with guarantee its attach completely in rear mold, by ITO film tail band to after being inserted into after the 90-degree bent of front
In die cavity, then by insert reeve die cavity, to be completely fixed position of the tail band in rear mold, last mold-closing injection completes production.
In the step 4, preceding mould die cavity and rear die cavity are molded, semi-finished product is molded into, the semi-finished product of injection formed is put into
It is positive to be contacted with preceding mould die cavity in the preceding mould die cavity of another injection mould, by ITO film diaphragm be placed in the half of injection formed at
The product back side preceding mould die cavity and rear die cavity mold-closing injection are completed into production.
In the working environment of IMD product of the present invention, realizes capacitive sensing function, expand the scope of application of product；Without glue
System's fitting, realizes integrated molding；Product is both artistic and practical, and inductive effects are excellent.
