Abstract

The present disclosure discloses a method for forming a silica gel diaphragm and a silica gel diaphragm prepared using the method. The method for forming a silica gel diaphragm includes at least the following steps: step S 1 : providing a hot pressing mold, and placing at least a dome as an embedment into the hot pressing mold; step S 2 : injecting liquid silica gel into the hot pressing mold; and step S 3 : molding the liquid silica gel via hot pressing so as to obtain a silica gel membrane which is at least connected with the dome. The method for forming a silica gel diaphragm provided by the present disclosure is easy to conduct and the formed silica gel diaphragm has good performance.

First claim

What is claimed is:

1. A method for forming a silica gel diaphragm, comprising following steps:
step S 1 : providing a hot pressing mould and a dome, and placing the dome as an embedment into the hot pressing mould;
step S 2 : providing liquid silica gel, and injecting the liquid silica gel into the hot pressing mould along an edge of the dome;
step S 3 : hot pressing the liquid silica gel so as to form a silica gel membrane which is connected with the dome, and then molding so as to form a silica gel membrane component; and
step S 4 : providing an injection machine, placing the silica gel membrane component as an embedment into the injection machine, forming a supporting frame for the silica gel membrane component via injection molding, the formed supporting frame being connected with an edge of an end of the silica gel membrane far away from the dome, and then molding so as to obtain the silica gel diaphragm.

2. The method for forming a silica gel diaphragm as described in claim 1 , wherein the step S 3 further comprises a step of cooling the molded silica gel membrane component.

3. A silica gel diaphragm prepared using the method for forming a silica gel diaphragm as described in claim 1 , comprising:
a silica gel membrane,
a dome, and
a supporting frame;
wherein the dome and the supporting frame are fixedly connected with the silica gel membrane, respectively; the silica gel membrane comprises a first connecting portion which is connected with the dome, a second connecting portion which is connected with the supporting frame, and a suspension portion which connects the first connecting portion with the second connecting portion.

4. The silica gel diaphragm as described in claim 3 , wherein the supporting frame comprises a ring-shaped frame body and a ring-shaped groove which is formed on an upper surface of the frame body, the second connecting portion comprises a body portion which is connected with the suspension portion, and a fixing portion which is bended and extends from an end of the body portion, the fixing portion is embedded into the ring-shaped groove.

5. The silica gel diaphragm as described in claim 4 , wherein the supporting frame further comprises a pressing block which is connected with the frame body and is configured to cover an upper surface of the fixing portion.

6. A silica gel diaphragm comprising:
a silica gel membrane,
a dome, and
a supporting frame;
wherein the dome and the supporting frame are fixedly connected with the silica gel membrane, respectively; the silica gel membrane comprises a first connecting portion which is connected with the dome, a second connecting portion which is connected with the supporting frame, and a suspension portion which connects the first connecting portion with the second connecting portion; the supporting frame comprises a ring-shaped frame body and a ring-shaped groove which is formed on an upper surface of the frame body; the second connecting portion comprises a body portion which is connected with the suspension portion, and a fixing portion which is bended and extends from an end of the body portion, the fixing portion is embedded into the ring-shaped groove; the supporting frame further comprises a pressing block which is connected with the frame body and is configured to cover an upper surface of the fixing portion.
