Glass encapsulation structure and injection molding device

1. A glass encapsulation structure, comprising:

a guide piece; and

an encapsulation component,

wherein the guide piece is fixed to a side surface of a glass through the encapsulation component,

wherein the guide piece comprises a strip part, a plurality of bumps and at least one positioning hole, and

wherein the strip part has a first surface, and a second surface which is opposite to the first surface and faces an interior of a vehicle body when the guide piece is mounted onto the vehicle body, the plurality of bumps are located on the first surface and perpendicular to the first surface, the at least one positioning hole is formed in at least one of the bumps, an axis of the at least one positioning hole is perpendicular to the side surface of the glass, and the at least one positioning hole is adapted for matching at least one positioning pin in an injection molding device in an injection molding process, such that a position relationship between the guide piece and the glass retains unchanged in the injection molding process.

2. The glass encapsulation structure according to claim 1 , wherein the guide piece further comprises a sealing part perpendicular to the first surface of the strip part, wherein the sealing part is adjacent to the side surface of the glass, and extends flush with or beyond a surface of the glass.

3. The glass encapsulation structure according to claim 2 , wherein the encapsulation component covers the side surface of the glass, the sealing part, and the second surface of the strip part.

4. The glass encapsulation structure according to claim 1 , wherein the plurality of bumps are adapted for mounting the guide piece onto the vehicle body.

5. The glass encapsulation structure according to claim 1 , wherein the at least one positioning hole comprises one positioning hole disposed in one bump in the middle of the strip part, or the at least one positioning hole comprises a plurality of positioning holes disposed in the plurality of bumps, respectively.

6. The glass encapsulation structure according to claim 1 , wherein the at least one positioning hole is circular, and each positioning pin comprises:

a first terminal adapted for being inserted into one positioning hole during an injection molding process; and

a second terminal adapted for being fixed in an injection molding mould,

wherein the positioning pin has a shape of cone whose size increases gradually from the first terminal to the second terminal, the first terminal has a size smaller than a size of the positioning hole, and the second terminal has a size greater than the size of the positioning hole, and

wherein after the at least one positioning pin is inserted into the at least one positioning hole, an interference fit is formed therebetween.

7. The glass encapsulation structure according to claim 1 , wherein the at least one positioning hole is square, and each positioning pin comprises:

a first terminal adapted for being inserted into one positioning hole during an injection molding process; and

a second terminal adapted for being fixed in an injection molding mould,

wherein the positioning pin has a shape of wedge whose size increases gradually from the first terminal to the second terminal, the first terminal has a size smaller than a size of the positioning hole, and the second terminal has a size greater than the size of the positioning hole, and

wherein after the at least one positioning pin is inserted into the at least one positioning hole, an interference fit is formed therebetween.

8. The glass encapsulation structure according to claim 1 , wherein each positioning pin comprises:

a first terminal which has a step and is adapted for being inserted into one positioning hole during an injection molding process; and

a second terminal adapted for being fixed in an injection molding mould,

wherein after the first terminal is inserted into the positioning hole, the step presses against an edge of the positioning hole.
