During the forming process of the triangular window with an embedded glass insert, an injection mold is needed for insert molding, and the glass needs to be placed and positioned in the mold cavity. In the existing technology, due to the limitation of the product structure, the space between the glass positioning edge and the mold is very small (usually only 3 mm). If the conventional piston-type cylinder is used to drive the positioning rod, the positioning rod will interfere with the mold structure and cannot achieve the effect of glass positioning, resulting in the failure of the entire project. Therefore, it is necessary to accurately position the glass in the injection mold for the injection-molded glass under the condition of limited space to facilitate the implementation of the injection molding process. Summary of the Utility Model

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] As Figures 1-4 shown, in order to solve the problem of glass positioning under limited space in the molding of existing triangular window glass inserts, the present invention provides the following technical solutions: a glass positioning structure for an injection mold for molding automotive triangular window inserts, including: at least one glass positioning unit, which is arranged at a position close to the mold cavity between the lower template 16 and the upper template 15 of the injection mold. The glass positioning unit includes a rotating element 1 and a fixing block 2 installed on the transverse main shaft of the rotating element 1. The first end of the fixing block 2 is connected to the transverse main shaft, and at least one positioning rod 4 is installed at the second end of the fixing block 2. The rotating element 1 drives the positioning rod 4 to flip into the edge of the glass placement position in the mold cavity through the fixing block 2, or drives the positioning rod 4 to flip outside the mold cavity to a range where it is separated from the mold cavity. By setting the rotating element 1, the flipping of the positioning rod 4 can be realized, and the flipping movement of the positioning rod 4 will not interfere with the molding of the triangular window insert, thus solving the problem of glass positioning under limited space in the molding of existing triangular window glass inserts.

[0021] Specifically, a hollow space can be formed between the lower template 16 and the upper template 15 of the existing injection mold for placing the glass positioning unit, and the glass positioning unit only works when the mold is opened. The number of glass positioning units can be flexibly matched according to the size and shape of the glass. Correspondingly, the number and position of the positioning rods 4 on each rotating element 1 can also be set according to the actual size of the glass. When the positioning rods 4 flip to the corresponding edge of the glass placement position, the glass can be manually placed and leaned against the multiple positioning rods 4 to achieve positioning. Among them, a bending part 9 extending downward is arranged at the free end of the positioning rod 4, and the glass can be horizontally limited through the bending part 9 to avoid the position of the triangular window glass insert molding. The shape of the position of the positioning rod 4 other than the bending part 9 can be adjusted as needed, and it can be curved or straight.

[0022] In this embodiment, insertion slots 5 for installing and fixing the positioning rod 4 are arranged on the upper side and side of the second end of the fixing block 2, which is convenient for flexibly installing and fixing the positioning rod 4. One end of the positioning rod 4 is embedded or inserted into the insertion slot 5, and then fixed by screws, and the installation of the positioning rod 4 can be realized. Different positioning rods 4 can be installed on one fixing block 2 through the insertion slots 5 at different positions to meet diverse positioning requirements.

[0023] In order to limit the rotation angle of the fixed block 2, a limit post 6 is installed on the lower side of the second end of the fixed block 2, which can limit the rotation angle of the transverse main shaft of the rotating element 1. When the limit post 6 abuts against the limit step on the lower template 16, the fixed block 2 cannot rotate, so that the positioning rod 4 will not hit the mold and damage the mold. Among them, the limit post 6 can be set as a detachable structure, which is convenient for replacement according to needs and adjustment of different flipping angles.

[0024] In this embodiment, as an implementation manner of the rotating element 1, the rotating element 1 is a rotating cylinder. The air inlet and air outlet of the rotating cylinder are connected to a manual air valve 8 through an air pipe 7, and the control is simple and convenient, and can be operated manually. The manual air valve 8 can be installed outside the mold or on the outer wall of the mold, which is convenient for manual operation.

[0025] Among them, as Figure 2 shown, the bottom of the rotating element 1 is installed on the lower template 16 through a fixed base 3. The fixed base 3 can stably install the rotating element 1 on the lower template 16 and will not displace during use.

[0026] As Figures 3-4 shown, as an installation and use manner of the glass positioning unit, the glass positioning unit includes a first glass positioning unit 11 and a second glass positioning unit 10 arranged side by side on the side of the mold cavity. Among them, the second glass positioning unit 10 is installed at a position close to the glass corner. A first positioning rod 12 is installed on the fixed block 2 of the first glass positioning unit 11, and a second positioning rod 13 and a third positioning rod 14 are installed on the fixed block 2 of the second glass positioning unit 10. The free ends of the second positioning rod 13 and the third positioning rod 14 respectively extend to both sides of the glass corner. By setting two glass positioning units and three positioning rods, rapid and accurate positioning of the glass can be achieved.

[0027] In this embodiment, a rotating cylinder is used as the rotating element 1 in the glass positioning unit. The steps of injection molding of the triangular window glass insert are as follows: First is the positioning stage. In the mold opening state, the mold cavity opens, the lower template 16 is separated from the upper template 15, and the manual air valve 8 is manually opened. All the rotating elements 1 drive the fixed block 2 to rotate, rotating 165° to flip the positioning rod 4 to the glass limiting position; then is the glass placing stage, and the glass is placed manually relying on all the positioning rods 4; then is the positioning rod reset stage, the manual air valve 8 is closed, and the rotating element 1 drives the fixed block 2 to reverse flip, so that all the positioning rods 4 return to the original position and will not affect mold closing. Finally is the injection molding, pressure holding, mold opening, and ejection stage. At this time, a complete mold action is completed.
