Description

Technical Field

[0001] This utility model relates to the technical field of forming automotive windshields, and more particularly to a glass pressing mold. Background Technology

[0002] In the production process of glass products, glass pressing molds play a crucial role.

[0003] Traditional glass pressing molds have a design that limits the number of pieces of glass that can be pressed at once. This piece-by-piece pressing method significantly impacts production efficiency and results in poor conformation of the pressed glass. Under large-scale production demands, the frequent repetition of loading, pressing, and unloading operations not only increases labor costs but also consumes a significant amount of time, leading to a prolonged overall production cycle. Utility Model Content

[0004] The purpose of this invention is to provide a glass pressing mold to solve the above-mentioned technical problems.

[0005] The technical solution adopted in this utility model is as follows: A glass pressing mold includes a lower mold and a hot bending mold that cooperates with the lower mold. The hot bending mold includes an upper mold, a lifting mechanism, an upper mold positioning mechanism, a lower mold positioning mechanism, and an upper mold mounting frame. The upper mold is mounted inside the mounting frame and above the lifting mechanism. The lower mold positioning mechanism is mounted at both ends of the upper mold mounting frame. The upper mold positioning mechanism is mounted on the upper mold mounting frame and the lifting mechanism.

[0006] Preferably, the lifting mechanism includes a linear electric cylinder, a bottom frame, and a positioning frame. The bottom frame is located at the upper end of the linear electric cylinder, and the positioning frame is located at the upper end of the bottom frame. The positioning frame and the bottom frame are connected by a connecting rod.

[0007] As a further preferred embodiment, the lower mold positioning mechanism includes positioning pins, which are installed at both ends of the upper mold mounting frame.

[0008] Preferably, the system also includes locking screws. Several locking screws are provided on both sides of the upper mold mounting frame, and a locking plate is provided on the outer edge of the lower mold. The locking plate has locking holes that cooperate with the locking screws.

[0009] As a further preferred embodiment, the upper mold positioning mechanism includes a support base, a cylindrical base, and a cylinder. The support base is installed on the upper end of the bottom frame, and the cylindrical base is provided on the upper end of the support base. Two cylinders are provided on the cylindrical base, and the two cylinders are spaced apart.

[0010] As a further preferred embodiment, the system also includes a guide rod and a top seat, the top seat being mounted on the lower end of the upper mold mounting frame, the guide rod being provided at the lower end of the top seat, the guide rod passing through the gap between the two cylinders and entering the support seat.

[0011] Preferably, the upper mold is a double-layer shell structure with an opening at the top, the lower surface of the upper mold is arc-shaped, the outer edge of the lower end of the upper mold is provided with an arc-shaped surface, and air suction holes are provided on both the arc-shaped surface and the lower surface of the upper mold.

Please refer to [link / reference]. Figures 1 to 7 The image shows a preferred embodiment of a glass pressing mold, including a lower mold 1 and a hot bending mold 2 that cooperates with the lower mold 1. The hot bending mold 2 includes an upper mold 201, a lifting mechanism 202, an upper mold positioning mechanism 203, a lower mold positioning mechanism 204, and an upper mold mounting frame 205. The upper mold 201 is mounted inside the upper mold mounting frame 205 and above the lifting mechanism 202. The lower mold positioning mechanism 204 is mounted at both ends of the upper mold mounting frame 205. The upper mold positioning mechanism 203 is mounted on the upper mold mounting frame 205 and the lifting mechanism 202. In this embodiment, see [reference needed]. Figure 1 As shown, the glass pressing mold is mounted on an external frame 3. A heating device 4 is installed on the frame 3. The upper mold 201, lifting mechanism 202, upper mold positioning mechanism 203, lower mold positioning mechanism 204, and upper mold mounting frame 205 are all installed inside the heating device 4. The lower mold 1 has an existing structure. A conveying mechanism is provided on the frame 3 to transport the lower mold 1, allowing it to enter the heating device 4 and move below the upper mold 201. Then, under the action of the lifting mechanism 202, the lower mold 1 is moved to cooperate with the upper mold 201, thus pressing the glass on the lower mold 1. The upper mold mounting frame 205 is used to connect with the inner wall of the heating device 4.

[0021] Furthermore, as a preferred embodiment, the lifting mechanism 202 includes a linear electric cylinder 206, a bottom frame 207, and a positioning frame 208. The bottom frame 207 is disposed at the upper end of the linear electric cylinder 206, and the positioning frame 208 is disposed at the upper end of the bottom frame 207. The positioning frame 208 and the bottom frame 207 are connected by a connecting rod 218. The linear electric cylinder 206 is fixedly connected to the bottom of the heating device 4, and the output end of the linear electric cylinder 206 is bolted to the bottom frame 207. The linear electric cylinder 206 drives the bottom frame 207 to move up and down, thereby driving the positioning frame 208 to move up and down. The positioning frame 208 is used to cooperate with the lower mold 1 to push the lower mold 1 to move upward.

[0022] Furthermore, as a preferred embodiment, the lower mold positioning mechanism 204 includes positioning pins, which are installed at both ends of the upper mold mounting frame 205. The positioning pins are used to cooperate with positioning holes on the lower mold 1 to achieve precise positioning of the lower mold 1.

[0023] Furthermore, as a preferred embodiment, it also includes locking screws 209. Several locking screws 209 are provided on both sides of the upper mold mounting frame 205, and a locking plate 101 is provided on the outer edge of the lower mold 1. The locking plate 101 has locking holes 102 that cooperate with the locking screws 209. Through the mutual cooperation of the locking screws 209, the locking plate 101, and the locking holes 102, the upper mold 201 and the lower mold 1 can be locked and fixed, enhancing the stability of the mold during the pressing process.

[0024] Furthermore, as a preferred embodiment, the upper mold positioning mechanism 203 includes a support base 210, a cylindrical base 211, and cylinders 212. The support base 210 is installed on the upper end of the bottom frame 207. The cylindrical base 211 is provided on the upper end of the support base 210, and two cylinders 212 are provided on the cylindrical base 211, spaced apart from each other. It also includes a guide rod 213 and a top seat 214. The top seat 214 is installed on the lower end of the upper mold mounting frame 205, and the guide rod 213 is provided on the lower end of the top seat 214. The guide rod 213 passes through the gap between the two cylinders 212 and enters the support base 210, ensuring accurate positioning and stable operation of the upper mold 201 during lifting. This ensures the relative positional accuracy of the upper and lower molds 1 during the pressing process, further improving the precision of glass pressing. Precise positioning ensures uniform stress on multiple pieces of glass during pressing, resulting in glass products with higher dimensional accuracy and more stable quality.

[0025] Furthermore, as a preferred embodiment, the upper mold 201 is a double-layered shell structure with an open top. The lower surface of the upper mold 201 is arc-shaped, and an arc-shaped surface 216 is provided on the outer edge of the lower end of the upper mold 201. Suction holes 215 are provided on both the arc-shaped surface 216 and the lower surface of the upper mold 201, and the suction holes 215 communicate with the interior of the upper mold 201. A connecting flange 217 is provided at the upper end of the upper mold 201 for connecting to an external negative pressure device. When connected to the external negative pressure device via the connecting flange 217, the negative pressure device is activated, and air is drawn out through the suction holes 215, creating a negative pressure between the glass and the upper mold 201, thereby adsorbing the glass onto the upper mold 201. Because the suction holes 215 are distributed over a large arc-shaped area, multiple pieces of glass can be adsorbed simultaneously, breaking the limitation of traditional molds that can only adsorb one piece of glass at a time. This design significantly improves production efficiency, allowing multiple glass sheets to be processed in a single pressing cycle. This reduces the number of cycles for loading, pressing, and unloading, drastically shortening the overall production cycle. Simultaneously, it improves the pressing quality and optical properties of the glass. Furthermore, because multiple glass sheets are pressed simultaneously on the same mold, compared to traditional single-sheet pressing, it reduces errors caused by multiple positioning steps, improves glass pressing precision, and enhances product quality stability.

[0026] The suction hole 215 on the lower surface of the upper mold 201 is used to adsorb the first piece of glass, while the suction hole 215 on the arc surface 216 is used to adsorb the second piece of glass.

[0027] In use, the lower mold 1 is conveyed into the heating device 4 by the external conveying mechanism and enters the positioning frame 208. Then, the lifting mechanism 202 drives the lower mold 1 to move upward. During the movement, the positioning pin engages with the positioning hole on the lower mold 1. At the same time, the guide rod 213 passes through the gap between the two cylinders 212 and enters the support base 210. Simultaneously, the external negative pressure device is activated, which generates negative pressure inside the upper mold 201, adsorbing the two pieces of glass and fixing their position. Then, the lifting mechanism 202 continues to drive the lower mold 1 to move upward, cooperating with the upper mold 201 to press the two pieces of glass.

[0028] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
