It not only carries the display function of driving information, but also becomes a key element to improve driving experience and interior aesthetics. Traditional automobile central control screens usually adopt a flat design, but with the users' pursuit of interior aesthetics, curved central control screens have gradually become the new favorite of the market. The design of the curved central control screen can not only provide a wider field of view, but also coordinate with other curved elements in the car to create a more harmonious and smooth interior atmosphere.

When making the curved cover plate, a specific mold is required. In the existing technology, the upper mold is mostly an integrated design, that is, the entire upper mold directly presses down to form the material, but this method is easy to cause the cover plate to move during the forming process, affecting the quality and appearance of the product. Therefore, we have made improvements to this and proposed a segmented mold for making curved cover plates.

[0004] For example, a Chinese patent (publication number CN113878860A) discloses a bonding device for bonding a curved cover plate and a functional membrane, the bonding device comprising: a first mold and a second mold; the first mold is provided with a groove, and the shape of the groove is adapted to the curved cover plate, and is configured to accommodate the curved cover plate; the second mold is provided with a contoured pad and a movable pad; the contoured pad is configured to place the functional membrane; the contoured pad is also configured to occupy the groove after the first mold and the second mold are molded together, and squeeze the curved cover plate and the functional membrane; the movable pad is arranged in the contoured pad, and the movable pad is configured to move toward the first mold after the contoured pad occupies the groove, and exert a force on the contoured pad to squeeze the arc area of ​​the curved cover plate and the functional membrane. The above patents can prove the defects of the prior art. Utility Model Content

[0036] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0037] Embodiment 1 of the segmented mold for making a curved cover plate of the utility model

[0038] Please refer to Figure 1-Figure 2 The utility model discloses a segmented mold for making a curved cover plate, comprising: a lower mold body 1 and an upper mold body 2 arranged above the lower mold body 1. The upper mold body 2 is segmented, and the upper mold body 2 comprises a fixed mold 201 and two molding molds 202 respectively arranged on both sides of the fixed mold 201. The fixed mold 201 descends before the molding mold 202 to fix the curved cover plate before processing. The upper mold body 2 in the present application is segmented. During the processing, the fixed mold 201 descends before the molding mold 202 to fix the curved cover plate before processing, thereby ensuring that the cover plate remains stable during the molding process, obtaining a glass cover plate with a specified curve, improving product quality, and solving the problem of easy movement of the curved cover plate during the molding process in the prior art.

[0039] Further, such as Figure 1-Figure 2 As shown, both sides of the top of the lower mold body 1 are fixedly connected with limiting plates 101, and the two limiting plates 101 are used to limit the curved cover plate, that is, after the curved cover plate is placed on the top of the lower mold body 1, the curved cover plate can be limited by the two limiting plates 101 to improve the stability of the curved cover plate.

[0040] After the curved cover plate is placed on the top of the lower mold body 1, the fixed mold 201 first descends to fix the curved cover plate, and then the two forming molds 202 descend to stamp and form the curved cover plate.

[0041] Embodiment 2 of the segmented mold for making a curved cover plate according to the utility model

[0042] The utility model further provides a segmented mold for making a curved cover plate. Figure 3 As shown, a connecting plate 4 is installed between the two molding molds 202, and a mounting seat 5 is installed on the connecting plate 4 and the fixed mold 201. A through hole is provided on the mounting seat 5. The mounting seat 5 is used to realize the connection between the fixed mold 201 and the connecting plate 4 and the hydraulic system, so that the hydraulic system can drive the fixed mold 201 and the molding mold 202 to rise and fall.

[0043] Furthermore, the connecting plate 4 is used for synchronous lifting and lowering of the two molding dies 202, and the two mounting seats 5 are respectively used for fixing the mold 201 and the connection between the connecting plate 4 and the driving system.

[0044] Further, such as Figure 3 As shown, a limit member is arranged between the fixed mold 201 and the molding mold 202, and the limit member is used to limit the fixed mold 201 and the molding mold 202 when they are raised or lowered. The arrangement of the limit member can improve the stability of the connection between the molding mold 202 and the fixed mold 201, and reduce the offset between the molding mold 202 and the fixed mold 201 due to the successive movement.

[0045] Further, such as Figure 3 As shown, the limiting part includes a T-shaped groove opened on the side of the fixed mold 201 close to the forming mold 202, and a T-shaped limiting strip 3 is slidably connected in the T-shaped groove. The T-shaped limiting strip 3 is fixedly installed on the side of the forming mold 202 close to the fixed mold 201. Through the mutual cooperation of the T-shaped groove and the T-shaped limiting strip 3, the stability of the connection between the forming mold 202 and the fixed mold 201 can be improved, and the offset between the forming mold 202 and the fixed mold 201 due to the successive movement can be reduced.

[0046] Embodiment 3 of the segmented mold for making a curved cover plate of the utility model

[0047] The utility model further provides a segmented mold for making a curved cover plate. Figure 4-Figure 7 As shown, a discharge mechanism 6 is provided in the middle of the lower mold body 1, and the discharge mechanism 6 is used for discharging the curved cover plate after it is processed and formed, that is, after the curved cover plate is processed and formed, the curved cover plate can be lifted upward to realize the discharge of the curved cover plate.

[0048] Further, such as Figure 4-Figure 5 As shown, the discharging mechanism 6 includes a groove 601 formed on the lower mold body 1 , a limit frame 602 and a support plate 603 located below the limit frame 602 are fixedly installed in the groove 601 .

[0049] Further, such as Figure 6-Figure 7As shown, a cylinder 604 is installed at the bottom of the support plate 603, and the piston rod of the cylinder 604 passes through the support plate 603 and is fixedly connected to the first connecting seat 605, the first connecting seat 605 is hinged to the second connecting seat 606, the top of the second connecting seat 606 passes through the limit frame 602 and is fixedly connected to the discharge plate 607, and the second connecting seat 606 is located at a non-center position at the bottom of the discharge plate 607. This arrangement allows the discharge plate 607 to tilt after the cylinder 604 pushes the discharge plate 607 to rise, so that the curved cover plate can slide off the discharge plate 607 to realize the discharge of the curved cover plate.

[0050] Further, such as Figure 7 As shown, a first limiting rod 608 is fixedly installed at the bottom of the second connecting seat 606, and a second limiting rod 609 is fixedly installed on one side of the first connecting seat 605. The first limiting rod 608 and the second limiting rod 609 can limit the second connecting seat 606, and then limit the inclination angle of the discharge plate 607 to prevent the discharge plate 607 from tilting excessively and affecting subsequent resetting.

[0051] After the curved cover plate is processed and formed, the cylinder 604 pushes the first connecting seat 605, the second connecting seat 606 and the discharge plate 607 to rise, and the discharge plate 607 lifts the curved cover plate, and then the discharge plate 607 tilts to make the curved cover plate slide down to realize discharge. After the discharge is completed, the cylinder 604 drives the first connecting seat 605 to descend and reset. During the reset process, the discharge plate 607 returns to the horizontal state under the limit of the limit frame 602.
