[0002] In the development process of curved screens, in pursuit of beauty, the design forms of curved screens are becoming more and more diverse, and large-size, high-arc, and special-shaped curved screen products have appeared one after another. Facing large-size special-shaped curved screen products, hot bending molding faces huge challenges.

[0003] The shape of the curved screen is generally formed by hot pressing of a glass bending mold. However, when the existing glass bending mold is used for hot bending of the curved screen, the upper mold and the lower mold of the glass bending mold are prone to tilting. In particular, when the curved screen product to be formed is a convex mirror, if the lower mold is a convex mold, it is difficult to ensure balance when the glass plate is placed on the convex mold of the lower mold. On this basis, when the upper mold is placed on the glass plate, it is easy to cause the upper mold and the lower mold to tilt when pressed together, and when the upper mold is pressed down relative to the lower mold, it is also easy to cause problems such as glass plate fragments and unstable molding.

[0017] In one embodiment, one of the first mold-matching configuration and the second mold-matching configuration is configured as a concave mold-matching surface, and the other is configured as a convex mold-matching surface, and the concave mold-matching surface and the convex mold-matching surface are relatively assembled to form a curved preset mold-matching space;

[0045] In addition, if the terms "first" or "second" appear, these terms are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0046] In this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", "connected", "fixed" and the like appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined.

If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only implementation method.

[0049] See also Figures 1 to 11 As shown, a glass bending mold provided by the present application includes a first mold unit body 1000 and a second mold unit body 2000. The first mold unit body 1000 and the second mold unit body 2000 can be used as an upper mold and a lower mold of the glass bending mold, respectively. For example, the first mold unit body 1000 is used as an upper mold of the glass bending mold, and the second mold unit body 2000 is used as a lower mold of the glass bending mold, or the first mold unit body 1000 is used as a lower mold of the glass bending mold, and the second mold unit body 2000 is used as an upper mold of the glass bending mold. Those skilled in the art can choose according to their needs, and this is not limited here.

[0050] In the first mold unit, the first mold unit body 1000 has a first mold surface 1100, and a first mold configuration with a specific shape can be provided on the first mold surface 1100. In the second mold unit, the second mold unit body 2000 has a second mold surface 2100, and a second mold configuration with a specific shape can be provided on the second mold surface 2100. The first mold configuration of the first mold surface 1100 and the second mold configuration of the second mold surface 2100 are used to relatively combine to form a preset mold space, and the preset mold space can be formed based on the specific shape of the first mold configuration and the specific shape of the second mold configuration. For example, in one embodiment, one of the first mold configuration and the second mold configuration is configured as a concave mold surface, and the other is configured as a convex mold surface. Therefore, the concave mold surface and the convex mold surface are relatively combined to form a curved preset mold space. In addition, those skilled in the art may also construct a preset spatial shape of the mold space according to actual needs, thereby hot pressing the glass sheet into a specific shape, which is not limited here.

[0051] The glass hot bending mold also includes a mold closing guide structure 3000, which can be set in at least one of the first mold unit body 1000 and the second mold unit body 2000. At this time, a mold closing motion trajectory 3000a can be defined between the first mold unit body 1000 and the second mold unit body 2000. The mold closing motion trajectory 3000a is not a physical trajectory, but a virtual trajectory defined to limit the mutual movement between the first mold unit body 1000 and the second mold unit body 2000. The mold closing motion trajectory 3000a can be set to a straight line trajectory. The mold closing motion trajectory 3000a is perpendicular to the first mold closing surface 1100 of the first mold unit body 1000 and the second mold closing surface 2100 of the second mold unit body 2000. Therefore, the first mold unit body 1000 and the second mold unit body 2000 can move in a straight line along the straight line trajectory. In addition, technical personnel in this field can also set the mold closing motion trajectory 3000a to other shapes according to needs, which is not limited here.

[0052] As can be seen from the above, after the mold clamping guide structure 3000 is set, the first mold unit body 1000 and the second mold unit body 2000 can be guided to move relative to each other through the mold clamping guide structure 3000, that is, the mutual guided movement of the first mold unit body 1000 and the second mold unit body 2000 through the mold clamping guide structure 3000 is limited to the first mold unit body 1000 and the second mold unit body 2000 moving relative to each other along the mold clamping motion trajectory 3000a. Therefore, based on the guiding function of the mold clamping guide structure 3000, the first mold unit body 1000 and the second mold unit body 2000 can be limited to move relative to each other along the only mold clamping motion trajectory 3000a, even if uneven force occurs during the process of pressing the glass plate, there will be no movement that deviates from each other, that is, the mold clamping guide structure 3000 can limit the first mold unit body 1000 and the second mold unit body 2000 to move relative to each other strictly along the only mold clamping motion trajectory 3000a.

[0053] With the help of the mold closing guide structure 3000, for example, when a glass hot bending mold is used to hot-bend a curved screen, even if the curved screen product to be formed is a convex mirror, the glass plate is placed on the male mold of the lower mold, and the upper mold is placed on the glass plate. After the upper mold and the lower mold are assembled through the mold closing guide structure 3000, the upper mold and the lower mold will strictly move relative to each other along the unique mold closing motion trajectory 3000a, and will not tilt during the pressing process, thereby avoiding problems such as glass plate fragments and unstable molding.

[0054] The mold closing guide structure 3000 may adopt a variety of structures with guiding functions. The mold closing guide structure 3000 may be only arranged on the first mold unit body 1000 or only arranged on the second mold unit body 2000, or in one embodiment, the mold closing guide structure 3000 includes a first guiding unit body 3100 and a second guiding unit body 3200, the first guiding unit body 3100 is arranged on the first mold closing surface 1100 of the first mold unit body 1000, and the second guiding unit body 3200 is arranged on the second mold closing surface 2100 of the second mold unit body 2000. At this time, the first guiding unit body 3100 of the first mold unit body 1000 and the second guiding unit body 3200 of the second mold unit body 2000 can be used for mutual guiding assembly along the mold closing motion trajectory 3000a. Therefore, the first mold unit body 1000 and the second mold unit body 2000 can indirectly realize mutual guiding assembly through the mutual guiding assembly between the first guiding unit body 3100 and the second guiding unit body 3200, that is, they move relative to each other along the preset mold closing motion trajectory 3000a.

[0055] The first guide unit body 3100 and the second guide unit body 3200 can be set to a variety of guideable shapes, structures, etc., and realize mutual guiding cooperation through specific structures, surfaces, etc. For example, in one embodiment, the first guide unit body 3100 has a first guide surface 3110, and the second guide unit body 3200 has a second guide surface 3210. The first guide surface 3110 of the first guide unit body 3100 and the second guide surface 3210 of the second guide unit body 3200 are used for mutual guiding and sliding cooperation along the mold clamping motion track 3000a. Therefore, the first guide unit body 3100 and the second guide unit body 3200 can indirectly realize mutual guiding assembly through the mutual guiding and sliding cooperation between the first guide surface 3110 and the second guide surface 3210, that is, mutual movement along the preset mold clamping motion track 3000a.

[0056] In one embodiment, the first guide unit body 3100 can be configured as a first guide enclosure wall surrounding the first mold surface 1100, in which case the inner wall surface of the first guide enclosure wall is configured to constitute a first guide surface 3110, and the second guide unit body 3200 can be configured as a second guide enclosure wall surrounding the second mold surface 2100, in which case the outer wall surface of the second guide enclosure wall is configured to constitute a second guide surface 3210.

[0057] In one embodiment, the first guide enclosure wall is a circular wall that completely surrounds the first mold surface 1100, and the second guide enclosure wall is a circular wall that completely surrounds the second mold surface 2100, or the first guide enclosure wall is an arcuate wall that does not completely surround the first mold surface 1100, and the second guide enclosure wall is an arcuate wall that does not completely surround the second mold surface 2100. Those skilled in the art can set the actual structure of the first guide unit body 3100 and the second guide unit body 3200 according to actual conditions, as long as the mutual guiding sliding fit between the first guide unit body 3100 and the second guide unit body 3200 is satisfied, and no limitation is made here.

[0058] In one embodiment, the first guide surface 3110 of the first guide unit body 3100 may be provided with a first interlocking structure 3120, and the second guide surface 3210 of the second guide unit body 3200 may be provided with a second interlocking structure 3220. The first interlocking structure 3120 and the second interlocking structure 3220 may be used to slide and fit with each other along the mold clamping motion trajectory 3000a. Therefore, when the first guide unit body 3100 and the second guide unit body 3200 are guided and slidably fitted with each other through the first guide surface 3110 and the second guide surface 3210, The first interlocking structure 3120 and the second interlocking structure 3220 can be relatively interlocked and assembled. Therefore, as the first guide surface 3110 and the second guide surface 3210 guide and slide with each other, the first interlocking structure 3120 and the second interlocking structure 3220 can also be slidably interlocked and assembled with each other along the mold closing motion trajectory 3000a, thereby improving the stability of the relative movement of the first mold unit body 1000 and the second mold unit body 2000, and ensuring that the first mold unit body 1000 and the second mold unit body 2000 strictly move relative to each other along the mold closing motion trajectory 3000a.

[0059] The first interlocking structure 3120 and the second interlocking structure 3220 can be configured to be a variety of shapes such as grooves, protrusions, holes, columns, etc. that can be interlocked with each other, which are not limited here. For example, in one embodiment, the first interlocking structure 3120 includes at least one first interlocking groove 3120a and at least one first interlocking protrusion 3120b provided on the first guide surface 3110 of the first guide unit body 3100, and the second interlocking structure 3220 includes at least one second interlocking groove 3220a and at least one second interlocking protrusion 3220b provided on the second guide surface 3210 of the second guide unit body 3200, and the first interlocking groove 3120a and the second interlocking protrusion 3220b are used to slide and interlock with each other along the mold clamping motion trajectory 3000a, and the first interlocking protrusion 3120b and the second interlocking groove 3220a are used to slide and interlock with each other along the mold clamping motion trajectory 3000a.

[0060] In one embodiment, the first mold unit body 1000 has a third mold surface, the surface of the third mold surface faces away from the surface of the first mold surface 1100, and the third mold surface is provided with a first exhaust structure 1200, for example, the first exhaust structure 1200 can be configured as a first exhaust groove opened on the third mold surface, and the first exhaust groove can be set in a variety of shapes, for example, the first exhaust groove is set in a cross shape, etc., which is not limited to this. The second mold unit body 2000 has a fourth mold surface, the surface of the fourth mold surface faces away from the surface of the second mold surface 2100, and the fourth mold surface is provided with a second exhaust structure 2200, for example, the second exhaust structure 2200 can be configured as a second exhaust groove opened on the fourth mold surface, and the second exhaust groove can be set in a variety of shapes, for example, the second exhaust groove is set in a cross shape, etc., which is not limited to this.

[0061] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0062] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
