DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0031] The disclosure is described in detail below in combination with FIGS. 1 to 4.

[0032] It should be noted that all directional indications (such as up, down, left, right, front, rear, inside, outside, top, bottom, . . . ) in the embodiment of the disclosure are only used to explain the relative position relationship among the components under a certain attitude (as shown in the attached figures), etc. if the specific attitude changes, the directivity indication will change accordingly.

[0033] It should also be noted that when a component is called fixed to or disposed on another component, the component can directly interacts with another component or there may be an intermediate component at the same time. When a component is referred to as connecting to another component, it can be directly connected to another component or there may be an intermediate component at the same time.

[0034] As shown in FIGS. 1-4, the disclosure provides a glass forming device comprising a driving mechanism and a glass product forming mold 100. The glass product forming mold 100 comprises a mold body 10 and a plurality of sliding blocks 20 slidably mounted on the mold body 10, the driving mechanism is configured to drive the plurality of sliding blocks 20 to radially slide with respect to the mold body 10. Each of the plurality of sliding blocks 20 comprises a first inclined surface 21, the plurality of sliding blocks 20 are configured to be inserted between the glass product 200 and the mold body 10 through the plurality of the first inclined surfaces 21 to separate the glass product 200 from the mold body 10.

[0035] Preferably, a second inclined surface 201 facing the mold body 10 is disposed at an edge of the glass product 200. The second inclined surface 201 facilitates the plurality of sliding blocks 20 to be inserted between the glass product 200 and the mold body 10. When the glass product 200 is formed, the driving mechanism drives the plurality of sliding blocks 20 to radially slide with respect to the mold body 10, and the plurality of sliding blocks 20 is inserted between the glass product 200 and the mold body 10 via the plurality of first inclined surfaces 21 and the second inclined surface 201 to separate the glass product 200 from the mold body 10.

[0036] In at least one exemplary embodiment, the driving mechanism is configured to drive the plurality of sliding blocks 20 to slide towards or away from a central axis of the mold body 10, that is, to slide towards or away from the glass product 200. When the glass product 200 is formed, the driving mechanism is controlled to drive the plurality of sliding blocks 20 to slide towards the glass product 200, so that the plurality of sliding blocks 20 can be inserted between the glass product 200 and the mold body 10 via the plurality of first inclined surfaces 21. With the sliding of the slide blocks 20, the slide blocks 20 tend to lift the glass product 200 to separate the glass product 200 from the mold body 10.

[0037] In at least one exemplary embodiment, because the glass product 200 does not contact the mold body 10, a deformation of the glass product 200 due to the uneven heat distribution or excessive adhesion caused by the contact between the glass product 200 and the mold body 10 during the cooling process is avoided, and the quality of the glass product 200 is assured. Besides, because the glass product 200 does not contact the mold body 10, the cooling speed of the glass product 200 is accelerated, which can shorten the production cycle of the glass product 200, and the glass product 200 will not be hindered by the mold body 10 during the process of cooling shrinkage, so as to avoid the risk of cracking of the glass product 200 due to the different thermal expansion coefficients of the mold body 10 and the glass product 200. The thermal expansion coefficient refers to the expansion and contraction of an object due to the change of temperature. The larger the thermal expansion coefficient is, the greater the shrinkage degree will be.

[0038] Specifically, in one exemplary embodiment, the shape of the glass product 200 is approximately a circular table, and the shape of the mold body 10 is cylindrical.

[0039] Preferably, each first inclined surface 21 is planar, which is easy to shape.

[0040] Understandably, the first inclined surface 21 is not limited to a plane, for example, it can also be a surface or a combination of a plane and a surface.

[0041] Preferably, in one exemplary embodiment, the glass product forming mold 100 comprises four sliding blocks 20 equidistantly surrounding the mold body 10, and a distance between each two neighbouring sliding blocks 20 is the same.

[0042] Four equidistant sliding blocks 20 can lift each part of the glass product 200 simultaneously, avoiding the problem that one end of the glass product 200 is disconnected from the mold body 10, while the other end is still in contact with the mold body 10. Understandably, four sliding blocks 20 equidistantly and separately surrounding the mold body 10 make the glass product 200 evenly stressed during the lifting process of the glass product 200, so as to prevent the glass product 200 from cracking due to uneven stress.

[0043] Understandably, the number of the sliding blocks 20 is not limited to four, for example, two, three or more other numbers are also possible.

[0044] The disclosure also provides a method of processing a glass product 200, the method comprising:

[0045] providing the aforesaid glass product forming mold 100 and a glass substrate;

[0046] placing the glass substrate in the glass product forming mold 100 to form a glass product 200 at a temperature higher than a glass transition temperature of the glass product 200;

[0047] driving the plurality of sliding blocks 20 to slide towards the central axis of the mold body 10 by the driving mechanism when a temperature of the glass product 200 drops in the glass transition temperature and prior to complete cooling of the glass product 200, to enable the plurality of sliding blocks 20 to be inserted between the glass product 200 and the mold body 10 via the plurality of first inclined surfaces 21 and slides to lift the glass product 200, so as to separate the glass product 200 from the mold body 10; and cooling the glass product 200;

[0048] removing the glass product 200 after the glass product 200 is cooled, and driving the sliding blocks 20 to slide away from the central axis of the mold body 10 until the sliding blocks 20 return to the original position.

[0049] The glass transition temperature refers to a temperature at which the glass can transform from a high elastic state to a glass state or from a glass state to a high elastic state. The glass product 200 is in a high elastic state in the environment higher than the glass transition temperature. At this time, the glass product is easily deformed in the presence of an external force; the glass product 200 is in a glass state in the environment lower than the glass transition temperature. At this time, the glass product has certain rigidity, it is difficult to deform even in the presence of an external force. Therefore, only when the temperature of the glass product 200 drops below the glass transition temperature, can the sliding blocks 20 be driven to slide, so as to avoid the deformation of the glass product 200 caused by the random sliding of the sliding blocks 20. Besides, the glass product 200 is disconnected from the mold body 10 before it is completely cooled, which can eliminate the influence of the mold body 10 on the later cooling of the glass product 200, and can accelerate the cooling speed of the glass product 200 and shorten the production cycle.

[0050] The above embodiments are only the preferred embodiments of the disclosure, and do not limit the scope of the disclosure. A person skilled in the art may make various other corresponding changes and deformations based on the described technical solutions and concepts. And all such changes and deformations shall also fall within the scope of the present disclosure.
