AI Technical Summary
Existing hot-bending double-curved glass molds suffer from dimensional instability due to wear and thermal expansion during use, affecting product quality and production efficiency. Furthermore, frequent mold replacements increase material costs.
Insert slots are set on the lower mold body and movable inserts are installed. The hot bending dimensions are stabilized by adjusting the width of the inserts, thus avoiding frequent mold changes.
Improve product dimensional accuracy, reduce material consumption costs, increase production efficiency, and reduce mold replacement frequency.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to glass mould technical field, concretely is a hot bending two curved glass mould. BACKGROUND
[0002] In the glass hot bending production process, the common mould has certain defects, the original common mould lower mould does not have inlay piece, in the production process, along with the mould use time growth, the mould can wear and tear, and the uneven heating temperature leads to the mould width bigger length smaller, and the expansion is inconsistent, this makes the glass size unstable when hot bending, the big and small situation is difficult to control, influences product quality, this condition not only leads to the product size in the production process defective rate higher, moreover after the mould size changes, often needs to make the mould again, this not only increases the material consumption cost, also reduces the production efficiency.
[0003] Therefore, research and development a kind of hot bending two curved glass mould that can solve the above problems become the urgent needs in industry. UTILITARY MODEL CONTENT
[0004] The utility model provides a hot bending two curved glass mould to solve the technical problem in the prior art.
[0005] To solve the above technical problems, the utility model adopts the technical scheme of a kind of hot bending two curved glass mould, including lower mould body, the top of the lower mould body starts to have forming groove, the front and back sides of the forming groove are all provided with inlay piece groove, the inside of the inlay piece groove is provided with inlay piece.
[0006] Preferably, the number of inlay pieces is two, and the two inlay pieces are arranged in the inside of the two inlay piece grooves.
[0007] Preferably, the length of the inlay piece groove is 70.65mm, 6.02mm and 5mm respectively.
[0008] Preferably, the length, width and height of the inlay piece are 70.60mm, 6mm and 10.77mm respectively.
[0009] The utility model adopts the above technical scheme, which can bring the following beneficial effects:
[0010] The hot bending two curved glass mould increases two movable inlay pieces on the lower mould body, when the size is unstable due to the wear and tear and the expansion change of the lower mould body, the hot bending size can be effectively stabilized by adjusting the width of the inlay piece, thereby improving the product size precision and the hot bending size yield, and avoiding the need to make a new mould due to the change of the mould size. DRAWING EXPLANATION
[0011] Fig. 1The utility model discloses a whole structure schematic diagram.
[0012] Fig. 2 The utility model discloses a structure schematic diagram of insert groove.
[0013] In the drawing: 1, lower mould body, 2, forming groove, 3, insert groove, 4, insert. Specific embodiments
[0014] The technical scheme in the embodiments of the utility model will be apparently and completely described in combination with the drawings in the embodiments of the utility model, and apparently, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without making creative efforts are within the protection scope of the utility model.
[0015] In the description of the utility model, it is understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element indicated must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model.
[0016] In the description of the utility model, it is understood that, unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "setting" should be understood broadly, for example, can be fixedly connected, set, or detachably connected, set, or integrally connected, set. For the person skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.
[0017] In addition, the terms "first", "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first", "second" can explicitly or implicitly include one or more features. In the description of the utility model, the meaning of "several" is two or more than two, unless otherwise explicitly specified and limited.
[0018] Please refer to Figs. 1-2The utility model discloses a kind of hot bending two-curved glass moulds, including lower mould body 1, the top of lower mould body 1 starts to have forming groove 2, forming groove 2 is provided with insert groove 3 in front and back sides, insert groove 3 is provided with insert 4 inside, the quantity of insert 4 is two, two inserts 4 are respectively arranged in the inside of two insert grooves 3, the length of insert groove 3 is respectively 70.65mm, 6.02mm, 5mm, the length of insert 4 is respectively 70.60mm, width 6mm, 10.77mm.
[0019] Working principle: by increasing two movable inserts 4 on lower mould body 1, when lower mould body 1 is worn and size is unstable due to thermal expansion change, the width of insert 4 can be adjusted (insert 4 height 10.77mm, insert 3 on lower mould body 1 is inserted into 5mm, the whole length of higher part 5.77mm can be modified according to the size of product after heat bending), effectively stabilize heat bending size, so as to improve product size precision, improve heat bending size yield, avoid the situation that new mould needs to be made due to mould size change, improve heat bending size by replacing insert 4, so that lower mould body 1 can be used continuously, thereby reducing material consumption cost, about 40% or so can be reduced, since new mould does not need to be made frequently, reduce the influence of mould manufacturing cycle on production, make production process more continuous, and further improve production efficiency.
[0020] The utility model provides a kind of hot bending two-curved glass mould, the method and approach of specific implementation this technical scheme are many, above is only the preferred implementation mode of the utility model, it should be pointed out, for the ordinary skilled in the art of this technology, under the premise of not departing from the principle of the utility model, still can make several improvements and refinements, these improvements and refinements also should be regarded as the protection scope of the utility model.
