Description

Technical Field

[0001] This application relates to the field of mold equipment technology, specifically to a glass mold. Background Technology

[0002] Glass forming is the process of transforming molten glass into a geometrically shaped product; this process is called one-step glass forming or hot-end forming. Glass molds are frequently used in the glass forming process. Traditional glass molds typically have a bottom mold with ejector pins at the bottom to push the formed glass out. However, when the sides of the glass mold are uneven, interference can occur between the mold sides and the formed glass. Directly ejecting the formed glass using ejector pins can damage it.

[0003] Chinese patent (CN222411317U) discloses a glass mold, including a bottom mold with a cavity and a secondary mold with an uneven structure disposed on the side of the bottom mold. The end of the secondary mold near the cavity forms a cavity with the cavity for containing molten glass. The secondary mold is provided with a first fixing block for fixing the secondary mold, and the secondary mold can slide relative to the first fixing block. The bottom of the bottom mold is provided with a top support for vertically lifting the bottom mold. The contact surface between the first fixing block and the secondary mold is inclined relative to the movement direction of the top support to facilitate the movement of the secondary mold. However, this glass mold has the risk of increasing the gap between the bottom mold and the secondary mold after long-term movement. If the gap between the bottom mold and the secondary mold is too large, glass leakage will occur, ultimately leading to a decrease in the product qualification rate.

[0004] In view of this, it is necessary to design a glass mold to solve one of the above problems. Summary of the Invention

[0005] This application provides a glass mold that can effectively prevent the secondary mold from popping open to both sides, thereby effectively improving the quality of the finished glass product.

[0006] To achieve the above objectives, the technical solution provided in this application is as follows:

Detailed Implementation

[0028] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this application.

[0029] It should be noted that the terms "upper" and "lower," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the purpose of simplifying the description of this application and do not indicate or imply that the device referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this application. Specifically, in this application, the direction facing the ground is referred to as "lower," and conversely, the direction away from the ground is referred to as "upper." Other descriptions of orientation are defined based on "upper" and "lower."

[0030] In the various figures of this application, for ease of illustration, certain dimensions of structures or parts may be exaggerated relative to other structural parts; therefore, they are only used to illustrate the basic structure of the subject matter of this application.

[0031] This application provides a glass mold for manufacturing glass products, such as... Figures 1 to 6 As shown, the glass mold includes a mold body 10, a base 20 for fixing the mold body 10, and a limiting component 30 disposed between the mold body 10 and the base 20.

[0032] like Figures 1 to 3 As shown, the mold body 10 includes a bottom mold 11 with a cavity and secondary molds 12 disposed on both sides of the bottom mold 11. The side of the secondary mold 12 closest to the bottom mold 11 has an uneven shape to create a shaped glass product. The side of the secondary mold 12 facing the bottom mold 11 communicates with the cavity to form a cavity for containing molten glass. After the glass product is made, the secondary mold 12 moves away from the bottom mold 11, and the bottom mold 11 moves upward under force, completing the demolding process of the glass product.

[0033] The secondary mold 12 is located on opposite sides of the bottom mold 11. When the glass product has a shape along the circumference, the secondary mold 12 is semi-circular or multiple secondary molds 12 are spaced apart on the side of the bottom mold 11.

[0034] The mold body 10 also includes a ring mold 13 fixedly installed at the upper end of the bottom mold 11 to ensure that the secondary mold 12 is precisely aligned with the bottom mold 11 when closed. In addition, it can also be used to fix or support the limiting component 30.

[0035] like Figures 1 to 6 As shown, the base 20 includes a base plate 21 for fixing the bottom mold 11 and a movable block 22 slidably connected to the base plate 21. The movable block 22 is connected to the secondary mold 12 and is used to move the secondary mold 12 to move closer to or away from the bottom mold 11. Specifically, the movable block 22 has a step 221 on the side facing the secondary mold 12. The secondary mold 12 is disposed on the step 221 and fixed with bolts. Different models of the secondary mold 12 can be replaced as needed to improve the adaptability of the glass mold.

[0036] The base 20 also includes a fixing seat 23 located on the upper part of the base plate 21 for fixing the bottom mold 11, and a bottom support located on the lower part of the base plate 21 and passing through the base plate 21 and connected to the fixing seat 23. During the demolding process of the glass product, the bottom mold 11 is moved upward by the upward external force of the bottom support, thereby completing the demolding process of the glass product.

[0037] During the movement of the secondary mold 12, it rubs against the bottom mold 11. Repeated friction will cause wear at the contact point between the secondary mold 12 and the bottom mold 11, and the gap between the secondary mold 12 and the bottom mold 11 will gradually increase. This will create a gap between the secondary mold 12 and the bottom mold 11, which may lead to leakage of molten glass and thus affect the quality of the glass products.

[0038] The glass mold of this application uses a limiting component 30 to solve the above-mentioned technical problems, such as Figures 1 to 5 As shown, the limiting component 30 includes a stop structure 32 connected to the end of the base plate 21 and a limiting structure 31 for limiting the secondary mold 12. The stop structure 32 is located on the outer side of the moving block 22 along the radial direction of the base plate. The stop structure 32 and the moving block 22 form an insertion groove 33. The limiting structure 31 is inserted into the insertion groove 33 and abuts against the moving block 22 and the stop structure 32 respectively. By limiting the moving block 22, the secondary mold 12 is tightly fitted to the side of the base mold 11, preventing gaps between the secondary mold 12 and the base mold 11.

[0039] The limiting structure 31 is elongated and inserted into the insertion groove 33. Preferably, the limiting structure 31 is detachably installed on the outside of the ring mold 134. After the glass mold is stamped, the limiting structure 31 is effectively inserted into the insertion groove 33 to fix the secondary mold 12 to the side of the bottom mold 11.

[0040] Preferably, such as Figure 4As shown, the limiting structure 31 has a first contact surface 311 that abuts against the moving block 22 and a second contact surface 312 that abuts against the stop structure 32. Correspondingly, the moving block 22 is provided with a first guide surface 222 that cooperates with the first contact surface 311. Preferably, both the first contact surface 311 and the first guide surface 222 are inclined outward and downward to improve the smoothness of the movement of the limiting structure 31.

[0041] To prevent the limiting structure 31 from becoming loose relative to the moving block, the base 20 also includes a friction piece 25 disposed between the limiting structure 31 and the moving block 22 to increase the friction between the first contact surface 311 and the first guide surface 222. The friction piece 25 is disposed on the first contact surface 311 and / or the first guide surface 222, which can achieve the purpose of increasing the friction between the first contact surface 311 and the first guide surface 222.

[0042] In this embodiment, the friction plate 25 is disposed on the first guide surface 222. Specifically, the moving block 22 has a mounting groove 223 for mounting the friction plate 25. The depth of the mounting groove 223 is not greater than the thickness of the friction plate 25. That is, the surface of the friction plate 25 protrudes from the mounting groove 223 to facilitate contact with the first contact surface 311. Preferably, the thickness of the friction plate 25 is 0.5mm-1mm greater than the depth of the mounting groove 223.

[0043] Preferably, the friction plate 25 is installed in the mounting groove 223 by bolts, which facilitates the replacement of a new friction plate 25 after the surface of the friction plate 25 is worn.

[0044] As another preferred embodiment of this application, such as Figures 2 to 5 As shown, the limiting structure 31 includes a limiting body 313 and an auxiliary limiting block 314 detachably mounted on the limiting body 313 near the moving block. The first contact surface 311 is formed on the auxiliary limiting block 314. In an embodiment where the friction plate 25 is disposed on the first contact surface 311, a mounting groove 223 for mounting the friction plate 25 is disposed on the auxiliary limiting block 314.

[0045] In this embodiment, the auxiliary limiting block 314 is bolted to the limiting body 313, making it easy to replace the new auxiliary limiting block 314 after the first contact surface 311 is worn.

[0046] The stop structure 32 is vertically installed on the edge of the base plate 21 and extends in the same direction as the bottom mold 11, that is, the stop structure 32 and the mold body 10 are located on the same side of the base plate 21.

[0047] like Figure 4As shown, the stop structure 32 abuts against the second contact surface 312. Correspondingly, the stop structure 32 has a second guide surface 321 that abuts against the limiting structure 31. Both the second guide surface 321 and the second contact surface 312 are inclined inward and downward, which facilitates cooperation with the stop structure 32 and improves the smoothness of movement of the limiting structure 31.

[0048] In another preferred embodiment of this application, the stop structure 32 includes a stop plate 322 mounted on the base plate 21 and a guide block 323 detachably mounted on the stop plate 322, wherein the second guide surface 321 is formed on the guide block 323. Preferably, the guide block 323 is bolted to the upper end of the stop plate 322, and the guide block 323 can be easily replaced if the second guide surface 321 is worn.

[0049] In this embodiment, the guide block 323 is an isosceles trapezoid, and the second guide surface 321 is the waist surface of the guide block 323. The isosceles trapezoidal guide block 323 has two second guide surfaces 321. When one of the second guide surfaces 321 is worn, the installation direction of the guide block 323 can be reversed to continue using the other second guide surface 32, thereby improving the service life of the guide block 323.

[0050] As another preferred embodiment of this application, such as Figures 1 to 5 As shown, the glass mold also includes a drive assembly 40 for driving the moving block 22 to slide relative to the base plate 21. The drive assembly 40 includes a drive device and a fork 41 connected to the drive device. The fork 41 is connected to the moving block 22 to drive the moving block 22 to slide relative to the base plate 21. The fork 41 can precisely control the moving speed of the moving block 22. The bottom of the moving block 22 is provided with a receiving groove 225 for receiving the fork 41.

[0051] Specifically, the shift fork 41 is provided in pairs, and the base plate 21 is provided with a pair of shift fork grooves 211 that pass through along its thickness direction for the shift fork 41 to pass through, and an intermediate beam 212 between the shift fork grooves 211. The driving device 40 is located at the lower part of the intermediate beam 212. One of the moving block 22 and the intermediate beam 212 is provided with a guide rail 42, and the other is provided with a guide rail groove 224 that cooperates with the guide rail 42, which is conducive to accurately controlling the movement path of the moving block 22.

[0052] In this embodiment, as Figure 6As shown, the guide rail 42 is mounted on the intermediate beam 212, and the base plate 21 also includes a clearance space 213 on the intermediate beam 212 for mounting the guide rail 42. The bottom surface of the moving block 22 is provided with a guide rail groove 224 that cooperates with the guide rail 42.

[0053] In this embodiment, to avoid interference between the moving block 22 and the base plate 21 during movement, such as... Figure 5 As shown, the moving block 22 includes a body 226 and a transition block 227 that is inserted and fixed to the body 226. The guide rail groove 224 is provided on the transition block 227, so that there is a distance between the body 226 and the base plate 21, so as to avoid interference with the base plate 21.

[0054] Of course, the guide rail 42 is located on the moving block 22, and the guide rail groove 224 is located on the intermediate beam 212, which can also achieve the purpose of the moving block 22 being driven by the fork 41 to move relative to the base plate 21.

[0055] In summary, the glass mold of this application, through the mold body 10, the base 20 for fixing the mold body 10, and the limiting component 30 disposed between the mold body 10 and the base 20, limits the secondary mold 12 to the side of the bottom mold 11, preventing the secondary mold 12 from popping outward, thereby avoiding the phenomenon of glass material leakage due to excessive gap between the bottom mold 11 and the secondary mold 12, thus improving the quality of glass products.
