Description

Technical Field

[0001] This utility model relates to the field of glass forming mold production, and in particular to a positioning tool for processing oblique holes on the top surface of a glass forming mold. Background Technology

[0002] In glass forming molds, micropores are needed to allow the glass material to fit snugly against the mold cavity, and air is released during the forming process.

[0003] The micro-holes have a small diameter, typically around 0.7 mm. Therefore, downward-extending angled holes need to be machined on the top surface of the glass forming mold. The diameter of these angled holes is larger than that of the micro-holes, and they connect to multiple micro-holes below for venting. To avoid navigating the mold cavity, the angled holes are angled relative to the centerline of the cavity, creating a clamping problem for the drilling machine used to machine these holes, which requires improvement. Utility Model Content

[0004] The main technical problem solved by this utility model is to provide a positioning fixture for processing the oblique hole on the top surface of a glass forming mold, thereby clamping and positioning the glass forming mold and improving the processing convenience of the oblique hole on the top surface.

[0005] To solve the above-mentioned technical problems, the present invention provides a positioning fixture for processing oblique holes on the top surface of a glass forming mold, comprising: a base plate, a support plate, a positioning block, and an arc-shaped panel. The support plate is rotatably mounted on the base plate, and the positioning block is mounted on the support plate. A V-shaped groove is recessed on the front side of the positioning block. The glass forming mold is placed on the support plate, and the back side of the glass forming mold contacts the inner wall of the V-shaped groove. An arc-shaped rib is provided on the back side of the glass forming mold above the positioning block, and an arc-shaped groove is recessed at the bottom of the arc-shaped rib. The arc-shaped panel abuts against the back side of the glass forming mold, and the top of the arc-shaped panel extends into the arc-shaped groove for radial positioning of the glass forming mold. A vertical plate is provided on the positioning block behind the arc-shaped panel. A first stud is provided on the back side of the arc-shaped panel, extending backward through the vertical plate. A first U-shaped groove corresponding to and extending vertically is provided on the vertical plate. First nuts are provided on both sides of the vertical plate on the first stud.

[0006] In a preferred embodiment of the present invention, a first pin seat is provided on the substrate, and a first pin shaft located in the first pin seat is provided at the tail of the tray.

[0007] In a preferred embodiment of the present invention, a second pin seat is provided at the front end of the substrate, a second pin shaft is provided in the second pin seat, and a second stud is provided on the second pin shaft that extends radially and penetrates upward through the support plate.

[0008] In a preferred embodiment of the present invention, the support plate is provided with a second U-shaped groove corresponding to the second stud, and the second stud is provided with a first ball and a second nut located below the second U-shaped groove.

[0009] In a preferred embodiment of the present invention, the second stud is provided with a second ball located above the second U-shaped groove and a third nut.

[0010] In a preferred embodiment of this utility model, the arc-shaped groove is concentric with the outer wall of the glass forming mold.

[0011] In a preferred embodiment of this utility model, the arc panel and the first stud are fixed by thread or welding.

[0012] In a preferred embodiment of this utility model, the bottom of the vertical plate is welded and fixed to the top of the positioning block.

[0013] The beneficial effects of this utility model are as follows: The positioning fixture for processing oblique holes on the top surface of a glass forming mold, as indicated by this utility model, enables the self-centering of the glass forming mold through the V-groove on the positioning block, and strengthens the positioning of the glass forming mold by utilizing the cooperation between the arc panel and the arc groove. This not only does not affect the circumferential rotation adjustment of the glass forming mold, but also avoids the radial outward movement of the glass forming mold, ensuring the fit between the back of the glass forming mold and the V-groove, thus improving the stability during the processing of oblique holes on the top surface. Furthermore, the angle of the positioning block can be adjusted by flipping the support plate up and down to adapt to the angle of the oblique hole, satisfying the processing of oblique holes at various angles.

[0019] like Figure 1 The positioning fixture for machining the oblique hole on the top surface of the glass forming mold shown includes: a base plate 1, a support plate 2, a positioning block 5, and an arc panel 10. The base plate 1 is mounted on the worktable of the drilling machine and can be fixed with screws, making the structure stable.

[0020] The tray 2 is rotatably mounted on the base plate 1. In this embodiment, the base plate 1 is provided with a first pin seat 3, and the tail of the tray 2 is provided with a first pin 4 located in the first pin seat 3, so that the tray 2 can be rotated up and down around the first pin 4.

[0021] A second pin seat 21 is provided at the front end of the substrate 1. A second pin shaft 20 is provided in the second pin seat 21. A second stud 14 is provided on the second pin shaft 20, which extends radially and passes through the support plate 2. In this embodiment, a second U-shaped groove 17 corresponding to the second stud 14 is provided on the support plate 2, which does not affect the angle change of the second stud 14.

[0022] A first ball 18 and a second nut 19 are provided on the second stud 14, located below the second U-shaped groove 17, as follows: Figure 2 As shown, the position and height of the first ball 18 on the stud 14 are changed by rotating the second nut 19, thereby changing the flipping angle of the tray 2. In addition, a second ball 16 and a third nut 15 are provided on the second stud 14 above the second U-shaped groove 17. By rotating the third nut 15, the second ball 16 is pressed and locked, and the second ball 16 locks the tray 2 after the angle is adjusted, preventing it from loosening.

[0023] Positioning block 5 is placed on tray 2. A V-shaped groove is recessed on the front of positioning block 5. Glass forming mold 13 is placed on tray 2, with the back of glass forming mold 13 contacting the inner wall of the V-shaped groove. The V-shaped groove is adaptable to different models of glass forming mold 13, allowing for self-centering of the glass forming mold 13. The bottom of positioning block 5 can be fixed to tray 2 with screws, ensuring a robust structure.

The curved panel 10 can be replaced to accommodate different outer wall radii of the glass forming mold 13. The cooperation between the curved panel 10 and the curved groove 11 ensures the fit between the back of the glass forming mold and the V-groove, improving stability during the machining of the top-surface oblique holes without affecting the rotation of the glass forming mold. This allows for switching to different oblique hole positions and rapid drilling.

[0026] A vertical plate 6 is provided on the positioning block 5, located behind the curved panel 1. The bottom of the vertical plate 6 can be welded to the top of the positioning block 5, resulting in a stable structure. A first stud 8 extending rearward through the vertical plate 6 is provided on the back of the curved panel 10. The curved panel 10 and the first stud 8 are fixed by thread or welding, resulting in a robust structure and good synchronization. In this embodiment, a first U-shaped groove 9 corresponding to and extending vertically on the vertical plate 6 is provided, which does not affect the height adjustment of the first stud 8 and the curved panel 10, so as to adapt to the curved groove 11 on the glass forming mold 13 of different heights.
