Description

Technical Field

[0001] The invention relates to the technical field of graphite moulds, and in particular to a sandwich graphite mould for forming curved glass. Background Art

[0002] Graphite has chemical stability, is not easily infiltrated by molten glass, does not change the composition of glass, has good heat shock resistance, and has small size changes with temperature. Therefore, it has become an indispensable mold material in glass manufacturing in recent years. It can be used to make molds for glass tubes, curved tubes, funnels and other special-shaped glass bottles. In the process of making curved glass, the molten glass needs to be injected into the sandwich graphite mold through the injection port to form it. After the glass is cooled and formed, the mold can be disassembled and the formed glass can be taken out.

[0003] The connection between the traditional graphite mold and the mother mold is mostly threaded, that is, the mold is fixed by using a large diameter, small pitch, and high strength thread. Depending on the installation mode, there are usually template type, seat type, chamfered type, etc.

[0004] Although the threaded fixing method can stably fix the sub-mold and the mother mold of the mold as one, the threaded connection method is relatively cumbersome, and the staff often need to use tools when connecting the sub-mold and the mother mold. Therefore, the traditional graphite mold can be improved to make it easier and faster to install or disassemble, thereby reducing the burden on the staff. Summary of the invention

[0005] The purpose of the present invention is to solve the above problems and to propose a sandwich graphite mold for curved glass molding.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: A sandwich graphite mold for curved glass molding, comprising: Mold body 1, wherein mold body 1 and mold body 2 constitute a complete mold, and mold body 1 is provided with pouring gate 1, and mold body 2 is provided with pouring gate 2, and pouring gate 1 and pouring gate 2 cooperate to form a complete pouring gate, and mold body 1 and mold body 2 are respectively provided with molding cavity 1 and molding cavity 2, and molding cavity 1 and molding cavity 2 cooperate to facilitate product molding; Positioning groove, the mold body 1 is provided with a positioning groove, and the mold body 2 is fixed with a positioning block engaged with the positioning groove; A bending rod, a bending rod is rotatably connected to the mold body one, and an end block is fixed to the end of the bending rod, a clamping hole is opened on the end block, a side plate is fixed to the mold body two, and a fixing rod is fixed between the side plate and the mold body two, a spring is sleeved on the fixing rod, and the fixing rod is slidably connected to a circular hole opened on the vertical plate, a clamping rod extending into the clamping hole is fixed on the vertical plate, and a limiting piece for limiting the clamping rod is provided on the mold body two.

[0007] Preferably, the limiting member includes a slide groove opened on the second mold body, and a slider slidably connected to the slide groove is fixed on the vertical plate, a screw sleeve is threadedly connected to the bent rod, and a round sleeve is threadedly connected to the screw sleeve, the side wall of the round sleeve abuts against the slider, and a control member for controlling the position of the screw sleeve is provided on the second mold body.

[0008] Preferably, the control component includes a protrusion fixedly connected to the second mold body, and a side groove is provided on the protrusion, a fixed disk is fixed on the outer wall of the screw sleeve, and an opening is provided on the fixed disk, and a plurality of openings are distributed at equal angles on the circumference of the fixed disk, a ring is slidably connected to the screw sleeve, a through rod is fixed on the ring, and the through rod passes through the opening and engages with the side groove.

[0009] Preferably, a second spring is sleeved on the screw sleeve, and one end of the second spring abuts against the circular sleeve, and the other end abuts against the collar, and the elastic force of the second spring pushes the collar to move until the collar abuts against the fixed disk.

[0010] Preferably, the side plate is provided with an arc-shaped groove which fits with the outer wall of the end block.

[0011] Preferably, a stop block protrudes from the inner wall of the circular sleeve, and the circular sleeve rotates and moves on the screw sleeve until the stop block abuts against the side wall of the screw sleeve, and the spring 2 is compressed, and at this time the circular sleeve will not block the movement of the slider in the slide groove.

[0012] Preferably, the fixed disk abuts against the protrusion, and the abutment block abuts against the side wall of the screw sleeve. At this time, there is a certain distance between the round sleeve and the fixed disk. The ring can be moved on the screw sleeve by applying force to the handle fixed on the ring until the through rod is disengaged from the side groove and the opening. At this time, the screw sleeve is rotated, causing the screw sleeve and the round sleeve to move on the bent rod together until the screw sleeve is away from the protrusion and the bent rod can rotate normally and detach from the mold body two. At this time, the round sleeve still does not block the movement of the slider in the slide groove.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. The present application connects mold body one with mold body two, and the positioning block on the side wall of mold body two is engaged with the positioning groove provided on mold body one, and then the bent rod can be rotated so that the end block at the end of the bent rod is rotated to fit with the arc groove. During the rotation of the end block, the clamping rod and the side wall of the end block can be slidably connected under the elastic force of spring one, until the clamping hole provided on the end block is aligned with the clamping rod. Under the elastic force of spring one, the clamping rod can be extended into the clamping hole. At this time, mold body one and mold body two are fixed as one. The connection method of mold body one and mold body two is relatively simple and quick, eliminating cumbersome steps, so the staff can quickly get started and operate.

[0014] 2. In the present application, the screw sleeve is fixed to the protrusion under the action of the through rod at this time, that is, the screw sleeve cannot be rotated under force at this time, and the circular sleeve is rotated so that the circular sleeve gradually approaches the slider during rotation until the side wall of the circular sleeve abuts against the slider. At this time, the slider is restricted by the circular sleeve and cannot be moved in the slide groove under force, so the clamping rod cannot be moved under force, so the clamping rod can maintain its own position, and the bent rod cannot be rotated under force and separated from the mold body two, and the connection between the mold body one and the mold body two is more stable.

[0018] Specifically, Figure 1 and Figure 3As shown, the limiter comprises a slide groove 12 provided on the mold body 2, and a slider 15 slidably connected to the slide groove 12 is fixed on the vertical plate 13, a screw sleeve 17 is threadedly connected to the curved rod 5, and a round sleeve 20 is threadedly connected to the screw sleeve 17, and the side wall of the round sleeve 20 abuts against the slider 15, and the mold body 2 is provided with a control member for controlling the position of the screw sleeve 17. The outer wall of the end of the end block 6 is in a smooth arc shape, and the outer wall of the end of the clamping rod 16 is also in a smooth arc shape, so when the end block 6 rotates, the clamping rod 16 can be slidably connected with the outer wall of the end block 6, until the end block 6 fits with the arc groove 9, the clamping rod 16 can extend into the clamping hole 7 under the elastic force of the spring 11, thereby fixing the position of the end block 6, thereby fixing the position of the curved rod 5, and then the mold body 1 and the mold body 2 2 are stably connected as one.

[0019] Specifically, Figure 3 As shown, the control member includes a protrusion 26 fixedly connected to the mold body 2, and a side groove 27 is provided on the protrusion 26, a fixed disk 18 is fixed on the outer wall of the screw sleeve 17, and an opening 19 is provided on the fixed disk 18, and a plurality of openings 19 are distributed at equal angles on the circumference of the fixed disk 18, a collar 23 is slidably connected to the screw sleeve 17, a through rod 24 is fixed to the collar 23, and the through rod 24 penetrates the opening 19 and engages with the side groove 27. A spring 21 is sleeved on the screw sleeve 17, and one end of the spring 21 abuts against the circular sleeve 20, and the other end abuts against the collar 23, and the elastic force of the spring 21 pushes the collar 23 to move until the collar 23 abuts against the fixed disk 18.

[0020] Specifically, Figure 2 As shown, a stopper 22 protrudes from the inner wall of the circular sleeve 20, and the circular sleeve 20 rotates and moves on the screw sleeve 17 until the stopper 22 abuts against the side wall of the screw sleeve 17, and the spring 21 is compressed, and at this time the circular sleeve 20 will not block the movement of the slider 15 in the slide groove 12.

[0021] The fixed plate 18 abuts against the protrusion 26, and the abutment block 22 abuts against the side wall of the screw sleeve 17. At this time, there is a certain distance between the round sleeve 20 and the fixed plate 18. By applying force to the handle 25 fixed on the collar 23, the collar 23 can be moved on the screw sleeve 17 until the through rod 24 is separated from the side groove 27 and the opening 19. At this time, the screw sleeve 17 is rotated, causing the screw sleeve 17 and the round sleeve 20 to move on the bent rod 5 together, until the screw sleeve 17 is away from the protrusion 26, and the bent rod 5 can rotate normally and separate from the mold body 2. At this time, the round sleeve 20 still does not block the movement of the slider 15 in the slide groove 12.

[0022] In summary, when the mold body 1 and the mold body 2 provided in this embodiment are molded together: The mold body 1 is docked with the mold body 2, and the positioning block 4 on the side wall of the mold body 2 is engaged with the positioning groove 3 provided on the mold body 1. Then the bent rod 5 can be rotated so that the end block 6 at the end of the bent rod 5 rotates to fit with the arc groove 9. During the rotation of the end block 6, under the elastic force of the spring 11, the clamping rod 16 can be slidably connected with the side wall of the end block 6 until the clamping hole 7 provided on the end block 6 is aligned with the clamping rod 16. Under the elastic force of the spring 11, the clamping rod 16 can be extended into the clamping hole 7, and at this time, the mold body 1 and the mold body 2 are fixed as one.

[0023] At this time, it is necessary to limit the position of the mold body 1 and the mold body 2 to prevent the mold body 1 and the mold body 2 from accidentally separating. The limiting process is as follows: The collar 23 is pushed by the handle 25 to move until the rod 24 is separated from the hole 19. At this time, the screw sleeve 17 can be rotated so that the fixing plate 18 of the screw sleeve 17 abuts against the protrusion 26 during rotation, and the opening 19 on the fixing plate 18 is aligned with the side groove 27 on the protrusion 26. At this time, the pushing force on the handle 25 can be released, and the collar 23 moves closer to the fixing plate 18 under the elastic force of the spring 21 until the rod 24 on the collar 23 penetrates the opening 19 and engages with the side groove 27.

[0024] At this time, the screw sleeve 17 is fixed to the protrusion 26 under the action of the through rod 24, that is, the screw sleeve 17 cannot be rotated under force at this time. The round sleeve 20 is rotated so that the round sleeve 20 gradually approaches the slider 15 during rotation until the side wall of the round sleeve 20 abuts against the slider 15. At this time, the slider 15 is restricted by the round sleeve 20 and cannot be moved at the slide groove 12 under force, so the clamping rod 16 cannot be moved under force, so the clamping rod 16 can maintain its position, and the bending rod 5 cannot be rotated under force and separated from the mold body 2 2. At this time, the molten glass can be poured into the molding cavity 1 30 and the molding cavity 2 31 through the pouring gate 1 28 and the pouring gate 2 29 until the glass is cooled and formed in the molding cavity 1 30 and the molding cavity 2 31.

[0025] After the glass is formed, it needs to be demoulded: The circular sleeve 20 is rotated so that the circular sleeve 20 gradually moves away from the slider 15 until the abutment block 22 on the circular sleeve 20 abuts against the side wall of the screw sleeve 17. At this time, the movement of the slider 15 will not be affected by the circular sleeve 20, and the collar 23 is pushed to move by the handle 25 until the through rod 24 on the collar 23 is separated from the side groove 27 and the opening 19. At this time, the screw sleeve 17 can be rotated so that the screw sleeve 17 is separated from the protrusion 26 during the rotation, and the circular sleeve 20 will move with the screw sleeve 17, and the circular sleeve 20 will not affect the movement of the slider 15. At this time, the slider 15 can be pushed to move so that the clamping rod 16 is separated from the clamping hole 7 opened on the end block 6. At this time, the bent rod 5 can be rotated, so that the bent rod 5 is separated from the mold body 2 2 during the rotation, and the mold body 1 1 and the mold body 2 2 can be separated by force, that is, the demoulding operation is completed.

[0026] The above description of the embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
