[0003] After the light tube enters the shaping tooling, the surface of the light tube is usually extruded and shaped through an introduction tube, the inner wall of the introduction tube is sandblasted, and running water is introduced when the light tube enters. The sandblasting on the inner wall of the introduction tube absorbs moisture, so that the light tube can have a certain lubrication and sealing function when moving in the introduction tube.
[0004] However, under the continuous scouring of water flow, the sandblasting on the inner wall of the inlet pipe will gradually fall off, causing the water flow to be unable to attach or unevenly distributed, resulting in vacuum leakage of the shaping tooling and lubrication failure.

[0017] Beneficial effects:
[0018] The utility model provides a light tube shaping tooling comprising a connecting plate, an introduction tube and a water ring; a limiting hole is arranged on the connecting plate, and a mounting groove is arranged outside a hole opening on one side of the limiting hole; the introduction tube is arranged in the mounting groove and one end is inserted into the limiting hole; a water outlet hole is arranged on the inner wall of the water ring, and one end of the water ring is connected and communicated with the other end of the introduction tube; wherein a plurality of water guide grooves are evenly and spacedly arranged on the inner wall of the introduction tube in the circumferential direction, and the water guide grooves extend from the water ring to the introduction tube.
[0019] Specifically, the inner wall of the inlet pipe in the utility model does not use a sandblasting layer to lock and store water, but a water guide groove is set to guide and store water. After the light tube is discharged from the extruder, the water outlet hole on the inner wall of the water ring drains water. Before the light tube enters the inlet pipe from the water ring, the water ring is supplied with water through a water supply device.

[0037] The present invention is further described in detail below through specific embodiments in conjunction with the accompanying drawings.
[0038] See also Figures 1 to 5The light tube shaping tooling provided in this embodiment includes a connecting plate 100, an introduction tube 200 and a water ring 300. A limiting hole 110 is provided on the connecting plate 100, and a mounting groove 120 is provided outside one side opening of the limiting hole 110. The introduction tube 200 is arranged in the mounting groove 120 and one end is inserted into the limiting hole 110. A water outlet hole is provided on the inner wall of the water ring 300, and one end of the water ring 300 is connected and communicated with the other end of the introduction tube 200. Among them, a plurality of water guide grooves 210 are uniformly and spaced apart along the circumferential direction on the inner wall of the introduction tube 200, and the water guide grooves 210 extend from the water ring 300 to the introduction tube 200.
[0039] Specifically, the water guide groove 210 on the inner wall of the introduction pipe 200 in this embodiment can guide and store water. After the light pipe is discharged from the extruder, the water outlet hole on the inner wall of the water ring 300 drains water.
[0040] Before the light pipe enters the introduction pipe 200 from the water ring 300, water is supplied to the water ring 300 through the water supply equipment, and the water flows into the introduction pipe 200 through the water outlet and flows into each water guide groove 210. At this time, observe whether the water flow is uniform, and adjust the water flow rate, increase the water flow rate, so that the water flow can continuously cover the joints between the introduction pipe 200 and the water ring 300, and the joints between the introduction pipe 200 and the connecting plate 100, so as to form a seal between the water guide pipe and the water ring 300, and between the introduction pipe 200 and the connecting plate 100.
[0041] After the adjustment is completed, the light tube enters the introduction pipe 200 from the water ring 300. During the movement of the light tube, the water flow in the water guide groove 210 can play a lubricating role and maintain the sealing of the shaping tooling. There is no need to sandblast in the introduction pipe 200. At the same time, it can also avoid vacuum leakage or lubrication failure of the shaping tooling.
[0042] Furthermore, one end of the introduction tube 200 is the introduction end, and the other end has an extrusion hole. The light tube enters the introduction tube 200 from the introduction end and is discharged from the extrusion hole. Specifically, the extrusion hole of the introduction tube 200 is a pipe mouth at one end located in the limiting hole. By storing water through the water guide groove 210, there will be no sandblasting loss, which can significantly reduce the frequency of regular replacement of the introduction tube 200. By comparison, the sandblasting structure needs to be replaced every 4-6 hours. The introduction tube 200 using the water guide groove 210 structure in this embodiment can be replaced once every two weeks or longer, which not only reduces losses and saves costs, but also reduces replacement and maintenance time, and improves production efficiency.
[0043] In this embodiment, one end of the water guide groove 210 close to the water ring 300 is connected to the water ring 300 .
[0044] The water guide groove 210 extends on the inner wall of the inlet pipe 200. After its end is connected to the water ring 300, when the water ring 300 supplies water, the water flow can directly flow into the water guide groove 210 so that the water flow can fill the water guide groove 210 more quickly. After it is full, water is continued to be injected so that the water flow spreads to the inner wall of the inlet pipe 200.
[0045] Under this structure, the water flowing into the introduction pipe 200 can flow into the water guide groove 210 first, avoiding the water flowing to the inner wall of the introduction pipe 200 first and the water guide groove 210 not being full. After the light tube enters the introduction pipe 200, the water on the inner wall of the introduction pipe 200 is squeezed and flows into the water guide groove 210, resulting in insufficient water for lubrication and sealing during the movement of the light tube.
[0046] In this embodiment, the end of the water guide groove 210 close to the connecting plate 100 is a structure that gradually narrows from the inside to the outside.
[0047] The water in the water guide groove 210 flows in from the end close to the water ring 300 and flows out from the end close to the connecting plate 100. The gradually narrowing structure from the inside to the outside can reduce the flow rate of the water flowing out of the water guide groove 210, so that the water guide groove 210 in the inlet pipe 200 is continuously in an overflowing state, and the inner wall of the water guide pipe can always be covered with water, thereby ensuring the lubrication of the inner wall of the water guide pipe.
[0048] In this embodiment, the depth of the water guide groove 210 at one end close to the connecting plate 100 gradually decreases from the inside to the outside.
[0049] Similarly, in a structure with a gradually shallower depth from the inside to the outside, the volume of the end of the water channel 210 close to the connecting plate 100 is smaller, which can further reduce the flow rate of the water outflowing from the water channel 210, thereby ensuring that the water channel 210 is in an overflowing state, thereby ensuring the lubrication of the inner wall of the water pipe.
[0050] In this embodiment, the inner wall of the introduction pipe 200 gradually widens from an end close to the water ring 300 to an end close to the connection plate 100 .
[0051] See also Figure 1 , Figure 4 The two ends of the introduction pipe 200 in this embodiment are respectively connected to the limiting hole 110 on the connecting plate 100 and the feeding hole on the water ring 300. The introduction pipe 200 is a gradually wide structure, which can make the light pipe move smoothly from the water ring 300 to the connecting plate 100.
[0052] In this embodiment, the light pipe shaping tooling further includes a water injection flange 400. One end of the water injection flange 400 is detachably connected to the connecting plate 100 and is sleeved outside the water ring 300. The water injection flange 400 is provided with a water injection hole 410, and the water injection flange 400 is connected to the water inlet hole of the water ring 300.
[0053] After one end of the water injection flange 400 is connected to the connecting plate 100 , the other end is sleeved outside the water ring 300 , so that the relative positions of the water ring 300 and the connecting plate 100 remain fixed, and water is injected into the water ring 300 to realize the flow water input in the water ring 300 .
[0054] Among them, an injection hole is provided on the side wall of the water injection flange 400 in this embodiment, and a water pipe can be directly connected to the injection hole to achieve water injection.
[0055] In this embodiment, the water ring 300 is connected to the water injection flange 400 by bolts.
[0056] Specifically, a through hole is provided on the water ring 300, and a screw hole is provided on the water injection flange 400. When the water ring 300 is matched and installed with the bolt, the screw hole is connected with the through hole, and the bolt can be screwed into the screw hole after passing through the through hole. The nut at the end of the bolt presses the water ring 300, thereby connecting the water ring 300 with the water injection flange 400.
[0057] In this embodiment, a connection boss 310 is provided at one end of the water ring 300 away from the inlet pipe 200. A mounting hole is provided on the surface of the water injection flange 400. The connection boss 310 is arranged along the circumference of the water ring 300, and a connection hole penetrating the connection boss 310 is provided on the connection boss 310. The bolt is inserted into the connection hole and connected to the mounting hole.
[0058] After the water ring 300 and the water injection flange 400 are matched and installed, the water ring 300 is embedded in the water injection flange 400, and the end of the water ring 300 away from the inlet pipe 200 is located outside the water injection flange 400, and the end face of the connecting boss 310 is abutted and fitted with the end face of the water injection flange 400 away from the water guide member. At this time, the connecting hole on the connecting boss 310 is connected to the mounting hole on the water injection flange 400, and the water ring 300 is connected to the water injection flange 400 by means of bolts passing through the connecting holes and threadedly matching with the mounting holes. The connection structure is simple, very easy to install and disassemble, and very convenient when the inlet pipe 200 needs to be maintained or replaced.
[0059] In this embodiment, the water injection flange 400 is connected to the connecting plate 100 by bolts.
[0060] Specifically, the water injection flange 400 and the connecting plate 100 in this embodiment are also connected by bolts, and the connection is simple, stable, and easy to disassemble and install.
[0061] The light tube production equipment provided in this embodiment includes an extruder, a cooling tank and a light tube shaping tool.
[0062] The extruder has a discharge port, which is connected to the introduction pipe 200 of the light tube shaping tooling. The cooling tank is connected to the limiting hole 110 of the light tube shaping tooling.
[0063] Specifically, after being extruded by the extruder, the light tube enters the water ring 300 of the light tube shaping tooling, and the water guide groove 210 on the inner wall of the introduction tube 200 can guide and store water. The water outlet holes on the inner wall of the water ring 300 drain water, and the water flows into the introduction tube 200 through the water outlet holes and flows into each water guide groove 210. The flow rate of the water flow is increased until the water flow can continuously cover the joints between the introduction tube 200 and the water ring 300, and the joints between the introduction tube 200 and the connecting plate 100, so as to form a seal between the water guide pipe and the water ring 300, and between the introduction tube 200 and the connecting plate 100. The light tube enters the introduction tube 200 from the water ring 300. During the movement of the light tube, the water flow in the water guide groove 210 can play a lubricating role and maintain the sealing of the shaping tooling, thereby avoiding the sandblasting and shedding of the inner wall of the introduction tube 200, resulting in vacuum leakage of the shaping tooling and technical problems of lubrication failure.
[0064] After the light pipe is shaped by the light pipe shaping tool, it is ejected from the light pipe shaping tool through the limiting hole 110 and moved to the cooling tank. After the shaped light pipe is completely cooled to room temperature in the cooling tank, the manufacturing of the light pipe is completed.
[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
