DETAILED DESCRIPTION

[0029] In order to make the purpose, technical scheme and advantages of the utility model more clearly, the following will be further described in detail in combination with the drawings and examples.

[0030] In one embodiment, as shown in Figures 1-4 A multi-layer nested conformal cooling water channel structure, comprising two fixed water pipes 4 symmetrically arranged at one end of a lower mold 1, an upper mold 9 arranged at the top end of the lower mold 1, a plurality of connecting water pipes 3 vertically and equidistantly fixedly connected to the outer wall of each fixed water pipe 4, the plurality of connecting water pipes 3 being fixedly connected to the lower mold 1, a water inlet pipe 8 installed at the top end of one fixed water pipe 4, a filter cartridge 7 arranged at the end of the water inlet pipe 8 away from the one fixed water pipe 4, two connecting end heads 5 symmetrically formed on the outer wall of the filter cartridge 7, a butt end head 6 sleeved on the outer wall of each connecting end head 5, the connecting end head 5 and the butt end head 6 being threadedly connected, one butt end head 6 being fixedly connected to the water inlet pipe 8, the other butt end head 6 being fixedly connected to the output end of a water pump through a first water delivery pipe away from the filter cartridge 7, the input end of the water pump being fixedly connected to a water tank through a second water delivery pipe, the bottom end of the other fixed water pipe 4 being fixedly connected to a drain pipe fixedly connected to the water tank, and a plugging mechanism arranged on the butt end head 6 for plugging the port of the butt end head 6;

[0031] The plugging mechanism comprises a moving assembly arranged on the butt end head 6.

[0032] The moving assembly comprises a moving slide cylinder 205 arranged inside the butt end head 6, a plurality of drain holes 202 equidistantly formed on the outer wall of the moving slide cylinder 205, the plurality of drain holes 202 being mutually penetrated with the inner cavity of the moving slide cylinder 205, a limiting push ring 204 integrally formed at one end of the moving slide cylinder 205, and the limiting push ring 204 being in contact with the outer wall of the connecting end head 5.

[0033] A limiting assembly is arranged on the moving slide cylinder 205.

[0034] In this embodiment, it is particularly noted that the lower mold 1 is provided with a multi-layer nested conformal cooling water channel, the connecting position between the lower mold 1 and the plurality of connecting water pipes 3 is provided with a water inlet and a drain hole mutually penetrated with the multi-layer nested conformal cooling water channel, and the inside of the filter cartridge 7 is provided with activated carbon for filtering the cooling water.

[0035] In use, the water pump is started to deliver the cooling water in the water tank to the inner cavity of the filter cartridge 7 through the first water delivery pipe and the second water delivery pipe. At this time, the impurities in the cooling water can be filtered by the activated carbon in the inner cavity of the filter cartridge 7. Then the filter cartridge 7 delivers the cooling water to the inner cavities of the plurality of connecting water pipes 3 through the water inlet pipe 8 and the fixed water pipe 4. At this time, the plurality of connecting water pipes 3 can effectively improve the cooling efficiency of the lower mold 1. Then the cooling water in the inner cavity of the lower mold 1 is delivered to the inner cavity of the other fixed water pipe 4 through the plurality of connecting water pipes 3. Then the other fixed water pipe 4 delivers the cooling water to the water tank through the drain pipe, so as to recycle the cooling water.

[0036] When the activated carbon in the inner cavity of the filter cartridge 7 is used for a long time and the filtering effect is poor, the filter cartridge 7 is rotated, and the connecting end head 5 is driven by the filter cartridge 7 to move along the inner wall of the mating end head 6 through the threaded connection with the mating end head 6 until the connecting end head 5 and the mating end head 6 are separated from each other, so as to conveniently replace the filter cartridge 7.

[0037] In this process, the blocking mechanism can drive the moving slide cylinder 205 to move synchronously with the movement of the connecting end head 5 until the plurality of drain holes 202 are moved between the fixed sleeve ring 207 and the limiting push ring 204. At this time, the port of the mating end head 6 can be automatically blocked, so as to realize the purpose of replacing the filter cartridge 7 without stopping the machine, effectively avoiding the situation that a large amount of cooling water leaks during the replacement of the filter cartridge 7, and further improving the cooling efficiency of the injection mold.

[0038] In one embodiment, as shown in Figures 2-4 The limiting assembly is a fixed sleeve ring 207 which is slidably sleeved on the outer wall of the moving slide cylinder 205. The fixed sleeve ring 207 is fixedly connected with the mating end head 6. The fixed sleeve ring 207 is located between the drain hole 202 and the limiting push ring 204. The inner wall of the fixed sleeve ring 207 is provided with a sealing rubber ring which is in contact with the outer wall of the moving slide cylinder 205. The sealing rubber ring is used to seal the gap between the fixed sleeve ring 207 and the moving slide cylinder 205.

[0039] The moving slide cylinder 205 is provided with a moving assembly.

[0040] The moving assembly comprises a plurality of connecting push plates 201 which are fixedly connected on the outer wall of the moving slide cylinder 205 at equal intervals. The plurality of connecting push plates 201 are located at one end of the drain hole 202 away from the fixed sleeve ring 207.

[0041] The connecting push plate 201 is provided with a sliding assembly.

[0042] The sliding component is a limiting slide rod 208 fixedly connected to one end of the connecting push plate 201. The limiting slide rod 208 passes through the fixed collar 207 and is fixedly connected to the limiting push ring 204. The limiting slide rod 208 is slidably connected to the fixed collar 207. Through the cooperation of the limiting component, the moving component and the sliding component, the port of the docking end 6 can be sealed when the filter cartridge 7 is disassembled.

[0043] A reset component is provided on the limit slide bar 208;

[0044] In one embodiment, such as Figures 2-3 As shown, the reset component is a spring 203 sleeved on the outer wall of the limiting slide bar 208. One end of the spring 203 is in contact with the outer wall of the limiting push ring 204, and the other end of the spring 203 is in contact with the outer wall of the fixing collar 207.

[0045] A sealing assembly is provided on spring 203;

[0046] The sealing component is a telescopic sleeve 206 fitted onto the outer wall of the spring 203. One end of the telescopic sleeve 206 is fixedly connected to the limiting push ring 204, and the other end of the telescopic sleeve 206 is fixedly connected to the fixing ring 207. Through the cooperation of the reset component and the sealing component, the limiting push ring 204 can be pushed to automatically move as the connecting end 5 moves.

[0047] The above embodiment discloses a multi-layer nested conformal cooling water circuit structure. In use, the water pump is started and the cooling water in the water tank is delivered to the inner cavity of the filter cylinder 7 through the first water supply pipe and the second water supply pipe. At this time, the activated carbon in the inner cavity of the filter cylinder 7 can filter the impurities in the cooling water. Then, the filter cylinder 7 delivers the cooling water to the inner cavities of multiple connecting water pipes 3 through the water inlet pipe 8 and the fixed water pipe 4. At this time, the multiple connecting water pipes 3 can effectively improve the cooling efficiency of the lower mold 1. Then, the cooling water in the inner cavity of the lower mold 1 is delivered to the inner cavity of another fixed water pipe 4 through the multiple connecting water pipes 3. Then, the other fixed water pipe 4 delivers the cooling water to the water tank through the drain pipe to facilitate the recycling of the cooling water.

[0048] When the activated carbon in the inner cavity of the filter cartridge 7 becomes ineffective after prolonged use, the filter cartridge 7 is rotated. At the same time, the connecting end 5, driven by the filter cartridge 7, moves along the inner wall of the docking end 6 through the threaded connection with the docking end 6 until the connecting end 5 and the docking end 6 separate, so as to facilitate the easy replacement of the filter cartridge 7.

[0049] In the process, the spring 203 pushes the limiting push ring 204 tightly with the outer wall of the connecting end head 5 through rebound, so that the limiting push ring 204 can be displaced synchronously with the movement of the connecting end head 5, and the telescopic sleeve 206 is stretched under the driving of the limiting push ring 204, at this time, the moving slide cylinder 205 is driven by the limiting push ring 204, and the limiting slide rod 208 is pushed along the inner wall of the fixed sleeve ring 207 through the connecting push plate 201, and the plurality of drainage holes 202 are synchronously moved under the driving of the moving slide cylinder 205, when the plurality of drainage holes 202 are moved between the fixed sleeve ring 207 and the limiting push ring 204, the port of the butt joint end head 6 can be automatically blocked at this time, so as to realize the purpose of replacing the filter cartridge 7 without stopping, effectively avoiding the situation that a large amount of cooling water leaks in the process of replacing the filter cartridge 7, and further improving the cooling efficiency of the injection mold.
