DETAILED DESCRIPTION

[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0031] Example 1: Please refer to Figures 1-10 The sizing cooling die for hose extrusion molding includes a base plate 1 and a hot melt plastic injection assembly 6 arranged on the outside of the base plate 1. A moving assembly 2 is provided on the upper end of the base plate 1. A water tank 3 is fixedly connected to the upper end of the moving assembly 2. A forming die 5 is installed on the moving assembly 2. A water cooling assembly 7 is provided on the forming die 5. A water pump 4 for pumping water in the water tank 3 into the water cooling assembly 7 is fixedly connected to the side wall of the water tank 3 at the upper end of the base plate 1.

[0032] The molding die 5 includes support blocks 51 fixed to both sides of the moving assembly 2. The upper ends of the support blocks 51 are fixed to fixed blocks 52. A cylinder 53 is fixedly connected to the two fixed blocks 52 in a penetrating manner. The cylinder 53 has an open end and a closed structure at the other end. A threaded column 54 is fixedly connected to the inner wall of the other end of the cylinder 53. An internally threaded cylinder 56 is threadedly mounted on the side wall of the threaded column 54. A mounting cylinder 55 is fixedly connected to one end of the internally threaded cylinder 56. The outer wall of the mounting cylinder 55 and the inner wall of the cylinder 53 form a cylindrical area used for injection molding of the hose.

[0033] A heat dissipation assembly 8 is provided on the water cooling assembly 7, and the heat dissipation assembly 8 includes a heat dissipation tube 86 and a heat dissipation groove 87; the heat dissipation tube 86 is installed between the two fixed blocks 52, and a plurality of heat dissipation grooves 87 are opened through the side wall of the heat dissipation tube 86, and the cylinder 53 is located inside the heat dissipation tube 86, and there is a gap between the cylinder 53 and the heat dissipation tube 86.

[0034] During use, the hot-melt plastic is injected into the cylindrical area formed by the outer wall of the mounting tube 55 and the inner wall of the cylinder body 53 through the hot-melt plastic injection assembly 6. This area is used for injection molding of the hose. Then the water pump 4 is turned on to draw the water in the water tank 3 into the water cooling assembly 7. The water will be sprayed on the forming mold 5 to evenly cool the forming mold 5. Since the internal threaded barrel 56 can be removed from the side wall of the threaded column 54, hoses of different sizes can be formed by replacing the internal threaded barrels 56 with different outer diameters. After the hose is formed, the moving assembly 2 is turned on to move the forming mold 5, thereby separating the hot-melt plastic injection assembly 6 and the forming mold 5, making it convenient to remove the hose that has been cooled.

[0035] See also Figure 1 and Figure 3 In this embodiment, the moving assembly 2 includes two guide rails 21 fixed to the upper end of the base plate 1, a moving plate 22 slidingly arranged on the side walls of the two guide rails 21, and a cylinder 23 fixed to the upper end of the base plate 1; the output shaft of the cylinder 23 is fixed to the side wall of the moving plate 22. By arranging the guide rails 21, the moving plate 22 and the cylinder 23 that cooperate with each other, the moving plate 22 can be made to slide stably on the guide rails 21, thereby driving the molding mold 5 to move as a whole, so that the hot melt plastic injection assembly 6 can be quickly separated from the molding mold 5, creating conditions for rapid removal of the hose.

[0036] See also Figure 1 In this embodiment, the water pumping end of the water pump 4 is connected to the water outlet end of the water tank 3 through a pipe, and the water outlet end of the water pump 4 is connected to the water cooling component 7 through a pipe. By setting up the water pump 4 and connecting the water pump 4 with the water tank 3 and the water cooling component 7 through a pipe, the water in the water tank 3 can be stably transported to the water cooling component 7, and the recycling of cooling water can be realized.

[0037] See also Figure 1 and Figure 2 In this embodiment, the hot-melt plastic injection assembly 6 includes a fixed box 61 arranged on the outside of the base plate 1, a fixed cylinder 62 fixedly connected to the fixed box 61 in a through-type manner, an injection tube 63 fixedly connected to the discharge end of the fixed cylinder 62, and an injection head 64 fixedly connected to the discharge end of the injection tube 63. The discharge end of the injection head 64 is penetrated by an injection hole 65, and the discharge end of the injection head 64 abuts against the feed end of the cylinder 53. By providing a hot-melt plastic injection assembly 6 consisting of the fixed box 61, the fixed cylinder 62, the injection tube 63 and the injection head 64, the hot-melt plastic can be injected into the cylindrical area formed by the outer wall of the mounting cylinder 55 and the inner wall of the cylinder 53 through each component in sequence, thereby ensuring the accuracy of the hose injection molding and facilitating the rapid separation of the hot-melt plastic injection assembly 6 from the molding mold 5.

[0038] See also Figure 1 、 Figure 4 and Figure 8In this embodiment, the water cooling assembly 7 includes a vertical block 71 fixed to the upper end of the fixed block 52, a cavity 72 opened in the vertical block 71, a water pipe 73 fixed between the two vertical blocks 71, a plurality of first water outlet holes 74 penetrating the side wall of the water pipe 73, a connecting pipe 75 fixed to the upper ends of the two vertical blocks 71, and a plurality of nozzles 76 fixed to the lower end of the connecting pipe 75; the interior of the water pipe 73 is interconnected with the interior of the cavity 72, the interior of the connecting pipe 75 is interconnected with the interior of the cavity 72, and the water outlet end of the water pump 4 is connected to one of the cavities through a pipe. Inside 72, by setting a water-cooling component 7 consisting of a vertical block 71, a cavity 72, a water pipe 73, a first water outlet 74, a connecting pipe 75 and a nozzle 76, the cooling water can be diverted through the cavity 72, and the forming mold 5 can be sprayed with water from multiple angles through the first water outlet 74 of the water pipe 73 and the nozzle 76 of the connecting pipe 75 to cool the forming mold 5. The water flowing out through the first water outlet 74 will flow to the heat dissipation component 8, and the heat dissipation component 8 can dissipate the heat from the water, and can also introduce the heat-dissipated water into the water tank 3, thereby improving the water-cooling effect of the cooling water.

[0039] See also Figure 1 and Figure 9 In this embodiment, a fixing seat 77 is fixedly connected to the inner wall of the water pipe 73, and a temperature sensor 78 is fixedly connected to the fixing seat 77. A controller is provided on the movable component 2, and the controller and the temperature sensor 78 are electrically connected. By providing the temperature sensor 78 installed on the inner wall of the water pipe 73 and the controller electrically connected thereto, the water temperature in the water pipe 73 can be monitored in real time, and the water pump 4 and other components can be regulated according to the preset temperature range to ensure a stable cooling effect.

[0040] Example 2: Please refer to Figure 4 and Figure 5 , based on Example 1, the present application provides a technical solution: the heat dissipation component 8 also includes a sleeve block 81, a first trough body 82, a second water outlet hole 83, a third water outlet hole 84 and a fourth water outlet hole 85; a first trough body 82 is penetrated at one end of the sleeve block 81, and the inner wall of the first trough body 82 is in contact with the side wall of the water pipe 73. The sleeve block 81 is U-shaped, and a plurality of second water outlet holes 83 are penetrated at the end of the sleeve block 81, and a plurality of fourth water outlet holes 85 are penetrated at the side wall of the sleeve block 81. The second water outlet holes 83 and the first trough body 82 are interconnected, and a plurality of third water outlet holes 84 are penetrated at the inner wall of the first trough body 82. By providing the sleeve block 81 with the first trough body 82 and the plurality of water outlet holes, the heat exchange area between the water flow and the outside world can be increased, and the heat dissipation can be accelerated. The heat dissipation component 8 cooperates with the water cooling component 7 to more efficiently achieve the effect of rapid and uniform cooling of the hose.

[0041] See also Figure 1 、 Figure 5 and Figure 10In this embodiment, a long rod 511 is fixed between the two support blocks 51, and a stopper 512 is fixed to the side wall of the long rod 511. When the sleeve block 81 rotates, the sleeve block 81 is supported by the end of the stopper 512. By providing the stopper 512 on the long rod 511, the rotation position of the sleeve block 81 can be limited, and the relative position of the water outlet holes on the sleeve block 81 and other components can be ensured to be accurate, so that the water in the multiple first water outlet holes 74 on the side wall of the water pipe 73 can flow to the inner wall of the first trough body 82 through the second water outlet holes 83, and then flow out downward through the sleeve block 81.

[0042] Working Principle: First, the discharge end of the external injection molding machine docks with the feed end of the fixed cylinder 62. The hot melt plastic passes through the fixed cylinder 62, the injection tube 63 and the injection head 64, and is then injected into the cylindrical area formed by the outer wall of the mounting cylinder 55 and the inner wall of the cylinder body 53, completing the injection molding of the hose.

[0043] After forming, the water pump 4 is started, and its pumping end is connected to the water outlet end of the water tank 3 through a pipeline, and the water outlet end is connected to the water cooling component 7 through a pipeline, so as to pump the water in the water tank 3 to the water cooling component 7;

[0044] In the water-cooling assembly 7, water first enters a cavity 72 within a vertical block 71 fixed to the upper end of the fixed block 52. Water is then divided through the cavity 72, with one portion flowing out through a water pipe 73 fixed between the two vertical blocks 71 and having a plurality of first water outlet holes 74 formed on its side wall. The other portion is sprayed out through a connecting pipe 75 fixed to the upper ends of the two vertical blocks 71 and a plurality of nozzles 76 at its lower end, thereby spraying water to cool the forming mold 5 from multiple angles.

[0045] During this process, the heat dissipation assembly 8 on the water cooling assembly 7 works in coordination. The heat dissipation cylinder 86 installed between the two fixed blocks 52 has a plurality of heat dissipation grooves 87 on its side wall. The inner wall of the first groove body 82 of the sleeve block 81 fits the side wall of the water pipe 73. The second water outlet hole 83 and the fourth water outlet hole 85 on the side wall of the sleeve block 81 and the third water outlet hole 84 on the inner wall of the first groove body 82 help accelerate heat exchange, allowing the water flow to fully contact the outside world, thereby achieving rapid and uniform cooling of the hose. The water eventually flows into the water tank 3 due to gravity.

[0046] At the same time, the inner wall of the water pipe 73 monitors the water temperature in real time through the temperature sensor 78 fixed to the fixed seat 77, and transmits the data to the controller on the mobile component 2. The controller regulates the water pump 4 and other components according to the preset temperature range to ensure a stable cooling effect.

[0047] If it is necessary to produce hoses of different sizes, since the threaded column 54 is fixed to the inner wall of the barrel 53, the internally threaded barrel 56 is threadedly installed on the side wall of the threaded column 54, and one end of the internally threaded barrel 56 is fixed to the mounting barrel 55, the internally threaded barrel 56 can be removed from the side wall of the threaded column 54 and replaced with an internally threaded barrel 56 of a different outer diameter, thereby changing the size of the cylindrical area between the mounting barrel 55 and the barrel 53 to meet different production requirements;

[0048] After the hose is formed and cooled, the moving assembly 2 is started. The output shaft of the cylinder 23 fixed to the upper end of the base plate 1 pushes the fixed moving plate 22, causing the moving plate 22 to slide stably on the two guide rails 21 fixed to the upper end of the base plate 1, thereby driving the molding die 5 installed on the moving assembly 2 to move as a whole, realizing the separation of the hot melt plastic injection assembly 6 from the molding die 5, creating conditions for the removal of the hose;

[0049] During this process, the stopper 512 on the long rod 511 fixed between the two support blocks 51 limits the rotation position of the sleeve block 81 to prevent the sleeve block 81 from excessive movement, and can help the water droplets in the upper trough fall when the sleeve block 81 swings.
