[0029] The protective mechanism includes a connecting pipe 2, which is sleeved on the surface of the water hose 15. A rubber sleeve 21 is fixedly connected to the surface of the connecting pipe 2. A mounting pipe 22 is fixedly connected to the surface of the injection molding table 11. A fixing bin 23 is fixedly connected to the surface of the mounting pipe 22. A supporting spring 24 and a limit plate 25 are movably connected to the inner surface of the fixing bin 23. A plug block 26 is fixedly connected to the surface of the limit plate 25. A first plug hole 27 is provided on the surface of the connecting pipe 2. A second plug hole 28 is provided on the surface of the mounting pipe 22. Under the action of the connecting pipe 2, the bending position of the water hose 15 can be kept away from the surface of the injection molding table 11. The connecting pipe 2 covers the connection between the water hose 15 and the injection molding table 11, so as to protect the connection.
[0030] Furthermore, the connecting pipe 2 is plugged into the inner surface of the mounting pipe 22, the cross-section of the rubber sleeve 21 is arc-shaped, the inner diameter of the mounting pipe 22 is the same as the outer diameter of the connecting pipe 2, and two groups of fixing bins 23 are provided. The two groups of fixing bins 23 are installed on both sides of the mounting pipe 22. The rubber sleeve 21 is made of soft rubber and is arranged at the edge of the connecting pipe 2, which can prevent the water supply hose 15 from being scratched by friction with the connecting pipe 2. The installation effect of the connecting pipe 2 can be achieved through the mounting pipe 22, and at the same time, the installation effect of the support spring 24, the limit plate 25 and the plug 26 can be achieved under the action of the fixing bin 23.
[0031] Furthermore, two groups of support springs 24 are provided, and the two groups of support springs 24 are installed on both sides of the fixed bin 23. One end of the support spring 24 is fixedly connected to the inner surface of the fixed bin 23, and the other end of the support spring 24 is fixedly connected to the surface of the limit plate 25. The limit plate 25 is abutted against the outer surface of the mounting tube 22. Under the action of the support spring 24, a supporting force can be applied to the surface of the limit plate 25, and the limit plate 25 and the plug block 26 are pushed to always have a tendency to move toward the inside of the mounting tube 22. The size of the limit plate 25 is larger than the size of the second insertion hole 28. The limit plate 25 can limit the plug block 26 to prevent the plug block 26 from moving out of the second insertion hole 28. At the same time, one side of the limit plate 25 is rectangular and the other side is arc-shaped and the diameter is the same as the outer diameter of the mounting tube 22.
[0032] Furthermore, the plug block 26 is plugged and connected to the surfaces of the first socket 27 and the second socket 28. There are two groups of the first socket 27 and the second socket 28.

When the plug block 26 is plugged and connected with the first socket 27 and the second socket 28, the connecting pipe 2 installed in the mounting pipe 22 can be limited.
[0033] Furthermore, a control mechanism is provided on the surface of the water hose 15, and the control mechanism includes a spherical bin 3, which is fixedly connected to the surface of the water hose 15, and a connecting hole 31 and a through hole 32 are provided on the surface of the spherical bin 3. An annular plate 33 is movably connected to the inner surface of the spherical bin 3, and a connecting rod 34 is fixedly connected to the surface of the annular plate 33. A rotating groove 35 is provided inside the spherical bin 3, and a sealing ring 36 and a handle 37 are fixedly connected to the surface of the connecting rod 34. By installing the spherical bin 3 on the surface of the water hose 15 where cooling water flows into the cooling water circulation machine 13, the time that the cooling water stays in the water flow trough 12 can be controlled, thereby improving the utilization rate of the cooling water.
[0034] Furthermore, two groups of connecting holes 31 are provided, and the two groups of connecting holes 31 are opened on both sides of the spherical warehouse 3. The diameter of the connecting hole 31 is the same as the inner diameter of the water hose 15, the diameter of the through hole 32 is the same as the diameter of the connecting rod 34, and the outer diameter of the annular plate 33 is the same as the inner diameter of the spherical warehouse 3. The spherical warehouse 3 and the water hose 15 can be communicated through the connecting hole 31, and the installation effect of the connecting rod 34 can be achieved under the action of the through hole 32. The inner and outer surfaces of the annular plate 33 are spherical, and the width of the annular plate 33 is greater than the diameter of the connecting hole 31, which can completely cover it.

The connecting rod 34 is rotatably connected to the surface of the through hole 32. The size of the rotating groove 35 is the same as the size of the sealing ring 36. The sealing ring 36 is rotatably connected to the surface of the rotating groove 35. Under the connection between the connecting rod 34 and the annular plate 33 and the handle 37, the connection between the handle 37 and the annular plate 33 can be realized and the two can rotate around the connecting rod 34. Under the connection between the rotating groove 35 and the sealing ring 36, the connection between the through hole 32 and the connecting rod 34 can be prevented from water seepage.
[0036] Working principle: before installing the cooling and molding device, first put the connecting pipe 2 on the surface of the water hose 15 from the side where the rubber sleeve 21 is installed, and connect the water hose 15 and the injection molding table 11, and then align the connecting pipe 2 with the inner side of the mounting tube 22 and insert it therein. At this time, the plug blocks 26 on both sides are squeezed by the connecting pipe 2 and move through the second plug hole 28 into the fixed bin 23 to which they are connected, so as to drive the limit plate 25 to slide on the surface of the fixed bin 23, the support spring 24 is in a compressed state, and the limit plate 25 cancels the abutment state with the outer side of the mounting tube 22, and then the connecting pipe 2 is rotated and adjusted to slide on the inner side of the mounting tube 22. When the hole positions of the first plug hole 27 and the second plug hole 28 are aligned, the plug block 26 is inserted into the surface of the first plug hole 27 under the action of the supporting force applied by the support spring 24, and the limit plate 25 is abutted against the mounting tube 22 again to complete the installation of the connecting pipe 2, and then the water hose 15 is placed along the connecting pipe 2 and the rubber sleeve 21.
[0037] When manufacturing different refrigerator plastic injection moldings, the amount of cooling water required for cooling is determined according to their sizes. When the injection molding requires more cooling water, the handle 37 can be rotated around the connecting rod 34 and drive the annular plate 33 to rotate in the spherical bin 3, the connecting rod 34 rotates on the surface of the through hole 32, and the sealing ring 36 rotates in the rotating groove 35, so that the gap formed by the connecting hole 31 and the annular plate 33 can be gradually enlarged, and the speed of cooling water flowing from the water flow groove 12 is increased, so that the cooling water can be replaced faster for use. When the injection molding requires less cooling water, the handle 37 can be rotated to gradually reduce the gap between the annular plate 33 and the connecting hole 31 to increase the utilization efficiency of the cooling water.
[0038] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
