[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-5 As shown, an injection mold for processing a plastic barrel that can be cooled quickly includes a punch 1, a die 2 is movably connected to one side of the punch 1, and a plurality of cooling mechanisms 3 are provided on the other side of the punch 1. The cooling mechanism 3 includes a threaded block 4, a water pipe 5 is fixedly connected to the inner side of the threaded block 4, a guide plate 6 is fixedly connected to the outer side of the water pipe 5, a sealing ring 7 is fixedly connected to a position near the edge of one side of the threaded block 4, one side of the sealing ring 7 is movably connected to a position on the inner side of the punch 1 near the outer side of the water pipe 5, a collecting chamber 8 is fixedly connected to the center position of the other side of the threaded block 4, a hot water outlet 9 is fixedly connected to the top of the collecting chamber 8, a connecting shell 10 is rotatably connected to the outer side of the water pipe 5 near one end, and a cold water outlet 11 is rotatably connected to one side of the connecting shell 10.

[0023] In this embodiment, a spring 12 is movably connected to the inner side of the other end of the connecting shell 10, one end of the spring 12 is movably connected to one end of the water pipe 5, and a rubber ring 13 is movably connected to the inner wall of the other side of the connecting shell 10 near one end of the water pipe 5.

[0024] The spring 12 pushes the connecting shell 10 and the water pipe 5 to move away from each other, thereby squeezing the rubber ring 13 to increase the sealing performance.

[0025] In this embodiment, a circular hole is opened on one side of the rubber ring 13 , and the diameter of the circular hole matches the outer diameter of the water pipe 5 .

[0026] The rubber ring 13 can form a barrier at the connection point between the connection shell 10 and the water pipe 5 to prevent water leakage, so that water can flow into the interior of the mold to cool it down.

[0027] In this embodiment, a plurality of screw holes are symmetrically opened near the middle of the other side of the punch 1, and water holes are opened at the bottom of the screw holes.

[0028] The threaded block 4 is fixed by connecting with the screw hole, and the water pipe 5 can be inserted into the water hole of the punch 1 to inject water.

[0029] In this embodiment, a through hole is opened on one side of the collecting chamber 8, and a hole is opened on one side of the threaded block 4.

[0030] The through hole of the collecting chamber 8 can accommodate the water pipe 5 to pass through, and the water pipe 5 passes through the hole of the threaded block 4 and the through hole of the collecting chamber 8 in sequence.

[0031] In this embodiment, the guide plate 6 has a spiral shape, and the length of the guide plate 6 matches the length of the water pipe 5 inserted into the water hole of the punch 1 .

[0032] The guide plate 6 can guide the return flow trajectory of the water flow, so that the water flow can cool the mold more evenly.

[0033] In this embodiment, a plurality of special-shaped holes are opened on one side of the thread block 4 near the outer side of the hole, and threads are arranged on the outer side of the thread block 4 .

[0034] The water flows into the collecting chamber 8 through the special-shaped holes of the threaded block 4 and is finally discharged through the hot water outlet 9 .

[0035] It should be noted that the utility model is an injection mold for processing plastic barrels that can be cooled quickly. When in use, the mold can be cooled more evenly, and the angle of the cold water port 11 can be adjusted to facilitate access to cooling water from different positions, making the mold installation and use more convenient;

[0036] The specific implementation method is to connect cooling water to the cold water inlet 11 and connect the hot water inlet 9 to the drain pipe 5. Due to the compact structure and limited space of the injection molding equipment, when the cold water inlet 11 is connected to the pipeline, a force can be applied to the cold water inlet 11 to make it rotate around the connection with the connecting shell 10, so that the cold water inlet 11 can be conveniently connected to the pipeline from above or below, and the connecting shell 10 can be rotated around the connection with the water pipe 5 by rotating it;

[0037] When the connecting shell 10 rotates, the cold water inlet 11 will be driven to rotate together, so that the cold water inlet 11 faces different directions, so that it can be connected with pipes in different directions. When the traditional method of connecting pipes is used, in order to make the pipes connect with the mold, the pipes need to be bent for connection. By providing a rotatable cold water inlet 11, pipes from all directions can be connected, and the water pipe 5 can be avoided from being bent, so as to prevent the cooling water supply from being affected.

[0038] The cooling water is injected into the water pipe 5 through the cold water inlet 11, and enters the water hole of the punch 1 through the water pipe 5. The cooling water refluxes in the water hole of the punch 1 and enters the collecting chamber 8 through the special-shaped hole of the threaded block 4, and is discharged through the hot water inlet 9. In the process of water reflux, it will be guided by the guide plate 6 and move around the water pipe 5 in a spiral path. While the water flow moves in a spiral, the cooling water after heat exchange with the mold and the cooling water that has not been heat exchanged are mixed to make the water temperature uniform, thereby cooling the mold more evenly to avoid the quality of the plastic barrel being affected by uneven heat during cooling and molding.

[0039] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
