[0023] Please see Figures 1 to 4This utility model provides an embodiment of a 3D-printed mold insert, comprising an insert body 1, which is made by 3D printing. An inlet 10 and an outlet 11 are provided on the outer edge of the insert body 1. A spiral flow channel 12 is formed in the insert body 1, and the first and last ends of the spiral flow channel 12 are connected to the inlet 10 and the outlet 11, respectively. The inlet 10 and the outlet 11 are respectively connected to an inlet pipe 7 and an outlet pipe 6. Cooling medium enters the inlet 10 through the inlet pipe 7, then enters the spiral flow channel 12 through the inlet 10 to cool the mold, and then exits through the outlet 11 and the outlet pipe 6, thus circulating the cooling process. A threaded interface 8 is provided at the upper end of both the inlet 10 and the outlet 11. The bottom of the inlet pipe 7 and the outlet pipe 6 are fixedly connected to a connector 14, which is screwed to a screw interface 8. The screw interface 8 has an internal thread, and the connector 14 has an external thread. A sealing gasket 13 is installed between the bottom of the connector 14 and the insert body 1. A socket 15 is provided on the outside of the connector 14. A receiving groove 16 is opened on the upper side of the insert body 1. When the connector 14 and the screw interface 8 are connected, the socket 15 is inserted into the receiving groove 16. A set screw 17 is screwed to the outside of the insert body 1. The end of the set screw 17 presses against the socket 15 to prevent the set screw 17 from directly pressing against the connector 14 and damaging the connection of the outer wall of the connector 14. At the same time, the outer wall of the socket 15 is provided with anti-slip texture, which, together with the set screw 17 pressing against the socket 15, can greatly improve stability.

[0024] The outer wall of the insert body 1 is integrally formed with a fixing platform 2, and the fixing platform 2 is evenly provided with mounting holes 3 for installation and fixing in the mold.

[0025] The fixed platform 2 has a positioning surface 4 on its side, and the main body of the insert 1 has a positioning groove 5 on its upper side.

[0026] The positioning surface 4 and the positioning groove 5 are misaligned. There is one positioning surface 4 and one or two positioning grooves 5, which are used for positioning and installation. Misalignment occurs during installation.

[0027] The bottom of the screw interface 8 is provided with a sealing groove 9, and the sealing gasket 13 is located in the sealing groove 9. The thickness of the sealing gasket 13 is greater than the depth of the sealing groove 9. The sealing groove 9 has an annular structure, which allows the connector 14 to effectively compress the sealing gasket 13.

[0028] A hexagonal force-bearing block 18 is fixedly connected to the upper end of the connector 14 to facilitate the rotation of the connector 14.

[0029] The lower side of the socket 15 is ring-shaped, and when the socket 15 is inserted into the receiving groove 16, there is a gap between the socket 15 and the receiving groove 16.

[0030] Working principle: In this invention, threaded interfaces 8 are provided at the upper ends of both the inlet 10 and the outlet 11. Connectors 14 are then provided at the bottom of the inlet pipe 7 and the outlet pipe 6. With the sealing gasket 13, when the connector 14 is installed in the threaded interface 8, it can compress the sealing gasket 13, thereby forming a seal. The connection is convenient. When the connector 14 and the threaded interface 8 are connected, the socket 15 is inserted into the receiving groove 16. By rotating the set screw 17, the set screw 17 can compress the socket 15, thereby greatly improving the stability after connection and enabling long-term stable fixation. This prevents the connector 14 from loosening, which would affect the sealing effect.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
