[0033] As a further implementation of the present scheme, the first mold assembly 3 is slidably connected with the second fixed template assembly 4, the structure of the second fixed template assembly 4 is the same as that of the first fixed template assembly 2, the second fixed template assembly 4 is mounted with a second mold assembly 5 on one side, and the mold body 31 is provided with an injection slot 33 and an injection nozzle 34 fixedly connected inside. Through the above setting, the installation and replacement of the mold are more flexible and convenient, and the injection slot 33 and the injection nozzle 34 provide a good channel for injection and cooling, ensuring the quality and cooling efficiency of the injection part;

[0036] Through the above setting, the overflow of cooling water can be effectively prevented, while ensuring the smooth flow of cooling water, improving the sealing performance and cooling effect of the cooling system, and ensuring the rapid cooling of the mold after injection.

[0037] Workflow: When installing the replacement injection mold, first align the folding channel 35 on the inner side of the mold body 31 with the limiting cylinder 28. Then, insert the mold body 31 into the outer side of the limiting cylinder 28 through the folding channel 35. At this time, the sealing ring 29 is in contact with the inner side of the folding channel 35. The sealing ring 29 seals the space between the limiting cylinder 28 and the mold body 31 to prevent cooling water from overflowing. After the right side of the mold body 31 is in contact with the left side of the mold plate body 21, start the servo motor 22 to drive the double threaded rod 23 to rotate. The double threaded rod 23 drives the two spirally connected slope plates 24 on the outside to move simultaneously toward the mold body 31. The slope plates 24 are slidably connected to the outside of the guide rod 27, which limits the movement of the guide rod 27. When the slope plate 24 contacts the slope groove 32, due to the shape of the slope plate 24 and the slope groove 32, the mold body 31 will be tightly attached to the template body 21, which can improve the stability of the fixation between the mold body 31 and the template body 21. Based on the same principle, the second mold assembly 5 is installed on one side of the second fixed template assembly 4.

[0038] When the infusion component housing is injection molded, the injection groove 33 is connected to the injection molding machine, the two limiting cylinders 28 at the rear end are connected to the outlet of the cooling water pipe, and the two limiting cylinders 28 at the front end are connected to the inlet of the cooling water pipe. The hydraulic rod 12 is activated to drive the template body 21 to move, and the slide 25 slides on the outside of the guide post 13, which can ensure that the second mold assembly 5 and the template body 21 are precisely aligned. When the injection groove 33 of the second mold assembly 5 is aligned with the injection groove 33 of the mold body 31, the injection molding machine and the injection nozzle 34 are used to inject the injection groove 33. After the injection is completed, the injection groove 33 is cooled. The cold water enters the rear folding channel 35 and the cooling tank 36 from the inside of the two limiting cylinders 28 at the rear end, and then flows out through the front folding channel 35 and the limiting cylinder 28, thereby achieving the cooling effect.

[0039] Based on the above principles, when changing different types of molds, the device can ensure that the mold is aligned with the cooling system and with each other, improving the compatibility of the device and reducing the difficulty of installation, thus ensuring the quality of subsequent injection molding.
