[0026] In this embodiment, the rotating mold 23 is further provided with a connecting joint 233 between the sub-mold groove I 231 and the sub-mold groove II 232. The connecting joint 233 has slots on its upper and lower sides, such as... Figure 2 As shown, the connector 233 protrudes outward from the rotating mold 23; the double-cavity mold 32 has a mating groove 323 corresponding to the connector 233 between the first mold cavity 321 and the second mold cavity 322. The upper and lower sides of the mating groove 323 are rotatably mounted with claws 3231. The claws 3231 are connected to the inner wall of the mating groove 323 through the connecting spring 3232. When the rotating mold 23 and the double-cavity mold 32 are closed, the connector 233 is inserted into the mating groove 323, and the claws 3231 are inserted into the slot of the connector 233, thereby improving the stability when the rotating mold 23 and the double-cavity mold 32 are closed and preventing the rotating mold 23 from detaching from the double-cavity mold 32. After the toothbrush injection molding is completed, the rotating mold 23 and the double-cavity mold 32 are separated. The slot of the connector 233 squeezes the claws 3231, causing the connecting spring 3232 to retract, and the claws 3231 separate from the slot of the connector 233.
