The active cavity 8 is connected to the mold cavity 7 through a movable groove 10. The active cavity 8 and the power cavity 9 are connected to each other. An arc core pulling 11 is slidably connected in each mold cavity 7. When the arc core pulling 11 is located in the mold cavity 7, the front mold core 3 and the rear mold core 4 cooperate with the arc core pulling 11 to introduce raw materials into the mold cavity 7 to directly form a complete laryngoscope blade in the mold cavity 7. Then the arc core pulling 11 is slidably connected in each mold cavity 7. When the core pulling 11 slides vectorially and is received into the active cavity 8 by the movable groove 10, the front mold core 3 and the rear mold core 4 are separated, and the laryngoscope blade is separated from the mold, completing the entire demoulding action, realizing the molding of a complete laryngoscope blade product by the method of arc-shaped core pulling 11 vectorial sliding, reducing the ultrasonic welding steps, and the integrated design realizes the improvement of the appearance hardness, waterproofness and stability of the laryngoscope blade.

A driving assembly for controlling the simultaneous rotation of a plurality of screw rods 1402 is provided on the rear mold frame 2. The driving assembly provides power to drive the plurality of screw rods 1402 to rotate. The rotation of the screw rods 1402 drives the slider 1403 threadably connected to the screw rods 1402 to slide in the control cavity 1401. The control cavity 1401 guides and limits the movement of the slider 1403. The movement of the slider 1403 drives the movement of the push rod 1404 and the slide 13.

[0046] like Figure 2 and Figure 3 and Figure 7 The driving assembly includes a connecting groove which is opened on the rear mold frame 2 and connects to a plurality of control chambers 1401, a transmission shaft 1405 is rotatably connected in the connecting groove, the center line of the transmission shaft 1405 is perpendicular to the center line of the screw rod 1402, a servo motor 1406 for driving the transmission shaft 1405 to rotate is fixed on the rear mold frame 2, each screw rod 1402 is inserted into the connecting groove, an A bevel gear 1407 is coaxially fixed to one end of the screw rod 1402 inserted into the connecting groove, a B bevel gear 1408 which is coaxially nested on the transmission shaft 1405 and fixedly connected to the transmission shaft 1405 is provided, and the A bevel gear 1407 is meshed with the adjacent B bevel gear 1408.

One end of the rocker arm 15 is hingedly connected to the rear mold core 4, and the other end is hingedly connected to the slide 13. The hinge points of the rocker arm 15, the push rod 1404 and the slide 13 coincide with each other. Through the action of the rocker arm 15, the sliding of the slide 13 is limited, thereby ensuring the stability of the movement of the slide 13 and effectively reducing the possibility of shaking of the slide 13.

[0048] like Figure 5The front mold core 3 is provided with an injection assembly 16, and the injection assembly 16 includes an inner material guide cavity 1601 and an outer material guide cavity 1602 which are opened on the front mold core 3 and located on both sides of the mold cavity 7.
