When it is necessary to inject raw materials into the first mold 64 and the second mold 65, the injection molding device 2 is started, and the raw materials are transported to the inside of the rectangular slide 67 through the material hose 63. Under the pressure of the raw materials, the piston 69 moves, and the piston 69 drives the spring 68 to deform. The spring 68 plays a role in resetting the piston 69. The piston 69 drives the rectangular slide 67 to move. The rectangular slide 67 is slidably connected to the inner side of the material channel 66, which plays a role in limiting the direction of the piston 69. The bottom end of the piston 69 is opened in an arc. The piston 69 The bottom end is flush with the inner side of the second mold 65.
