When the two support rods 5 move upward , it will drive the two ejector rods 6 to move upwards. When the two ejector rods 6 move upwards, it will drive the mounting frame 8 to move upwards. When the mounting frame 8 moves upwards, it will drive the cylindrical plastic mold on the top of the mounting frame 8. Move upwards, here when the ejector rod 6 moves upwards, since the ends of the two retaining rods 17 are set as inclined planes, when the ejector rod 6 moves upwards, the retaining rod 17 will not interfere with the draw-in groove 7 and will push The two clamping rods 17 are close to each other, and in addition, through the elastic reset characteristic of the return spring 19, the two clamping rods 17 can be driven away from each other and reset, so that it can be ensured that the two clamping rods 17 are always clamped into the corresponding two clamping slots 7, so as to limit the decline of the ejector rod 6, and then when the installation frame 8 and the cylindrical plastic mold need to be lowered, the rotating shaft 20 will drive the turntable 21 to rotate, and when the turntable 21 rotates, it will drive The two connecting rods 22 are close to each other. When the two connecting rods 22 are close to each other, they will drive the two sliding bars 23 to be close to each other. When two baffle plates 24 are close to each other, it will drive the two clamping rods 17 to approach each other. When the two clamping rods 17 are close to each other, the clamping limit fit between the clamping rods 17 and the draw-in groove 7 can be released. Through the reverse transmission cooperation between the first motor 2 and the mounting frame 8, the lowering operation of the mounting frame 8 and its top cylindrical plastic mold can be realized.

The above is only a preferred embodiment of the utility model, but the scope of protection of the utility model is not limited thereto. Any equivalent replacement or change of the new technical solution and the concept of the utility model shall be covered by the protection scope of the utility model.
