The transmission assembly 3 also includes a transmission groove 302, which is opened on one side of the transmission frame 301. A connecting groove 303 is opened on the top of the transmission frame 301, and the interior of the connecting groove 303 is fixedly connected to the interior of the transmission groove 302. The connecting groove 303 is slidably connected to the interior of the transmission groove 302 and the outer side of the limit block 306. A limit block is provided inside the connecting groove 303. The positioning groove 304 has a sealing gasket 305 fixedly connected inside. The inside of the sealing gasket 305 is movably connected to the outside of the positioning block 306. Through the sliding connection between the positioning block 306 and the connecting groove 303, the transmission frame 301 can perform positioning and guiding work on the positioning block 306. The installed sealing gasket 305 can seal the gap between the positioning block 306 and the connecting groove 303, so that the rotating block 204 can push the positioning block 306 downward through the connecting column 202. The downward movement of the positioning block 306 can reduce the transmission space inside the transmission groove 302, thereby reducing the speed and flow rate of the injection molding material.

When using the device, the mold 2 10 can be pushed to the other side of the mold 1, so that the mold groove 1 9 and the mold groove 2 11 can be merged. Then the injection molding machine can be started, so that the injection molding machine can transfer the injection plastic through the injection ring 7 to the inside of the transfer groove 302, so that the transfer groove 302 can transfer the injection plastic to the inside of the injection port 8, so that the injection plastic can be injected into the mold groove 1 9 and the mold groove 2 11 through the injection port 8.

[0029] The usage and advantages of this utility model: The injection mold with controllable material flow rate operates as follows:

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, when using this device, mold 2 10 can first be pushed to the other side of mold 1 1, so that mold slot 1 9 and mold slot 2 11 can be merged. Then, the injection molding machine can be started, so that the injection molding machine can transfer the injection plastic through the injection ring 7 to the inside of the transfer groove 302, so that the transfer groove 302 can transfer the injection plastic to the inside of the injection port 8, so that the injection plastic can be injected into mold slot 1 9 and mold slot 2 11 through the injection port 8.

Simultaneously, through the sliding connection between the limiting block 306 and the connecting groove 303, the transmission frame 301 can limit and guide the limiting block 306. Furthermore, through the installed sealing gasket 305, the gap between the limiting block 306 and the connecting groove 303 can be sealed, allowing the rotating block 204 to push the limiting block 306 downward through the connecting column 202. The downward movement of the limiting block 306 reduces the transmission space inside the transmission groove 302, thereby reducing the speed and flow rate of the injection molding material. Moreover, by observing the height difference between the scale 6 and the handle 206, the size of the internal space of the transmission groove 302 can be controlled, thus enabling precise control of the injection molding speed and flow rate.
