Injection molding devices are widely used in the fields of household appliances, automobiles, electronic products, medical equipment, toy products and electrical accessories. The injection molding device is composed of a liquid injection structure and a device mold base. The liquid injection structure is provided with a liquid injection gate, and the device mold base is provided with a connected installation groove and a mold cavity. The liquid injection structure is provided in the installation groove and connected to the device mold base, and the liquid injection gate is connected to the mold cavity.

[0003] In the prior art, the traditional liquid injection structure includes a connected structural body and a liquid inlet component, the liquid inlet component is used to introduce the glue liquid, the structural body is provided with a connecting flow channel, the liquid inlet component is connected with the connecting flow channel, so that the glue liquid enters the connecting flow channel through the liquid inlet component, and the inner wall of the connecting flow channel is provided with a liquid injection gate for communicating with the mold cavity, so that the glue liquid enters the mold cavity along the liquid injection gate to fill the mold cavity and complete the liquid injection process, such as the Chinese patent No. CN201310317413.8.

[0004] However, since the glue enters the cavity along the injection gate to fill the cavity, the number of injection gates is single, that is, the glue enters the cavity along a single injection gate, so that the glue is more concentrated when each injection gate is used to inject glue into the cavity, so that the amount of glue injected into the cavity by each injection gate is larger, so that the injection stress of each injection gate for injecting glue into the cavity is larger, that is, the injection stress of the injection structure for injecting glue into the cavity is larger, so that the speed of the injection structure for injecting glue is higher, so that the flow speed of the glue in the cavity is faster, resulting in the glue on the surface of the product near the injection gate is more likely to be misplaced, so that the outer surface of the product is more likely to leave gate marks, so that the outer surface of the product is more likely to have molding defects, which is not convenient for the molding process of the product, and thus the molding process of the product is less convenient.
