This utility model relates to a manifold core structure for a plasticizing device, which includes a manifold core body and a confluence structure arranged inside the manifold core body. The manifold core body is provided with a feed inlet and a discharge port, a fluid channel is formed between the feed inlet and the discharge port, and the confluence structure is located in the fluid channel. The confluence structure consists of a flow guide column, a positioning ring and a throttling and pressurizing hole. The utility model has a scientific and reasonable structural design and is easy to implement; the confluence structure is added in the fluid channel of the manifold core to throttle and perform secondary mixing on the raw materials flowing out of the twin-screw extruder, so that the raw materials are fully mixed and the mixing capacity of the molten materials is improved. This avoids particles on the product surface caused by uneven mixing after the subsequent forming of sealing strips, and can effectively ensure the quality of finished products.
