Description

Hot runner structure of injection mold Technical Field The utility model relates to the technical field of injection molds, in particular to a hot runner structure of an injection mold. Background In the injection molding process, the hot runner structure is an important component of the mold, and plays an important role in improving production efficiency and ensuring product quality. The hot runner mold structure is basically the same as the two-plate mold structure and is divided into an adiabatic hot runner system and a heating hot runner system, wherein the adiabatic hot runner is made of a material with low heat conductivity around the runner, is insulated by molten plastic, heats the hot runner, and controls the temperature of the runner through a heating plate on the runner. The hot nozzle is attached with the surface of the flow distribution plate, the temperature controller is used for controlling the melting temperature and plasticizing time of plastic, and when injection molding is carried out, the molten plastic flows into the hot nozzle through the flow distribution plate, thereby reaching the die cavity and carrying out injection molding. The hot runner mold is a plastic material injection molding mold commonly used at present, and has the advantages of saving raw materials, shortening the molding cycle of a workpiece, reducing waste products, improving the product quality, eliminating subsequent procedures, being beneficial to production automation and the like compared with a mold with a cold runner structure. For the tip of the hot runner, the runner outlet and the hot runner are generally horizontally communicated, so that when the runner outlet discharges, injection molding raw materials can be accumulated at the bottom of an inner cavity of a mold, and the injection molding raw materials cannot be uniformly filled in the mold. Disclosure of Invention In order to overcome the defects in the prior art, one of the purposes of the utility model is to provide a hot runner structure of an injection mold. One of the purposes of the utility model is realized by adopting the following technical scheme: The utility model provides a hot runner structure of injection mold, includes the runner cover, the hot runner is installed on the right side of runner cover, the right side of hot runner is equipped with and chews the point, the top of chewing the point has seted up the runner export. Further, the right end plane of the tip is smaller than 0.1mm. Further, a connecting cylinder is arranged between the hot runner and the tip, and the hot runner is connected with the tip through the connecting cylinder. Furthermore, a pouring gate is arranged on the left side of the pouring gate sleeve, and the pouring gate is communicated with the hot runner. Furthermore, the hot runner is communicated with the connecting cylinder, the connecting cylinder is communicated with the runner outlet, and the runner outlet is obliquely arranged. Compared with the prior art, the utility model has the beneficial effects that: According to the hot runner structure of the injection mold, in the use process, the device is arranged on the injection mold, injection molding raw materials enter the pouring gate to reach the inside of the hot runner, and the injection molding raw materials flow out from the runner outlet after passing through the hot runner, and because the runner outlet is obliquely arranged, the injection molding raw materials cannot be accumulated at the bottom of an inner cavity of the mold after flowing out from the runner outlet, so that the injection molding raw materials are uniformly filled in the mold.
