Description
Technical Field
[0001] The utility model belongs to the technical field of hot runner, and particularly relates to a split manifold plate for easily solidifying materials. Background Art
[0002] Common injection molding materials include thermosetting materials and thermoplastic materials. Plastic is a thermoplastic material. As the name implies, when the temperature exceeds the melting point, the material will melt, and then the material is injected into the mold cavity under high pressure and cooled to form. There is essentially no difference between granular plastic particles and the formed products. Rubber can be said to be thermosetting, without a melting point, only a burning point. It burns when the temperature exceeds a certain value. The process of rubber molding is a vulcanization process, and the internal molecular structure has changed. Generally, it can be understood that many short-chain structures are cross-linked into complex multi-chain structures through cross-linking. The essence has changed. Rubber injection molding uses high pressure to inject semi-finished mixed rubber (in solid or liquid state) into the mold cavity, and then vulcanizes and forms at a certain temperature for a certain period of time. The mold for plastic molding is cold, while the mold for rubber molding is hot. These two differences are very significant.
[0003] This application is a targeted research and development for rubber materials. The molding temperature is about 180°. If the temperature is too low, it cannot be completely melted. If the temperature is too high, such as exceeding 200°, the higher the temperature, the faster the internal molecular structure flows, and small molecules quickly cross-link into large molecules, and the faster the cross-linking, the faster the solidification and molding. Therefore, this application designs a manifold plate that is easy to clean the solidified materials. Summary of the Utility Model
[0004] Aiming at the deficiencies of the existing technology, the utility model provides a split manifold plate, which is easy to disassemble and assemble and convenient for cleaning solidified materials.

[0006] Furthermore, upper pads are arranged on the top surface of the upper manifold plate, and lower pads are arranged on the bottom surface of the lower manifold plate.
[0007] Further, a sealing ring groove is provided on the outer side of the outer circle of the lower flow dividing channel on the lower flow dividing plate, and a sealing copper wire is arranged in the sealing ring groove.
[0008] Further, the diameter of the injection nozzle channel gradually increases from the A end to the B end to form a conical shape; the A end is the glue inlet, and the B end is the glue outlet.
[0009] Further, an upper vertical channel communicating with the flow dividing plate channel is provided on the upper flow dividing plate, and the upper vertical channel is engaged with the B end of the injection nozzle channel.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0015] The flow dividing plate is designed to be split type, including two parts of an upper flow dividing plate and a lower flow dividing plate. The flow channel does not need to be drilled with a gun drill, and the plug flow channel is smooth without dead angles. A sealing copper wire is designed around the flow channel for sealing to prevent the overflow of the rubber material. The flow channels inside the injection nozzle and the hot nozzle are designed into a conical shape, which is convenient for clearing the cured rubber material. The flow dividing plate can be disassembled at any time to take out the cured rubber material, and the internal flow channel is smooth. The heating is balanced, it is easy to keep the temperature constant, and the curing rate is reduced. When the thermosetting material rubber is injection molded, first, the temperature is constant and it is not easy to cure; second, after the rubber material is cured, the hot runner is easy to disassemble without dead angles and easy to clean the glue, which improves the molding quality and injection molding efficiency and reduces the generation of waste rubber material.

The guide post fixing screw 11 is mounted and fixed from the bottom surface to the top surface of the lower flow divider plate 2 in a square shape; the commonly used flow divider plate heating wire, thermocouple, center pad, etc. are sequentially mounted on the flow divider plate in the existing manner; the injection nozzle 8 is further provided with an axial positioning surface, which cooperates with the positioning ring surface; after the hot runner is assembled, the assembled system is mounted and fixed on the template by the flow divider plate fixing screw I 5, and the upper and lower pressing effects are achieved through the screw pad 4 and the snap ring pad 6, and the assembly is completed. The lower flow channel and the upper flow channel are combined to form a flow divider plate channel, so that there are no dead corners inside the channel, it is easy to clean the glue, and it is easy to disassemble. When the thermosetting material rubber is injection molded, the temperature is kept constant and it is not easy to cure; if the glue is cured, the flow divider plate can be disassembled without dead corners and it is easy to clean the glue, which improves the molding quality and injection efficiency and reduces the generation of waste glue.
[0029] An upper pad 12 is provided on the top surface of the upper flow divider plate 1, and a lower pad 13 is provided on the bottom surface of the lower flow divider plate 2.
[0030] A sealing ring groove 2-2 is provided on the outer side of the lower flow channel 2-1 on the lower flow divider plate 2, and a sealing copper wire 14 is provided in the sealing ring groove 2-2. The sealing copper wire 14 can prevent glue leakage from the mating surface of the flow divider plate channel 3 formed by the combination of the upper flow channel 1-1 and the lower flow channel 2-1. When the upper flow divider plate 1 is butted on the lower flow divider plate 2, the sealing copper wire 14 is pre-pressed and sealed.
[0031] The diameter of the injection nozzle channel 8-1 gradually increases from the A end 8-2 to the B end 8-3 to form a conical shape; the A end 8-2 is the glue inlet, and the B end 8-3 is the glue outlet. An upper vertical channel 15 communicated with the flow divider plate channel 3 is provided on the upper flow divider plate 1, and the upper vertical channel 15 is connected and cooperated with the B end 8-3 of the injection nozzle channel 8-1. The diameter of the B end 8-3 is equal to the diameters of the upper vertical channel 15 and the flow divider plate channel 3.
[0032] The diameter of the hot nozzle runner 9-1 gradually decreases from the C end 9-2 to the D end 9-3, presenting a conical shape; the C end 9-2 is the glue inlet, and the D end 9-3 is the glue outlet.

After that, the temperature rapidly rises to the melting temperature. During the process of melting and entering the cavity for molding, the temperature setting needs to be precise. If the temperature is too low, it will affect the flow molding; if the temperature is too high, molecular chain cross-linking and vulcanization will occur, and the rubber material will solidify. After solidification, it is not easy to be heated and melted for molding, and only an appropriate solvent can dissolve it because the mold needs to be cleaned. In this application, the injection nozzle, the sub-manifold, and the hot nozzle are all set as structures that are easy to disassemble and clean. After the solidified rubber material can be cleaned out, the injection molding can be repeated.
[0034] The above has made an exemplary description of the present utility model in conjunction with the accompanying drawings. Obviously, the specific implementation of the present utility model is not limited by the above embodiments.
