The utility model discloses liquid waste collecting vessel bung mould atmoseal formula runner mechanism's technical scheme is: the hot runner injection molding die comprises a die cavity compound plate and a die cavity plate, wherein a pouring gate is arranged on the die cavity compound plate, a main runner is arranged in the die cavity compound plate, and a barrel cover die cavity is arranged in the die cavity plate.
The utility model discloses a waste liquid collecting vessel bung mould atmoseal formula runner mechanism, key feature are connected hot mouth under the runner frame, subchannel and hot mouth intercommunication, and the oral area of hot mouth stretches into in the die cavity board to with the die cavity intercommunication, set up the cylinder in the die cavity doubling plate, connect the needle under the cylinder, the needle passes the subchannel and cooperatees with the export of hot mouth body and hot mouth. During injection, the valve needle is driven by the cylinder to be drawn out from the outlet of the hot nozzle, the sub-runner, the hot nozzle and the cavity are communicated, and the plastic raw material is injected from the pouring gate and the main runner and is injected into the cavity through the sub-runner and the hot nozzle for pressure-maintaining molding. After injection is finished, the cylinder drives the valve needle to act immediately, so that the valve needle is blocked back to the outlet of the hot nozzle to seal the outlet of the hot nozzle, hot nozzle flash can be prevented, the valve needle is sealed neatly, sprue wire drawing is effectively avoided, and product quality is guaranteed.
The utility model discloses a liquid waste collecting bucket bung mould atmoseal formula runner mechanism, the flow distribution plate about the two sides respectively arrange the electric heating pipe that corresponds with the subchannel, electric heating pipe heats flow distribution plate and subchannel to keep warm to the plastic raw materials who pours into in the subchannel into, prevent that the cooling from solidifying and influencing the velocity of flow and product quality. The cavity plate is internally provided with 6 cavities, the number of the hot nozzles and the number of the sub-runners correspond to the number of the cavities, namely six cavities are formed, and six products are produced by one-time injection molding. The sub-runners are symmetrically distributed in a splayed shape, the distance of the runners can be shortened to the maximum extent due to the symmetrical splayed distribution, the injection molding time is shortened, and the production efficiency is improved.
