Problems solved by technology
After the fan is injected, it is necessary to use a dynamic balance measuring instrument to check whether the fan meets the dynamic balance requirements. If it does not meet the dynamic balance requirements, it will cause the fan to vibrate when it rotates, the noise is large, and the service life is low. At this time, The injection mold needs to be repaired, and the side where the deviation occurs on the mold cavity is polished with a polishing machine, and then re-injected until it passes the test

The invention relates to a mechanism for adjusting the dynamic balance of an automobile fan mould by using the eccentricity. The fan mould comprises a cavity and a core which form the mould cavity of a fan. The fan comprises blades which are externally connected by fixed rings. The mechanism is characterized in that the core comprises a main core, the upper part of the main core forms a blade mould cavity with the cavity, the outer wall of the main core is tightly fixed on a push plate, the push plate is externally provided with a fixed ring, the fixed ring is internally provided with a conical hole, the conical hole is internally provided with a movable ring, the bottom surface of the movable ring contacts the top surface of the push plate, the inner side wall of the movable ring forms the outline of the fixed ring, and the center of the internal diameter of the movable ring keeps an eccentric distance with the center of the external diameter of each blade of the fan. The mechanism has simple structure and high efficiency, is convenient to debug, can not be scrapped due to the repair of the cavity of the fan mould and can save time.
Description
technical field [0001] The invention relates to a plastic mould, in particular to an eccentric adjustment dynamic balance mechanism of an automobile fan mold, which belongs to the field of plastic moulds. Background technique [0002] When the engine and the motor are in operation, the heat dissipation is very large, and fan cooling is usually required. The fan includes several fan blades, and the outside of each fan blade is connected by a fixing ring. After the fan is injected, it is necessary to use a dynamic balance measuring instrument to check whether the fan meets the dynamic balance requirements. If it does not meet the dynamic balance requirements, it will cause the fan to vibrate when it rotates, the noise is large, and the service life is low. At this time, The injection mold needs to be repaired, and the side of the mold cavity that is deviated is polished with a polishing machine, and then re-injected until it passes the test. However, the method of debugging w...
