Description

Technical Field

[0001] The utility model relates to the field of injection molds, in particular to an injection mold for an automobile air conditioner damper. Background Art

[0002] At present, due to the demand for lightweight cars, more and more auto parts are made of non-metallic materials. Car air conditioner dampers are made of plastic and are usually made by injection molding. Figure 1 The figure shows the structure of an air conditioning damper on a car. The air conditioning damper is provided with a plurality of crisscrossing ribs 111, and the plurality of ribs 111 are staggered to form a grid 112 structure. The air conditioning damper is manufactured by mold injection molding. The shape of the air conditioning damper is relatively complex, and accordingly, the mold core structure used to form the air conditioning damper will also be relatively complex. If the mold core of the integral structure is used to form the air conditioning damper, the processing time of the mold core will be very long, the mold processing cycle will be extended, and the delivery time may be affected. In addition, the mold core of the integral structure is not easy to process, the fault tolerance rate is relatively low, and it is not easy to replace some structural components, and the maintenance and servicing costs are relatively high.
