Description

Technical Field

[0001] The utility model relates to the technical field of molding dies, in particular to a molding die for processing an emergency unlocking handle base for an automobile door. Background Art

[0002] The car door emergency unlock handle base is a component on the car door, used to fix the emergency unlock handle. The emergency unlock handle is usually located on the inside of the door and is used to open the door from inside the car in an emergency. The design and manufacture of the handle base need to ensure stability and durability so that the door can be effectively opened when needed. In the processing and production process of the car door emergency unlock handle base, the molding mold plays a vital role. This special mold is precisely designed and manufactured according to the specific shape and structure of the base to ensure that parts that meet the requirements can be produced.

[0003] The existing Chinese patent with announcement number CN209504763U discloses a molding mold for automobile handle accessories, including a mold body, a mold body feed port, a feed flow channel and a molding module. The molding module is provided with a hook mold cavity and a base mold cavity. The molding module includes a molding A plate and a molding B plate. The molding A plate is overlapped with the molding B plate. A movable molding slider and at least one molding groove are provided on the top of the molding B plate. A plurality of strip-shaped grooves are provided between the molding groove and the molding slider. The molding slider is provided with at least one molding recess B. At least one molding recess A adapted to the molding recess B is provided at the bottom of the molding A plate. The molding recess A and the molding recess B are combined to form a hook mold cavity. At least one insert is provided on the molding A plate. The bottom of the insert is adapted to the molding groove. The bottom of the insert is combined with the molding groove to form a base mold cavity.

[0004] Although the above scheme has a simple structure and a reasonable design, it is inconvenient to replace the lower mold of the molding mold. At the same time, after the injection molding is completed, the plastic will produce a certain adhesion with the mold surface due to the high-temperature heating in the mold. When the mold temperature is high, demolding becomes more difficult, which affects the production efficiency. Therefore, it does not meet the existing needs. In this regard, we propose a molding mold for processing the base of the emergency unlocking handle of a car door. Utility Model Content
