Mold for molding vehicle-mounted cigarette lighter outer shell

Abstract

The invention discloses a mold for molding a vehicle-mounted cigarette lighter outer shell. The mold is characterized in that the mold comprises a lower mold mechanism and an upper mold mechanism, andthe lower mold mechanism and the upper mold mechanism are matched with each other to form the integral mold; the lower mold mechanism comprises a lower mold base, multiple lower cushion feet, a firstlower mold plate, a second lower mold plate, a third lower mold plate and a fourth mold plate; the multiple lower cushion feet are arranged at the bottom of the lower mold base; a material guiding plate is arranged at the top of one end of the lower mold base, and a false detection device is arranged at the top of the other end of the lower mold base; the upper mold mechanism comprises an upper mold base, multiple upper cushion feet, a first upper mold plate, a second upper mold plate, a third upper mold plate and a fourth upper mold plate; the multiple upper cushion feet are arranged at thebottom of the upper mold base; and the first upper mold plate, the second upper mold plate, the third upper mold plate and the fourth upper mold plate are sequentially arranged at the top of the uppermold base. The mold for molding the vehicle-mounted cigarette lighter outer shell is high in machining precision and production efficiency, low in rejection rate, high in material utilization rate and low in production cost.

Description

technical field [0001] The invention relates to the technical field of molding molds for processing vehicle parts, in particular to a molding mold for a vehicle-mounted cigarette lighter shell. Background technique [0002] The car cigarette lighter is a common accessory on the car. If the driver wants to smoke while driving, but does not want to stop to light a cigarette, he only needs to press the car cigarette lighter. The resistance wire heats up. When the resistance wire of the car cigarette lighter reaches the cigarette lighting temperature, the bimetal sheet is automatically opened after being heated, and the bimetal sheet pops out from the resistance disc, and the driver can use the car cigarette lighter to light a cigarette, which greatly facilitates the driver. Lighting cigarettes improves the safety of driving. [0003] The ultra-thin-walled car cigarette lighter metal shell with shallow conical surface conforms to the characteristics of a stepped deep cylindrica...

AI Technical Summary

Problems solved by technology

During the stamping and forming process, the shallow conical surface is easily unstable and wrinkled, and the ultra-thin parts are prone to cracking, which directly affects its function and may even be scrapped.

Moreover, at present, the metal shell of the vehicle-mounted cigarette lighter requires more than 3 sets of molds to complete the stamping process of the jacket parts. There is a poor fit between multiple molds, which will cause poor appearance and size of the product and affect performance.

Lead to problems such as low product processing accuracy, low production efficiency, high scrap rate, low material utilization rate and high production cost
