Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, specifically to a stamping die for automobile fenders equipped with an ejection mechanism. Background Technology

[0002] The fender, also known as the wheel arch, is an important component on the outside of a car body. Located outside the wheels, it is typically positioned behind the front bumper, under the hood, and above the front steering wheels. Depending on its installation location, fenders can be divided into front fenders and rear fenders. The main function of this component, based on fluid dynamics principles, is to reduce the drag coefficient, thereby optimizing vehicle stability. Fenders are mostly produced by stamping, where raw materials are placed into a stamping die and pressed. Traditionally, material removal after stamping is done manually, which is inefficient. To improve this, a stamping die for automotive fenders with an ejector mechanism has been proposed.

[0003] For example, the automobile shell stamping die disclosed in the authorization announcement number CN221454002U includes a base plate, a die frame fixedly connected to the upper side of the base plate, a lower die slidably connected to the inner side of the die frame, a fixing component on one side of the die frame, a support frame fixedly connected to the upper side of the base plate, a top plate fixedly connected to the upper side of the support frame, a hydraulic cylinder fixedly connected to one side of the top plate, a connecting plate A fixedly connected to the shaft end of the hydraulic cylinder, a T-shaped guide rod on the upper side of the connecting plate A, a fixing plate fixedly connected to one side of the T-shaped guide rod, and an upper die fixedly connected to the lower side of the fixing plate.

[0004] Although it achieves the goal of lifting the car body after stamping and quickly demolding by setting up a support frame, top plate, hydraulic cylinder, T-shaped slide plate, connecting plate A, T-shaped guide rod, fixed plate, upper mold, lower mold, buffer spring, connecting plate B, and connecting block, it can also lift up the leftover material for easy collection.

[0005] However, this does not solve the problem that existing stamping dies are not conducive to convenient linkage lifting of the blades during use, nor to the quick ejection and separation of the blades from the lower die base, nor to the protection of operators, thus affecting the convenience of blade lifting and output and the safety of die use. Utility Model Content

[0006] The purpose of this utility model is to provide a stamping die for automobile fenders with an ejection mechanism, so as to solve the problems mentioned in the background art, such as the stamping die not being convenient for lifting the fender in a coordinated manner, which is not conducive to quickly ejecting and separating the fender from the lower die base and protecting the operator, thus affecting the convenience of fender lifting and output and the safety of the die during use.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a stamping die for an automobile fender with an ejection mechanism, comprising a die frame and a lower die base. The lower die base is disposed inside the die frame and is fixedly connected to the die frame. An upper die base is disposed inside the die frame above the lower die base and is slidably connected to the die frame. Multiple sets of equally spaced electric push rods are installed on the outer wall of the lower die base. Each electric push rod has a rack installed at its output end, and the rack extends into the lower die base and is slidably connected to it. The lower mold base on one side of the rack is equipped with multiple sets of L-shaped frames at equal intervals, and the L-shaped frames are fixedly connected to the lower mold base. The top of each L-shaped frame is equipped with a lead screw, and the lead screw is movably connected to the L-shaped frame. Gears are fixedly installed on the surface of each lead screw, and the gears mesh with the rack. Threaded sleeves are provided on the surface of the lead screw above each gear, and the threaded sleeves are threadedly connected to the lead screw. A sleeve is provided on the outer wall of each threaded sleeve, and the sleeve is fixedly connected to the threaded sleeve. A slider is installed on the outer wall of each sleeve, and the slider is slidably connected to the L-shaped frame.

[0008] Preferably, a protective cover is provided on the outside of the upper mold base, and the protective cover is fixedly connected to the upper mold base.

[0009] Preferably, the protective cover has a telescopic cover inside, and the telescopic cover is slidably connected to the protective cover.

[0010] Preferably, the top of the telescopic cover is equipped with multiple sets of springs at equal intervals, and the springs are connected to the protective cover.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the stamping die not only realizes convenient linkage lifting of the blade plate, which facilitates the quick ejection and separation of the blade plate from the lower die base and protects the operator, but also improves the convenience of blade plate lifting output and the safety of die use.

[0012] (1) Install the upper die base onto the stamping machine and connect it to the power source of the stamping machine. Place the raw material above the lower die base and operate the stamping machine to drive the upper die base to press down. The die frame provides sliding support for the upper die base. With the cooperation of the lower die base and the upper die base, the fender is stamped and processed. After processing, the electric push rod drives the rack to move. The rack drives the lead screw to rotate on the surface of the L-shaped frame through the gear. The lead screw drives the sleeve to move upward through the threaded sleeve. With the cooperation of multiple sets of sleeves, the fender is lifted, thereby lifting the fender from the surface of the lower die base and separating it from the lower die base to complete the stamping operation of the fender. This realizes convenient linkage lifting of the fender, which facilitates the quick ejection and separation of the fender from the lower die base and improves the convenience of fender lifting output.

[0013] (2) When the upper die base moves downward, the upper die base drives the protective cover and telescopic cover to move downward. When the telescopic cover contacts the surface of the stamping machine, the protective cover continues to move downward. The telescopic cover is subjected to a reverse force, which squeezes the spring and drives the spring to contract, thereby causing the telescopic cover to contract into the interior of the protective cover. With the cooperation of the protective cover and the telescopic cover, the space around the lower die base is protected to prevent flying chips from being generated during the stamping process and causing injury to the operator. The purpose of the spring design is to avoid the protective cover and the telescopic cover from hard contacting the surface of the stamping machine, which would cause damage to the protective cover and the telescopic cover, thereby extending their service life, facilitating the protection of the operator, and improving the safety during use.
