Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile accessory production and processing, particularly to a fender mold. BACKGROUND

[0002] The automobile fender is a body outer plate covering the wheel, and is named fender because its shape is similar to a bird's wing. The main function of the fender is to prevent the sand and mud rolled up by the wheel from splashing to the bottom of the vehicle compartment during the driving of the vehicle. In the production and manufacturing process of the automobile fender, the automobile fender needs to be stamped by a stamping die. The existing automobile fender stamping die needs to slide on the guide rod when stamping. The guide rod is prone to aging and rusting after a long time of use if it is not maintained, thereby affecting the stamping efficiency.

[0003] In the prior art, a patent with the authorization announcement number CN220479967U discloses an automobile fender stamping die. The lower half of the buffer mechanism is provided with a hollow structure. When in use, the oil filler on one side of the lower half of the buffer mechanism is first opened, lubricating oil is injected, then the oil filler is closed, the buffer mechanism is integrally clamped and installed in the installation groove on the upper end surface of the device main body, and then stamping work is performed. When the stamping mechanism is pressed to touch the buffer mechanism to produce a certain buffering effect, the lubricating oil in the lower half of the buffer mechanism will be sprayed out of the oil outlet pipe due to the pressure. At this time, the sponge ring wrapped around the outer surface of the guide rod is located in the inside of the oil storage groove. When the sponge ring enters the oil storage groove, a certain buffering effect is produced in cooperation with the upper half of the buffer mechanism due to a certain frictional extrusion. When the sponge ring is in the inside of the oil storage groove, the lubricating oil sprayed out of the oil outlet pipe will be sprayed on the surface of the sponge ring. At this time, the sponge ring in the slightly contracted state will absorb a certain amount of lubricating oil. When the buffer mechanism moves upward, the sponge ring will move upward together, thereby protecting the outer surface of the guide rod from aging and rusting and increasing the overall service life.

[0004] The device sprays lubricating oil out of the oil pipe by extruding the buffer mechanism, so that the lubricating oil wets the sponge ring.
