Die core locating mechanism of automobile skylight guide rail bending die

Abstract

The invention belongs to the technical field of automobile part machining equipment and provides a die core locating mechanism of an automobile skylight guide rail bending die. The die core locating mechanism comprises a lower die plate, a lower die core locating part, an upper die plate and an upper die core locating part, wherein the lower die plate is provided with an arc bending assembly; a lower die core used for containing a guide rail is movably connected to the lower die plate and located above the arc bending assembly; the lower die core locating part is arranged on the arc bending assembly; a lower die core retaining part movably abut against the two opposite side faces of the lower die core; the upper die plate is located above the lower die plate; an upper die core is movably connected to the upper die plate; the lower end face of the upper die core movably abuts against the upper end face of the lower die core; the two ends of the upper die plate are both provided with pressing assemblies; the lower ends of the pressing assemblies movably abut against the ends of the upper die core; and the upper die core locating part is arranged on the pressing assemblies and movablyabuts against the two opposite side faces of the upper die core. Compared with the prior art, the die core locating mechanism of the automobile skylight guide rail bending die has the advantages of being capable of ensuring that the positions of the upper die core and the lower die cores are correct before die closing.

Description

technical field [0001] The invention belongs to the technical field of auto parts processing equipment, and in particular relates to a mold core positioning mechanism of an auto sunroof guide rail bending mold. Background technique [0002] The car sunroof guide rail is the running track of the windows installed on the roof of some cars for lighting and ventilation. Here, the sunroof guide rail can be used to facilitate the driver to open and close the car sunroof manually or automatically. The sunroof guide rails are all made of aluminum during production. The profile is straight when it is extruded, but the actual skylight guide rail of the final product is curved, so it is necessary to use a special bending machine for the bending process. Most of the existing skylight guide rail bending machines use nylon cores , The texture of the nylon mold core is relatively soft. During the mold closing and bending process, the bending accuracy of the guide rail may not meet the stan...

[0002] The car sunroof guide rail is the running track of the windows installed on the roof of some cars for lighting and ventilation. Here, the sunroof guide rail can be used to facilitate the driver to open and close the car sunroof manually or automatically. The sunroof guide rails are all made of aluminum during production. The profile is straight when it is extruded, but the actual skylight guide rail of the final product is curved, so it is necessary to use a special bending machine for the bending process. Most of the existing skylight guide rail bending machines use nylon cores , The texture of the nylon mold core is relatively soft. During the mold closing and bending process, the bending accuracy of the guide rail may not meet the standard due to the excessive deformation of the nylon mold core itself. In severe cases, the guide rail will be damaged.
