Detailed Description

A die guide structure comprises an upper die guide sliding surface 10 and a lower die guide plate 20 which are respectively arranged on an upper die and a lower die, wherein the upper die guide sliding surface 10 and a guide surface 21 of the lower die guide plate 20 are mutually sliding binding surfaces, and an elastic guide block 30 for guiding the upper die guide sliding surface 10 and the lower die guide plate 20 to be bound is arranged at an initial contact end of the upper die guide sliding surface and the lower die guide plate 20.

In the scheme, the initial contact end of the upper die guide sliding surface 10 and the lower die guide plate 20 is the part where collision occurs during die assembly, the elastic guide block 30 is arranged at the position to relieve the impact force caused by the collision on the elastic guide block 30, and the elastic guide block 30 is used for roughly guiding the upper die guide sliding surface 10 to the guide surface 21 of the lower die guide plate 20 with higher precision, so that the die assembly precision is also ensured.

The first embodiment is as follows: the upper end of the lower die guide plate 20 is provided with an elastic guide block 30, and a guide surface 31 of the elastic guide block 30 is flush with and faces the guide surface 21 in a consistent direction. That is, only one elastic guide block 30 is arranged on the lower die, so that the upper die guide sliding surface 10 is firstly contacted with the elastic guide block 30 when the die is closed, the elastic guide block 30 can buffer the impact of the upper die guide sliding surface 10 on the elastic guide block during the die closing, the upper die guide sliding surface 10 is guided to be attached to the lower die guide plate 20, and the lower die guide plate 20 made of rigid material is used for ensuring the die closing precision of the upper die

Example two: the lower end of the upper die sliding guide surface 10 is provided with an elastic guide block 30, and a guide surface 31 of the elastic guide block 30 is flush with the upper die sliding guide surface 10 and faces in the same direction. That is, only one elastic guide block 30 is provided on the upper mold, so that the lower mold guide 20 is first brought into contact with the elastic guide block 30 when the mold is closed.

Example three: the upper end of the lower die guide plate 20 and the lower end of the upper die sliding guide surface 10 are respectively provided with an elastic guide block 30, and the guide surfaces 31 of the two elastic guide blocks 30 face opposite directions and are respectively flush with the guide surface 21 and the upper die sliding guide surface 10. Namely, the elastic guide blocks 30 are provided on both the upper and lower dies, so that one elastic guide block 30 can play an elastic buffering role even if one elastic guide block 30 is broken and damaged.

The initial contact end of the upper die guide sliding surface 10 or the lower die guide plate 20 and the elastic guide block 30 is in a round angle structure, and the corner between the end surface of the elastic guide block 30 and the guide surface 31 thereof is in a round angle structure. The initial contact end of the die guide structure is arranged at the position, and the fillet is arranged at the position to further reduce the impact force. And the fillet structure has certain guide capacity, can guarantee the compound die precision more effectively.

The elastic guide block 30 on the lower die holder 40 extends to the upper end of the lower die holder 40 and is connected with the lower die holder 40 through a bolt. Thus, when the die assembly is impacted, part of the impact force is born by the lower die holder 40, and the lower die guide plate 20 is further protected

The lower end of the lower die guide plate 20 is attached to a positioning step 41 on the lower die base 40, and the upper side surface of the positioning step 41 and the upper die sliding guide surface 10 are arranged at intervals. When the lower die guide plate 20 is installed, the installation accuracy of the lower die guide plate 20 is ensured by the positioning step 41, and meanwhile, the side surface of the positioning step 41 and the upper die guide sliding surface 10 are arranged at intervals, so that the parts are prevented from being damaged due to mutual interference between the side surface and the upper die guide sliding surface.
