Abstract
The utility model discloses a punch forming die with better durability. The punch forming die comprises an upper die (1), a lower die (2) and a plurality of guide post structure (3) between the upper die (1) and the lower die (2) and further comprises at least one ball guide pole (4), wherein the ball guide pole (4) is positioned between two adjacent guide post structures (3); one end of the ball guide pole (4) is connected with the upper die (1); and the other end of the ball guide pole (4) is connected with the lower die (2).
Description
Technical field
The utility model relates to technical field of mold, specifically is a kind of punch-forming mold.
Background technology
The punch-forming mold of automotive seat is generally led by lead and pilot hole sliding fit at present, though this simple in structure; Owing to be sliding friction; So durability is relatively poor, promptly guide effect is along with service time is long more, and guide effect and stability are poor more.
The utility model content
The technical problem that the utility model will solve is that a kind of durability punch-forming mold preferably is provided.
The technical scheme of the utility model is; The utility model punch-forming mold, it comprises upper die and lower die, and a plurality of lead structures between upper die and lower die; It also comprises at least one ball guide pillar; The ball guide pillar is between two adjacent lead structures, and an end of ball guide pillar is connected with patrix, and the other end of ball guide pillar is connected with counterdie.
After adopting said structure; The utility model compared with prior art; Have the following advantages: owing between two adjacent lead structures, increased the ball guide pillar; Extra guide frame promptly is provided, and targeting part adopts rolling friction to realize in the ball guide pillar, so the utlity model has durability advantage preferably.
As improvement, said lead structure is four, is divided into the first lead structure, the second lead structure, the 3rd lead structure and the 4th lead structure in regular turn; The ball guide pillar is two, is respectively the first ball guide pillar and the second ball guide pillar; The first ball guide pillar is between the first lead structure and the second lead structure, and the second ball guide pillar distributes the ball guide pillar between the 3rd lead structure and the 4th lead structure like this, and it is more stable to lead, and guide effect is better.
