High-precision in-mold tapered part end face leveling mold

Abstract

The invention discloses a high-precision in-mold tapered part end face leveling mold which comprises an upper mold body and a lower mold body, the upper mold body comprises an upper support (1), an upper base plate (2) and a fixing plate (3), the upper base plate (2) and the fixing plate (3) are fixedly arranged at the bottom of the upper support (1) in sequence, a limiting plate (4) and a discharging plate (5) are arranged below the fixing plate (3) and are integrally and sequentially fixedly arranged, a gap (6) is arranged between the limiting plate (4) and the fixing plate (3), a pier pressing head (7) is slidably mounted between the limiting plate (4) and the fixing plate (3), a pier pressing column (8) is fixedly arranged at the bottom of the pier pressing head (7), penetrates through the discharging plate (5) and extends below the discharging plate (5), a chamfer (9) is arranged at the lower end of the pier pressing column (8), and a pre-pressing rod (10) is further fixedly arranged at the bottom of the pier pressing head (7). The high-precision in-mold tapered part end face leveling mold has the beneficial effects that the structure is compact, the production quality of tapered parts is improved, and the machining consistency of finished parts is improved.

Description

technical field [0001] The invention relates to the technical field of production of tapered parts, in particular to a high-precision mold for leveling the end faces of tapered parts in a mold. Background technique [0002] The structure of the finished tapered part is as follows Figure 1~2 As shown, it includes a conical shell 39, the inner wall and the outer wall of the conical shell 39 are all provided with conical surfaces, the top of the part is provided with an opening, the bottom of the part is closed, and the bottom is provided with a conical shell 39 coaxially arranged The central hole 38, the wall thickness of the conical shell 39 is 1 ~ 2mm. At present, such tapered parts are mainly formed by stamping extension dies. The specific molding steps are to first place the thin plate 37 with the central hole 38 on the top surface of the extension die of the stamping die. The structure of the thin plate is as follows: image 3 As shown, the top surface of the thin plate...

Problems solved by technology

[0003] However, although this stamping die can form tapered parts, there are wavy folds 40 distributed on the large end surface of the formed part around its circumference. The parallelism of the small end face is poor, which greatly reduces the molding quality of the part. The structure of the molded part is as follows Figure 4 shown

In addition, the crests of the wave-shaped corrugations 40 on each processed part are not the same, resulting in different overall heights of the parts, thereby reducing the consistency of the parts
