Shaping mold of X-shaped ring

Abstract

The invention discloses a shaping mold of an X-shaped ring. The shaping mold comprises an upper mold plate, a lower mold plate and a mold head assembly, wherein the mold head assembly is provided witha mold cavity for shaping the X-shaped ring; salient points extending in the internal upward direction and extending in the external upward direction are formed in the upper part of the mold cavity correspondingly, salient points extending in the internal downward direction and extending in the external downward direction are formed in the lower part of the mold cavity correspondingly, and the mold head assembly treats a ring-shaped circular cone surface on which a connecting line of two of the salient points which are away from each other is located as a mold dividing surface to be divided into a concave mold and a convex mold which is matched with the concave mold; and in one group of the mold head assembly, one of the concave mold and the convex mold is an upper mold head which is installed on the upper mold plate, and the other one of the concave mold and the convex mold is a lower mold head which is installed on the lower mold plate. Due to the fact that the ring-shaped circularcone surface on which the connecting line of two of the salient points which are away from each other is located is the mold dividing surface, on the parts of the convex mold and the concave mold on which the mold cavity is located, cross section groove widths are in a decrement shape from the groove openings to the groove bottoms, machining form the external to the internal using a profiling cutter head is convenient, the machining efficiency can be fully improved, and the machining precision is ensured.

Description

technical field [0001] The invention relates to the technical field of molds, and more specifically, relates to an X-shaped ring forming mold. Background technique [0002] In many products, there is an X-shaped rubber sealing ring (hereinafter referred to as X-ring) that plays a sealing role. In order to ensure that the X-ring has a good sealing function, most of the X-rings have a 45° parting surface. In the production process, X-rings are processed by vulcanization and pressing through X-ring rubber molds, and the quality of X-ring rubber molds will directly affect the quality of X-ring parts. [0003] At present, the mold used to form the X-shaped ring mainly includes an upper die head and a lower die head, wherein the upper die head is set on the upper die head, and the lower die head is set on the lower die head. circle cavity. Generally, the horizontal plane is used as the parting surface, so that the upper die head has an upper groove, and the groove cavity is the ...
