Die-casting formation mold for annular shell

Abstract

The invention discloses a die-casting formation mold for an annular shell. The die-casting formation mold for the annular shell comprises a pouring nozzle, a sprue spreader, a left side drawing mechanism, a right side drawing mechanism, a fixed mold and a movable mold. The fixed mold and the movable mold are combined and then jointly define an annular cavity with the head and the tail being closed. The left side drawing mechanism and the right side drawing mechanism each comprise inclined guide columns, a side drawing sliding block and a side drawing lock block. Each side drawing lock block isprovided with a first inclined structure. Each side drawing sliding block is provided with a second inclined structure. The inclined guide columns of each side drawing mechanism are arranged in the corresponding side drawing sliding block in penetrating and sliding manners. The movable mold is provided with a first main groove, a second main groove, a first branch groove, a second branch groove,first communicating grooves and second communicating grooves. The first branch groove is arranged along the outline of the inner cavity wall on the front side of the annular cavity. The second branchgroove is arranged along the outline of the inner cavity wall on the back side of the annular cavity. The groove depths of the first communicating grooves and the groove depths of the second communicating grooves are gradually reduced in the direction close to the annular cavity. The groove bottom faces of the first communicating grooves and the second communicating grooves are inclined faces inclined upwards in the direction close to the annular cavity. By the adoption of the die-casting formation mold for the annular shell, precise and rapid formation is achieved, and therefore the quality is ensured.

Description

technical field [0001] The invention relates to a metal die-casting mold, in particular to a die-casting mold for a ring-shaped shell. Background technique [0002] With the continuous development of the economy, the continuous advancement of science and technology, and the continuous improvement of people's living conditions, people's demand for material consumer goods is very large, both in terms of types and quantities, thus creating good opportunities for manufacturers of material consumer goods. Development platform, thereby accelerating the pace of development of material consumer goods manufacturers. [0003] Among them, in our daily life, we often see metal products, such as ring-shaped shells with closed ends. Since the material of the ring-shaped shell is metal, it is usually formed by using a die-casting mold. [0004] At present, in the process of forming the ring-shaped shell by the existing die-casting mold, the quality of the formed ring-shaped shell is poor ...
