Pressure-casting mold for anti-theft lock cases

Abstract

The invention discloses a pressure-casting mold for anti-theft lock cases. The pressure-casting mold comprises a pouring nozzle, a flow division cone, side core-pulling mechanisms, a stationary mold and a movable mold. After the stationary mold and the movable mold are closed, two molding cavities are defined. Each molding cavity is provided with the two corresponding side core-pulling mechanisms,wherein every two side core-pulling mechanisms are located at the left side and the right side of the corresponding molding cavity. The flow division cone is provided with a first flow division groove and a second flow division groove. Each side core-pulling mechanism comprises an inclined guide pillar, a side pulling slide block, a side core-pulling rod and a side pulling lock block. Each side pulling lock block is provided with a first inclined structure. Each side pulling slide block is provided with a second inclined structure. After being closed, the first inclined structures abut against the second inclined structures in a stopping manner. The movable mold is provided with first linear grooves, second linear grooves, first branch grooves, second branch grooves, first communicating grooves and second communicating grooves. The groove depth of each first communicating groove and the groove depth of each second communicating groove are arranged to be gradually decreased in the direction of being close to the molding cavities. The groove bottom face of each first communicating groove and the groove bottom face of each second communicating groove are inclined faces which are inclined upwards in the direction of being close to the molding cavities. By means of the pressure-casting mold, precise and rapid molding is achieved, and thus product quality is guaranteed.

Description

technical field [0001] The invention relates to a die-casting mold for metal, in particular to a precision and rapid-formed die-casting die for an anti-theft lock case. 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 metal locks, etc. Among them, in the metal anti-theft lock, the anti-theft lock shell is made of metal, so it is usually formed by a die-casting mold. [0004] At present, in the process of forming the anti-theft lock case by the existing die-casting mold, due t...

AI Technical Summary

Problems solved by technology

[0004] At present, in the process of forming the anti-theft lock case by the existing die-casting mold, due to the unreasonable design of the die-casting mold, the quality of the formed anti-theft lock case is poor, and only one anti-theft lock case can be formed each time. Therefore, the efficiency is low
