Injection mold for battery terminals

Abstract

The invention provides an injection mold for battery terminals. An upper mold comprises two upper mold single bodies which are spliced together. An inner mold comprises two inner mold single bodies which are spliced together. The two upper mold single bodies, a lower mold, two upper inner molds and two lower inner molds jointly form a containing cavity used for containing injection molding materials. A forming cavity is formed by an upper rod head, a lower rod mold, the two upper mold single bodies, the lower mold, the two upper inner molds and the two lower inner molds jointly. In this way, an upper rod mold downwards drives the upper rod head to stretch into the containing cavity, the lower rod mold also stretches into the containing cavity to form the forming cavity together with the lower mold, the flowing injection molding materials such as lead is poured into an injection hole, the upper rod mold upwards retracts out of the containing cavity after the forming cavity is full of the injection molding materials and the injection molding materials are cooled, the two upper mold single bodies, the two upper inner molds and the two lower inner molds retract afterwards to be separated, and the lower rod mold moves upwards to eject a formed battery terminal out of the lower mold. Accordingly, by the adoption of the injection mold for the battery terminals, efficient injection molding of special-shaped workpieces such as the special-shaped battery terminals can be achieved, and the special-shaped workpieces can be smoothly taken out; and the action is harmonious, the structure is novel and reasonable, the cost is low, and the practicability is high.

Description

[0001] The patent application of the present invention is a divisional application of Chinese patent application number 2015101919516. The application number of the original application is 2015101919516, and the application date is April 22, 2015. The title of the invention is a battery terminal injection mold. technical field [0002] The invention relates to the field of injection molds, in particular to a battery terminal injection mold capable of injection-molding special-shaped battery terminals. Background technique [0003] The battery terminal is an important part of the battery. It is usually produced and processed by a convenient injection molding process. In the injection molding process of the battery terminal, an injection mold is required. The structure of the battery terminal injection mold is well known. The new patent CN201320223246.6 discloses a casting mold for battery connection terminals, including: a bottom plate for providing support and positioning; a ...

AI Technical Summary

Problems solved by technology

[0004] Injection molds similar to the aforementioned utility models are widely used in the market, but they have roughly the same structure as other battery terminal injection molds on the market, and can only inject battery terminals with relatively simple shapes, and cannot inject molds with more complicated shapes. Such as Z-shaped, L-shaped, and battery terminals with irregular structures such as multiple high and low concave-convex edges. The main reason is that the battery terminals with abnormal structures will cause them to be stuck in the mold even after injection molding with the aforementioned mold, making it difficult to take out the finished product smoothly. , the complexity of the process and the consideration of the cost make the battery terminals with special-shaped structures have to resort to other complex and high-cost processes, which brings a lot of trouble to people.
