Injection mold for lithium battery case

Abstract

The invention discloses an injection mold for a lithium battery case. The injection mold comprises an auxiliary device and a molding device, wherein the auxiliary device comprises an injection moldingport, an L-shaped pull rod and a fixed die; a molding part comprises an inner core, a moving die, an outer die, an inverted L-shaped pull rod and a push plate; the L-shaped pull rod is fixed on the push plate; the auxiliary device can be mutually nested with the molding device, so that the moving die, the fixed die and the outer die mutually enclose to form an injection molding cavity, and the inner core is filled into the injection molding cavity to form an injection molding die cavity of the lithium battery case; an injection molding port is communicated to the injection molding die cavity;two long sides of the inner core are outward protruded to form two circular arc shapes; the auxiliary device and the molding device can be vertically separated, so that the L-shaped pull rod and theinverted L-shaped pull rod are mutually hooked to drive the push plate to push the molded lithium battery case. The lithium battery case produced by the injection mold disclosed by the invention has the advantages that the deformation resistance is realized, inward concave is not easy to cause, and a lithium battery can be conveniently changed.

Description

technical field [0001] The invention relates to an injection mold, in particular to an injection mold for a lithium battery box. Background technique [0002] Lithium battery box is used to install lithium battery. Generally, it includes a bottom plate, two opposite long plates and two opposite short plates, and the two long plates and two short plates are enclosed on the bottom plate to form a cavity that can be loaded with a lithium battery. During the actual use of the injection mold for the lithium battery box, the inventors found that the two long boards would sag inwards. Aluminum battery boxes are usually sealed after the battery is installed. This sealing environment can easily cause the two long boards to sag inward. And stick to the aluminum battery. Like this, when replacing lithium battery, because the two long boards of depression are difficult to return to original state, just be difficult for installing the lithium battery that replaces. [0003] And the li...

During the actual use of the injection mold for the lithium battery box, the inventors found that the two long boards would sag inwards. Aluminum battery boxes are usually sealed after the battery is installed. This sealing environment can easily cause the two long boards to sag inward. And stick to the aluminum battery

In this way, when replacing the lithium battery, it is difficult to install the replaced lithium battery because the sunken two long plates are difficult to return to the original state.
