Problems solved by technology

The battery pack box is a key part of new energy vehicles. The existing battery pack box is basically welded with aluminum profiles. The production efficiency is low, the strength of the welded parts is poor, and the product has a risk of leakage due to weld defects.
And for the existing battery pack box, considering the welding process and strength issues, its wall thickness is difficult to make very thin, which is not conducive to lightweight design

Embodiment

[0052] Such as figure 1 and figure 2 As shown, the present invention provides a method for manufacturing a battery pack box, including:

[0053] Provide die-casting mold 1;

[0054] Inject the die-casting material into the die-casting mold 1;

[0055] After the die-casting material is cooled, demoulding is carried out.

[0056] In this embodiment, the die casting material is AlSi10MnMg.

[0057] In this embodiment, before injecting the die-casting material into the die-casting mold 1, the die-casting mold 1 is vacuumed to ensure that the vacuum degree in the die-casting mold 1 is less than 100 mbar.

[0058] In this embodiment, a vacuum pump is used to evacuate the die-casting mold 1 .

[0059] In this embodiment, when the die-casting material is injected into the die-casting die 1, the die-casting die 1 is heated to ensure that the temperature of the die-casting die 1 is 220°C-230°C.

[0060] In this embodiment, a mold temperature machine is used to heat the die-castin...

Abstract

The invention discloses a manufacturing method of a battery pack box body and the battery pack box body, and relates to the technical field of battery pack box body manufacturing. The manufacturing method comprises the following steps of providing a die-casting die; injecting a die-casting material into the die-casting die; and demolding after the die-casting material is cooled. The battery pack box body is integrally formed by adopting a die-casting process, so that the strength of the battery pack box body is ensured, the wall thickness of the battery pack box body is reduced, and the lightweight effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of battery pack case manufacturing, and more particularly relates to a method for manufacturing a battery pack case and the battery pack case. Background technique [0002] Due to the increasing shortage of energy and environmental pollution, automobile lightweight and new energy vehicles have become the main direction of the development of the automobile industry. The battery pack box is a key part of new energy vehicles. The existing battery pack box is basically welded with aluminum profiles, which has low production efficiency and poor weldment strength, and there is a risk of product leakage due to weld defects. And for the existing battery pack box, considering the welding process and strength issues, it is difficult to make the wall thickness very thin, which is not conducive to lightweight design. Contents of the invention [0003] The purpose of the present invention is to address the deficiencie...
