Injection mold for battery box shell of electric vehicle

Abstract

The invention belongs to the field of electric vehicles, and particularly relates to an injection mold for a battery box shell of an electric vehicle. The injection mold comprises a water tank, wherein the upper end of the water tank is connected with a box cover through screws; a support column is welded to the upper end of the box cover; a mounting plate is welded to the upper end of the support column; an air cylinder is fixedly mounted at the upper end of the mounting plate; an air cylinder rod is arranged at the lower end of the air cylinder, and the air cylinder rod is sleeved with the mounting plate in a sliding manner; a connecting sleeve fixedly sleeves the outer side of the lower end of the air cylinder rod; an upper mold base is welded to the lower end of the connecting sleeve; a pressing plate is connected to the lower end of the upper mold base in a sliding manner; and a hanging rod is welded to the upper end of the pressing plate, and the hanging rod is sleeved with the upper mold base in a sliding manner. A water pump is arranged at the lower end of a water inlet pipe, the water pump sucks water into a convex mold, the water enters the convex mold to jack up a top plate, the water is injected between a battery box and the convex mold for pressurization, and the battery box is separated from the convex mold, so that the battery box is separated from the convex mold more conveniently.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to an injection mold for a casing of a battery box of an electric vehicle. Background technique [0002] Electric vehicles, that is, electric drive vehicles, also known as electric drive vehicles, are also called battery vehicles. Electric vehicles are divided into AC electric vehicles and DC electric vehicles. Generally speaking, electric vehicles use batteries as the energy source, and convert electrical energy into mechanical energy through controllers, motors and other components to control the current and change the speed of the vehicle. The battery box is an important part of electric vehicles and a device for loading batteries. [0003] The battery box of an electric vehicle is mostly made of plastic material. In the prior art, during the injection molding process of the battery box, it is difficult to separate the punch from the battery box, and it is difficult t...
