Die-casting mold base for new energy vehicle battery pack - Battery Pack - Giga-Casting Mould Base - Products - Kejia (Changxing) Mould Base Manufacturing Co., Ltd.

Product Description

01.

Efficient and lightweight

The new energy vehicle battery pack is a battery component composed of multiple battery cells. Different from the lead-acid batteries used in traditional fuel vehicles, the new energy vehicle battery pack is made of high-efficiency and lightweight materials such as lithium-ion batteries, sodium-ion batteries, and hydrogen fuel cells, which can better meet the needs of new energy vehicles and energy storage systems.
02.

Through security performance evaluation

Due to integrated die casting technology, the weight of the mold base increases. The safety performance assessment of the mold base is an important part to ensure the safety and reliability of the mold in the process of use. The assessment includes the structural safety of the mold, the safety of the material, the safety of the heat treatment process. Through the assessment, potential safety hazards can be found in time and corresponding measures can be taken to improve.
03.

Using P20 forgings with good mechanical properties

P20 forged steel with high strength, high heat resistance and high wear resistance is usually used in the material selection of the mold base. P20 has good mechanical properties and can meet the requirements of the mold base in the high-pressure casting process. At the same time, the excellent processing performance and heat treatment performance can ensure the processing quality and service life of the mold base.

Product Application

Die-casting mold base for new energy vehicle battery pack

Features
1. Large battery capacity. A battery pack contains multiple cells, so it can provide greater storage energy, and the overall volume and weight are not too large.
2. Battery management system is more complete. Due to the new energy vehicle battery pack inside the battery monomer number is more, so need more accurate, safe battery management system (BMS) to manage its working state, so as to ensure the safe operation of the battery.
3. More comprehensive data collection. In order to better monitor the operating status of the battery, the new energy vehicle battery pack has more sensors and detection devices than a single battery unit, which can realize more comprehensive and accurate data collection and analysis.
4. Deep charging and discharging. New energy vehicle battery packs are capable of deeper charging/discharging operations, making them last longer and better adapted to the needs of electric vehicles and energy storage scenarios.

Product Parameters

The traditional car body structure is usually composed of hundreds of parts with different shapes and materials, which require multiple processes such as stamping, welding, and fastening to complete assembly.

Composite deep hole processing technology of super large plate.

Mold base side composite angled through-frame hole is die-casting mold in the cooling water circulation system through the hard tube connected to the core of the important structure, in the die-casting production process played a role in the rapid cooling mold molding. Due to the structure of the outer hard tube through the mold core, the position of the holes is very demanding. For this reason, we purchase high-precision five-axis deep hole machine, using special processing technology, one processing in place, can meet the technical parameters of die-casting products.
Flatness requirement of super large plate: +-0.08.

The flatness accuracy of the mold refers to the flatness error between the working surface and the reference surface of the mold, and the commonly used indexes are flatness, parallelism and perpendicularity, etc. In the process of mold manufacturing and use, the mold flatness accuracy is required to ensure the dimensional stability of the product and production efficiency. Improvement of mold flatness accuracy requirement is directly related to product quality and production efficiency. In order to meet the requirements of mold base flatness, most of the deformation is removed before finishing, stress relieving, and machining the front and back surfaces several times to meet the flatness requirements.
Cavity perpendicularity requirement: +-0.02.

Quality inspection and control is an important means to ensure the quality of the mold base. In the manufacturing process of the mold base, it is necessary to carry out strict quality inspection of each component to ensure that the dimensional accuracy, surface quality, material properties and so on meet the design requirements. At the same time, it is also necessary to monitor the use of the mold, discover and deal with quality problems in time, and ensure the stability and reliability of the mold.
Assembly requirements

We will carry out the final cleaning and trial assembly of the mold base after processing and testing is completed, check the assembly of all parts and the main plate, and confirm the fit gap between each part in advance to ensure the mold core can complete test after loading to the mold base.
