Description

Technical Field

[0001] This utility model relates to the field of industrial die casting, and then discloses a die casting mold for automobile engine housing. Background Technology

[0002] As the core power component of a car, the performance and quality of the car engine directly affect the overall performance and reliability of the car. As a key structural component of the engine, the engine housing not only needs to provide a stable mounting base for various internal parts of the engine, but also needs to withstand various complex forces generated during engine operation, such as vibration, pressure and temperature changes. Therefore, the engine housing must have characteristics such as high strength, high precision, good sealing and excellent heat dissipation performance.

[0003] In traditional die-casting molds, after the engine housing is die-cast, the demolding process is often difficult due to the tight fit between the housing and the mold. It may require manual assistance with tools for demolding, which is not only inefficient but may also damage the surface of the housing, affecting product quality. In addition, during the die-casting process, a release agent is usually sprayed on the mold surface to facilitate demolding. However, traditional spraying methods may result in uneven spraying, leading to poor demolding in some areas, which affects production efficiency and product quality.

[0004] Therefore, existing die-casting mold devices suffer from problems such as difficulty in demolding and uneven application of release agent during use. Utility Model Content

[0005] In order to overcome the problems of difficult demolding and uneven application of release agent in existing die casting mold devices, a die casting mold for automobile engine housing is proposed.
