Description

Technical Field

[0001] This utility model relates to the field of casting molds, specifically to the upper cylinder block mold of a hybrid engine. Background Technology

[0002] Typically, in gating system design, the number and location of gating channels are distributed according to the amount of molten aluminum in each area of ​​the die casting. This aims to ensure that the molten aluminum is evenly distributed throughout the die casting cavity, thus preventing defects such as porosity and sand inclusions in the die casting. However, as the molten aluminum flows evenly into the die casting cavity, the flow rate and cooling speed will result in slight differences in the strength of different areas of the die casting.

[0003] For the upper cylinder block of a four-cylinder engine, its structure includes the cylinder and camshaft area, thus requiring high structural strength. Furthermore, as it is a hybrid engine, its operating conditions differ significantly from conventional internal combustion engines, necessitating even higher structural strength requirements. Therefore, conventional die-casting molds and gating systems for engine upper cylinder blocks cannot meet the requirements of hybrid engine upper cylinder blocks. Utility Model Content
