[0002] Automotive exterior parts are an important component of automobiles, and injection molding is a crucial process in the processing of automotive exterior parts. Injection molding machines are used to shape automotive exterior parts. However, during the injection molding process, a hot shear structure is usually used to facilitate the trimming of the gate.

[0003] Existing injection molding hot shear structures generally consist of two parts: a multi-directionally movable blade and a heating device. The heating device heats the blade, and the heated blade is used to hot shear the gate of automotive exterior parts. However, during use, the quality of the hot shearing is not high, and burrs are easily generated, requiring secondary processing. In addition, existing hot shear structures are not convenient for fixing various irregularly shaped workpieces, and automotive exterior parts have diverse shapes, resulting in a limited range of applications and low practicality.
