Description

Technical Field

[0001] The utility model relates to the technical field of injection molding processing, in particular to an automatic shearing device for the material head of an injection molding part of an automobile front door inclined handle. Background Art

[0002] In the existing injection molding processing technology, especially in the production process of automobile front door inclined handle injection molding, a significant technical defect is the processing method of the material head. The traditional method relies on manual operation, that is, the staff needs to manually cut and grind the material head connected to the injection molding body. This method has several significant shortcomings: 1. It requires extremely high technical and proficiency of the staff. Since the cutting and grinding process of the material head requires fine operation, the shearing accuracy of the staff depends entirely on their personal quality and experience, which makes it difficult to effectively control the qualified rate of the finished injection molding parts; 2. The manual operation method is inefficient and has high labor costs. In the fast-paced and high-efficiency modern production environment, the manual removal of the material head is not only time-consuming and labor-intensive, but also requires a large amount of human resources investment, thereby increasing production costs; 3.
