Injection Molding Machine Frame Vibration Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Injection molding machines experience significant vibration during operation, which existing technologies have not effectively addressed.
Innovation Solution
The injection molding machine incorporates a frame with a beam and a reinforcing member, such as an H-shaped steel vertical beam, to improve rigidity and reduce vibration by supporting the mold clamping and injection units, with the reinforcing member connected via welding or bolts to enhance structural stability.

Engineering Contradiction Analysis
1Stability of the object's composition
If a conventional frame structure is used to support the mold clamping unit and injection unit, then the device complexity is low and ease of manufacture is high, but the vibration during operation is significant and structural stability is poor
Solution Approach 1:
The frame employs composite structural elements combining beams and reinforcing members to create a rigid yet manageable structure. The H-shaped steel vertical beams combined with horizontal beams and diagonal reinforcing members form a composite framework that achieves high structural stability without excessive complexity.
Solution Approach 2:
The frame structure transitions from a simple planar arrangement to a three-dimensional spatial framework by incorporating vertical beams, horizontal beams, and diagonal reinforcing members that work together in multiple dimensions to resist vibration and maintain structural integrity.
2Object-affected harmful factors
If the frame rigidity is increased to reduce vibration, then the vibration during operation is reduced, but the weight of the frame increases
Solution Approach 1:
The frame is segmented into distinct functional components: vertical H-shaped steel beams for primary support, horizontal beams for connecting platen assemblies, and diagonal reinforcing members for additional rigidity. This segmentation allows each component to be optimized for its specific function while collectively reducing vibration without excessive weight increase.
Solution Approach 2:
Reinforcing members are strategically positioned at specific locations where vibration and stress are most problematic, such as diagonal bracing between vertical and horizontal beams. This localized reinforcement approach reduces vibration effectively while minimizing the overall weight increase compared to uniform thickening of the entire frame.
