Injection Molding Display Unit Grouping Operations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display systems for injection molding machines do not effectively convey the operational relationship between multiple elements during mold closing or opening, making it difficult for operators to ensure that these elements are set in a suitable order to prevent mold damage.
Innovation Solution
A display unit and method that sets operation start conditions, groups elements operating together, and sequences their operations, displaying these relationships in a manner that shows the before and after relationships of core operations, allowing operators to easily verify if the operations meet interlock conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the timings at which a plurality of cores operate are displayed in time series, then the operational information is provided, but it is difficult to understand the operational relationship between cores that must operate in a suitable order
Solution Approach 1:
The display screen is segmented into multiple display areas, with each area dedicated to showing the operational status of a specific core. This segmentation allows operators to see both individual core operations and their relationships across different segments, making it easier to understand the operational sequence and relationships between multiple cores while preventing mold damage.
2Loss of information
If the timings at which a plurality of cores operate are displayed in time series, then the operational information is provided, but it is difficult for an operator to check that the operations of the cores are set in a suitable order
Solution Approach 1:
The patent transitions from a one-dimensional time series display to a two-dimensional display layout where cores are arranged spatially in display areas. This dimensional change allows operators to visually verify the operational sequence and relationships between cores more effectively, as the spatial arrangement combined with timing information provides a comprehensive view for checking suitable operation orders.

AI summary
A display unit of an injection molding machine that displays an order of operations of elements operating during clamp close or open of the injection molding machine, the display unit including a condition setting unit that sets a start condition of the operation; a group setting unit that sets the elements operating in conjunction with each other to be associated with the same group, based on the set start conditions; an order setting unit that sets the order of the operations of the elements associated with the same group, based on the set start conditions; and a display control unit that controls a display unit to display a field showing the group, and to display symbols indicating the operations of the elements associated with the groups in the fields, to show a before and after relationship in accordance with the set order of the operations.
