Molded Article Production System with Independent Vertical Mold Movement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional resin sealing and molding systems require separate driving mechanisms for the frame member and bottom member, limiting their configuration and efficiency in resin molding processes.
Innovation Solution
A molded article production system with a mold-driving mechanism that includes a lower base, support member, elevating platen, first and second driving mechanisms, and auxiliary connecting members, allowing independent vertical movement of the circumferential and bottom members to form and release the cured resin without significant force on the molded article.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If separate driving mechanisms are used for the frame member and bottom member, then the mold can be opened and closed, but the configuration is limited and efficiency is reduced
Solution Approach 1:
The driving mechanism is segmented into a main driving mechanism for the frame member and auxiliary driving mechanisms for the bottom member, allowing independent control of each component while maintaining system coordination
Solution Approach 2:
The system transitions from static fixed positions to dynamic adjustable positions, where the bottom member can move independently vertically to adapt to different molding requirements, improving productivity without excessive complexity
2Ease of operation
If the mold is opened widely to remove the molded article, then the article can be accessed, but significant force is applied to the molded article
Solution Approach 1:
The mold opening process is segmented into multiple independent movements: the frame member moves horizontally to open, while the bottom member moves vertically to release the molded article, allowing removal without wide opening and excessive force
Solution Approach 2:
The bottom member is preliminarily positioned to support the molded article before the frame member opens, and then moves vertically to release the article in advance, preventing damage during removal
3Adaptability or versatility
If a single mold structure is used, then the system is simple, but substrates with different thicknesses cannot be produced
Solution Approach 1:
The bottom member is designed with vertical movability, transforming the mold from a static structure to a dynamic one that can adjust its position to accommodate different substrate thickness requirements, enabling versatility without complex multi-mold systems
Solution Approach 2:
The single mold structure is designed to perform multiple functions by allowing the bottom member to move vertically to different positions, enabling the production of substrates with various thicknesses using the same mold rather than requiring different molds

AI summary
A molding module 2 includes: a mold 11 including a lower mold 10 and an upper mold 7 facing each other; a cavity 12 provided in the lower mold; a bottom member 9 forming the inner bottom surface 14 of the cavity; a circumferential member 8 forming the inner circumferential surface 13 of the cavity; a mold-driving mechanism for opening and closing the mold 11; a lower base 3; a support member 4 vertically provided on the lower base; an upper base 5 provided in the upper portion of the support member; and an elevating platen 6 mounted on the middle portion of the support member in a vertically moveable manner. Motors 16 and 23 included in the mold-driving mechanism are respectively attached to the lower base and the elevating platen. The upper mold is attached to the upper base. The circumferential member is connected to the elevating platen. The bottom member is connected to the motor 23. The circumferential member is driven vertically by the elevating platen which is driven vertically by the motor 16. The bottom member is driven vertically by the motor 23.
