Glass Molding Release Mechanism for Adhesion Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In glass molded product manufacturing, mold and glass material adhesion during press molding leads to reduced productivity due to the need for system pauses to detach the adhering glass material, and existing solutions are not entirely effective in preventing this adhesion.
Innovation Solution
A molding apparatus with a release device that includes a release member, push bar, and release action mechanism, where the release member is inserted into a guide hole in the upper die and has a lower end surface facing the outer peripheral portion of the lower die, and the push bar adjusts the downward pressure to facilitate the separation of the glass material from the mold after pressing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a spring and mold releasing ring are provided to give a separating force after press molding, then the glass material can be separated from the mold, but the system complexity increases and the separating force may not be sufficient to prevent adhesion
Solution Approach 1:
The release member is positioned in advance within the guide hole of the upper die, ready to engage with the glass material immediately upon separation. The push bar is pre-loaded with a spring mechanism that automatically activates when the upper die moves upward, providing immediate separating force without requiring additional complex control systems.
Solution Approach 2:
The release member acts as an intermediary element between the upper die and the glass material. It is inserted into the guide hole and extends downward to contact the glass material, transferring the separating force from the upper die to the glass material effectively, while the push bar serves as another intermediary to amplify and control this force.
2Productivity
If the mold and glass material are separated quickly after pressing, then productivity increases, but the glass material may adhere to the mold due to insufficient separating force
Solution Approach 1:
The release mechanism is designed to be dynamic rather than static. The spring-loaded push bar automatically adjusts its force application based on the separation process. When the upper die moves upward, the spring compresses and then expands to push the release member downward with increasing force, ensuring reliable separation even as the molding cycle progresses quickly.
Solution Approach 2:
The release member is positioned in advance within the guide hole, ready to engage with the glass material immediately upon separation. This preliminary positioning ensures that as soon as the upper die begins to move upward, the release member can immediately contact and push the glass material, preventing adhesion without requiring additional waiting time.
3Ease of operation
If a release member is inserted into the guide hole to face the outer peripheral portion of the lower die, then the glass material can be pushed downward for separation, but the structure becomes more complex
Solution Approach 1:
The release device is segmented into distinct functional components: the release member that contacts the glass material, the push bar that applies force, and the spring mechanism that provides the driving force. Each component is simple in itself but works together to achieve the separation function, making the overall system easier to operate despite the increased structural detail.
Solution Approach 2:
The spring-loaded push bar is designed to be self-activating. When the upper die moves upward during the separation phase, the spring automatically compresses and then expands to push the release member downward, applying force to the glass material without requiring external control or additional operational steps. This self-service mechanism simplifies the overall operation.

Function Achieved in This Case
Ensures the glass material can be reliably released from the mold without system pauses, improving productivity and allowing for efficient separation of the mold and glass material, thus enhancing the manufacturing process.
Implementation Method 1
The release action mechanism moves the push bar and the release member downward along the shaft direction with respect to the press shaft to release the glass material and the upper die

AI summary
A molding apparatus for glass molded product includes a mold, a press shaft and a release device. The release device includes a release member, a push bar, and a release action mechanism. The release member has a lower end surface to face an outer peripheral portion of a molding surface of the lower die of the mold. The push bar adjusts a downward pressure given to the release member. The release action mechanism is provided to hold an upper portion of the push bar movably along a shaft direction of the press shaft. The release action mechanism moves the push bar and the release member downward along the shaft direction to release a glass material and the upper die of the mold when the upper die and the lower die are separated after the glass material has been pressed between the upper die and the lower die.
