Pulp Molding Hot Press Lower Mold Guide Rail Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing automatic forming machines for pulp molding products face instability issues with the guide pillar and guide sleeve supporting structure for the hot pressing lower mold, leading to potential failures and increased maintenance time due to insufficient support, especially when the mold surface area is expanded.
Innovation Solution
The introduction of a supporting structure with a sliding block and guide rail system, where a supporting arm extends from the hot pressing lower mold with sliding blocks that clamp onto a guide rail, ensuring balanced rise and fall of the mold, and a stretchable protection cover for dust prevention and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the mold surface area is expanded to increase production capacity, then productivity is improved, but the supporting structure becomes insufficient leading to instability
Solution Approach 1:
The supporting structure is segmented into multiple guide pillars (at least three, preferably four) distributed across the mold surface, with each guide pillar independently supporting a specific region. This segmentation allows the structure to handle larger mold areas while maintaining stability through distributed support points.
Solution Approach 2:
The guide pillars extend vertically from the mold base to provide support in the vertical dimension, creating a three-dimensional supporting framework. This dimensional addition ensures that the expanded mold surface area maintains adequate support without compromising structural stability.
2Ease of manufacture
If the guide pillar and guide sleeve supporting structure is used for the hot pressing lower mold, then ease of manufacture is improved, but reliability deteriorates due to potential failures and insufficient support
Solution Approach 1:
The guide pillars are pre-installed on the mold base plate before assembling the hot pressing lower mold. This preliminary action ensures that the supporting structure is already in place and properly positioned, preventing instability issues before they occur during operation.
Solution Approach 2:
Each guide pillar is strategically positioned at specific locations on the mold base plate where support is most needed. The local quality of support is optimized by placing guide pillars at corners and key structural points, ensuring reliable support throughout the mold assembly.
3Strength
If the hot pressing lower mold is made heavy to increase durability, then strength is improved, but the lift balance becomes unstable leading to tilting and accidents
Solution Approach 1:
Multiple guide pillars are strategically positioned to act as counterbalancing support elements that offset the weight of the heavy hot pressing lower mold. The distributed arrangement of guide pillars creates balanced support forces that maintain lift stability and prevent tilting during the molding cycle.
4Productivity
If maintenance time is reduced to increase productivity, then productivity is improved, but reliability worsens due to lack of proper support leading to frequent failures
Solution Approach 1:
The guide pillars provide beforehand cushioning support that prevents operational failures before they occur. By ensuring proper support and alignment during assembly, the structure prevents instability issues that would otherwise lead to frequent failures and increased maintenance requirements.

Function Achieved in This Case
This solution maintains the stability and balance of the hot pressing lower mold during its rise and fall, ensuring correct clamping with the upper mold, thereby enhancing product quality and reducing maintenance time by preventing tilting and accidents.
Implementation Method 1
a sliding block (432) is fixed on the upright surface on the outside of each supporting arm (431), and can be sleeved on the guide rail (46)... when the hot pressing lower mold (43) rises or falls, the sliding block (432) can rise or fall simultaneously along the guide rail (46)

AI summary
An automatic forming machine for pulp molding product is disclosed. Through an innovative design to ensure stable rise and fall of the hot pressing lower mold, the hot forming zone is optimized. The invention has the following characteristics: On the bottom side of the hot pressing lower mold, a supporting arm is extended downward in each of the four directions. On the supporting arm, a sliding block is fixed. A penetrating hole slot is configured on a base plate at a lower position inside the working space of the hot forming zone at each of the positions corresponding to the supporting arms. The adjacent outer sides of the base plate corresponding to the supporting arms are respectively fixed with a supporting frame. The column surfaces of the supporting frame on the front and rear side are respectively connected with a supporting plate body. The supporting plate body is fixed with a guide rail. The sliding block on the supporting arm is sleeved on the guide rail, so that when the hot pressing lower mold rises or falls, the sliding block can rise or fall simultaneously along the guide rail, maintaining balanced rise and fall of the hot pressing lower mold. Thus, the hot pressing lower mold and the hot pressing upper mold can clamp correctly to enhance product quality.
