Asymmetric Column Press for Wider Mold Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional casting machine presses are limited in accommodating molds that are wider or longer than the distance between the columns, leading to inefficient use of pressing capacity and increased maintenance costs due to the need for larger presses and complex mechanisms to manage tool changes.
Innovation Solution
A press design with two front columns spaced further apart than the two rear columns, allowing for the insertion and removal of wider or longer molds, while maintaining a compact and stable structure by keeping the rear columns close together, thus enabling better utilization of the pressing capacity and simplifying maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the distance between columns is increased to accommodate wider or longer molds, then the adaptability for different mold sizes is improved, but the overall dimensions of the press increase and the structure becomes more complex
Solution Approach 1:
The column structure is segmented into front columns and rear columns with different spacing configurations. The front columns are spaced wider apart to accommodate larger molds, while the rear columns maintain closer spacing to preserve structural compactness. This segmentation allows the press to handle diverse mold sizes without requiring uniform expansion of the entire structure.
Solution Approach 2:
Different regions of the press structure are given different properties: the front column region has larger spacing to provide mold accommodation flexibility, while the rear column region maintains smaller spacing to preserve structural stability and compactness. This local differentiation resolves the contradiction between adaptability and structural complexity.
2Adaptability or versatility
If the distance between columns is increased to use wider tools or tools with slides, then the versatility for different tool configurations is improved, but the overall press dimensions increase requiring more space for supply lines and control units
Solution Approach 1:
The column pairing is segmented into front and rear groups with different spacing. The front columns are positioned wider apart to accommodate tools with slides or wider configurations, while the rear columns remain closely spaced. This segmentation enables the press to handle diverse tool configurations without expanding the overall press footprint.
Solution Approach 2:
The solution addresses the spatial constraint by creating asymmetric column spacing in the horizontal plane rather than uniformly expanding in all dimensions. This dimensional differentiation allows the press to accommodate wider tools through selective front column spacing while maintaining compact rear column spacing, effectively utilizing space in different directional dimensions.
3Device complexity
If a conventional press with uniform column spacing is used, then the structural simplicity is maintained, but the pressing capacity cannot be fully utilized for larger molds
Solution Approach 1:
The column structure is divided into front and rear segments with different spacing characteristics. The front columns are spaced wider to accommodate larger molds and utilize pressing capacity fully, while the rear columns maintain closer spacing to preserve structural simplicity. This segmentation allows the press to handle larger molds without significantly increasing overall structural complexity.
Solution Approach 2:
The press structure exhibits local quality differentiation where the front column region is optimized for mold accommodation with wider spacing, while the rear column region maintains simpler, closer spacing. This local optimization enables full utilization of pressing capacity for larger molds while preserving overall structural simplicity.

AI summary
The invention relates to a press for a casting machine and a casting machine with such a press. The press has a baseplate, an upper frame and a movable clamping platen, with two front columns and two rear columns arranged at the corner zones of the plates and at the corner zones of the upper frame. These columns extend through suitable through openings in the movable clamping platen and are fixed to the baseplate at the stationary upper frame. The press is characterized in that the front columns have a greater distance from one another than the rear columns. Because of this, essentially wider or longer permanent molds or those with side-protruding slides, up to a width corresponding to the increased distance apart of the front columns, may be inserted into the area between the baseplates and the movable clamping platen, and removed again. This means that better use can be made of the pressure and pressing capacity of the press, while the press is similarly or comparably simple, stable and compact in design and as advantageous for production and maintenance as conventional presses with columns arranged in a rectangle.
