Slide-Block Mold Structure for Plastic Pallet Reinforcement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional plastic pallet manufacturing techniques face challenges with non-uniform stress distribution and structural damage due to ribs arranged in a single direction, leading to increased manufacturing costs and longer mold extraction times, especially when creating lateral openings and inner through holes.
Innovation Solution
The introduction of a slide-block module structure on the plastic pallet shaping mold, where ribs are arranged transversely and longitudinally, with fixed and sliding blocks that form a mold cavity for injection shaping, allowing for oblique sliding to facilitate smooth mold release and reduce extraction time and costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If ribs are arranged in a single direction for manufacturing convenience, then manufacturing is easier, but stress distribution becomes non-uniform and structural damage occurs
Solution Approach 1:
The rib structure is segmented into multiple groups arranged in different directions (transverse and longitudinal). Each group of ribs is independently formed by slide blocks, allowing the structure to distribute stresses more uniformly across the bearing surface while maintaining manufacturing feasibility through modular formation processes.
2Ease of manufacture
If lateral openings and inner through holes are created using conventional slide blocks, then openings are formed, but mold extraction time increases and manufacturing cost rises
Solution Approach 1:
The slide blocks are designed with dynamic movement capabilities, allowing them to slide along guiding portions during the molding process. This dynamic adjustment enables the slide blocks to efficiently form lateral openings and inner through holes while facilitating smoother mold extraction, thereby reducing extraction time and costs.
Solution Approach 2:
The slide blocks operate in multiple dimensional directions simultaneously - forming openings laterally while also creating vertical through holes. This multi-dimensional approach allows a single slide block mechanism to accomplish what would traditionally require multiple separate operations, reducing overall manufacturing time and cost.
3Ease of manufacture
If slide block length is increased to form openings, then opening formation is achieved, but mold manufacturing difficulty increases and extraction cost rises
Solution Approach 1:
The slide block mechanism is segmented into modular components including fixed blocks, sliding blocks, and guiding portions. This segmentation allows each component to be designed and manufactured independently, reducing the overall complexity of the mold while maintaining the capability to form lateral openings and inner through holes effectively.

AI summary
The structure of slide-block module includes a plurality of slide-block modules composing several reinforced areas, the slide-block modules are contained in a plastic pallet shaping mold, the plastic pallet is provided in a connecting zone between a central area of a bearing surface and a plurality of supporting columns at surrounding sides on the plastic pallet with the plurality of reinforced areas having ribs arranged transversely or longitudinally; each slide-block module includes a fixed block fixed on a shaping mold and having at least a lateral side beveled, and having a slide block, by obliquely sliding moving of the slide block on the fixed block, the slide block can be released along the lateral side of the fixed block from the mold smoothly after injection molding.
