Injection Nozzle Positioning Mechanism for Multi-Plane Mold Filling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional injection apparatuses are limited in their ability to adjust the relative positions of multiple injection nozzles, which restricts the design of molds with material-filling apertures not on the same horizontal plane, leading to suboptimal mold structures and inefficient material filling.
Innovation Solution
A mechanism with a guide section and two injection sections, where each section is slidably mounted on the guide section to move along the X-axis and vertically along the Y-axis, allowing independent adjustment of nozzle positions to match the mold's material-filling apertures, enabling flexible material filling without the need to wash out or replace materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the injection nozzles are synchronously moved along Y-axis to maintain constant space between them, then the structural simplicity is maintained, but the adaptability to molds with material-filling apertures not on the same horizontal plane is lost
Solution Approach 1:
The patent applies the dynamics principle by making the second injection section vertically movable within a predetermined range of height along the Y-axis, while the first injection section remains fixed in the vertical direction. This creates a dynamic system where the relative vertical position between injection nozzles can be adjusted to match material-filling apertures at different heights in the mold, resolving the contradiction between maintaining structural simplicity and achieving adaptability to various mold configurations.
2Ease of manufacture
If the material-filling apertures are designed to be on the same horizontal plane, then the injection nozzle positioning is simplified, but the mold design flexibility and optimality are reduced
Solution Approach 1:
The patent resolves this contradiction by enabling vertical movement of the second injection section along the Y-axis within a predetermined height range. This dynamic adjustment capability allows the injection nozzles to reach material-filling apertures at different vertical positions in the mold, thereby maintaining ease of nozzle positioning while simultaneously providing mold design flexibility and avoiding the need for elongated pouring channels or suboptimal mold structures.
3Productivity
If the relative positions of injection nozzles are fixed, then the mechanism structure is simplified, but the ability to quickly switch material filling positions is lost
Solution Approach 1:
The patent applies the dynamics principle by providing a vertical movement mechanism for the second injection section that allows quick adjustment of the relative vertical position between injection nozzles. This enables rapid switching of material filling positions without requiring complete mechanism replacement or complex multi-axis movement systems, thereby improving productivity while maintaining reasonable device complexity.
Solution Approach 2:
The patent segments the injection apparatus into two independently controllable injection sections: the first injection section with fixed vertical position and the second injection section with adjustable vertical position. This segmentation allows the vertically movable second section to quickly switch between different height positions for filling apertures at various levels, enhancing productivity without requiring the entire system to be reconfigured.

AI summary
A mechanism for adjusting relative positions of multiple injection nozzles of an injection apparatus. The mechanism includes a guide section serving as a rail horizontally extending in a predetermined direction; a first injection section having at least one injection nozzle and slidably disposed on the rail, whereby the first injection section is guidable by the rail to horizontally move along X-axis defined by the rail; and a second injection section having at least one injection nozzle and slidably disposed on the rail. The second injection section is spaced from the first injection section by a distance and guidable by the rail to horizontally move along X-axis defined by the rail. The second injection section is further vertically movable within a predetermined range of height along Y-axis normal to X-axis.
