Inclined Wall Material Supply Device for Injection Molding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing material supply mechanisms in injection molding devices often experience supply failures due to material accumulation between rotation members and housing, leading to hindered rotation and potential clogging.
Innovation Solution
A material supply device with an inclined housing wall that reduces the accommodation space volume downward, featuring a rotation mechanism that overlaps the inclined wall and intermittently supplies material, preventing direct load application on the rotation member and reducing the risk of clogging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a rotation member is used to supply material intermittently, then material supply control is improved, but material accumulation between the rotation member and housing causes rotation hindrance and supply failure
Solution Approach 1:
An inclined wall is introduced as an intermediary element between the material accommodation space and the rotation member. This inclined wall prevents material from accumulating in the gap between the rotation member and housing, thereby eliminating the root cause of rotation hindrance while preserving the intermittent supply function of the rotation member.
Solution Approach 2:
The housing internal space is segmented into distinct functional zones: a material accommodation space, an inclined wall region, and a material supply region. This segmentation prevents material from freely moving into areas where it could cause interference with the rotation member, thus maintaining reliable operation.
2Quantity of substance
If material is accumulated in the housing for continuous supply, then material availability is improved, but load on the rotation mechanism increases causing operation failure
Solution Approach 1:
The inclined wall extracts or removes the problematic gap space between the rotation member and housing where material accumulation occurs. By eliminating this space, the design maintains material availability through the rotation mechanism's intermittent supply function while preventing excessive load accumulation that would hinder rotation.
3Stability of the object's composition
If the rotation member contacts the housing wall for support, then structural stability is improved, but material enters the contact area causing clogging and rotation hindrance
Solution Approach 1:
The inclined wall creates a localized quality change in the housing structure, forming a smooth transition surface that directs material flow away from the rotation member-housing interface. This local modification prevents clogging at the critical interface while maintaining overall structural stability through the inclined wall's support function.

AI summary
In a material supply device for supplying a material to a plasticizing unit that plasticizes the material to generate a plasticized material, the material supply device includes: a housing having an inlet through which the material is fed into the plasticizing unit, and configured to accommodate the material; and a supply mechanism provided in the housing, positioned above the inlet, and configured to intermittently supply the material to the inlet. The housing has an inclined wall that defines an accommodation space for the material above the supply mechanism and is inclined such that a volume of the accommodation space is reduced downward, and the supply mechanism at least partially overlaps the inclined wall when viewed from a vertical direction.
