Insert Molding Apparatus Fixing Reinforcement Position
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In insert molding processes for roof racks, the molding position of reinforcement members can be disrupted by the flow of moldable materials or external impacts, leading to increased insert defect rates.
Innovation Solution
An insert molding apparatus featuring a lower mold with a seating part for an insert member, an upper mold, a first fixing part with a first head that is inserted into the insert member's through-hole, and a first drive unit to adjust the first head's insertion length, ensuring the insert member is effectively fixed during the molding process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the insert member is placed on the seating part during insert molding, then the molding process can be performed, but the molding position may be changed due to material flow or external impact, increasing insert defect rate
Solution Approach 1:
The first head is inserted into the through-hole of the insert member before the molding process begins, and the first drive unit adjusts the insertion length to a predetermined position. This preliminary positioning action ensures that the insert member is securely fixed at the correct location before material injection, preventing position shifts during molding and reducing insert defects.
Solution Approach 2:
The first head acts as an intermediary component that mediates between the insert member and the molding apparatus. By inserting the first head into the through-hole and adjusting its position, it provides a stable reference point that prevents the insert member from shifting due to material flow or external impacts during the molding process.
2Manufacturing precision
If a fixing mechanism is added to secure the insert member, then positioning accuracy improves, but device complexity increases
Solution Approach 1:
The first head serves multiple functions: it acts as a positioning element by being inserted into the through-hole, serves as a fixing mechanism through its adjustable insertion length, and provides structural support during molding. This multi-functionality reduces the need for separate dedicated fixing components, thereby limiting the increase in device complexity while maintaining positioning accuracy.

AI summary
An insert molding apparatus includes: a lower mold including a seating part on which an insert member including a through-hole is seated; an upper mold mounted on the lower mold to receive the insert member seated on the seating part; and a first fixing part including a first head provided in the lower mold and inserted into the through-hole of the insert member when the insert member is seated, and a first drive unit that moves the first head. The first drive unit is moved to adjust a length by which the first head is inserted into the through-hole.
