Molding Head Guide Protrusion for Shaping Hole Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Molding heads in existing technologies face challenges in forming molding pieces with high accuracy, especially for shaping holes that are far from the discharge hole or have complex shapes like long, sharply curved holes, as they struggle to maintain shape and posture consistency.
Innovation Solution
The introduction of a guide protrusion portion in the molding head's outer casing unit, which directs the content flowing into the dispersion chamber to collide with guide surfaces and protrusions, ensuring accurate shaping and orientation of molding pieces regardless of the distance or shape of the shaping holes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If shaping holes are enlarged to improve content flow, then productivity increases, but manufacturing precision deteriorates because molding pieces cannot maintain desired shape and posture on the molding surface
Solution Approach 1:
The guide protrusion portion is strategically positioned within the dispersion chamber to provide localized guidance only where needed. This localized intervention allows the shaping holes to maintain their enlarged cross-sections for productivity while the guide protrusion ensures proper content direction and molding piece formation accuracy at critical locations.
Solution Approach 2:
The guide protrusion portion acts as an intermediary element between the dispersion chamber and the shaping holes. It mediates the content flow by guiding it toward the shaping hole openings, enabling both enlarged hole dimensions for productivity and precise molding piece formation for accuracy.
2Adaptability or versatility
If shaping holes are made long and sharply curved to achieve complex molded article forms, then adaptability increases, but manufacturing precision deteriorates due to difficulty in forming accurate molding pieces
Solution Approach 1:
The guide protrusion portion performs preliminary action by directing the content toward the shaping hole openings before the content enters the long, sharply curved shaping holes. This preliminary guidance ensures that even complex-shaped molding pieces are formed with high accuracy by properly orienting the content flow at the entrance of difficult-to-reach shaping holes.
3Adaptability or versatility
If shaping holes are positioned far from the discharge hole to increase dispersion coverage, then adaptability increases, but manufacturing precision deteriorates due to difficulty in forming accurate molding pieces
Solution Approach 1:
The guide protrusion portion serves as an intermediary that bridges the distance between the discharge hole and distant shaping holes. By positioning the guide protrusion within the dispersion chamber, it extends the guidance function to distant locations, ensuring that even shaping holes far from the discharge hole receive properly directed content for accurate molding piece formation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution allows for the formation of molding pieces with high accuracy and adjustable forms, even with complex shaping holes, by ensuring precise introduction and orientation of the content, resulting in varied and accurately formed molded articles.
Implementation Method 1
a guide protrusion portion, which introduces a content flowing into a dispersion chamber to openings of shaping holes on a molding surface side
Implementation Method 2
a content which has flowed into the dispersion chamber through the discharge hole can be introduced to the openings of the shaping holes on the molding surface side by causing the content to collide with the guide protrusion portion

AI summary
A molding head (10) includes: an outer casing unit (15) that has a top wall portion (24) which is installed above a discharge hole (19a) for discharging a content and in which a plurality of shaping holes (26) penetrated in a vertical direction are formed, and that causes a molding surface (26) of the top wall portion to discharge the content which has passed through the shaping holes, the molding surface being directed upward; and an inner plate (16) that is disposed inside the outer casing unit and defines, between the inner plate and a supply surface (28) of the top wall portion, a dispersion chamber which disperses the content from the discharge hole in a radial direction along the molding surface and supplies the content to the shaping holes, the supply surface being directed downward, in which the molding head forms a molded article on the molding surface by combining a plurality of molding pieces formed by the content from the dispersion chamber passing through the plurality of shaping holes, and a guide protrusion portion (40) with which the content collides to be introduced to openings of the shaping holes on the molding surface side is formed on at least one of inner surfaces of the plurality of shaping holes, or in at least one of circumferential opening edge portions of the plurality of shaping holes on the supply surface side.
