Split Mold Structure for Grit-Textured Bottle Demolding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing production molds struggle to demold split-type grit-textured packaging bottles without damaging the anti-slip texture, and the cap can displace relative to the mold core during opening, leading to deformation and incomplete separation.
Innovation Solution
A production mold comprising a fixed and movable mold assembly with a pushing assembly, utilizing an inverted cone structure on the mold core and guided sliders to stabilize the product, ensuring smooth demolding by using inclined guide pillars and a pushing mechanism to prevent displacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If an existing mold is used to demold the split-type grit-textured packaging bottle, then the bottle can be produced, but the anti-slip grit texture structure is damaged and the cap displaces relative to the mold core
Solution Approach 1:
The mold is divided into a fixed mold assembly and a movable mold assembly that can separate from each other. The fixed mold assembly includes a fixed mold A plate with a fixed mold insert, while the movable mold assembly includes a movable mold B plate with a movable mold insert. This segmentation allows the mold to open cleanly without damaging the grit texture or causing cap displacement.
Solution Approach 2:
A pushing assembly with a movable mold push plate is introduced as an intermediary mechanism. This push plate, driven by side sliders, gently pushes the cap off the mold core during demolding, preventing direct contact between the mold core and the grit texture that would cause damage.
2Productivity
If external force is applied to separate the cap and upper bottle body, then the products can be taken out, but the snap-fitting portion of the cap is stretched/damaged and deformed
Solution Approach 1:
The mold is designed with a pushing assembly that performs the separation action in a controlled preliminary manner. The movable mold push plate, driven by side sliders, gradually pushes the cap away from the mold core before the cap and upper bottle body are fully separated, preventing sudden stress that would cause deformation.
Solution Approach 2:
The mold incorporates dynamic elements including a movable mold push plate that can move along the mold core, and side sliders that can move to drive the pushing action. This dynamic design allows the demolding process to adapt to the specific geometry of the cap and bottle body, ensuring clean separation without damage.

AI summary
A production mold for a split-type grit-textured packaging bottle includes fixed-mold and movable-mold assemblies. The fixed-mold assembly has top and bottom provided with injection channel and fixed-mold A plate respectively. Fixed-mold insert(s) installed in the fixed-mold A plate communicates with the injection channel, and corresponds to a concave cavity having bottom consistent with product's closed end in shape. Two inclined guide pillars are provided the concave cavity's two sides. The movable-mold assembly's top has a movable-mold B plate provided with a B-plate insert with a concave cavity-facing mold core. The B-plate insert's end relative to the product forms internally as an inverted cone structure. A pushing assembly includes a movable-mold push plate movable on the movable-mold B plate and having a top provided, relative to the concave cavity, with side sliders for correspondingly driving the guide pillars. Sliders'product-facing sides have structures matching grit texture on the product's outer wall.
