A Three-Piece Collapsible Mold is a type of mold used in manufacturing and molding processes, particularly for creating complex or hollow parts. It consists of three separate sections that can collapse or retract, allowing for easier removal of the molded part without causing damage.

Three-Piece Collapsible Mold is a special mold used for injection molding, consisting of three parts: upper mold, lower mold and middle mold. This mold design allows a portion of the mold to be folded for easier release from the molded part. Typically used to produce parts with internal structures, such as holes or hollow parts. Its design can reduce damage to molded parts and improve production efficiency. Three-piece foldable molds are widely used in industries such as plastic products, medical devices, and electronic products.

Working Principle

Working Principle
The working principle of the Three-Piece Collapsible Mold is based on its unique construction design. The mold consists of an upper mold, a lower mold, and an intermediate mold, which can be collapsed with either the upper or lower mold. During the injection molding process, the mold is first closed and the upper and lower molds are clamped together to fill the mold cavity with injected plastic. When the molding cycle is complete, the middle mold is folded, allowing a portion of the molded part to be easily removed from the mold without excessive force. This folding design greatly simplifies the process of removing the molded part, improves ease and safety of operation, and reduces damage to the molded part. This type of mold is suitable for the production of parts that require complex internal structures, bringing convenience and efficiency to the production process.
