Description

Technical Field

[0001] This utility model relates to the field of demolding structure technology, specifically a silicone mold drag demolding structure. Background Technology

[0002] The silicone mold pull-out demolding structure is a commonly used structure in mold design, primarily for demolding operations. This structure combines the excellent elasticity and plasticity of silicone material, allowing the mold to easily and quickly detach from the product after molding. The silicone mold pull-out demolding structure refers to a structure that uses a pulling motion to create relative movement between the mold and the product, thereby enabling the product to smoothly eject from the mold. This structure is widely used in the manufacturing industry for various silicone products. The silicone mold pull-out demolding structure mainly includes components such as the mold core, cavity, pull plate, pull rod, and spring. Among these, the pull plate and pull rod are the core components; by pulling these components, the mold moves, thus achieving product demolding.

[0003] When using existing equipment, the mold needs to be cleaned and maintained regularly, otherwise it will affect its service life and demolding effect. Cleaning the mold is troublesome and wastes manpower and time. At the same time, silicone molds are prone to sticking to the product surface during demolding, especially when the mold surface is not adequately treated or the release agent is used improperly. Therefore, we need to propose a silicone mold drag demolding structure. Utility Model Content

When the connecting frame, fixed frame, and moving frame move, they fit together to form a complete molding cavity. The position of the moving frame is adjusted by a handle. When the moving frame moves closer to the fixed frame, it positions the two connecting frames. When the moving frame moves in the opposite direction to the fixed frame, the multiple molding half-blocks can be separated, making it easy to remove the product from inside the molding half-blocks. The fixed frame is fixed by a positioning pin and a first fixing bolt. When the connecting frame and the moving frame move, a guide rail and a guide rod guide them, thus solving the problems mentioned in the background art.
