20240042659 · 2024-02-08 · ·

A molding tool includes a top die, a bottom die, and several middle dies. Each middle die has a molding hole. The top die or the bottom die has a core, and the other one has a partial cavity. The partial cavity and each molding hole jointly form a cavity matching the core. The top die is opposite to the bottom die. The top die and/or the bottom die are/is driven to move towards or away from each other. Each middle die is moved to a position between the top die and the bottom die, allowing each middle die to be clamped with the top die and the bottom die. Upon using, a raw material is disposed on each middle die before the middle dies being sequentially moved to the position, making the top die, the bottom die, and the middle die clamp to process the raw material into a product.
