The present invention provides a molding die for preparing
candle wicks, which is applied to the field of molding dies. The molding die surrounds and assembles a plurality of
metal strips with convex middle parts. By pulling down the
metal strips, they are assembled to form a cylindrical molding cavity. After the
candle wick is cast and molded, by releasing the
metal strips, the middle parts of the
metal strips can be reset and automatically separated from the outer end wall of the molded
candle wick, weakening the clamping force of the molding cavity on the side wall of the
candle wick, thereby ensuring the stability of the
candle wick when it is pushed up and demolded, avoiding the
extrusion force being concentrated at the bottom of the
candle wick and causing its compression deformation, which is beneficial to improving the product qualification rate. At the same time, a sleeve is provided, which can be sleeved on the outside of the plurality of
metal strips after being lifted, restricting the outside of the molding cavity formed by the plurality of
metal strips, further ensuring the tight fit when the plurality of metal strips are stretched and assembled, and ensuring the stability of the equipment when
casting and molding the candle wick to a certain extent.
