Abstract: A shaping mold of a bushing base includes a bottom die and a core integrally made of a heat-resistant plastic material. A cavity in a predetermined shape is formed at the bottom die and provided for accommodating the core with an appropriate predetermined gap, such that the core and the cavity can be engaged or disengaged with one another by turning. A low-temperature shaping material such as silicone or polyurethane (PU) foam is injected into the gap between the cavity and the core for integrally forming the bushing base in a predetermined shape. The invention can lower the cost of the shaping mold of the bushing base significantly, and provide a smooth fine surface of the molded bushing base.

Abstract: A shaping mold of an air filter includes an upper mold base and a lower mold base, and a filter material having a corresponding shape is placed and fixed at a partition plate of the lower mold base to reduce manufacturing time and material cost of the mold, and also achieve the effects of providing a higher precision of positioning the filter material and improving the production efficiency, quality and reliability of the product.
