Description

Technical Field

[0001] The utility model relates to the technical field of multi-cone filter processing, in particular to an injection mold which is convenient for taking products out of a mold cavity. Background Art

[0002] The multi-cone filter is a commonly used filtering equipment, mainly used to remove impurities and solid particles from liquids or gases. It adopts a conical structure, and uses a filter screen to intercept impurities and solid particles inside the equipment, allowing the fluid to pass smoothly. The multi-cone filter consists of a filter screen, a filter cartridge, and inlet and outlet pipes. When the fluid passes through the filter screen, the solid particles will be intercepted by the filter screen, and the pure fluid will be discharged through the outlet pipe. This filter has a wide range of applications in many fields. For example, in the industrial field, it is often used in liquid processing, chemical production, water treatment and other processes. Multi-cone filters are generally manufactured using injection molds in production and processing.

[0003] In the production process, multi-cone filters are generally produced by injection molding using injection molds. After the injection molded parts are cooled and formed inside the mold, they are generally pushed out of the mold using an ejector structure. Although this structure is relatively convenient, the metal demoulding structure may affect the surface structural appearance of the multi-cone filter injection molded parts.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an injection mold that is convenient for removing the product from the cavity is proposed. Utility Model Content
