Description

Technical Field

[0001] The invention relates to the technical field of injection molding, in particular to an injection molding mold for producing a plastic diaphragm filter plate. Background Art

[0002] The filter plate of the filter press is a combination of a diaphragm filter plate and a chamber filter plate. The chamber filter plate is a solid structure, and the diaphragm filter plate is composed of a diaphragm and a core plate to form an internal chamber structure. The diaphragm filter plate is composed of two diaphragms and a core plate. The external medium (water or compressed air, etc.) is introduced into the chamber between the core plate and the diaphragm, causing the diaphragm to swell and compress the filter chamber composed of the diaphragm filter plate and the chamber filter plate, thereby achieving better separation and increasing the solid content. The diaphragm is the main moving part, and the folding movement can easily cause the diaphragm to deform and then be damaged. The diaphragm of the rubber diaphragm filter plate is generally embedded in the groove of the core plate, which is easy to disassemble and replace, because the rubber diaphragm has high elasticity and is not easily damaged.

[0003] At present, when the existing plastic diaphragm filter plate is injection molded, the material needs to be introduced into the molding mold. During the injection molding process, the plastic material needs to be injected and filled through the material guide structure.
