Abstract

The invention relates to a structure of directly molding the membrane injection moulding on the filter pan and its molding method, it includes filter core, a filter core is put into the mould, directly injecting- moulding the fusion plastic on the one face or two faces or all faces of the filter core, and composing the membrane or membrane filter or filter pan. The merit: First, founding new structure and the new method in the filter board core directly; second, injection moulding the membrane and the filter pan, avoid drilling, two order scraps, bevel edge, deburring and so on crafts, saving the labor,and time,and has high efficiency, and the fitting grade and the seal reliability of the two reached to 100% initiated; third, realizing the ultra-thin, flexibility of the membrane thickness; fourth, using the release agent and anti-tack coat as the mold core of tympanic membrane squeezing cavity.

Description

technical field

[0001] The invention relates to a structure and a molding method for direct injection molding of a diaphragm on the core surface of a filter plate, belonging to the field of diaphragm and filter plate manufacturing. Background technique

[0002] 1. Injection molding process of filter plate: The applicant’s invention patent number is 200410037113.5, titled "New Plastic Filter Plate or Plate Forming Process", the new plastic filter plate or plate forming process, hot runner plastic filter plate forming mold or hot runner The hot runner opening of the plate forming mold is located on the upper or bottom or side of the hot runner plastic filter plate forming mold or the hot runner plate forming mold. The outlet of the injection mechanism of the injection molding machine is aligned with the hot runner opening, and the plastic raw material is heated and plasticized by the injection molding mechanism. Finally, the discharge port is injected into the cavity of the mo...
