Multi-step vacuum filtration plate base

Abstract

A multi-step vacuum filtration plate base belongs to the technical field of design of molds. The upper end of a base body an opening end, and an exhaust hole is integrally formed in the lower end of the base body. The multi-step vacuum filtration plate base is characterized in that at least two groups of filter plate bases in upper and lower arrangement are located in the center of the base body; the diameter of one filter plate base close to the upper end of the base body is greater than that of another filter plate base far from the upper end of the base body; ring-shaped sealing grooves are respectively formed in the sections of the base body, which are located on the peripheries of the filter plate bases; and the lower end of the filter plate base at the bottommost end of the base body is communicated with the exhaust hole. According to the multi-step vacuum filtration plate base, corresponding and matched filter plates with different sizes can be placed on the different filter plate bases, and the filter plate bases can be respectively used for producing heat insulation barrels with different sizes through being matched with internal / external molds with different sizes, so that the defect of single function of the conventional filter plate base is overcome, and the functions of the multi-step vacuum filtration plate base are greatly increased.

Description

technical field [0001] The invention belongs to the technical field of mold design, and in particular relates to a mold-type tool for preparing chopped carbon fiber insulation cylinders by a vacuum suction filtration method. Background technique [0002] The mold of chopped carbon fiber insulation cylinder prepared by vacuum filtration method is mainly composed of inner and outer molds, filter plate, filter plate seat, water storage device and vacuum pump. Traditional filter plate holders can only be installed with corresponding filter plates to produce insulation sleeves of the same size. In actual production, insulation sleeves of different sizes must be equipped with different filter plate holders, requiring multiple sets of molds, which greatly reduces production efficiency. The function of the filter plate seat is single, and the mold is increased, which increases the production cost and is unfavorable for industrialized production. [0003] At present, there is no...

AI Technical Summary

Problems solved by technology

[0006] In the present invention, a plurality of filter plate holders in the shape of steps are arranged in one seat, which greatly enhances its practicability. Correspondingly matched filter plates of different sizes can be placed on different filter plate holders, and then matched with different sizes. The internal and external molds can be used to produce insulation cylinders of different sizes, which improves the defect of single function of the traditional filter plate seat and greatly enhances its function
