Problems solved by technology

[0002] At present, most of the filter plate pressing is plasticized by the screw and extruded into the insulation barrel. After weighing, it is manually transferred to the mold and then molded. The biggest defect of this process is: first, the single-screw plasticizing temperature is too high, and the material performance is greatly lost. ; Second, the insulation effect of the material tank is not ideal, and the temperature is uneven; third, the moving process of the material tank takes a long time, which takes a few minutes; fourth, the filter plate is cold and has many pores; Sixth, the strength and quality of the filter plate are fixed; Seventh, the degree of automation is low and the production cycle is long, especially for large-scale filter plates

Embodiment 1

[0010] Embodiment 1: with reference to attached figure 1 . New plastic filter plate or plate forming process, the hot runner port of the hot runner plastic filter plate forming mold or hot runner plate forming mold is located on the upper or bottom or side of the hot runner plastic filter plate forming mold or hot runner plate forming mold, the injection molding machine The outlet of the injection molding mechanism is aligned with the hot runner mouth. After the plastic raw material is heated and plasticized by the injection molding mechanism, the outlet is injected into the cavity of the mold through the hot runner in the hot runner plastic filter plate forming mold or the hot runner plate forming mold. , After cooling and shaping, the mold can be opened to take out the filter plate or plate. When the hot runner opening of the hot runner plastic filter plate forming mold or the hot runner plate forming mold is located on the upper part of the forming mold, the outlet of the ...

Embodiment 2

[0011] Embodiment 2: Novel plastic filter plate or plate molding process, the hot runner mouth of the hot runner plastic filter plate forming mold or the hot runner plate forming mold is located at the top or bottom or side of the hot runner plastic filter plate forming mold or the hot runner plate forming mold , the discharge port of the injection molding mechanism is aligned with the hot runner port, and the hydraulic press is closed. After the plastic raw material is heated and plasticized by the injection molding device, the discharge port is injected into the mold through the hot runner in the hot runner plastic filter plate forming mold or the hot runner plate forming mold. After forming in the cavity, cooling and setting, the hydraulic press can open the mold to take out the filter plate or plate. The filter plate or plate forming mold is located in the hydraulic press and is clamped and opened by the hydraulic press. The hot runner device is located on the upper or bott...

Abstract

A process for preparing the plastic filter plate or plastic plate features that its mould is controlled by hydraulic press, its heat channel is positioned at the bottom of lower mould and communicated with said lower mould, and the plasticized plastics is injected in said mould via heat channel.

Description

Technical field: [0001] The invention relates to a forming process of a filter plate of a filter press, which belongs to the field of filter plate manufacturing of a filter press. Background technique: [0002] At present, most of the filter plate pressing is plasticized by the screw and extruded into the insulation barrel. After weighing, it is manually transferred to the mold and then molded. The biggest defect of this process is: first, the single-screw plasticizing temperature is too high, and the material performance is greatly lost. ; Second, the insulation effect of the material tank is not ideal, and the temperature is uneven; third, the moving process of the material tank takes a long time, which takes a few minutes; fourth, the filter plate is cold and has many pores; Sixth, the strength and quality of the filter plate are not changed; Seventh, the degree of automation is low and the production cycle is long, especially for large-size filter plates. Invention con...
