Problems solved by technology

However, the existing manufacturing method of using molds to produce flanges is relatively inefficient, and the molding quality and anti-aging performance of the manufactured small flanges need to be improved
[0003] like figure 1 As shown, there are the following problems in the injection molding of small flanged plastic products: 1) The product is relatively small and round, and it is difficult to cool the molded part, resulting in uneven deformation of the product and a high rate of product rejection; Trapezoidal thread feature, difficult demoulding; 3) The wall thickness of the product is thicker, and the tightness to the core is relatively large, so it is difficult to eject and demould; 4) During injection molding, the position of the gate is off-center and the injection molding is likely to cause the final molding of the product to warp Big deformation

Abstract

The invention provides a sewage treatment device and a manufacturing method thereof. The sewage treatment device comprises a sprue bush, a positioning ring, a front mold drawing rod, a panel, a runnerplate front drawing rod, a runner plate, a runner plate embedding part, a front mold plate, a front mold embedding part and the like. A flange cover manufactured by the mold has the advantages that the forming precision, structure strength, deformation control, sealing property and anti-aging property are greatly improved; furthermore, the quality and production efficiency of the sewage treatmentdevice are ensured.

Description

technical field [0001] The invention relates to the design field of sewage treatment, in particular to a sewage treatment device and a manufacturing method thereof. Background technique [0002] In the fields of new energy vehicles, sewage treatment, and medical equipment, flange covers have been widely used, especially in sewage treatment devices. However, the existing manufacturing method of using molds to produce flanges is relatively inefficient, and the molding quality and anti-aging performance of the manufactured small flanges need to be improved [0003] Such as figure 1 As shown, there are the following problems in the injection molding of small flanged plastic products: 1) The product is relatively small and round, and it is difficult to cool the molded part, resulting in uneven deformation of the product and a high rate of product rejection; Trapezoidal thread feature, difficult demoulding; 3) The wall thickness of the product is thicker, and the tightness to th...
