Filter screen assembly production method and injection molding device

Abstract

The invention relates to a filter screen assembly production method and an injection molding device. The method comprises the following steps: 1, the injection molding device is provided, the injection molding device comprises an upper die and a lower die which are oppositely arranged, the lower die is provided with a boss, and the upper die is provided with a groove corresponding to the boss; 2,a filter screen is placed on the boss; 3, the upper die and the lower die are closed, the boss is arranged in the groove in an accommodated mode, the upper die and the lower die are closed to form a die closing cavity, and the boss is arranged in the die closing cavity; 4, sizing material is injected into the die closing cavity, so that the sizing material is connected with the filter screen; and5, after the sizing material is formed, the upper die and the lower die are opened, and a plastic shell formed with the filter screen by injection molding is taken out. By placing the filter screen inthe injection molding device to carry out injection molding together with the plastic shell, the filter screen can be directly connected with the plastic shell, the connection between the filter screen and the plastic shell is more stable, the subsequent cutting of the filter screen is avoided, and the installation of the filter screen and the plastic shell is simpler and more convenient.

Description

technical field [0001] The invention relates to the technical field of injection molding, in particular to a production method of a filter screen assembly and an injection molding device. Background technique [0002] The sweeping robot sucks the dust and garbage on the ground through the suction device. In order to isolate garbage and other debris and prevent the debris from entering the suction device, it is necessary to install a filter assembly in the suction chamber of the sweeping robot. The filter assembly includes a filter and a plastic shell, the filter screen is installed on the plastic shell. In order to produce the filter screen assembly, the plastic shell needs to be injection-molded first, then the filter screen is cut according to the shape of the plastic shell, and then the filter screen is installed on the plastic shell. In the process of installing the filter screen on the plastic shell, the filter screen cannot be firmly installed on the filter screen due...

AI Technical Summary

Problems solved by technology

In the process of installing the filter screen on the plastic shell, the filter screen cannot be firmly installed on the filter screen due to the low cutting precision of the filter screen, resulting in a gap between the filter screen and the plastic shell or warping of the filter screen. Lead to poor filtering effect, in addition, the installation process is more complicated and consumes more manpower
