Demoulding structure used for producing brush strip of dust collector

Abstract

A demoulding structure used for producing a brush strip of a dust collector comprises a fixing board, a bearing pedestal and a sliding block which are sequentially arranged from front to back; a bearing is installed inside the bearing pedestal; a cylindrical cavity is arranged in the bearing in a penetrating mode; the front end of the cavity extends out of the fixing board; the rear end of the cavity is fixedly connected with the sliding block; an ejection block is arranged behind the sliding block and forwards provided with an ejection rod used for ejecting the brush strip of the dust collector; the front end of the ejection rod extends into the cavity; the cavity is sleeved with a roller; the roller is provided with a spiral groove matched with the brush strip of the dust collector; the fixing board is provided with a guide block matched with the spiral groove; and the sliding block is moved backwards, the roller drives the cavity to move backwards spirally, and the ejection rod ejects the brush strip of the dust collector out of the cavity. Through cooperation of the spiral groove in the roller and the guide block, the spiral demoulding structure is formed, the brush strip of the dust collector is rapidly and completely released from a mould, the mold manufacturing cost is lower, the demoulding speed is higher, and the production efficiency is higher.

Description

technical field [0001] The invention relates to a stripping structure for producing brush strips for vacuum cleaners. Background technique [0002] The vacuum cleaner uses a motor to drive the blades to rotate at a high speed, generating negative air pressure in the sealed bag housing, and then absorbs the dust through the floor brush and hose. The vacuum cleaner can be used on floors of different materials, such as carpets and floor tiles. [0003] The brush bar is an important component of the floor brush of the vacuum cleaner. The brush strips are generally provided with ribs and grooves, and are distributed in a spiral shape, which can allow the vacuum cleaner to inhale more air during use, reduce dead angles during cleaning, and greatly improve cleaning ability and cleaning efficiency. [0004] Because the brush strip has a spiral structure, it causes great difficulties in the injection molding of the mold, especially in demoulding, and a slight deviation will lead to ...

AI Technical Summary

Problems solved by technology

[0004] Due to the spiral structure of the brush bar, it has caused great difficulties in the injection molding of the mold, especially in the demoulding process, and a slight deviation will lead to the scrapping of the product

In order to solve the demoulding problem, the existing molds generally use a split cavity, which can slightly improve the pass rate, but this will lengthen the demoulding time and greatly reduce the production efficiency
