Self-cleaning device for gypsum hollow block mould

Abstract

The invention discloses a self-cleaning device for a gypsum hollow block mould. A mounting plate is horizontally arranged on a hollow base; two transverse side plates and two longitudinal end plates are connected through fasteners to define a square cylinder; the cylinder is located on the mounting plate; N longitudinal spacer plates are arranged in the cylinder to divide the inner cavity into N+1 cavities, wherein N is a natural number not less than 2; the lower end of each cavity is in sliding fit with a horizontal bottom plate; multiple evacuation rods are longitudinally inserted into each bottom plate at intervals; the lower end of each evacuation rod is provided with an external thread and connected with the mounting plate through a fastener; the lower side of each bottom plate is connected with two ejector rods which are longitudinally arranged, extend downwards and penetrate through the mounting plate; each evacuation rod and the corresponding bottom plate are sealed through at least one O-shaped seal ring; and each bottom plate and the wall of the corresponding cavity are sealed through a square seal ring. By adopting the device, abrasion is relatively low even if the mould using time is relatively long, and a small amount of leaked gypsum slurry can be automatically cleaned in the mould using process, thereby realizing the self cleaning of the mould; and the mould has relatively good sealing performance, thereby obtaining relatively high surface finish quality of the finished gypsum hollow block product and reducing the rejection rate.

Description

technical field [0001] The invention relates to a self-cleaning device for a gypsum hollow block mold. Background technique [0002] Gypsum hollow block is one of the green and environmentally friendly building materials that my country has vigorously promoted in recent years. For gypsum hollow blocks, there are not only certain mechanical performance requirements, but also strict requirements for its size, precision and surface smoothness. [0003] At present, the equipment for producing gypsum hollow blocks in China is divided into two categories according to the different ways of releasing the gypsum hollow blocks: one is the open mode, and the other is the extrusion ejection type. [0004] The open mode is mainly used in manual production or simple mechanized production. It has high labor intensity, low production efficiency, poor product quality, and unstable product quality. It has been listed as the scope of elimination by the Ministry of Construction. [0005] The ...

AI Technical Summary

Problems solved by technology

Since the sealing between each evacuating rod and the corresponding bottom plate, and between each bottom plate and the cavity wall of the corresponding cavity is only guaranteed by machining accuracy, even if the mold is used for a short period of time, it will have the defect of greater wear and tear. A large number of slurry leakage, difficult to clean and other problems occurred, and the sealing performance of the mold was poor, which led to severe sticking of the gypsum mold, the surface finish of the finished gypsum hollow block was getting lower and lower, and the scrap rate increased
