Charging and scraping device used for annular mould

Abstract

The invention discloses a charging and scraping device used for an annular mould. The charging and scraping device used for the annular mould comprises a charging funnel, a supporting plate, a scraping plate and a connection plate, wherein the charging funnel is arranged above a forming mould; an annular forming cavity used for grinding wheel forming is arranged in the forming mould; the supporting plate consists of an upper supporting plate and a lower supporting plate; the lower supporting plate is erected above the forming mould and is provided with shores; the upper supporting plate is provided with through holes in sliding fit with the shores; the upper end of the connection plate is fixedly arranged on the upper supporting plate; the lower end of the connection plate passes through a slot formed in the lower supporting plate to be connected with the scraping plate; the scraping plate comprises a fixed connection part and an expansion part, wherein the fixed connection part is fixedly arranged on the connection plate, and the expansion part is movably connected to the fixed connection part to conveniently regulate the width of the scraping plate. The width of the scraping plate of the charging and scraping device used for the annular mould is adjustable, and the charging and scraping device used for the annular mould can carry out charging and scraping operations on the annular mould of any specification.

Description

Technical field [0001] The present invention involves a scraper device. Specifically, it is a scraping device for ring molds. Background technique [0002] In the field of circular mold molding, the currently used and scraping technology, the original handicraft operation is a large part of it; the current scraping device used in the market is generally poured in, first throwing, and then scraping.Pour in at one time, the material is too concentrated, it is not easy to distribute evenly. The passing of the stirring stick and the place where the mixing rod is stirred is easy to cause the difference in accumulation density.This type of device can only ensure that the surface is scraped, and the lower layer of the lower layer may not guarantee its uniformity because the bridge phenomenon cannot be guaranteed. It may be severe in the bridge.The intensity and hardness of the product are uneven, resulting in unstable product quality.With the high cost of mechanical operations and cumbe...

AI Technical Summary

Problems solved by technology

Pour in one time, the material is too concentrated, it is not easy to distribute evenly, and the difference in bulk density is likely to be caused by the place where the stirring rod passes and the place where it does not pass when stirring the material

This type of device can only ensure that the material on the surface is scraped flat, but the material on the lower layer cannot guarantee its uniformity due to the bridge phenomenon. It may be that the material in the serious part of the bridge is empty, and the material in other places is solid. Such unevenness will directly lead to The strength and hardness of the product are uneven, resulting in unstable product quality

However, the cost of mechanical operation is high, the types are cumbersome, and there is no set of products suitable for various types of molds
