Method for producing squatting pan by high-pressure molds

Abstract

The invention discloses a method for producing a squatting pan by high-pressure molds. A horizontal high-pressure grouting forming device is used for producing the squatting pan. The high-pressure grouting forming cycle includes the following steps of (1) grout filling, (2) grouting, (3) grout returning and (4) strengthening, wherein in the step of (1) grouting filling, grout is conveyed to the molds through a pneumatic diaphragm pump, in the step of (2) grouting, external pressure acts on the grout in the molds so that the grout can be dehydrated and hardened to be shaped, in the steps of (3) grouting returning, extra grout in a hollow grouting area of a blank is discharged, and in the step of (4) strengthening, compressed air is led to an inner cavity of the blank, so that water in the blank is uniform, and the strength of the blank is improved. The micro-reticular resin mold is adopted, the device is in a horizontal pouring mode, and a reliable guarantee is provided for demolding of the blank, and accordingly the blank is not prone to deforming; the device is of a double-mold structure, multiple high-pressure resin molds can be arranged, and the device can be used for producing wash basins and also can be used for producing squatting pans by replacement of the molds; according to the method, energy conservation and emission reduction can be achieved, clean production can be achieved, the qualified rate of products and production efficiency are greatly improved, and meanwhile, work intensity of workers is greatly reduced.

Description

technical field [0001] The invention relates to an improvement of a squatting pan production method, in particular to a squatting pan production method that is different from the traditional use of plaster mold grouting, which can achieve energy saving, emission reduction, clean production, high product yield, and greatly increased production efficiency. The method of using high-pressure molds to produce squatting toilets has improved greatly, the working environment of workers has been greatly improved, and the work intensity has been greatly reduced. Background technique [0002] The conventional production method of squatting pan is grouting molding, also known as pouring molding. Its principle is based on the physical characteristics of porous gypsum molds that can absorb water, and ceramic powder is made into fluid mud, and then injected into porous molds (mainly for Gypsum mould), water is absorbed by the mold (gypsum) to form a uniform mud layer with a certain thickne...

AI Technical Summary

Problems solved by technology

Disadvantages: (1) high labor intensity, many operating procedures, and low production efficiency; (2) long production cycle, large area occupied by plaster molds; (3) injection parts have high water content, low density, large shrinkage, and are easy to burn when fired. out of shape

(4) Large mold loss

(5) Not suitable for continuous, automated and mechanized production

[0005]There are many problems in the existing production method of grouting molding squat toilet: (1) According to the difference of product and structure, the number of times of using a plaster mold is 60- About 80 times, after reaching the number of times, the plaster molds can only be scrapped, which not only occupies a certain proportion of the production cost of the product, but also how to deal with a large number of waste plaster molds in an environmentally friendly way is also a problem; (2) plaster molds need to be baked In order to ensure its water absorption, and the drying mold needs to consume a certain amount of energy, such as natural gas; (3) The operating temperature of the grouting molding is generally controlled at 25-37 degrees, and the molding workshop cannot open windows most of the time, so the dust is large and the temperature is high. High, poor environment, which is extremely unfavorable to workers' health; (4) Low production efficiency, with an average daily output of about 30 pieces per day for two workers; (5) Lip-body joints were required for early squatting pan molding, and later with the advancement of molding technology, Squatting toilet molding does not require lip-body jointing anymore, but manual lip cutting process is still required. Since product demoulding, lip cutting and other processes need to be completed manually, the product yield rate is not high and is relatively unstable
