Description

TECHNICAL FIELD

[0001] The utility model relates to a toilet bowl forming equipment, specifically a pneumatic draw mould device for horizontal forming machine. BACKGROUND

[0002] At present, the high-pressure forming machine for producing toilet bowl sanitary wares of domestic and foreign sanitary ceramic production enterprises all adopts the up-down and left-right open mould type to produce the blank body. The high-pressure forming equipment of this traditional type is mostly suitable for the forming process of a large number of blank bodies of the same model. In the forming process, the horizontal pulling of the mould is realized through the pulling assembly such as a belt to achieve the purpose of opening and closing the mould. In the traditional forming machine, a tension pulley needs to be installed in the middle part of the belt to realize the tension control of the belt to prevent the belt from loosening and slipping in the repeated back-and-forth movement. However, the tension pulley needs to be adjusted every time a certain period of time is used or a blank mould of a different type (with different weights) is replaced, and the process is complicated. If forgotten, the danger of the compactness of the blank mould being not tight due to the insufficient tension of the belt will occur, resulting in poor blank forming effect, high scrap rate, and serious influence on work efficiency and quality.
