Innovative design of side mould structure based on TRIZ theory

Abstract

In order to meet the requirements of domestic prefabricated buildings and PC production lines, taking the side mould structure as the research object, an innovative design of the side mould structure based on TRIZ theory is proposed. The tools of TRIZ’s nine-screen method and conflict matrix are used to complete the innovation of the plugging device for the side mould reinforcement hole,and by using steel wire connection, the aluminum alloy sealing device can complete synchronous action and solve the problem of reinforcement hole leakage. Through the object field analysis tool in the TRIZ theory, to establish the function related to the existing system or new technology system problems, the double rocker mechanism is used to make the reset action and the demolding action of the side mould sealing device complete in a linked manner, to realize the design of the demoulding device and the side mould fixing device. The calculation and verification of the side mould structure verify that the side mould stiffness meets the production requirements, and improves the accuracy and placement accuracy of the side mould.
