Description

Technical Field: The present invention relates to the technical field of building plastic formwork preparation molds, and particularly to a building plastic formwork wall preparation mold. Background Art: With the development of the construction industry, plastic formwork is now widely used in the construction process to replace traditional wooden formwork and steel formwork. In order to adapt to the strength of the plastic formwork during concrete pouring, several internal threads are required to be provided around the plastic formwork for reinforcement connection. The production of building plastic formwork requires an injection molding process, including filling, pressure holding, cooling, and demolding. Demolding is the last link in the injection molding of plastic formwork and has a very important impact on the quality of the product.
