Description

Technical Field

[0002] When producing PU foam board, it is necessary to first mix polyurethane raw materials, catalysts, foaming agents, etc. according to a certain proportion. After the raw materials are mixed, they are injected into the mold through an injection machine, heated and foamed, so that the raw materials expand into foam, and the foam is solidified and formed in the mold to form a foam board. The Chinese patent announcement number CN220163062U discloses a foam molding machine. The patented technology is provided with a down-pressing component and a top-material component. When the upper mold moves down and closes the mold with the lower mold, the down-pressing component squeezes the contact plate on the top-material component, so that the push plate moves down in the mold cavity of the lower mold. After molding, the down-pressing component is driven to move up during the upward movement of the upper mold. Under the elastic force of the spring, the push plate is moved up and reset, and the foam product formed in the mold cavity is pushed out at the same time, thereby facilitating the demoulding of the foam product and improving efficiency.
