Description

Technical Field

[0001] The invention belongs to the technical field of hot-pressing veneer forming and relates to a hot-pressing veneer placing jig. Background Art

[0002] Real wood decorative parts are products made by processing wood veneer materials through processes such as compounding, hot pressing, injection molding, milling, and spraying. Among them, hot pressing is one of the important process links in the formation of real wood device parts, which determines the final forming quality of real wood decorative parts. During the hot pressing process, the veneer material to be processed needs to be placed in a hot pressing mold. The high temperature of the hot pressing mold softens the veneer and applies pressure to the veneer to fix the veneer into shape.

[0003] In the existing veneer hot pressing mold, the jig and the mold used for forming are usually integrated. After the veneer is hot pressed on the forming surface of the jig, the staff needs to manually remove the veneer from the jig, or use a crowbar or a push pin to remove the veneer from the jig. Due to the high temperature environment of hot pressing, the staff is easily burned by the high temperature during the process of removing the veneer, and the veneer is easily damaged during the process of prying the edge of the veneer.

[0004] Therefore, in view of the above-mentioned problems existing in the existing veneer hot pressing jig, the present invention discloses a hot pressing veneer placement jig. Summary of the invention

[0005] The purpose of the present invention is to provide a hot-pressed veneer placement jig, which is convenient for workers to safely and efficiently remove the veneer, avoid scalding the workers, and improve the efficiency of removing the veneer.
