<p>A die pressing plate comprises a pressing plate main body (1), a lower spacer block (2) and an upper spacer block (3). A longitudinal groove (1.1) is formed on the middle part of an upper surface of the pressing plate main body. A longitudinal through hole (1.2) is formed in the bottom of the groove. The upper spacer block and the lower spacer block are fitted through camber surfaces, positioned in the longitudinal groove and placed on a bottom surface of the longitudinal groove. Middle parts of the upper spacer block and the lower spacer block are respectively provided with an upper through hole (3.1) and a lower through hole (2.1). At least one of a front lateral part and a rear lateral part of the upper spacer block is provided with an extending part (3.2) that extends downward. An engaging section (3.3) is arranged at a lower end of the extending part. Correspondingly, guide grooves (1.3) are formed on side walls at two sides of the longitudinal through hole and are fitted with the extending part in a slidable manner. The engaging section on the extending part is limited on a bottom surface of the pressing plate main body through elastic deformation of the extending part. The die pressing plate is simple and rational in structure, is convenient and quick to assemble and use, and is low in cost.</p> |
