Mold press plate

Abstract

A mold press plate comprises a press plate main body, a lower cushion block and an upper cushion block arranged on the lower cushion block, wherein the middle of the upper surface of the press plate main body is provided with a longitudinal groove, a longitudinal through hole is formed at the bottom of the groove, the upper cushion block and the lower cushion block are matched in a cambered surface mode, the upper cushion block and the lower cushion block are both located in the longitudinal groove and are placed on the bottom face of the longitudinal groove, meanwhile the middle of the upper cushion block and the middle of the lower cushion block are provided with an upper through hole and a lower through hole which correspond to the position of the through hole and allow a screw to penetrate. The mold press plate is characterized in that a base plate is arranged on the lower portion of one end of the press plate main body, and the upper end of the base plate is limited in the longitudinal through hole and can move forwards and backwards along the longitudinal through hole. The base plate can be regulated forwards and backwards, and can also be regulated upwards and downwards, so the regulation range is widened, height requirements for different workpiece molds can be met, clamping strength is high, and the utilization and regulation are both convenient; and the overall structure is simple, reasonable and practical.

Description

Technical field [0001] The invention relates to a fixture for machine tool accessories, in particular to a mold pressing plate for fixing a workpiece or mold to be processed on the table of the machine tool. Background technique [0002] The mold pressing plate is the simplest and most commonly used fixture in the mechanical processing industry. The traditional flat mold clamp is used in conjunction with the spacer. Depending on the thickness of the workpiece, the spacer must be replaced accordingly, but the spacer is often prone to fall and lose. Because of this, it has been gradually replaced by mold pressing plates of various structures on the existing market. [0003] For example, the Chinese utility model patent No. 99206225.X includes a pressure plate with a longitudinal slot and a pair of upper and lower gaskets for pressing screws. The characteristic is that the pressure plate is arched on the back A row of finely distributed racks is arranged along both sides of the long ...

AI Technical Summary

Problems solved by technology

Its shortcoming is that the pressing surfaces at both ends of the pressing plate are fixed, which brings certain troubles to the clamping of some angled and tapered products, and the fastness of the clamping will also decrease accordingly.

However, this kind of folding gasket can only be adjusted up and down, and cannot be adjusted back and forth, so that the adjustment range is small, which cannot well meet the needs of mold clamping, and the adjustment is more troublesome.
