Limiting structure for limiting displacement of mould floating template

Abstract

The invention discloses a limiting structure for limiting displacement of a mould floating template. The limiting structure comprises a floating template and an L-type limiting block. The L-type limiting block comprises mutually perpendicular horizontal part A and vertical part A. The vertical part A is fixedly connected with a fixing plate or a mould base of a mould. The horizontal part A is matched with the floating template in a blocking mode. The limiting structure further comprises a Z-type limiting block. The Z-type limiting block comprises a vertical part B, and a horizontal part B anda horizontal part C which are positioned at two ends of the vertical part B and perpendicular to the vertical part B. The horizontal part B is fixedly connected with the floating template. The horizontal part A is matched with the horizontal part C in the blocking mode. The limiting structure is capable of improving the limiting precision, and improving a safety coefficient. The limiting structureis simple in structure, and convenient for processing and manufacturing. The processing cost is low, and the processing labor hours are less.

Description

technical field [0001] The invention relates to a mold structure, in particular to a position-limiting structure for limiting the displacement of a floating mold plate. Background technique [0002] Existing molds such as stamping dies, in order to facilitate the positioning and compression of the workpiece during the mold closing process, and in the mold opening process, in order to facilitate the separation of the workpiece and the mold, at least one of the two plates that are connected to the workpiece when the upper and lower molds are closed The plate is usually designed as a floating formwork, and the floating formwork slides up and down relative to the fixed plate of the upper and lower molds. Usually, the upper floating formwork on the upper mold is called the stripper plate, and the lower floating formwork on the lower mold is called the lower formwork. , in order to limit the displacement of the upper or lower floating formwork, a limit mechanism is often set to li...

Problems solved by technology

When the distance between the floating formwork and the fixed plate is relatively large during the movement of the mold, if bolts are used to fix the floating formwork, the length of the bolt’s screw will increase accordingly. Because the rigidity of the bolt is inversely proportional to the length of the bolt’s screw, the bolt’s The rigidity will be reduced. If the rigidity of the bolt is to be ensured, the diameter of the thread needs to be increased, and other parts connected with the bolt also need to be reprocessed, which is costly and takes a long time.

In this case, an existing improvement method is to use an L-shaped restricting block. The L-shaped restricting block includes two parts perpendicular to each other. The vertical part of the L-shaped restricting block is fixed to the fixed plate with bolts. The horizontal part of the block is overlapped with the floating formwork to limit the displacement of the upper or lower floating formwork. However, in this structure, if the distance between the floating formwork and the fixed plate is too large, the length of the vertical part of the L-shaped restriction block will be relatively long, so that the L-shaped The parameters such as rigidity and deflection of the limit block are reduced, the relative safety factor will be reduced, and the error will become larger
