Abstract

The invention discloses a shutter for a die. The shutter comprises a depression bar, a pressure arm support, a pressure arm, a fixture block, and a spring footstock, wherein the depression bar is suitable for being fixed on a spring plate; a depression bar groove is formed in one side, departing from the spring plate, of the depression bar; a first bump and a second bump are arranged on one side, departing from the spring plate, of the depression bar; a first bump groove is formed in the first bump; the pressure arm support is suitable for being fixed on a movable die; the pressure arm is arranged on the pressure arm support in a pivot manner; a pressure rod with an idler wheel is arranged on the pressure arm; the idler wheel is suitable for rolling inside the depression bar groove and the first bump groove; the fixture block is arranged at the top of the pressure arm; a first buckle section is arranged on the fixture block; a second buckle section matched with the first buckle section is arranged on a fixed die; the spring footstock is suitable for being fixed on one of the movable die and the fixed die; a spring is arranged between the spring footstock and the surface of one side, departing from the spring plate, the pressure arm. The shutter disclosed by the invention is suitable for die fabrication; strong impact caused by a collision contact can be reduced; the service life of the die is prolonged; meanwhile, the shutter is more stable to carry out die sinking movement; the die quality is improved.

Description

technical field [0001] The invention relates to a shutter for a mold. Background technique [0002] The current level of mold manufacturing is constantly improving, and various new technologies are used in the field of mold design and manufacturing. And many new accessories such as three-plate molds, progressive molds and other complex or multi-sequence molding molds have been born. [0003] The shutter of the mold is widely used in the current mold as an accessory for the sequential opening of the mold, so various shutters emerge as the times require. The traditional shutter adopts the principle of damping friction to lock the mold when it is parted once. However, the friction of damping parts tends to be unstable during long-term use, which will affect the use effect and working life of the mold. Contents of the invention [0004] The present invention aims to solve one of the above-mentioned technical problems in the prior art at least to a certain extent. For this ...
