Tungsten steel dry pressing die size and thickness requirements

May 27, 2019

The size of the tungsten steel dry pressing die should be larger than the working area when it is used. The standard template size is selected to a certain extent. The positional configuration of the template locking screw is related to the type of the die and the size of the template. Among them, single-engine molds are most often used with locking screws on the four corners, and the most standard form of work area can be widely used. Long molds and continuous molds are most often placed in the four corners and in the middle with locking screws.

Thickness of tungsten steel dry pressing die

The thickness selection of the template has an absolute relationship with the structure of the tungsten steel dry pressing die, the type of press processing, the press working force, and the press working precision. It is difficult to determine the thickness of the mold according to theoretical calculations. Generally, it is obtained by experience. The thickness of the template used for design should be as small as possible, and the mold height and clamping height should be standardized to facilitate procurement and inventory management.

The shrinkage and deformation of the tungsten steel dry pressing die, some plastic parts are easy to deform, no matter how to prevent, the plastic parts will be deformed during the cooling stage. Under this condition, the shape of the forming mold is changed to accommodate the geometrical deviation of the plastic part. For example, although the wall of the plastic part is kept straight, the center of the reference has deviated by 10 mm; the base of the mold can be raised to adjust the amount of shrinkage of this deformation.www.yxhgmould.com
