The working principle of the mold opener-closer

The working principle of the mold opener-closer:

The opener-closer is a mold component that adjusts the friction between the template and the nylon sleeve by tightening the conical bolt, primarily used to increase the opening resistance between the fixed and movable molds, ensuring that the runner plate and panel open before the fixed template and movable template.

The opener-closer can increase the opening resistance of a certain mold surface, allowing other mold surfaces to open first. It usually needs to be matched with a fixed distance mold separating mechanism to achieve orderly mold separation. This structure can adjust the opening resistance by adjusting the compression amount of the spring, with good effect.

In summary, the opener-closer operates as a mechanical device controlling the opening and closing sequence of the mold plates. It can be applied in three-plate molds, playing a significant role in preventing mold deformation and enhancing the overall quality of mold products.
