Technical Field

The utility model relates to the technical field of molds, in particular to a processing mold which is easy to demould.

Background Art

The stamping die is an auxiliary device in the stamping process of parts. In the existing stamping die, during the stamping process, the workpiece is prone to produce debris under the action of pressure. After demolding, the generated debris is easy to remain in the lower die, so that during the subsequent stamping process, the workpiece is affected by the debris, which reduces the surface smoothness of the product and affects the product quality.

The prior art CN217941665U discloses an automobile parts processing mold that is easy to demould, which effectively solves the problem that the workpiece is prone to generate debris under pressure during the current stamping process, affecting the subsequent stamping process. The utility model comprises a workbench, a cylinder is installed on the top of the workbench, an upper mold is installed on the output end of the cylinder, a lower mold is installed below the upper mold, a rotating component is installed at the bottom end of the lower mold, and a supporting component is installed at the bottom end of the lower mold. The rotating component includes a supporting frame symmetrically arranged on both sides of the lower mold, and the supporting frame is fixedly connected to the inner top wall of the workbench. The utility model drives the lower mold to rotate half a circle through the output shaft of the first motor, so that the opening of the lower mold faces downward, so that the workpiece falls under the action of its own gravity, which is convenient for demoulding, and the debris generated in the stamping process in the lower mold falls, thereby ensuring that the inner wall of the lower mold is smooth when working, thereby improving the subsequent stamping effect.

However, when the above-mentioned automobile parts processing mold that is easy to demold is in use, after unloading is completed, the output shaft of the first motor rotates in the opposite direction, driving the lower mold to rotate half a circle. At this time, the output shaft of the second motor rotates, driving the sliders to approach each other, so that the support rods are reinserted into the support grooves, thereby supporting the lower mold during stamping and ensuring the normal progress of the stamping process. However, when the waste material drops from the lower mold, the waste material is easy to fall into the slide groove of the slider, causing the slider to get stuck, making it difficult to position the slider, seriously reducing the stability of the lower mold during support, and making it inconvenient to use.
