[0002] Plastic shells are widely used in household appliances, such as electric steamers, electric stew pots, household smart trash cans, household water dispensers, etc. Its structure is generally a barrel-shaped structure with a large depth. In the molding of such a deep product, the demoulding stroke is large. The mold has a specific contour or inner cavity shape. The application of a contour shape with a cutting edge can make the blank separate (punch) according to the contour shape. The application of the inner cavity shape can make the blank obtain a corresponding three-dimensional shape. The mold generally includes a movable mold and a fixed mold (or a convex mold and a concave mold), which can be separated or combined. When separated, the workpiece is taken out, and when closed, the blank is injected into the mold cavity for forming. The mold is a precision tool with a complex shape. It bears the expansion force of the blank. It has high requirements for structural strength, rigidity, surface hardness, surface roughness and processing accuracy.
