Abstract

The invention discloses an injection mold with a water blowing mechanism. The injection mold comprises an injection molding mechanism and an upper cover mechanism, wherein one side of the injection molding mechanism is movably connected with the upper cover mechanism, the pressure in the mold is increased, and residual water spots in the mold are pressed into a suction filtration pump through a suction pipe to be recycled. According to the injection mold, one end of an air conveying groove is connected with a lower forming cavity, the other end of the air conveying groove communicates with anair conveying pipe, one end of a water flowing groove is connected with a water discharging groove, so that after the mold is used, air flow passes through an air inlet hose through an air pump, residual water spots in the lower forming cavity are blown through a blowing gun, the residual water spots is discharged into a water containing groove through a water flowing groove, finally, water spotsare pumped in through the suction filtration pump and discharged into a cooling water inlet pipe through a water discharging pipe, so that water flow can be conveniently input into the mold through the cooling water inlet pipe in the next injection molding process, the situation that water is remained in the molding cavities for a long time to cause internal corrosion is avoided, the service lifeof the molding cavities is prolonged, the resource utilization rate is increased, and environmental protection and energy saving are realized.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to an injection mold with a water blowing mechanism. Background technique [0002] The mold generally includes two parts, the movable mold and the fixed mold (or punch and die), which can be separated or combined. Take out the parts when they are separated, and inject the blank into the mold cavity to form when they are closed. The mold is a precision tool with a complex shape and bears the bulging force of the billet. It has high requirements for structural strength, stiffness, surface hardness, surface roughness and machining accuracy. The development level of mold production is one of the important symbols of the level of mechanical manufacturing. Injection mold is a tool for producing plastic products; it is also a tool for giving plastic products complete structure and precise dimensions. Injection molding is a processing method used in the mass production of certain ...
