Abstract

The invention relates to the technical field of molds, and discloses an injection mold for production and machining of automobile parts. The injection mold comprises a right mold and a left mold, wherein the inner side of the right mold is uniformly and alternately provided with fixing columns and fixing grooves, the inner side of the left mold is uniformly and alternately provided with another fixing grooves and another fixing columns, and the fixing columns are matched with the fixing grooves. According to the injection mold for production and machining of the automobile parts, through the arrangement of first springs, when the mold carries out injection molding, the pressure in the mold extrudes a venting plug, the venting plug moves to the outer side of a venting hole under the action of the pressure, the venting hole is in an automatic opening state, redundant gas in the mold can be discharged, when no redundant gas exists in the mold, the resilience force of the first springs can pull the venting plug inwards, so that the venting plug can be connected with the venting hole in a clamped mode, the venting plug blocks the venting hole, the inner wall of the mold can be kept complete, and molding of an injection molding part is facilitated.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to an injection mold for the production and processing of auto parts. Background technique [0002] Molds are various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping and other methods to obtain the required products. Molds are precision tools with complex shapes and withstand the expansion force of the blank. There are high requirements for structural strength, stiffness, surface hardness, surface roughness and processing precision. The development level of mold production is one of the important symbols of mechanical manufacturing level. Injection mold is a tool for producing plastic products; Injection molding is a processing method used in the mass production of certain parts with complex shapes. Specifically, it refers to injecting heated and melted plastic into the mold cavity under h...
