Abstract

The invention discloses a magnetic-ring driving wheel injection mold. The injection mold comprises a fixed mold base plate, a fixed mold plate, a movable mold block, a movable mold bottom plate and a mold foot plate, and the fixed mold base plate, the fixed mold plate, the movable mold block, the movable mold bottom plate and the mold foot plate are sequentially arranged from top to bottom; mold cores are arranged below the fixed mold base plate, and the bottoms of the mold cores are fixedly connected with the mold foot plate; mold sleeves are arranged on the tops of the mold cores, and molding pins are arranged in the mold sleeves; ejector sleeves are arranged on the outer sides of the mold cores and are in sliding connection with the mold cores, and a guide column is arranged on one side of the fixed mold base plate; a sprue sleeve is arranged in the middle of the fixed mold base plate, and a runner is arranged at the lower end of the sprue sleeve; the runner is arranged in an inclination manner and is communicated with the mold cores; and ejector rods are arranged at the front ends of the mold cores, and haff parts are arranged above the ejector rods. A product machined by the magnetic-ring driving wheel injection mold brings convenience to lathing of the cavity and linear cutting of a synchronous gear molding cavity, and the product can be conveniently ejected out.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to an injection mold for a magnetic ring drive wheel. Background technique [0002] The thermal balance of the injection mold controls the heat conduction of the injection molding machine and the mold is the key to the production of injection molded parts. Inside the mold, the heat brought by the plastic (such as thermoplastic) is transferred to the material and the steel of the mold through thermal radiation, and to the heat transfer fluid through convection. In addition, heat is transferred to the atmosphere and formwork by thermal radiation. The heat absorbed by the heat transfer fluid is taken away by the mold temperature controller. The heat balance of the mold can be described as: P=Pm-Ps. In the formula, P is the heat taken away by the mold temperature controller; Pm is the heat introduced by the plastic; Ps is the heat emitted by the mold to the atmosphere. The purpose...
