Abstract

The invention discloses an injection mold with multi-aperture adjustment. The injection mold comprises a first mold body and a second mold body, wherein the second mold body is installed at the lowerend of the first mold body, when a bottom mold body and a movable mold body need to be assembled for injection molding, a connecting column can be pressed downwards, a spring column installed at the lower end of the connecting column can move downwards at the same time, an adjusting plate descends along the side wall of a rotating groove while the spring column moves downwards, when the connectingcolumn moves to the bottom end, the adjusting plate is moved out of the rotating groove, the rotating column installed on the back face of the adjusting plate can enable the adjusting plate to rotatetowards one side under the elastic twisting of a torsional spring, the spring column reversely drives the adjusting plate to move upwards under pushing by elastic force of a third spring, the adjusting plate moves along the arc-shaped surface of the rotating groove while the adjusting plate upwards moves, a rotating plate rotates under movement of the adjusting plate, so that injection molding holes with different R-angle diameters are rotationally adjusted to the upper ends of a material injection hole, and the injection molding holes with different R-angle diameters can adapt to injection molding of different material pipes.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to an injection mold with multi-diameter adjustment. Background technique [0002] Injection molding is a processing method used in the mass production of certain complex-shaped parts, and is mainly used in the industrial field. The process of injection molding is to inject the heated and melted material into the mold cavity by high pressure, and after cooling and solidifying, a molded product is obtained. The mold is mainly composed of pouring system, molding parts and structural parts. Among them, the gating system is also called the runner system, which is a group of feeding channels that guide the plastic melt from the nozzle of the injection machine to the cavity. It is usually composed of a main channel, a runner, and a gate. A passage from the machine nozzle to the runner or the cavity. The entrance of the main channel is connected to the nozzle of the injection mol...
