Embodiment Construction
[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0022] see Figure 1-2 , an injection molding device for removing residual raw materials after injection molding of a flywheel mold, comprising a connecting pipe 1, the bottom of the connecting pipe 1 is fixedly connected with a mounting block 2, and a through hole is opened inside the mounting block 2 to allow the raw materials in the connecting pipe 1 to flow into the circulation In the hole 7, the nozzle body 3 is installed on the bottom of the installation...

The invention relates to the technical field of flywheel machining, and discloses an injection molding device for removing residual raw materials after flywheel mold injection molding. The injection molding device comprises a connecting pipe, wherein the bottom of the connecting pipe is fixedly connected to a mounting block, a spray head body is fixedly connected to the mounting block, a nozzle is fixedly connected to the bottom of the spray head body, and a fixing sleeve is installed inside the spray head body. When upward thrust of a hydraulic pressure in a circulation hole borne by a pressure plate is larger than downward pressure of an elastic spring, the pressure plate moves upwards to drive an extrusion rod to move upwards so that raw materials can be ejected out of a nozzle hole, when the upward thrust of the hydraulic pressure in the circulation hole borne by the pressure plate is smaller than the downward pressure of the elastic spring, the pressure plate moves downwards to drive the extrusion rod to be inserted into the nozzle hole, injection molding is stopped, and meanwhile, the residual raw materials in the nozzle hole are extruded out, so that the effect of cleaning the residual raw materials on the nozzle while injection molding is controlled is achieved.
Description
technical field [0001] The invention relates to the technical field of flywheel processing, in particular to an injection molding device for removing residual raw materials after injection molding of flywheel molds. Background technique [0002] A flywheel is a disc-shaped part with a high moment of inertia that acts like an energy store. In the processing of the flywheel, it is often necessary to inject the mold in advance. The commonly used injection molding machine, but the current injection molding machine uses the thrust of the screw to inject the plasticized molten plastic into the closed mold in a high-pressure and fast manner. In the cavity, the equipment for obtaining the product after cooling and solidifying. [0003] And when the commonly used injection molding equipment completes the injection, the nozzle will contain residual molten raw materials. When the viscosity of the raw materials is lower, this residual phenomenon is more serious, and the solid substance...
