Equipment for eliminating unsaturated film phenomenon for plastic injection molding

Abstract

The invention relates to the technical field of plastic injection molding, and discloses equipment for eliminating an unsaturated film phenomenon for plastic injection molding. The equipment comprisesa movable frame; a support rod is movably connected to the interior of the movable frame; a spring frame is movably connected to the surface of the support rod; hot melting blocks are movably connected to the left and right sides of the spring frame, and connecting rods are movably connected to the surfaces of the hot melting blocks; inclined plates are movably connected to the bottoms of the hotmelting blocks; flow extending pipes are movably connected into the inclined plates; a flow dividing pipe is movably connected to the top of the spring frame; flow guiding pipes are movably connectedto the left side and the right side of the flow dividing pipes; compression springs are movably connected to the surfaces of the flow dividing pipes; and feeding pipes are movably connected to the upper ends of the compression springs. The rear spring frame extends and pulls the hot melting blocks to slide on the surface of a sliding rail, the hot melting blocks move to apply a certain force to the surface of the movable frame through the connecting rods, the rear movable frame gets close to the center, namely, a certain force is applied to the surface of the raw material, and therefore the effects of applying pressure, reducing the flowing space and reducing the raw material adhesion amount are achieved.

Description

technical field [0001] The invention relates to the technical field of plastic injection molding, in particular to a device for eliminating unsaturated film phenomenon for plastic injection molding. Background technique [0002] Injection molding is a method of producing industrial products; products usually use rubber injection molding and plastic injection molding; injection molding can also be divided into injection molding molding method and die-casting method, among which plastic injection molding is more common, and the existing plastic injection molding equipment and technology are relatively mature. , so the yield of injection molded products is also higher. [0003] However, after understanding the injection molding process, it is found that due to the distance between the injection mold and the injection pipe, although the traditional injection molding pressure mechanism can squeeze the plastic into the mold, the plastic in the flowing state is relatively viscous, ...

[0003] However, after understanding the injection molding process, it is found that due to the distance between the injection mold and the injection pipe, although the traditional injection molding pressure mechanism can squeeze the plastic into the mold, the plastic in the flowing state is relatively viscous, and the flow process The resistance received in the process is relatively large, and some plastics will stick to the surface of the flow pipe, which will reduce the raw materials entering the mold and affect the unsaturated film phenomenon. Therefore, a plastic injection molding equipment for eliminating unsaturated film phenomenon should be developed. pregnancy
