DIRECT COMPRESSION AND GATE CUTTING STRUCTURE OF AN INJECTION MOLDS AND OPERATING METHOD THEREOF

摘要

The present invention relates to a direct compression and gate cutting structure of an injection mold and a method of using the same. To this end, in the injection mold composed of the upper mold 10 and the lower mold 15, the core pin 40 having the same cross-section as the shape of the gate 32, and can be reciprocated in the lower mold 15; Transfer means for reciprocating the core pin 40; And a runner 35 formed in the lower mold 15 and communicating with the reciprocating transfer path of the core pin 40, wherein the core pin 40 passes through the gate 32 to enter the cavity 30. As a result, compression is applied to the cavity 30, and the injection molding in the cavity 30 is provided with a direct compression and gate cutting structure of the injection mold, which is cut from the runner 35.;Injection, Molding, Core, Runner, Gate, Cavity, Forward, Cutting, Compression, Melting, Resin
