摘要

The present invention relates to a door guard manufacturing method coupled to the tempered glass door rim, a door guard manufactured using the same and a mold apparatus for manufacturing the door guard by this, in more detail in the rim of the door, such as apartment entrance door, tempered glass door Regarding the manufacturing method of the door guard coupled to the edge of the tempered glass door to make the windshield member and the safety member constituting the door guard to be combined into a single product, a door guard manufactured using the same and a mold apparatus for manufacturing the door guard will be. The present invention for realizing this in the extrusion molding apparatus 200 for heating and melting and extruding a synthetic resin, the door guard mold 300 provided at the end of the extrusion molding apparatus 200; At the tip of the door protector mold 300, an extruded resin is formed as a first hollow 311. A first mold part 310 provided with a first core 312 to be injected but having a first guide core 312a on one side and a first windproof member core 312b on the other side; The second mold 322 is detachably coupled to the first mold part 310, and a second core 322 is provided to inject the extruded resin into the second hollow 321, and a second guide core 322a is disposed at one side thereof. A second mold part 320 having a wind-entry hole 322b to which the wind-proof member 120 enters; A third core 332 is provided to be detachably coupled to the second mold part 320 and the extruded resin is injected into the hollow 331, but a third guide core 332a is formed at one side of the third core 332. ) Is disposed, and the other side is characterized by consisting of a third mold portion 330 having an inclined pressure core 332b and a heating member (H) of the inclined shape is lowered into the inside.
