INSTRUCTIONS: The present invention claims the benefit of Korean Patent Application No. 10_2〇〇9〇128〇〇9, which applied to the Korea Intellectual Property Office on December 21, 2009, and the content disclosed here is The whole is incorporated as a reference. TECHNICAL FIELD OF THE INVENTION The present invention relates to a metal mold. [Prior Art] A metal mold represents a device in which a hole having a specific shape is filled, wherein the hole is filled with a liquid resin and cured to form a molded product. A nozzle unit can be installed in the metal mold to inject the resin into the hole. The nozzle unit can have a heating unit that heats the resin to save the amount of resin and improve the quality of the molded product. This causes a local temperature rise in the hole adjacent to the nozzle. The rise in the local temperature of the metal mold has caused a temperature difference in the metal mold, thus causing thermal stress in the metal mold. SUMMARY OF THE INVENTION The present invention provides a metal mold having a structure that avoids heat conduction. One aspect of the invention provides a metal mold. A metal mold according to an embodiment of the present invention may include a nozzle unit 'release resin thereof, a nozzle plate supporting the nozzle unit, a template having a die hole 3 201121763 in the template and the resin being Filling the die hole and a dummy hole 'between the nozzle unit and the die hole, so that the resin is filled into the dummy hole and the die hole is insulated. The metal mold may further include a connecting plate interposed between the nozzle plate and the template. Here, the connecting plate has a connecting passage formed therein, and the connecting passage connects the nozzle unit to the die hole. The dummy hole may be formed in the connecting plate such that the dummy hole is interposed between the nozzle and the connecting passage. The nozzle unit may include a nozzle having a supply passage formed therein and the resin is supplied through the supply passage, a heating unit that heats the resin supplied through the supply passage, and a sleeve having the nozzle embedded therein . The metal mold can further include a first air gap between the nozzle and the sleeve. The metal mold may further include a bracket interposed between the nozzle unit and the nozzle plate to support the nozzle unit. The metal mold can further include a second air gap between the bracket and the sleeve. The metal mold may further include a third air gap interposed between the bracket and the nozzle plate. Additional aspects and advantages of the invention will be set forth in part in the description which follows. [Embodiment] The features and advantages of the present invention will become apparent from the following description and description. A metal mold in accordance with a particular embodiment of the present invention will be described in greater detail below with reference to the accompanying drawings. The same or corresponding components will be denoted by the same component symbols regardless of the figures, and the repeated description will be omitted. Fig. 1 is a perspective view of a metal mold 1 according to an embodiment of the present invention. And Figure 2 is a cross-sectional view showing a portion of the metal mold 1000 in accordance with an embodiment of the present invention. As shown in FIG. 1 and FIG. 2 , the metal mold 1000 of the present invention includes a nozzle unit 1 , a nozzle plate 210 , a connecting plate 220 , a template 230 , a bracket 150 , a counter hole 224 , A first air gap 3 10, a second air gap 320 and a third air gap 330. Therefore, the metal mold 1000 according to an embodiment of the present invention can prevent heat from being conducted from the nozzle 130 to the adjacent plate. The metal mold 1000 may have a form in which the nozzle plate 210, the connecting plate 220, the template 230, and the plurality of auxiliary plates 202, 204, 206, 208, 212, and 214 are sequentially stacked one upon another. A groove supporting the nozzle unit may be formed within the nozzle plate 21A. The nozzle unit 100 can include a nozzle 130, a heating unit 丨2〇, and a sleeve 140. A supply passage 110 for supplying resin through the supply passage may be formed in the nozzle 130. A heating unit 120 for heating the resin supplied through the supply passage 110 may be formed around the supply passage 11(). [S] The heating unit 120 may include a heating wire that generates heat when supplied. 5 201121763 There is a supply channel iio with heating element 120 can be called a hot ramp. The nozzle 130 can be embedded in the sleeve 140. The sleeve 14A can have a structure that surrounds the nozzle 130 and can form the exterior of the nozzle unit. Here, a groove in which air is filled (i.e., the first air gap 31A) may be disposed between the nozzle 130 and the sleeve 14A. The first air gap 310 prevents heat transfer from the nozzle 13 turns to the nozzle plate 210, the connecting plate 22, and the template 23A adjacent to the nozzle 130. The sleeve 140 can be supported by the bracket 150. The bracket 15A may have a shape extending longitudinally to conform to the shape of the nozzle unit 100 and may have a hollow portion formed therein. The nozzle unit 11A can be embedded in the hollow portion. A top end portion of the sleeve 140 may be formed in the shape of a cone having a similar cross-sectional area to a bottom end, and a recess in which air is filled (i.e., the second air gap 320) may be formed on the bracket 15 ( And a slanted portion of the top end portion of the tapered sleeve 140. The second air gap 32 〇 can prevent heat conduction from the nozzle 130 to the nozzle plate adjacent to the nozzle 13 ], the connecting plate 220 and the template 230 » The bracket 150 can be swept by the nozzle plate 21G, and the nozzle plate 21 has a groove formed in Wherein the bracket 15G can be embedded in the recess. The nozzle plate can accommodate the bracket 150 and support both ends of the bracket 15〇. A recess in which air is filled (i.e., 'third air gap 33') may be formed between the bracket 150 and the nozzle plate 21A. The third air gap 33〇 prevents heat transfer from the nozzle 13〇 to the nozzle plate 21〇 adjacent to the nozzle 13〇, the connecting plate 220, and the template 230. 6 201121763 The connecting plate 220 can be coupled to an upper top end of the template 230. A connecting passage 222 that vertically traverses the connecting plate 220 according to the position of the supply passage 110 may be formed within the connecting plate 220. The connecting passage 222 can be interposed between a die hole 232 (to be described below) and the supply passage 110, and provides a path for the resin to be discharged through the supply passage 110 into the die hole 232. Here, a passage having no heating means and similar to the connecting passage 222 is referred to as a cold runner. The dummy hole 224 may be formed on an upper surface of the connecting plate 220 around the connecting passage 222. The dummy hole 224 can provide a space in which the resin can be filled between the supply passage 110 and the connecting passage 222. The resin released through the supply passage 110 is injected into the die hole 232 through the connecting passage 222 after the resin is filled into the dummy hole 224. If the resin initially released through the supply passage 110 is a cold slag and is directly filled into the die hole 232, then the cold slag can cause a shortage in the molded product because the flow of the cold check is not smooth enough. However, the metal mold 1000 of the present embodiment can avoid defects in the molded product because the initially released cold slag is filled into the dummy holes 224. Further, the resin filled in the dummy hole 224 can serve as an insulating material between the nozzle unit ι and the connecting plate 220, and heat conduction from the nozzle no is prevented to the connecting plate 220 and the template 230. The template 230 can be shank to a bottom end portion of the connecting plate 220. A die hole 232 having a particular shape can be formed in a portion of the template 230 that conforms to the location of the connection channel 222. The die hole 232 can be filled with resin and the tree [s] 7 201121763 grease can be hardened within the die bond 232 to form a molded product having a particular shape. Therefore, since the metal mold 1 of the present embodiment has the first air gap 310, the second air gap 32, the third air gap 33, and the dummy hole 224, heat conduction from the nozzle 130 to the adjacent nozzle 130 can be avoided. The nozzle plate 210' connects the plate 22 and the template 23 (this avoids thermal stress from being generated in the metal module 1000. Further, since the dummy hole 224 receives the cold slag initially discharged through the supply passage 110, it can be avoided The occurrence of defects caused by the initially released cold slag in the product. According to an embodiment of the invention, heat transfer from a nozzle to other portions of a metal mold adjacent to the nozzle can be avoided. Although reference has been made to a particular embodiment The spirit of the present invention is described in detail, but it is intended to be illustrative and not restrictive. The invention may be modified or modified without departing from the scope and spirit of the invention. Many other embodiments are available from the scope of the accompanying patent application.
