New description: [New technical field] This creation is a hot runner structure 'refers to a structure that can heat the hot runner evenly. [Prior Art] In the application of the new patent No. 325916, the heating structure of the hot runner includes a hot runner body, and the bottom end of the hot runner body extends downwardly from a column, and the column One end of the tube is closed, and the tube column forms a spiral heating groove on the outer wall surface, and a heating coil is arranged on the heating groove, so that the heating coil and the column are combined with each other for the hot runner body. For heating purposes. However, the heating method causes the m-degree of the central position of the hot runner body to be at both ends of the hot flooding body, so that the plastic on the hot-washing lane hot-washing body cannot be uniformly heated, thus easily causing The injection molded product cannot be molded to produce a poor quality product; therefore, the heating structure of the hot runner body is further improved to improve the conventional hot runner hot runner body which cannot uniformly heat the plastic. Disadvantages. [New content] Therefore, the main purpose of this creation is to provide a hot runner structure that allows the plastic to be uniformly heated during heating to prevent the plastic from being stably formed during injection molding and to reduce the quality of the product. The technical means for achieving the above purpose is to construct the hot runner junction 3 M356609, comprising: a heating pipe which respectively forms more than one portion adjacent to the center; and a hot runner body which is sleeved on the above heating In the tube, the hot runner body has a reaming hole at the top end, and a bottom end of the hot runner body extends downwardly from a heat pipe, the bottom end of the heat pipe is provided with a closing member; and a heating coil and a loop It is provided on the outer diameter surface of the heating pipe. When the heating coil is electrically heated to heat the heating pipe and indirectly heats the hot runner body, since the heating pipe has a hollow portion near the center, the heat receiving surface of the heat pipe at the center can be reduced, and the center of the heat pipe is promoted. The temperature at both ends of the heat pipe is &; thereby, to solve the problem that the temperature of the conventional hot wash lane is not caused to cause the product to be low. [Embodiment] Referring to the first figure, the present invention is a hot runner structure including a force ..., f (10), a hot runner body (2 〇), and a heating coil (3 〇). Referring further to the second figure, the heating tube (10) is in the form of a hollow cylinder. The heating tube (1Q) forms more than one town: part () and the heating officer (10) The heating groove (12)' is carried in a continuous manner along the outer diameter surface, and the number of rings of the feeding material (12) at both ends of the heating f (1Q) is larger and denser than the central position of the heating pipe (12). The hot body (20) is sleeved in the heating tube (1〇) and the hot tunnel body (10) has a reaming (21) at the top end for the plastic to pour; the body (20) And the heat bypass body (2Q) forms a ring wall (22) on the bottom edge, and the bottom end of the hot runner body (20) extends downwardly to a heat pipe (23) The bottom end of the tube (23) is provided with a closing member (2 4) for closing one end of the heat conducting tube (23). The heating coil (30) is provided on the outer diameter of the heating tube (1 〇). On the surface, the heating coil (30) is matched with the shape of the outer heating groove (12) of the heating pipe (10), so that the heating coil (30) can be embedded in the heating groove of the heating pipe (1〇) ( 12), as a heat source for heating plastics.
