Description

Technical Field

[0001] The utility model mainly relates to the technical field of hot runner heaters, in particular to a novel magnesium alloy nozzle heater. Background Art

[0002] The principle of the hot runner heater: When thicker metal is in an alternating magnetic field, it will generate current due to electromagnetic induction. After the thicker metal generates current, the current will form a spiral flow path inside the metal. In this way, the heat generated by the flow of current will be absorbed by the metal itself, causing the metal to heat up quickly.

[0003] The existing hot runner heater has only one heating wire, and the overall heating temperature is consistent. The excessively high temperature near the nozzle will cause energy waste. On the other hand, when heating the magnesium alloy nozzle, since the heating temperature of the magnesium alloy nozzle is higher than that of the injection molding machine, the overall load is large and the service life is short.

[0017] To facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0018] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "page", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0019] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0020] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed", "provided with", etc. should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Example

[0021] See attached Figure 1 A novel magnesium alloy nozzle heater comprises a tube body 1, on which a spiral heating wire 2 is wound. The number of the heating wires 2 is several and evenly distributed along the axis direction of the tube body 1. Both ends of the heating wire 2 are equipped with power lines 3.

[0022] In this embodiment, after the power cord 3 is connected to the power supply, the heating wire 2 can be energized to generate a magnetic field so that the tube body 1 heats the magnesium alloy nozzle. There are several heating wires 2, and the power cord 3 can be connected to voltages of different loads to achieve different degrees of heating effects, so that the heating temperature gradually decreases from the nozzle mouth downward, thereby avoiding energy waste.

[0023] The two power cords 3 are respectively equipped with a series socket 4 and a serial plug 5 , and the two power cords 3 are respectively installed at the ends of two adjacent heating wires 2 .

[0024] In this embodiment, after the series socket 4 and the serial flow plug 5 are connected, two adjacent heating wires 2 can be connected in series. Similarly, all the heating wires 2 can be connected in series, so that the heating load can be distributed to each heating wire 2, thereby increasing the overall temperature, and effectively reducing the load of a single heating wire 2 and extending its service life.

[0025] The outer wall of the tube body 1 is provided with a pre-buried groove 101, and the heating wire 2 is fitted and embedded in the pre-buried groove 101, so as to reduce space occupation and improve the heating effect.

[0026] The side wall of the tube body 1 is provided with a thread groove 102 , which is communicated with the inside of the tube body 1 . There are two thread grooves 102 symmetrically distributed up and down.

[0027] When the radius of the magnesium alloy nozzle to be heated is small, a screw is installed in the thread groove 102 so that the end of the screw abuts against the outer wall of the magnesium alloy nozzle, thereby achieving installation, thereby being applicable to magnesium alloy nozzles of different radius specifications.

[0028] The above-described embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the patent of the utility model shall be based on the attached claims.

[0029] It should be noted that the above contents belong to the technical cognition scope of the inventor. Since the technical contents in this field are vast and too complicated, the above contents of this application do not necessarily constitute prior art.
