Description

Technical Field

[0001] This utility model relates to the field of hot runner technology, and in particular to a novel heating copper sleeve. Background Technology

[0002] Hot runner nozzles are an important component of hot runners, and their function is to smoothly inject molten plastic material into the mold cavity.

[0003] Controlling the temperature of the heating copper sleeve on the nozzle is crucial. Originally, the temperature sensing wires were all on the nozzle copper sleeve body. Due to heat radiation loss, the actual temperature inside the nozzle would be slightly lower than the set temperature. When injection molding materials such as PBT+GF or PA66+GF, if the gate temperature does not meet the injection molding requirements, it will lead to defects on the product surface. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a new type of heating copper sleeve.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A novel heating copper sleeve includes: a temperature sensing ring, a copper sleeve mounted on the temperature sensing ring, a heating wire disposed on the copper sleeve, and a temperature sensing wire disposed within the temperature sensing ring and the copper sleeve; the temperature sensing point on the temperature sensing wire is disposed within the temperature sensing ring.

[0007] Preferably, the temperature sensing ring includes a buckle, a fixing ring for mounting the buckle, a wire groove formed in the fixing ring, and a fixing screw set on the fixing ring.

[0008] Preferably, the copper sleeve includes a cylindrical body; a limiting groove is formed on the outer side of the cylindrical body, a retaining groove is formed on the inner side, and a wire groove is provided on one side of the retaining groove; the heating wire is connected to the copper sleeve by being embedded in the limiting groove.

[0009] Compared with the prior art, this application has the following beneficial effects:

[0010] Compared with existing products, this utility model adds a temperature sensing ring structure and sets the temperature sensing point on the temperature sensing wire inside the temperature sensing ring. When the heating wire heats the copper sleeve, the copper sleeve will transfer heat to the temperature sensing point through the temperature sensing wire. During this process, due to the heat conduction factor, the copper sleeve will lose heat during the transfer. If the temperature at the temperature sensing point is lower than the required temperature, the heating wire needs to continue heating the copper sleeve until the temperature reflected by the temperature sensing point meets the actual required temperature. This design ensures that the temperature reflected by the temperature sensing point on the temperature sensing wire is the actual temperature on the copper sleeve, solving the problem that the gate temperature cannot meet the injection molding requirements.

[0018] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the features in the following embodiments can be combined with each other.

[0019] Example 1:

[0020] like Figure 1 As shown, a novel heating copper sleeve includes: a temperature sensing ring 10, a copper sleeve 20 mounted on the temperature sensing ring 10, a heating wire 30 disposed on the copper sleeve 20, and a temperature sensing wire 40 disposed within the temperature sensing ring 10 and the copper sleeve 20; the temperature sensing point on the temperature sensing wire 40 is disposed within the temperature sensing ring 10.

[0021] The existing product does not have a temperature sensing ring 10, so the entire temperature sensing wire 40 is installed inside the copper sleeve 20. When the temperature at the sensing point on the temperature sensing wire 40 is equal to the actual required temperature, the heating wire 30 stops heating. At this time, although the temperature reflected by the sensing point is equal to the actual required temperature, some heat is lost during heat conduction, resulting in the heating temperature on the copper sleeve 20 being lower than the actual required temperature. This leads to the gate temperature not meeting the injection molding requirements, which in turn causes defects on the product surface.

[0022] Compared with existing products, this new type of heating copper sleeve adds a temperature sensing ring 10 structure, and sets the temperature sensing point on the temperature sensing wire 40 inside the temperature sensing ring 10. When the heating wire 30 heats the copper sleeve 20, the copper sleeve 20 will transfer heat to the temperature sensing point through the temperature sensing wire 40. During this process, due to the factors of heat conduction, the copper sleeve 20 will lose heat during the transfer. If the temperature at the temperature sensing point is lower than the required temperature, the heating wire 30 needs to continue to heat the copper sleeve 20 until the temperature reflected by the temperature sensing point meets the actual required temperature. This design makes the temperature reflected by the temperature sensing point on the temperature sensing wire 40 the actual temperature on the copper sleeve 20, solving the problem that the gate temperature cannot meet the injection molding requirements.

[0023] like Figure 2 As shown, the temperature sensing ring 10 includes a buckle 11, a fixing ring 12 for mounting the buckle 11, a wire groove 13 formed in the fixing ring 12, and a fixing screw 14 set on the fixing ring 12.

[0024] The buckle 11 on the fixing ring 12 is a component used to connect with the copper sleeve 20. The temperature sensing ring 10 is installed on the copper sleeve 20 by snapping the buckle 11 into it. After installation, the temperature sensing ring 10 is fixed to the copper sleeve 20 by the fixing screw 14 on the fixing ring 12 to prevent the temperature sensing ring 10 from rotating or falling off.

[0025] Among them, the wire trough 13 is used to install part of the temperature sensing wire 40, and the temperature sensing wire 40 is provided with a temperature sensing point.

[0026] like Figure 3 As shown, the copper sleeve 20 includes a cylindrical body 21; a limiting groove 22 is provided on the outer side of the cylindrical body 21, and a slot 23 is provided on the inner side, with a wire groove 24 provided on one side of the slot 23; the heating wire 30 is connected to the copper sleeve 20 by embedding in the limiting groove 22.

[0027] The copper sleeve 20 is connected to the buckle 11 through the slot 23 inside the cylinder 21. When the buckle 11 is inserted and fastened in the slot 23, the copper sleeve 20 and the temperature sensing ring 10 are installed. The number and position of the slots 23 and the buckles 11 are one-to-one and can be determined according to actual needs, and there are no less than two pairs.

[0028] Among them, the second groove 24 is used to limit the installation of the rest of the temperature sensing wire 40.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.
