The terms used in the specification of the present utility model are only for the purpose of describing specific embodiments and are not used to limit the present utility model.
[0028] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.
[0029] Now, with reference to the accompanying drawings, a further description of the effective embodiments of the present invention will be given. Figure 1 and Figure 2 As shown, the circular glue outlet hot runner includes a glue inlet pipe 100 and a dispensing body 200. One end of the dispensing body 200 is provided with a glue inlet 210, and the glue inlet 210 is connected to the glue inlet pipe 100. At the end of the dispensing body 200 far from the glue inlet pipe 100, a plurality of glue outlet members 300 are provided. The glue outlet members 300 are arranged at intervals according to a preset distance on the end face of the dispensing body 200 far from the glue inlet pipe 100. A plurality of dispensing pipes 220 connecting the glue inlet 210 and the glue outlet members 300 are arranged in the dispensing body 200. A separating member 230 is arranged between the glue outlet members 300, and the separating member 230 is integrally formed with the dispensing body 200. A glue outlet nozzle 310 is arranged on the side of the glue outlet member 300 facing the outside of the dispensing body 200, and a tightening member 400 is arranged on the reverse side of the glue outlet nozzle 310. When the liquid glue passes through the glue inlet pipe 100 and flows into the dispensing body 200 from the glue inlet 210, it will be split by the dispensing pipes 220 and then flow into different glue outlet members 300 respectively, and then flow out from the glue outlet nozzle 310. Compared with the existing multi-channel hot runner system, first, the glue inlet pipe 100 and the dispensing body 200 of the present application are installed in a split manner. When the hot runner is damaged or worn, there is no need to replace the entire hot runner system, and only the damaged parts need to be replaced separately, which reduces the maintenance cost and time. Second, the glue outlet members 300 of the present application are arranged between the separating members 230. When the glue outlet members 300 are damaged, only the glue outlet members 300 need to be taken out from the separating members 230, and there is no need to disassemble the entire hot runner system, making the replacement of the glue outlet members 300 more convenient.
[0030] Furthermore, on the basis of the above embodiment, as shown in Figure 2 and Figure 3 A fixing screw 320 is arranged inside the glue outlet member 300. The fixing screw 320 passes through the glue outlet member 300 from the top of the glue outlet member 300 to fix the glue outlet member 300 on the end face of the dispensing body 200. Since both sides of the glue outlet member 300 are clamped by the separating member 230, when it is necessary to disassemble the glue outlet member 300, the fixing screw 320 needs to be loosened from the top of the glue outlet member 300, and then the disassembly between the glue outlet member 300 and the end face can be realized. In this way, compared with the prior art, there is no need to open the hot runner system from the top to complete the disassembly of the glue outlet member 300.
[0031] Furthermore, on the basis of the above embodiment, as shown in Figure 2 and Figure 3As shown, a nozzle core sleeve 330 is sleeved on the glue outlet nozzle 310. The function of the nozzle core sleeve 330 is to prevent the glue from overflowing from both sides of the glue outlet nozzle 310 when the glue flows out of the glue outlet nozzle 310, thus causing glue leakage, as Figure 5 shown, when sleeving the nozzle core sleeve 330 on the glue outlet nozzle 310, a force perpendicular to the end face of the glue outlet is applied to the glue outlet nozzle 310. At this time, since a wedging member 400 is provided on the reverse side of the glue outlet nozzle 310, when sleeving the nozzle core sleeve 330, the wedging member 400 will support the glue outlet nozzle 310 on the reverse side, so that the nozzle core sleeve 330 can be more firmly sleeved on the glue outlet nozzle 310, thereby reducing the occurrence of glue leakage.
[0032] Furthermore, on the basis of the above embodiments, such as in combination with Figure 2 and Figure 4 shown, the wedging member 400 is annular, including a fixed part 410 and an abutting part 420 arranged at intervals. The fixed part 410 is fixed on the end face of the sub-colloid 200 through a fixing screw 320, and the abutting part 420 abuts against the side of the glue outlet nozzle 310 away from the glue outlet nozzle 310.
[0033] In some embodiments, as Figure 2 shown, heating wires 240 are provided on the side walls of the sub-colloid 200 and the separator 230. In this way, when the glue flows into the sub-colloid 200 from the glue inlet 210 and then is split by the glue splitting tube 220 and flows into different glue outlet members 300 respectively, the heating wires 240 can heat the side walls of the sub-colloid 200 and the separator 230, so as to ensure that the glue can maintain a flowing state during the above process.
[0034] In some embodiments, as Figure 6 shown, on the end face of the side of the sub-colloid 200 away from the separator 230, a plurality of connecting rods 250 are arranged at preset intervals. The connecting rods 250 are used to fix the sub-colloid 200 on the injection mold. An insulating spacer 251 is sleeved around the connecting rods 250. The insulating spacer 251 can reduce the heat transferred from the sub-colloid 200 to other parts of the injection mold, reduce the heat loss of the sub-colloid 200, improve the energy utilization efficiency, and protect other temperature-sensitive parts in the injection mold.
[0035] Furthermore, on the basis of the above embodiments, such as Figure 6 shown, a heating tube 110 is sleeved on the glue inlet tube 100. The heating tube 110 is used to heat the glue inlet tube 100 when the glue passes through the glue inlet tube 100, so as to ensure that the glue can maintain a flowing state during the above process.
[0036] In some embodiments, such asFigure 6 As shown, a sprue bushing 500 is connected between the glue inlet pipe 100 and the dispensing colloid 200. The sprue bushing 500 can control the speed and flow rate of the colloid entering the dispensing colloid 200, thereby affecting the molding quality of the product. At the same time, it can withstand the high pressure generated by the ejection of the colloid from the glue inlet pipe 100 and prevent deformation or damage to the connection between the glue inlet pipe 100 and the dispensing colloid 200.
[0037] In some embodiments, as Figure 6 shown, an insert 120 is also sleeved outside one end of the glue inlet pipe 100 away from the dispensing colloid 200. Since one end of the glue inlet pipe 100 away from the dispensing colloid 200 is directly connected to the glue making machine and bears the greatest liquid pressure, sleeving the insert 120 outside it can enable the glue inlet pipe 100 to bear greater pressure and friction, and extend the service life of the glue inlet pipe 100.
[0038] Details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, in any regard, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be encompassed within the present invention.
