[0002] The hot runner is an advanced technology and system in injection molds. It keeps the plastic in a molten state in the runner by heating, so as to more efficiently and precisely transport the plastic melt into the mold cavity for injection molding.
[0003] In the existing hot runner system, the glue inlet pipe and the distributor are usually integrally formed. When problems occur with the glue inlet pipe and the distributor, the whole needs to be disassembled, which is very time-consuming and laborious. Secondly, the nozzle core is a very easily damaged component for the hot runner. However, in the existing structure, the nozzle core is usually installed inside the distributor. If the nozzle core is damaged, the whole distributor also needs to be disassembled, which brings great inconvenience to enterprises. Summary of the Utility Model
[0004] To solve the above problems, the utility model provides a square glue discharging hot runner, including a glue inlet and a distributor. One end of the distributor is provided with a glue inlet, which is connected to a glue inlet pipe. Two support plates are provided at the end of the distributor far from the glue inlet pipe. The support plates are arranged oppositely, and a receiving groove is formed between them. A glue outlet and a glue discharging member are arranged between the receiving grooves. The glue discharging member is relatively fixedly arranged on the distributor and is connected to the glue outlet. A nozzle core is arranged on the glue discharging member. The nozzle core passes through the support plate. A tightening member is arranged between the two opposing glue discharging members, and the tightening member is used to press the glue discharging member against one side of the support plate.
[0005] Furthermore, a fixing screw is arranged inside the glue discharging member. The fixing screw passes through the top of the glue discharging member and fixes the glue discharging member on the end face of the distributor.
[0006] Furthermore, a plurality of through holes are arranged on the support plate. The nozzle core of the glue discharging member passes through the through holes of the support plate and extends outwards.
[0007] Furthermore, a nozzle sleeve is sleeved on the nozzle core, and the nozzle sleeve is pressed against the side of the through hole far from the tightening member.
[0008] Furthermore, the width of the tightening member is greater than the distance between the opposing glue discharging members.
[0009] Furthermore, an inclined first contact surface is arranged on the side of the glue discharging member far from the support member. Inclined second contact surfaces are arranged on both sides where the tightening member contacts the glue discharging member.
[0010] Furthermore, a fixing screw is also arranged inside the wedging member, and the fixing screw passes through the top of the wedging member and fixes the wedging member on the end face of the dispensing colloid.
[0011] Furthermore, a heating wire is arranged on the side wall of the dispensing colloid.
[0012] Furthermore, an insert is sleeved outside one end of the dispensing colloid away from the glue discharging member.
[0013] Furthermore, the shape of the nozzle core is conical.
[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0015] Compared with the existing multi-channel hot runner system, firstly, the glue inlet pipe and the dispensing colloid 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, reducing the maintenance cost and time. Secondly, when fixing the glue discharging member on the dispensing colloid, there is no need for a gland, but the glue discharging member is directly fixed at one end of the dispensing colloid, and then the wedging member is used to press the glue discharging member against the support plate. In this way, when the glue discharging member is damaged, only the glue discharging member needs to be loosened to take it out. On the basis of ensuring that the glue discharging member does not leak glue, the steps of replacing the glue discharging member are greatly simplified. BRIEF DESCRIPTION OF THE DRAWINGS

The terms used in the description of the present invention are only for the purpose of describing specific embodiments and are not used to limit the present invention.
[0027] 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.
[0028] The preferred embodiments of the present utility model will now be further described in conjunction with the accompanying drawings. Figure 1 and Figure 3 As shown, the square glue-out hot runner includes a glue inlet pipe 100 and a distributor body 200. One end of the distributor body 200 is provided with a glue inlet 210, and the glue inlet 210 is connected to the glue inlet pipe 100. Two support plates 220 are provided at the end of the distributor body 200 away from the glue inlet pipe 100. The support plates 220 are arranged oppositely, and a receiving groove 230 is formed between the support plates 220. A glue outlet 240 and a glue-out member 250 are provided between the receiving grooves 230. The glue-out member 250 is relatively fixedly arranged on the distributor body 200 and is connected to the glue outlet 240. A nozzle core 251 is provided on the glue-out member 250, and the nozzle core 251 passes through the support plate 220. A tightening member 300 is provided between the two opposed glue-out members 250. The tightening member 300 is used to press the glue-out member 250 against one side of the support plate 220. When the liquid colloid passes through the glue inlet pipe 100 and flows into the distributor body 200 from the glue inlet 210, it will be split by the distributor body 200 and flow out from different glue outlets 240, and then flow into different glue-out members 250 respectively, and then flow out from the nozzle core 251. Compared with the existing multi-channel hot runner system, firstly, the glue inlet pipe 100 and the distributor 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. Secondly, when fixing the glue-out member 250 on the distributor body 200 in the present application, there is no need for a gland, but the glue-out member 250 is directly fixed at one end of the distributor body 200, and then the tightening member 300 is used to press the glue-out member 250 against the support plate 220. In this way, when the glue-out member 250 is damaged, only the glue-out member 250 needs to be loosened to take it out. In this way, on the basis of ensuring that the glue-out member 250 does not leak glue, the steps of replacing the glue-out member 250 are greatly simplified.
[0029] Furthermore, on the basis of the above embodiments, as Figure 3 and Figure 4 shown, a fixing screw 260 is provided inside the glue-out member 250. The fixing screw 260 passes through the glue-out member 250 from the top of the glue-out member 250 to fix the glue-out member 250 on the end face of the distributor body 200. Therefore, when the glue-out member 250 needs to be disassembled, the fixing screw 260 needs to be loosened from the top of the glue-out member 250 to realize the disassembly between the glue-out member 250 and the end face. In this way, compared with the prior art, there is no need to open the gland of the hot runner system from the top to complete the disassembly of the glue-out member 250.
[0030] In some embodiments, in combination with Figures 2 to 4 As shown, a plurality of through holes 221 are provided on the support plate 220. The nozzle core 251 of the glue discharging member 250 passes through the through holes 221 and protrudes outward from the support plate 220. Further, on the basis of the above embodiments, a nozzle sleeve 252 is sleeved on the nozzle core 251. The nozzle sleeve 252 is pressed against the side of the through hole 221 away from the wedging member 300. The function of the nozzle sleeve 252 is to prevent the glue from overflowing from the periphery of the nozzle core 251 when the glue flows out of the nozzle core 251, thus causing glue leakage. Secondly, since the nozzle sleeve 252 is pressed against the side of the through hole 221 away from the wedging member 300, when the nozzle sleeve 252 is sleeved on the nozzle core 251, a force perpendicular to the support plate 220 will be applied to the nozzle core 251. At this time, since the wedging member 300 is provided on the reverse side of the nozzle core 251, when the nozzle sleeve 252 is sleeved, the wedging member 300 will support the nozzle core 251 on the reverse side, so that the nozzle sleeve 252 can be more firmly sleeved on the nozzle core 251, thereby reducing the occurrence of glue leakage.
[0031] Further, on the basis of the above embodiments, as Figure 4 shown, the width of the wedging member 300 is greater than the distance between the opposing glue discharging members 250. In this way, when the wedging member 300 is inserted between the opposing glue discharging members 250, an interference fit will be generated between the two, thereby pressing the glue discharging member 250 against one side of the support plate 220.
[0032] Further, on the basis of the above embodiments, as Figure 4 shown, an inclined first contact surface 253 is provided on the side of the glue discharging member 250 away from the support member. Inclined second contact surfaces 310 are provided on both sides of the wedging member 300 in contact with the glue discharging member 250. This can make the wedging member 300 more smoothly inserted between the opposing glue discharging members 250, so as to form an interference fit between the above two.
[0033] Further, on the basis of the above embodiments, as Figure 4 shown, a fixing screw 260 is also provided inside the wedging member 300. The fixing screw 260 passes through the top of the wedging member 300 to fix the wedging member 300 on the end surface of the dispensing colloid 200. Therefore, when the wedging member 300 needs to be disassembled, the fixing screw 260 needs to be loosened from the top of the wedging member 300 to achieve the disassembly between the wedging member 300 and the end surface.
[0034] In some embodiments, as Figure 1As shown in the figure, a heating wire 270 is provided on the side wall of the sub-colloid 200. In this way, after the colloid flows into the sub-colloid 200 from the glue inlet 210, it is split by the sub-colloid 200 and flows out from different glue outlets 240, and then flows into different glue outlet parts 250 respectively. During this process, the heating wire 270 can heat the side wall of the sub-colloid 200, so as to ensure that the colloid can maintain a fluid state during the above process.
[0035] In some embodiments, as Figure 1 shown in the figure, an insert 280 is also sleeved outside one end of the sub-colloid 200 away from the glue outlet part 250. Since one end of the sub-colloid 200 away from the glue outlet part 250 is directly connected to the glue making machine and bears the maximum liquid pressure, sleeving the insert 280 outside it can enable the sub-colloid 200 to bear greater pressure and friction, and extend the service life of the sub-colloid 200.
[0036] Furthermore, on the basis of the above embodiments, as Figure 1 and Figure 4 shown in the figure, the shape of the nozzle core 251 is conical, so that when the colloid flows out of the nozzle core 251, it can flow out more concentratedly.
[0037] 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 included in the present invention.
