Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 , Figure 3 and Figure 4 The utility model provides an embodiment: an injection mold for modified plastic sofa parts, comprising a workbench 1, a workbench 1, a bracket 2 is fixedly connected to the middle outer side of the top surface of the workbench 1, a first telescopic rod 3 is fixedly connected to the middle outer side of the bottom surface of the workbench 1, the output end of the first telescopic rod 3 is fixedly connected to a lower support plate 4, a lower mold 5 is fixedly connected to one side of the lower support plate 4, a lower ejector rod 6 is fixedly connected to the middle of the top surface of the workbench 1, a top plate 7 is fixedly connected to the top of the lower ejector rod 6, the top plate 7 is at the inner bottom of the lower mold 5, and the lower ejector rod 6 is slidably connected to the lower mold 5, a second telescopic rod 8 is fixedly connected to the middle outer side of the top surface of the bracket 2, an upper support plate 9 is fixedly connected to the output end of the second telescopic rod 8, an upper support plate 9 is fixedly connected to one side of the upper support plate 9, an upper mold 10 is slidably connected to the middle of the upper mold 10, and an upper ejector rod 11 is fixedly connected to the middle of the top surface of the inner wall of the bracket 2, and a cooling component is arranged at the bottom of the workbench 1.

[0032] When in use, the first telescopic rod 3 and the second telescopic rod 8 are driven to extend the output end so that the upper mold 10 and the lower mold 5 are attached together, and then the modified plastic is added to the interior of the upper mold 10 and the lower mold 5. When the modified plastic is cooled and formed, the first telescopic rod 3 and the second telescopic rod 8 are driven to retract the output end to drive the lower mold 5 and the upper mold 10 to move away from each other. At this time, the upper mold 10 and the upper ejector rod 11, and the lower mold 5 and the lower ejector rod 6 can slide against each other, and the upper ejector rod 11 is installed on the bracket 2, and the lower ejector rod 6 is installed on the workbench 1, and the top plate 7 is at the inner bottom of the lower mold 5. Therefore, when the upper mold 10 and the lower mold 5 are away from each other, the upper ejector rod 11 and the top plate 7 can be used to limit the movement of the modified plastic, thereby separating it from the upper mold 10 and the lower mold 5, thereby achieving the purpose of demoulding, thereby preventing the electric telescopic rod and the electric pusher from being scalded.

[0033] Reference Figure 3 The cooling assembly includes a water pump 12, a water inlet pipe 13 and a water outlet pipe 14. The water pump 12 is fixedly connected to the bottom surface of the workbench 1, the bottom of the water inlet pipe 13 is fixedly connected to the output end of the water pump 12, the top of the water inlet pipe 13 is fixedly connected to one side of the bottom of the lower mold 5, and the water outlet pipe 14 is fixedly connected to the other side of the bottom of the lower mold 5. A cavity is provided inside the lower mold 5, and the water inlet pipe 13, the water outlet pipe 14 and the cavity are connected to each other.

[0034] By connecting the water source to the input end of the water pump 12, the water can be transported to the cavity inside the lower mold 5 along the water inlet pipe 13 by driving the water pump 12, and the lower mold 5 can be cooled at this time, thereby accelerating the cooling rate of the modified plastic.

[0035] Reference Figure 1 A third telescopic rod 15 is fixedly connected to the middle of the top surface of the bracket 2, a mounting plate 16 is fixedly connected to the output end of the third telescopic rod 15, a feed pipe 17 is fixedly connected to the middle of the mounting plate 16, and the feed pipe 17 is located directly above the upper mold 10. A through hole is opened in the middle of the bracket 2, and the feed pipe 17 is located inside the through hole. A feed port is opened at the top of the upper mold 10.

[0036] By driving the third telescopic rod 15 to extend out of the output end, the mounting plate 16 can be driven to move downward, and then the feed pipe 17 can be driven to move downward and close to the through hole in the middle of the upper mold 10. At this time, the modified plastic can be injected into the interior of the upper mold 10 and the lower mold 5 through the feed pipe 17.

[0037] Reference Figure 1 , Figure 2 and Figure 3 A guide rod 18 is fixedly connected to the outer side of the middle part of the bottom surface of the bracket 2, and the bottom of the guide rod 18 is fixedly connected to the top surface of the workbench 1. The mounting plate 16, the upper support plate 9 and the lower support plate 4 are all slidably connected to the outer side of the guide rod 18.

[0038] The guide rod 18 can simultaneously guide the movement directions of the upper mold 10, the lower mold 5 and the mounting plate 16, thereby improving the accuracy of the relative position between the upper mold 10 and the lower mold 5, thereby ensuring the production quality of the sofa parts.

[0039] Working principle: When in use, the first telescopic rod 3 and the second telescopic rod 8 are driven to extend out of the output end, and the lower mold 5 and the upper mold 10 can be driven to approach the middle of the bracket 2 respectively. When the upper mold 10 and the lower mold 5 are attached together, the third telescopic rod 15 is driven to extend out of the output end, and the mounting plate 16 can be driven to move downward, and then the feed pipe 17 can be driven to move downward and approach the through hole in the middle of the upper mold 10. At this time, the modified plastic can be added to the interior of the upper mold 10 and the lower mold 5 through the feed pipe 17. When the modified plastic enters between the upper mold 10 and the lower mold 5, the third telescopic rod 15 is driven to retract the output end, and the feed pipe 17 is driven to move upward away from the upper mold 10. Then the water source is connected to the input end of the water pump 12, and the water can be pumped along the water inlet pipe 1 by driving the water pump 12. 3 is transported to the cavity inside the lower mold 5, at which time the lower mold 5 can be cooled, thereby accelerating the cooling rate of the modified plastic, and when the modified plastic is cooled and formed, the first telescopic rod 3 and the second telescopic rod 8 are driven to retract the output end, thereby driving the lower mold 5 and the upper mold 10 to move away from each other, and at this time, the upper mold 10 and the upper ejector rod 11, and the lower mold 5 and the lower ejector rod 6 can slide against each other, and the upper ejector rod 11 is installed on the bracket 2, and the lower ejector rod 6 is installed on the workbench 1, and the top plate 7 is at the inner bottom of the lower mold 5, so when the upper mold 10 and the lower mold 5 are away from each other, the upper ejector rod 11 and the top plate 7 can be used to limit the movement of the modified plastic, thereby separating it from the upper mold 10 and the lower mold 5, thereby achieving the purpose of demoulding.
