[0030] The present invention will be further described below with reference to the accompanying drawings.

[0031] like Figures 1-9 As shown, an injection molding mold for the tabletop of a climbing dormitory bed includes a lower mold base 1 and an upper mold base 2. Two mold frames 3 are symmetrically fixedly connected to the upper side wall of the lower mold base 1. The same lower mold 4 is fixedly connected to the upper side of the two mold frames 3. An upper template 5 is fixedly connected to the lower side wall of the upper mold base 2. An upper mold 6 is fixedly connected to the lower side wall of the upper template 5. A panel concave mold cavity 7 is provided inside the lower mold 4. A demolding component is fixedly connected to the lower mold 4. A gating system is provided between the upper mold base 2, the upper template 5 and the upper mold 6.

[0032] The gating system includes a conical gate 8 fixedly embedded in the middle of the upper mold base 2 and the upper mold plate 5. The upper mold 6 has a main runner 9 located in the middle of the upper mold 6. The upper side wall of the upper mold 6 has multiple arc-shaped branch runners 10, which are evenly distributed on both sides of the main runner 9 and are connected to the main runner 9. The upper mold 6 has multiple gating holes 11 connected to the multiple arc-shaped branch runners 10. The gating holes 11 are located at the ends of the arc-shaped branch runners 10 away from the main runner 9. The lengths of the multiple arc-shaped branch runners 10 are different, and the width of the arc-shaped branch runners 10 gradually increases from the main runner 9 to the gating holes 11.

[0033] In this embodiment, during injection molding of the edge sealing, the mold is closed, and molten raw material is injected into the conical gate 8. The molten raw material flows downward through the conical gate 8 into the main runner 9. Multiple arc-shaped branch runners 10 branching off from both sides of the main runner 9 can quickly divert the molten raw material. The multiple arc-shaped branch runners 10 can transport the raw material to multiple injection holes 11. Since the multiple injection holes 11 are distributed at different positions above the panel concave mold cavity 7, the raw material can be injected into the panel concave mold cavity 7 from multiple positions. Furthermore, the different lengths of the multiple arc-shaped branch runners 10 can increase the coverage area, and the gradually widening width of the arc-shaped branch runners 10 can avoid blockage. This improves the smoothness of the injection molding of the ladder-style dormitory bed tabletop edge sealing mold and effectively improves the processing efficiency of the ladder-style dormitory bed tabletop injection molding edge sealing mold.

[0034] The lower mold 4 has a fixedly connected positioning top mold hole 12 on its vertical side wall. The positioning top mold hole 12 is evenly distributed on the four vertical side walls of the lower mold 4, which facilitates the fixing and positioning of the lower mold 4 and improves the stability of the mold.

[0035] The demolding assembly includes multiple guide rods 13 fixedly connected to the lower side of the lower mold 4. The same demolding template 14 is movably sleeved on the multiple guide rods 13. Multiple demolding ejector rods 15 are fixedly connected to the demolding template 14. Multiple demolding holes are opened on the lower mold 4. The upper end of the demolding ejector rod 15 is movably inserted into the demolding hole. Multiple holes 16 corresponding to the demolding ejector rods 15 are opened at the bottom of the lower mold base 1.

[0036] In the above embodiment, the demolding template 14 is pushed to move upward, and the demolding template 14 drives multiple demolding ejector pins 15 to move upward. The demolding ejector pins 15 can push the formed panel upward to complete the demolding.

[0037] The upper side wall of the lower mold 4 is fixedly embedded with a plurality of first positioning blocks 17, and the lower side wall of the upper mold 6 is fixedly embedded with a plurality of second positioning blocks 18 that match the first positioning blocks 17.

[0038] In this embodiment, the first positioning block 17 and the second positioning block 18 cooperate with each other to improve the accuracy of mold closing and improve the forming precision of the mold.

[0039] Guide posts 19 are fixedly connected to the four corners of the upper side of the lower mold 4, and guide sleeves 20 are fixedly connected to the four corners of the upper mold base 2, the upper template 5 and the upper mold 6. The guide sleeves 20 are movably sleeved on the guide posts 19.

[0040] In this embodiment, the guide post 19 and the guide sleeve 20 cooperate with each other to improve the smoothness of mold opening and closing.

[0041] Grooves 21 are provided at the four corners of the lower side of the upper mold 6 and the four corners of the upper side of the lower mold 4.

[0042] In the above embodiments, the multiple grooves 21 provided can improve the ease of separation between the lower mold 4 and the upper mold 6.

[0043] The template 14 includes an upper plate 22 and a lower plate 23, which are fixedly connected by a plurality of bolts 24.

[0044] In the above embodiments, the upper plate 22 and lower plate 23 can improve the stability of the connection between the demolding template 14 and the demolding ejector pin 15.

[0045] The lower mold 4 has multiple positioning posts 25 fixedly connected to its upper side wall, and the upper mold 6 has multiple positioning grooves 26 corresponding to the positioning posts 25 on its lower side.

[0046] In this embodiment, the positioning pin 25 and the positioning groove 26 cooperate with each other to improve the accuracy of the mold closing between the lower mold 4 and the upper mold 6, thereby improving the quality of the panel molding.

[0047] The inner walls of the multiple arc-shaped branch channels 10 are all polished, which can improve the smoothness of the material flow within the arc-shaped branch channels 10.

[0048] The tapered gate 8 is fixedly connected to the upper mold base 2 by multiple locking screws 27.

[0049] In the above embodiment, the multiple locking screws 27 provided can improve the stability of the tapered gate 8.

[0050] The working principle of this utility model is as follows:

[0051] During injection molding edge sealing, the mold is closed, and molten raw material is injected into the conical gate 8. The molten raw material flows downward through the conical gate 8 into the main runner 9. Multiple arc-shaped branch runners 10 branching off from both sides of the main runner 9 can quickly divert the molten raw material. The multiple arc-shaped branch runners 10 can transport the raw material to multiple injection holes 11. Since the multiple injection holes 11 are distributed at different positions above the panel concave mold cavity 7, the raw material can be injected into the panel concave mold cavity 7 from multiple positions. After the raw material in the panel concave mold cavity 7 cools, it will form the panel. The mold is then opened, and demolding is performed through the demolding component to complete the rapid injection molding edge sealing of the ladder apartment bed tabletop, effectively improving the processing efficiency of the injection molding edge sealing mold for the ladder apartment bed tabletop.
