[0021] like Figures 1-5 As shown in the figure, an embodiment of the present invention provides a one-piece molding mold for a full-rimmed safety helmet, including an upper molding mold 1 and a lower molding mold 2. The lower side of the upper molding mold 1 is a molding concave surface 1-1. The lower molding mold 2 is provided with a molding core 3. An injection channel 4 is provided inside the lower molding mold 2 and the molding core 3. The upper end of the injection channel 4 passes through the highest point of the molding core 3. When the mold is closed, the upper molding mold 1 and the lower molding mold 2 are closed together. The molding core 3 is correspondingly located below the molding concave surface 1-1 and cooperates with the molding concave surface 1-1 to form a safety helmet molding cavity. The upper molding mold 1 is provided with mounting openings 1-2 on both sides corresponding to the safety helmet molding cavity. The 2-section has a side groove forming module 5, which is detachably connected to the upper mold 1 via a connecting component 7. The side wall has a protrusion 5-1 for cooperating with the molding core 3. During injection molding, the gating mechanism pours the molten material into the safety helmet molding cavity through the grouting channel 4. The molten material flows down from the highest point of the molding core 3, so that the molten material can complete the injection molding of the safety helmet according to the shape of the safety helmet molding cavity. The protrusion 5-1 on the side groove forming module 5 cooperates with the molding core 3, so that the side groove of the safety helmet is formed after grouting, without the need for secondary processing, thus improving processing efficiency.

[0022] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 6As shown, this embodiment also includes an upper mold base 6, which is fixed above the upper forming mold 1. The upper forming mold 1 has an installation port 1-3 corresponding to the installation port 1-2, and a vertical opening slot 1-4 corresponding to the installation port 1-3. The connecting component 7 includes a connecting block 8, a retaining strip 9, an upper connecting seat 10, and a lower connecting seat 11. The connecting block 8 is located in the installation port 1-3, and has an installation groove 8-1 and a retaining groove 8-2 on both sides. The installation groove 8-1 cooperates with the side groove forming module 5. The retaining groove 8-2 corresponds to the opening slot 1-4. The retaining strip 9 is retained in the retaining groove 8-2 and fixed to the upper connecting seat 10 by bolts. The upper connecting seat 10 can drive the retaining strip 9 to move along the retaining groove 8-2 and the opening slot 1-4. The lower connecting seat 11 is fixed to the upper forming mold 1 by bolts. The lower end of the upper connecting seat 10 has an abutment part. 10-1, the lower connecting seat 11 has a locking protrusion 11-1 corresponding to the abutment part 10-1; during assembly, one end of the side groove forming module 5 is inserted into the installation groove 8-1, and the connecting block 8 is placed in the installation opening 1-3. The upper connecting seat 10 can drive the locking strip 9 along the opening groove 1-4 to the locking groove 8-2 until the lower abutment part 10-1 engages with the locking protrusion 11-1 on the lower connecting seat 11. Then, the upper end of the upper connecting seat 10 is fixed to the upper mold base 6 with bolts. After the upper and lower ends of the upper connecting seat 10 are fixed, the protrusion 5-1 on the side groove forming module 5 abuts with the forming mold core 3, so that the side groove of the safety helmet is formed after grouting; during disassembly, the bolt connection between the upper connecting seat 10 and the upper mold base 6 is removed, and the upper connecting block 10, locking strip 9, connecting block 8, and the corresponding side groove forming module 5 can be taken out. The structure is simple and easy to disassemble and assemble.

[0023] Furthermore, such as Figure 1 , Figure 2 As shown, this embodiment also includes a lower mold base 12 and a demolding assembly 14. The lower mold base 12 is fixed below the lower molding mold 2 via a connecting post 13. The demolding assembly 14 includes a demolding seat 15 and multiple demolding ejector rods 16. The demolding seat 15 is located between the lower molding mold 2 and the lower mold base 12 and is slidably connected to the connecting post 13. The demolding ejector rods 16 are connected to the demolding seat 15 and slide through the lower molding mold 2 and the molding core 3. During injection molding, the demolding seat 15 fits against the upper wall of the lower mold base 12, and the upper end face of the demolding ejector rod 16 is adapted to the shape of the molding core 3. Each demolding ejector rod 16 cooperates with the molding core 3 and the molding concave surface 1-1 to form a safety helmet molding cavity. When it is necessary to demold the safety helmet, the demolding seat 15 is moved upward along the connecting post 13, which drives each demolding ejector rod 16 to move upward, thus completing the demolding of the safety helmet. The operation is simple.

[0024] Furthermore, such as Figure 1 , Figure 2 , Figure 7 , Figure 8As shown, the demolding base 15 in this embodiment includes an upper demolding template 15-1 and a lower demolding template 15-2. The upper demolding template 15-1 and the lower demolding template 15-2 are fixedly connected by bolts. The upper demolding template 15-1 is provided with multiple mounting ports 15-11 and a connecting seat 17 is provided in the mounting ports 15-11. The connecting seat 17 is provided with a snap-fit ​​groove 17-1 and is fixedly connected to the lower demolding template 15-2 by bolts. The lower end of the demolding ejector rod 16 is provided with a snap-fit ​​part 16-1. The demolding ejector rod 16 engages with the snap-fit ​​groove 17-1 through the snap-fit ​​part 16-1 at the lower end and can move up and down with the demolding base 15.

[0025] Furthermore, such as Figure 1 , Figure 2 , Figure 7 , Figure 8 , Figure 9 As shown, in this embodiment, the upper ejector plate 15-1 is provided with a plurality of guide posts 18, and the lower end of the guide post 18 is provided with a limiting ring 18-1. The upper ejector plate 15-1 is provided with a limiting ring groove that cooperates with the limiting ring 18-1. The guide post 18 can move up and down with the ejector base 15 to penetrate the lower mold 2. However, when the upper mold 1 and the lower mold 2 are closed, the lower end face of the upper mold 1 will restrict the upper end of the guide post 18 from penetrating the lower mold 2, thereby restricting the up and down movement of the ejector base 15 and ensuring injection molding during mold closing.

[0026] Furthermore, such as Figure 1 , Figure 2 As shown, in this embodiment, a locking member 19 is provided between the lower ejector platen 15-2 and the lower mold base 12. The lower ejector platen 15-2 has U-shaped holes 15-21 on both sides and multiple through holes 15-22 on the side of the U-shaped holes 15-21. The lower mold base 12 has U-shaped holes 12-1 corresponding to the U-shaped holes 15-21. The side wall of the U-shaped holes 12-1 has a limiting protrusion 12-2. The length of the U-shaped holes 12-1 is greater than that of the U-shaped holes 15-21. The locking member 19 has a pin 19-1 corresponding to the through holes 15-22 and a limiting groove 19-2 corresponding to the limiting protrusion 12-2 on the side wall. The locking member 19 is used to restrict the up and down movement of the ejector base 15, which further ensures the injection molding during mold closing.

[0027] Furthermore, such as Figure 1 , Figure 2 As shown, vertical plates 20 are provided on both sides between the lower forming mold 2 and the lower mold base 12 in this embodiment. The upper mold base 6, the upper forming mold 1, the lower forming mold 2, and the vertical plates 20 are fixedly connected into an integral structure by connecting column 21, which ensures the accuracy of mold closing.
