Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0023] See also Figure 1-5 The utility model discloses a vehicle door glass groove front door A-pillar corner forming mold, comprising a lower mold 1 and an upper mold 2, the upper mold 2 being movably arranged on the top of the lower mold 1, the top of the lower mold 1 being provided with a floating plate 12 via a nitrogen spring 111, the top of the floating plate 12 being provided with an injection molding module 1 131 and an injection molding module 2 141 located on one side of the injection molding module 1 131, the injection molding module 1 131 and the injection molding module 2 141 forming an injection molding cavity 1, the top of the floating plate 12 being provided with an injection molding module 3 142 and an injection molding module 4 16 located on one side of the injection molding module 3 142, the injection molding module 3 142 and the injection molding module 4 16 forming an injection molding cavity 2.
[0024] Specifically, a fixed plate 11 is provided on the top of the lower mold 1, and the nitrogen spring 111 is provided on the top of the fixed plate 11. After the upper mold 2 and the lower mold 1 are opened, the nitrogen spring 111 is started to drive the floating plate 12 to rise, and all mold inserts above the floating plate 12 are lifted up by 30 mm, so that the bottom surface of the injection-molded part 5 after molding by the injection cavity 1 and the injection cavity 2 is separated from the bottom surface of the injection cavity 1 and the injection cavity 2 at the top of the fixed plate 11. Compared with the conventional oil cylinder lifting the floating plate 12, the setting of the nitrogen spring 111 allows the floating plate 12 to rise quickly under the action of the nitrogen spring 111, simplifying a complex oil cylinder mold opening action, which not only improves production efficiency, but also reduces mold development costs, while also meeting customer needs.
[0025] Specifically, a cylinder 13 is provided on the top of the floating plate 12, and the output end of the cylinder 13 is connected to one side of the injection molding module 131. The cylinder 13 is used to drive the injection molding module 131. When the floating plate 12 rises, the cylinder 13 is started to drive the injection molding module 131 to separate from the injection molded part 5.
[0026] Specifically, a cylinder 2 14 is provided on one side of the floating plate 12, and the output end of the cylinder 2 14 is transmission-connected to one side of the injection molding module 2 141 and the injection molding module 3 142. One side of the injection molding module 2 141 and the injection molding module 3 142 are both transmission-connected to the output end of the cylinder 2 14 through an inclined slider. The driving direction of the cylinder 2 14 is changed by the inclined slider, so that the injection molding module 2 141 and the injection molding module 3 142 are smoothly demolded. When the floating plate 12 rises, the cylinder 2 14 is started to drive the injection molding module 2 141 and the injection molding module 3 142 to separate from the injection molded part 5.
[0027] Specifically, a cylinder three 15 located on one side of the cylinder one 13 is provided on the top of the floating plate 12, and the output end of the cylinder three 15 is connected to one side of the injection molding module four 16. When the floating plate 12 rises, the cylinder three 15 is started to drive the injection molding module four 16 to separate from the injection molding part 5. When the injection molding module one 131, the injection molding module two 141, the injection molding module three 142 and the injection molding module four 16 are all separated from the injection molding part 5, the material after the secondary injection molding can be manually taken out.
[0028] Specifically, a cylinder four 18 is provided on the side of the floating plate 12 away from the cylinder two 14, a material feeding chute 17 is provided on the top of the floating plate 12, and the bottom is connected to the output end of the cylinder four 18, and a valve 19 for controlling the cylinder four 18 is provided on one side of the material feeding chute 17. A top strip groove material 3 and a vertical strip groove material 4 located on one side of the top strip groove material 3 are provided on the top of the floating plate 12. One end of the top strip groove material 3 extends to the interior of the injection cavity one, and the other end extends to the interior of the material feeding chute 17. The connection between the top strip groove material 3 and the vertical strip groove material 4 is located inside the injection cavity two. One end of the top strip groove material 3 and the top Injection molding parts 5 are provided between the strip groove material 3 and the vertical strip groove material 4. When in use, when loading, manually rotate the air valve 19 to control the cylinder four 18 to drive the material feeding slide 17 to retreat, manually clamp the top strip groove material 3 into the material feeding slide 17, rotate the air valve 19, and the cylinder four 18 drives the material feeding slide 17 to guide the top strip groove material 3 into the injection molding cavity and put it in place together. Manually insert the vertical strip groove material 4 into the injection molding cavity two and contact it with the top strip groove material 3, and carry out the next mold closing and injection molding. At this point, one production cycle is completed. After closing the upper mold 2 and the lower mold 1, the secondary injection molding can be carried out. Since the top strip groove material 3 is longer, the use of cylinder four 18 for mold insertion greatly improves efficiency.
[0029] In summary, the car door glass groove front door A-pillar corner forming mold cancels the previous cylinder action of the mold rising floating plate 12 and adds a nitrogen spring 111 instead. After the injection molding is completed and the equipment mold is opened, the floating plate 12 rises quickly under the action of the nitrogen spring 111, simplifying a complex cylinder mold opening action, which not only improves production efficiency, but also reduces mold development costs, while also meeting customer needs. The top strip groove material 3 is controlled by the cylinder four 18 to complete the mold insertion, realizing rapid assembly and disassembly, reducing the labor intensity of workers to the greatest extent, and improving processing efficiency.
