Detailed implementation manners

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] As Figure 1-9As shown in the figure, an injection mold of a large-angle angled slider mechanism includes an upper fixing plate 1, an upper template 2, a lower template 3 and a lower fixing plate 4. An upper mold core 5 and a lower mold core 6 that cooperates with the upper mold core 5 are arranged between the upper template 2 and the lower template 3. A first forming part 61 and a second forming part 62 are arranged on the lower mold core 6. The first forming part 61 is used for forming the body of the steering column switch a, and the second forming part 62 is used for forming the end part a2 of the main shaft a1 of the steering column switch a. There is a gap 63 between the first forming part 61 and the second forming part 62. A first movable insert 7 and a second movable insert 8 are arranged between the upper mold core 5 and the lower mold core 6 and at the position of the above-mentioned gap 63. Two opposite first movable inserts 7 are arranged, and the two first movable inserts 7 can move towards or away from each other in a direction perpendicular to the axis of the main shaft. Two second movable inserts 8 are also arranged and respectively form an inclined surface fit with the two first movable inserts 7. The two second movable inserts 8 are movably arranged along the axis of the main shaft. A first forming groove 71 is formed between the two first movable inserts 7, and a second forming groove 81 is formed between the two second movable inserts 8. A first receiving groove 64 for receiving the first movable insert 7 is arranged on the lower mold core 6. Sliding parts 72 are arranged on both sides of the first movable insert 7 located in the first receiving groove 64, and a guiding groove 65 that cooperates with the sliding parts 72 is arranged in the first receiving groove 64. A second receiving groove 66 for receiving the second movable insert 8 is arranged on the lower mold core 6. The side of the second movable insert 8 close to the first movable insert 7 forms a dovetail groove 82 fit with the first movable insert 7. A limiting groove 83 is arranged on the second movable insert 8, and a limiting rod 73 located in the limiting groove 83 is fixed or integrally arranged on the first movable insert 7. A vertical groove 74 is arranged on the first movable insert 7, and an inclined column 75 that urges the first movable insert 7 to slide relative to the lower mold core 6 is arranged in the vertical groove 74. An inclined strip-shaped hole 76 is arranged on the first movable insert 7, and an inclined guide post is inserted through the inclined strip-shaped hole 76.

[0025] By adopting the above technical solution, in the present utility model, the main innovation lies in the design of the structure of the lower die insert 6, the first movable insert 7 and the second movable insert 8, so as to realize the molding of the shift lever main shaft a1. Among them, the first molding portion 61 is used for molding the shift lever body a, the second molding portion 62 is used for molding the end portion a2 of the shift lever main shaft a1, and the combined setting of the first molding groove 71 and the second molding groove 81 can mold the component between the shift lever main shaft a1 and the end portion a2 of the shift lever main shaft a1. And after the molding of the shift lever main shaft a1 is completed, by moving the two first movable inserts 7 away from each other, the first movable inserts 7 are opened, and the two second movable inserts 8 are moved downward, so that the movement of the two inserts is completed, thus facilitating the ejection of the finished product. Among them, the first movable insert 7 and the second movable insert 8 are matched by inclined surfaces. While the first movable insert 7 slides, it can drive the second movable insert 8 to move, and the opening and closing movement of the first movable insert 7 and the up and down movement of the second movable insert 8 can have a relatively large movement stroke, so as to meet the molding requirements of the shift lever main shaft a1.
