[0002] New energy vehicles refer to vehicles that use unconventional automotive fuels as their power source, including pure electric vehicles, hybrid vehicles, etc. Most new energy vehicles on the market now require a special charger to charge the in-car power supply.

[0003] When producing charging heads for new energy vehicles, it is necessary to use molds to stamp the raw materials of the charging heads. When loading the existing charging head molds, most of the raw materials are transferred by a conveyor belt and directly fall on the top of the lower mold. However, in the prior art, after the conveyor belt is used for transmission, the raw materials cannot be directly aligned with the molding cavity of the lower mold after falling on the top of the lower mold. This leads to material shortages at the corners of the raw materials and the molding cavity of the lower mold during stamping, resulting in missing corners of the charging head shell after molding, and a large amount of waste.

[0004] Therefore, a new energy vehicle charging head mold is proposed to solve the above problems. Utility Model Content

[0028] Example:

[0029] See also Figure 1 - Figure 4A new energy vehicle charging head mold includes a lower mold 1, a proofreading mechanism 2 is arranged inside the lower mold 1, the proofreading mechanism 2 includes a cylinder 21 arranged on one side of the lower mold 1 and a gear 23 rotatably connected to the top of the inner wall of the lower mold 1, the telescopic end of the cylinder 21 is fixedly connected with a rack 22, the rack 22 is meshed with the gear 23, and the bottom of the gear 23 is fixedly connected with a cam 24, and a sliding limit plate 25 is slidably arranged on the bottom surface of the inner wall of the lower mold 1, and two rotating rods 26 are rotatably connected to the top surface of the sliding limit plate 25 and near one side edge, and the ends of the two rotating rods 26 away from the sliding limit plate 25 are rotatably connected with a movable plate 27.

[0030] Specifically, the two rotating rods 26 are symmetrically arranged on the top surface of the sliding limiting plate 25 , and the two movable plates 27 are symmetrically arranged outside the lower mold 1 .

[0031] Specifically, a through hole No. 11 is formed through one side of the lower mold 1 , and the telescopic end of the cylinder 21 is slidably connected to the inside of the through hole No. 11 .

[0032] Specifically, the bottom surface of the inner wall of the lower mold 1 is fixedly connected with the slide rail 12 , and the sliding limit plate 25 is slidably connected to the top surface of the slide rail 12 .

[0033] Specifically, two No. 2 through holes 13 are formed through both sides of the lower mold 1 , and the two movable plates 27 are slidably connected to the two No. 2 through holes 13 , respectively.

[0034] In this solution, the proofreading mechanism 2 is used to correct the position of the raw material above the lower mold 1, which can effectively improve the molding effect of the mold. The cylinder 21 is used to push the rack 22 to move inside the lower mold 1. When the rack 22 moves, it will drive the gear 23 meshing with it to rotate, thereby rotating the cam 24. After the cam 24 rotates, its protrusion will abut against one side of the sliding limit plate 25, thereby causing the sliding limit plate 25 to slide on the slide rail 12. As the gear 23 continues to rotate, the sliding limit plate 25 is in a reciprocating sliding motion state inside the lower mold 1. During the sliding of the sliding limit plate 25, the two movable plates 27 can be continuously pulled by the rotating rod 26. Due to the limiting effect of the two No. 2 through holes 13, the two movable plates 27 will continuously move toward or away from each other on both sides of the lower mold 1, thereby continuously clamping and proofreading the raw material on the top of the lower mold 1. During the continuous reciprocating motion of the two movable plates 27, the raw material will gradually align with the molding cavity at the top of the lower mold 1, which can effectively avoid the phenomenon of missing corners due to the misalignment of the raw material and the lower mold 1 during molding, thereby improving the molding effect of the mold.

[0035] See also Figure 1 - Figure 3An auxiliary mechanism 3 is symmetrically arranged on the top of the two movable plates 27. The auxiliary mechanism 3 includes a mounting plate 31 fixedly connected to the top of the movable plate 27, a plurality of spring rods 32 are fixedly connected to one side of the mounting plate 31, and a clamping pad 33 is fixedly connected to one end of the plurality of spring rods 32.

[0036] In this scheme, the length of the movable plate 27 and the clamping pad 33 is slightly smaller than the length of the lower mold 1, and both are parallel to the edge of the lower mold 1. When the movable plate 27 reciprocates, the mounting plate 31 will move with the movable plate 27, and then the clamping pad 33 will continuously contact the raw material above the lower mold 1. During the contact, due to the reaction force of the raw material on the clamping pad 33, the spring rod 32 will be pushed by the mounting plate 31 to shrink and generate elastic force, and then the spring rod 32 will release the elastic force, thereby pushing the raw material through the clamping pad 33. During the continuous reciprocating motion of the movable plate 27, the raw material is continuously pushed by the clamping pad 33, so that the position of the raw material is moved and gradually aligned with the molding cavity at the top of the lower mold 1. The auxiliary mechanism 3 is set to avoid rigid contact between the proofreading mechanism 2 and the raw material, thereby protecting the raw material. At the same time, with the spring rod 32 and the clamping pad 33, the position of the raw material can also be proofread more quickly.

[0037] Working principle: When in use, the raw material will fall into the top surface of the lower mold 1 through the external conveyor belt, and then the staff will start the switch of the cylinder 21, so that the cylinder 21 pushes the rack 22 to slide and drives the gear 23 and the cam 24 to rotate. The sliding limit plate 25 slides inside the lower mold 1 through the cam 24, and cooperates with the two rotating rods 26 to make the two movable plates 27 reciprocate on both sides of the lower mold 1. During the movement of the movable plate 27, the clamping pad 33 will continue to contact the raw material, and through the elastic force of the spring rod 32, the raw material will continue to move on the top surface of the lower mold 1, so that the raw material is gradually aligned with the molding cavity of the lower mold 1, thereby improving the molding effect of the mold.

[0038] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
