[0005] To achieve the above purpose, the utility model adopts the following technical scheme: a manufacturing die for a rear end cover, including a bottom plate, a support rod is fixedly connected to the surface of the bottom plate, and a top plate is fixed at one end of the support rod. A hydraulic rod is fixedly penetrated through the top plate. A moving die is fixed at one end of the hydraulic rod. A fixed die is fixed on one side of the bottom plate. An empty groove is opened in the fixed die. A pushing plate is embedded in the fixed die. A lead screw and a worm are rotated in the empty groove of the fixed die. A worm gear is fixed at one end of the lead screw. The worm gear is meshed with the worm. A connecting piece is threadedly connected to the lead screw. A vertical rod is fixed at one end of the connecting piece. The vertical rod penetrates through the fixed die and is fixedly connected to the pushing plate. A main shaft is fixed at one end of the worm. The main shaft penetrates through the fixed die. A motor is fixed at one end of the main shaft. The motor is fixedly connected to the bottom plate.

[0006] As a preferred embodiment, a guide rod is fixedly connected to one side surface of the top plate. The guide rod penetrates through the moving die and is fixedly connected to the fixed die.

[0007] As a preferred embodiment, the number of the connecting pieces, the lead screws and the worm gears is multiple.

[0008] As a preferred embodiment, a protective cover is fixedly connected to the surface of the bottom plate near the position where the motor is located. The protective cover penetrates through between the main shaft.

[0009] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0010] In the present utility model, the main shaft and the worm are driven to rotate by a motor, and then the rotation of the worm wheel and the lead screw is driven, so that the connecting piece drives the vertical rod to gradually move upward, thereby enabling the pushing plate to push the rear end cover formed in the fixed mold upward and eject the rear end cover from the fixed mold, which is convenient for the staff to take and effectively improves the overall work efficiency.

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to 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 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.

[0017] Embodiment 1

[0018] As Figures 1-3As shown in the figure, the utility model provides a technical solution: a manufacturing die for a rear end cover, which includes a bottom plate 1. A support rod 2 is fixedly connected to the surface of the bottom plate 1, and a top plate 3 is fixed to one end of the support rod 2. A hydraulic rod 4 is fixedly penetrated through the top plate 3. One end of the hydraulic rod 4 is fixed with a movable die 5. The setting of the hydraulic rod 4 facilitates the control of the up and down movement of the movable die 5. When the rear end cover is die-cast, the hydraulic rod 4 is contracted to move the movable die 5 upward, which is convenient for the subsequent taking work of the rear end cover. One side of the bottom plate 1 is fixed with a fixed die 6. An empty groove is opened in the fixed die 6. A push plate 8 is embedded in the fixed die 6. A lead screw 11 and a worm 13 are rotated in the empty groove of the fixed die 6. One end of the lead screw 11 is fixed with a worm gear 12, and the worm gear 12 is meshed with the worm 13. When the worm 13 rotates, with the cooperation of the worm gear 12, it is convenient for the lead screw 11 to rotate together. A connecting piece 10 is threadedly connected to the lead screw 11, and one end of the connecting piece 10 is fixed with a vertical rod 9. The vertical rod 9 penetrates through the fixed die 6 and is fixedly connected to the push plate 8. When the lead screw 11 rotates, the connecting piece 10 will carry the vertical rod 9 to gradually move upward, so that the push plate 8 pushes the rear end cover formed in the fixed die 6 upward, and the rear end cover is ejected from the fixed die 6, which is convenient for the staff to take. One end of the worm 13 is fixed with a main shaft 14, and the main shaft 14 penetrates through the fixed die 6. One end of the main shaft 14 is fixed with a motor 15, and the motor 15 is fixedly connected to the bottom plate 1. The driving of the motor 15 facilitates the driving of the main shaft 14 and the worm 13 to rotate together.

[0019] Embodiment 2

[0020] As Figures 1-3 shown, a guide rod 7 is fixedly connected to one side surface of the top plate 3. The guide rod 7 penetrates through the movable die 5 and is fixedly connected to the fixed die 6. The setting of the guide rod 7 plays a guiding role in the movement of the movable die 5 and improves the stability of the up and down linear movement of the movable die 5. The number of the connecting piece 10, the lead screw 11 and the worm gear 12 is set to be multiple, so that the push plate 8 can push upward more stably and powerfully, and the rear end cover is easier to be ejected. A protective cover 16 is fixedly connected to the surface of the bottom plate 1 near the position where the motor 15 is located, and the protective cover 16 penetrates through the main shaft 14. The protective cover 16 plays a role in protecting the motor 15 and effectively avoids the damage of the motor 15 due to the influence of the outside world.

[0021] Working principle:

[0022] As Figures 1-3As shown in the figure, when in use, when the rear end cover needs to be taken out during die-casting in the moving die 5 and the fixed die 6, the user first controls the hydraulic rod 4 on the top plate 3 to contract, so that the moving die 5 moves steadily upward along the guide rod 7, separating the moving die 5 from the fixed die 6. Then, the motor 15 in the protective cover 16 is started to drive the main shaft 14 and the worm 13 to rotate. The rotation of the worm 13 drives the worm wheel 12 to rotate, and further drives the rotation of the lead screw 11. The rotation of the lead screw 11 drives the connecting member 10 and the vertical rod 9 to move upward in a straight line, so that the pushing plate 8 pushes the rear end cover formed in the fixed die 6 upward. Finally, the rear end cover will be pushed out of the fixed die 6, which is convenient for the staff to take.

[0023] The above is only the preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
