Description

Technical Field

[0001] This utility model belongs to the field of stamping die technology, specifically relating to a stamping die for an electric motor fuel injection pipe. Background Technology

[0002] An electric motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. An oil spray pipe is installed inside the motor. The oil spray pipe is mainly used to spray cooling oil or lubricating oil into the motor (such as stator windings, bearings, gear pairs, etc.) to reduce operating temperature, reduce wear, extend motor life and improve efficiency. Its design ensures that the oil accurately covers key components.

[0003] Currently, factories typically use stamping to produce fuel injection pipes, thus requiring stamping dies. However, existing stamping dies often require cumbersome unloading operations, making them inconvenient to use. They also require multiple drive sources, increasing maintenance costs and complicating the control system, hindering practical application. Therefore, there is an urgent need for a new type of stamping die for motor-driven fuel injection pipes.

[0004] A patent with publication number CN222175901 U provides a die-casting mold for easy unloading. It includes a hydraulic press, a stamping die, grooves, slots, a stamping groove, a hydraulic cylinder, and a moving plate. When demolding is required, the hydraulic press is activated to raise the stamping die. Simultaneously, workers pour a lubricating release agent through the grooves and slots into the stamping groove to facilitate demolding of the die-cast part. Subsequently, the hydraulic cylinder is activated, and its telescopic shaft raises the moving plate to achieve unloading.

[0005] However, the above-mentioned solution requires not only a hydraulic press to lift the stamping die but also a hydraulic cylinder to lift the moving plate to complete the demolding operation. This necessitates the use of multiple drive sources, increasing the complexity of the control system design. Furthermore, the solution requires manual application of lubricating release agent, making the operation cumbersome, inconvenient, and unsuitable for practical application. Utility Model Content

[0006] To address the problems existing in the background technology, this utility model provides a stamping die for an electric motor fuel injection pipe.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A stamping die for an electric motor fuel injection pipe includes a base on which a lower die is mounted and a mounting plate connected to an external hydraulic device. An upper die is fixedly mounted on the bottom of the mounting plate. A rotating shaft is rotatably mounted horizontally inside the base, and a one-way bearing is fitted on the outer surface of the rotating shaft. The mounting plate acts on the one-way bearing through a first transmission component. A sliding rod is limited and slidable vertically inside the base. A top rod located inside the lower die is fixedly mounted on the top of the sliding rod, and the rotating shaft acts on the sliding rod through a second transmission component. A storage box communicating with the lower die is fixedly mounted on the top of the base, and a nozzle is mounted on the lower die. A sealing plate is slidably mounted in the storage box, and the sliding rod acts on the sealing plate through an elastic auxiliary component.

[0009] Furthermore, the top of the push rod is flush with and adapted to the bottom of the mold cavity of the lower mold.

[0010] Furthermore, the first transmission component includes a guide rod, a guide rod fixedly mounted on the top of the base, a baffle slidably mounted inside the guide rod along the vertical direction, a mounting plate slidably sleeved on the outer surface of the guide rod, and the baffle located above the mounting plate; a connecting rod fixedly mounted on the bottom of the baffle, a first rack fixedly mounted on the bottom of the connecting rod, and a third spring provided between the first rack and the base; a first gear fixedly mounted on the outer surface of the one-way bearing, and the first gear meshes with the first rack for transmission.

[0011] Furthermore, the second transmission component includes a second gear, which is fixedly sleeved on the outer surface of the rotating shaft. The second gear is an incomplete gear. A second rack is fixedly installed at the bottom of the sliding rod. The second rack is connected to the base by a first spring and also engages with the second gear in a contact-type transmission.

[0012] Furthermore, a first oil supply pipe and a second oil supply pipe are fixedly connected to the storage tank. The storage tank is connected to the interior of the lower mold through the first oil supply pipe and to an external oil tank through the second oil supply pipe. A one-way valve is installed in both the first and second oil supply pipes.

[0013] Furthermore, the sealing plate divides the storage tank into an oil-filled chamber and an oil-free chamber.

[0014] Furthermore, an air pipe connected to the oil-free chamber is fixedly installed on the storage box.

[0015] Furthermore, the elastic auxiliary component includes an inclined block, and the inclined block is fixedly installed on the top of the sliding rod; the sealing plate is fixedly installed on the side facing the oil-free cavity, one end of the sliding rod extends slidably to the outside of the storage box and is fixedly installed on a slider, the bottom of the slider is inclined and engages with the inclined block in a transmission manner; a second spring is sleeved on the outer surface of the sliding rod, one end of the second spring is fixedly connected to the storage box, and the other end is fixedly connected to the slider.

[0016] This application has the following beneficial effects:

[0017] 1. During the process of the external hydraulic device driving the mounting plate and the upper mold to rise, the mounting plate drives the one-way bearing and the rotating shaft to rotate through the first transmission component. The rotating shaft drives the sliding rod and the ejector rod to rise through the second transmission component, so as to lift the motor oil injection pipe and thus demold the motor oil injection pipe. The whole process does not require the use of an external drive source, thereby reducing maintenance costs and reducing the construction difficulty of the control system, which is more conducive to practical promotion and use.

[0018] 2. After the motor oil injection pipe is lifted by the push rod, as the sliding rod continues to rise, the sliding rod acts on the sealing plate through the elastic auxiliary component, causing the sealing plate to slide within the storage tank. This forces the lubricating oil in the storage tank into the lower mold and sprays it through the nozzle into the mold cavity of the lower mold, providing pre-lubrication for the next stamping and facilitating subsequent demolding. The entire process is simpler to operate and more convenient to use, further improving the practical effect of this application. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0028] like Figures 1-5 As shown, the technical solution adopted by this utility model is as follows: A stamping die for an electric motor fuel injection pipe includes a base 1 on which a lower die 4 is mounted and a mounting plate 2 connected to an external hydraulic device. An upper die 3 corresponding to the lower die 4 is fixedly mounted on the bottom of the mounting plate 2. (It should be noted that the external hydraulic device in this application is conventional prior art and will not be described in detail here.)

[0029] A rotating shaft 9 is rotatably mounted in the base 1 along the horizontal direction. A one-way bearing 10 is fixedly sleeved on the outer surface of the rotating shaft 9. The mounting plate 2 acts on the one-way bearing 10 through the first transmission component. A sliding rod 15 is slidably mounted in the base 1 along the vertical direction. A top rod 16 is fixedly mounted on the top of the sliding rod 15. The rotating shaft 9 acts on the top rod 16 through the second transmission component.

[0030] Furthermore, the top of the ejector pin 16 is flush with and fits the bottom of the mold cavity of the lower mold 4.

[0031] The first transmission component includes a guide rod 5. The guide rod 5 is fixedly installed on the top of the base 1. A baffle 6 is slidably installed inside the guide rod 5 along the vertical direction. The mounting plate 2 is slidably sleeved on the outer surface of the guide rod 5. The baffle 6 is located above the mounting plate 2.

[0032] A connecting rod 7 is fixedly installed at the bottom of the baffle 6, and a first rack 8 is fixedly installed at the bottom of the connecting rod 7. A third spring 23 is provided between the first rack 8 and the base 1. A first gear 11 is fixedly sleeved on the outer surface of the one-way bearing 10, and the first gear 11 meshes with the first rack 8 for transmission.

[0033] The second transmission component includes a second gear 12, which is fixedly sleeved on the outer surface of the rotating shaft 9. The second gear 12 is an incomplete gear. A second rack 13 is fixedly installed at the bottom of the sliding rod 15. The second rack 13 is connected to the base 1 by a first spring 14 and also engages with the second gear 12 in a contact-type transmission.

[0034] A storage box 17 is fixedly installed on the top of the base 1. The storage box 17 contains lubricating oil and is also sealed and slidably equipped with a sealing plate 19. The sliding rod 15 acts on the sealing plate 19 through an elastic auxiliary component.

[0035] Furthermore, a first oil supply pipe 21 and a second oil supply pipe 24 are fixedly connected to the storage tank 17. The storage tank 17 is connected to the interior of the lower mold 4 through the first oil supply pipe 21 and to the external oil tank through the second oil supply pipe 24. A one-way valve is installed in both the first oil supply pipe 21 and the second oil supply pipe 24.

[0036] Furthermore, an oil outlet hole is opened on the lower mold 4, and a nozzle 22 is installed at the oil outlet hole.

[0037] Furthermore, the sealing plate 19 divides the storage box 17 into an oil-containing chamber and an oil-free chamber, and an air pipe connected to the oil-free chamber is fixedly installed on the storage box 17.

[0038] The elastic auxiliary component includes a ramp block 25, which is fixedly mounted on the top of the sliding rod 15. A sliding rod 26 is fixedly mounted on the side of the sealing plate 19 facing the oil-free cavity. One end of the sliding rod 26 extends slidably to the outside of the storage box 17 and is fixedly mounted on a slider 18. The bottom of the slider 18 is inclined and engages with the ramp block 25. A second spring 20 is fitted onto the outer surface of the sliding rod 26. One end of the second spring 20 is fixedly connected to the storage box 17, and the other end is fixedly connected to the slider 18.

[0039] Working principle: In the initial state, the baffle 6 abuts against the mounting plate 2, and the third spring 23 is in a stretched state.

[0040] In use, the workpiece to be stamped is placed in the cavity of the lower mold 4. An external hydraulic device lowers the mounting plate 2 and the lower mold 4. At the beginning of this process, the third spring 23 pulls the first rack 8, connecting rod 7, and baffle 6 downwards simultaneously, causing the first gear 11 to rotate the one-way bearing 10 until the third spring 23 returns to its original shape. However, at this time, the one-way bearing 10 is in an idle state, and the rotating shaft 9 does not rotate.

[0041] After the third spring 23 recovers its deformation, as the mounting plate 2 continues to descend, the mounting plate 2 will disengage from the baffle 6, and the upper mold 3 will perform a stamping operation on the workpiece.

[0042] After stamping is completed, the mounting plate 2 and the upper mold 3 are lifted by an external hydraulic device. During this process, the upper mold 3 will contact the baffle 6 and lift the baffle 6, so that the third spring 23 is gradually stretched.

[0043] At this time, the one-way bearing 10 is locked, causing the rotating shaft 9 to rotate. The rotating shaft 9 drives the second gear 12 to rotate synchronously. During the rotation of the second gear 12, it will contact and mesh with the second rack 13, causing the second rack 13 to push the sliding rod 15 up and stretch the first spring 14.

[0044] Furthermore, as the sliding rod 15 rises, it drives the push rod 16 and the inclined block 25 to rise synchronously, thereby lifting the stamped workpiece. As the sliding rod 15 continues to rise, the inclined surface of the inclined block 25 will contact the bottom inclined surface of the slider 18, causing the slider 18 to push the sealing plate 19 to slide in the storage box 17 through the sliding rod 26 and compress the second spring 20. Thus, under the restriction of the one-way valve, the lubricating oil in the storage box 17 is transported to the lower mold 4 through the first oil supply pipe 21, and sprayed into the mold cavity of the lower mold 4 through the nozzle 22 installed in the lower mold 4, so as to lubricate in advance for the next stamping and facilitate subsequent demolding.

[0045] Subsequently, the workpiece after being lifted and stamped is removed, and the rotating shaft 9 continues to rotate until the second gear 12 disengages from the second rack 13. After disengagement, the second rack 13 pulls the sliding rod 15 down to reset under the elastic assistance of the first spring 14, and also resets the push rod 16. At the same time, during the descent and reset of the sliding rod 15, the inclined block 25 disengages from the slider 18, causing the slider 18 to pull the sealing plate 19 back to reset under the elastic action of the second spring 20. Thus, under the restriction of the one-way valve, the lubricating oil in the oil tank is drawn into the storage tank 17, thereby replenishing the lubricating oil in the storage tank 17 for subsequent oil spraying operations.

[0046] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
