Description

Technical Field

[0001] This utility model relates to the field of demolding mechanism technology, specifically a demolding mechanism for stamping dies that can be automatically lubricated. Background Technology

[0002] Stamping dies are special process equipment used in cold stamping to process metal or non-metal materials into parts (or semi-finished products). They are commonly known as cold stamping dies. Stamping is a pressure processing method that uses dies mounted on a press to apply pressure to materials at room temperature, causing them to separate or undergo plastic deformation, thereby obtaining the desired parts. The demolding mechanism of a stamping die is a mechanism that allows the stamped workpiece to be removed from the die for easy handling by workers.

[0003] Chinese Utility Model Announcement No. CN213793772U includes a device body and a stamping mechanism. The stamping mechanism is located at the top of the device body. The device body includes a mold body with a mold groove at its top. A demolding mechanism is located inside the mold body, including a lead screw. The lead screw is movably mounted inside the mold body via bearings, and a first bevel gear is fixedly mounted at the bottom of the lead screw. This utility model, by incorporating a demolding mechanism, allows the operator to rotate a handle, causing the lead screw to rotate and the lead screw nut to move upwards, thus ejecting the mold from the ejector plate. This enables the operator to quickly eject the mold, achieving rapid demolding, increasing the practicality of the structure, and improving the work efficiency of the operator.

[0004] The applicant discovered some shortcomings in the use of the patent: the lead screw and bevel gear do not have the function of automatically spraying lubricating oil, and each spraying still needs to be done manually by the staff, which is not convenient enough.

[0005] Therefore, this utility model designs a stamping die demolding mechanism with automatic lubrication to solve the problems existing in the prior art. Utility Model Content

[0006] The purpose of this invention is to provide a stamping die demolding mechanism that can perform automatic lubrication, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a stamping die ejection mechanism capable of automatic lubrication, comprising: a base box, a lower die mounted on the top of the base box, a top plate slidably mounted inside the lower die, an ejection assembly provided inside the base box, a U-shaped frame mounted in the middle of one inner wall of the base box, a rotating shaft rotatably mounted between the two ends of the U-shaped frame, a rotating block mounted in the middle of the outer wall of the rotating shaft, one end of the rotating shaft connected to the output end of a servo motor, a connecting pipe mounted on one side of the rotating block, a nozzle provided on one side of the connecting pipe, an oil storage tank mounted at one end of the bottom inner wall of the base box, an oil pump provided below the oil storage tank, the oil pump and the connecting pipe connected through an oil pipe, the servo motor driving the rotating shaft to rotate forward and backward, which can cause the rotating block to drive the nozzle to swing up and down, so that the nozzle can spray lubricating oil onto different positions of the lead screw.

[0008] Preferably, the ejection assembly includes a lead screw, which is rotatably mounted in the middle of the bottom inner wall of the base box. A sleeve is slidably mounted on the upper side of the outer wall of the lead screw via a thread. The top of the sleeve passes through the base box and the lower mold and connects to the middle of the bottom of the top plate. A driven gear is mounted on the lower side of the outer wall of the lead screw. A long rod is rotatably mounted on the side of the base box away from the U-shaped frame. A driving gear that meshes with the driven gear is mounted on one side of the long rod. Rotating the long rod causes the lead screw to rotate through the meshing of the driving gear and the driven gear, which in turn causes the sleeve to rise. The sleeve then causes the top plate to rise, ejecting the workpiece. Since the top plate and the lower mold are slidably mounted, the top plate slides within the lower mold, thus limiting the movement of the lead screw and the sleeve.

[0009] Preferably, a handwheel is installed on the side of the long rod away from the drive gear, which allows the operator to easily rotate the long rod.

[0010] Preferably, a sloping groove is provided at the middle of the bottom of the base box, and a slot communicating with the sloping groove is provided at one end of the base box. A collection box flush with the sloping groove is inserted into the slot. Excess lubricating oil flows down the lead screw into the sloping groove and then flows to the collection box for collection, thus avoiding the waste of lubricating oil.

[0011] Preferably, a magnetic strip is installed at one end of both the collection box and the slot, which can improve the stability of the collection box in the slot.

[0012] Preferably, the other end of the collection box has two grooves, and the operator can insert two fingers into the two grooves to pinch the collection box, making it easy to pull the collection box out of the slot.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model allows the lubricating oil in the oil tank to enter the connecting pipe through the oil pipe by starting the oil pump, and then be sprayed out through the nozzle. By rotating the shaft in both directions, the rotating block swings up and down, causing the nozzle to tilt up and down, thus spraying lubricating oil on different positions of the lead screw and the driven gear. This eliminates the need for manual spraying by staff and is more convenient. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 This utility model provides an embodiment of a stamping die demolding mechanism capable of automatic lubrication, comprising: a base box 1, a lower die 2 mounted on the top of the base box 1, a top plate 3 slidably mounted inside the lower die 2, an ejection assembly 4 inside the base box 1, a U-shaped frame 5 mounted in the middle of one side inner wall of the base box 1, a rotating shaft 6 rotatably mounted between the two ends of the U-shaped frame 5, a rotating block 7 mounted in the middle of the outer side wall of the rotating shaft 6, one end of the rotating shaft 6 connected to the output end of a servo motor, a connecting pipe 8 mounted on one side of the rotating block 7, a nozzle 9 mounted on one side of the connecting pipe 8, an oil storage tank 10 mounted on one end of the bottom inner wall of the base box 1, an oil pump 11 mounted below the oil storage tank 10, the oil pump 11 and the connecting pipe 8 connected through an oil pipe 12, an addition port above the oil storage tank 10 for easy addition of lubricating oil, and a transparent observation frame at one end for easy observation of the oil level by the operator.

[0021] Please see Figure 1-3In this embodiment: the ejection assembly 4 includes a lead screw 401, which is rotatably installed in the middle of the bottom inner wall of the bottom box 1. A sleeve 402 is slidably installed on the upper side of the outer wall of the lead screw 401 by means of threads. The top of the sleeve 402 passes through the bottom box 1 and the lower mold 2 and is connected to the middle of the bottom of the top plate 3. A driven gear 403 is installed below the outer wall of the lead screw 401. A long rod 404 is rotatably installed on the side of the bottom box 1 away from the U-shaped frame 5. A driving gear 405 that meshes with the driven gear 403 is installed on one side of the long rod 404.

[0022] Please see Figure 1-3 In this embodiment: a handwheel is installed on the side of the long rod 404 away from the drive gear 405.

[0023] Please see Figure 1-3 In this embodiment: a sloping groove 13 is provided at the middle of the bottom of the bottom box 1, and a slot 14 communicating with the sloping groove 13 is provided at one end of the bottom box 1. A collection box 15 that is flush with the sloping groove 13 is inserted into the slot 14.

[0024] Please see Figure 1-3 In this embodiment: magnetic strips are installed at one end of the collection box 15 and the slot 14. The two magnetic strips are positive and negative and attract each other.

[0025] Please see Figure 1-3 In this embodiment: two grooves are provided at the other end of the collection box 15, and sponges are provided in the grooves to improve comfort.

[0026] Working principle: After stamping, rotating the long rod 404 causes the driving gear 405 to drive the driven gear 403 to rotate, causing the lead screw 401 to rotate. This causes the sleeve 402 to rise, which in turn raises the top plate 3, pushing the stamped workpiece upwards out of the lower die 2 for easy handling by the operator. The oil pump 11 is started, and the lubricating oil in the oil tank 10 is transported through the oil pipe 12 to the connecting pipe 8 and then sprayed out through the nozzle 9. The rotating block 7 is driven to rotate forward and backward through the rotating shaft 6. By adjusting the angle of the nozzle 9, the nozzle 9 can spray lubricating oil onto different positions of the lead screw 401 and the driven gear 403. Since the driving gear 405 and the driven gear 403 are meshed, the driving gear 405 can also be coated with lubricating oil from the driven gear 403. After lubrication, the operator can rotate more easily. The contents not described in detail in this description are existing technologies known to those skilled in the art.
