Description

Technical Field

[0001] This utility model relates to the technical field of machining mold guiding devices, specifically to a metal parts machining mold guiding device with a lubrication mechanism. Background Technology

[0002] Many automotive parts are manufactured using molds. For example, some metal parts are typically formed using stamping dies. These molds include upper and lower dies, and stamping is performed by the closing of the upper and lower dies. Accurate alignment is crucial when the upper and lower dies are closed to ensure the dimensional and shape accuracy of the automotive parts. To guarantee precise alignment, a guiding mechanism is usually installed. In ordinary machining molds, the upper die moves during closing, which may cause wobbling. Ordinary guiding mechanisms often fail to guarantee accurate and smooth guidance, and the lower die is generally not convenient for quick fixing and disassembly, thus affecting processing and usability.

[0003] A search revealed a utility model patent with publication number CN218925956U, which discloses a processing mold with a guiding function, including a support platform, a guiding moving device, and a fixing device. The guiding moving device includes a support leg, a fixing plate, a protective box, a motor, a screw, a top plate, a slide groove, a slider, a movable nut, a connecting rod, a rotating shaft, a movable plate, a guide rod, and a fixing sleeve. The bottom end of the support platform is fixedly connected to the support leg, the top end of the support platform is fixedly connected to the fixing plate, and the top end of the fixing plate is fixedly connected to the top plate. This application utilizes a motor to rotate the screw, which in turn rotates the screw threadedly with the movable nut. Under the action of the screw, the movable nut causes the slider to slide along the slide groove. The movable nut causes one end of the connecting rod to move, and the other end of the connecting rod pushes the movable plate downwards. The movable plate slides along the guide rod through the fixing sleeve, and the movable plate causes the upper mold plate to move downwards to the upper mold plate, thus facilitating smooth mold closing.

[0004] The aforementioned patent only involves starting a motor, which drives a screw to rotate. The screw and the movable nut rotate threadedly, and the movable nut, under the action of the screw, drives a slider to slide along a groove. The movable nut drives one end of a connecting rod to move, and the other end of the connecting rod pushes a movable plate down. The movable plate slides along a guide rod through a fixed sleeve, and the movable plate drives the upper mold plate down to the upper mold plate. This facilitates smooth mold closing, but it cannot adequately lubricate the guide screw and nut with timed and quantitative lubrication, making it difficult to ensure that the screw and nut can rotate for a long time. Damage may affect the production schedule.

[0005] Therefore, it is necessary to invent a metal parts processing mold guiding device with a lubrication mechanism to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a metal parts processing mold guiding device with a lubrication mechanism. A time-controlled switch controls an oil pump to add lubricating oil to the oil chamber at regular intervals and in a measured quantity. The lubricating oil is then added through oil inlet one and oil inlet two into the moving hole and sliding hole, respectively. As the moving block moves, the lubricating oil is evenly adhered to the surfaces of the bidirectional screw and guide slide, preventing damage to the moving block due to prolonged movement along the bidirectional screw and guide slide. This meets daily work needs, extends the service life of the bidirectional screw, guide slide, and moving block, and saves lubricating oil, avoiding waste. This solves the problem in existing technologies where the guide screw and nut cannot be adequately lubricated at regular intervals and in measured quantities, making it difficult to ensure the screw and nut can rotate for extended periods, which can damage and affect production progress.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a metal parts processing mold guiding device with a lubrication mechanism, comprising a support platform, movable blocks, and an oil tank. A fixed mold is fixedly installed on the top of the support platform, and a support frame is fixedly connected to the top of the support platform. A servo motor is installed inside the support frame, and the output shaft of the servo motor is fixedly connected to a bidirectional screw via a coupling. The bidirectional screw is rotatably connected to the support frame. A guide slide is fixedly connected inside the support frame, and movable blocks are symmetrically sleeved on the outside of the bidirectional screw and the guide slide. An oil tank is fixedly installed on the top of the support frame, and a time control switch is installed on the side of the oil tank. An oil pump is installed on the top of the oil tank, and the oil pump is fixedly connected to the two movable blocks via oil injection hoses. A movable hole and a sliding hole are opened inside the movable block. The movable hole is threadedly connected to the bidirectional screw, and the sliding hole is slidably connected to the guide slide. An oil cavity is opened inside the movable block, and an oil injection port two is fixedly connected between the oil cavity and the movable hole, and an oil injection port one is fixedly connected between the oil cavity and the sliding hole.

[0008] Preferably, the bottom of the movable block is hinged to a connecting rod, the ends of the two connecting rods are hinged to a lifting plate, and the bottom of the lifting plate is fixedly connected to a moving mold.

[0009] Preferably, guide rods are slidably provided on both sides of the lifting plate, and the guide rods are fixed between the support platform and the support frame.

[0010] Preferably, the support platform has symmetrically formed movable cavities inside, and an ejector block is slidably engaged between the movable cavity and the fixed mold.

[0011] Preferably, the bottom of the lifting plate is symmetrically fixed with operating rods, and the operating rods are fixedly connected to the top material block.

[0012] Preferably, a spring is fixedly connected between the operating lever and the movable cavity.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] 1. By controlling the oil pump to add lubricating oil to the oil chamber at regular intervals and in a measured amount through the time control switch, the lubricating oil will be added into the moving hole and sliding hole through oil injection port one and oil injection port two respectively. As the moving block moves, it will be evenly attached to the surface of the bidirectional screw and guide slide, preventing the moving block from being damaged due to long-term movement along the bidirectional screw and guide slide. This meets the needs of daily work, improves the service life of the bidirectional screw, guide slide and moving block, and saves lubricating oil, avoiding the waste of lubricating oil.

[0015] 2. During the mold closing process of the moving mold and the fixed mold, the operating lever is driven by the downward movement of the moving mold to move the ejector block into the movable cavity. At the same time, the spring is stretched, which will not affect the moving mold's stamping of the parts in the fixed mold. When the moving mold returns to its original position, the operating lever will pull the ejector block upward. With the spring's rebound and reset properties, the ejector block will push out the processed parts in the fixed mold, making it convenient for the staff to pick up the materials.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model provides, for example Figure 1-5 The device shown is a guide device for a metal parts processing mold with a lubrication mechanism, including a support platform 1, a movable block 7 and an oil tank 8. A fixed mold 2 is fixedly installed on the top of the support platform 1, and a support frame 3 is fixedly connected to the top of the support platform 1. A servo motor 4 is installed inside the support frame 3. The output shaft of the servo motor 4 is fixedly connected to a bidirectional screw 5 through a coupling. The bidirectional screw 5 is rotatably connected to the support frame 3. A guide slide rod 6 is fixedly connected inside the support frame 3. Movable blocks 7 are symmetrically sleeved on the outside of the bidirectional screw 5 and the guide slide rod 6. The servo motor 4 drives the bidirectional screw 5 to rotate. The movable block 7 slides along the guide slide rod 6 through the sliding hole 13, which can limit the movement of the movable block 7 back and forth in a straight line along the bidirectional screw 5.

[0026] An oil tank 8 is fixedly installed on the top of the support frame 3. A time control switch 9 is installed on the side of the oil tank 8. An oil pump 10 is installed on the top of the oil tank 8. The time control switch 9 is connected to the oil pump 10 through a control line. According to the actual working needs, lubricating oil is added to the bidirectional screw 5 and the guide slide rod 6 through the oil injection hose 11, oil chamber 14, oil injection port one 15 and oil injection port two 16 at regular intervals. This ensures that the moving block 7, bidirectional screw 5 and guide slide rod 6 will not wear out during long-term operation, and also saves lubricating oil and reduces production costs.

[0027] The oil pump 10 is fixedly connected to the two movable blocks 7 via an oil injection hose 11. The movable block 7 has a movable hole 12 and a sliding hole 13 inside. The movable hole 12 is threadedly connected to the bidirectional screw 5, and the sliding hole 13 is slidably connected to the guide slide rod 6. The movable block 7 has an oil cavity 14 inside. The oil cavity 14 is fixedly connected to the movable hole 12 via an oil injection port 2 16, and the oil cavity 14 is fixedly connected to the sliding hole 13 via an oil injection port 15.

[0028] The bottom of the movable block 7 is hinged with a connecting rod 17, and the ends of the two connecting rods 17 are hinged with lifting plates 18. The bottom of the lifting plate 18 is fixedly connected with a moving mold 19. When the movable block 7 moves, it will push the moving mold 19 up and down to move closer to the fixed mold 2 through the connecting rods 17.

[0029] Guide rods 20 are slidably installed on both sides of the lifting plate 18. The guide rods 20 are fixed between the support platform 1 and the support frame 3. When the moving mold 19 moves up and down, the lifting plate 18 will slide along the guide rods 20, which plays an auxiliary role in guiding the sliding.

[0030] The support platform 1 has symmetrically opened movable cavities 21. An ejector block 22 is slidably locked between the movable cavity 21 and the fixed mold 2. When the moving mold 19 moves up and down, the ejector block 22 can be pressed down by the operating rod 23 and stored inside the movable cavity 21 to avoid affecting the closing of the moving mold 19 and the fixed mold 2 for stamping.

[0031] The bottom of the lifting plate 18 is symmetrically fixed with operating rods 23. The operating rods 23 are fixedly connected to the top material block 22. As the moving mold 19 returns to its position, it will pull the operating rods 23 and the top material block 22 upward, which will help push the processed parts to separate from the fixed mold 2, making it easier to remove the material.

[0032] A spring 24 is fixedly connected between the operating lever 23 and the movable cavity 21. The elasticity of the spring 24 can help the ejector block 22 return to its original position and eject the processed parts from the fixed mold 2.

[0033] The working principle of this practical application is as follows:

[0034] All electrical components in this device are connected to external control switches and power supplies. By starting the servo motor 4, the servo motor 4 drives the bidirectional screw 5 to rotate. The moving block 7 moves linearly along the bidirectional screw 5 under the limiting action of sliding along the guide slide rod 6. The moving block 7 drives one end of the connecting rod 17 to move, and the other end of the connecting rod 17 pushes the lifting plate 18 to move down. The two sides of the lifting plate 18 will slide along the guide rod 20 to realize the up and down movement of the auxiliary moving mold 19, so as to facilitate smooth mold closing with the fixed mold 2. When the moving mold 19 moves down close to the fixed mold 2, the ejector block 22 will be pushed into the movable cavity 21 by the operating rod 23. The top surface of the ejector block 22 is joined with the bottom of the fixed mold 2, which does not affect the stamping of parts. When the moving mold 19 returns to its position, the operating rod 23, in conjunction with the elasticity of the spring 24, drives the ejector block 22 to push upward during the upward movement, ejecting the parts processed in the fixed mold 2 for easy material removal.

[0035] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
