Description

Technical Field

[0001] This utility model relates to the field of lubrication of die-casting punches in die-casting machines, specifically a lubrication mechanism for die-casting punches in die-casting machines. Background Technology

[0002] A die casting machine is a machine used for pressure casting. It uses pressure to inject molten metal into a mold, and after cooling and solidification, a solid metal casting is obtained. A die casting machine mainly consists of a mold clamping mechanism, an injection mechanism, a hydraulic system, and an electrical control system. A die casting punch is a punch used in a die casting mold. It is usually made of steel and has a fine structure and a compact shape. Its main function is to break through the plugs (such as steel fibers, sand particles, etc.) in the die casting mold under high temperature and high pressure conditions and remove them before the molten metal is punched out, so as to ensure the quality of the product.

[0003] During the die casting process, the mold and punch are constantly subjected to high-intensity mechanical pressure and friction, which leads to wear and corrosion of the mold and punch. In order to reduce this wear and corrosion, a lubrication mechanism for the die casting punch needs to be installed on the die casting machine to supply lubrication as needed, thereby improving production efficiency and product quality. The installation position of the lubrication mechanism for the die casting punch in a common die casting machine is determined according to the model of the die casting machine and the lubrication requirements. The lubrication mechanism for the die casting punch is then fixed to the outer wall of the die casting machine with screws.

[0004] However, when the lubrication mechanism of the die-casting punch of the aforementioned die-casting machine is installed on different models and specifications of die-casting machines, the position needs to be repeatedly adjusted to adapt to the lubrication requirements in actual production. The positioning process is often cumbersome and time-consuming, affecting the production progress. Therefore, it is necessary to modify the existing lubrication mechanism of the die-casting punch of the die-casting machine. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a lubrication mechanism for the die-casting punch of a die-casting machine, so as to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lubrication mechanism for a die-casting punch of a die-casting machine, comprising a mechanism fixing frame and a lubrication mechanism body. A lead screw is rotatably mounted on the inner wall of the mechanism fixing frame, and a rotating hole for rotation is opened at the end of the lead screw. A moving block is threadedly mounted on the outer wall of the lead screw, and a rotating block is mounted on the outer wall of the moving block. A first fixed tooth is mounted on the outer wall of the rotating block, and a corresponding second fixed tooth is mounted on the outer wall of the moving block. A spring is mounted on the outer wall of the moving block, and the lubrication mechanism body is mounted on the outer wall of the rotating block.

[0007] By adopting the above technical solution, the accuracy and stability of the height adjustment of the main body 12 of the lubrication mechanism are ensured, the convenience and reliability of the entire installation process are ensured, and the installation efficiency of the lubrication mechanism of the die-casting punch of the die-casting machine is improved.

[0008] Furthermore, the movable block has a rectangular design, and the outer wall of the movable block is in close contact with the inner wall of the mechanism fixing frame.

[0009] By adopting the above technical solution, it is ensured that the moving block moves only vertically and will not rotate with the lead screw, thus avoiding unnecessary rotation or offset, thereby ensuring the accuracy and stability of the height adjustment of the main body of the lubrication mechanism.

[0010] Furthermore, the rotating block is designed with an arc shape near the outer wall of the mechanism fixing frame, and the rotating block is sleeved on the outer wall of the lead screw.

[0011] By adopting the above technical solution, it is beneficial for the rotating block to rotate around the lead screw, and it will not collide with the outer wall of the mechanism's fixed frame.

[0012] Furthermore, the width of the rotating block is smaller than that of the moving block, and the length of the rotating block is greater than that of the moving block.

[0013] By adopting the above technical solution, the rotating block can drive the main body of the lubrication mechanism to move along with the moving block without affecting the rotation of the rotating block.

[0014] Furthermore, the outer wall of the movable block is equipped with multiple sets of first fixed teeth at equal intervals, and the outer wall of the rotating block is equipped with multiple sets of second fixed teeth at equal intervals.

[0015] By adopting the above technical solution, it is beneficial to limit the position of the rotating block through the close cooperation of the first fixed tooth and the second fixed tooth, which helps to ensure the stability of the mechanism operation.

[0016] Furthermore, the spring is fixedly connected to the moving block, and the spring is rotatably connected to the rotating block.

[0017] By adopting the above technical solution, the spring will not affect the rotation of the rotating block, and can pull the rotating block to complete the reset.

[0018] Furthermore, the outer wall of the mechanism fixing frame near the main body of the lubrication mechanism has an arc-shaped opening design, and the outer wall of the mechanism fixing frame is provided with fixing holes for connecting screws.

[0019] By adopting the above technical solution, it is beneficial that the moving block drives the main body of the lubrication mechanism to rotate without restriction, and the mechanism fixing frame can be firmly fixed on the die-casting machine by screws.

[0020] In summary, the present invention has the following main advantages:

[0021] This invention, by incorporating a lead screw and a movable block, allows the lubrication mechanism of the die-casting punch to move smoothly vertically after the fixed mechanism frame is installed. This facilitates fine-tuning based on site conditions during installation to achieve optimal lubrication and installation position. The invention also includes a rotating block, a first fixed tooth, a second fixed tooth, and a spring. After the height of the lubrication mechanism is adjusted, lifting the rotating block releases the first and second fixed teeth, allowing them to rotate freely and adjust the angle. This ensures accurate lubrication of all critical lubrication areas of the die-casting punch. The spring then repositions the rotating block and the first fixed tooth, re-engaging them to form a secure locking structure, thus fixing the lubrication mechanism. This ensures convenient and reliable installation and improves the efficiency of the die-casting punch lubrication mechanism installation. Attached Figure Description

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0028] The embodiments of this utility model will be described below based on its overall structure.

[0029] A lubrication mechanism for a die-casting punch in a die-casting machine, such as Figure 1 - Figure 4As shown, the mechanism includes a fixing frame 1 and a lubrication mechanism body 12. A lead screw 2 is rotatably mounted on the inner wall of the fixing frame 1, and a rotating hole 21 is provided at the end of the lead screw 2 for rotation. The lead screw 2 can be rotated by using an Allen wrench through the rotating hole 21. A moving block 31 is threadedly mounted on the outer wall of the lead screw 2. The moving block 31 moves vertically by rotating the lead screw 2, thereby adjusting the height of the lubrication mechanism body 12. A rotating block 3 is mounted on the outer wall of the moving block 31. A first fixed tooth 32 is mounted on the outer wall of the rotating block 3, and a corresponding second fixed tooth 33 is mounted on the outer wall of the moving block 31. The position of the rotating block 3 is limited by the tight cooperation of the first fixed tooth 32 and the second fixed tooth 33, which helps to ensure the stability of the mechanism operation. A spring 4 is mounted on the outer wall of the moving block 31, which can pull the rotating block 3 to complete the reset. The lubrication mechanism body 12 is mounted on the outer wall of the rotating block 3.

[0030] Please see Figure 1 - Figure 4 The movable block 31 has a rectangular design, and its outer wall is in close contact with the inner wall of the mechanism fixing frame 1, which ensures that the movable block 31 moves only vertically and will not rotate with the lead screw 2, thus avoiding unnecessary rotation or offset, thereby ensuring the accuracy and stability of the height adjustment of the lubrication mechanism body 12.

[0031] Please see Figure 1 - Figure 4 The rotating block 3 is designed with an arc shape near the outer wall of the mechanism fixing frame 1, and the rotating block 3 is sleeved on the outer wall of the lead screw 2, which is conducive to the rotating block 3 rotating around the lead screw 2 and will not collide with the outer wall of the mechanism fixing frame 1.

[0032] Please see Figure 1 - Figure 4 The width of the rotating block 3 is smaller than that of the moving block 31, and the length of the rotating block 3 is greater than that of the moving block 31, so that the rotating block 3 can drive the lubrication mechanism body 12 to move with the moving block 31 without affecting the rotation of the rotating block 3.

[0033] Please see Figure 4 Multiple sets of first fixed teeth 32 are installed at equal intervals on the outer wall of the moving block 31, and multiple sets of second fixed teeth 33 are installed at equal intervals on the outer wall of the rotating block 3. This helps to limit the position of the rotating block 3 through the close cooperation of the first fixed teeth 32 and the second fixed teeth 33, which helps to ensure the stability of the mechanism operation.

[0034] Please see Figure 4 Spring 4 is fixedly connected to moving block 31, and spring 4 is rotatably connected to rotating block 3, so that spring 4 will not affect the rotation of rotating block 3, and can pull rotating block 3 to complete the reset.

[0035] Please see Figure 1 - Figure 4The mechanism fixing frame 1 has an arc-shaped opening on the outer wall near the lubrication mechanism body 12, and the outer wall of the mechanism fixing frame 1 has fixing holes 11 for connecting screws. This allows the moving block 3 to rotate the lubrication mechanism body 12 without restriction, and the mechanism fixing frame 1 can be firmly fixed on the die casting machine by screws.

[0036] The working principle of this utility model is as follows: When it is necessary to install the lubrication mechanism of the die-casting punch of the die-casting machine, the initial positioning and installation of the mechanism fixing frame 1 is first completed by using screws through the fixing hole 11, laying a solid foundation for the smooth progress of subsequent steps. Then, the Allen wrench is used to drive the lead screw 2 to rotate through the rotating hole 21, so that the moving block 31 moves vertically, completing the height adjustment of the lubrication mechanism body 12. The rectangular design of the moving block 31 ensures that the moving block 31 only moves vertically and will not rotate with the lead screw 2, avoiding unnecessary rotation or offset, thereby ensuring the accuracy and stability of the height adjustment of the lubrication mechanism body 12. Then, lift... The main body 12 of the lubrication mechanism is raised, causing the rotating block 3 to move the first fixed tooth 32 upward, disengaging it from the second fixed tooth 33. This releases the locking state of the main body 12 of the lubrication mechanism, allowing it to rotate with the rotating block 3 and adjust the angle to ensure that the lubricating grease can accurately cover all the key lubrication points of the die-casting punch. Subsequently, through gravity and the elastic restoring force of the spring 4, the rotating block 3 and the first fixed tooth 32 are reset and re-engaged with the second fixed tooth 33 to form a firm locking structure, thus fixing the main body 12 of the lubrication mechanism and improving the installation efficiency of the lubrication mechanism of the die-casting punch.
