Description

Technical Field

[0001] The utility model relates to the technical field of pump body product molds, in particular to a liquid forging mold with dustproof effect. Background Art

[0002] As an important part of the three hydraulic components, the pump body casting of the hydraulic gear pump is subjected to high pressure and impact during operation, so the casting performance requirements are high. Traditional pump bodies are generally formed by gravity casting, with low casting material utilization, large processing allowance, and average product performance. The liquid die forging process allows the casting to be formed under isostatic pressure, and the comprehensive performance of the casting is significantly improved, especially when the direct liquid die forging process is used. The pressure acts directly on the casting, reducing the impact of pressure loss on the casting performance. Direct liquid die forging generally adopts an upper and lower die structure.

[0003] For example, a liquid forging die with application number 202220315932.5 can cool the die, reduce demoulding resistance, and improve product production efficiency through the action of the flange sleeve and the core rod. Due to the inclination of the inner surface of the flange sleeve, the right die and the left die are continuously tightened during the tightening process, so that the product shape in the die cavity has no inclination. However, it is difficult for the device to achieve a good dustproof effect to reduce the impact of dust falling on the lower die before die forging on the quality of the finished die forging product, and it is difficult to adjust according to actual production needs.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a liquid forging die with dustproof effect is proposed. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-Figure 4As shown, a liquid forging die with dustproof effect comprises a bottom plate 1 and a lower die 2 arranged on the upper surface of the bottom plate 1, a plurality of screw holes 3 are opened on the upper surface of the bottom plate 1, a mounting hole 4 is arranged on the upper surface of the lower die 2 extending to the inside of the screw holes 3, an upper die 5 is arranged above the lower die 2, and dust suction mechanisms 6 are arranged on both sides of the lower die 2, the mounting holes 4 and the screw holes 3 are convenient for installing lower dies 2 of various sizes, the number of mounting holes 4 is four, distributed at the four corners of the upper surface of the lower die 2, the dust suction mechanism 6 comprises a support arm 61 slidably connected to the upper surface of the bottom plate 1, a dust suction pipe 62 is arranged on the inner side of the support arm 61, and the support arm 61 is provided with a dust suction pipe 62. The front and rear surfaces of the arm 61 are fixedly connected with an extension rod 63, one end of the extension rod 63 is rotatably connected with a pull rod 64, and the pull rod 64 is rotatably connected to the front and rear surfaces of the upper mold 5. An adjustment mechanism 65 is provided inside and outside the support arm 61. The adjustment mechanism 65 includes a threaded rod 651 threadedly connected to the inside of the support arm 61, one end of the threaded rod 651 is rotatably connected to a shell 652, a sliding rod 653 is fixedly connected to the outer surface of one side of the shell 652, and the sliding rod 653 is slidably connected to the inside of the support arm 61, the inside of the shell 652 is provided with a cavity connected to the inside of the dust suction pipe 62, and a joint is provided on the rear surface of the shell 652. The dust suction hose can be connected to the dust suction end of the dust suction device. A slide groove 621 is provided inside the dust suction tube 62. An extension tube 622 is slidably connected inside the slide groove 621. The upper surface of the dust suction tube 62 extends to the inner thread of the slide groove 621 and is connected to a locking screw 623. The outer surface of the extension tube 622 is fixedly connected to a limited slide bar. The limited slide bar can be slidably connected to the inside of the slide groove 621. When the upper mold 5 is driven downward by a hydraulic device, the pull rod 64 pushes the extension rod 63 and the support arm 61 to make the support arm 61 slide to both sides to prevent the dust suction mechanism 6 from affecting the normal die forging of the liquid die forging die, thereby effectively achieving the purpose of preventing the dust from being sucked away. In order to improve the dust removal effect, when the upper mold 5 is lifted upward, the upper mold 5 uses the pull rod 64 to pull the extension rod 63 and the support arm 61 closer to each other. During the approach process, the dust suction tube 62 and the extension tube 622 can suck the dust and debris on the lower surface of the lower mold 2. If lower molds 2 of different widths are installed, the locking screw 623 can be loosened to adjust the extension length of the extension tube 622 to adjust the overall dust suction length. The threaded rod 651 can also be used to adjust the spacing of the shell 652 to adapt to the lower mold 2 in different dust removal positions. The sliding rod 653 can assist in sliding during the adjustment process to prevent the shell 652 from rotating with the threaded rod 651.

[0022] like Figure 1 and Figure 2 As shown, the upper surface of the base plate 1 extends to the interior where a slide rail 7 is provided, the lower end of the support arm 61 is fixedly connected to a slider 8, and the slider 8 and the support arm 61 are respectively slidably connected to the inner and outer surfaces of the slide rail 7, and the upper and inner surfaces of the slide rail 7 can be coated with lubricating oil to reduce friction and prevent the pull rod 64 from causing the support arm 61 to bend.

[0023] Furthermore, a plurality of fixing holes 9 are provided on the front and rear surfaces of the upper mold 5 , and the pull rod 64 is rotatably connected to the front and rear outer surfaces of the upper mold 5 via a fixing screw.

[0024] Working principle: When using the liquid forging die with dustproof effect, first, when the upper die 5 is driven by the hydraulic device to press down, the pull rod 64 pushes the extension rod 63 and the support arm 61 to make the support arm 61 slide to both sides to prevent the dust suction mechanism 6 from affecting the normal die forging of the liquid forging die. When the upper die 5 is lifted up, the upper die 5 uses the pull rod 64 to pull the extension rod 63 and the support arm 61 closer to each other. During the approaching process, the dust suction pipe 62 and the extension pipe 622 can remove dust and debris from the lower surface of the lower die 2. If the lower die 2 of different widths is installed, the locking screw 623 can be loosened to lock the extension pipe 62. 2 can be adjusted by adjusting the extension length to adjust the overall dust suction length to achieve a better fit suction effect. The threaded rod 651 can also be used to adjust the spacing of the shell 652 to adapt to the lower mold 2 at different dust removal positions. The slide bar 653 can assist in sliding during the adjustment process to prevent the shell 652 from rotating with the threaded rod 651. When the pull rod 64 pushes and pulls the support arm 61, the slider 8 can slide inside the slide rail 7 to reduce friction. Changing the pull rod 64 to fix it in the fixing hole 9 at different positions can further reduce the use limitations of the device. This is the working principle of the liquid forging mold with dustproof effect.
