Description
Technical Field
[0001] This utility model relates to the field of mold technology, specifically to a casting mold for cast steel parts. Background Technology
[0002] Casting molds for steel parts are specialized molds used to shape cast steel parts. Their core function is to pour molten steel into a pre-designed cavity structure, which then cools and solidifies to form a metal part that meets the design requirements. The mold consists of a cavity and a core. Casting molds need to withstand the high temperature and erosion of molten steel, so they are usually made of high-temperature resistant materials. The design must consider venting and feeding systems to prevent porosity and shrinkage defects.
[0003] Excessively high molten steel melting temperature leads to increased hydrogen absorption. During solidification, the solubility decreases, causing hydrogen to precipitate and form bubbles. In existing technologies, venting ports or venting channels are usually set in the casting mold for venting. However, venting is slow and may even result in insufficient venting. When bubbles are not vented in time, they will create pores in the cast steel parts. These pores will reduce the effective load-bearing cross-sectional area of the casting, causing the actual stress to exceed the design value and greatly reducing the service life of the cast steel parts. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a casting mold for steel castings.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A casting mold for steel parts includes a mounting base, a mold placement box on the top of the mounting base, a support base and a support plate fixedly connected to the top of the mounting base, and a plurality of placement slots on the top of the mold placement box. A reciprocating assembly is provided outside the support base, the reciprocating assembly including a servo motor fixedly connected to the outside of the support base, a turntable fixedly connected to one end of the servo motor drive shaft, a positioning block fixedly connected to the side of the turntable away from the support base, a connecting plate fixedly connected to the outer circular wall of the positioning block, a connecting block fixedly connected to the bottom of the connecting plate, a movable plate movably sleeved on the outer circular wall of the connecting block, a limit hole provided on the side of the support plate near the movable plate, the limit hole being slidably connected to the movable plate, and a U-shaped plate movably sleeved on the side of the movable plate away from the support base, the U-shaped plate being fixedly connected to the mold placement box.
[0006] To prevent liquid from splashing out when the mold placement box shakes, as a casting mold for cast steel parts according to this utility model, preferably, the top of the mold placement box is fixedly connected to two fixing blocks, a connecting rod is fixedly connected between the two fixing blocks, a cover plate is movably sleeved on the outer circular wall of the connecting rod, and a fixing plate is fixedly connected to the side of the mold placement box near the fixing blocks.
[0007] To provide auxiliary support for the mold placement box, as a casting mold for cast steel parts according to this utility model, preferably, a positioning plate is fixedly connected to the top of the mounting base, and two support springs are fixedly connected to the side of the positioning plate near the mold placement box, and both support springs are fixedly connected to the mold placement box.
[0008] In order to accelerate the rate at which the temperature of the casting mold decreases during casting, as a casting mold for steel parts according to this utility model, preferably, a heat-conducting pad is fixedly connected inside the placement groove, and the casting mold is movably sleeved inside the heat-conducting pad.
[0009] In order to support and fix the casting mold, as a casting mold for steel parts according to this utility model, preferably, the top of the mounting base is provided with several threaded holes, and the inner circular wall of the threaded holes is threaded with threaded columns.
[0010] To prevent the mold from tipping over during reciprocating motion, as a casting mold for cast steel parts according to this utility model, preferably, the top of the mounting base has two T-shaped grooves, and the bottom of the mold placement box is fixedly connected to two T-shaped blocks, which are slidably connected to the T-shaped grooves.
[0011] In summary, the present invention has the following main advantages: 1. Based on the interaction between the casting mold, heat-conducting pad, servo motor, turntable, positioning block, connecting plate, moving plate, support plate, and U-shaped plate, the servo motor drives the turntable to rotate, which in turn drives the moving plate to pull the mold placement box in a reciprocating motion. This causes the liquid inside the casting mold to shake under the action of reciprocating motion and its own inertia. The shaking causes the gas inside the casting mold to turn into bubbles and be discharged, thus avoiding a reduction in the load-bearing capacity and airtightness of the cast steel parts and improving the finished product efficiency of the casting mold.
[0012] 2. Based on the interaction between the T-block, mold placement box, and T-slot, when the mold placement box reciprocates, the T-block reciprocates inside the T-slot. This prevents the mold placement box from shaking and tipping over when it reciprocates on top of the mounting base, which could cause liquid inside the casting mold to splash out, damaging the lifespan of the heat-conducting pad. This reduces the risk of production accidents during the casting mold's operation and improves the efficiency of the workers in casting molds.
[0013] 3. Based on the cooperation between the cover plate, fixing block, connecting rod and mold placement box, rotate the cover plate counterclockwise to cover the mold placement box. This prevents the liquid inside the casting mold from splashing out when the mold placement box reciprocates, thus reducing the risk of insufficient product quality. Attached Figure Description

[0016] 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.
[0017] Example: Reference Figure 1 , Figure 2 and Figure 3A casting mold for steel casting includes a mounting base 1, a mold placement box 2 on the top of the mounting base 1, a support base 3 and a support plate 10 fixedly connected to the top of the mounting base 1, a plurality of placement slots 17 on the top of the mold placement box 2, a reciprocating assembly including a servo motor 4 fixedly connected to the outside of the support base 3, a turntable 5 fixedly connected to one end of the drive shaft of the servo motor 4, a positioning block 6 fixedly connected to the side of the turntable 5 away from the support base 3, a connecting plate 7 fixedly connected to the outer circular wall of the positioning block 6, a connecting block 8 fixedly connected to the bottom of the connecting plate 7, and a movable plate 9 movably sleeved on the outer circular wall of the connecting block 8, with the support plate 10 close to the movable plate 9. A limiting hole 11 is provided on one side of the plate 9, and the limiting hole 11 is slidably connected to the movable plate 9. A U-shaped plate 12 is movably sleeved on the side of the movable plate 9 away from the support base 3. The U-shaped plate 12 is fixedly connected to the mold placement box 2. A positioning plate 20 is fixedly connected to the top of the mounting base 1. Two support springs 21 are fixedly connected to the side of the positioning plate 20 near the mold placement box 2. Both support springs 21 are fixedly connected to the mold placement box 2. Several threaded holes 22 are provided on the top of the mounting base 1. Threaded posts 23 are threadedly connected inside the threaded holes 22. Two T-shaped grooves 25 are provided on the top of the mounting base 1. Two T-shaped blocks 24 are fixedly connected to the bottom of the mold placement box 2. The T-shaped blocks 24 are slidably connected to the T-shaped grooves 25. According to the set casting mold 19, when it is necessary to make the mold placement box 2 shake to remove air bubbles, firstly, the mounting base 1 is fixed to the ground through the threaded hole 22 and threaded post 23. Then, the device is powered on. Then, the operator places the casting mold 19 into the interior of the heat-conducting pad 18, and then pours the alloy liquid into the casting mold 19. Then, the cover plate 15 covers the mold placement box 2. Then, the servo motor 4 is started. The drive shaft of the servo motor 4 rotates clockwise, driving the turntable 5 to rotate clockwise. Then, the positioning block 6 and the connecting plate 7 begin to rotate clockwise. Then, the connecting block 8 begins to move towards the support plate 10, and then the moving plate 9 begins to move towards the support plate 10. Then, the U-shaped plate 12 and the mold placement box 2 begin to move towards the positioning plate 20. Then, the mold placement box 2, the casting mold 19, and the support spring 21 move towards the positioning plate 20. Subsequently, the servo motor 4 continues to rotate clockwise, and then the positioning block 6 and the connecting plate 7 continue to rotate clockwise. Then, the connecting block 8 begins to move away from the support plate 10, and then the moving plate 9 begins to move away from the support plate 10. Subsequently, the U-shaped plate 12 and the mold placement box 2 begin to move away from the positioning plate 20. Then, the mold placement box 2, the casting mold 19, and the support spring 21 move away from the positioning plate 20. Under the action of reciprocating motion and its own inertia, the liquid in the casting mold 19 begins to shake. The shaking causes the gas in the casting mold 19 to turn into bubbles and be discharged, thus avoiding a reduction in the load-bearing capacity and airtightness of the cast steel parts.
[0018] According to the T-shaped block 24, when the mold placement box 2 moves towards the positioning plate 20, the T-shaped block 24 moves towards the positioning plate 20 inside the T-shaped groove 25. When the mold placement box 2 moves away from the positioning plate 20, the T-shaped block 24 moves away from the positioning plate 20 inside the T-shaped groove 25. This prevents the mold placement box 2 from tipping over when it reciprocates on the top of the mounting base 1, causing the liquid in the casting mold 19 to splash out and damage the service life of the heat-conducting pad 18.
[0019] refer to Figure 1 , Figure 2 and Figure 4 The top of the mold placement box 2 is fixedly connected to two fixing blocks 13, and a connecting rod 14 is fixedly connected between the two fixing blocks 13. A cover plate 15 is movably sleeved on the outer circular wall of the connecting rod 14. A fixing plate 16 is fixedly connected to the side of the mold placement box 2 near the fixing blocks 13. A heat-conducting pad 18 is fixedly connected inside the placement groove 17, and a casting mold 19 is movably sleeved inside the heat-conducting pad 18. According to the T-shaped block 24, when the mold placement box 2 moves towards the positioning plate 20, the T-shaped block 24 moves towards the positioning plate 20 inside the T-shaped groove 25. When the mold placement box 2 moves away from the positioning plate 20, the T-shaped block 24 moves away from the positioning plate 20 inside the T-shaped groove 25. This prevents the mold placement box 2 from tipping over when it reciprocates on the top of the mounting base 1, causing the liquid in the casting mold 19 to splash out and damage the service life of the heat-conducting pad 18.
[0020] Working principle: Please refer to Figures 1-4As shown, according to the set casting mold 19, when it is necessary to make the mold placement box 2 shake to remove air bubbles, firstly, the mounting base 1 is fixed to the ground through the threaded hole 22 and threaded post 23. Then, the device is powered on. Then, the operator places the casting mold 19 into the interior of the heat-conducting pad 18, and then pours the alloy liquid into the casting mold 19. Then, the cover plate 15 covers the mold placement box 2. Then, the servo motor 4 is started. The servo motor 4 drives the shaft to rotate clockwise, which drives the turntable 5 to rotate clockwise. Then, the positioning block 6 and the connecting plate 7 start to rotate clockwise. Then, the connecting block 8 starts to move towards the support plate 10. Then, the moving plate 9 starts to move towards the support plate 10. Then, the U-shaped plate 12 and the mold placement box 2 start to move towards the positioning plate 20. The movement causes the mold placement box 2, casting mold 19, and support spring 21 to move closer to the positioning plate 20. Then, the servo motor 4 continues to rotate clockwise, followed by the positioning block 6 and connecting plate 7. Then, the connecting block 8 begins to move away from the support plate 10, and the moving plate 9 begins to move away from the support plate 10. Then, the U-shaped plate 12 and mold placement box 2 begin to move away from the positioning plate 20. As a result, the liquid inside the casting mold 19 begins to sway due to the reciprocating motion and its own inertia. The swaying causes the gas inside the casting mold 19 to turn into bubbles and be discharged, thus avoiding a reduction in the load-bearing capacity and airtightness of the cast steel parts.
[0021] According to the T-shaped block 24, when the mold placement box 2 moves towards the positioning plate 20, the T-shaped block 24 moves towards the positioning plate 20 inside the T-shaped groove 25. When the mold placement box 2 moves away from the positioning plate 20, the T-shaped block 24 moves away from the positioning plate 20 inside the T-shaped groove 25. This prevents the mold placement box 2 from tipping over when it reciprocates on the top of the mounting base 1, causing the liquid in the casting mold 19 to splash out and damage the service life of the heat-conducting pad 18.
[0022] According to the cover plate 15, when it is necessary to reciprocate the casting mold 19 to remove air bubbles, the cover plate 15 is first rotated counterclockwise. The cover plate 15 starts to rotate counterclockwise around the fixed block 13. When the cover plate 15 is in contact with the mold placement box 2, the rotation of the cover plate 15 stops. The cover plate 15 is in close contact with the mold placement box 2 to prevent the liquid inside the casting mold 19 from splashing out when the mold placement box 2 is reciprocating, which would reduce the quality of the product cast by the casting mold 19.
[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
