Abstract
Description
Technical Field
[0001] This utility model relates to the field of casting molding device technology, and in particular to an auxiliary platform device for casting molding. Background Technology
[0002] Casting molding refers to the process of creating a mold for pouring molten metal in casting production using molding materials and tools. Its core is to determine the shape and size of the casting by shaping the mold cavity. It usually includes steps such as pattern preparation, molding sand preparation, molding, core making, and mold assembly.
[0003] In the past, casting molders had to stand under or climb onto the sand box to perform tasks such as placing sand, inserting air holes, and compacting the sand mold. This was very inconvenient and posed a significant safety risk. Placing air holes and compacting the sand mold under the sand box was particularly difficult for molders. Because the sand box baffles were thin and the sand was slippery, there was no space to retreat or handrails around the molders when they climbed onto the sand box. This made them prone to slipping and falling, which could cause injuries.
[0004] Therefore, it is necessary to provide a new auxiliary platform device for casting molding to solve the above-mentioned technical problems. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides an auxiliary platform device for casting molding.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.
[0028] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0029] Please see Figures 1 to 5 An auxiliary platform device for casting molding is disclosed, comprising: a standing platform 1, with support rods 2 rotatably connected to both sides of the standing platform 1, steps 3 equidistantly installed inside the support rods 2, guardrails 4 fixedly connected to the top of the support rods 2 and the standing platform 1 for protection, a fixed seat 5 fixedly connected to the bottom of the standing platform 1, lifting plates 6 symmetrically installed at the bottom of the fixed seat 5 for lifting the standing platform 1, a lifting assembly for driving the lifting plates 6 to rise and fall inside the fixed seat 5, a rotating assembly for driving the steps 3 to rotate inside the support rods 2, casters 61 equidistantly installed at the bottom of the standing platform 1, and a rotating wheel 71 rotatably connected to the end of each set of support rods 2 away from the standing platform 1.
[0030] It should be noted that the casters 61 installed at equal intervals at the bottom of the standing platform 1 allow the entire platform to move freely on the ground, making it convenient for operators to move the platform to the position required for casting and molding. At the same time, the rotating wheels 71 connected to the ends of the multiple support rods 2 away from the standing platform 1 can play an auxiliary support and guiding role during the movement of the platform.
[0031] Please see Figure 1 and Figure 2 The lifting assembly includes: a drive motor 21, a rotating rod 22, a first worm gear 23, a first worm wheel 24, a threaded rod 25, and a lifting rod 26. The drive motor 21 is fixedly connected inside the fixed base 5. The rotating rod 22 is rotatably connected inside the fixed base 5. The output end of the drive motor 21 is fixedly connected to the rotating rod 22. The first worm gear 23 is symmetrically fixedly connected to the outer wall of the rotating rod 22. The first worm wheel 24 is symmetrically rotatably connected inside the fixed base 5. Both first worm wheels 24 mesh with the corresponding first worm gear 23. The threaded rod 25 is fixedly connected to the bottom of the first worm wheel 24. The lifting rod 26 is slidably connected inside the fixed base 5. The threaded rod 25 is threadedly connected to the lifting rod 26. The ends of the two lifting rods 26 away from the standing platform 1 are fixedly connected to the corresponding lifting plate 6.
[0032] It should be noted that the rotation of the threaded rod 25 causes the lifting rod 26 to slide up and down inside the fixed seat 5, which in turn drives the lifting plate 6 connected to the lifting rod 26 to rise and fall, thereby adjusting the height of the standing platform 1 to meet the casting molding work requirements at different heights.
[0033] Please see Figure 1 , Figure 3 , Figure 4 and Figure 5 The rotating assembly includes: a knob 31, a second worm 32, a second worm wheel 33, a connecting rod 34, a driving gear 35, a rack 36, and a driven gear 37. The second worm 32 is rotatably connected inside the support rod 2. One end of the second worm 32 passes through the support rod 2 and is fixedly connected to the knob 31. The second worm wheel 33 is rotatably connected inside the support rod 2. The second worm 32 meshes with the second worm wheel 33. The connecting rod 34 is fixedly connected to the axis of the second worm wheel 33. One end of the connecting rod 34 is fixedly connected to the driving gear 35. The rack 36 is slidably connected inside the support rod 2. The driven gear 37 is rotatably connected inside the support rod 2. Multiple sets of steps 3 are fixedly connected to the corresponding driving gear 35 and driven gear 37. The two knobs 31 are located at the end of the support rod 2 away from the standing platform 1.
[0034] It should be noted that when the height of the standing platform 1 changes, the height of the end of the support rod 2 that is rotatably connected to the standing platform 1 also changes, thus changing the angle between the support rod 2 and the ground. The top surface of the step 3 is no longer parallel to the ground. Therefore, the operator needs to rotate the knob 31 located at the end of the support rod 2 away from the standing platform 1. Both knobs 31 are located at the end of the support rod 2 away from the standing platform 1, so that the operator can easily access the knobs 31 even if the height of the standing platform 1 changes.
[0035] The working principle of the auxiliary platform device for casting molding provided by this utility model is as follows:
[0036] Mobile functionality:
[0037] The casters 61, which are equidistantly installed at the bottom of the standing platform 1, allow the entire platform to move freely on the ground, making it convenient for operators to move the platform to the position required for casting and molding. At the same time, the rotating wheels 71, which are rotatably connected to the ends of multiple support rods 2 away from the standing platform 1, can play an auxiliary support and guiding role during the movement of the platform, reducing movement resistance and making the movement more stable.
[0038] Lifting function:
[0039] When the height of the standing platform 1 needs to be adjusted, the drive motor 21 inside the fixed base 5 is started. The output end of the drive motor 21 drives the rotating rod 22 to rotate. The first worm 23, which is symmetrically fixed on the outer wall of the rotating rod 22, rotates accordingly. Since the first worm 23 meshes with the first worm wheel 24, the rotation of the first worm 23 will drive the first worm wheel 24 to rotate. The threaded rod 25 fixed at the bottom of the first worm wheel 24 also rotates. The threaded rod 25 is threadedly connected to the lifting rod 26. The rotation of the threaded rod 25 causes the lifting rod 26 to slide up and down inside the fixed base 5, thereby driving the lifting plate 6 connected to the lifting rod 26 to rise and fall, so as to realize the adjustment of the height of the standing platform 1 to adapt to the casting molding work requirements of different heights.
[0040] Step 3 Angle Adjustment Function:
[0041] When the height of the standing platform 1 changes, the height of the end of the support rod 2 that is rotatably connected to the standing platform 1 also changes, thus altering the angle between the support rod 2 and the ground. The top surface of the step 3 is no longer parallel to the ground. Therefore, the operator needs to rotate the knob 31 located at the end of the support rod 2 away from the standing platform 1. The knob 31 drives the second worm 32 to rotate. Because the second worm 32 meshes with the second worm wheel 33, the rotation of the second worm 32 drives the second worm wheel 33 to rotate. The connecting rod 34 fixed at the axis of the second worm wheel 33 rotates accordingly. The driving gear 35 fixed at one end of the connecting rod 34 also begins to rotate. The driving gear 35 cooperates with the rack 36 and the driven gear 37. When the driving gear 35 rotates, through the meshing transmission with the rack 36 and the driven gear 37, it drives multiple sets of steps 3 fixedly connected to the driving gear 35 and the driven gear 37 to rotate simultaneously, thereby adjusting the angle of the step 3. This makes it easier for the operator to climb the step 3 to the standing platform 1 for casting and molding operations.
[0042] Protective functions:
[0043] The railing 4, which is fixedly connected to the top of the standing platform 1 and the support rod 2, can provide protection for the operator, prevent the operator from falling accidentally while working on the platform, and ensure the safety of the operator.
