Description

Technical Field

[0001] The utility model belongs to the technical field of mold demoulding, and in particular relates to a precision casting vibration demoulding device. Background Art

[0002] Casting workpieces are industrial workpieces produced by pouring. Casting workpieces are mostly suitable for processing accessories with relatively large thickness, relatively complex shapes, and relatively high precision. Among them, the wax mold casting method is relatively energy-saving and environmentally friendly, and is suitable for processing accessories with a variety of complex shapes. Specifically, after the wax mold is formed, the slurry is hung to form the mold shell, and then the wax mold is removed by heat treatment methods such as steam to obtain a high-temperature resistant and relatively high-precision mold shell. During the pouring process, the pouring liquid is poured into the mold shell.

[0003] Then, the mold shell that can be broken and removed is removed by demolding to obtain the demolded workpiece. In the production process, due to the accessories of wax mold processing, especially the accessories with small processing size, a large number of accessories can only be placed in the container during demolding, and the container is vibrated to demold by vibration. However, in actual processing, after vibration, too much mold shell material remains on the workpiece. Therefore, it takes a long time and increased vibration intensity to completely remove the mold shell.

[0004] However, this method not only consumes too much energy, but also takes a long time to demould, especially for thin workpieces with slightly poor strength. Long-term high-intensity vibration demoulding can easily cause damage to the inside of the workpiece.

[0005] Therefore, in the production and processing process, for the above-mentioned situation, a large number of workpieces with insufficient demoulding can only be demoulded manually. However, since most of the workpieces are irregularly shaped products, manual demoulding is not only difficult to operate, but also very inefficient. At the same time, the mold shell material has a certain adhesion strength, so demoulding is very troublesome. Therefore, this method can only be applied to a small number of defective products. As for a large number of defective products with insufficient demoulding during the production process, this method obviously cannot effectively solve the problem. Utility Model Content

[0006] Based on the above background, the purpose of the utility model is to provide a precision casting vibration demoulding device.

[0007] In order to achieve the above objectives, the utility model adopts the following technical solutions:

[0008] A precision casting vibration demoulding device comprises a demoulding cylinder, the top of which is equipped with a vibration motor mechanism;

[0009] The demoulding cylinder is equipped with a demoulding auxiliary tooling, and the demoulding auxiliary tooling includes an annular fixing seat fixedly assembled in the demoulding cylinder, a plurality of baffles are fixedly connected in the annular fixing seat, and a demoulding plate is fixedly connected to the top of the baffle;

[0015] Preferably, a plurality of connecting mounting plates are welded to the bottom of the fixed mounting ring plate.

[0016] Preferably, the stripper plate is welded to the stripper plate;

[0017] The longitudinal cross-section of the stripping head is trapezoidal in shape, and the stripping heads are staggered on the stripping plate.

[0018] Preferably, the demoulding cylinder comprises a cylindrical portion; the cylindrical portion is integrally formed with a conical portion, and the bottom of the conical portion is a molding sand discharge port.

[0019] Preferably, a shell crushing mechanism is installed and connected in the conical portion, and the shell crushing mechanism includes a plurality of shell crushing tool plates arranged obliquely;

[0020] The bottom of the shell breaking tool plate is fixedly connected to the lower rotating base;

[0022] Preferably, a connecting frame is fixedly connected to the driving motor, and the connecting frame includes a fixed mounting plate fixedly mounted on the motor, a plurality of connecting columns are fixedly connected to the top of the fixed mounting plate, and the connecting columns are fixedly connected to the bottom of the conical portion.

[0023] Preferably, a conical material guide plate is fixedly connected between the connecting columns, and the output shaft of the motor is rotatably connected to the conical material guide plate;

[0024] During the unloading process, the mold sand broken by the mold shell is unloaded from the conical part, falls onto the conical guide plate, and unloads along the slope surface of the conical guide plate.

[0026] 1. Through the demoulding auxiliary tooling, specifically, the demoulding auxiliary tooling includes an annular fixing seat fixedly assembled in the demoulding cylinder, a number of baffles are fixedly connected in the annular fixing seat, and a demoulding plate is welded to the top of the baffle. During the vibration process, the demoulding effect is increased by the demoulding plate contacting the mold shell of the mold product. During the vibration process, the upper end of the demoulding head is a small end face, so it contacts the mold, and during vibration, it continuously impacts the mold shell to effectively remove the mold shell.

This method can refine the demoulded mold shell and facilitate the recycling of the mold shell sand.

[0028] 3. The conical guide plate is fixedly connected between the connecting columns, so that during the unloading process, the mold sand of the broken mold shell is unloaded from the conical part, falls onto the conical guide plate, and unloads along the slope of the conical guide plate. This method makes it convenient to unload the mold shell sand along the conical guide plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Example 1

[0041] like Figure 1-6As shown, a precision casting vibration demoulding device includes a demoulding cylinder, and the shape of the demoulding cylinder is: the demoulding cylinder includes a cylindrical portion 11; the cylindrical portion 11 is integrally formed with a conical portion 12 (welded to the bottom position of the cylindrical portion 11 in a sealed welding manner), and the bottom of the conical portion 12 is a molding sand discharge port.

[0042] According to the existing vibration mode, the top of the demoulding cylinder is equipped with a vibration motor mechanism. Specifically, the top of the demoulding cylinder is fixedly connected with a vibration beam rod, and the vibration motor mechanism includes a vibration motor 2, and the vibration motor 2 is fixedly installed on the vibration beam rod.

[0043] During operation, after the vibration motor 2 is started, the entire demoulding cylinder vibrates. Similar to the existing vibration mechanical structure, the cylinder mouth of the above-mentioned demoulding cylinder is fixedly connected with an annular flange plate 111, and the annular flange plate 111 is assembled and connected with a fixed mounting ring plate 4 through a plurality of spring members 3 (according to the existing method, a plurality of connecting mounting plates are welded to the bottom of the fixed mounting ring plate 4. The entire device is installed on the frame through the connecting mounting plates).

[0044] Specifically, the spring member 3 includes a reinforcing spring fixedly connected between the fixed mounting ring plate 4 and the annular flange plate 111, and the spring member 3 also includes a spring column fixedly connected to the bottom position of the annular flange plate 111, and the spring column is sleeved into the spring cavity of the reinforcing spring. Specifically, the spring column is inserted into the upper end position of the spring cavity of the reinforcing spring. Under the vibration of the vibration motor 2, the demoulding cylinder vibrates, and with the assistance of the reinforcing spring, the vibration intensity and vibration amplitude are relatively large, so that the mold product placed in the demoulding cylinder can be fully vibrated.

[0045] At the same time, in order to improve the demoulding effect by vibration, a demoulding auxiliary tooling is assembled and connected in the demoulding cylinder, and the demoulding auxiliary tooling includes an annular fixing seat 51 fixedly assembled in the demoulding cylinder, and a plurality of baffles 52 are fixedly connected in the annular fixing seat 51 (the baffles 52 are steel plates fixed by welding), and a demoulding plate 53 is welded and connected to the top of the baffles 52. During the vibration process, the demoulding effect is increased by contacting the mold shell of the mold product through the demoulding plate 53. Specifically, the demoulding plate 53 is a steel plate with a thickness of 1.2 cm, and a demoulding head is integrally formed at the upper end. During the vibration process, the upper end of the demoulding head is a small end face, so it contacts the mold, and during vibration, it continuously impacts the mold shell to effectively remove the mold shell. In addition, because the shape of the demoulding head is a trapezoid, not a sharp angle design, it will not damage the workpiece.

[0046] Example 2

[0047] like Figure 1-6As shown, based on the structure of Example 1, in order to improve the demoulding effect, the demoulding heads are staggered on the demoulding plate 53. The staggered arrangement is as follows: the orientations of the demoulding plates 53 are different, and thus the orientations of the demoulding heads are different, so that the molded product being discharged can fully contact the demoulding plates 53 in different orientations regardless of the posture.

[0048] Example 3

[0049] like Figure 1-6 As shown, based on the structure of Example 2, the mold shell material of this embodiment can be recycled as mold sand. Therefore, in order to realize the recycling of the mold shell, the above-mentioned demoulding auxiliary tooling also includes an annular convex plate 55 fixedly connected to the bottom position of the annular fixing seat 51, and a plurality of screening rods 54 are fixedly connected to the annular convex plate 55. Specifically, after the initial demoulding, the larger mold shell falls from the larger gap between the baffle plates 52 onto the screening rod 54. At this time, because the entire equipment is in a vibrating state, the mold shell material with a relatively high brittleness is further refined under vibration and enters the tapered portion 12.

[0050] Example 4

[0051] like Figure 1-6 As shown, based on the structure of Example 3, the above-mentioned conical portion 12 is equipped with a mold shell crushing mechanism, and the mold shell crushing mechanism includes a plurality of inclined (the inclination angle corresponds to the conical inclination angle of the conical portion 12) shell breaking tool plates 81 (distributed in a circular array); the shell breaking tool plates 81 are processed by a light alloy material with relatively high hardness.

[0052] At the same time, annular connecting rods 82 spaced apart in upper and lower directions are welded between the shell-breaking tool plates 81 to fix all the shell-breaking tool plates 81 in an integrated manner.

[0053] The bottom of the shell breaking tool plate 81 is fixedly connected to the lower rotating base 83; and the lower rotating base 83 maintains a distance from the feeding opening at the bottom of the conical portion 12, and the gap between the lower rotating base 83 and the feeding opening of the conical portion 12 is where the feeding gap is located.

[0054] Meanwhile, the bottom of the lower rotating base 83 is assembled and connected with a driving motor 6. The driving motor 6 is fixedly connected with a connecting frame, which includes a fixed mounting plate fixedly mounted on the motor, and a plurality of connecting columns 61 are fixedly connected to the top of the fixed mounting plate, and the connecting columns 61 are fixedly connected to the bottom of the conical portion 12 (specifically, an annular mouth plate is welded on the bottom material opening of the conical portion 12, and the connecting columns 61 are fixed to the annular mouth plate).

[0055] During the working process, driven by the motor, the shell breaking tool plate 81 designed with light alloy material rotates in the cavity of the conical part 12 (the design with light alloy material not only has high rotation flexibility, but also relatively large rotation stability), and the large pieces of mold shell that enter the cavity of the conical part 12 collide with the shell breaking tool plate 81 during the rotation process. This method quickly crushes and refines the mold shell material with greater brittleness in a stir-frying manner, and the refined material is discharged from the gap between the lower rotating base 83 and the discharge port of the conical part 12.

[0056] Meanwhile, in the process of turning and crushing, in order to improve the crushing effect, a plurality of crushing openings 811 are provided on the shell-breaking tool plate 81, and the formation of the crushing openings 811 increases the crushing effect.

[0057] Example 5

[0058] like Figure 1-6 As shown, in this embodiment, based on the structure of embodiment 3, a conical guide plate is fixedly connected between the connecting columns 61, and the output shaft of the motor is rotatably connected to the conical guide plate 7. During the material discharge process, the mold sand of the mold shell is discharged from the conical portion 12, falls onto the conical guide plate 7, and is discharged along the slope surface of the conical guide plate 7. In this way, it is convenient to discharge the mold shell sand along the conical guide plate 7. At the same time, because the conical guide plate 7 passes through the connecting column 61 and is welded to the connecting column 61, as a supporting structure, according to the existing method, a mounting hole is opened at the top of the conical guide plate 7, and a bearing is installed in the mounting hole. The output shaft of the motor is installed on the bearing, so that the rotation stability of the shell breaking tool plate 81 is increased when the motor rotates and crushes.

[0059] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
