Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of wax model manufacturing coatings, in particular to a wax model manufacturing coating mixing device. Background Art
[0002] A wax mold is a mold used for casting molds. Specifically, since the wax mold can be easily removed, such as by calcination, unlike traditional mold making, the wax mold can not only produce precision castings with various shapes and complex structures, but also make casting simple, convenient and efficient.
[0003] In the production process of wax models, first of all, it is necessary to make silica sol adhesive. The adhesive mainly includes silane coupling agent alcohol glycol, organic alcohol, JFC wetting agent, polymethacrylate, latex and other high-viscosity adhesives. Then the adhesive is mixed with the coating to form a back layer coating (the back layer coating is made into a wax model through subsequent 3D printing technology). Among them, the coating includes inorganic materials such as manganese oxide and silicon oxide.
[0004] Therefore, in the process of mixing and preparing, when mixing adhesives with high viscosity and inorganic coatings, it is difficult for the two materials with relatively different physical and chemical properties to be fully mixed to form a uniform slurry back coating. This is manifested in that after a long period of mixing, the slurry contains lumps that cannot be easily dissolved. At present, for such lumps that are still difficult to dissolve after mixing, the only way is to increase the stirring and dissolving time, but this method undoubtedly increases the slurry making time. Moreover, for stubborn lumps, even if the stirring and dissolving time is increased, it is still difficult to fully dissolve them into the slurry.
[0005] Therefore, in the actual production process, if the homogenized slurry can be separated from the lumps while being prepared, it will not affect the wax film production. Secondly, by discharging the dissolved slurry, the undissolved material can be intercepted, and a part of the slurry can be retained to increase the stirring and disperse the lumps. This will ensure that the undissolved lumps are dispersed and dissolved as much as possible during the preparation process. Utility Model Content
[0006] Based on the above background, the purpose of the utility model is to provide a wax model manufacturing paint mixing device.

[0019] Preferably, a first pull plate is fixedly connected between the ends of a first long connecting screw rod disposed at the upper and lower parts, and a second pull plate is fixedly connected between the ends of a second long connecting screw rod disposed at the upper and lower parts.
[0020] Preferably, the filtering mechanism comprises an inner frame cylinder, and the inner frame cylinder is fixedly connected in the mixing cylinder;

[0024] The mesh diameter of the cylindrical filter is smaller than the hole width of the strip-shaped through hole.
[0025] The utility model has the following beneficial effects:
[0026] 1. During the working process, the materials are continuously dissolved, especially the inorganic materials and organic sizing materials are dispersed and dissolved. As the dissolution proceeds, the material pipe is opened. At this time, the materials are initially filtered from the strip through holes on the inner skeleton tube, filtered from the cylindrical filter screen, and enter the material pipe, enter the mixing cylinder in the secondary mixing mechanism of the wax model coating, and mix again in the same way. After mixing, the materials are discharged from the lower end of the side wall of the mixing cylinder of the secondary mixing mechanism to form a homogeneous slurry. The agglomerates that are not fully dissolved are easier to be impacted, refined and dissolved again by the stirring structure due to the reduced slurry volume and increased concentration. After stirring for a period of time, the valve on the material pipe is opened. This method is used to ensure that the dissolved slurry is quickly processed and discharged for use during the production process, and the agglomerates that are not fully dissolved are improved by increasing the concentration to improve the dissolution effect, and finally the agglomerates that cannot be dissolved are removed. This method not only does not affect the processing progress of the wax model during the production process, but also can concentrate the material blocks that are not fully dissolved in the material, thereby improving the processing effect.
[0027] 2. Through the structural design of the first and second refining grid plates, during the slurry preparation process, the materials with relatively small agglomerate particle sizes can be mixed in the slurry, and the densely arranged first and second refining grid plates are used to form a grid structure with relatively high density, so that the small agglomerated particles can be fully impacted and refined during the stirring process, especially after a part of the slurry is discharged, when the concentration of agglomerated materials in the slurry is increased, the stirring effect is very obvious, and the slurry can be homogenized again.
[0028] Furthermore, because the first fine mesh plate and the second fine mesh plate are oriented in different directions, during the rotation process, shear forces act on the material slurry at different angles and in different directions, thereby greatly improving the homogenizing effect.

[0040] Example 1
[0041] like Figure 1-6 As shown, a wax model manufacturing coating mixing device comprises a wax model coating preliminary mixing mechanism 1 and a wax model coating secondary mixing mechanism 2 assembled and connected to the wax model coating preliminary mixing mechanism 1. The material is first mixed in the wax model coating preliminary mixing mechanism, and the mixed slurry is pumped into the wax model coating secondary mixing mechanism 2 for further refinement and mixing.
[0042] Specifically, the wax model coating secondary mixing mechanism 2 and the wax model coating primary mixing mechanism 1 both include a mixing cylinder, and the lower end of the side wall of the mixing cylinder is connected through a material pipe (a valve is installed on the material pipe).
[0043] At the same time, a filtering mechanism is fixedly connected inside the mixing cylinder. During the mixing process, the coating slurry is filtered through the filtering mechanism and then transported, and the residue is discharged from the bottom of the mixing cylinder (according to the existing method, a connecting discharge pipe is installed at the bottom of the mixing cylinder, and a valve is installed on the discharge pipe).
[0044] Specifically, the filtering mechanism includes an inner frame tube 32 (the inner frame tube 32 is made of stainless steel, including a frame tube body 322, the top and bottom of the tube body 322 have flange structures 321, and the flange structure 321 is fixed on the inner side wall of the mixing tube), so that the outer side wall of the inner frame tube 32 is spaced from the inner side wall of the mixing tube. At the same time, a plurality of strip-shaped through holes 3221 are opened on the inner frame tube 32.
[0045] Furthermore, in order to improve the filtering effect, a cylindrical filter screen 33 is fixedly connected to the outer wall of the inner frame tube 32 ; the mesh diameter of the cylindrical filter screen 33 is smaller than the hole width of the strip-shaped through hole 3221 .
[0046] During the working process, the material is first mixed in the mixing cylinder of the wax model coating preliminary mixing mechanism 1 (according to the existing method, the mixing cylinder includes a cylinder body and a cylinder cover installed at the top of the cylinder body, and the cylinder cover is connected to a pumping pipe for pumping material).
[0047] During the mixing process, the material is continuously dissolved, especially the inorganic material and the organic glue are dispersed and dissolved. As the dissolution proceeds, the material pipe is opened. At this time, the material is initially filtered through the strip through hole 3221 on the inner skeleton tube 32, filtered through the cylindrical filter screen 33, and enters the material pipe 11, enters the mixing cylinder in the wax model coating secondary mixing mechanism 2, and is mixed again in the same way. After mixing, the material is discharged from the lower end of the side wall of the mixing cylinder of the secondary mixing mechanism as a homogeneous slurry (according to the existing method, a discharge pipe is connected to the lower end of the side wall of the mixing cylinder of the secondary mixing mechanism - not shown in the figure, for discharging the homogeneous slurry).
[0048] The agglomerates that have not been fully dissolved are more likely to be impacted, refined and dissolved again by the stirring structure when stirred because the slurry volume is reduced and the concentration is increased. After stirring for a period of time, the valve on the material pipe 11 is opened.
[0049] After repeating several times, the remaining agglomerated materials are trapped in the inner frame tube 32. At this time, the discharge pipe at the top of the mixing tube is opened to discharge the insoluble agglomerated materials.
[0050] This method can ensure that the dissolved slurry can be quickly processed and discharged for use during the production process, while the lumps that have not been fully dissolved can be improved by increasing the concentration to improve the dissolution effect, and finally the insoluble lumps can be removed.
[0051] In this way, after repeated primary and secondary wax model coating mixing processes, a large amount of highly homogeneous slurry is discharged.
[0052] In actual working process, the cylindrical filter screen 33 on the wax model coating secondary mixing mechanism 2 is designed to have a smaller filter hole, so as to obtain coating with relatively high quality.
[0053] Example 2
[0054] like Figure 1-6 As shown, in this embodiment, based on the structure of embodiment 1, a wax model coating refinement component 4 is assembled and connected to the above-mentioned mixing cylinder, and the wax model coating refinement component 4 includes a motor assembled and connected to the mixing cylinder (according to the existing method, the motor is installed on the cylinder cover, and its output shaft is rotatably connected to the cylinder cover and is connected to the material shaft by a coupling connection), and the motor is assembled and connected to the material shaft 311 rotatably connected in the mixing cylinder (same as the existing method, the material shaft 311 is rotatably connected to the bottom center of the mixing cylinder and is staggered from the position of the discharge hole at the bottom of the mixing cylinder).
[0055] In order to fully refine and mix the slurry, increase the homogenization effect, and improve the refinement and dispersion efficiency of lumps, the material shaft 311 is equipped with a grid refinement component located in the filtering mechanism, and the grid refinement component includes a first grid frame arranged with an upper and lower interval, and the first grid frame is vertically arranged with a second grid frame arranged with an upper and lower interval (the first grid frame and the second grid frame are vertically arranged in horizontal plane projection).
[0056] Specifically, the first grid frame includes first end seats 41 spaced apart from each other, and a first long connecting screw 42 is fixedly connected between the centers of the first end seats 41. The first long connecting screw 42 is fixedly connected to the material shaft 311 (penetrating the material shaft 311 and fixing the material shaft 311). At the same time, first mounting rods 44 spaced apart from each other are fixedly connected between the side walls of the first end seats 41 facing each other, and the upper and lower ends of the first refined grid plate 45 are respectively fixedly assembled and connected between the upper and lower first mounting rods 44 (a plurality of first refined grid plates 45 are fixedly connected between the first grid frames). The first refined grid plate 45 is made of a steel plate with a thickness of 1.2 mm, and its side faces are arranged to face left and right.
[0057] Similarly, the second grid frame includes second end seats 46 spaced apart in front and back, and a second long connecting screw 49 is fixedly connected between the centers of the second end seats 46. The second long connecting screw 49 is fixedly connected to the material shaft 311 (penetrating the material shaft 311 and fixing the material shaft 311).
[0058] The second mounting rods 47 are fixedly connected between the side walls of the second end seat 46 facing each other, and the upper and lower ends of the second refined grid plate 48 (with the same size and material as the first refined grid plate 45) are respectively fixedly assembled and connected between the upper and lower second mounting rods 47. The side surfaces of the second refined grid plate 48 are arranged to face forward and backward.
[0059] The purpose of the above design is: during the slurry preparation process, for materials with relatively small agglomerate particle sizes, they are mixed in the slurry, and a densely arranged first refining grid plate 45 and a second refining grid plate 48 are used to form a grid structure with relatively high density, so that during the stirring process, the small agglomerated particles can be fully impacted and refined, especially after a part of the slurry is discharged later, when the concentration of agglomerated materials in the slurry is increased, the stirring effect is very obvious, and the slurry can be homogenized again within 10 minutes.
[0060] Furthermore, because the first fine mesh plate 45 and the second fine mesh plate 48 face in different directions, during the rotation process, shear forces act on the material slurry at different angles and in different directions, thereby greatly improving the homogenizing effect.
[0061] Example 3
[0062] like Figure 1-5 As shown, in this embodiment, based on the structure of embodiment 2, a first pull plate 43 is fixedly connected between the ends of the first long connecting screw 42 at the upper and lower parts, and a second pull plate is fixedly connected between the ends of the second long connecting screw 49 at the upper and lower parts. The front and rear ends of the first pull plate and the second pull plate are respectively slidably connected to the ends of the corresponding long connecting screws and tightened with nuts.
[0063] In this way, the stability of the entire densely arranged grid stirring structure is increased.
[0064] 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.
