Description

Technical Field

[0001] The utility model relates to the technical field of wax pattern casting, in particular to a wax pattern slurry dipping device for casting. Background Art

[0002] Wax casting is a lost foam casting process. According to the shape of the required casting workpiece, a wax mold is made in advance. Then, with the help of a slurry dipping machine, the wax mold is soaked to make its surface slurry. The slurry is then used to cover the surface of the wax mold with complex crystal sand. After drying, molten wax casting can be carried out.

[0003] In the prior art, a wax mold is assisted in slurry dipping by a slurry dipping machine. Although there are many large-scale advanced automated equipment for wax mold dipping nowadays, most small and medium-sized enterprises still use manual slurry dipping, in which the staff holds the wax mold and dips it in the slurry dipping machine. Since the slurry barrel of the slurry dipping machine has a limited depth, some wax molds with relatively long lengths are often encountered during the slurry dipping process. If you are not very careful, it is easy to push the wax mold against the bottom of the inner wall of the slurry barrel, and the constantly rotating slurry barrel will wear and deform the wax mold, causing the wax mold to be damaged and unusable. This process relies entirely on manual attention, which requires a high level of technical skills from the staff. There are deficiencies and need to be improved. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a wax mold dipping device for casting, which is used to solve the problem that the existing dipping machine is prone to push the wax mold against the bottom of the inner wall of the slurry barrel when manually dipping the wax mold with a longer length, causing the wax mold to be damaged and unusable.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] A wax pattern slurry dipping device for casting comprises a barrel shell, a rotary drive assembly installed in the barrel shell, and a slurry barrel rotatably installed in the barrel shell and transmission-connected to the rotary drive assembly, the top of the barrel shell is fixedly connected to a fixing frame, a scraper in contact with the inner wall of the slurry barrel is fixedly installed on the fixing frame, an inclined guide plate is fixedly connected to the bottom of the scraper, a gauze partition is arranged at a position near the bottom of the slurry barrel, and hanging ropes connected to the inner wall of the slurry barrel are equidistantly arranged on the edge of the gauze partition.

[0007] Preferably, the top of the barrel shell is provided with an inwardly folded eaves, the inner diameter of the central opening of the eaves is smaller than the outer diameter of the slurry barrel, and the side of the eaves close to the center of the barrel shell is inclined downward.

[0008] Preferably, the top of the slurry barrel is provided with an inwardly folded material-blocking flange, and the side of the material-blocking flange close to the center of the slurry barrel is inclined downward.

[0009] Preferably, the squeegee is vertically arranged, and one side of the squeegee corresponding to the upstream of the rotation direction of the slurry bucket is in contact with the inner wall of the slurry bucket.

[0010] Preferably, the deflector is horizontally arranged along the radial direction of the slurry bucket, and the height of one side of the deflector corresponding to the upstream of the rotation direction of the slurry bucket is less than the height of the side corresponding to the downstream of the rotation direction of the slurry bucket.

[0011] Preferably, the length of the deflector is less than the distance between the gauze partition and the inner side wall of the slurry bucket.

[0012] Preferably, hooks are equidistantly arranged along the circumferential direction on the inner side wall of the slurry bucket, and the suspension ropes are connected to the hooks.

[0013] Preferably, the bottom of the gauze partition and the suspension rope are fixedly connected with downwardly hanging beating ropes.

[0014] Preferably, an annular track is further installed on the inner side wall of the barrel housing, and a limit slider slidably connected to the annular track is fixedly installed on the outer wall of the slurry bucket.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] By arranging a layer of gauze partition at a position close to the bottom inside the slurry bucket, when the staff holds the wax mold for dipping slurry, if the wax mold touches the gauze partition, the staff can immediately feel it, and then stop inserting the wax mold downward. Instead, the staff adjusts the horizontal angle of the wax mold to fully dip the wax mold. The gauze partition is made of a flexible material and will not damage the wax mold when in brief contact with the wax mold. Thus, the effect of protecting the wax mold is achieved, the requirement for the manual technical level is reduced, and the use is simpler, more convenient, and easier. It solves the problem that the existing dipping machine is likely to push the wax mold against the bottom of the inner wall of the slurry bucket and cause damage to the wax mold and make it unusable when manually dipping a wax mold with a relatively large length.

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] As Figures 1-5 shown, the present invention provides a technical solution: a wax mold dipping device for casting, including a barrel body shell 1, a rotary drive assembly 2 installed inside the barrel body shell 1, and a slurry barrel 3 rotatably installed inside the barrel body shell 1 and drivingly connected to the rotary drive assembly 2. The top of the barrel body shell 1 is provided with an inwardly folded flange 101, and the inner diameter of the central opening of the flange 101 is smaller than the outer diameter of the slurry barrel 3. During the process of taking out the wax mold from the slurry barrel 3, the excess slurry on the surface of the wax mold is likely to drip down. The flange 101 can prevent the dripping slurry from entering between the barrel body shell 1 and the slurry barrel 3 and causing pollution, and the side of the flange 101 close to the center of the barrel body shell 1 slopes downward, which helps the slurry dripping from the wax mold to flow into the slurry barrel 3;

[0025] The top of the slurry barrel 3 is provided with an inwardly folded material baffle flange 301, and the side of the material baffle flange 301 close to the center of the slurry barrel 3 slopes downward. When the slurry barrel 3 rotates, a centrifugal force is generated on the slurry. The material baffle flange 301 can prevent the slurry near the inner wall of the slurry barrel 3 from overflowing outward. An annular track 11 is also installed on the inner wall of the barrel body shell 1, and a limit slider 12 slidably connected to the annular track 11 is fixedly installed on the outer wall of the slurry barrel 3;

[0026] The top of the barrel body shell 1 is fixedly connected with a fixed frame 4, and a scraper 5 in contact with the inner wall of the slurry barrel 3 is fixedly installed on the fixed frame 4. The scraper 5 is vertically arranged, and the side of the scraper 5 corresponding to the upstream of the rotation direction of the slurry barrel 3 is in contact with the inner wall of the slurry barrel 3 to prevent the slurry from condensing on the inner wall of the slurry barrel 3. The bottom of the scraper 5 is fixedly connected with an inclined deflector 6. The deflector 6 is horizontally arranged along the radial direction of the slurry barrel 3, and the height of the side of the deflector 6 corresponding to the upstream of the rotation direction of the slurry barrel 3 is less than the height of the side corresponding to the downstream of the rotation direction of the slurry barrel 3, which promotes the upward flow of the slurry below the slurry barrel 3 and promotes the uniform mixing of the slurry. The length of the deflector 6 is less than the distance between the gauze partition 7 and the inner wall of the slurry barrel 3;

[0027] A gauze partition 7 is provided at a position near the bottom inside the slurry bucket 3. Hanging ropes 8 connected to the inner side wall of the slurry bucket 3 are equidistantly arranged at the edge of the gauze partition 7. Hooks 9 are equidistantly arranged along the circumference on the inner side wall of the slurry bucket 3. The hanging ropes 8 are connected to the hooks 9. Dosing ropes 10 that hang down are fixedly connected to the bottom of both the gauze partition 7 and the hanging ropes 8, preventing the slurry flow rate from being slow under the gauze partition 7, resulting in an increase in concentration, and promoting uniform mixing of the slurry.

[0028] Working principle:

[0029] The rotary drive assembly 2 drives the slurry bucket 3 filled with slurry to rotate at a high speed, driving the slurry to mix. The scraper 5 prevents the slurry from condensing on the inner wall of the slurry bucket 3. The deflector 6 promotes the upward flow of the slurry below the inner part of the slurry bucket 3. The dosing ropes 10 prevent the slurry flow rate from being slow under the gauze partition 7, resulting in an increase in concentration, and promoting uniform mixing of the slurry. When a staff member holds a wax mold to dip it in the slurry, if the wax mold touches the gauze partition 7, the staff member can immediately feel it, and then no longer continues to insert the wax mold downward. Instead, the staff member adjusts the horizontal angle of the wax mold to dip the wax mold comprehensively. The gauze partition 7 is made of a flexible material and will not damage the wax mold when in brief contact with the wax mold, achieving the effect of protecting the wax mold.
