Description

Technical Field

[0001] The utility model relates to the technical field of mechanical parts manufacturing, in particular to a sand spraying device for a wax mold used for casting. Background Art

[0002] In the casting process, a common method for manufacturing precision castings is wax casting. Wax casting is a lost wax casting process. Its basic principle is to first make a wax pattern in a mold, then immerse the wax pattern in a refractory mixture to form a cladding, and finally melt the wax pattern and sinter the cladding to obtain a casting with a cavity.

[0003] After searching, the Chinese patent document announcement number: CN217941776U discloses a sand shower device for casting wax molds, which solves the problems that the sand particles in the sand shower work are not screened in advance, resulting in the agglomerated sand particles damaging the wax mold, and the sand particles that fail to participate in the sand shower work adhere to the glue and cause the sand particles to stick together and cannot be put into the sand shower operation again. The sand shower device includes a support frame, a collecting box is provided at the bottom inner side of the support frame, a feeding bin is welded on the inner side of the top of the support frame, a feeding port is welded on one side of the top of the feeding bin, a first motor is screwed to the top of the feeding bin, a sand screening plate is sleeved on the output end of the first motor, a sand screening net is welded on the inner side of the feeding bin, a collecting cover is welded on the inner side of the support frame, a motor plate is welded on the outer bottom of the collecting cover, and a second motor is screwed to the upper surface of the motor plate. The sand shower device can filter the sand particles participating in the sand shower operation in advance to prevent large particles and agglomerated sand particles from falling and damaging the wax mold.

[0004] Regarding the above-mentioned related technologies, the inventor believes that the above patent mentioned in the beneficial effects: "The sand shower device will re-screen the sand particles that failed to participate in the sand shower work, heat and knead the sand particles that are stuck together to disperse them, and discharge the sand particles that cannot be dispersed, so as to facilitate the screened sand particles to enter the sand shower work again."

Therefore, in view of the above shortcomings, a sand shower device for casting wax molds is proposed. Utility Model Content

The right side of one of the unloading plates 27 is fixedly connected with a heating box 28 for separating the drenching sand attached together;

[0029] The right side of another unloading plate 27 is fixedly connected with an inclined plate 29, and the left end of the inner wall of the bottom plate 1 is fixedly connected with a power assembly, which includes a motor 2 30, a driving source, and the outside of the motor 2 30 is fixedly connected to the inner wall of the left end of the bottom plate 1, so that the motor 2 30 can operate stably, and the driving end of the motor 2 30 is fixedly connected with a rotating shaft 31, and the rotating shaft 31 is driven by the driving motor 2 30 to rotate, and the top of the power assembly is fixedly connected with an eccentric wheel 32, and the top outer wall of the rotating shaft 31 is fixedly connected to the inner wall of the eccentric wheel 32, and the eccentric wheel 32 is driven by the rotating shaft 31 to rotate and hit the impact plate 33, and the bottom side of the collecting plate 22 is fixedly connected with the impact plate 33, and the collecting plate 22 is pushed to slide by the impact plate 33, and the outside of the power assembly is fixedly connected with an active plate 34;

[0030] The middle outer wall of the rotating shaft 31 is fixedly connected to the inner wall of the active plate 34, and the active plate 34 is driven to rotate by the rotating shaft 31. The outer part of the active plate 34 is sleeved with a belt 2 35, thereby driving the belt 2 35 to rotate. A square column 36 is fixedly connected to the right end of the top side of the bottom plate 1, and a square block 37 is fixedly connected to the bottom end of the inner wall of the square column 36. The inner wall of the square block 37 is rotatably connected to a driven plate 38. The driven plate 38 is restricted by the square block 37 so that it can rotate stably.

The top side of the driven plate 38 is fixedly connected with an auger 39 for easy transportation of sand. The left top end of the square column 36 is fixedly connected with a return plate 40 for easy sliding of sand.

[0031] Working principle: We pour the sand into the inside of the sand box 4 and use the support plate 5 to prevent the sand from being exposed. Then put the wax model with glue into the inside of the sand box 4. Then start the motor 8 to drive the rotating shaft 9 to rotate, thereby driving the connecting shaft 10 to rotate, and then drive the connecting sleeve 11 and the stirring column 12 outside the connecting sleeve 11 to fully mix the wax model and the sand. After the mixing is completed, the support plate 5 is pulled out, and the wax model and the sand will fall to the top side of the recovery plate 20. At this time, the wax model and the sand will be separated. At this time, the rotating shaft 9 will also drive the driving wheel 13 to rotate, thereby driving the belt 14 to rotate. Through the master-slave relationship, the belt 14 can drive the driven wheel 17 to rotate outside the driven rod 16, and drive the rubber column 18 to hit the recovery plate 20, so that the wax model and the sand are separated;

[0032] At this time, the drenched sand will fall to the top of the collecting plate 1 21, and the sand adhered to each other will accumulate on the top of the collecting plate 1 21, and the sand adhered to each other will fall to the top of the collecting plate 2 22. At this time, the rotating shaft 31 is driven to rotate by starting the motor 2 30, thereby driving the eccentric wheel 32 to rotate and push the impact plate 33 to slide to the right. At this time, the impact plate 33 will drive the collecting plate 22 and the collecting plate 1 21 and the connecting block 23 to slide to the right together, thereby pushing the sliding block 24 to slide on the outside of the support rod 25 and squeeze the strong spring 26, so that the strong spring 26 can store elastic potential energy and can reset when it is no longer under force, cooperating with each other. It can perform reciprocating motion, and the attached sand will slide to the top of the unloading plate 27 through the collecting plate 1 21, and then pass through the heating box 28 to disperse it and the unattached sand will slide to the top of the unloading plate 27 through the collecting plate 22, and then flow through the inclined plate 29 and fall into the inside of the square column 36. At this time, the rotating shaft 31 will also drive the active plate 34 to rotate, thereby driving the belt 2 35 to rotate, and then drive the driven plate 38 to rotate, so that the auger 39 can rotate to transport the sand upward, and then fall into the inside of the hopper 6 through the reflux plate 40. At this time, the support plate 5 is forked on the inner wall of the sand box 4 to provide support for the sand.
