Description

Technical Field

[0001] The invention relates to the technical field of composite permanent magnetic material processing, in particular to a composite permanent magnetic material casting machine. Background Art

[0002] Composite permanent magnetic materials are made of permanent magnetic material powder and plastic material as a binder. Because it contains a certain proportion of binder, its magnetic properties are significantly lower than those of the corresponding magnetic materials without binder. Except for metal composite permanent magnetic materials, other composite permanent magnetic materials are limited by the heat resistance of the binder and have a low use temperature, generally not exceeding 150°C. However, composite permanent magnetic materials have high dimensional accuracy, good mechanical properties, good uniformity of performance of each part of the magnet, and are easy to radially orient and multi-pole magnetize. It is mainly used in the manufacture of instruments and meters, communication equipment, rotating machinery, magnetic therapy equipment and sports equipment.

[0003] Some of the composite permanent magnetic materials are composed of magnetic material and high polymers such as rubber or plastic. During the pouring process, the composite material is fully stirred inside the pouring tank, poured into the mold through the pouring port, and then compression molded. The composite permanent magnetic material composed of magnetic material and high polymers such as rubber or plastic has a certain viscosity and poor fluidity. Therefore, it is easy to adhere to the surface of the stirring blade during the stirring process, affecting the fluidity of the material on the surface of the stirring blade, thereby reducing the mixing effect of the material and the pouring efficiency.

[0004] Therefore, a composite permanent magnetic material casting machine is proposed. Summary of the invention

[0005] The object of the present invention is to provide a composite permanent magnetic material casting machine, which can scrape and rotate the surface of the stirring blade when the stirring blade stirs the material by arranging a rotating component, thereby reducing the probability of the material adhering to the surface of the stirring blade and improving its fluidity, and can utilize the rotation of the movable rod to fully stir the material, thereby improving the mixing effect and casting effect of the device, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a composite permanent magnetic material casting machine, comprising a storage barrel, a feed pipe, a casting pipe, a support frame, a control valve, a stirring assembly and a rotating assembly, wherein the upper end outer surface of the storage barrel is fixedly connected with the feed pipe at a position close to one side, and the stirring assembly is arranged inside the storage barrel, the support frame is fixedly connected to the lower end outer surface of the storage barrel, the number of the rotating assemblies is several groups, and the several groups of the rotating assemblies are equidistantly arranged on one side of the inner surface of the storage barrel;

[0007] The stirring assembly includes a motor, a rotating rod and a stirring blade, and the motor is fixedly connected to the upper end outer surface of the storage barrel near the middle, the output shaft of the motor passes through the interior of the storage barrel and is fixedly connected to the rotating rod, and the rotating rod is rotatably connected to the storage barrel, the outer surface of the rotating rod is fixedly connected to the stirring blade, the lower end outer surface of the storage barrel is fixedly connected to a pouring pipe near the middle, the inner surface of the pouring pipe is communicated with the inner surface of the storage barrel, and a control valve is fixedly connected to the outer surface of one side of the pouring pipe.

[0008] By setting up a rotating component, the surface of the stirring blade can be scraped and rotated during the process of stirring the material by the stirring blade, thereby reducing the probability of the material adhering to the surface of the stirring blade and improving its fluidity. The material can also be fully stirred by the rotation of the movable rod, thereby improving the mixing effect and casting effect of the device.

[0009] Preferably, the rotating assembly includes a connecting block, a movable rod, a hinge and a scraper, the connecting block is hinged to the inner surface of the storage barrel by a hinge, and the movable rod is arranged at one end of the connecting block away from the hinge, the other end of the movable rod away from the connecting block extends to the upper outer surface of the mixing blade, and the outer surface of the movable rod is in contact with the mixing blade at a position where a plurality of groups of scrapers are fixedly connected in an equidistant ring, the outer surface of the scraper is tightly fitted with the upper outer surface of the mixing blade, the mixing blade is spiral, and the top view of the mixing blade is elliptical, and the movable rod is located on one side of the rotating rod and is offset therefrom.

[0010] During operation, the material enters the storage barrel through the feed pipe. At this time, the output shaft of the motor drives the rotating rod and the stirring blade on its surface to rotate counterclockwise to stir the material, and in this process the movable rod is located on the surface of the stirring blade. Therefore, during the counterclockwise rotation of the stirring blade, the scraper and the stirring blade move relative to each other to scrape its surface, and the top view of the stirring blade is elliptical, and the movable rod is located on one side of the rotating rod and is misaligned with it. Therefore, during the rotation of the stirring blade, the movable rod will disengage from it and drive the connecting block to rotate downward around the hinge and fall on the surface of the stirring blade again to collide with the stirring blade and produce vibration, thereby reducing the probability of material adhesion on the upper and lower surfaces of the stirring blade and improving the fluidity of the material. Then the movable rod moves relative to the stirring blade again and uses the scraper on its surface to scrape the surface of the stirring blade. In this process, since the stirring blade is spiral, the movable rod drives the connecting block to rotate around the hinge, and the evenly stirred material flows into the interior of the mold through the casting tube and then is die-cast.

[0011] Preferably, the cross-section of the connecting block is a right-angled trapezoid. In a natural state, the inclined surface of the connecting block fits tightly against the inner surface of the storage barrel. A rotation groove is provided on the side of the outer surface of the connecting block that is connected to the movable rod. One end of the movable rod passes through the interior of the rotation groove and is rotatably connected thereto. The cross-section of the rotation groove is T-shaped. Several groups of teeth are fixedly connected to the outer surface of the upper end of the stirring blade at a high position near the edge, and the scraper and the teeth are meshed with each other.

[0012] During the counterclockwise rotation of the stirring blade, the scraper and the stirring blade move relative to each other to scrape its surface. At the same time, a plurality of groups of teeth are fixedly connected to the upper end outer surface of the stirring blade at a high position near the edge and mesh with the scraper, and the movable rod is rotatably connected to the connecting block. Therefore, during the rotation of the stirring blade, the movable rod moves relative to the surface of the stirring blade and rotates, thereby improving the scraping effect of the scraper while stirring the material, thereby improving the mixing effect of the material.

[0013] Preferably, a mounting groove is provided at the connection between the inner surface of the material storage barrel and the connecting block, and an arc-shaped spring piece is fixedly connected to the inner surface of the mounting groove. The arc-shaped spring piece protrudes toward the interior of the material storage barrel in a natural state, and one side of the outer surface is located inside the material storage barrel.

[0014] By adopting the above technical solution, during the rotation of the stirring blade, the movable rod will disengage from the stirring blade and drive the connecting block to rotate downward around the hinge and fall on the surface of the stirring blade again to collide with the stirring blade to generate vibration. In this process, the movable rod drives the connecting block to rotate around and collide with the inner wall of the storage barrel. Therefore, by setting an arc-shaped spring piece, the force of the collision between the connecting block and the inner wall of the storage barrel can be effectively reduced, and the vibration frequency of the movable rod can be increased by squeezing and rebounding the arc-shaped spring piece, thereby ensuring the service life of the connecting block and the scraping and stirring effect of the movable rod.

[0015] Preferably, a heating chamber for storing heat transfer oil is opened inside the movable rod, and a heating wire is fixedly connected inside the heating chamber, an electric storage component is embedded and fixedly connected inside the movable rod, and the electric storage component is electrically connected to the heating wire, the scraper and the movable rod are an integrated structure, and the inner surface of the heating chamber passes through the interior of the scraper.

[0016] By opening a heating chamber inside the movable rod, the material can be heated in the process of the movable rod rotating and driving the scraper to scrape the surface of the stirring blade, thereby reducing the probability of the material adhering to the movable rod and the scraper rod surface, improving the fluidity of the material, and thus ensuring the casting effect of the device.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] By setting up a rotating component, the surface of the stirring blade can be scraped and rotated during the process of stirring the material by the stirring blade, thereby reducing the probability of the material adhering to the surface of the stirring blade and improving its fluidity. The material can also be fully stirred by the rotation of the movable rod, thereby improving the mixing effect and casting effect of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] By setting up the rotating component 7, the surface of the stirring blade 63 can be scraped and rotated during the process of the stirring blade 63 stirring the material, thereby reducing the probability of the material adhering to the surface of the stirring blade 63 and improving its fluidity, and the material can be fully stirred by the rotation of the movable rod 72, thereby improving the mixing effect and casting effect of the device.

[0029] As an embodiment of the present invention, Figure 4 As shown, the rotating assembly 7 includes a connecting block 71, a movable rod 72, a hinge 73 and a scraper 75.

[0030] During operation, the material enters the storage barrel 1 through the feed pipe 2. At this time, the output shaft of the motor 61 drives the rotating rod 62 and the stirring blade 63 on its surface to rotate counterclockwise to stir the material. In this process, the movable rod 72 is located on the surface of the stirring blade 63. Therefore, during the counterclockwise rotation of the stirring blade 63, the scraper 75 and the stirring blade 63 are The stirring blade 63 moves relative to each other to scrape its surface, and the top view of the stirring blade 63 is elliptical, and the movable rod 72 is located on one side of the rotating rod 62 and is offset therefrom. Therefore, during the rotation of the stirring blade 63, the movable rod 72 will disengage from it and drive the connecting block 71 to rotate downward around the hinge 73 and fall on the surface of the stirring blade 63 again to collide with the stirring blade 63 and generate vibration, thereby reducing the probability of material adhesion on the upper and lower surfaces of the stirring blade 63 and improving the fluidity of the material. Then the movable rod 72 moves relative to the stirring blade 63 again, and uses the scraper 75 on its surface to scrape the surface of the stirring blade 63. In this process, since the stirring blade 63 is spiral, the movable rod 72 drives the connecting block 71 to rotate around the hinge 73, and the evenly stirred material flows into the interior of the mold through the casting tube 3, and then is compression molded.

[0031] As an embodiment of the present invention, Figure 4 As shown, the cross section of the connecting block 71 is a right-angled trapezoid. In the natural state, the inclined surface of the connecting block 71 is tightly fitted with the inner surface of the storage barrel 1. A rotating groove 74 is provided on the side where the outer surface of the connecting block 71 is connected to the movable rod 72.

At the same time, a plurality of groups of teeth 76 are fixedly connected to the upper end outer surface of the stirring blade 63 at a position close to the edge on one side thereof, and mesh with the scraper 75. The movable rod 72 is rotatably connected to the connecting block 71. Therefore, during the rotation of the stirring blade 63, the movable rod 72 moves relative to the surface of the stirring blade 63 and rotates. This can improve the scraping effect of the scraper 75 while stirring the material, thereby improving the mixing effect of the material.

[0033] As an embodiment of the present invention, Figure 4As shown, a mounting groove 77 is provided at the connection between the inner surface of the material storage barrel 1 and the connecting block 71, and an arc-shaped spring piece 78 is fixedly connected to the inner surface of the mounting groove 77.

Therefore, by setting the arc-shaped spring piece 78, the force of the collision between the connecting block 71 and the inner wall of the storage barrel 1 can be effectively reduced, and the arc-shaped spring piece 78 is used to squeeze and rebound to increase the vibration frequency of the movable rod 72, thereby ensuring the service life of the connecting block 71 and the scraping and stirring effect of the movable rod 72.

[0036] By opening a heating chamber 79 inside the movable rod 72, the material can be heated in the process of the movable rod 72 rotating and driving the scraper 75 to scrape the surface of the stirring blade 63, thereby reducing the probability of the material adhering to the movable rod 72 and the scraper rod surface, improving the fluidity of the material, and thus ensuring the casting effect of the device.

[0037] Working principle: During operation, the material enters the interior of the storage barrel 1 through the feed pipe 2. At this time, the output shaft of the motor 61 drives the rotating rod 62 and the stirring blade 63 on its surface to rotate counterclockwise to stir the material, and in this process, the movable rod 72 is located on the surface of the stirring blade 63. Therefore, during the counterclockwise rotation of the stirring blade 63, the scraper 75 moves relative to the stirring blade 63 to scrape its surface, and the top view of the stirring blade 63 is elliptical, and the movable rod 72 is located on one side of the rotating rod 62 and is offset therefrom. Therefore, during the rotation of the stirring blade 63, the movable rod 72 will move with the stirring blade 63. It disengages and drives the connecting block 71 to rotate downward around the hinge 73 and falls on the surface of the stirring blade 63 again to collide with the stirring blade 63 to generate vibration, thereby reducing the probability of material adhesion on the upper and lower surfaces of the stirring blade 63 and improving the fluidity of the material. Then the movable rod 72 moves relative to the stirring blade 63 again, and uses the scraper 75 on its surface to scrape the surface of the stirring blade 63. In this process, since the stirring blade 63 is spiral, the movable rod 72 drives the connecting block 71 to rotate around the hinge 73, and the evenly stirred material flows into the interior of the mold through the pouring pipe 3, and then is subjected to compression molding.

[0038] During the counterclockwise rotation of the stirring blade 63, the scraper 75 moves relative to the stirring blade 63 to scrape its surface. At the same time, a plurality of groups of teeth 76 are fixedly connected to the upper end outer surface of the stirring blade 63 at a position close to the edge on the high side and mesh with the scraper 75, and the movable rod 72 is rotatably connected to the connecting block 71. Therefore, during the rotation of the stirring blade 63, the movable rod 72 moves relative to the surface of the stirring blade 63 and rotates, thereby improving the scraping effect of the scraper 75 while stirring the material, thereby improving the mixing effect of the material.
