[0030] Next, in combination with Figures 1 to 4 , through specific embodiments and their application scenarios, a kind of anti-falling component and dipping device for sand core dipping provided by the embodiments of the present utility model will be described in detail.
[0031] Embodiment 1
[0032] A kind of anti-falling component for sand core dipping, including an anti-falling net bag 3. A plurality of first connecting rods 13 are arranged on the opening edge of the anti-falling net bag 3. A plurality of second connecting rods 5 are arranged on the first connecting rods 13. An auxiliary fixing rod 6 is also arranged on the first connecting rods 13, and the auxiliary fixing rod 6 is located above the second connecting rods 5.
[0033] Specifically, as Figure 2As shown, the anti-drop net bag 3 is welded with four first connecting rods 13 on the edge of the opening, which facilitates the connection of the anti-drop net bag 3 with other components. Two second connecting rods 5 perpendicular to each other are welded on each first connecting rod 13, which are used to connect the anti-drop component 2 to the container filled with paint. An auxiliary fixing rod 6 is also welded on the first connecting rod 13. The auxiliary fixing rod 6 is located above the second connecting rod 5. When the second connecting rod 5 breaks, the auxiliary fixing rod 6 further prevents the anti-drop component 2 from falling directly into the paint, thereby playing an auxiliary support role. The anti-drop component 2 is set during the sand core dipping process to avoid the problem of the sand core falling into the paint and contaminating the paint, which provides great protection for the product quality and personnel operation safety of the sand core dipping process.
[0034] Further, if Figure 2 As shown, the anti-drop net bag 3 is composed of several longitudinally arranged U-shaped strips and several horizontal strips. Several horizontal strips are arranged along the sides of the U-shaped strips. Several U-shaped strips are connected by horizontal strips, and the U-shaped strips are welded to the horizontal strips. Several U-shaped strips are connected by horizontal strips, so that the anti-drop net bag 3 is U-shaped as a whole. A mechanism for stirring the paint is often provided in a container filled with paint to stir the paint evenly. When the anti-drop net bag 3 is placed in a paint container filled with paint, the U-shaped structure can provide a larger stirring space for the stirring mechanism. Among them, the U-shaped strips can be a sheet-like structure or a rod-like structure, and the horizontal strips can also be a sheet-like structure or a rod-like structure. End rods 12 are also welded at both ends of each U-shaped strip, and the anti-drop net bag 3 is welded to the first connecting rod 13 through the end rods 12.
[0035] Further, if Figure 2 As shown, the U-shaped strips at both ends of the anti-drop net bag 3 are provided with three lateral fixing rods. The uppermost one is a boundary rod, which is welded to the end rod 12. The remaining two lateral fixing rods 11 are provided at thirds of the arc length of the U-shaped strip. The lateral fixing rods 11 prevent the anti-drop net bag 3 from deforming and improve the strength of the anti-drop net bag 3.
[0036] Further, if Figure 2 As shown, the first connecting rod 13 is further provided with a secondary rod 4. Preferably, the position of the secondary rod 4 is on the same plane as the auxiliary fixing rod 6, so that the staff can easily install and remove the anti-drop assembly 2 by hand through the secondary rod 4. Preferably, the secondary rod 4 is a round rod, which can effectively prevent the staff from being cut or other accidents during operation.
[0037] Example 2
[0038] A dipping device having an anti-drop assembly for dipping sand cores in Example 1 includes a paint bucket 1, a plurality of mounting blocks 7 are arranged in the paint bucket 1, a second connecting rod 5 is connected to the mounting blocks 7, and a paint stirring mechanism is also provided in the paint bucket 1, and the paint stirring mechanism is located outside the anti-drop assembly 2.
[0039] Specifically, such asFigures 1 to 4 As shown, the bottom of the paint bucket 1 is set to be arc-shaped. Four mounting blocks 7 are welded to the inner wall of the paint bucket 1. Optionally, the mounting blocks 7 are stainless steel sheets. The four mounting blocks 7 are symmetrically arranged. The anti-falling component 2 is placed in the paint bucket 1 by overlapping with the mounting blocks 7 through the second connecting rod 5. A paint stirring mechanism is arranged inside the paint bucket 1 to stir the paint evenly to ensure the dipping effect of the sand core. The setting of the position of the mounting blocks 7 ensures that the anti-falling component 2 does not contact the paint stirring mechanism, leaving a stirring space for the paint stirring mechanism.
[0040] Furthermore, a groove is provided on the mounting block 7, and the second connecting rod 5 is located in the groove. Among them, the depth of the groove is 1 / 3 to 1 / 2 of the height of the second connecting rod 5. The shape of the groove is adapted to the second connecting rod 5. The second connecting rod 5 is placed through the groove, so that the anti-falling component 2 is placed in the paint bucket 1, and at the same time, a stirring space is left for the paint stirring mechanism. A second connecting rod 5 perpendicular to each other is welded on the first connecting rod 13 of the anti-falling component 2. When one of the second connecting rods 5 is placed in the groove, the side of the other second connecting rod 5 can be abutted against the side of the mounting block 7 to prevent the anti-falling component 2 from shaking in the direction parallel to the length of the groove.
[0041] Furthermore, as Figure 1 shown, the auxiliary fixing rod 6 is located above the edge of the bucket mouth of the paint bucket 1, and the end of the auxiliary fixing rod 6 extends beyond the inner edge of the bucket mouth of the paint bucket 1. The auxiliary fixing rod 6 ensures that when the mounting block 7 is damaged, after the anti-falling component 2 falls, the auxiliary fixing rod 6 can be abutted against the bucket mouth of the paint bucket 1 to prevent the anti-falling component 2 from directly falling into the paint bucket 1.
[0042] Furthermore, as Figure 1 、 Figure 3 and Figure 4 shown, the paint stirring mechanism includes a stirring vertical rod 8, a stirring cross rod 9 and a driving mechanism 14 connected to the paint bucket 1. The driving mechanism 14 is fixedly connected to the upper edge of the paint bucket 1. One end of the stirring vertical rod 8 is connected to the driving mechanism 14, and the other end of the stirring vertical rod 8 is connected to the stirring cross rod 9. The stirring vertical rod 8 is arranged close to the inner wall of the paint bucket 1, and the stirring cross rod 9 is arranged close to the bottom of the paint bucket 1. A reciprocating swing motor is arranged inside the driving mechanism 14. The driving mechanism 14 is fixed on the upper edge of the paint bucket 1 through a bracket. The output end of the reciprocating swing motor is fixedly connected to one end of the stirring vertical rod 8, so that the stirring vertical rod 8 realizes reciprocating swing, and further drives the stirring cross rod 9 to realize reciprocating swing below the anti-falling component 2, avoiding poor phenomena such as precipitation, stratification or curing of the paint during storage and use, thereby affecting the dipping effect and the quality of the sand core.
[0043] Furthermore, one stirring blade 10 is fixedly connected to each of the two vertical stirring rods 8, and four stirring blades 10 are fixedly connected to the stirring cross bar 9. Among them, the stirring blade 10 is an arc-shaped blade, and the arc surfaces of the four stirring blades 10 on the stirring cross bar 9 are arranged in a staggered manner in the front and back. The position of the stirring blade 10 does not contact the anti-falling component 2 during operation. By setting the stirring blade 10 into an arc shape, the stirring area of the stirring blade 10 is increased, and the coating stirring efficiency is improved.
[0044] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
