Description

Technical Field

[0001] The utility model relates to the technical field of saw cutting, in particular to a casting sand mold cutting device. Background Art

[0002] The supercharger housing is cast using a pre-cast sand mold. The quality of the sand mold affects the production quality of the product. During the production process, the sand mold may have redundant parts, which require the use of a cutting device to cut to ensure that the overall shape meets the requirements. A saw is generally used for cutting.

[0003] Conventional saw cutting devices use a reciprocating mechanism to drive a saw blade in reciprocating motion, cutting the sand mold that moves toward and abuts it. However, the saw blades in these devices are often very long, covering a wide cutting range. However, most conventional saw blades lack a retaining structure. During the actual cutting process, the contact between the saw blade and the sand mold can cause forces in non-reciprocating directions, causing the saw blade to vibrate, affecting the cutting effect and, in severe cases, even breaking the blade. Even with retaining structures in some devices, these structures cannot be moved or adjusted, and their position cannot be adjusted based on the size of the cutting range, failing to achieve optimal retaining effects.

The sliders 3 are provided with threaded holes and are screwed to the threaded rods 8 through the threaded holes.

[0018] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process, which are as follows:

[0019] According to the instruction manual Figure 1-3It can be seen that when the present invention is working, the frame plate 2 is fixedly set for installing the entire device. The reciprocating motion mechanism 14 is a prior art that can achieve the purpose of driving the drive rod 13 and the saw blade 12 to move back and forth horizontally to drive cutting. The present invention only describes the cutting position of the saw blade 12, and does not describe the fixed and moving parts of the casting sand mold. By using the prior art, the material fixing and moving functions can be achieved. The reciprocating motion mechanism 14 drives the drive rod 13 and the saw blade 12 to move back and forth horizontally. The drive rod 13 remains stable under the limiting action of the limiting slide 1. A cross plate 7 is provided at the bottom of the frame plate 2 through the connecting plate 5. A driving moving assembly is provided at the bottom of the cross plate 7. A limiting assembly is provided on its moving end through the U-shaped frame 9. The limiting assembly can limit the two sides of the saw blade 12 to ensure the stability of the saw blade 12 during cutting, improve the cutting effect, and increase the service life of the saw blade 12. Due to the different sizes of sand molds, the required cutting ranges are different. If the limit assemblies on both sides are too close to each other, it will affect the feeding of the sand mold and cutting cannot be performed. If the limit assemblies on both sides are too far apart, the limiting effect will be poor. Therefore, it is necessary to adjust the positions of the two limit assemblies by driving the moving assembly. Since the driving moving assembly has two moving ends and can move inward or outward at the same time, the moving end is connected to the limit assembly through the U-shaped frame 9, so the purpose of adjusting the position of the limit assembly can be achieved. It is adjusted according to the cutting range to ensure that the limit rollers 11 on both sides of the cutting range are in the optimal limiting position.

[0020] The limiting assembly includes a mounting frame 10 and multiple pairs of limiting rollers 11. The mounting frame 10 is a rectangular frame with its upper surface fixedly connected to the lower end of the U-shaped frame 9. The mounting frame 10 is sleeved on the outside of the saw blade 12. Multiple pairs of limiting rods are vertically arranged between the upper and lower walls of the mounting frame 10 and are respectively positioned on both sides of the saw blade 12. The side surfaces of the limiting rollers 11 abut against the side surfaces of the saw blade 12. During operation, the saw blade 12 moves back and forth horizontally, and the limiting rollers 11 abut against the front and rear side walls of the saw blade 12 to prevent it from shaking in the front and rear directions, ensuring the stability of the saw blade 12 during cutting, improving the cutting effect, and preventing the saw blade 12 from shaking too much and being damaged.

[0021] The limiting roller 11 is provided with a rubber sleeve 15 which is thick in the center and thin at both ends. The center of the rubber sleeve 15 abuts against the center of the saw blade 12 for limiting, thereby ensuring the limiting effect while reducing the wear between the saw blades 12.

[0022] The drive assembly includes a motor 6 with dual outputs, a pair of threaded rods 8 with opposite thread directions, and a pair of sliders 3. A chute 4 is defined at the bottom of the horizontal plate 7. The motor 6 is positioned at the center of the chute 4. One end of the pair of threaded rods 8 is connected to the two output ends of the motor 6, and the other end is rotatably connected to the sidewalls of the chute 4. The pair of sliders 3 are slidably connected to the chute 4 and are located on either side of the center of the chute 4. During operation, the motor 6 drives the pair of threaded rods 8 with opposite thread directions to rotate. Since the sliders 3 are screwed to the threaded rods 8 through threaded holes and slidably connected to the chute 4, they can drive the sliders 3 to move inward or outward simultaneously, driving the synchronous adjustment of the position of the limit assembly, and the adjustment method is simple and convenient.

[0023] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
