Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of wooden molds, and in particular to a sanding mechanism for wooden molds. Background Technology
[0002] In industrial production, wooden molds serve as a crucial foundation for processes such as casting, and their quality directly impacts the final product's quality. As the manufacturing industry continuously pursues product refinement and high performance, the standards for the precision and surface quality of wooden molds are becoming increasingly stringent. In casting production, the model used for molding and core making is called a wooden pattern, also known as a wooden mold. Wooden molds are typically used to form large components. After the sheet metal is cut, its end faces are uneven, requiring grinding machines to polish them. Current grinding machines struggle to flexibly adjust their position and angle for different grinding requirements. Operators often need to spend considerable time and effort manually adjusting the position and angle of the sheet metal during the grinding process, resulting in low work efficiency and difficulty in ensuring product quality. Summary of the Invention
[0003] In view of this, the purpose of this utility model is to overcome the shortcomings of the prior art and provide a sanding mechanism for wooden molds.
[0004] This utility model provides a sanding mechanism for wood molds, including a frame 1. Support frames 4 and grinding discs 3 are symmetrically arranged on the frame 1. A rotating shaft is connected to the center of the two grinding discs 3. A motor 2 is arranged at the bottom of the frame 1. Pulleys are keyed to the output shaft of the motor 2 and the rotating shaft. The two pulleys are connected by a belt. A flat plate 5 is flexibly arranged on the support frame 4. A feeding plate 6 is rotatably arranged above the flat plate 5 near the grinding discs 3.
[0005] Furthermore, a screw block is provided at the bottom of the plate 5, and a screw rod 7 is rotatably provided on the support frame 4 and screwed to the screw block. A guide rod that slides on the support frame 4 is provided laterally on the side of the screw block away from the grinding disc.
[0006] Furthermore, fixing blocks 8 are symmetrically arranged on the front and rear sides of the upper end of the plate 5, and adjusting discs 9 and rotating discs that rotate on the fixing blocks 8 are respectively arranged on the front and rear sides of the bottom of the feeding plate 6. The adjusting discs 9 are locked to the fixing blocks 8 by locking bolts.
[0007] Furthermore, the bottom of the support frame 4 is provided with a chip collection hopper 10 with an open top, and the bottom of the chip collection hopper 10 is provided with a chip discharge hole.
[0008] Furthermore, the side wall of the frame 1 is provided with a storage box 11 located below the chip collection hopper.
[0009] Furthermore, both support frames 4 are provided with arched protective covers 12.
[0010] The advantages of this utility model are as follows: the flat plate and the feeding plate on it can be adjusted left and right on the support frame, and the feeding plate can be rotated and adjusted on the flat plate to adapt to different sanding requirements; the screw drives the screw block and the flat plate to move laterally, and the guide rod can provide precise guidance for the left and right adjustment of the flat plate to prevent the flat plate from shifting or shaking during the adjustment process; the locking bolt passes through the adjustment hole and is screwed to the fixing block. After loosening the locking bolt, the flat plate can be rotated to adjust the angle, and then the locking bolt is tightened to lock the adjustment plate; the sawdust produced by sanding falls into the sawdust hopper and comes out from the sawdust outlet hole, and the sawdust falls into the storage box; the protective cover covers the rotating shaft and belt to prevent debris from being caught or people from being injured.

[0016] The present invention will now be described in detail with reference to the accompanying drawings.
[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.
[0018] See Figures 1 to 5This utility model provides a sanding mechanism for wood molds, comprising a frame 1, on which support frames 4 and grinding discs 3 are symmetrically arranged. A rotating shaft is connected to the center of the two grinding discs 3, and the rotating shaft rotates on the frame. A motor 2 is located at the bottom of the frame 1. Pulleys are keyed to the output shaft and rotating shaft of the motor 2, and the two pulleys are connected by a belt. A flat plate 5 is flexibly and horizontally arranged on the support frame 4, and the flat plate is placed horizontally and close to the support frame. A screw block is located at the bottom of the flat plate 5. A screw rod 7, which is screwed to the screw block, is rotatably arranged on the support frame 4. A guide rod, which is slidably fitted onto the support frame 4 on the side of the screw block away from the grinding discs, is screwed onto the support frame. Tightening the locking bolts of the guide rod prevents the screw from rotating on its own. The screw drives the screw block and plate to move laterally. The guide rod provides precise guidance for the left and right adjustment of the plate, preventing the plate from shifting or shaking during the adjustment process, and ensuring the accuracy and stability of the plate adjustment. Above the plate 5, a feeding plate 6 is rotatably adjustable near the grinding disc 3. The plate can be adjusted left and right on the support frame, and its position can be flexibly adjusted according to different sizes of wooden molds and sanding requirements. The feeding plate can be rotated and adjusted above the plate, eliminating the need for manual adjustment of the board. This allows operators to place the board at the appropriate angle for sanding, better meeting the sanding requirements of different shapes and parts.
[0019] Fixed blocks 8 are symmetrically arranged on the front and rear sides of the upper end of the plate 5. Adjusting discs 9 and rotating discs that rotate on the fixed blocks 8 are respectively arranged on the front and rear sides of the bottom of the feeding plate 6. The adjusting discs 9 are locked to the fixed blocks 8 by locking bolts. The adjusting discs are provided with arc-shaped adjusting holes. The locking bolts pass through the adjusting holes and are screwed to the fixed blocks. After loosening the locking bolts, the plate can be rotated to adjust the angle. Then, the locking bolts are tightened to lock the adjusting discs.
[0020] See Figure 1 The support frame 4 has a chip hopper 10 with an open top at the bottom, and a chip outlet at the bottom of the chip hopper 10. The chip hopper is a right-angled triangle, and the wood chips produced by sanding fall into the chip hopper and come out from the chip outlet.
[0021] A storage box 11 is provided on the side wall of the frame 1, located below the chip collection hopper. Wood chips in the chip collection hopper fall into the storage box through the chip outlet. The storage box is magnetically attached to the side wall of the frame, making it easy to install and remove. The magnets are located on the front and back sides of the outer wall of the storage box.
[0022] The two support frames 4 are equipped with arched protective covers 12. The protective covers cover the rotating shaft and belt to prevent debris from getting caught or people from being injured.
[0023] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
