Description

Technical Field

[0001] This utility model relates to the field of surface treatment equipment technology, and in particular to a multi-station mold sandblasting device with adjustable nozzle angle. Background Technology

[0002] In the field of mold manufacturing and processing, sandblasting is a crucial process. It can effectively clean impurities and oxide scale from the mold surface, improve the surface roughness, and enhance the appearance quality and service life of the mold. Traditional mold sandblasting usually uses a single-station sandblasting device with a fixed nozzle angle. When this device is working, the mold is placed in a fixed position, and the nozzle sprays sand onto the mold surface at a fixed angle.

[0003] Currently, traditional sandblasting equipment in mold sandblasting operations often has some limitations. For example, many devices adopt a single-station design, where mold clamping, sandblasting, and unloading can only be performed sequentially. The equipment is idle during non-sandblasting periods, resulting in low overall processing efficiency. At the same time, the spray angle of the sandblasting head is mostly fixed, making it difficult to quickly and accurately adapt to the sandblasting requirements of molds with different contours, affecting the uniformity and effect of processing. In addition, the waste sand generated during the sandblasting process is often inconvenient to collect, easily causing dust pollution in the working environment, and poor sealing may lead to sand leakage, posing safety hazards and hindering the recycling of sand. Operators also find it difficult to visually monitor the sandblasting process inside the chamber without interrupting operations, causing inconvenience to process control and equipment maintenance. Therefore, it is necessary to design a multi-station mold sandblasting device with adjustable nozzle angle to solve the above problems. Utility Model Content

Detailed Implementation

[0021] Example: A multi-station mold sandblasting device with adjustable nozzle angle, such as... Figures 1-5As shown, the system includes a support frame 1, a sandblasting chamber 2, a storage bin 3, a feed pipe 4, a motor 5, a rotating column 6, a gear 7, a fixing pad 8, a workstation turntable 9, a fixing plate 10, a support column 11, a worm gear 12, a worm 13, a sliding block 14, a handwheel 15, a sandblaster 16, a lower sand hopper 17, a connecting pipe 18, a pulley 19, and a rubber belt 20. The sandblasting chamber 2 is welded to the top of the support frame 1. The sandblasting chamber 2 is made of wear-resistant and corrosion-resistant material, and its bottom is lower at the front and higher at the back. The storage bin 3 is bolted to the rear top of the sandblasting chamber 2. A feed pipe 4 is threaded onto the top right side of the material bin 3. A motor 5 is bolted to the bottom right side of the support frame 1. A rotating column 6 is keyed to the output shaft of the motor 5. A gear 7 is connected to the middle of the rotating column 6 via a keyway. Three fixing pads 8 are installed in a straight array from the motor 5 along the left side of the bottom of the support frame 1. Each of the three fixing pads 8 is rotatably connected to a rotating column 6, and each rotating column 6 is connected to a gear 7 via a keyway. All four gears 7 are on the same horizontal line and mesh with each other. The upper ends of the four rotating columns 6 pass through the top of the sandblasting chamber 2. Each of the four rotating columns 6 is equipped with a workstation turntable 9, which is located inside the sandblasting chamber 2. A fixing plate 10 is bolted to the top of each rotating column 6. Each of the four fixing plates 10 corresponds to one of the four workstation turntables 9. A support column 11 is welded to the bottom of each of the four fixing plates 10. A worm gear 12 is fitted into the middle of each of the four support columns 11, and a corresponding worm 13 is fitted below the worm gear 12. The worm 13 extends forward to the outside of the sandblasting chamber 2. Both ends of the bottom of each of the four support columns 11 are slidably connected to both ends of the top of the sliding block 14. Next, a handwheel 15 is welded to the front end of the leftmost worm 13. Sandblasters 16 are installed at the bottom of each of the four sliding blocks 14. The top of the sandblasting chamber 2 is connected to the lower sand hopper 17 by bolts at the rear side of each fixed plate 10. All four lower sand hoppers 17 are connected to the storage box 3. A connecting pipe 18 connects the bottom of each lower sand hopper 17 to the top of each sandblaster 16. Pulleys 19 are fitted on the body of each worm 13, and the pulleys 19 of adjacent worms 13 are connected by rubber belts 20, thereby realizing the synchronous rotation of the four worms 13.

[0022] When this device is needed, the mold to be sandblasted is first placed on the workstation turntable 9. This device has four workstation turntables 9. After the motor 5 is started, its output shaft drives the rotating column 6 fixedly connected to it to rotate. The gear 7 in the middle of the rotating column 6 rotates accordingly. Since the gears 7 on each rotating column 6 are on the same horizontal line and mesh with each other, the rotation of one gear 7 will drive the other gears 7 to rotate synchronously, thereby making the four rotating columns 6 rotate synchronously and the four workstation turntables 9 rotate synchronously, realizing the conversion of the mold between different workstations. The storage box 3 is connected to the four sand hoppers 17. The sand will flow from the storage box 3 into the sand hoppers 17. The bottom of the sand hoppers 17 is connected to the top of the sandblaster 16 through the connecting pipe 18. The sand enters the sandblaster 16 through the connecting pipe 18. The four sandblasters 16 are respectively fixed to the bottom of the four sliding blocks 14, which can perform sandblasting operations on the mold on the workstation turntable 9.

[0023] When the angle of the sandblaster 16 needs to be adjusted, turn the handwheel 15 to rotate the worm 13. Since the pulley 19 between each pair of worms 13 is fitted with a rubber belt 20, the rotation of one worm 13 will drive the other worms 13 to rotate synchronously through the pulley 19 and the rubber belt 20. When the worm 13 rotates, it meshes with the worm wheel 12. The rotation of the worm will drive the sliding block 14 connected to it to slide back and forth on the support column 11, thereby realizing the adjustment of the angle of the sandblaster 16 to meet the sandblasting requirements of different molds.

[0024] like Figure 5 As shown, it also includes a sealing plate 21, a first fixing block 22, a second fixing block 23, a connecting rod 24, a torsion spring 25, and an observation window 30. The sealing plate 21 is provided on the rear side of the sandblasting chamber 2. The first fixing blocks 22 are welded to the left and right sides of the upper rear part of the sandblasting chamber 2. The second fixing blocks 23 are welded to the left and right sides of the top of the sealing plate 21. The first fixing blocks 22 and the second fixing blocks 23 are located on the same horizontal line. The connecting rod 24 is welded between the two first fixing blocks 22 and is rotatably connected to the two second fixing blocks 23. The torsion spring 25 is provided between the first fixing blocks 22 and the second fixing blocks 23. The observation windows 30 are installed on the left and right sides of the sandblasting chamber 2. The observation windows 30 are made of wear-resistant transparent material.

[0025] During the sandblasting operation, in order to ensure the airtightness of the sandblasting chamber 2, a sealing plate 21 is installed at the rear of the sandblasting chamber 2. The sealing plate 21 is connected to the sandblasting chamber 2 through a first fixing block 22, a second fixing block 23, a connecting rod 24 and a torsion spring 25. When the sealing plate 21 is opened to put in or take out the mold, the torsion spring 25 will cause the sealing plate 21 to automatically reset and close, preventing sand leakage. During the operation, the operator can also observe the sandblasting situation inside the sandblasting chamber 2 in real time through the observation window 30. The observation window 30 is made of wear-resistant and transparent material, which can withstand the impact of sand without affecting the observation effect. At the same time, the sandblasting chamber 2 is made of wear-resistant and corrosion-resistant material, which can effectively extend the service life of the device.

[0026] like Figure 1 and Figure 6 As shown, it also includes a recycling bin 26, a sand collecting plate 27, a sand discharge valve 28, and an opening and closing door 29. The recycling bin 26 is bolted to the front side of the support frame 1. The front side of the support frame 1 has a rectangular slot, and the sand collecting plate 27 is bolted to the corresponding slot. The upper part of the sand collecting plate 27 is rectangular and the lower part is trapezoidal. The lower part of the sand collecting plate 27 is connected to the recycling bin 26. The sand discharge valve 28 is threaded to the bottom front side of the recycling bin 26. The opening and closing door 29 is rotatably connected to the right side of the support frame 1.

[0027] After the sandblasting operation is completed, the motor 5 is turned off and the sandblaster 16 is reset. The waste sand generated by the sandblasting operation will fall to the bottom of the sandblasting chamber 2. Since the bottom of the sandblasting chamber 2 is designed to be lower in the front and higher in the back, the waste sand will naturally flow forward. The waste sand will flow into the recovery box 26 through the sand collection plate 27. The upper part of the sand collection plate 27 is rectangular and the lower part is trapezoidal, which is conducive to the collection and flow of waste sand. The bottom front side of the recovery box 26 is fixedly connected to the sand discharge valve 28. When the waste sand in the recovery box 26 accumulates to a certain level, the sand discharge valve 28 can be opened to discharge the waste sand, realizing the centralized collection and treatment of waste sand. The rotating opening and closing door 29 on the right side of the support frame 1 facilitates the operator to maintain and repair the motor 5, gear 7 and other components inside the device.
