Description

Technical Field

[0001] The utility model relates to the technical field of mold maintenance, in particular to a mold sandblasting machine that is easy to use. Background Art

[0002] Molds are various molds and tools used in industrial production to produce desired products through methods such as injection molding, blow molding, extrusion, die-casting, forging, smelting, and stamping. Simply put, molds are tools used to create shaped objects. These tools are composed of various parts, and different molds are made up of different parts. They primarily achieve the desired shape by changing the physical state of the material being molded. After long-term use, molds can develop rust and corrosion on their surfaces. Mold sandblasting is a method of cleaning the mold surface by spraying sand particles at high speed. A sandblaster uses compressed air to spray sand onto the mold surface. The high-speed impact and friction of the sand particles remove impurities such as oxides, rust, and oil from the mold surface, thereby improving the quality and precision of the mold surface.

[0003] At present, the existing mold sandblasting machine is not equipped with auxiliary mechanisms. Therefore, when the operator holds the spray gun for a long time to sandblast the mold, it is easy to cause the operator's hand muscles to fatigue and hand tremors, resulting in uneven sandblasting, which not only reduces the sandblasting effect, but also reduces the operator's usage experience. At the same time, there is no adjustable workbench installed, and the other hand needs to hold the mold for a long time to sandblast, which greatly increases the operator's workload and reduces the convenience of use and sandblasting experience. Summary of the Invention

A spherical groove b is hollowed out on the inner wall of the top of the operating chamber, and the spherical groove b is movably connected to the spherical joint b. The maximum diameter of the annular groove b is smaller than the maximum diameter of the spherical joint b.

[0006] According to the above technical solution, the hand holding the gun for sandblasting can be lifted by an auxiliary mechanism to avoid hand fatigue caused by holding the spray gun for a long time, uneven spraying, and reduced operator experience. At the same time, the mold can be placed on the workbench for sandblasting through the adjustable workbench, avoiding the need for the other hand to hold the mold for sandblasting, which greatly improves the comfort of use.

[0009] Furthermore, the auxiliary mechanism is arranged on the glove on the side close to the spray gun.

[0010] According to the above technical solution, the auxiliary mechanism is located on the side of the spray gun, which improves the convenience of holding the spray gun and reduces the fatigue of the hand muscles.

Specific implementation method

[0025] See also Figure 1-9 The present embodiment is a mold sandblasting machine that is easy to use and is constructed of an operating chamber 1 and a sand bucket. Two gloves 2 are provided on the surface of the operating chamber 1 and extend into the interior of the operating chamber 1. A spray gun 3 for mold sandblasting is provided inside the operating chamber 1. A workbench 4 is provided inside the operating chamber 1. The workbench 4 is used to place the mold. There is a gap between the bottom of the workbench 4 and the bottom of the operating chamber 1. The surface of the workbench 4 is wrapped with a bearing 5 so that the workbench 4 can rotate. A connecting rod 6 is welded to one end of the bearing 5. The connecting rod 6 is connected to a driving mechanism. When the driving mechanism is working, the workbench 4 is raised and lowered. An auxiliary mechanism is installed on the surface of the glove 2. The auxiliary mechanism is used to lift the arm holding the gun, which reduces the fatigue of holding the gun for sandblasting for a long time. The auxiliary mechanism includes a fixing ring 7, which is fixedly mounted on the surface of the glove 2. The installation position is located at the forearm, avoiding the hand joint. The surface of the fixing ring 7 is hollowed out with an annular groove. 8. A slider 9 is rotatably connected in the annular groove 8. The slider 9 is arc-shaped and matches the annular groove 8. A spherical groove a10 is hollowed out on the surface of the slider 9. A spherical joint a11 is movably connected in the spherical groove a10. The spherical joint a11 can be universally rotated in the spherical groove a10. The maximum diameter of the annular groove 8a is smaller than the maximum diameter of the spherical joint a11. Therefore, when the spherical joint a11 is embedded in the annular groove 8a, it can be rotated without falling off. A first movable rod 12 is integrally formed at the top of the spherical joint a11. The other end of the first movable rod 12 is movably connected to the second movable rod 13. The other end of the second movable rod 13 is integrally formed with a spherical joint b14. A spherical groove b15 is hollowed out on the inner wall of the top of the operating chamber 1. The spherical groove b15 is movably connected to the spherical joint b14. The maximum diameter of the annular groove 8b is smaller than the maximum diameter of the spherical joint b14.

[0026] Furthermore, the driving mechanism includes a mounting cover 16, the interior of the mounting cover 16 is hollow, a motor 17 is fixed to the top of the interior of the mounting cover 16, the output end of the motor 17 is connected to the screw rod 18, the connecting rod 6 is threadedly connected to the screw rod 18 at one end away from the bearing 5, and a slide groove 19 is provided on one side of the mounting cover 16. The slide groove 19 connects the operating chamber 1 with the internal cavity of the mounting cover 16, and the connecting rod 6 extends through the slide groove 19 to the interior of the operating chamber 1 at one end away from the screw rod 18 and is welded to the bearing 5 inside the operating chamber 1, thereby driving the workbench 4 to rise and fall.

[0027] Furthermore, the auxiliary mechanism is provided on the glove 2 on the side close to the spray gun 3 to facilitate the operation of the operator.

[0028] Furthermore, a switch 20 is provided on the inner wall of the operating compartment 1 . The switch 20 is used to control the operation of the motor 17 , and the switch 20 is electrically connected to the motor 17 .

[0029] The working principle of this embodiment is as follows: when in use, the mold is placed on the workbench 4, and both hands are put through the gloves 2 to the inside of the operating chamber 1 for sandblasting. The mold on the workbench 4 can be sandblasted by holding the spray gun 3 through the gloves 2 equipped with an auxiliary mechanism. Since the gun-holding hand lifts and pulls through the auxiliary mechanism, and the angle can be adjusted through the ball joint a11 and the ball joint b14, when the forearm is bent, the first movable rod 12 and the second movable rod 13 are bent, which improves the convenience of use. At the same time, the slider 9 can be moved in the annular groove 8 to achieve the hand flipping and rotation to adjust the angle, which improves the flexibility of the auxiliary mechanism. At the same time, when sandblasting for a long time, the lifting of the auxiliary mechanism reduces the gravity of the hand and reduces fatigue, thereby improving the uniformity of sandblasting and the user experience. At the same time, the other hand can rotate the workbench 4 to rotate the mold to achieve multi-angle sandblasting. When the mold needs to be lifted or lowered, the control switch 20 can be used to make the motor 17 rotate forward and reverse to make the screw 18 rotate, so that its connecting rod 6 performs vertical lifting and lowering movements on its surface, thereby improving the comfort of operation, avoiding the need for the operator to hold the mold for sandblasting, and reducing the work intensity.
