Description

Technical Field

[0001] This utility model relates to the field of mold surface treatment technology, specifically to a rotational molding mold surface treatment device. Background Technology

[0002] Chinese utility model patent CN202420907508.9 discloses a surface treatment device for rotational molding molds, including a heating chamber and a door. The door is hinged to the front side of the heating chamber. Heating wires are arranged on the inner side wall of the heating chamber. A fixing ring is fixedly connected inside the heating chamber. A detachable placement rack is installed on the top of the fixing ring for placing the mold. The device also includes a steam injection assembly mounted on the heating chamber. The output end of the steam injection assembly extends into the interior of the heating chamber and is located below the fixing ring. The steam injection assembly removes residues from the mold surface by spraying steam onto the mold. A drive mechanism is also mounted on the heating chamber. In this utility model, a motor drives a cam to rotate, which in turn drives the placement ring to reciprocate up and down. This causes the placement ring to cause the mold to oscillate up and down. Under the action of inertia, the residues inside the mold are dislodged, resulting in a cleaner mold.

[0003] However, when the placement rack vibrates, the mold is not limited on the placement rack. As the placement rack vibrates, it will be shaken up and down. Although it can vibrate out the impurities inside, it will cause damage to the edge of the mold and affect the quality of the mold.

[0004] To address the aforementioned issues, we propose an improvement: a surface treatment device for rotational molding dies. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] This utility model provides a surface treatment device for rotational molding mold, including a heating box and a mold.

[0008] A steam generator is installed on the outside of the heating box, and a main pipe is installed inside the heating box. Several L-shaped branch pipes are connected to both sides of the main pipe. The top of the branch pipes is threaded with a cap, and several annular grooves are passed through the top of the cap.

[0009] As a preferred technical solution of this utility model, the guide rod is rotatably connected to the interior of the heating box, and the guide rod is provided with two sets of threaded grooves. The same set of threaded grooves is divided into a first threaded groove and a second threaded groove, and the thread directions of the first threaded groove and the second threaded groove are opposite.

[0010] As a preferred technical solution of this utility model, the bottom of the active component and the passive component are respectively equipped with sliders. The sliders of the active component and the passive component of the same group of moving components are respectively threadedly connected to the first threaded groove and the second threaded groove. The sliders at the bottom of the same group of moving components move in opposite directions. A first servo motor is installed on the outside of the heating box. The rotation shaft of the first servo motor is coaxially and fixedly connected to the guide rod.

[0011] As a preferred technical solution of this utility model, the other ends of several springs are respectively fixedly connected to the inner surface of the moving part, a second servo motor is installed on the outer top surface of the active part, the output shaft of the second servo motor is fixedly connected to the cam coaxially, and a through groove is opened on the side wall of the active part near the cam.

[0012] As a preferred technical solution of this utility model, the top of the active component and the passive component are respectively provided with a sliding groove, the top of the several support frames are respectively slidably connected to the top of the moving component through the sliding groove, the bottom of the support frame is fixedly connected to the push plate, the limiting component is fixedly installed on the top of the support frame, and the lower edge of the mold is placed on the support frame.

This rotational molding mold surface treatment device adjusts the position between two sets of moving parts by rotating the guide rod until the lower edges of both sides of the mold are respectively engaged with the limiting parts, so that the device can adapt to the processing of molds of different sizes.

[0017] 2. When the cam rotates, it pushes the push plate to the side. When the push plate is under force, the spring is compressed. The cam rotates in a cycle and pushes the push plate repeatedly, causing the push plate to drive the clamping parts above it to vibrate left and right. During the vibration, the limiting parts clamp the mold, so that the mold is protected from the impact of the vibration and avoids the surface treatment process from affecting the quality of the mold.

[0027] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0028] Example: Figure 1-7 As shown, a rotational molding die surface treatment device includes a heating box 1 and a die 2. The heating box 1 is characterized by having a slide rail 4 and a guide rod 11 connected inside. The slide rail 4 and the guide rod 11 are provided with two sets of moving parts 3. The upper part of the moving parts 3 is provided with several support frames 5 and limiting parts 12.

[0029] The moving part 3 is divided into an active part 301 and a passive part 302. Push plates 16 are slidably installed inside the active part 301 and the passive part 302 respectively. Several springs 17 are connected to one side of the push plate 16. A cam 14 is provided inside the active part 301.

[0030] A steam generator 8 is installed on the outside of the heating box 1, and a main pipe 10 is installed inside the heating box 1. Several L-shaped branch pipes 20 are connected to both sides of the main pipe 10. The top of the branch pipes 20 is threaded with a top cap 21, and several annular grooves 22 are passed through the top of the top cap 21.

[0031] The guide rod 11 is rotatably connected to the interior of the heating box 1. Two sets of threaded grooves 19 are provided on the guide rod 11. The same set of threaded grooves 19 is divided into a first threaded groove 1901 and a second threaded groove 1902. The thread directions of the first threaded groove 1901 and the second threaded groove 1902 are opposite.

[0032] The bottom of the active component 301 and the passive component 302 are respectively equipped with sliders 18. The sliders 18 of the active component 301 and the passive component 302 of the same group of moving components 3 are respectively threaded to the first thread groove 1901 and the second thread groove 1902. The sliders 18 at the bottom of the same group of moving components 3 move in opposite directions. The heating box 1 is equipped with a first servo motor 7. The rotation shaft of the first servo motor 7 is coaxially fixedly connected to the guide rod 11.

[0033] The first servo motor 7 drives the guide rod 11 to rotate, causing the active part 301 and the passive part 302 of the same set of moving parts 3 to move in opposite directions. After adjusting the distance between the active part 301 and the passive part 302, the lower edge of the mold 2 is locked onto the limiting part 12.

[0034] The other ends of several springs 17 are fixedly connected to the inner surface of the moving part 3, and a second servo motor 9 is installed on the outer top surface of the active part 301. The output shaft of the second servo motor 9 is fixedly connected to the cam 14 on the same axis. A through groove 15 is provided on the side wall of the active part 301 near the cam 14.

[0035] The top of the active component 301 and the passive component 302 are respectively provided with a sliding groove 13. The top of several support frames 5 are slidably connected to the top of the moving component 3 through the sliding groove 13. The bottom of the support frame 5 is fixedly connected to the push plate 16. The limiting component 12 is fixedly installed on the top of the support frame 5. The lower edge of the mold 2 is placed on the support frame 5.

[0036] The second servo motor 9 drives the cam 14 to rotate, causing the cam 14 to repeatedly push the push plate 16. When the push plate 16 moves, it squeezes the spring 17. After the pushing force disappears, the spring 17 returns to its original position. This process enables the push plate 16 to drive the limiting member 12 to vibrate left and right, shaking out impurities inside the mold 2. During this process, the limiting member 12 always clamps the edge of the mold 2 to avoid vibration damage to the mold.

[0037] Several branch pipes 20 are connected to the main pipe 10. The top of the branch pipe 20 passes upward through the gap between the slide rail 4 and the guide rod 11. The main pipe 10 is connected to the steam generator 8. The steam generated by the steam generator 8 heats the bottom of the mold from each branch pipe 20 upward. Impurities falling inside the mold 2 are blocked by the top cap 21 and will not fall into the pipe below. The annular groove 22 can be cleaned by periodically unscrewing the top cap 21.

[0038] A guide plate 6 is installed at an angle on the bottom of the heating box 1. Excess impurities fall onto the guide plate 6 and slide outwards with its angle.

[0039] Working principle: In use, the first servo motor 7 drives the guide rod 11 to rotate, causing the active part 301 and the passive part 302 of the same set of moving parts 3 to move in opposite directions. After adjusting the distance between the active part 301 and the passive part 302, the lower edge of the mold 2 is locked onto the limiting part 12. The second servo motor 9 drives the cam 14 to rotate, causing the cam 14 to repeatedly push the push plate 16. When the push plate 16 moves, it squeezes the spring 17. After the pushing force disappears, the spring 17 returns to its original position. This process enables the push plate 16 to drive the limiting part 12 to vibrate left and right, shaking out impurities inside the mold 2. During this process, the limiting part 12 always clamps the edge of the mold 2 to avoid vibration damage to the mold. The steam generated by the steam generator 8 heats the bottom of the mold from each branch pipe 20 upwards. Impurities falling inside the mold 2 are blocked by the top cap 21 and will not fall into the lower pipe. The annular groove 22 can be cleaned by periodically unscrewing the top cap 21.

[0040] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
