[0032] Reference Figure 1-Figure 3 A moving unit is provided on the outer side of the mold body 4, and the moving unit includes a screw 52, ​​which is rotatably connected to the front end of the upper surface of the platform 1, and the front and rear surfaces of the mold body 4 are fixedly connected with a fixing plate 51, and when the fixing plate 51 moves, the mold body 4 can be driven to move synchronously, and the top of the screw 52 passes through the fixing plate 51 located on the front side of the mold body 4, and the screw 52 is threadedly connected with the fixing plate 51 located on the front side of the mold body 4. When the screw 52 rotates, the mold body 4 can be driven to move synchronously through the fixing plate 51 located on the front side, and the top of the screw 52 is fixedly connected with a round block 53, and the outer side of the round block 53 is provided with an anti-slip pattern The staff can quickly rotate the screw 52 through the round block 53, and the rear end of the upper surface of the platform 1 is fixedly connected to the limit rod 54. The top of the limit rod 54 passes through the fixed plate 51 located at the rear end of the mold body 4. The limit rod 54 can cooperate with the screw 52 to guide and limit the movement of the mold body 4, so that the mold body 4 can only perform linear motion in the up and down directions, and then the round block 53 can be rotated to drive the mold body 4 to perform linear motion in the up and down directions. When the heat insulation cover is welded, the round block 53 can be rotated to drive the mold body 4 to move upward, release the contact with the bottom plate 2 of the heat insulation cover, and facilitate the staff to disassemble and take the heat insulation cover.

[0033] A positioning column 6 is fixedly connected to the left surface of the tire body 4. The distance between the positioning column 6 and the positioning groove is consistent with the thickness of the spacer 3. The positioning column 6 is sleeved inside the spacer 3. The left side of the positioning column 6 is rotatably connected to a rotating plate 7. The lower end of the rotating plate 7 can rotate around the positioning column 6. In the initial state, the rotating plate 7 is restricted so that the bottom end and the bottom surface of the positioning column 6 are in the same horizontal plane. At this time, the upper end of the rotating plate 7 is higher than the positioning column 6. When the spacer 3 is placed and sleeved on the outside of the positioning column 6, the rotating plate 7 can limit the spacer 3 to prevent the spacer 3 from falling off the positioning column 6. A rectangular through groove 8 is opened on the left surface of the rotating plate 7. The rectangular through groove 8 runs through the rotating plate 7. A rectangular block 9 is inserted into the inside of the rectangular through groove 8. The rectangular block 9 can be inside the rectangular through groove 8 To perform linear motion in the left and right directions, an inner groove is provided on the left surface of the rectangular block 9, and the staff can insert their fingers into the inner groove to move the rectangular block 9. A limiting unit is provided at the right end of the rectangular block 9, and the limiting unit includes a circular groove 91, which is provided on the right surface of the positioning column 6. A spring 92 is fixedly connected to the right inner wall surface of the circular groove 91, and the left end of the spring 92 is fixedly connected to a limiting column 93. When the limiting column 93 moves to the left, the spring 92 is pulled, so that the spring 92 stretches to generate elastic potential energy. The left end of the limiting column 93 is fixedly connected to the right surface of the rectangular block 9, and the limiting column 93 is sleeved inside the circular groove 91. The limiting column 93 can perform linear motion in the left and right directions inside the circular groove 91.

[0034] The set limiting unit can limit the rectangular block 9. When the rectangular block 9 moves to the left, the spring 92 can be pulled. At this time, the limit of the rotating plate 7 can be released, so that the rotating plate 7 can be rotated. After the rotating plate 7 rotates half a circle, the rectangular through groove 8 will resume alignment with the rectangular block 9. At this time, loosening the rectangular block 9 can allow the rectangular block 9 to reset under the elastic potential energy of the spring 92 and return to the inside of the rectangular through groove 8 to limit and fix the rotating plate 7. When the heat insulation cover bottom plate 2 is placed under the mold body 4 and the spacer 3 is set on the outside of the positioning column 6 for limiting, the moving unit is started to move the mold body 4 downward. When the spacer 3 is released from the heat insulation cover bottom plate 2, pull The rectangular block 9 releases the limit on the rotating plate 7 and rotates the rotating plate 7 half a circle, and then the rectangular block 9 is released so that the rectangular block 9 is reset and enters the rectangular through groove 8 under the action of the limiting unit to limit the rotating plate 7, and the mold body 4 is continued to be driven to move by the moving unit, so that the heat insulation cover bottom plate 2 is completely entered into the positioning groove. At this time, the positioning column 6 can limit the spacer 3, so that the spacer 3 cannot move in a straight line in the front and rear directions, and the heat insulation cover bottom plate 2 and the spacer 3 can be moved synchronously to the left side. When the heat insulation cover bottom plate 2 and the spacer 3 are both in contact with the right side surface of the rotating plate 7, the alignment can be completed quickly, which can speed up the alignment speed between the heat insulation cover bottom plate 2 and the spacer 3, thereby improving the processing efficiency.

[0035] Reference Figure 4The left surface of the platform 1 is fixedly connected with an inclined plate 10, the rear end of the upper surface of the platform 1 is fixedly connected with a slide rail 11, the inner part of the slide rail 11 is slidably connected with a slider 12, and the front end of the slider 12 is fixedly connected with a scraper 13. The scraper 13 can perform linear motion in the left and right directions under the limit of the slide rail 11 and the slider 12. The bottom surface of the scraper 13 is in contact with the upper surface of the platform 1. When the scraper 13 moves to the left, the placement position of the heat insulation cover bottom plate 2 can be scraped and cleaned, and the welding slag generated during the welding process can be pushed to the left to the inclined plate 10, so as to improve the welding performance. A collecting container is arranged below the inclined plate 10, so that the welding slag can enter the collecting container along the inclined surface of the inclined plate 10 for collection, and the operation is simple. A magnetic plate 14 is fixedly connected to the right end of the upper surface of the platform 1, and the magnetic plate 14 is embedded in the upper surface of the platform 1. The upper surface of the magnetic plate 14 and the upper surface of the platform 1 are located on the same horizontal plane, and the bottom surface of the scraper 13 can be made of iron material. After the scraper 13 is used, the scraper 13 can be moved to the rightmost end. At this time, the magnetic plate 14 can limit the scraper 13 to prevent the scraper 13 from obstructing the placement of the bottom plate 2 of the heat insulation cover.

[0036] Working principle: Place the heat shield bottom plate 2 under the positioning groove, and after the spacer ring 3 is sleeved on the outside of the positioning column 6, the mold body 4 is driven to move downward by the moving unit so that the heat shield bottom plate 2 enters the positioning groove. When the spacer ring 3 contacts the heat shield bottom plate 2, pull the rectangular block 9 to the left to release the limit on the rotating plate 7. After the rotating plate 7 is rotated half a circle, the rectangular block 9 is released, so that the rectangular block 9 automatically moves to the right and resets under the action of the limiting unit. Then, the mold body 4 is continued to be driven downward by the moving unit so that the heat shield bottom plate 2 completely enters the positioning groove. At this time, the positioning column 6 can limit the spacer ring 3 to prevent the spacer ring 3 from offsetting forward and backward and affecting the welding accuracy. At the same time, the heat shield bottom plate 2 and the spacer ring 3 can be moved so that the left surfaces of the two are in contact with the rotating plate 7, and they can be quickly aligned to improve the processing efficiency. After the processing is completed, the mold body 4 is driven upward by the moving unit to quickly take out the semi-finished heat shield product, which is easy to operate.
