[0002] In the glove production line, the hand mold base is used to fix and guide the glove mold to ensure that the glove can be evenly formed during the production process;

[0003] According to the different requirements of the production line, the hand mold base can be made of various materials such as PVC, nylon, alloy steel, etc. to meet different wear resistance, corrosion resistance and life requirements. For example, the Chinese utility model patent disclosed in the publication number CN205969687U: hand mold base. In this application, it is disclosed that it includes a chassis, and a positioning seat for cleaning and positioning is provided on the chassis. The positioning seat is fixedly connected to the chassis. The positioning seat includes two relatively arranged positioning planes and two relatively arranged positioning arc surfaces. Generally, the chassis and the positioning seat, the components of the hand mold base, are fixedly connected by welding. And in order to make the connection between the chassis and the positioning seat more firm, the two positioning arc surfaces are partially welded on the chassis. The existing welding method mostly manually combines the chassis and the positioning seat, and then holds the welding equipment to weld the top of the chassis and the two positioning arc surface parts on the outside of the positioning seat. As a result, when welding the chassis and the positioning seat by this welding method, the welding efficiency is not high, and the quality of the welding surface is greatly affected by the operation skills of the personnel.

[0033] Embodiment 2

[0034] Referring to Figures 3-6 , which is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is that:

[0035] Compared with Embodiment 1, further, arc-shaped through grooves 18 are respectively opened on both sides inside the gear box 7, and two rotating grooves 19 are respectively opened at the bottom and the bottom inside the gear box 7. By means of the opening of the rotating grooves 19, the two gears 9 can rotate stably inside the gear box 7. The opening of the arc-shaped through grooves 18 can ensure that one side of the linkage plate 10 extends outside the gear box 7 to swing. A spring rod 27 is fixedly installed at the center position of the bottom of the gear box 7. Fixed shafts 21 are respectively fixedly installed at the center positions of the two gears 9. A fixed seat 20 is also fixedly installed at the position of the fixed shaft 21 above the gear 9. The top and bottom of the fixed shaft 21 are respectively rotatably installed in the corresponding rotating grooves 19, and the two gears 9 are meshed and connected inside the gear box 7. The output end of the first motor 8 is fixedly connected to the top of one of the fixed shafts 21 passing through the gear box 7. The output end of the first motor 8 is fixedly connected to the top of one of the fixed shafts 21 passing through the gear box 7. An installation hole 22 is opened on one side of the linkage plate 10, and a telescopic groove 23 is opened on the other side of the linkage plate 10. The linkage plate 10 is inserted through the installation hole 22 on the corresponding fixed seat 20 and fixed by screws. A fixed tube 24 is fixedly installed on one side of the telescopic plate 11. The other side of the telescopic plate 11 is inserted into the telescopic groove 23 and fixed by screws. By installing one side of the linkage plate 10 on the fixed seat 20, when the gear 9 rotates, the linkage plate 10 and the telescopic plate 11 can be driven to swing, so that the telescopic plate 11 drives the welding torch 12 to rotate circumferentially through the fixed tube 24. An installation frame 17 is fixedly installed on the rear side of the gear box 7. The rear side of the installation frame 17 is fixedly installed on the front side of the installation table 16. A positioning seat 25 is fixedly installed on the bearing bracket 3. Through the setting of the positioning seat 25, it is convenient to position and place the hand mold base 26, so that the hand mold base 26 is convenient for the welding mechanism 6 to weld two parts of the hand mold base 26.

[0036] It should be noted that the present utility model is an arc surface welding device for a hand mold base. When welding two components of the hand mold base 26, the bottom of the hand mold base 26 can be placed into the positioning groove on the positioning seat 25. Then, the second motor 14 is started through the controller 2. Thus, the second motor 14 drives the lead screw 15 to rotate, and the lead screw 15 also rotates in the screw hole at the rear side of the mounting table 16, so that the mounting table 16 moves downward in front of the shaft frame 13. Then, the mounting table 16 drives the gear box 7 to move downward through the mounting frame 17, and when the spring rod 27 at the bottom of the gear box 7 presses on the hand mold base 26 and compresses a certain process, the spring rod 27 presses and fixes the two components of the hand mold base 26 to be welded. And one end of each of the two welding torches 12 is placed at the joint of the two parts of the hand mold base 26 to be welded. At this time, the controller 2 automatically starts the first motor 8, and the first motor 8 drives one of the gears 9 to rotate, so that one of the gears 9 synchronously drives the other gear 9 to rotate in the gear box 7. Then, the two gears 9 rotate relatively or in the opposite direction, and further, the two gears 9 respectively drive the corresponding linkage plates 10 to rotate through the fixing seats 20 at the top. Then, the two linkage plates 10 respectively drive the corresponding welding torches 12 to move axially along the arc welding surfaces of the two parts of the hand mold base 26, and the two parts of the hand mold base 26 can be welded together. Then, the second motor 14 drives the lead screw 15 to rotate in the reverse direction, and the mounting table 16 can be moved upward, so that the mounting table 16 drives the gear box 7 to move upward through the mounting frame 17. Then, the gear box 7 drives the gears 9, the spring rod 27 and the welding torches 12 to move upward. At this time, the welded hand mold base 26 can be taken off, and the other components of the hand mold base 26 can be placed on the positioning seat 25 to repeat the above actions.
