[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figure 1-6 This utility model provides a new technical solution: a high smoothness wear-resistant metal hand mold, including a hand mold body 1, the hand mold body 1 includes a palm part and a support rod part, two locking holes 22 are opened on the outer surface of the support rod part of the hand mold body 1, a left half of the hand mold 2 is provided on the hand mold body 1, and a right half of the hand mold 3 is provided on the hand mold body 1.

[0034] The hand mold body 1 is provided with a connecting mechanism, which includes multiple limiting rods 4, fixing blocks 5, two first spring grooves 6, four first springs 7, two locking blocks 8, multiple limiting holes 9, slots 10, two locking grooves 11, a chemical nickel layer 12, a ceramic film layer 13, a ceramic paint layer 14, a hand mold fixing base 15, a sliding groove 16, a second spring 17, a fixing plate 18, a ring 19, a round hole 20, a round bead 21, and a locking hole 22.

[0035] Furthermore, multiple limiting rods 4 are fixedly installed on the right surface of the left half of the hand mold 2, and a fixing block 5 is fixedly installed on the right surface of the left half of the hand mold 2.

[0036] Furthermore, two first spring grooves 6 are respectively formed on the upper and lower surfaces of the fixing block 5, and four first springs 7 are respectively fixedly installed in the inner walls of the two first spring grooves 6.

[0037] Furthermore, two locking blocks 8 are fixedly installed on opposite ends of the four first springs 7, and the two locking blocks 8 are slidably sleeved in the inner walls of the two first spring grooves 6, with the right surfaces of the two locking blocks 8 being inclined.

[0038] Furthermore, multiple limiting holes 9 are formed on the left surface of the right half of the hand mold 3, and slots 10 are formed on the left surface of the right half of the hand mold 3.

[0039] Two slots 11 are formed in the inner wall of the slot 10.

[0040] Furthermore, a chemical nickel layer 12 is provided on the outer surface of the hand mold body 1;

[0041] Among them, a ceramic film layer 13 is provided on the outer surface of the hand mold body 1;

[0042] Among them, the outer surface of the hand mold body 1 is provided with a ceramic paint layer 14;

[0043] Furthermore, a hand mold fixing base 15 is provided on the outer surface of the hand mold body 1, a slide groove 16 is opened on the outer surface of the hand mold fixing base 15, two second springs 17 are fixedly installed in the inner wall of the slide groove 16, and two fixing plates 18 are fixedly installed on the upper surface of the two second springs 17, with the opposite surfaces of the two fixing plates 18 being inclined.

[0044] Among them, the ring 19 is fixedly sleeved on the outer surface of the two fixing plates 18, the two round holes 20 are opened on the inner surface of the slide groove 16, and the two round beads 21 are disposed in the inner wall of the two round holes 20.

[0045] When using this high-smoothness, wear-resistant metal hand mold, the limiting rod 4, which is fixedly installed on the right surface of the left half 2 of the hand mold, is inserted into the limiting hole 9 opened on the left surface of the right half 3 of the hand mold for connection. This method limits the fingers on the hand mold and prevents them from shifting after welding. At the same time, the fixing block 5, which is fixedly installed on the right surface of the left half 2 of the hand mold, is inserted into the slot 10. During the insertion, the inclined surface of the locking block 8 on the fixing block 5 impacts the inner wall of the slot 10. At this time, the two locking blocks 8 are subjected to force on the opposite fixed surfaces of the first finger. A spring 7 applies pressure, causing it to contract. Simultaneously, the locking block 8 retracts into the first spring groove 6. At this point, the locking block 8 is inserted deep into the locking groove 11. Having passed through both locking grooves 11, the locking block 8 is no longer under pressure, and the first spring 7 expands. The first spring 7 applies a thrust to the locking block 8 fixed at the opposite end, causing it to engage with the two locking grooves 11 for fixation. This method ensures a tighter weld joint during welding, preventing opening and closing, and facilitating welding. When changing to a different hand mold body 1, an upward pushing force is applied to the ring 19 to move it upward. At the same time, the ring 19 drives the two fixed plates 18 fixedly mounted on the inner surface to move upward. At this time, the two fixed plates 18 apply pressure to the two second springs 17 fixedly mounted on the upper surface, causing them to contract. At this time, the two fixed plates 18 no longer block the two round holes 20, that is, they no longer limit the two round beads 21 set in the two round holes 20. Then, the support rod of the hand mold body 1 is inserted into the inner surface of the hand mold fixing base 15. At this time, no upward pushing force is applied to the ring 19, and the two second springs 17 are no longer under force. At this time, the two second springs 17 expand and apply a downward pushing force to the two fixed plates 18 fixedly installed on the right end, causing them to slide downward in the inner wall of the slide groove 16. At this time, the inclined surfaces of the two fixed plates 18 strike the two balls 21 and apply a pushing force to the two balls 21 on opposite surfaces, causing the two balls 21 to move towards the opposite surfaces and engage with the locking holes 22 opened on the outer surface of the support rod part of the hand mold body 1 for locking and fixing.

[0046] This high-smoothness, wear-resistant metal hand mold uses limiting rods 4 and limiting holes 9 to limit the fingers on the hand mold, preventing displacement after welding. It also uses a snap-fit ​​method to connect the left half 2 and the right half 3 of the hand mold, making the gaps more tight and less prone to opening and closing during welding, thus facilitating welding. Furthermore, this high-smoothness, wear-resistant metal hand mold has a protective layer on the surface of the main body of the hand mold. The protective layer includes an electroless nickel layer 12, a ceramic film layer 13, and a ceramic paint layer 14. The electroless nickel layer 12 is applied to the surface of the hand mold body 1 using an electroless nickel plating process. The ceramic film layer 13 is applied to the surface of the hand mold body 1 using a micro-arc oxidation process. The ceramic paint layer 14 is applied to the surface of the hand mold body 1 using an electrostatic spraying process. This method makes the surface of the hand mold body 1 smoother, without depressions or holes, making it easier to use. This high-smoothness, wear-resistant metal hand mold can be installed and fixed to the hand mold body by snap-fitting. Compared with the traditional hand mold body using welding fixation, which is inconvenient when replacing the hand mold body, the snap-fitting method allows for quick replacement of the hand mold, making it more convenient for producing gloves of different sizes.

[0047] Working principle: When using this high-smoothness, wear-resistant metal hand mold, the limiting rod 4, which is fixedly installed on the right surface of the left half 2 of the hand mold, is inserted into the limiting hole 9 opened on the left surface of the right half 3 of the hand mold for connection. This method limits the fingers on the hand mold and prevents displacement after welding. At the same time, the fixing block 5, which is fixedly installed on the right surface of the left half 2 of the hand mold, is inserted into the slot 10. During the insertion, the inclined surface of the locking block 8 on the fixing block 5 impacts the inner wall of the slot 10. At this time, the two locking blocks 8 are subjected to force to fix the opposite surfaces. The first spring 7 is pressurized, causing it to contract. Simultaneously, the locking block 8 retracts into the first spring groove 6. At this point, the locking block 8 is inserted deep into the locking groove 11. Having passed through both locking grooves 11, the locking block 8 is no longer under pressure, and the first spring 7 is also no longer under pressure. The first spring 7 then expands, applying a thrust to the locking block 8 fixed at the opposite end, causing it to engage with the two locking grooves 11 for fixation. This method ensures a tighter weld joint during welding, preventing opening and closing, and facilitating welding. When a different hand mold body 1 needs to be replaced, an upward pushing force is applied to the ring 19 to move it upward. At the same time, the ring 19 drives the two fixing plates 18 fixedly mounted on the inner surface to move upward. At this time, the two fixing plates 18 apply pressure to the two second springs 17 fixedly mounted on the upper surface, causing them to contract. At this time, the two fixing plates 18 no longer block the two round holes 20, that is, they no longer limit the two round beads 21 set in the two round holes 20. Then, the support rod of the hand mold body 1 is inserted into the inner surface of the hand mold fixing base 15. At this time, no upward thrust is applied to the ring 19, and the two second springs 17 are no longer under force. At this time, the two second springs 17 expand and apply a downward thrust to the two fixed plates 18 fixed at the right end, causing them to slide downward in the inner wall of the slide groove 16. At this time, the inclined surfaces of the two fixed plates 18 strike the two balls 21 and apply a thrust to the two balls 21 on opposite surfaces, causing the two balls 21 to move towards the opposite surfaces and engage with the locking holes 22 opened on the outer surface of the support rod part of the hand mold body 1 for locking and fixing.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
