Description

Technical Field

[0001] The utility model relates to the field of stainless steel metal hand molds, in particular to a stainless steel metal hand mold forming die. Background Art

[0002] Disposable gloves are used in areas including medical care, hygiene, medical aesthetics, food processing, chemical industry, etc., and they play the role of isolation, protection, and infection prevention.

[0003] Disposable gloves are anti-static, aging-resistant and oil-resistant, easy to shape, flexible in shape, widely applicable, and highly flexible. They also have high stretchability and penetration resistance as well as tensile strength and wear resistance.

[0004] To increase the friction and anti-slip properties of disposable gloves and enhance their grip, some disposable gloves have a textured surface. Currently, some disposable gloves are produced using stainless steel metal molds. If textured surfaces are used, they are typically achieved through large-particle sandblasting. However, due to the hollow structure of stainless steel hands, the high pressure and velocity of the spray can cause the coarse sand particles to collapsing when they impact the product, resulting in a poor appearance. Furthermore, similar to ceramic textures, the textured surfaces of shot-blasted and sand-blasted surfaces exhibit poor consistency and varying depths, leading to poor molding results.

[0029] The following is combined with Figure 1-5 This application is described in further detail.

[0030] Example 1

[0031] A stainless steel metal hand mold forming mold, such as Figure 1 and Figure 2 As shown, it includes an upper mold 1 and a lower mold 2, wherein the lower mold 2 has a cavity 3 for placing half the palm of the metal hand mold. The metal hand mold is actually formed by splicing and welding two halves of the half palm. The cavity 3 has two symmetrically arranged sub-cavities 4, and the shapes of the sub-cavities 4 are adapted to the shape of the metal hand mold. At the same time, the upper mold 1 has an outward-convex punch 5, and the shape of the punch 5 is also adapted to the shape of the metal hand mold. Corresponding concave and convex textures 6 are provided on the bottom of the cavity 3 and the surface of the punch 5. In actual use, half the palm of the metal hand mold is placed in the cavity 3, and then the upper mold 1 is driven downward to press down the half palm of the metal hand mold with the help of the punch 5 to form the required concave and convex texture 6 on the surface of the metal hand mold.

[0032] By providing corresponding concave-convex textures 6 on the lower mold 2 and the upper mold 1, and then using a stamping method to form the concave-convex texture 6 on the metal palm, the depth of the concave-convex texture 6 can be controlled, and a depth of 0.1-1.0 mm can be achieved. The uniform concave-convex texture 6 appears on the glove, which increases the surface friction and anti-slip effect, thereby enhancing the grip of the glove product.

[0033] like Figure 1 and Figure 2 As shown, in this embodiment, the height of the concave-convex texture 6 in the cavity 3 is 0.05-0.1mm higher than the texture on the metal hand mold of the product. Because the stainless steel itself rebounds when the product is extruded, a certain amount of rebound needs to be increased to compensate for it to ensure that the final molded product can meet the production requirements. When the upper mold 1 and the lower mold 2 are closed, the distance from the high point of the concave-convex texture 6 on the punch 5 to the low point of the concave-convex texture 6 on the inner wall of the cavity 3 is less than 20-30% of the thickness of the metal hand mold, ensuring that the texture can be effectively formed.

[0034] like Figure 2 As shown, the upper mold 1 includes a template 7, which is provided with a through groove 8 that penetrates the template 7 and has a shape that matches the metal palm. The punch 5 is installed and fixed in the through groove 8. In this way, the punch 5 and the template 7 can be processed separately and independently and then fixed during the actual production and processing process, which effectively reduces the production difficulty of the upper mold 1 and makes production and processing simpler and easier.

[0035] Example 2

[0036] A stainless steel metal hand mold forming mold, such as Figure 3 and Figure 4 As shown, an adjusting block 9 is provided in the middle of the cavity 3. The adjusting block 9 is integrally formed with the lower mold 2. The adjusting block 9 is located in the middle of the two sub-cavities 4. At the same time, pressure blocks 10 for pressing the metal hand mold away from the finger are provided on opposite sides of the adjusting block 9. The pressure block 10 is horizontally slidably connected to the adjusting block 9. At the same time, a driving component is provided on the adjusting block 9 to drive the two pressure blocks 10 to move toward or away from each other.

[0037] Since there may be certain processing errors in the metal hand mold during the actual production process, it is easy for the metal hand mold to not be completely matched when placed in the mold cavity 3, resulting in poor fixing effect. Through the design of the adjustment block 9, the half palms of the two metal hand molds are placed in the sub-cavity 4 respectively, and then the two pressing blocks 10 are driven by the driving component to press the side of the metal hand mold away from the fingers, further fixing the metal palm, improving the stability of the metal hand mold in the mold cavity 3, and facilitating the subsequent forming of the concave and convex texture 6.

[0038] like Figure 3 and Figure 4As shown, the drive assembly includes a screw rod 11 and a push block 12. The screw rod 11 is rotatably connected to the adjusting block 9 and has a hexagonal hole 13 at its end. The screw rod 11 can be rotated by inserting a wrench into the hexagonal hole 13. The push block 12 is slidably connected to the inside of the adjusting block 9. At the same time, the screw rod 11 passes through the push block 12 and is threadedly connected to it. In this embodiment, the screw rod 11 has two threaded sections with opposite rotation directions, and the push block 12 has two corresponding threaded sections. The push block 12 and the pressure block 10 have inclined surfaces 14 that abut each other. In this way, the two push blocks 12 can be driven to move toward or away from each other by rotating the screw rod 11, and then the pressure block 10 is pushed to move away with the help of the setting of the inclined surface 14 to achieve compression and fixation of the metal palm.

[0039] like Figure 3 and Figure 4 As shown, a reset member connecting the adjusting block 9 and the pressing block 10 is provided between the adjusting block 9 and the pressing block 10. The reset member adopts a reset spring 15. One end of the reset spring 15 is fixed to the adjusting block 9, and the other end is fixed to the pressing block 10. The reset spring 15 is used to drive the two pressing blocks 10 to retract and reset toward each other. After the metal palm is stamped, the screw rod 11 is rotated to drive the two push blocks 12 to move back to back. The push blocks 12 retract and reset under the action of the reset spring 15 to release the metal palm.

[0040] like Figure 4 and Figure 5 As shown, an air duct is provided inside the lower mold 2, and the air duct includes a main air duct 16 and a branch air duct 17. One end of the branch air duct 17 passes through the inner wall of the cavity 3 corresponding to the finger part of the metal palm to form an air intake port 18, and the other end of the branch air duct 17 is a connecting port 19 and is connected to the main air duct 16. The end of the main air duct 16 away from the connecting port 19 is used to connect to the air intake source, so that in actual use, suction can be generated at the air intake port 18 by the air intake source to achieve adsorption of the palm part of each metal palm, thereby further improving the fixing effect of the metal palm.

[0041] like Figure 4 and Figure 5 As shown, an active cavity 20 for the push block 12 to slide is provided inside the adjustment block 9, and the communication port 19 is located at the active cavity 20. When the push block 12 drives the pressing block 10 to press the metal palm, the communication port 19 is staggered with the push block 12. At this time, the air intake 18 is connected to the air intake source to generate suction to further fix the finger part of the metal palm. When the push block 12 moves backward to release the metal palm, the push block 12 blocks the communication port 19. At this time, the air intake 18 does not generate suction, which facilitates the direct removal of the metal palm from the cavity 3.

[0042] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
