Description

Technical Field

[0001] The utility model relates to the production field of finger cot metal models, in particular to a forming die for producing finger cot models with textures. Background Art

[0002] The application fields of disposable finger cots include medical treatment, hygiene, medical aesthetics, food processing, chemical industry, etc., which play roles such as isolation, protection, and prevention of infection.

[0003] Disposable finger cots have the advantages of antistatic, aging and oil resistance, easy molding, flexible shaping, wide applicability, great flexibility, etc., and at the same time have high stretchability, penetration resistance, tensile strength and wear resistance.

[0004] In order to increase the friction and anti-slip effect of disposable finger cots and increase the grasping force of disposable finger cots, disposable finger cots all adopt a matte or convex dot surface structure.

[0005] Some disposable finger cots are produced by using glass hand molds. The surface of the glass finger cot is generally a sandblasted surface for the rough hemp, and it is very difficult to control the consistency of the hemp surface texture on the rough hemp surface, such as the size of the pit points, the consistency of the pit points, the consistency of the shape of the pit points, etc. The roughness fluctuates greatly, and the height difference consistency between the peak and bottom of the pit points is not good.

[0006] Some disposable finger cots are produced by using stainless steel metal models. If a matte surface is adopted, the method is large-particle sandblasting. Since the stainless steel hand adopts a hollow structure, due to the high injection pressure and fast injection flow rate, when the coarse sand grains impact the product, the surface of the model will collapse, resulting in poor appearance. At the same time, the matte surface of shot peening and sandblasting has the same problems as the glass matte surface, such as poor consistency and uneven depth. The matte surface formed by the particles formed by sandblasting far fails to meet the friction requirements of the finger cot. Summary of the Utility Model

[0007] In order to further improve the grasping force and friction of the produced finger cots, the present application provides a forming die for producing finger cot models with textures.

[0008] The present application provides a forming die for producing finger cot models with textures, and adopts the following technical solutions:

[0009] A forming die for producing finger cot models with textures includes an upper die and a lower die. The lower die is provided with positioning columns for placing the finger cot models. The upper die is provided with pressing blocks. A slider is horizontally slidably connected to the lower die. The sides of the slider and the pressing block facing the positioning columns have texture surfaces for forming textures on the finger cot models.

[0010] Optionally, a plurality of the sliders are evenly distributed around the circumference, and the texture surfaces on one side of the sliders are spliced to form a complete circumference.

[0011] Optionally, a vertical insertion knife is provided on the upper die, and a driving surface for abutting against the insertion knife is provided on the slider. When the insertion knife moves downward to abut against the driving surface, the slider is driven to move towards the positioning post.

[0012] Optionally, the side of the slider away from the positioning post is a vertical straight surface. When one side of the insertion knife abuts against the straight surface, the texture surface on the slider presses against the finger cot model to form a texture.

[0013] Optionally, the pressing block is vertically elastically connected to the upper die, and a connecting spring for connecting the two is provided between the upper die and the pressing block.

[0014] Optionally, one side of the bottom end of the insertion knife has an abutting surface for abutting against the driving surface, and both the abutting surface and the driving surface are arc surfaces.

[0015] Optionally, the texture surface has a plurality of forming bumps, and the forming bumps are used to form concave points on the finger cot model.

[0016] Optionally, the insertion knives and the sliders are arranged in one-to-one correspondence. A chute or a guide rail for the horizontal radial sliding of the sliders is provided on the lower die, and a reset member for driving the sliders to move back in the direction away from the positioning post is provided on the lower die.

[0017] Optionally, the connecting springs are symmetrically arranged and a telescopic rod is arranged inside them. The two ends of the telescopic rod are respectively connected to the upper die and the pressing block.

[0018] Optionally, the pressing block includes a seat body and a block body. The texture surface is arranged on the block body, and the block body is detachably connected to the seat body.

[0019] In summary, the present application includes at least one of the following beneficial technical effects:

[0020] 1. When the upper die moves downward to drive the pressing block to move downward, during which the slider is synchronously driven to move towards the finger cot model. The texture surface on the pressing block forms a texture on the fingertip surface of the finger cot model, and the texture surface on the slider forms a texture on the side wall of the end of the finger cot model. The texture depth is uniform, and the convex point texture of the finger cot can be realized according to different requirements of the finger cot, presenting as non-uniform or uniform convex point texture on the finger cot, which plays a role in increasing the surface friction and anti-slip, and effectively enhances the gripping force and friction of the finger cot product;

[0021] 2. Through the contact between the abutting surface on the insertion knife and the driving surface on the slider, when the insertion knife moves downward, the slider is synchronously driven to move, and linkage can be achieved without an additional driving source. The structure is simple and the cost is effectively reduced;

[0022] 3. The elastic connection between the pressure block and the upper die is realized through the design of the connecting spring, which can avoid the situation that the pressure block directly damages the finger cot model during stamping. Moreover, before stamping, the elastic force of the connecting spring can be used to drive the pressure block to preliminarily position the finger cot model. Description of the Drawings

[0030] The following further describes the present application in detail with reference to the Figures 1-5 drawings.

[0031] A forming mold for producing a finger cot model with texture, as Figures 1-3 shown, includes an upper die 1 and a lower die 2. A positioning post 3 for sleeving the finger cot model 4 is fixedly arranged at the top of the lower die 2. The shape of the positioning post 3 is adapted to the finger cot model 4. A pressure block 5 is arranged at the bottom of the upper die 1. The pressure block 5 is located directly above the positioning post 3 and is used to stamp the top end of the finger cot model 4 to form a texture. A slide block 6 is horizontally slidably connected to the lower die 2. A plurality of slide blocks 6 are evenly distributed around the circumference. In this embodiment, 3 slide blocks 6 are provided, and the 3 slide blocks 6 are spliced into a complete circle. The slide block 6 and the pressure block 5 have a textured surface 7 for forming a texture on the finger cot model 4 on the side facing the positioning post 3. The textured surface 7 is an arc surface that fits the surface of the finger cot model 4.

[0032] As Figures 1-3As shown in the figure, a vertically downward inserting knife 8 is further provided at the bottom of the upper die 1. The inserting knives 8 are arranged in one-to-one correspondence with the sliders 6. An arc-shaped abutting surface 10 is provided inside the bottom end of the inserting knife 8. A driving surface 9 for abutting against the abutting surface 10 is provided at the corner of the outer side of the slider 6. Both the abutting surface 10 and the driving surface 9 are arc surfaces to achieve a smooth and good abutting state. During the process of the inserting knife 8 moving downward with the upper die 1, the abutting surface 10 contacts the driving surface 9 to drive the slider 6 to move towards the finger sleeve model 4 until it abuts against the surface of the finger sleeve model 4 to form a texture surface 7. In this embodiment, the texture surface 7 has a plurality of forming convex points, and the forming convex points are used to form concave points on the finger sleeve model 4.

[0033] As Figures 1-3 shown, the pressing block 5 is elastically connected and fixed to the upper die 1. A connecting spring 11 for connecting the two is arranged between the pressing block 5 and the upper die 1. Two connecting springs 11 are symmetrically arranged. One end of the connecting spring 11 is fixed to the upper die 1, and the other end is fixed to the pressing block 5. In order to improve the stability of the up and down movement of the pressing block 5, a telescopic rod is inserted inside the connecting spring 11, and both ends of the telescopic rod are fixed to the upper die 1 and the pressing block 5 respectively. In this way, the pressing block 5 and the upper die 1 are not rigidly connected, avoiding the situation that the finger sleeve model 4 is directly damaged by hard contact when pressing down; when the upper die 1 moves downward until the driving surface 9 contacts the abutting surface 10, the pressing block 5 abuts against the top of the finger sleeve model 4 under the action of the connecting spring 11 to position it, ensuring that the position of the finger sleeve model 4 does not change when the subsequent slider 6 moves to form the texture surface 7, achieving a good forming effect; in addition, the outer surface side wall of the side of the slider 6 facing away from the finger sleeve model 4 is a vertical straight surface 12. After the inserting knife 8 moves downward until the abutting surface 10 is separated from the driving surface 9, the inner side wall of the inserting knife 8 abuts against the outer side wall of the slider 6. At this time, when the lower die 2 continues to move downward, it will not drive the slider 6 to move inward. The lower die 2 that continues to move downward makes the pressure of the connecting spring 11 on the pressing block 5 increase more and more until it moves to the limit position to complete the forming of the texture surface 7 at the top of the finger sleeve model 4.

[0034] As Figures 1-3 shown, a resetting member for driving the slider 6 to move away from the positioning post 3 and reset is provided on the lower die 2. The resetting member is a reset spring. One end of the reset spring is fixed to the slider 6, and the other end is fixed to the lower die 2. At the same time, a chute 13 or a slide rail for the horizontal sliding of the slider 6 is opened on the lower die 2. In this embodiment, the chute 13 is adopted to improve the stability of the horizontal movement of the slider 6. In this way, after the mold is opened, the slider 6 can return to its original position under the action of the reset spring, facilitating the removal of the finger sleeve model 4 and the insertion of the next finger sleeve model 4.

[0035] As Figure 1As shown, the briquetting block 5 includes a base body 14 and a block body 15. The textured surface 7 is provided on the block body 15. The block body 15 and the base body 14 are detachably connected by screws. In this way, when forming finger sleeve models 4 of different specifications, the briquetting block 5 can be disassembled and replaced to achieve better applicability.

[0036] Embodiment 2

[0037] A molding die for producing finger sleeve models with textures, as Figure 4 and Figure 5 shown. The main difference from Embodiment 1 lies in the different structure of the positioning post 3. In this embodiment, a vertical groove 16 is vertically provided in the positioning post 3. A vertical rod 17 is vertically slidably connected in the vertical groove 16. The top end of the vertical groove 16 penetrates through the top end of the positioning post 3, and the top end of the vertical rod 17 extends out of the top end of the positioning post 3. An elastic member for driving the vertical rod 17 to move upward and reset to expose its top end out of the positioning post 3 is provided at the bottom of the vertical groove 16. This elastic member is a return spring 18. At the same time, an air suction channel is provided inside the positioning post 3. The air suction channel includes a main channel 19 and branch channels 20. The branch channels 20 are communicated with the main channel 19. The bottom end of the main channel 19 penetrates through the lower die 2 to form an inlet 21 for connecting with an air suction source. A plurality of branch channels 20 are vertically and spaced apart. One end of the branch channel 20 is communicated with the main channel 19, and the other end penetrates through the outer wall of the positioning post 3 to form an air suction port 22. When the top end of the vertical rod 17 is exposed out of the positioning post 3, the main channel 19 and the branch channels 20 are misaligned, and at this time the air suction channel is not communicated. In this way, after the finger sleeve model 4 is placed on the positioning post 3, the upper die 1 moves downward and the briquetting block 5 drives the vertical rod 17 to move downward, and the return spring 18 is compressed. When the whole vertical rod 17 is located in the vertical groove 16, the main channel 19 and the branch channels 20 are communicated. At this time, the air suction port 22 generates a suction force to further adsorb and fix the finger sleeve model 4, improving the stability of the placement of the finger sleeve model 4. After the forming is completed and the mold is opened, the vertical rod 17 moves upward and resets under the action of the return spring 18, and the main channel 19 and the branch channels 20 are misaligned and not communicated. At this time, the air suction port 22 does not generate a suction force, and the vertical rod 17 moves upward to eject the finger sleeve model 4 to achieve the purpose of automatic demolding. The finger sleeve model 4 can be directly taken out, achieving the purpose of convenient demolding and material taking.

[0038] As Figure 4 and Figure 5 shown, an auxiliary channel 23 communicated with the air suction port 22 is further provided inside the lower die 2. One end of the auxiliary channel 23 is communicated with the air suction port 22, and the other end vertically penetrates through the top wall of the lower die 2 and is located at the slider 6. In this way, during the forming process, when the air suction port 22 is communicated with the main channel 19, the generated suction force can synchronously adsorb and fix the slider 6, improving the stability of the slider 6 during the forming process, and finally achieving the purpose of improving the forming effect.

[0039] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
