Description

Technical Field

[0001] This utility model relates to the field of hardware mold technology, specifically a hardware mold that reduces wear. Background Technology

[0002] The utility model patent application with publication number CN219664928U includes a lower stamping die, an upper stamping die, and a transverse flow channel, as well as a longitudinal flow channel and an overflow hole. The upper stamping die is located on top of the lower stamping die, and a top plate is located on top of the upper stamping die. Transverse and longitudinal flow channels are evenly spaced within both the lower and upper stamping dies, and these channels are interconnected. This provides a wear-resistant and self-lubricating stamping die for metal processing, ensuring the strength of the stamping surface of the die.

[0003] The advantages are: by automatically discharging lubricating fluid, the stamping surface of the mold is more lubricated, greatly reducing wear and tear. This solves the problem that existing stamping dies suffer severe lubrication damage after long-term stamping, which affects the forming quality of metal stamping products, because the stamping surface is not coated for protection or lubricated.

[0004] In the prior art, including the aforementioned patents, injecting lubricant into stamping dies can effectively achieve anti-wear effects. However, most current injection equipment relies on the equipment itself to extract the lubricant. This requires pre-setting the equipment to ensure that lubricant is not continuously extracted. Furthermore, since dies are mostly mass-produced, it is not feasible to equip each die with a pump to extract lubricant, as this would significantly increase the manufacturer's production costs. Utility Model Content

[0005] The purpose of this utility model is to provide a hardware mold that reduces wear, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wear-reducing hardware mold, comprising a mold, with racks provided on both sides of the top of the outer wall of the mold, and linkage wheels movably mounted on both sides of the bottom of the outer wall of the mold. A driving bevel gear is mounted on one side of the linkage wheel via a coupling, a driven bevel gear is movably mounted on the top of the driving bevel gear, and a main connecting rod is mounted on the top of the driven bevel gear via a coupling. A secondary connecting rod is movably connected to one end of the main connecting rod, and a push rod is movably mounted on one end of the secondary connecting rod. A sliding groove is provided on the outer wall of the push rod, and a piston head is connected to one end of the push rod.

[0007] Furthermore, a piston valve is provided on the outer wall of the piston head, and the output end of the piston valve is connected to a pipe, one end of which is connected to a lubricant storage tank.

[0008] Furthermore, a nozzle is connected to the other end of the pipe, a pressing block is provided on the inner wall of the mold, and a placement plate is provided at the bottom of the inner wall of the mold.

[0009] Furthermore, the tooth grooves of the rack mesh with the tooth grooves of the linkage wheel, and the rack and the linkage wheel form a meshing transmission connection.

[0010] Furthermore, one end of the main connecting rod is connected to the driven bevel gear via a coupling, and the other end of the main connecting rod is movably connected to a secondary connecting rod.

[0011] Furthermore, the piston head is movably mounted on the inner wall of the piston valve, and the outer wall of the piston head is connected to one end of the push rod.

[0012] Furthermore, the inner wall of the pressing block is provided with a cavity, and the cavity of the pressing block is arranged laterally on both sides of the outer wall of the pressing block.

[0013] Compared with the prior art, the beneficial effects of this utility model are: this wear-reducing hardware mold is reasonable and has the following advantages:

[0014] (1) The nozzle is started by the power of the mold itself to spray out lubricating fluid, which reduces the wear of the hardware mold during the stamping process and thus improves the quality of the finished product. When the mold is pressed down, the rack drives the piston valve to start, so that the nozzle sprays out lubricating fluid to lubricate the mold and the parts. A lubricating film can be formed during the stamping process, which effectively reduces the friction between the mold and the material, reduces heat generation, thereby reducing wear, extending the mold life, and improving the processing quality of hardware products. Reducing the wear of the mold will lead to a decrease in product dimensional accuracy and a decrease in surface quality.

[0015] (2) In the existing technology, although oil spraying lubrication of stamping dies can effectively achieve the effect of anti-wear, in most cases it requires additional equipment to extract and transport the lubricant, which not only increases the complexity of the equipment, but also increases the production cost. This design uses an automatic nozzle to spray lubricant when the die is pressed down, eliminating the need for additional pumps and conveying equipment, simplifying the production process, reducing equipment maintenance costs and production costs, and also allowing for precise control of the amount of lubricant sprayed, making the die more suitable for mass production.

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.

[0024] Please see Figure 1-6 The technical solution provided by this utility model is as follows:

[0025] Example 1:

[0026] In this embodiment, a wear-reducing hardware mold includes a mold 1. Racks 2 are provided on both sides of the top of the outer wall of the mold 1. Linkage wheels 3 are movably installed on both sides of the bottom of the outer wall of the mold 1. A driving bevel gear 4 is installed on one side of the linkage wheel 3 via a coupling. A driven bevel gear 5 is movably installed on the top of the driving bevel gear 4. A main connecting rod 6 is installed on the top of the driven bevel gear 5 via a coupling. A secondary connecting rod 7 is movably connected to one end of the main connecting rod 6. A push rod 8 is movably installed on one end of the secondary connecting rod 7. A sliding groove 9 is provided on the outer wall of the push rod 8. A piston head 10 is connected to one end of the push rod 8.

[0027] In this embodiment, a piston valve 11 is provided on the outer wall of the piston head 10, and the output end of the piston valve 11 is connected to a pipe 12. One end of the pipe 12 is connected to a lubricant storage tank 13.

[0028] In this embodiment, the other end of the pipe 12 is connected to a nozzle 14, the inner wall of the mold 1 is provided with a pressing block 15, and the bottom of the inner wall of the mold 1 is provided with a placement plate 16.

[0029] In this embodiment, the tooth groove of the rack 2 meshes with the tooth groove of the linkage wheel 3, and the rack 2 and the linkage wheel 3 form a meshing transmission connection. When the rack 2 moves, it will drive the linkage wheel 3 to rotate.

[0030] In this embodiment, one end of the main connecting rod 6 is connected to the driven bevel gear 5 via a coupling, and the other end of the main connecting rod 6 is movably connected to the auxiliary connecting rod 7. When the driven bevel gear 5 rotates, it will drive the auxiliary connecting rod 7 to rotate through the main connecting rod 6.

[0031] In this embodiment, the piston head 10 is movably mounted on the inner wall of the piston valve 11, and the outer wall of the piston head 10 is connected to one end of the push rod 8. When the piston head 10 moves back and forth, the piston valve 11 will be in a working state.

[0032] In this embodiment, the inner wall of the pressing block 15 is provided with a cavity, and the cavity of the pressing block 15 is arranged laterally on both sides of the outer wall of the pressing block 15. The lubricating liquid sprayed by the nozzle 14 can enter the interior of the pressing block 15 through the cavity of the pressing block 15.

[0033] Working principle: In use, the user first places the hardware on the placement plate 16, then starts the mold 1. After the mold 1 starts, it will drive the rack 2 to move downwards. When the rack 2 moves downwards, it will drive the linkage wheel 3 to rotate. When the linkage wheel 3 rotates, it will drive the driving bevel gear 4 to rotate. When the driving bevel gear 4 rotates, it will drive the driven bevel gear 5 to rotate. When the driven bevel gear 5 rotates, it will drive the main connecting rod 6 to rotate. When the main connecting rod 6 rotates, it will drive the secondary connecting rod 7 to rotate synchronously. When the secondary connecting rod 7 rotates, it will drive the push rod 8 to slide back and forth on the outer wall of the slide groove 9. When the push rod 8 slides, it will cause the piston head 10 to slide against the inner wall of the piston valve 11. The reciprocating motion puts the piston valve 11 into operation. At this time, the lubricant in the lubricant storage tank 13 will enter the nozzle 14 through the pipe 12 and be sprayed out. The lubricant sprayed from the nozzle 14 will first spray onto the outside of the hardware on the placement plate 16. As the rack 2 is pressed down, the pressing block 15 and the placement plate 16 will gradually fit together. At this time, the lubricant sprayed from the nozzle 14 will enter the cavity of the pressing block 15 to lubricate the clamping parts. The lubricant can reduce the wear of the mold 1 during operation, thereby improving the quality of the finished product. Moreover, this utility model does not require an additional pump body for oil spraying, making it suitable for mass production and greatly saving the manufacturer's costs. Thus, the utility model is completed.
