Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to a lubrication mechanism for a lead wire frame mold. Background Technology

[0002] A leadframe mold is a specialized mold used to produce leadframes, typically made of metal. Leadframes are essential components in electronic devices and integrated circuits, connecting chips to external leads. The design and manufacturing of leadframe molds require precision to ensure the production of accurate and standardized leadframes that meet the design requirements of electronic products. The lubrication mechanism of the leadframe mold is mainly used to reduce frictional wear on the moving parts of the mold, ensuring stamping accuracy and stability.

[0003] Chinese Utility Model Patent Publication No. CN222328854U discloses a wear-resistant self-lubricating mold. This wear-resistant self-lubricating mold automatically sprays lubricating oil through an oil spraying component, a motor, a pump body, an upper mold, and a lower mold to reduce mold wear and extend the mold's service life. An ejector component facilitates demolding of the pressed material, improving production efficiency. However, this wear-resistant self-lubricating mold lacks a protective mechanism, causing lubricating oil to splash onto the surfaces of the upper and lower molds due to pressure, potentially injuring workers and posing a safety risk. Furthermore, the lack of a recycling mechanism makes it difficult to collect dripping lubricating oil, resulting in unnecessary waste and low practicality, hindering its widespread use. Summary of the Invention

It can effectively solve the problems of existing technologies that do not have a protective mechanism, the lubricating oil on the surface of the upper and lower molds is squeezed and splashed, which can easily injure workers during operation, resulting in low safety. In addition, the lack of a recycling mechanism makes it inconvenient to collect the dripping lubricating oil, causing unnecessary waste, low practicality, and difficulty in promoting its use.

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.

[0031] Example 1: As Figure 1-8As shown, the present invention provides a lubrication mechanism for a lead frame mold, including a base 1 and a support plate 2. A protective component 3 and a stamping component 4 are fixedly installed on the side of the support plate 2 away from the base 1. A lubrication component 1 5 and a lubrication component 2 6 are provided on the side of the support plate 2 away from the base 1. A positioning groove 7, a collection groove 8 and a threaded hole 1 9 are provided on the side of the support plate 2 away from the base 1. A filter screen 10 is provided on the side of the support plate 2 away from the base 1. A threaded hole 2 11 is provided on the outer side of the filter screen 10. A bolt 12 is threadedly connected to the outer side of the filter screen 10. A collection pipe 13 is provided on the side of the support plate 2 close to the base 1. A lubricating oil tank 14 is fixedly installed inside the base 1. A control panel 15 is provided on the outer side of the base 1.

[0032] Specifically, the stamping assembly 4 includes a slide rod 401, a top plate 402, a hydraulic cylinder 403, a mounting plate 404, an upper die 405, and a lower die 406. The top plate 402 is fixedly installed on the end of the slide rod 401 away from the support plate 2. The hydraulic cylinder 403 is fixedly installed on the side of the top plate 402 away from the slide rod 401.

The upper die 405 and the lower die 406 are compatible. The advantage is that the operator places the workpiece to be stamped on the top of the lower mold 406, and then starts the hydraulic cylinder 403. The movable end of the hydraulic cylinder 403 extends and drives the mounting plate 404 to move downward, thereby driving the upper mold 405 to move downward, which can realize the rapid stamping of the workpiece. Through the cooperation of the mounting plate 404 and the slide bar 401, it plays a guiding role in the stamping process and improves the overall stability.

[0033] Specifically, the protective component 3 includes a protective cover 301, a protective door 302, a rotating plate 303, a limiting groove 304, a fixing block 305, and a slot 306.

The advantage is that when the operator rotates the protective door 302, it makes the protective door 302 collide with the protective cover 301. Then, the rotating plate 303 is rotated, so that the rotating plate 303 is locked into the interior of the limiting groove 304, which can realize the quick locking of the protective door 302. Through the design of the protective cover 301 and the protective door 302, the lubricating oil on the surface of the upper mold 405 and the lower mold 406 is prevented from being squeezed and splashed during stamping, making it less likely for the operator to be injured and providing high safety.

[0034] Specifically, the first lubrication component 5 includes an oil pump 501, a first oil pipe 502, a second oil pipe 503, a fixing column 504, a third oil pipe 505, and a nozzle 506. A first oil pipe 502 is provided between the oil pump 501 and the lubricating oil tank 14. A second oil pipe 503 is provided outside the oil pump 501. A fixing column 504 is fixedly installed on the side of the support plate 2 away from the base 1. A third oil pipe 505 is provided outside the fixing column 504. A nozzle 506 is fixedly installed outside the third oil pipe 505. The first lubrication component 5 and the second lubrication component 6 have the same structure. The second oil pipe 503 is a flexible pipe. The first oil pipe 502, the second oil pipe 503, and the third oil pipe 505 are connected. The advantage is that when the staff starts the oil pump 501, the oil pump 501 sucks out the lubricating oil inside the lubricating oil tank 14 through the first oil pipe 502, then discharges it into the third oil pipe 505 through the second oil pipe 503, and finally sprays it out through the nozzle 506, which can achieve rapid lubrication of the surface of the lower die 406. Similarly, through the design module of the second lubrication component 6, rapid lubrication of the surface of the upper die 405 can be achieved, reducing the wear of the upper die 405 and the lower die 406 during stamping, and improving the service life of the upper die 405 and the lower die 406.

[0035] Embodiment 2: As Figure 2-8 shown, as an improvement over the previous embodiment.

[0036] Specifically, a plurality of nozzles 506 are provided, and the plurality of nozzles 506 are evenly distributed at equal intervals. The advantage is that through the design of the plurality of nozzles 506, the lubrication area is increased, and the lubrication efficiency is further improved.

[0037] Specifically, the cross-section of the collection tank 8 is in a "hui" - shaped structure, and the lubricating oil tank 14, the collection pipe 13, and the collection tank 8 are connected. The advantage is that through the design of the collection tank 8, after the first lubrication component 5 and the second lubrication component 6 complete lubrication, the lubricating oil dripping from the upper die 405 and the lower die 406 flows into the collection tank 8. Then, the lubricating oil flows into the lubricating oil tank 14 through the collection pipe 13, recovering the dripping lubricating oil, avoiding waste, and improving the utilization rate of the lubricating oil.

[0038] Specifically, the filter screen 10 is installed by plugging into the positioning groove 7. The bolt 12 penetrates through the second threaded hole 11 and extends into the first threaded hole 9. The diameters of the second threaded hole 11 and the first threaded hole 9 are the same. The advantage is that the staff inserts the filter screen 10 into the positioning groove 7, and then penetrates the bolt 12 through the second threaded hole 11 and extends it into the first threaded hole 9, which can achieve the rapid installation of the filter screen 10. After long-term use, it is convenient to clean and replace it. Through the design of the filter screen 10, impurities in the dripping lubricating oil can be filtered, avoiding the accumulation of impurities inside the lubricating oil tank 14, and it has high practicality.

[0039] Working principle: During installation, the operator inserts the filter screen 10 into the positioning groove 7, and then inserts the bolt 12 through the threaded hole 11 to the threaded hole 9, enabling quick installation of the filter screen 10. After prolonged use, this facilitates cleaning and replacement. The operator then rotates the protective door 302, causing it to abut against the protective cover 301. Next, the operator rotates the rotating plate 303, causing it to engage with the limiting groove 304, enabling quick locking of the protective door 302. In use, the operator first connects to the external... Power is supplied, and then the worker places the workpiece to be stamped on top of the lower die 406. The hydraulic cylinder 403 is then activated, extending its movable end and causing the mounting plate 404 to move downwards, thereby moving the upper die 405 downwards. This enables rapid stamping of the workpiece. The mounting plate 404, in cooperation with the slide rod 401, acts as a guide during the stamping process, improving overall stability. When lubrication of the upper die 405 and the lower die 406 is required, the worker activates the oil pump 501, which pumps oil through the oil pipe... The lubricating oil in oil tank 14 is drawn out by nozzle 502, then discharged through oil pipe 503 to oil pipe 505, and finally sprayed out through nozzle 506. This achieves rapid lubrication of the surface of the lower mold 406. Similarly, the lubrication component 6 achieves rapid lubrication of the surface of the upper mold 405, reducing wear on the upper and lower molds 405 during stamping and improving their service life. The design of multiple nozzles 506 increases the lubrication area and further improves lubrication efficiency. With the design of the collection tank 8, after the lubrication of lubrication component 1 5 and lubrication component 2 6 is completed, the lubricating oil dripping from the upper mold 405 and the lower mold 406 flows into the inside of the collection tank 8. Then, the lubricating oil flows into the inside of the lubricating oil tank 14 through the collection pipe 13, which recovers the dripping lubricating oil, avoids waste, and improves the utilization rate of lubricating oil. With the design of the protective cover 301 and the protective door 302, the lubricating oil on the surface of the upper mold 405 and the lower mold 406 is prevented from being squeezed and splashed during stamping, making it less likely for workers to be injured and providing high safety.
