Especially after entering the digital age, higher and newer requirements are put forward for electronic components. Therefore, such electronic components are widely used and have a large demand. At the same time, the stamping and tapping efficiency and quality are very important.

[0003] At present, the most common product production equipment is mainly divided into a stamping machine and a tapping machine. When producing products, first use the stamping machine to stamp the products. When stamping, it is easy for the products to be difficult to strip and move with the upper template. After stamping the products, place them on the tapping machine for tapping. Inevitably, it is necessary to align the tapping position twice during tapping, which is not only relatively time-consuming and laborious, with relatively low production efficiency, but also unable to guarantee the positioning accuracy during tapping. Based on this, the utility model provides an in-mold tapping stamping production device. Content of the Utility Model

[0019] The present utility model will be further described below with reference to the accompanying drawings.

[0020] According to the attached Figure 1 , 2 , as shown in FIGS. 4: The present utility model provides an in-mold tapping stamping production device, including a lower die base 1, an upper die base 2. At the bottom of the upper die base 2, there is an upper backing plate 15 that cooperates with the lower backing plate 4. At the bottom of the upper backing plate 15, there is an upper clamping plate 16 that cooperates with the lower template 5. At the top of the lower die base 1, there is a lower backing plate 4. At the top of the lower backing plate 4, there is a lower template 5. Above the lower template 5, there is a stripping plate 6. At the top of the stripping plate, there is a stop plate 7. On both sides of the bottom of the upper clamping plate 16, symmetrically arranged are upper die bearing blocks 20 placed above the stop plate 7. On the lower die base 1, symmetrically arranged are two demolding tapping assemblies 25. The demolding tapping assembly 25 includes a rotating slider fixed seat 8. At the top of the rotating slider fixed seat 8, there is a cooperating rotating slider 9. On one side of the rotating slider 9, there is a screw 10 that passes through the lower backing plate 4, the lower template 5 and is fixedly connected to the stripping plate 6. A first stripping spring 11 is sleeved on the screw 10 and is placed between the stripping plate 6 and the lower backing plate 4. On the other side of the rotating slider 9, there is a support block 12. At the top of the support block 12, there is a tap needle fixing block 13. At the top of the tap needle fixing block 13, there is a tap needle 14 that passes through the lower backing plate 4 and the lower template 5. The rotating slider fixed seat 8 is arranged inside the lower die base 1. The rotating slider 9 and the screw 10 are rotationally connected through a provided pin 1 22. At the top of the rotating slider fixed seat 8, there is a bracket. The bracket and the rotating slider 9 are rotationally connected through a provided pin 2 23. On the stripping plate 6, there is a nut 24 connected to the end of the screw 10. Place the product to be stamped and tapped on the lower template 5, move the upper die base 2 towards the lower die base 1 until the upper die bearing block 20 abuts against the stop plate 7. Then continue to move the upper die base 2, driving the stop plate 7 and the stripping plate 6 to move downward until the stripping plate 6 is closely attached to the top of the product, so as to be able to stamp the product. During the downward movement of the stripping plate 6, the screw 10 can be driven to move downward, so that one side of the rotating slider 9 moves downward, causing the first stripping spring 11 to be compressed under force. The other side of the rotating slider 9 moves upward, driving the support block 12, the tap needle fixing block 13, and the tap needle 14 to move towards the lower die base 1, so as to be able to strongly press the product between the stripping plate 6 and the lower template 5 while realizing the tapping work on the product.

[0021] As shown in the attached Figure 1 、 3 、Figure 4: A stripping structure 3 is provided on the upper die base 2. The stripping structure 3 includes a stop screw 17 located inside the upper die base 2. A second stripping spring 18 is provided at the top of the stop screw 17. A stripping ejector pin 19 is provided at the top of the second stripping spring 18 and is placed above the tapping pin 14. A through hole is provided between the upper die base 2, the upper backing plate 15, and the upper clamping plate 16 outside the stop screw 17, the second stripping spring 18, and the stripping ejector pin 19. Through holes are provided on the stop plate 7 and the stripping plate 6 for the stripping ejector pin 19 to pass through. A stripping insert 21 is provided on the stripping plate 6 and is matched with the stripping ejector pin 19 inside the through hole. Oil supply holes for feeding oil to the tapping area are provided on both the stripping plate 6 and the lower template 5 to play a lubricating role. When the product is strongly pressed between the stripping plate 6 and the lower template 5, the stripping ejector pin 19 is pushed upward by the product, thereby compressing the second stripping spring 18. After the stamping and tapping are completed, the upper die base 2 is moved upward, and the second stripping spring 18 rebounds and resets to make the stripping ejector pin 19 rebound and reset to push the product, preventing the product from sticking to the stripping plate 6 and moving upward with the upper die base 2. When it is moved upward to a certain extent, the stop plate 7 is separated from the upper die bearing block 20, and the first stripping spring 11 rebounds and resets, thereby enabling the tapping pin 14 to be removed from the product, facilitating the removal of the product.

[0022] The principle of the present utility model

[0023] During use, the product to be stamped and tapped is placed on the lower template 5, and the upper die base 2 is moved downward toward the lower die base 1 until the stripping plate 6 is closely attached to the top of the product, thereby enabling stamping of the product. During the downward movement of the stripping plate 6, the screw 10 can be moved downward, thereby causing one side of the rotating slider 9 to move downward, compressing the first stripping spring 11. The other side of the rotating slider 9 moves upward to drive the support block 12, the tapping pin fixing block 13, and the tapping pin 14 to move downward toward the lower die base 1, thereby enabling the tapping operation on the product while strongly pressing the product between the stripping plate 6 and the lower template 5. Compared with the traditional method of first using a stamping machine for stamping and then using a tapping machine for tapping, it is more time-saving and labor-saving, and there is no need for secondary alignment of the tapping position, with high positioning accuracy. The combination of stamping and tapping effectively improves the production efficiency.

[0024] After the stamping and tapping are completed, the upper die base 2 is moved upward. The stripping structure 3 is used to prevent the product from sticking to the stripping plate 6 and moving upward with the upper die base 2. When it is moved upward to a certain extent, the stop plate 7 is separated from the upper die bearing block 20, and the first stripping spring 11 rebounds and resets, thereby enabling the tapping pin 14 to be removed from the product, facilitating the removal of the product.

[0025] The above description has been made on the present utility model and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design, without creative efforts, structural manners and embodiments similar to the technical solution without departing from the purpose of the creation of the present utility model, they shall fall within the protection scope of the present utility model.
