[0002] Currently, auto parts are widely used in the automotive industry. With the development of mold manufacturing technology, auto parts can achieve the advantages of fast molding, batch production, and high processing precision. However, during the stamping process of auto parts, due to the excessive punching force on the stamping machine, the parts still fit tightly to the mold after stamping. This makes it difficult for workers to unload the parts in time, which is time-consuming and labor-intensive, thus affecting the work efficiency of product processing.

[0003] Patent announcement number CN215746033U discloses a metal stamping stripping structure, which relates to the field of demoulding technology. Specifically, it is a metal stamping stripping structure, including an upper die and a lower die. The upper die includes an upper forming die set at the bottom of the upper die and two swing hooks installed on both sides of the upper die. The metal stamping stripping structure is directly provided with a swing hook on the upper die and a stripping plate on the lower die. During stripping, the swing hook hooks hook the stripping plate and then move upward with the upper die to push the hardware placed on the lower forming punch upward to complete the stripping. However, the stripping mechanism has poor stability when implementing the hardware stripping process, and the hardware is easy to fall off. Utility Model Content

[0009] A demoulding assembly installed in the groove for ejecting the hardware, comprising a connecting seat installed in the groove and an ejection plate connected to the connecting seat via a telescopic ejection member;

[0010] an upper die base connected to the lower die base;

[0011] An upper die frame mounted on the lower surface of the upper die base and movable up and down;

[0012] And a punching head connected to the upper mold frame is used to punch the hardware and apply downward pressure to the pop-up plate. After the punching is completed, the pop-up plate automatically pops out to complete the demoulding of the hardware.

[0013] Furthermore, the telescopic pop-up member includes a plurality of first telescopic rods and a first spring arranged at the top end of the connecting seat, and the first spring is sleeved inside the first telescopic rod.

[0014] Furthermore, the side wall of the connecting seat is provided with a sliding groove; the telescopic pop-up member also includes a slider having one end slidably connected to the sliding groove and the other end fixedly connected to the pop-up plate.

[0015] Furthermore, the slide groove is a straight slide groove.

[0016] Furthermore, the side wall of the slider is provided with a travel groove, and the travel groove is provided with a limit slider that moves along the trajectory of the travel groove. The limit slider is connected to one end of a connecting rod, and the other end of the connecting rod is rotatably connected to the hinge rod provided at the bottom of the slide groove.

[0017] Furthermore, the grooves are arranged side by side, the demoulding components are arranged side by side, and the limiting sliders of different demoulding components are connected by a travel rod, and the travel rod passes through the travel groove to drive the different demoulding components to move synchronously.

[0018] Furthermore, the travel groove includes a heart-shaped slide groove and an arc-shaped slide groove.

[0019] Furthermore, the edge of the upper surface of the lower mold frame is slidably connected to a first stripper plate frame and a second stripper plate frame which are symmetrically arranged.

[0020] Furthermore, the first stripper plate frame and the second stripper plate frame are C-shaped and connected at right angles. When the two are connected, their shape and size are consistent with the hardware.

[0021] Furthermore, first connecting blocks are provided on both sides of the first stripper plate frame, and second connecting blocks are provided on both sides of the second stripper plate frame, and the first connecting blocks and the second connecting blocks are connected by connecting pieces.

[0022] Furthermore, the connecting member includes a second telescopic rod and a second spring, and the second spring is sleeved in the second telescopic rod.

[0023] Furthermore, the side wall of the upper mold frame is provided with a first limiting rod and a second limiting rod for pushing the first connecting block and the second connecting block to move toward each other.

[0024] Furthermore, the first limiting rod and the second limiting rod are arranged above the first connecting block and the second connecting block.

[0025] Furthermore, the first limiting rod and the second limiting rod are arranged in an eight-shaped shape, and the distance between the upper ends of the first limiting rod and the second limiting rod is smaller than the distance between the lower ends.

[0026] Compared with the prior art, the utility model has the following advantages:

[0027] (1) The utility model provides a metal stamping and stripping device. When the punching head punches the metal part, the pop-up plate is subjected to a downward force and is located inside the groove. After the punching is completed, the punching head moves upward, and the metal part loses the downward pressure. The telescopic pop-up member controls the pop-up plate to automatically pop up, so that the metal part receives an upward force and is separated from the lower mold frame, achieving smooth demolding without manual unloading, thereby effectively improving the work efficiency of product processing.

[0028] (2) The utility model provides a metal stamping stripping device, wherein the telescopic ejection member includes a plurality of first telescopic rods and a first spring disposed at the top end of the connecting seat, wherein the first spring is sleeved within the first telescopic rod. The pressure exerted by the punch head on the metal stamping causes the first telescopic rods and the first spring to contract, generating an elastic force, and automatically ejecting upward after the stamping is completed. No other driving force components are required, resulting in a simple structure and easy operation.

[0029] (3) The hardware stamping and forming stripping device provided by the present invention, in addition to arranging a first telescopic rod and a first spring to control the pop-up of the pop-up plate, is also provided with a slide groove on the side wall of the connecting seat, and a slider that moves up and down along the slide groove is provided in the slide groove, and one end of the slider is connected to the pop-up plate. The slide groove and the slider can effectively limit the position of the pop-up plate when it pops up and make it move up and down, and the pop-up plate will not shake due to the elastic force of the spring, thereby affecting the demolding of the hardware, thereby improving the production efficiency of the product.

[0030] (4) The metal stamping and forming stripping device provided by the present invention has a heart-shaped or arc-shaped travel groove provided on the side wall of the slider. When the pop-up plate moves, the limit slider moves along the travel groove. On the one hand, the travel of the slider can be effectively controlled so that it is limited by the connecting rod and will not pop out too quickly, thereby limiting its pop-up speed to a certain extent. On the other hand, the position of the pop-up plate can be limited when the spring is compressed or extended so that it is stuck and will not pop out or retract when it fails.

[0031] (5) The hardware stamping and forming demoulding device provided by the present invention has limit sliders of different demoulding components connected by a travel rod, and the travel rod passes through the travel groove to drive the different demoulding components to move synchronously, so that the pop-up height of each pop-up plate is the same, and when one of the demoulding components fails, the other demoulding components can drive it to pop out together, thereby ensuring the demoulding of the hardware.

[0032] (6) The hardware stamping stripping device provided by the present invention is provided with a first stripper plate frame and a second stripper plate frame at the edge of the lower die frame. During stamping, the first stripper plate frame and the second stripper plate frame are moved closer to each other under the action of the first limiting rod and the second limiting rod, thereby limiting the position of the hardware and making the hardware firmly positioned on the lower die frame when the punching head is stamping. The hardware will not be deflected due to the pressure of the punching head, thereby resulting in a low product qualification rate. After the punching head completes the stamping, the first limiting rod and the second limiting rod move upward, and the first stripper plate frame and the second stripper plate frame move away from each other, thereby preventing the hardware from being restricted by them when it pops up, thereby affecting its demolding.

[0077] In this embodiment, the sliding groove 311 is a straight sliding groove.

[0078] In this embodiment, the side wall of the slider 323 is provided with a travel groove 324, and the travel groove 324 is provided with a limit slider 325 that moves along the trajectory of the travel groove 324. The limit slider 325 is connected to one end of the connecting rod 326, and the other end of the connecting rod 326 is rotatably connected to the hinge rod 327 provided at the bottom of the slide groove 311.

[0079] In this embodiment, the grooves 21 are arranged side by side, the demoulding components 3 are arranged side by side, and the limiting sliders 325 of different demoulding components 3 are connected by a travel rod 328. The travel rod 328 passes through the travel groove 324 to drive different demoulding components 3 to move synchronously.

[0080] In this embodiment, the travel groove 324 is a heart-shaped groove.

[0081] In this embodiment, the edge of the upper surface of the lower mold frame 2 is slidably connected to a first stripper plate frame 22 and a second stripper plate frame 23 that are symmetrically arranged.

[0082] In this embodiment, the first stripper plate frame 22 and the second stripper plate frame 23 are C-shaped and connected at right angles. When the two are connected, their shape and size are consistent with the hardware 7.

[0083] In this embodiment, first connecting blocks 24 are provided on both sides of the first stripper plate frame 22 , and second connecting blocks 25 are provided on both sides of the second stripper plate frame 23 . The first connecting block 24 and the second connecting block 25 are connected by a connecting piece 26 .

[0084] In this embodiment, the connecting member 26 includes a second telescopic rod 261 and a second spring 262 , and the second spring 262 is sleeved inside the second telescopic rod 261 .

[0085] In this embodiment, the side walls of the upper mold frame 5 are provided with a first limiting rod 51 and a second limiting rod 52 for pushing the first connecting block 24 and the second connecting block 25 to move toward each other.

[0086] In this embodiment, the first limiting rod 51 and the second limiting rod 52 are disposed above the first connecting block 24 and the second connecting block 25 .

[0087] In this embodiment, the first limiting rod 51 and the second limiting rod 52 are arranged in an eight-shaped shape, and the distance between the upper ends of the first limiting rod 51 and the second limiting rod 52 is smaller than the distance between the lower ends.

[0088] The working process of the metal stamping stripping device is as follows:

[0089] In the initial state, the hardware 7 is placed on the lower die frame 2, the limiting slider 325 is located at the lowest point in the travel groove 324, and the pop-up plate 33 is higher than the groove 21. The upper die frame 5 and the punch head 6 move downward, the first limiting rod 51 abuts the side wall of the first connecting block 24, and the second limiting rod 52 abuts the side wall of the second connecting block 25. Since the first limiting rod 51 and the second limiting rod 52 are arranged in an eight-shaped shape, the distance between the upper ends of the first limiting rod 51 and the second limiting rod 52 is smaller than the distance between the lower ends. The first limiting rod 51 and the second limiting rod 52 bring the first connecting block 24 and the second connecting block 25 closer to each other, causing the second telescopic rod 261 and the second spring 262 to contract, thereby causing the first stripper frame 22 and the second stripper frame 23 to slide in a direction closer to each other, forming a stripper, thereby abutting the outer edge of the hardware 7 to prevent it from deflecting and assisting the stamping process.

[0090] At this time, the hardware 7 presses the pop-up plate 33 downward, and the pop-up plate 33 drives the slider 323 downward. With the cooperation of the hinge rod 327, the connecting rod 326 swings and drives the limit slider 325 to slide to the highest point in the travel groove 324 (a heart-shaped groove in this embodiment). At the same time, the first telescopic rod 321 and the first spring 322 shorten, and the pop-up plate 33 returns to the groove 21 and is flush with the plane of the lower mold frame 2. The punch head 6 punches the hardware 7.

[0091] After stamping is complete, the punch head 6 moves upward, removing the downward pressure on the hardware component 7. The first telescopic rod 321 and first spring 322 extend, ejecting the pop-up plate 33. Simultaneously, the connecting rod 326 swings, driving the limiting slider 325 to slide to the recessed position at the bottom of the travel slot 324, raising the pop-up plate 33 above the recess 21, thereby demolding the hardware component 7. As the punch head 6 moves upward, the first and second limiting rods 51 and 52 move upward, releasing the first and second connecting blocks 24 and 25. Under the action of the second telescopic rod 261 and second spring 262, the first and second connecting blocks 24 and 25 move away from each other, driving the first and second stripper plate frames 22 and 23 to slide away from each other, releasing the hardware component 7 and facilitating successful demolding.

[0092] The above description of the embodiments is intended to facilitate understanding and use of the utility model by those skilled in the art. Those skilled in the art will readily be able to make various modifications to these embodiments and apply the general principles described herein to other embodiments without requiring inventive effort. Therefore, the utility model is not limited to the above-described embodiments. Improvements and modifications made by those skilled in the art based on the disclosure of this utility model without departing from the scope of this utility model should be within the scope of protection of this utility model.
