Description

Technical Field

[0001] The utility model relates to the technical field of stamping equipment, and more specifically to a die-derived switching slider structure based on high-stroke stability. Background Art

[0002] As the automotive market's demand for various types of hybrid electric products continues to increase, new demands have arisen for automotive covers to be designed with charging ports in places such as fenders or side panels. In order to meet the same mold production of gasoline vehicles, HEVs (without charging ports) and PHEVs (with charging ports) and reduce the cost of developing new molds during the early or late stages of product design, it is usually necessary to add a mechanism to switch between the two product derivatives to the mass production mold. However, the existing design cannot meet the new demand and there is a risk of failure, so a new switching mechanism needs to be developed.

[0003] The existing die-derived switching mechanism is only suitable for punching with a short stroke of 8-10mm, and cannot meet the stroke requirements of 10mm and above; the lack of forced return and safety limit functions leads to unstable and non-unique working insert states when the derived switching mechanism returns and resets; the lack of a structural derived state information module means that the automated production line cannot automatically determine whether the structure is in the correct state, resulting in inconsistent structural appearance (such as charging ports) of the products produced when abnormalities occur, resulting in serious waste of product scrapping and production line downtime costs, and the risk of product outflow due to poor quality. With the new demand for automotive products (such as charging ports, etc.), there is an urgent need for a structure with a high stroke and forced return safety limit.

[0004] The Chinese utility model application number CN202223108048.3 discloses a mold switching mechanism and a stamping mold, which can switch the working state of the mold, thereby realizing the production of parts in different states without developing two sets of molds, thereby reducing production costs; it includes a mounting seat, a pressure rod, a wedge block and a reset assembly, the pressure rod is detachably mounted on the mounting seat, one end of the pressure rod can be pressed by the movable mold of the mold when the mold is closed, so that the pressure rod can move in the vertical direction, the other end of the pressure rod is provided with a first inclined surface, the wedge block is fixedly connected to the core, the wedge block is provided with a second inclined surface, the first inclined surface is abutted against the second inclined surface, so that the wedge block moves in the horizontal direction when the pressure rod is pressed by the passive mold and moves in the vertical direction, and the reset assembly is configured to reset the pressure rod and the wedge block when the mold is separated.

[0005] In the above technical solution, although the switching mechanism has a compact structure, the switching stroke is small and cannot meet the switching requirements of a large stroke. It lacks forced return and safety limit functions, resulting in unstable and non-unique states of the pressure rod and the wedge block during return and reset, which can easily cause failure of the switching mechanism and poor processing, resulting in defective and waste products. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides a die-derived switching slider structure based on high stroke stability.

Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as limitations on this patent. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0025] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0026] Example 1

[0027] like Figure 2As shown, a mold-derived switching slider structure based on high-stroke stability includes a guide block 1, a working insert 2 and a slider 3; the working insert 2 and the slider 3 are both installed in the guide block 1, the working insert 2 and the guide block 1 are slidably connected in the vertical direction, and the slider 3 and the guide block 1 are slidably connected in the horizontal direction; the slider 3 is provided with a first abutting surface 31 and a second abutting surface 32, and the first abutting surface 31 and the second abutting surface 32 have a height difference; the upper surface of the working insert 2 can abut against the first abutting surface 31 or the second abutting surface 32, and a guide structure is provided between the working insert 2 and the slider 3. The mold-derived switching slider structure based on high-stroke stability is installed between the upper die and the pressure plate, and the punch is installed on the lower end surface of the working insert. The height of the first abutting surface 31 in the vertical direction is located above the second abutting surface 32. The working insert 2 is installed in the guide block 1, and the working insert 2 slides in the guide block 1 along the vertical direction. When the punch is not required to work during the stamping operation, the upper surface of the working insert 2 is switched to abut against the first abutting surface 31 of the slider 3. When the punch is required to work, the upper surface of the working insert 2 is switched to abut against the second abutting surface 32 of the slider. When the upper surface of the working insert 2 switches between abutting against the first abutting surface 31 and abutting against the second abutting surface 32 of the slider 1, there is a possibility that the working insert 2 and the slider 3 are separated, causing a failure of the switching mechanism. Therefore, a guide structure is provided between the working insert 2 and the slider 3, so that the relative movement between the working insert and the slider can only move along the guide structure, and there will be no problem of separation between the working insert and the slider.

[0028] like Figure 2 As shown, the guide structure includes a guide column 23 and a guide hole 34. The guide column 23 is arranged on the working insert 2, and the guide hole 34 is arranged on the slider 3. The guide column 23 is slidably connected with the guide hole 34. The working insert 2 and the slider 3 have two working states. When the working state is switched, the state of the working insert 2 is unstable and not unique, and it is easy for the working insert 2 and the slider 3 to separate and cause a malfunction. Therefore, it is necessary to set a guide structure so that the working insert 2 and the slider 3 move relative to each other along a determined path during switching. The guide structure includes a guide column 23 and a guide hole 34. The guide column 23 and the guide hole 34 are slidably connected, so that the working insert 2 and the slider 3 can only move relative to each other along the direction of the guide column 23 and the guide hole 34.

[0029] like Figure 2As shown, a first inclined wedge surface 33 is provided between the first abutting surface 31 and the second abutting surface 32, and a second inclined wedge surface 22 is provided on the working insert 2. The first inclined wedge surface 33 is parallel to the second inclined wedge surface 22, and the first inclined wedge surface 33 is connected to the second inclined wedge surface 22 by an inclined wedge. Due to the height difference between the first abutting surface 31 and the second abutting surface 32, if the first abutting surface 31 and the second abutting surface 32 are set as a vertical surface, the working insert 2 and the slider 3 will clash during the switching process, causing the switching to be stuck. In order to ensure the smooth switching process between the upper surface of the working insert 2 abutting against the first abutting surface 31 and the second abutting surface 32 of the slider 1, a first inclined wedge surface 33 is provided between the first abutting surface 31 and the second abutting surface 32, and a second inclined wedge surface 22 is provided on the working insert 2. The first inclined wedge surface 33 and the second inclined wedge surface 22 are slidably connected, so that the working insert 2 and the slider 3 form an inclined wedge connection. When switching between working states, the working insert 2 and the slider 3 move relative to each other along the inclined wedge surface without conflicting with each other, thus ensuring a smooth switching process.

[0030] like Figure 2 As shown, the central axis of the guide column 23 is parallel to the second inclined wedge surface 22, the guide column 23 is coaxial with the guide hole 34, the shape of the guide hole 34 matches the shape of the guide column 23, and the guide hole 34 runs through the slider 3. When switching between working states, the slider 3 moves horizontally, while the working insert 2 is restricted by the guide block 1 and cannot move in the horizontal direction. The first inclined wedge surface 33 on the slider 3 keeps in contact with the second inclined wedge surface 22 of the working insert 3. As the slider 3 moves, the first inclined wedge surface 33 and the second inclined wedge surface 22 contact at different heights, thereby driving the working insert 2 to move. In this process, with the slider 3 as the reference system, the working insert 2 slides along the first inclined wedge surface 33, and the second inclined wedge surface 22 is parallel to the first inclined wedge surface 33, so the movement direction of the working insert 2 relative to the slider 3 is parallel to the second inclined wedge surface 22. The function of the guide column 23 is to guide the relative movement between the working insert 2 and the slider 3, so the central axis of the guide column 23 is parallel to the second inclined wedge surface 22. The guide post 23 and the guide hole 34 are coaxial, ensuring that the two can be installed in a matching manner. The shape of the guide hole 34 matches the shape of the guide post 23. When the working insert 2 is about to be separated from the slider 2, the guide post 23 will conflict with the inner wall surface of the guide hole 34, thereby limiting the separation of the working insert 2 from the slider 2. The guide hole 34 is set as a through hole that penetrates the slider 3, which is convenient for processing the guide hole 34.

[0031] like Figure 2As shown, the upper surface of the guide block 1 is provided with a slide groove 11; the upper surface of the guide block 1 is also provided with a mounting hole 12, and the mounting hole 12 runs through the guide block 11; the slider 3 is installed on the slide groove 11 and is slidably connected to the slide groove 11; the working insert 2 is installed in the mounting hole 12 and is slidably connected to the mounting hole 12. The guide block 1 is not only used to limit the movement of the working insert 2, but also used to limit the movement of the slider 3. The guiding structures for the movement of the working insert 2 and the slider 3 are integrated on the guide block 1, so that the movement trajectories of the working insert 2 and the slider 3 can be determined by the guide block 1, ensuring the stability during work. During the switching of the working state, the slider 3 only needs to move linearly in the horizontal direction, so it is only necessary to open the slide groove 11 on the guide block 1, and the slider 3 can be slidably installed on the slide groove 11, so that the slider 3 can be limited to move only along the direction of the slide groove 11. The working insert 2 only needs to move linearly in the vertical direction, so it is only necessary to set a mounting hole 12 that passes through the guide block 1. The working insert 2 is installed in the mounting hole 12, which can limit the working insert 2 to move only along the direction of the mounting hole 12.

[0032] Example 2

[0033] This embodiment is similar to the above-mentioned embodiment 1, except that: Figure 2 As shown, a reset block 24 is provided on the upper end of the side of the working insert 2, a reset groove 13 is provided on the inner wall surface of the mounting hole 12, the reset groove 13 is aligned with the reset block 24, and a reset elastic member is installed between the reset block 24 and the bottom of the reset groove 13. In order to ensure the accuracy of the working state switching, it is necessary to ensure the close contact between the slider 3 and the working insert 2. Therefore, it is necessary to apply a reset force toward the slider 3 to the working insert 2 to overcome the gravity of the working insert 2 itself and the friction between the working insert 2 and other structures. The reset block 24 is provided on the side of the working insert 2, and the reset groove 13 is provided on the inner wall surface of the mounting hole 12, and a reset elastic member is provided between the bottom of the reset groove 13 and the reset block 24. The reset elastic member is in a compressed state, so it can continuously provide a reset force to keep the bottom of the reset groove 13 away from the reset block 24. Since the guide block 1 is immovable, the reset elastic member will push the working insert 2 to move in the direction of the slider 3 until the working insert 2 conflicts with the slider 3.

[0034] like Figure 2As shown, a limiting structure 4 is provided on the bottom surface of the slide groove 11 and the working insert 2. Since different working states are established according to which abutting surface of the working insert 2 and the slider 3 abut, the first abutting surface 31 and the second abutting surface 32 are at different positions in the horizontal direction. Therefore, the slider 3 moves to different positions in the horizontal direction, and the abutting surfaces abutting against the working insert 2 are different, and the working states are different. During the stamping process, the slider 3 will also be affected by the stamping force and may be displaced. And when the slider 3 is moved, it is easy to have an inaccurate moving position. In order to ensure that different working states can be accurately switched and no displacement occurs after switching, a limiting structure 4 needs to be provided on the bottom surface of the slide groove 11 and the working insert 2 to ensure that the slider 3 can stop at a certain position after sliding.

[0035] like Figure 2 As shown, the limiting structure 4 is a limiting hole, which is a blind hole. A limiting ball 41 and an elastic member 42 are installed in the limiting hole. The two ends of the elastic member 42 are connected to the limiting hole and the limiting ball 41 respectively. The bottom surface of the slider 3 is provided with a concave hole, and the concave hole matches the limiting ball 41. The position in the limiting structure 4 matches the concave hole. The limiting ball 41 is kept in contact with the lower surface of the slider 3 under the action of the elastic member 42. When the slider 3 slides to the position of the concave hole, the limiting ball is pushed into the concave hole, thereby realizing the positioning of the slider 3. There are multiple concave holes, which match different positioning positions of the slider 3 respectively. The limiting ball 41 is spherical, which, on the one hand, reduces the friction between the limiting ball 41 and the slider 3 when the slider 3 slides; on the other hand, when the working state mode is switched, the spherical limiting ball 41 provides a certain positioning force for the slider 3 and is easy to slide out of the concave hole of the slider 3, which is convenient for switching the working state.

[0036] like Figure 2 As shown, a self-lubricating guide plate 25 is installed on the side of the working insert 2, and the self-lubricating guide plate 25 is slidably connected with the guide hole 34. The surface of the self-lubricating guide plate 25 is smooth, which reduces the friction between the working insert 2 and the guide hole 34, and avoids the working insert 2 from sliding and jamming in the guide hole 34.

[0037] like Figure 2 As shown, a hook structure 35 for connecting to an external driving device is provided at one end of the slider 3. The slider 3 only needs to make a linear motion in the direction of the slide slot 11 to switch the working state. A hook structure is provided at one end of the slide slot 3 to connect to the external driving device, and the slider 3 is driven to make a linear motion, so that the working state switching process can be automated.

[0038] Example 3

[0039] This embodiment is similar to the above-mentioned embodiment 1, except that: Figure 1As shown, a Bluetooth module is also installed for detecting the position of the working insert 2. The punch is installed on the lower surface of the working insert 2, so whether the working insert 2 is switched in place can be used to directly determine whether the punch is in a preset working state. Since the high-stroke stable die-derived switching slider structure is installed between the upper die and the pressure plate, it is difficult to directly observe the working insert 2, so a Bluetooth module is set to detect the position of the working insert 2.

[0040] Obviously, the above embodiments of the utility model are only examples for clearly explaining the utility model, and are not intended to limit the implementation methods of the utility model. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to list all the implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should be included in the protection scope of the claims of the utility model.
