Description

Technical Field

[0001] This utility model belongs to the field of stamping die related equipment, and in particular relates to an automatic pushing device for a stamping die and a stamping die equipment. Background Technology

[0002] In modern manufacturing, compression molding equipment is widely used in many fields. Compression molding equipment can be used to shape workpieces into the desired shape, or to form the desired shape through injection molding.

[0003] In some existing molding equipment, a conveyor belt is used to transfer the workpiece to be molded to the molding mechanism for pressing. The conveyor belt is generally driven by a linear motor, servo motor, or similar means to move the workpiece to the molding mechanism and stop it. After molding is completed, the conveyor belt is restarted and the molded workpiece is sent to the next process.

[0004] While automated mass production of molds can be achieved through motor drive in some low-cost molding equipment, the high-precision and high-cost motor control method not only results in excessively high equipment costs and a very long debugging period, but also a high degree of equipment complexity, which is not conducive to cost reduction and efficiency improvement. Utility Model Content

[0005] To address the aforementioned problems, this invention proposes an automatic pusher for the molding belt and a molding equipment. By replacing the traditional motor-driven belt with a belt driven by the combined action of the molding structure, the use of a drive motor is reduced, thereby decreasing production costs, simplifying equipment complexity, and reducing debugging time.

[0006] In a first aspect, this utility model proposes an automatic pushing device for a compression molding belt, comprising:

[0007] The conveyor belt has multiple through holes along the first direction;

[0008] A molding mechanism is mounted on a conveyor belt and includes an upper mold assembly and a lower mold assembly; the upper mold assembly is provided with a first inclined surface;

[0009] A pushing mechanism includes a first pushing component and an elastic component; the first pushing component is provided with a first protrusion having a second inclined surface, the first protrusion can extend into a through hole, and the elastic component is provided on the first pushing component to reset the first pushing component.

[0010] When the mold closing mechanism closes the mold, the upper mold assembly presses the first protrusion away from the conveyor belt, the first inclined surface abuts against the second inclined surface and pushes the first protrusion to move in the second direction opposite to the first direction, so that the first protrusion extends into the previous through hole. After the mold opening mechanism opens the mold, the elastic component pulls the first pushing component to reset and causes the conveyor belt to move in the first direction.

[0011] A conveyor belt with multiple through holes along a first direction is provided on an automatic pressing belt pushing device. A pressing mechanism, mounted on the conveyor belt, includes an upper mold assembly and a lower mold assembly. The upper mold assembly has a first inclined surface. A pushing mechanism includes a first pushing component and an elastic component. The first pushing component has a first protrusion with a second inclined surface, which can extend into the through holes. The elastic component is mounted on the first pushing component to reset it. When the pressing mechanism closes, the upper mold assembly presses the first protrusion away from the conveyor belt. The first and second inclined surfaces abut against each other, pushing the first protrusion in a second direction opposite to the first direction, allowing it to extend into the previous through hole. After the pressing mechanism opens, the elastic component pulls the first pushing component back to its original position, causing the conveyor belt to move in the first direction. This structure replaces the motor-driven conveyor belt movement, simplifying the equipment, reducing debugging time, and lowering equipment costs.

[0012] In some embodiments, the pushing mechanism further includes a second pushing component, wherein the first pushing component and the second pushing component are arranged sequentially in a first direction, and the second pushing component includes a second protrusion that can be deeply disposed in a through hole.

[0013] The second push component is used only for limiting and stabilizing the movement of the conveyor belt.

[0014] In some embodiments, the ends of both the first protrusion and the second protrusion are provided with a third inclined surface, the inclined surface of the third inclined surface facing the second direction.

[0015] The third bevel allows the first and second protrusions to detach more easily and penetrate deeper into the through hole.

[0016] In some embodiments, the bottom end of the third inclined surface is provided with an arc surface, and the third inclined surface is located on the side of the conveyor belt entrance where the first protrusion and the second protrusion face each other.

[0017] The curved surface prevents the edges of the first and second protrusions from rubbing and wearing against the edge of the through hole when disengaging and penetrating it.

[0018] In some embodiments, the first pushing component includes a slide rail, a first base, and a first elastic member; the slide rail is disposed at the bottom of the conveyor belt and is parallel to the conveyor belt; the first base is disposed on the slide rail and slides; the first base is provided with a first elastic groove; the first elastic member is disposed in the first elastic groove; and a first protrusion is disposed at the opening of the first elastic groove and connected to the first elastic member, so that the first protrusion extends and retracts at the opening of the first elastic groove.

[0019] The first protrusion structure, which can be elastically raised and lowered, allows the first protrusion to shrink and squeeze the first elastic element during pressing, and to elastically extend and penetrate into the through hole during mold opening, and the displacement of the first protrusion is achieved by the slide rail.

[0020] In some embodiments, the second pushing component includes a second base and a second elastic member; the second base is disposed at the bottom of the conveyor belt, a second elastic groove is provided inside the second base, the second elastic member is disposed inside the second elastic groove, and a second protrusion is disposed at the opening of the second elastic groove and connected to the second elastic member, so that the second protrusion can extend and retract at the opening of the second elastic groove.

[0021] The second protrusion structure, which can be elastically raised and lowered, allows the second protrusion to shrink and squeeze the second elastic element during pressing, and to elastically extend and penetrate into the through hole during mold opening.

[0022] In some embodiments, the elastic component includes a third elastic element disposed on one side of the conveyor belt and arranged parallel to the conveyor belt.

[0023] The first protrusion is reset by a third elastic element.

[0024] In some embodiments, the upper mold assembly is provided with a first extension, which is perpendicular to the surface of the conveyor belt and is provided on both sides of the conveyor belt. A first inclined surface is provided at the end of the first extension. The first push assembly is provided with a second extension, which is provided on the second extension. The inclined surfaces of the first and second inclined surfaces are arranged opposite to each other.

[0025] With the first extension and the second extension on both sides of the conveyor belt, when the mold is closed, the first extension causes the first protrusion to displace by extrusion and stretches the elastic component, thereby causing the first protrusion to reset and the conveyor belt to move when the mold is opened.

[0026] In some embodiments, a station interval is provided between the through holes, and the station interval is the same as the width of the first extension.

[0027] By adjusting the station interval and the width of the first extension, the travel of the conveyor belt is equal to the length of the station interval each time the first protrusion resets.

[0028] Secondly, this utility model also proposes a molding equipment, including an automatic molding belt pushing device, a machine base, a driving device, a feeding device, and a discharging device as described in any of the first aspects; the automatic molding belt pushing device is set on the machine base, the driving device drives the molding mechanism to close the mold, the feeding device is set at the entrance of the conveyor belt, and the discharging device is set at the exit of the conveyor belt.

[0029] The beneficial effects of this utility model of an automatic pushing device for pressing molds and pressing equipment are:

A pressing mechanism, mounted on the conveyor belt, includes an upper mold assembly and a lower mold assembly. The upper mold assembly has a first inclined surface. A pushing mechanism includes a first pushing component and an elastic component. The first pushing component has a first protrusion with a second inclined surface, which can extend into the through holes. The elastic component is mounted on the first pushing component to reset it. When the pressing mechanism closes, the upper mold assembly presses the first protrusion away from the conveyor belt. The first and second inclined surfaces abut against each other, pushing the first protrusion in a second direction opposite to the first direction, allowing it to extend into the previous through hole. After the pressing mechanism opens, the elastic component pulls the first pushing component back to its original position, causing the conveyor belt to move in the first direction. This structure replaces the motor-driven conveyor belt movement, simplifying the equipment, reducing debugging time, and lowering equipment costs. Attached Figure Description

[0051] Example 1:

[0052] like Figure 1 As shown, this embodiment proposes an automatic pushing device for a molding belt, comprising:

[0053] The conveyor belt 11 has multiple through holes 111 along the first direction X1;

[0054] The molding mechanism is mounted on the conveyor belt 11 and includes an upper mold assembly 21 and a lower mold assembly 22; the upper mold assembly 21 is provided with a first inclined surface 211;

[0055] The pushing mechanism includes a first pushing component 31 and an elastic component 33; the first pushing component 31 is provided with a first protrusion 311 having a second inclined surface, the first protrusion 311 can extend into the through hole 111, and the elastic component 33 is provided on the first pushing component 31 to reset the first pushing component 31.

[0056] When the mold closing mechanism is engaged, the upper mold assembly 21 presses the first protrusion 311 away from the conveyor belt 11. The first inclined surface 211 abuts against the second inclined surface and pushes the first protrusion 311 to move in the second direction X2, which is opposite to the first direction X1, so that the first protrusion 311 extends into the previous through hole 111. After the mold opening mechanism is engaged, the elastic component 33 pulls the first pushing component 31 to reset and moves the conveyor belt 11 in the first direction X1.

[0057] Specifically, the conveyor belt 11 is provided with multiple through holes 111 along the first direction X1, which is the transport direction of the conveyor belt 11, typically from the inlet to the outlet of the conveyor belt 11. The through holes 111 are spaced apart and can generally be located on one side or both sides of the conveyor belt 11. The through holes 111 need to avoid the position of the pressing mold to avoid affecting the pressing mold. At the same time, a pressing mold mechanism is provided on the conveyor belt 11. The pressing mold mechanism typically includes an upper mold assembly 21 and a lower mold assembly 22. The upper mold assembly 21 may have an upper template, and the lower mold assembly 22 may have a lower template. The upper and lower templates are provided with pressing grooves to achieve alignment and pressing during mold closing. The conveyor belt 11 needs to pass through the pressing grooves to transport the workpiece to be pressed. The upper mold assembly 21 is provided with a first inclined surface 211, which typically avoids the pressing grooves and can be located on the periphery of the pressing grooves. Its main purpose is to achieve interaction with the pushing mechanism. The pushing mechanism includes a first pushing component 31 and an elastic element. The first protrusion 311 of the first pushing component 31 extends into the through hole 111. The first protrusion 311 has a second inclined surface that abuts against the first inclined surface 211. The second inclined surface can move relative to the first inclined surface 211 with the first pushing component 31. The first inclined surface 211 is typically fixed and does not move with pressing. An elastic element 33, which can be a spring structure, is also provided on the first pushing component 31. It should be noted that the first inclined surface 211 and the second inclined surface are positioned opposite each other. During mold closing, the first inclined surface 211 and the second inclined surface maintain a certain positional overlap, and the length of the first inclined surface 211 is typically greater than the length of the second inclined surface. More specifically, as shown in the side view of the device, when the first inclined surface 211 and the second inclined surface interact, with the first inclined surface 211 fixed, the second inclined surface can move along the second direction X2. The specific flow of this mechanism is as follows:

[0058] In the normal position, the elastic structure is inactive, and the first protrusion 311 extends into the through hole 111, which can be referred to as the first through hole 111. During mold closing, the upper mold mechanism presses the first protrusion 311 below the through hole 111, and the first inclined surface 211 and the second inclined surface abut against each other. As the upper mold assembly 21 and the lower mold assembly 22 gradually close, the contact area of ​​the first inclined surface 211 and the second inclined surface gradually increases. Since the first inclined surface 211 is in a fixed position, the movable second inclined surface, which overlaps in position, will be pushed in the second direction X2, pulling the elastic component 33 to elongate and accumulate elastic potential energy. This causes the first protrusion 311 to move in the second direction X2 at the bottom of the conveyor belt 11 and move to the previous through hole 111, which can be referred to as the second through hole 111. The second through hole 111 and the first through hole 111 are arranged sequentially and adjacent to each other in the first direction X1 of the conveyor belt 11. The position of the second through hole 111 is relatively forward relative to the position of the first through hole 111 in the first direction X1. When the mold is fully closed, the first protrusion 311 is displaced to the second through hole 111. After the mold is opened, the first protrusion 311 rises to the second through hole 111. At this time, the elastic component 33 pulls the first protrusion 311 back to its original position in the first through hole 111. When the first protrusion 311, which is engaged in the through hole 111, moves to the position of the first through hole 111, the conveyor belt 11 also moves relative to its original position in the first direction X1. That is, the original position of the first through hole 111 is now the second through hole 111, and the above process is repeated to achieve pressing movement. Furthermore, a moving groove can be provided in the lower mold assembly 22, and the first inclined surface 211 and the second inclined surface abut in the moving groove, causing the second inclined surface to move.

[0059] A conveyor belt 11 is provided on the automatic pressing belt pushing device, and multiple through holes 111 are provided along the first direction X1; a pressing mechanism is provided on the conveyor belt 11, including an upper mold assembly 21 and a lower mold assembly 22; the upper mold assembly 21 is provided with a first inclined surface 211; a pushing mechanism includes a first pushing assembly 31 and an elastic assembly 33; the first pushing assembly 31 is provided with a first protrusion 311 having a second inclined surface, the first protrusion 311 can extend into the through hole 111, and the elastic assembly 33 is provided in the first... A push assembly 31 is used to reset the first push assembly 31; so that when the mold closing mechanism closes the mold, the upper mold assembly 21 presses the first protrusion 311 away from the conveyor belt 11, the first inclined surface 211 abuts against the second inclined surface and pushes the first protrusion 311 to move in the second direction X2 opposite to the first direction X1, so that the first protrusion 311 extends into the next through hole 111. After the mold opening mechanism opens the mold, the elastic component 33 pulls the first push assembly 31 back to its original position and moves the conveyor belt 11 in the first direction X1. This structure replaces the motor-driven movement of the conveyor belt 11, thereby simplifying the equipment, reducing debugging time, and lowering equipment costs.

[0060] Example 2:

[0061] Please refer to this again. Figure 1 Combining such Figures 2-3 As shown, this embodiment further explains and optimizes the structure proposed in Embodiment 1:

[0062] In some embodiments, the pushing mechanism further includes a second pushing component 32. The first pushing component 31 and the second pushing component 32 are sequentially arranged in a first direction X1. The second pushing component 32 includes a second protrusion 321, which can be deeply disposed in the through hole 111. Specifically, a second pushing component 32 is also provided. The second pushing component 32 can have the same structure as the first pushing component 31, except that the second pushing component 32 is immovable and can be fixed in a predetermined position by screws, more specifically, at the position of the next through hole 111 in the first direction X1 from the position of the first protrusion 311. The second pushing component 32 can stabilize the movement of the conveyor belt 11. It should be noted that, in this approach, to prevent the second pushing component 32 from jamming the conveyor belt 11 and preventing it from moving when the first pushing component 31 pulls the conveyor belt 11 in the first direction X1 after mold opening, a delayed lifting structure is required, such as a small motor lifting mechanism. Alternatively, when the first pushing component 31 pulls the conveyor belt 11 in the first direction X1, the second pushing component 32 can disengage from the current through hole 111 and move to the next through hole 111 above the second protrusion 321, at which point the second protrusion 321 extends into the through hole 111. The second pushing component 32 is used only for limiting and stabilizing the movement of the conveyor belt 11.

[0063] In view of the above structure, this embodiment proposes a preferred implementation method. In some embodiments, the ends of the first protrusion 311 and the second protrusion 321 are provided with a third inclined surface 3111, and the third inclined surface 3111 is provided on the side of the first protrusion 311 and the second protrusion 321 facing the inlet of the conveyor belt 11. Specifically, both the first protrusion 311 and the second protrusion 321 are provided with a third inclined surface 3111. After the mold is opened, when the first protrusion 311 pushes the conveyor belt 11 to move in the first direction X1, the other side of the first protrusion 311 and the third inclined surface 3111 abut against the wall of the through hole 111 and are pulled. At this time, the first protrusion 311 is stuck in the through hole 111 and cannot be removed. The second protrusion 321 is stationary relative to the conveyor belt 11. The third inclined surface 3111 of the second protrusion 321 will abut against the wall of the through hole 111. When moving, when the height of the conveyor belt 11 remains unchanged, the third inclined surface 3111 will be subjected to the pressure of the side wall of the through hole 111 and decomposed into a downward force, causing the second protrusion 321 to move downward and disengage from the through hole 111. After the first pushing component 31 stops, the first through hole 111 of the second pushing component 32 comes above the second protrusion 321, at which point the second protrusion 321 can be fixed inside the through hole 111. It should be noted that after molding, a through hole 111 is left between the first pushing component 31 and the second pushing component 32, so that when the first pushing component 31 resets, the left through hole 111 comes into contact with the second pushing component 32 and is fixed by the second protrusion 321. The third inclined surface 3111 makes it easier for the first protrusion 311 and the second protrusion 321 to detach and penetrate into the through hole 111.

[0064] In some preferred embodiments, the bottom end of the third inclined surface 3111 is provided with an arc surface 3112, and the third inclined surface 3111 is provided on the side of the first protrusion 311 and the second protrusion 321 facing the inlet of the conveyor belt 11. The arc surface 3112 can avoid friction and wear of the edges of the first protrusion 311 and the second protrusion 321 on the edge of the through hole 111 when disengaging from and penetrating the through hole 111.

[0065] In some embodiments, the first pushing component 31 includes a slide rail 312, a first base 313, and a first elastic member 314. The slide rail 312 is disposed at the bottom of the conveyor belt 11 and is parallel to the conveyor belt 11. The first base 313 is disposed on the slide rail 312 and slides on it. A first elastic groove is provided in the first base 313. The first elastic member 314 is disposed in the first elastic groove. A first protrusion 311 is disposed at the opening of the first elastic groove and is connected to the first elastic member 314, so that the first protrusion 311 can extend and retract at the opening of the first elastic groove. Specifically, the rail is disposed at the bottom of the conveyor belt 11, and the slide rail 312 is parallel to the conveyor belt 11. More specifically, the slide rail 312 is disposed on one side of the mold closing groove. It can be that a moving groove is provided on the lower mold component 22, and the slide rail 312 is positioned relative to the moving groove. The first pushing component 31 further moves on the slide rail 312 within the moving groove. The conveyor belt 11 has a portion of a through hole 111 passing above the moving groove to achieve the function in Embodiment 1. The first elastic element 314 can be a spring, and it automatically extends and retracts to move up and down within the through hole 111. The elastically movable first protrusion 311 structure allows the first protrusion 311 to contract and compress the first elastic element 314 during pressing, and to elastically extend and penetrate into the through hole 111 during mold opening. The displacement of the first protrusion 311 is achieved via the slide rail 312.

[0066] In some embodiments, the second pushing component 32 includes a second base 322 and a second elastic member 323. The second base 322 is disposed at the bottom of the conveyor belt 11, and a second elastic groove is provided inside the second base 322. The second elastic member 323 is disposed inside the second elastic groove, and a second protrusion 321 is disposed at the opening of the second elastic groove and connected to the second elastic member 323, so that the second protrusion 321 can extend and retract at the opening of the second elastic groove. The structure of the second pushing component 32 can be the same as that of the first pushing component 31, and will not be described in detail here. The only difference is that the second pushing component 32 does not need to move, so there is no need for the slide rail 312 structure, and it only needs to be fixed below the conveyor belt 11. Through the elastically liftable second protrusion 321 structure, the second protrusion 321 shrinks and squeezes the second elastic member 323 during pressing, and elastically extends and penetrates into the through hole 111 during mold opening.

[0067] In some embodiments, the elastic component 33 includes a third elastic element 331, which is disposed on one side of the conveyor belt 11 and parallel to the conveyor belt 11. Specifically, the third elastic element 331 can be a spring, and the structure of the spring can realize the reset of the first pushing component 31. When the spring is set to its initial position, the third elastic element 331 is in a non-stretched state. The third elastic element 331 is used to reset the first protrusion 311.

[0068] In some embodiments, the upper mold assembly 21 is provided with a first extension 212, which is perpendicular to the surface of the conveyor belt 11 and is located on both sides of the conveyor belt 11. A first inclined surface 211 is located at the end of the first extension 212. The first push assembly 31 is provided with a second extension 315, which extends to one side of the conveyor belt 11. A second inclined surface is located on the second extension 315, and the inclined surfaces of the first and second inclined surfaces are arranged opposite to each other. Specifically, the first extension 212 extends perpendicular to the surface of the conveyor belt 11 and is located on both sides of the conveyor belt 11, but not at the location of the middle pressing groove of the pressing mechanism. The second push assembly 32 is provided with a second extension 315 so that the second inclined surface is aligned with the first inclined surface 211. The first extension 212 and the second extension 315 are located on both sides of the conveyor belt 11, so that when the mold is closed, the first extension 212 causes the first protrusion 311 to displace by compression, and the elastic component 33 is stretched, so that when the mold is opened, the first protrusion 311 is reset and the conveyor belt 11 is moved.

[0069] In some embodiments, a station interval Y is provided between the through holes 111, and the station interval Y is the same as the width of the first extension 212. Specifically, when the first inclined surface 211 and the second inclined surface are aligned, the second inclined surface is forced to move in the second direction X2, and the stroke of the movement is the width of the first extension 212 (with a rectangular cross-section). In this way, the first protrusion 311 can be moved into the previous through hole 111. By using the station interval Y and the width of the first extension 212, the first protrusion 311 is reset so that the stroke of the conveyor belt 11 is the length of the station interval Y each time.
