Description

Technical Field

[0001] This invention relates to the field of machining tooling technology, and more specifically, to a quick-change common tooling bracket. Background Technology

[0002] Tooling structures are essential in factory workshops, especially in the automotive parts manufacturing industry. For example, the manufacturing process of an automotive headliner requires tooling for fabric bonding, fabric edging, and plastic snap-fitting. Clearly, a single headliner component requires multiple different types of tooling structures to achieve the corresponding functional requirements.

[0003] Currently, most manufacturers use individual tooling for each step in the parts production process. Each type of tooling typically includes a tooling support and upper and lower molds. The tooling support essentially only provides fixation and support, resulting in significant resource waste and increased manufacturing costs. Furthermore, the numerous different types of tooling occupy considerable space. Therefore, reducing manufacturing costs and optimizing tooling structure are directions that need to be considered in technological improvements. Summary of the Invention

[0004] To overcome at least one of the defects in the prior art, the present invention provides a quick-change common tooling bracket, which can be used to install and adapt to different types of molds, reduce redundant and repetitive tooling brackets, and reduce production costs.

[0005] This invention provides a quick-change shared tooling bracket, including a frame body and a mold-changing trolley. The upper end of the frame body is connected to a vertically adjustable upper mounting plate. The upper mounting plate and / or the frame body are provided with a lifting drive mechanism for moving the upper mounting plate up and down. The upper mounting plate is provided with a quick-change mechanism for quickly disassembling and replacing different types of upper molds. The lower end of the frame body is connected to a lower mounting plate, which is provided with a positioning part for positioning different types of lower molds and multiple mold-locking mechanisms. A first connecting part is provided on one side of the frame body, and a second connecting part and a locking drive mechanism for engaging and disengaging the second connecting part from the first connecting part are provided on the mold-changing trolley. The frame body is also provided with a protective mechanism. During mold changing or maintenance, the support column of the protective mechanism is supported and limited at the lower end of the upper mounting plate. During operation, the support column can rotate to a retracted position so that the upper mounting plate can be raised and lowered normally.

[0006] Compared with the prior art, the quick-change common tooling bracket of the present invention has the following advantages:

[0007] Benxi Steel's quick-change common tooling bracket is a universal bracket suitable for installing various types of process molds. Specifically, the upper mounting plate is equipped with a quick-change structure, allowing for rapid assembly and disassembly of upper molds of different types when connected to the upper mounting plate. Similarly, the lower mounting plate is equipped with a positioning part and a mold-locking mechanism. When the lower mold of different types of molds is connected to the lower mounting plate, it is first positioned by the corresponding positioning part, and then locked in place by multiple mold-locking mechanisms. It is important to note that the positioning part and mold-locking mechanism are applicable to various types of molds in different industries, such as welding, coating, and pressing. The machine can accommodate various molds with different functions, such as mold closing and cooling, making it highly versatile. Furthermore, the frame body includes a protective mechanism with a support column that can rotate horizontally. During normal operation, the support column is retracted, allowing the upper mounting plate to rise and fall normally to close the upper and lower molds. When the mold needs maintenance or replacement, the upper mounting plate is typically raised to its highest position. At this time, the support column can rotate so that its upper end abuts against the lower surface of the upper mounting plate, preventing abnormal descent of the upper mounting plate due to a malfunction in the lifting drive mechanism and effectively ensuring the safety of operators.

[0008] Furthermore, the quick-change mechanism includes a plurality of first drive cylinders, and the upper mounting plate is provided with a plurality of communicating holes for the passage of a fixed insert plate preset on the upper mold. The plurality of first drive cylinders are mounted on the upper end face of the upper mounting plate and correspond to each of the communicating holes respectively. The driving end of each first drive cylinder is connected to a first locking pin that is inserted and positioned with the fixed insert plate.

[0009] As an improvement, the lower mounting plate is provided with fixed seats at both the front and rear ends on the left and right sides. Each fixed seat is provided with a limiting protrusion on the side near the lower mold, and each limiting protrusion is provided with a connecting hole. Each fixed seat is also provided with a second driving cylinder. The driving end of each second driving cylinder is connected with a second locking pin for inserting and engaging with the positioning holes preset on both sides of the lower mold through the connecting hole, so as to form the mold locking mechanism.

[0010] Furthermore, the lifting drive mechanism includes two guide racks, a dual-head motor, and two drive gears. The two guide racks are vertically connected to the two side walls of the frame body. The dual-head motor is connected to the upper end face of the upper mounting plate. The two drive gears are respectively connected to the output shaft of the dual-head motor, and the two drive gears mesh with the two guide racks respectively. A height positioning mechanism is also provided between the upper mounting plate and the frame body.

[0011] Furthermore, the height positioning mechanism includes two positioning racks, which are vertically connected to the two side walls of the frame body. Both ends of the upper mounting plate are connected to positioning drive cylinders, and the drive ends of the two positioning drive cylinders are connected to positioning protrusions that cooperate with the positioning racks.

[0012] Furthermore, the protective mechanism also includes a rotating shaft, the upper and lower ends of which are connected to the frame body via an upper fixing block and a lower fixing block, respectively. An upper positioning plate and a lower positioning plate are connected to the support column, and the ends of the upper and lower positioning plates away from the support column are slidably fitted onto the outside of the rotating shaft. An elastic element is provided between the lower positioning plate and the lower fixing block so that the support column always has an upward tendency. The upper positioning plate is provided with a positioning hole, and the upper fixing block is provided with a positioning pin. When the support column is in the storage position, the positioning pin is inserted and positioned in the positioning hole.

[0013] Furthermore, both the mold changing trolley and the lower mounting plate are provided with guide mechanisms for the lower mold to slide on the same horizontal plane. The guide mechanism includes at least one row of first guide wheels extending in the front-back direction, and two rows of second guide wheels arranged at the left and right ends of the frame body or the mold changing trolley and extending in the front-back direction. The lower end face and the left and right ends of the lower mold are respectively in rolling cooperation with the first guide wheels and the second guide wheels.

[0014] Furthermore, the first connecting part includes two locking blocks connected to the front walls of the left and right ends of the frame body. Each locking block has a vertically extending locking groove, and the front wall of the locking block has an insertion groove that communicates with the locking groove. The width of the insertion groove is smaller than the width of the locking groove. The rear walls of the left and right ends of the mold changing trolley are connected to locking plates that respectively cooperate with the two locking grooves. The lateral dimension of the locking plate is larger than its longitudinal dimension, the longitudinal dimension of the locking plate is smaller than the width of the insertion groove, and the lateral dimension is smaller than the width of the locking groove. When the locking plate extends into the locking groove through the insertion groove in a longitudinal position, the locking drive mechanism is used to drive the locking plate to a lateral position to achieve locking and limiting of the mold changing trolley and the frame body.

[0015] Furthermore, the locking drive mechanism includes two rotating shafts extending along the front-rear direction of the mold changing trolley. The two locking plates are respectively connected to the rear ends of the two rotating shafts, and a rotating handle is connected to the front end of each of the two rotating shafts. The rear side of the mold changing trolley is provided with a positioning pressure rod that is retractable in the front-rear direction on both sides of the two rotating shafts. When the locking plate is locked in the locking groove, the rear end of the positioning pressure rod is pressed against and limited on the outer wall of the locking block, so that the front side of the locking plate is pressed against and limited on the front side wall of the locking groove.

[0016] Furthermore, the positioning part includes two positioning protrusions connected to the rear end of the lower mounting plate, two positioning pins connected to the front end of the lower mounting plate, and two positioning drive cylinders for driving each positioning pin to move vertically. During mold changing, when the lower mold moves from front to back to the set position, the rear end of the lower mold abuts against the two positioning protrusions, and the two positioning drive cylinders drive the positioning pins to move upward until they are inserted into the preset positioning holes on the lower surface of the front end of the lower mold.

[0017] Other improvements and advantages of the invention will be set forth in the detailed description that follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the invention may be realized and obtained by means of the structures particularly pointed out in the description and the drawings. Attached Figure Description

[0025] First, those skilled in the art should understand that these embodiments are merely used to explain the technical principles of the embodiments of this application and are not intended to limit the scope of protection of the embodiments of this application. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

[0026] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "fixed" and "connected" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0027] In the description of this invention, it should be noted that the terms "upper end", "lower end", "front and back", "left and right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0028] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0029] See Figures 1-5 As shown in the figure, this application discloses a quick-change common tooling bracket, including a frame body 1 and a mold changing trolley 2, wherein the mold changing trolley 2 is detachably connected to the front side of the frame body 1 and is used to assist in changing different types of molds, mainly for assisting in the installation and disassembly of the lower mold.

[0030] Specifically, a vertically adjustable upper mounting plate 3 is connected to the upper end of the frame body 1. The upper mounting plate 3 and / or the frame body 1 are provided with a lifting drive mechanism for driving the upper mounting plate 3 to move up and down. The upper mounting plate 3 is provided with a quick-change mechanism for quickly disassembling and replacing different types of upper molds. The lower end of the frame body 1 is connected to a lower mounting plate 4. The lower mounting plate 4 is provided with a positioning part for positioning different types of lower molds and multiple locking mechanisms for locking and limiting the lower molds. A first connecting part is provided on one side of the frame body 1, and a second connecting part and a locking drive mechanism for driving the second connecting part to engage and disengage with the first connecting part are provided on the mold changing trolley 2. The frame body 1 is also provided with a protective mechanism. When changing molds or performing maintenance, the support column 5 of the protective mechanism is supported and limited at the lower end of the upper mounting plate 3. During operation, the support column 5 can be rotated to the storage position so that the upper mounting plate 3 can be raised and lowered normally.

[0031] In the above structure, an upper mounting plate 3 and a lower mounting plate 4 are respectively provided on the upper and lower sides of the frame body 1. The upper mounting plate 3 is used to install and position the upper mold, and the lower mounting plate 4 is used to install and position the lower mold. The upper mounting plate 3 is provided with a corresponding quick-change structure, so that the upper molds of different types of molds can be quickly disassembled and replaced when connected to the upper mounting plate 3 through the quick-change mechanism. Similarly, the lower mounting plate 4 is provided with a positioning part and a mold locking mechanism. When the lower molds of different types of molds are connected to the lower mounting plate 4, they are first positioned by the corresponding positioning part, and then the position is locked by multiple mold locking mechanisms. It is important to note that the positioning part and the mold locking mechanism can be applied to various types of molds in different industries. For example, it can perform various functions such as welding, coating, pressing, and cooling to create molds with strong versatility. In addition, the above structure also includes a protective mechanism on the frame body 1. This protective mechanism includes a support column 5, which can rotate horizontally. In normal operation, the support column 5 rotates to the retracted state, at which time the upper mounting plate 3 can be raised and lowered normally to achieve mold closing. When the mold needs to be repaired or replaced, the upper mounting plate 3 is generally raised to the highest point. At this time, the support column 5 can rotate so that its upper end abuts against the lower end surface of the upper mounting plate 3, preventing the upper mounting plate 3 from falling abnormally due to a failure of the lifting drive mechanism, thus ensuring the personal safety of the workers.

[0032] In this embodiment, specifically, the quick-change mechanism includes multiple first drive cylinders 6. The upper mounting plate 3 has multiple connecting holes 7 for a pre-set fixed insert plate on the upper mold to pass through. The multiple first drive cylinders 6 are mounted on the upper surface of the upper mounting plate 3 and correspond to each connecting hole 7. The driving end of each first drive cylinder 6 is connected to a first locking pin 8 for insertion and positioning with the fixed insert plate, thus achieving the connection and fixation of the upper mold. During mold changing, the upper mold is supported by a dedicated support component, and each first drive cylinder 6 moves in the opposite direction, causing each first locking pin 8 to disengage from the fixed insert plate. At this time, the upper mold first moves down a certain distance so that the fixed insert plate disengages from the connecting hole 7. Then, the upper mold can be moved horizontally to install and fix the new upper mold. In this structure, preferably, a positioning seat is provided on the upper end face of the upper mounting plate 3 at the position corresponding to each connecting hole 7. Each positioning seat has a sliding through hole. One end of each first locking pin 8 is connected to the driving end of the first driving cylinder 6, and the other end is slidably fitted in the sliding through hole. In addition, a horizontally arranged fixing plate is provided on the outer wall of each fixing seat 9. A sensor for detecting the first locking pin 8 is provided on the end of the fixing plate away from the positioning seat. That is, the sensor can identify whether each corresponding first locking pin 8 is extended to the working state, thereby ensuring that each fixing plate is inserted and positioned when the upper mold is connected, avoiding the situation where the upper mold connection is unstable due to the first locking pin 8 not extending normally. Furthermore, a controller is provided on the frame body 1, and each sensor is electrically connected to the controller. When a first locking pin 8 is detected not extending smoothly, the system can issue a warning.

[0033] Additionally, fixed seats 9 are provided at the front and rear ends of both sides of the lower mounting plate 4. Each fixed seat 9 is provided with a limiting protrusion 10 on the side near the lower mold, and each limiting protrusion 10 is provided with a connecting hole 7. Each fixed seat 9 is also provided with a second drive cylinder 11. The drive end of each second drive cylinder 11 is connected to a second locking pin 12 for inserting and engaging with the pre-set positioning holes on both sides of the lower mold through the connecting hole 7, so as to form a mold locking mechanism.

[0034] In this embodiment, to further ensure the installation stability and positional accuracy of the lower mold, the positioning part includes two positioning protrusions 34 connected to the rear end of the lower mounting plate 4 and spaced apart on the left and right, two positioning pins 35 connected to the front end of the lower mounting plate 4 and spaced apart on the left and right, and two positioning drive cylinders 17 for driving each positioning pin 35 to move vertically. When changing the mold, when the lower mold moves from front to back to the set position, the rear end of the lower mold abuts against the two positioning protrusions 34, and the two positioning drive cylinders 17 drive the positioning pins 35 to move upward until they are inserted into the preset positioning holes on the lower surface of the front end of the lower mold, thereby accurately defining the installation position of the lower mold. At the same time, combined with the insertion and locking of the four second locking pins 12 on the left and right sides of the lower mold, the structural stability of the lower mold after connection is effectively guaranteed.

[0035] Furthermore, in the above structure, see Appendix Figure 3 To facilitate the movement of the lower mold between the mold changing trolley 2 and the lower mounting plate 4 during mold changing, guide mechanisms for sliding of the lower mold and located on the same horizontal plane are provided on both the mold changing trolley 2 and the lower mounting plate 4. The guide mechanisms include at least one row of first guide wheels 25 extending in the front-to-back direction, and two rows of second guide wheels 26 located at the left and right ends of the frame body 1 or the mold changing trolley 2 and extending in the front-to-back direction. The lower end face and the left and right ends of the lower mold roll in cooperation with the first guide wheels 25 and the second guide wheels 26, respectively. (See appendix) Figure 1 , 3 The mold-changing trolley 2 is equipped with two rows of first guide wheels 25 and two rows of second guide wheels 26, while the lower mounting plate 4 is equipped with three rows of first guide wheels 25 and two rows of second guide wheels 26. The axes of the first guide wheels 25 extend in the left-right direction, and the axes of the second guide wheels 26 extend in the up-down direction. When the lower mold moves, its lower end face rolls with each of the first guide wheels 25, and its left and right outer walls roll with the two rows of second guide wheels 26, effectively reducing the frictional resistance of the lower mold during movement and facilitating mold changing. In this structure, each row of first guide wheels 25 or second guide wheels 26 includes multiple rollers spaced apart in the front-back direction.

[0036] In this embodiment, see Appendix Figure 2 The lifting drive mechanism includes two guide racks 13, a dual-head motor 14, and two drive gears 15. The two guide racks 13 are vertically connected to the two side walls of the frame body 1. The dual-head motor 14 is connected to the upper end face of the upper mounting plate 3. The two drive gears 15 are respectively connected to the output shaft of the dual-head motor 14, and the two drive gears 15 mesh with the two guide racks 13 respectively. The upper mounting plate 3 is lifted and lowered on the frame body 1 by the operation of the dual-head motor 14. On the other hand, in this structure, a height positioning mechanism is also provided between the upper mounting plate 3 and the frame body 1 so that the upper mounting plate 3 can be positioned at any height. Specifically, the height positioning mechanism includes two positioning racks 16, which are vertically connected to the two side walls of the frame body 1. Positioning drive cylinders 17 are connected to both ends of the upper mounting plate 3. The drive ends of the two positioning drive cylinders 17 are connected to positioning protrusions 18 that cooperate with the positioning racks 16. When the upper mounting plate 3 is positioned at a set height, the positioning protrusions at both ends of the upper mounting plate 3 engage in the corresponding grooves of the positioning racks 16. When the upper mounting plate 3 needs to be adjusted in height, the two positioning drive cylinders 17 retract, causing the two positioning protrusions 18 to disengage from their respective grooves. When the upper mounting plate 3 is adjusted to the required height, the two positioning protrusions 18 engage with their respective grooves again, thus defining the position of the upper mounting plate 3.

[0037] In the above structure, the upper mounting plate 3 and the lower mounting plate 4 are connected by four rectangular columns, and each of the four columns is connected to a vertically arranged linear slide rail. Slider blocks are connected to the four corners of the upper mounting plate 3, and the four sliders slide and engage with the corresponding linear slide rails to improve the stability of the upper mounting plate 3 moving up and down.

[0038] See appendix for further details. Figure 4 The protective mechanism in this embodiment includes two support columns 5, which are respectively set on the two end columns on the front side of the frame body 1. The following description takes the connection structure of the support column 5 on one side as an example. The protective mechanism also includes a rotating shaft 19. Upper fixing blocks 20 and lower fixing blocks 21 are provided on the two end columns at the front of the frame body 1. The upper and lower ends of the rotating shaft 19 are rotatably connected to the upper fixing blocks 20 and lower fixing blocks 21, respectively. An upper positioning plate 22 and a lower positioning plate 23 are connected to the support column 5, with the ends of the upper and lower positioning plates 22 and 23 slidably fitted onto the outside of the rotating shaft 19. An elastic element 24 is provided between the lower positioning plate 23 and the lower fixing block 21, ensuring that the support column 5 always tends to move upwards. The upper positioning plate 22 has a positioning hole, and the upper fixing block 20 has a positioning pin. When the support column 5 is in the retracted position, the positioning pin is inserted and positioned in the positioning hole under the action of the elastic element 24. When it is necessary to rotate the support column 5, the support column 5 must first be pressed down to compress the elastic element 24 until the positioning pin disengages from the positioning hole before the support column 5 can be rotated horizontally.

[0039] For others, see Appendix Figure 5The first connecting part includes two locking blocks 27 connected to the front walls of the left and right ends of the frame body 1. Each locking block 27 has a vertically extending locking groove 28, and the front wall of the locking block 27 has an insertion groove 29 that connects to the locking groove 28. The width of the insertion groove 29 is smaller than the width of the locking groove 28. The rear walls of the left and right ends of the mold changing trolley 2 are connected to locking pieces 30 that respectively cooperate with the two locking grooves 28. The lateral dimension of the locking piece 30 is larger than its longitudinal dimension. The longitudinal dimension of the locking piece 30 is smaller than the width of the insertion groove 29, and the lateral dimension is smaller than the width of the locking groove 28. That is, the locking piece 30 cannot pass through the insertion groove 29 and extend into the locking groove 28 in the lateral position. It needs to be rotated 90 degrees. When the longitudinal position corresponds to the insertion slot 29, the locking piece 30 can pass through the insertion slot 29 and enter the locking slot 28. Therefore, when the mold changing trolley 2 is connected and locked to the frame body 1, the locking piece 30 needs to be adjusted to the longitudinal position corresponding to the insertion slot 29 through the locking drive mechanism. Then, the mold changing trolley 2 is pushed toward the frame body 1 to the set position. At this time, the two locking pieces 30 at both ends of the mold changing trolley 2 extend into the two locking slots 28 on the frame body 1 respectively. Then, the locking drive mechanism is operated to drive the two locking pieces 30 to rotate a certain angle to the lateral position. At this time, the locking piece 30 cannot continue to move in the front-back direction in the locking slot 28, so as to realize the locking limit between the mold changing trolley 2 and the frame body 1.

[0040] For more details on the above structure, please refer to the appendix. Figure 5 The locking drive mechanism includes two drive shafts 31 extending along the front-rear direction of the mold changing trolley 2. The two drive shafts 31 are rotatably connected to the mold changing trolley 2. Two locking plates 30 are respectively connected to the rear ends of the two drive shafts 31. The front ends of the two drive shafts 31 are each connected to a rotating handle 32 for driving them to rotate around their own axis. The rear side of the mold changing trolley 2 is provided with positioning pressure rods 33 that are retractable in the front-rear direction on both sides of the two drive shafts 31. When the locking plate 30 is locked in the locking groove 28, the rear end of the positioning pressure rod 33 is pressed against and limited on the outer wall of the locking block 27, so that the front side of the locking plate 30 is pressed against and limited on the front side wall of the locking groove 28.

[0041] Preferably, two mounting base plates 36 are provided at both ends of the mold changing trolley 2, spaced apart front to back. Each mounting plate is provided with a bearing seat. The two ends of the two drive shafts 31 are rotatably connected to the bearing seats through bearings. Positioning baffles 37 are also provided on the mounting base plates 36 at the rear ends of the two mold changing trolleys 2. A guide slide plate 38 is slidably connected to the end of the drive shaft 31 that is close to the frame body 1. A spring 39 is provided between the guide slide plate 38 and the positioning baffle 37. Two positioning pressure rods 33 located on both sides of the drive shaft 31 are connected to the end of the guide slide plate 38 away from the positioning baffle 37. In the initial state, under the action of spring 39, the outer ends of the two positioning rods 33 extend beyond the locking plate 30. When the mold changing trolley 2 moves towards the side of the frame body 1, the positioning rods 33 at the corresponding positions at both ends will first abut against the front wall of the locking block 27. Then the mold changing trolley 2 continues to move towards the frame body 1 until the locking plate 30 passes through the insertion slot 29 in the longitudinal position. Then, the rotating handle 32 is operated to drive the drive shaft 31 to rotate until the locking plate 30 is in the lateral position, releasing the force acting on the pushing mold changing trolley 2. Under the action of elastic member 24, the front side of the locking plate 30 abuts against the front side wall of the locking groove 28 for limitation.

[0042] In this structure, there are two springs 39, and two guide posts are connected to the side of the guide slide plate 38 near the positioning baffle 37. The other end of the guide post is slidably fitted on the positioning baffle 37, and the two springs 39 are respectively fitted on the outside of the two guide posts to limit their compression movement.

[0043] See appendix for further details. Figure 5 Guide blocks 40 are provided at both ends of the front side of the frame body 1, and the two guide blocks 40 are located on the two sides of the two locking blocks 27 respectively. The two guide blocks 40 are provided with guide slopes on the side away from each other. Guide rollers 41 are provided at both ends of the rear side of the mold changing trolley 2. The two guide rollers 41 cooperate with the guide slopes of the two guide blocks 40 respectively. When the mold changing trolley 2 is connected to the frame body 1, it plays a guiding and positioning role, so that the locking piece 30 can pass through the insertion slot 29 more accurately and cooperate with the locking slot 28.

[0044] In this embodiment, the main support of the mold changing trolley 2 is assembled from multiple square tubes. Rollers are also provided at the bottom of the main support, and a push rod is provided at the front end to facilitate the movement of the trolley when changing molds.

[0045] In addition, in this embodiment, a control cabinet is also provided on the frame body 1, and multiple aviation plugs are provided on the upper mounting plate 3 to better expand the application range of the tooling.
