[0002] The automobile window regulator bracket assembly is an important component in the automobile window system. It plays a role in supporting and fixing the window glass. The quality and performance of the window regulator bracket assembly are directly related to the stability and safety of the automobile window system. Injection molding technology is an efficient and precise manufacturing method, which is widely used in the manufacturing of automobile parts. Generally, an injection molding device is used to manufacture the automobile window regulator bracket assembly. Injection molding technology has the advantages of high production efficiency, low cost, and easy realization of automated production. However, due to the usually complex shape and structure of the automobile window regulator bracket assembly, during the injection molding process, most are processed by fixed molds for injection molding production. However, in actual operation, the fixed molds are not convenient for maintenance and repair, resulting in inconvenience in the injection molding production of automobile parts and affecting the production and processing efficiency of injection molded parts. Moreover, the existing equipment simply positions and combines the molds during injection molding. During long-term use, the molds are prone to displacement, increasing the number of defective injection molded parts produced. It is difficult to perform effective and rapid demolding after injection molding, further affecting the production efficiency.

[0070] A fixed frame device 2 is fixed on the workbench 1 and is located on the right side of the slide rail 11.

[0071] A control device 3 is on the same straight line as the fixed frame device 2 and is slidably arranged on the slide rail 11.

[0072] A pushing mechanism 4 is fixed at the center of the control device 3.

[0074] A fixed template 6 is fixed at the center of the fixed frame device 2 and is located on the side of the fixed frame device 2 close to the moving frame device 5.

[0075] A moving template 7 is fixed at the center of the moving frame device 5 and corresponds to the fixed template 6.

[0076] An injection molding device 8 is fixed at one end of the workbench 1 far from the slide rail 11, and the injection molding device 8 is fixedly connected to the fixed frame device 2.

[0079] The injection connection port 22 is arranged at the center of the fixed plate 21, and the injection connection port 22 is fixedly connected with the injection device 8;

[0080] There are four limiting shafts 23 distributed annularly, which are fixed at the four corners of the fixed plate 21, and one end of the limiting shaft 23 away from the fixed plate 21 is a threaded structure;

[0081] A plurality of moving clamping components 24 are distributed annularly and are fixed on the side of the fixed plate 21 away from the injection device 8 to fix the fixed template 6;

[0082] A plurality of first positioning blocks 25 are distributed annularly and are fixed on the side surface of the fixed plate 21 adjacent to the moving clamping component 24.

[0083] That is to say, under the action of the moving clamping component 24, the fixed template 6 is fixed, and the injection port of the fixed template 6 is connected with the injection device 8 through the injection connection port 22 on the fixed plate 21.

[0084] In this embodiment, the control device 3 includes:

[0085] The control board 31 is slidably connected with the limiting shaft 23 and the bottom is slidably connected with the slide rail 11;

[0086] A plurality of moving shaft sleeves 32 are distributed annularly and are arranged corresponding to the limiting shafts 23. They are rotatably arranged on the side of the control board 31 away from the fixed plate 21 and are threadedly connected with the limiting shafts 23;

[0087] The rotating gear 33 is arranged corresponding to the moving shaft sleeve 32. It is slidably arranged on the limiting shaft 23, is fixedly connected with the moving shaft sleeve 32, and the rotating gear 33 is rotatably connected with the limiting shaft 23;

[0088] The transmission gear ring 34 is rotatably arranged on the side of the control board 31 and meshes with the rotating gear 33;

[0089] The driving motor 35 is fixed on the side of the control board 31, and the shaft body of the driving motor 35 is meshed with the transmission gear ring 34 through a gear.

[0090] That is to say, driven by the driving motor 35, the transmission gear ring 34 drives the rotating gear 33 to rotate forward, and then drives the moving shaft sleeve 32 to rotate on the limiting shaft 23. Under the restriction of the fixed plate 21, the limiting shaft 23 is in a fixed state, that is, the moving shaft sleeve 32 moves on the limiting shaft 23 through the thread, drives the control plate 31 to move in the direction of the fixed frame device 2, and at the same time drives the moving frame device 5 to move in the direction of the fixed frame device 2, drives the moving template 7 to move towards the fixed template 6, and fixes the moving template 7 and the fixed template 6 together for injection molding work; conversely, driven by the driving motor 35, the transmission gear ring 34 drives the rotating gear 33 to rotate reversely, and then the moving shaft sleeve 32 moves on the limiting shaft 23 through the thread, drives the control plate 31 to move away from the fixed frame device 2, and at the same time drives the moving frame device 5 to move away from the fixed frame device 2, drives the moving template 7 to separate from the fixed template 6, and ejects the injection-molded automotive window lifter bracket assembly, which falls onto the workbench 1 and is conveyed through the output port 12.

[0091] In this embodiment, the pushing mechanism 4 includes:

[0092] A hydraulic press 41, fixed to the side of the control device 3, and the hydraulic press 41 is provided with a push rod that passes through the control plate 31;

[0093] A pushing panel 42, arranged between the control device 3 and the moving frame device 5, is slidably connected to the limiting shaft 23, and the center of the pushing panel 42 is fixedly connected to the push rod of the hydraulic press 41. A plurality of annularly distributed locking mechanisms are provided on the side of the pushing panel 42 away from the hydraulic press 41.

[0094] That is to say, when the control device 3 is in a stationary state, at this time, by controlling the push rod of the hydraulic press 41 to extend, the pushing panel 42 is driven to move in the direction of the moving frame device 5, and the moving frame device 5 is controlled by the pushing panel 42 to clamp and fix the moving template 7; conversely, by controlling the push rod of the hydraulic press 41 to retract, the pushing panel 42 is driven to move away from the moving frame device 5, and the moving frame device 5 is controlled by the pushing panel 42 to put down the moving template 7. Under the control of the pushing mechanism 4, the moving template 7 can be quickly clamped and fixed, and the mold can also be quickly removed for maintenance, problems can be discovered and processed in time, and the defective rate of injection molded parts can be effectively reduced.

[0095] In this embodiment, the moving frame device 5 includes:

[0096] A moving plate 51, in a loop shape, is slidably arranged on the limiting shaft 23, and the moving plate 51 is fixedly connected to the control device 3;

[0097] A plurality of clamping and fixing components 52 are annularly distributed and fixed inside the moving plate 51;

[0098] The transmission shaft assembly 53 is correspondingly arranged with the clamping and fixing assembly 52. One end of the transmission shaft assembly 53 is fixedly connected to the clamping and fixing assembly 52, and the other end is connected to the locking mechanism on the pushing panel 42. Moreover, the transmission shaft assembly 53 is slidably connected to the pushing panel 42;

[0099] The positioning and ejecting assembly 54 is fixed on the outer side of the moving plate 51 and corresponds to the first positioning block 25.

[0100] That is to say, when clamping and fixing the moving template 7, by controlling the push rod of the hydraulic press 41 to extend, the pushing panel 42 is driven to move towards the direction of the moving frame device 5. At this time, the locking mechanism on the pushing panel 42 fixes the transmission shaft assembly 53, and the pushing panel 42 controls the movement of the transmission shaft assembly 53 within the moving frame device 5 to drive the clamping and fixing assembly 52 to clamp and fix the moving template 7. And when the clamping and fixing assembly 52 moves towards the moving template 7, if there is a situation where the distances between the clamping and fixing assemblies 52 and the moving template 7 are different, at this time when the clamping and fixing assembly 52 is in contact with the moving template 7, the locking mechanism on the pushing panel 42 releases the corresponding transmission shaft assembly 53, enabling the transmission shaft assembly 53 to slide within the pushing panel 42, and then fixing the remaining sides of the moving template 7. It should be noted that the transmission shaft assembly 53 can only slide relative to the pushing panel 42 and cannot rotate on the pushing panel 42; conversely, by controlling the push rod of the hydraulic press 41 to retract, the pushing panel 42 is driven to move away from the moving frame device 5. At this time, the clamping and fixing assembly 52 resets in sequence. After the transmission shaft assembly 53 resets, it is fixed again by the locking mechanism on the pushing panel 42 until the clamping and fixing assembly 52 puts down the moving template 7.

[0101] In this embodiment, the clamping and fixing assembly 52 includes:

[0102] The limiting member 521 is fixed within the moving plate 51;

[0103] The transmission gear 522 is rotatably arranged within the limiting member 521, and the transmission gear 522 is fixedly connected to the transmission shaft assembly 53;

[0104] The rack 523 is movably arranged within the limiting member 521, and the rack 523 meshes with the transmission gear 522;

[0105] The pushing shaft 524 is fixed at one end of the rack 523 close to the center of the moving plate 51, and the pushing shaft 524 passes through the inner wall of the moving plate 51;

[0106] The fixing member 525 is arranged in the middle of the moving plate 51 and is fixedly connected to the pushing shaft 524.

[0107] That is to say, when the push rod of the hydraulic press 41 extends to drive the push panel 42 to move in the direction of the moving frame device 5, at this time, the transmission gear 522 is driven to rotate forward by the transmission shaft assembly 53, and then the push shaft 524 is driven to move towards the center of the moving plate 51 through the rack 523, driving the fixing member 525 to fix the moving template 7; conversely, when the push rod of the hydraulic press 41 retracts to drive the push panel 42 to move away from the moving frame device 5, at this time, the transmission gear 522 is driven to rotate reversely by the transmission shaft assembly 53, and then the push shaft 524 is driven to move away from the center of the moving plate 51 through the rack 523, driving the fixing member 525 to lower the moving template 7.

[0108] In this embodiment, the transmission shaft assembly 53 includes:

[0109] A rotating outer shaft 531, rotatably arranged in the moving plate 51, with one end fixedly connected to the transmission gear 522;

[0110] A transmission shaft sleeve 532, fixed to the end of the rotating outer shaft 531 away from the transmission gear 522;

[0111] A driving inner shaft 533, with one end arranged inside the rotating outer shaft 531 and threadedly connected to the transmission shaft sleeve 532, and the other end connected to the locking mechanism on the push panel 42.

[0112] That is to say, when the push rod of the hydraulic press 41 extends to drive the push panel 42 to move in the direction of the moving frame device 5, the locking mechanism on the push panel 42 fixes the driving inner shaft 533 at this time, and then pushes the driving inner shaft 533 to move within the rotating outer shaft 531. Under the action of the transmission shaft sleeve 532, the rotating outer shaft 531 is driven to rotate forward, that is, the transmission gear 522 is driven to rotate forward through the rotating outer shaft 531. Then, the push shaft 524 is driven to move towards the center of the moving plate 51 through the rack 523, and the fixing member 525 drives to fix the moving template 7; conversely, when the push rod of the hydraulic press 41 retracts to drive the push panel 42 to move in the direction away from the moving frame device 5, the locking mechanism on the push panel 42 fixes the driving inner shaft 533 at this time, and then pushes the driving inner shaft 533 to move within the rotating outer shaft 531. Under the action of the transmission shaft sleeve 532, the rotating outer shaft 531 is driven to rotate reversely, that is, the transmission gear 522 is driven to rotate reversely through the rotating outer shaft 531. Then, the push shaft 524 is driven to move away from the center of the moving plate 51 through the rack 523, and the fixing member 525 drives to lower the moving template 7. It should be noted that if there is a situation where the distances between the clamping and fixing components 52 and the moving template 7 are different, when the clamping and fixing component 52 is in contact with the moving template 7, the locking mechanism on the push panel 42 releases the corresponding driving inner shaft 533, so that the driving inner shaft 533 slides within the push panel 42. When removing the moving template 7, the driving inner shaft 533 needs to be reset first, and then locked and fixed by the locking mechanism on the push panel 42.

[0113] In this embodiment, the positioning and ejecting assembly 54 includes:

[0114] A plurality of second positioning blocks 541 are annularly distributed and fixed on the side of the moving plate 51, corresponding to the first positioning blocks 25;

[0115] A positioning shaft 542 passes through the center of the second positioning block 541 and is slidably connected to the second positioning block 541. A gasket 5421 is provided on the positioning shaft 542, and the gasket 5421 is located inside the second positioning block 541 and fits against the inner wall close to the first positioning block 25;

[0116] A return spring 543 is sleeved on the positioning shaft 542 and is located inside the second positioning block 541;

[0117] A connecting member 544 is fixed to the end of the positioning shaft 542 away from the first positioning block 25;

[0118] An ejecting mechanism 545 is arranged in parallel on the left side of the moving plate 51, and the sides of the ejecting mechanism 545 are respectively fixedly connected to the plurality of connecting members 544.

[0119] That is to say, after the moving template 7 is fixed, under the action of the control device 3, the moving frame device 5 is driven to move towards the position where the fixed frame device 2 is located, driving the moving template 7 to move towards the fixed template 6, so that the moving template 7 and the fixed template 6 are fixed together. At the same time, the second positioning block 541 fits with the first positioning block 25, and the first positioning block 25 pushes out the positioning shaft 542. At the same time, under the action of the gasket 5421, the return spring 543 is compressed, and the ejecting mechanism 545 is driven through the connecting member 544 to disengage from the moving template 7. After the injection molding is completed, under the action of the control device 3, the moving frame device 5 is driven to move away from the position of the fixed frame device 2, driving the moving template 7 to disengage from the fixed template 6. At this time, the second positioning block 541 disengages from the first positioning block 25, the return spring 543 rebounds and resets, driving the positioning shaft 542 to reset. At the same time, the ejecting mechanism 545 is driven through the connecting member 544 to move towards the moving template 7, ejecting the injection molded part, so that the injection molded part quickly disengages from the moving template 7, facilitating the next injection molding work.

[0120] In this embodiment, the ejecting mechanism 545 includes:

[0121] A connecting panel 5451, fixed between a plurality of connecting members 544;

[0122] A ejector pin 5452, movably arranged on one side of the connecting panel 5451 close to the moving plate 51, corresponding to the ejector pin hole on the moving template 7.

[0123] That is to say, after the moving template 7 is fixed, under the action of the control device 3, the moving frame device 5 is driven to move towards the position where the fixed frame device 2 is located, driving the moving template 7 to move towards the fixed template 6, so that the moving template 7 and the fixed template 6 are fixed together. At the same time, the second positioning block 541 fits with the first positioning block 25, and the first positioning block 25 pushes out the positioning shaft 542. At the same time, under the action of the gasket 5421, the return spring 543 is compressed, and the connecting panel 5451 is driven through the connecting member 544 to move away from the moving template 7, so that the ejector pin 5452 retracts into the ejector pin hole of the moving template 7. After the injection molding is completed, under the action of the control device 3, the moving frame device 5 is driven to move away from the position of the fixed frame device 2, driving the moving template 7 to disengage from the fixed template 6. At this time, the second positioning block 541 disengages from the first positioning block 25, the return spring 543 rebounds and resets, driving the positioning shaft 542 to reset. At the same time, the connecting panel 5451 is driven through the connecting member 544 to move towards the moving template 7, so that the ejector pin 5452 extends out of the ejector pin hole of the moving template 7, ejecting the injection molded part, so that the injection molded part quickly disengages from the moving template 7, facilitating the next injection molding work.

[0124] In this embodiment, an application of an auxiliary device for an injection molding device for manufacturing an automotive window regulator bracket assembly includes the following steps:

[0125] Step 1: First, fix the stationary template 6 on the fixed plate 21 by moving the clamping assembly 24. Then, place the moving template 7 in the middle of the moving plate 51. At this time, control the push rod of the hydraulic press 41 to extend, drive the pushing panel 42 to move in the direction of the moving frame device 5, and fix the driving inner shaft 533 through the locking mechanism on the pushing panel 42. Then, push the driving inner shaft 533 to move within the rotating outer shaft 531. Under the action of the transmission shaft sleeve 532, drive the rotating outer shaft 531 to rotate forward, drive the transmission gear 522 to rotate forward through the rotating outer shaft 531, and then drive the pushing shaft 524 to move towards the center of the moving plate 51 through the rack 523, drive the fixing member 525 to fix the moving template 7, and the stationary template 6 and the moving template 7 are in a relative position. When the mold needs to be repaired, control the push rod of the hydraulic press 41 to retract, drive the pushing panel 42 to move away from the moving frame device 5. At this time, drive the transmission gear 522 to rotate reversely through the transmission shaft assembly 53, and then drive the pushing shaft 524 to move away from the center of the moving plate 51 through the rack 523, drive the fixing member 525 to lower the moving template 7, and the stationary template 6 can be lowered through the moving clamping assembly 24 for repair;

[0126] Step 2: Then, move the ejector pin 5452 to a position corresponding to the ejector pin hole on the moving template 7. Under the action of the return spring 543 inside the second positioning block 541, the positioning shaft 542 drives the connection panel 5451 to move through the connecting member 544. Under the action of the connection panel 5451, the ejector pin 5452 passes through the moving template 7;

[0127] Step 3: Then, drive the moving frame device 5 to move towards the position where the fixed frame device 2 is located through the control device 3, so that the stationary template 6 and the moving template 7 are in contact. At the same time, the second positioning block 541 is in contact with the first positioning block 25. The first positioning block 25 pushes out the positioning shaft 542. At the same time, under the action of the gasket 5421, compress the return spring 543, and drive the connection panel 5451 to move away from the moving template 7 through the connecting member 544, so that the ejector pin 5452 retracts into the ejector pin hole of the moving template 7;

[0128] Step 4: Then, perform injection molding through the injection molding device 8. After the injection molding is completed, under the action of the control device 3, drive the moving frame device 5 to move away from the fixed frame device 2, drive the moving template 7 to separate from the stationary template 6. At this time, the second positioning block 541 separates from the first positioning block 25, the return spring 543 bounces back to reset, drives the positioning shaft 542 to reset, and at the same time drives the connection panel 5451 to move towards the moving template 7 through the connecting member 544, so that the ejector pin 5452 extends out of the ejector pin hole of the moving template 7, eject the injection molded part, make the injection molded part quickly separate from the moving template 7, and the injection molded part falls and is output through the output port 12, so as to facilitate the next injection molding work.
