[0002] The automobile window bracket assembly is an important component in the automobile window system. It plays the role of supporting and fixing the window glass. The quality and performance of the window 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 manufacture of automobile parts. Generally, injection molding equipment is used to manufacture the automobile window bracket assembly. Injection molding technology has the advantages of high production efficiency, low cost, and easy to realize automated production. However, due to the shape and structure of the automobile window bracket assembly, most of them are processed by injection molding through fixed molds during the injection molding process. However, in actual operation, the fixed mold is not convenient for maintenance, which causes inconvenience in the injection molding production of automobile parts and affects the production and processing efficiency of injection molded parts. In addition, the existing equipment performs simple positioning and combination of the mold during injection molding. During long-term use, the mold is prone to displacement, which increases the number of defective injection molded parts produced.

Under the restriction of the fixed plate 21, the limiting shaft 23 is in a fixed state, that is, the moving 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 drives the moving frame device 5 to move in the direction of the fixed frame device 2, drives the movable template 7 to move toward the fixed template 6, so that the movable template 7 and the fixed template 6 are fixed together for injection molding; on the contrary, driven by the driving motor 35, the transmission gear ring 34 drives the rotating gear 33 to rotate reversely, and then the moving sleeve 32 moves on the limiting shaft 23 through the thread, drives the control plate 31 to move in the direction away from the fixed frame device 2, and drives the moving frame device 5 to move in the direction away from the fixed frame device 2, drives the movable template 7 to separate from the fixed template 6, and ejects the injection-molded automobile window-lifting bracket assembly, falls onto the workbench 1, and is transported through the output port 12.

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

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

[0093] The pushing panel 42 is arranged between the control device 3 and the movable frame device 5, and is slidably connected to the limit shaft 23. 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, the push rod of the hydraulic press 41 is extended to drive the pushing panel 42 to move in the direction of the movable frame device 5, and the movable frame device 5 is controlled by the pushing panel 42 to clamp and fix the movable template 7; conversely, the push rod of the hydraulic press 41 is retracted to drive the pushing panel 42 to move away from the movable frame device 5, and the movable frame device 5 is controlled by the pushing panel 42 to lower the movable template 7. Under the control of the pushing mechanism 4, the movable template 7 can be quickly clamped and fixed, and the mold can also be quickly removed for inspection, so that problems can be discovered and dealt with in time, and the defective rate of injection molded parts can be effectively reduced.

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

[0096] The movable plate 51 is in a circular shape and is slidably disposed on the limit shaft 23, and the movable plate 51 is fixedly connected to the control device 3;

[0097] A plurality of clamping and fixing components 52 are provided in an annular distribution and fixed inside the moving plate 51;

[0098] The transmission shaft assembly 53 is arranged corresponding to 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. 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 movable plate 51 and corresponds to the first positioning block 25 .

[0100] That is to say, when the movable platen 7 is clamped and fixed, the push rod of the hydraulic press 41 is extended to drive the push panel 42 to move in the direction of the movable frame device 5. At this time, the locking mechanism on the push panel 42 fixes the transmission shaft assembly 53, and the push panel 42 controls the transmission shaft assembly 53 to move in the movable frame device 5 to drive the clamping and fixing assembly 52 to clamp and fix the movable platen 7. When the clamping and fixing assembly 52 moves toward the movable platen 7, if there is a situation where the spacing between the clamping and fixing assemblies 52 and the movable platen 7 is different, when the clamping and fixing assemblies 52 are in contact with the movable platen 7, the push panel 42 is locked. The locking mechanism on 42 releases the corresponding transmission shaft assembly 53, allowing the transmission shaft assembly 53 to slide in the pushing panel 42, and then the remaining sides of the movable template 7 are fixed. It should be noted that the transmission shaft assembly 53 can only slide with the pushing panel 42 and cannot rotate on the pushing panel 42; on the contrary, by controlling the push rod of the hydraulic press 41 to be retracted, the pushing panel 42 is driven to move away from the moving frame device 5. At this time, the clamping and fixing assemblies 52 are reset in turn, and the transmission shaft assembly 53 is fixed again by the locking mechanism on the pushing panel 42 after being reset until the clamping and fixing assembly 52 puts down the movable template 7.

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

[0102] The limiting member 521 is fixed in the movable plate 51;

[0103] A transmission gear 522 is rotatably disposed in the limiting member 521, and the transmission gear 522 is fixedly connected to the transmission shaft assembly 53;

[0104] The rack 523 is movably disposed in the limiting member 521, and the rack 523 is meshed with the transmission gear 522;

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

[0106] The fixing member 525 is disposed 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 control hydraulic press 41 is extended, driving the push panel 42 to move in the direction of the moving frame device 5, the transmission gear 522 is driven to rotate forward through the transmission shaft assembly 53, and then the push shaft 524 is driven to move toward the center of the moving plate 51 through the rack 523, driving the fixing part 525 to fix the moving template 7; conversely, when the push rod of the control hydraulic press 41 is retracted, driving the push panel 42 to move away from the moving frame device 5, the transmission gear 522 is driven to rotate reversely through 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 part 525 to lower the moving template 7.

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

[0109] The rotating outer shaft 531 is rotatably disposed in the moving plate 51, and one end of the rotating outer shaft 531 is fixedly connected to the transmission gear 522;

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

[0111] The driving inner shaft 533 has one end disposed inside the rotating outer shaft 531 and threadedly connected to the transmission sleeve 532 , and the other end connected to the locking mechanism on the pushing panel 42 .

[0112] That is to say, when the push rod of the control hydraulic press 41 is extended, driving the push panel 42 to move in the direction where the moving frame device 5 is located, the locking mechanism on the push panel 42 fixes the driving inner shaft 533, and then pushes the driving inner shaft 533 to move in the rotating outer shaft 531, and under the action of the transmission shaft sleeve 532, drives the rotating outer shaft 531 to rotate forward, that is, the rotating outer shaft 531 drives the transmission gear 522 to rotate forward, and then drives the push shaft 524 to move toward the center of the moving plate 51 through the rack 523, and drives the fixing part 525 to fix the moving template 7; conversely, when the push rod of the control hydraulic press 41 is retracted, driving 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, and then pushes the driving inner shaft 533 to move in the rotating outer shaft 531. The dynamic driving inner shaft 533 moves in the rotating outer shaft 531, and under the action of the transmission shaft sleeve 532, the rotating outer shaft 531 is driven to reverse, that is, the transmission gear 522 is driven to reverse by the rotating outer shaft 531, and then the pushing shaft 524 is driven to move away from the center of the movable plate 51 through the rack 523, and the fixing part 525 is driven to lower the movable template 7. It should be noted that if the spacing between each clamping and fixing component 52 and the movable template 7 is different, when the clamping and fixing component 52 is in contact with the movable template 7, the locking mechanism on the pushing panel 42 releases the corresponding driving inner shaft 533, so that the driving inner shaft 533 slides in the pushing panel 42. When the movable template 7 is removed, the driving inner shaft 533 must be reset first, and then locked and fixed by the locking mechanism on the pushing panel 42.

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

A gasket 5421 is provided on the positioning shaft 542. 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] The return spring 543 is sleeved on the positioning shaft 542 and is located in the second positioning block 541;

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

[0118] The ejection mechanism 545 is arranged in parallel on the left side of the movable plate 51 , and the side portions of the ejection mechanism 545 are fixedly connected to the plurality of connecting members 544 .

[0119] That is to say, after the movable template 7 is fixed, under the action of the control device 3, the movable frame device 5 is driven to move to the position of the fixed frame device 2, and the movable template 7 is driven to move toward the fixed template 6, so that the movable template 7 and the fixed template 6 are fixed together, and at the same time, the second positioning block 541 is in contact with the first positioning block 25, and the first positioning block 25 ejects the positioning shaft 542. At the same time, under the action of the gasket 5421, the reset spring 543 is compressed, and the ejection mechanism 545 is driven to separate from the movable template 7 through the connecting member 544. After the injection molding is completed, under the action of the control device 3, the movable frame device 5 is driven to move to a position away from the fixed frame device 2, and the movable template 7 is driven to separate from the fixed template 6. At this time, the second positioning block 541 is separated from the first positioning block 25, and the reset spring 543 pops up and resets, driving the positioning shaft 542 to reset, and at the same time, the ejection mechanism 545 is driven to move toward the movable template 7 through the connecting member 544, and the injection molded part is ejected, so that the injection molded part is quickly separated from the movable template 7, so as to facilitate the injection molding work again.

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

[0121] A connecting panel 5451 is fixed between the plurality of connecting members 544;

[0122] The ejector pin 5452 is movably arranged on a side of the connecting panel 5451 close to the movable plate 51 , corresponding to the ejector pin hole on the movable plate 7 .

[0123] That is to say, after the movable platen 7 is fixed, under the action of the control device 3, the movable frame device 5 is driven to move toward the position of the fixed frame device 2, and the movable platen 7 is driven to move toward the fixed platen 6, so that the movable platen 7 and the fixed platen 6 are fixed together, and at the same time, the second positioning block 541 is fitted with the first positioning block 25, and the first positioning block 25 pushes the positioning shaft 542 out, and at the same time, under the action of the gasket 5421, the reset spring 543 is compressed, and the connecting panel 5451 is driven to move away from the movable platen 7 through the connecting member 544, so that the ejector pin 5452 shrinks to the top of the movable platen 7 In the pinhole, after the injection molding is completed, under the action of the control device 3, the movable frame device 5 is driven to move to a position away from the fixed frame device 2, and the movable template 7 is driven to separate from the fixed template 6. At this time, the second positioning block 541 is separated from the first positioning block 25, and the reset spring 543 bounces up and resets, driving the positioning shaft 542 to reset. At the same time, the connecting panel 5451 is driven to move in the direction close to the movable template 7 through the connecting member 544, so that the ejector pin 5452 automatically extends from the ejector pin hole of the template 7, ejects the completed injection molded part, and quickly separates the injection molded part from the movable template 7, so as to facilitate injection molding again.

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

[0125] Step 1, first fix the fixed template 6 on the fixed plate 21 by moving the clamping assembly 24, then place the movable template 7 in the middle of the movable plate 51, at this time control the push rod of the hydraulic press 41 to extend, drive the push panel 42 to move in the direction of the movable frame device 5, and fix the driving inner shaft 533 through the locking mechanism on the push panel 42, and then push the driving inner shaft 533 to move in the rotating outer shaft 531, under the action of the transmission shaft sleeve 532, drive the rotating outer shaft 531 to rotate forward, and drive the transmission gear 522 to rotate forward through the rotating outer shaft 531, and then drive the push rod 523 to move forward through the rack 523. The delivery shaft 524 moves toward the center of the movable plate 51, driving the fixing member 525 to fix the movable plate 7, and the fixed plate 6 and the movable plate 7 are in relative positions. When the mold needs to be repaired, the push rod of the hydraulic press 41 can be controlled to be retracted, driving the push panel 42 to move away from the movable frame device 5, and at this time, the transmission gear 522 is driven to reverse through the transmission shaft assembly 53, and then the push shaft 524 is driven to move away from the center of the movable plate 51 through the rack 523, driving the fixing member 525 to put down the movable plate 7, and the fixed plate 6 can be put down through the mobile clamping assembly 24 for maintenance;

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

[0127] Step 3, the control device 3 then drives the movable frame device 5 to move to the position where the fixed frame device 2 is located, so that the fixed template 6 and the movable template 7 are fitted together, and at the same time, the second positioning block 541 is fitted with the first positioning block 25, and the first positioning block 25 pushes out the positioning shaft 542, and at the same time, under the action of the gasket 5421, the reset spring 543 is compressed, and the connecting panel 5451 is driven to move away from the movable template 7 through the connecting member 544, so that the ejector pin 5452 is retracted into the ejector pin hole of the movable template 7;

[0128] Step 4, then injection molding is performed through the injection molding device 8. After the injection molding is completed, under the action of the control device 3, the movable frame device 5 is driven to move to a position away from the fixed frame device 2, and the movable template 7 is driven to separate from the fixed template 6. At this time, the second positioning block 541 is separated from the first positioning block 25, and the reset spring 543 bounces up and resets, driving the positioning shaft 542 to reset. At the same time, the connecting panel 5451 is driven by the connecting member 544 to move toward the direction close to the movable template 7, so that the ejector pin 5452 automatically extends from the ejector pin hole of the template 7, ejects the completed injection molded part, and quickly separates from the movable template 7. The injection molded part falls and is output through the output port 12, so that the injection molding work can be performed again.
