[0014] Beneficial effects

[0015] The utility model provides an accelerating ejecting structure for a high-drop headlight mold. Compared with the prior art, the following beneficial effects are achieved:

[0016] (1). The acceleration ejection structure for the high-drop headlight mold drives the piston rod, connecting plate, and moving box to slide synchronously to the left by starting the driving cylinder. The sliding of the moving box pushes the sliding tooth plate and ejector rod to slide synchronously to the left, and the headlight mold is ejected by the ejector rod. During this process, the sliding of the moving box also drives the acceleration tooth plate, limiting rod, and limiting spring to slide synchronously. When one end of the acceleration tooth plate contacts the top block, at this time, due to the continuous sliding of the moving box to the left, the acceleration tooth plate is limited by the top block and will drive the limiting rod to slide synchronously to the right, stretching the limiting spring, thereby causing the rotating gear and rotating rod to rotate counterclockwise synchronously. The rotation of the rotating gear will drive the ejector rod and sliding tooth plate to accelerate and slide to the left, so as to realize the acceleration ejection operation of the headlight mold and achieve rapid demolding. By setting up an acceleration ejection mechanism, under the drive of the driving cylinder, the ejector rod is used to eject and demold the formed headlight mold. At the same time, during the ejection and demolding process of the ejector rod, by setting up an acceleration component, the ejection operation of the ejector rod is accelerated to achieve rapid demolding.

[0017] (2). The acceleration ejection structure for the high-drop headlight mold drives the control screw rod to rotate by starting the control motor. The rotation of the control screw rod causes the adjusting plate, moving template, and positioning rod to slide synchronously to the right, so that the positioning rod slides into the positioning groove, and the surface of the moving template is attached to the surface of the fixed template. By setting up a control component, under the drive of the control motor, the position of the moving template can be adjusted flexibly, and by using the positioning rod and positioning groove, the moving template and the fixed template are attached more fully, thereby improving the injection molding quality of the subsequent headlight mold.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0024] Please refer to Figures 1-4 , the present invention provides a technical solution:

[0025] Regarding the accelerating ejection structure of the high-drop headlight mold,

[0026] It includes a top plate 1. The right side of the bottom of the top plate 1 is fixedly connected with a fixed template 2. The left side of the fixed template 2 is fixedly connected with a lower module 3. The inner wall of the fixed template 2 is fixedly connected with symmetric top blocks 4. The left side of the top plate 1 makes the moving template 6 slide through a control component 5. An accelerating ejection mechanism 7 is arranged inside the fixed template 2. The accelerating ejection mechanism 7 includes:

[0027] An ejection component 71, including a moving box 711. A sliding tooth plate 712 is slidably connected inside the moving box 711. One end of the sliding tooth plate 712 is fixedly connected with an ejector rod 713. One end of the sliding tooth plate 712 is fixedly connected with a return spring 714. One end of the return spring 714 is fixedly connected with the left side of the inner cavity of the fixed template 2;

[0028] A driving component 72, arranged on the right side of the inner wall of the fixed template 2;

[0029] An accelerating component 73, arranged inside the moving box 711.

[0030] An injection mold groove adapted to the lower module 3 is opened on the right side of the moving template 6; when the return spring 714 is not affected by external forces, the connecting block at one end of the top block 4 is in contact with one side of the moving box 711; there are two symmetric top blocks 4; the ejector rod 713 slides inside the lower module 3.

[0031] In this embodiment, the driving assembly 72 includes a driving cylinder 721 installed on the right side of the inner wall of the fixed template 2. One side of the driving cylinder 721 is fixedly connected to a connecting plate 722 through a piston rod, and the surface of the connecting plate 722 is fixedly connected to the surface of the moving box 711.

[0032] The driving cylinder 721 is communicated with an external air source through an air pipe.

[0033] In this embodiment, the acceleration assembly 73 includes a rotating rod 731 rotatably installed on the inner wall of the moving box 711 and an acceleration tooth plate 732 slidably installed inside the moving box 711. A rotating gear 733 is fixedly connected to the surface of the rotating rod 731. The surface of the rotating gear 733 meshes with one side of the acceleration tooth plate 732, and the surface of the rotating gear 733 meshes with one side of the sliding tooth plate 712. A limiting assembly 8 is provided at one end of the acceleration tooth plate 732.

[0034] In this embodiment, the limiting assembly 8 includes a limiting rod 81 installed at one end of the acceleration tooth plate 732. The surface of the limiting rod 81 is slidably connected to the inside of the moving box 711. One end of the limiting rod 81 is fixedly connected to a limiting spring 82, and one end of the limiting spring 82 is fixedly connected to one side of the moving box 711.

[0035] The limiting rod 81 is used to limit the sliding of the acceleration tooth plate 732 so that the acceleration tooth plate 732 does not shift when sliding left and right.

[0036] In this embodiment, a positioning groove 9 is formed on the left side of the fixed template 2, and a positioning rod 10 is fixedly connected to the right side of the moving template 6. The surface of the positioning rod 10 is slidably connected to the inner surface of the positioning groove 9.

[0037] The positioning groove 9 and the positioning rod 10 are used to maintain the stability during the fitting process of the fixed template 2 and the moving template 6, so that the two templates are fully fitted.

[0038] In this embodiment, the control assembly 5 includes a control motor 51 installed on the left side of the top plate 1 and a slide rail 52 installed on the top of the top plate 1.

The bottom of the adjusting plate 54 is fixedly connected to the top of the moving template 6, and the inside of the adjusting plate 54 is slidably connected to the surface of the slide rail 52.

[0039] The control motor 51 is a three-phase asynchronous motor and is connected to an external circuit through an electric wire; the surface of the control lead screw 53 is rotatably connected to the inside of the top plate 1, and the slide rail 52 is used to limit the sliding of the adjusting plate 54.

[0040] The accelerating ejection structure for the high-drop headlight mold drives the piston rod, connecting plate 722, and moving box 711 to slide synchronously to the left by starting the driving cylinder 721. The sliding of the moving box 711 pushes the sliding tooth plate 712 and the ejector rod 713 to slide synchronously to the left, and the headlight mold is ejected by the ejector rod 713. During this process, the sliding of the moving box 711 also drives the accelerating tooth plate 732, the limiting rod 81, and the limiting spring 82 to slide synchronously. When one end of the accelerating tooth plate 732 contacts the top block 4, at this time, due to the continuous sliding of the moving box 711 to the left, under the limitation of the top block 4, the accelerating tooth plate 732 drives the limiting rod 81 to slide synchronously to the right, and the limiting spring 82 is stretched, thereby causing the rotating gear 733 and the rotating rod 731 to rotate counterclockwise synchronously. The rotation of the rotating gear 733 drives the ejector rod 713 and the sliding tooth plate 712 to slide to the left at an accelerated speed, so as to realize the accelerating ejection operation of the headlight mold, realize rapid demolding. By setting the accelerating ejection mechanism 7, driven by the driving cylinder 721, the ejector rod 713 is driven to perform the ejection and demolding operation on the formed headlight mold. At the same time, during the ejection and demolding process of the ejector rod 713, by setting the accelerating component 73, the ejection operation of the ejector rod 713 is accelerated to realize rapid demolding.

[0041] The accelerating ejection structure for the high-drop headlight mold drives the control screw rod 53 to rotate by starting the control motor 51. The rotation of the control screw rod 53 causes the adjusting plate 54, the moving template 6, and the positioning rod 10 to slide synchronously to the right, so that the positioning rod 10 slides into the positioning groove 9, and the surface of the moving template 6 is attached to the surface of the fixed template 2. By setting the control component 5, driven by the control motor 51, the position of the moving template 6 can be adjusted flexibly, and by using the positioning rod 10 and the positioning groove 9, the moving template 6 and the fixed template 2 are attached more fully, thereby improving the injection quality of the subsequent headlight mold.

[0042] At the same time, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0043] During operation, first, start the control motor 51 to drive the control lead screw 53 to rotate. The rotation of the control lead screw 53 causes the adjusting plate 54, the moving template 6, and the positioning rod 10 to slide synchronously to the right, so that the positioning rod 10 slides into the interior of the positioning groove 9, and the surface of the moving template 6 is attached to the surface of the fixed template 2. Subsequently, the injection molding operation is carried out. After the injection molding of the headlight mold is completed, start the control motor 51 to drive the moving template 6 to reset. Then, start the driving cylinder 721 to drive the piston rod, the connecting plate 722, and the moving box 711 to slide synchronously to the left. The sliding of the moving box 711 pushes the sliding tooth plate 712 and the ejector rod 713 to slide synchronously to the left, and the headlight mold is ejected by the ejector rod 713. During this process, the sliding of the moving box 711 will also drive the acceleration tooth plate 732, the limiting rod 81, and the limiting spring 82 to slide synchronously. When one end of the acceleration tooth plate 732 contacts the top block 4, at this time, due to the continuous sliding of the moving box 711 to the left, under the limitation of the top block 4, the acceleration tooth plate 732 will drive the limiting rod 81 to slide synchronously to the right, and the limiting spring 82 is stretched. As a result, the rotating gear 733 and the rotating rod 731 rotate counterclockwise synchronously. The rotation of the rotating gear 733 will drive the ejector rod 713 and the sliding tooth plate 712 to slide to the left at an accelerated speed, so as to realize the accelerated ejection operation of the headlight mold and achieve rapid demolding.
