Description

Technical Field

[0001] This application relates to the field of mold manufacturing, and in particular to an injection mold for automotive grilles. Background Technology

[0002] Automotive grille injection molds are mainly used to efficiently, accurately, and in large quantities produce plastic grille parts that meet design requirements. They are an indispensable processing tool in automobile factory production.

[0003] The current automotive grille injection mold first combines the stationary mold and the moving mold, then injects the molten raw material into the cavity formed by the mold through the injection pipe, and then cools and solidifies. After cooling and solidification, the moving mold opens and the part is ejected from the mold by ejector pins, thus completing the injection molding process.

[0004] When the part is ejected by the ejector pin, the side wall of the part will rub against the inner wall of the mold, resulting in white marks. Due to the horizontal pressure during the demolding process, the white marks mostly appear on the side walls of the horizontal sides of the part, causing the side walls of the part to rub against the inner wall of the mold during demolding, resulting in damage and defects. Utility Model Content

[0005] In order to improve the problem of damage and defects on the sidewalls of parts during demolding, this application provides an injection mold for automotive grilles.

[0006] The technical solution for an automotive grille injection mold provided in this application is as follows: An injection mold for an automotive grille includes a support platform, wherein the support platform is provided with a horizontal opening and closing mechanism for opening the horizontal sides of the mold, and a lifting mechanism for ejecting the mold is provided inside the support platform, and a moving mold base is provided on the top of the horizontal opening and closing mechanism. The horizontal opening and closing mechanism includes a movable frame disposed on the top of the support platform.

[0007] By adopting the above technical solution, during demolding, the operator moves the moving mold base, thereby exposing the top of the part. Then, the horizontal opening and closing mechanism causes the movable frames of the side walls of the part to open horizontally to both sides. The lifting mechanism then pushes the part out. During the ejection process, because the movable frames on both sides move horizontally, the horizontal sides of the part do not contact the inner wall of the mold during the ejection process. This prevents the side walls of the part from rubbing against the inner wall of the mold when the part is taken out of the mold, thus avoiding damage and white marks caused by friction.

[0008] Preferably, the horizontal opening and closing mechanism includes a stationary mold base, which is fixedly connected to the top of the support platform. A cylinder is fixedly connected to the bottom of the stationary mold base, and a horizontal plate is fixedly passed through the output shaft end of the cylinder. Both horizontal ends of the horizontal plate are fixedly connected to linkage components.

[0009] By adopting the above technical solution, the cylinder is fixed by the static mold base, and the cylinder drives the horizontal plate to move vertically, thereby driving the linkage components to start simultaneously through a single drive source.

[0010] Preferably, the linkage component includes a first support, the fixed end of the first support is fixedly connected to both horizontal ends of the horizontal plate, the movable end of the first support is rotatably connected to a connecting rod, the end of the connecting rod away from the first support is rotatably connected to a second support, and the fixed end of the second support is fixedly connected to a sliding component.

[0011] By adopting the above technical solution, the horizontal plate will drive the vertical movement of support one, and through the connecting rod, the vertical movement of support one will be transformed into the horizontal movement of support two, thereby making the structural movement smoother. Support two will drive the sliding component to move.

[0012] Preferably, the sliding assembly includes a sliding plate fixedly connected to the fixed end of the second support, a fixed block fixedly connected to the bottom of the sliding plate, a horizontal column movably passing through the side wall of the fixed block, a vertical plate fixedly connected to the end of the fixed block, and a synchronization assembly fixedly connected to the top of the sliding plate.

[0013] By adopting the above technical solution, the horizontal movement of the sliding plate will drive the fixed block to move horizontally in sync. The fixed block will be limited by the horizontal column to move horizontally. The horizontal column limits the sliding plate, so that the sliding plate is always in a horizontal movement state. The sliding plate will drive the synchronous component to move.

[0014] Preferably, the sliding plate is slidably connected to the stationary mold base, the end of the horizontal column away from the vertical plate is fixedly connected to the inner wall of the stationary mold base, and the bottom of the vertical plate is fixedly connected to the bottom of the inner wall of the stationary mold base.

[0015] By adopting the above technical solution, the static mold base limits the horizontal movement of the sliding plate, and fixes the horizontal column and vertical plate by the static mold base, thereby making the directional limitation of the fixed block more stable.

[0016] Preferably, the synchronization component includes a sliding block, the bottom of which is fixedly connected to the top of the sliding plate, the sliding block is slidably connected to the stationary mold base, the side wall of the sliding block is fixedly connected to the movable frame, and the top of the stationary mold base is fixedly connected to a fixed frame that engages with the movable frame.

[0017] By adopting the above technical solution, the horizontal movement of the sliding plate will drive the sliding block to move horizontally in sync. The fixed frame and the movable frame are engaged at both ends by protrusions, thereby avoiding gaps that affect the molding process and making the mold surface smoother.

[0018] Preferably, the lifting mechanism includes a limiting plate fixedly passing through the cylinder output shaft, a synchronizing plate movably passing through the outer wall of the cylinder output shaft, vertical bars fixedly connected to both horizontal ends of the synchronizing plate, vertical members fixedly connected to both horizontal ends of the vertical bars, and a sliding frame fixedly connected to the top of the vertical members.

[0019] By adopting the above technical solution, the vertical movement of the limiting plate drives the vertical movement of the synchronization plate, which in turn drives the vertical movement of the vertical bar, which in turn drives the vertical movement of the vertical component. The vertical component is symmetrically arranged at the four corners of the inner wall of the stationary mold base, thereby making the vertical movement of the sliding frame more stable.

[0020] Preferably, the vertical member is slidably connected to the stationary mold base, and the sliding frame is slidably connected to the stationary mold base.

[0021] By adopting the above technical solution, the vertical component and the sliding frame are vertically limited by the static mold base, so that the vertical component and the sliding frame can rise steadily vertically. The sliding frame is limited by the static mold base, so that the sliding frame can only move vertically.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The horizontal opening and closing mechanism drives the movable frame to move horizontally to both sides, and then the lifting mechanism pushes the part out. This ensures that the movable frame, which has a wrapping effect on the part, does not come into contact with the part during the ejection process, thus reducing the resistance of the ejection step and reducing the occurrence of part defects such as white marks, thereby lowering the probability of defective products.

[0025] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0026] This application discloses an injection mold for automotive grilles.

[0027] Reference Figure 1 , Figure 2 An injection mold for an automotive grille includes a support platform 1. A horizontal opening and closing mechanism 2 is provided inside the support platform 1 for opening the mold horizontally on both sides. A lifting mechanism 3 is provided inside the support platform 1 for ejecting the mold. A sliding column 4 is fixedly connected to the top of the horizontal opening and closing mechanism 2. A moving mold base 6 is provided on the inner wall of the horizontal opening and closing mechanism 2. An inner mold 5 is provided inside the horizontal opening and closing mechanism 2 for shaping the internal shape of the part. The outer wall of the sliding column 4 movably penetrates the top of the moving mold base 6. An injection port is provided on the side wall of the moving mold base 6. An injection channel is provided inside the moving mold base 6. The horizontal opening and closing mechanism 2 includes a movable frame 212 located on the top of the support platform 1.

[0028] During the parts removal process, the worker first raises the moving mold base 6 vertically, then drives the cylinder 22, which in turn drives the horizontal opening and closing mechanism 2 to operate, causing the movable frame 212 to move horizontally to both sides and open. Then, the horizontal opening and closing mechanism 2 drives the lifting mechanism 3 to push the parts out, thus completing the injection molding of the parts.

[0029] Reference Figure 5 , Figure 6The horizontal opening and closing mechanism 2 includes a stationary mold base 21, an inner mold 5 fixedly connected to the top of the stationary mold base 21, and the stationary mold base 21 fixedly connected to the top of the support platform 1. The stationary mold base 21 is kept horizontal. A cavity is opened inside the stationary mold base 21. A cylinder 22 is fixedly connected to the bottom of the stationary mold base 21. The output shaft end of the cylinder 22 passes through the bottom of the stationary mold base 21. A horizontal plate 23 is fixedly passed through the output shaft end of the cylinder 22. A round hole is opened at the top of the horizontal plate 23. The output shaft end of the cylinder 22 is fixedly passed through the round hole. Both horizontal ends of plate 23 are fixedly connected to linkage components. The linkage components include support 1 24. The fixed end of support 1 24 is fixedly connected to both horizontal ends of horizontal plate 23. The movable end of support 1 24 is rotatably connected to connecting rod 25. The movable end of support 1 24 is horizontally fixedly connected to shaft. The shaft is rotatably connected to connecting rod 25. The end of connecting rod 25 away from support 1 24 is rotatably connected to support 26. The movable end of support 26 is rotatably connected to connecting rod 25. The fixed end of support 26 is fixedly connected to sliding component.

[0030] When cylinder 22 is activated, cylinder 22 will drive horizontal plate 23 to move vertically. When horizontal plate 23 moves vertically, horizontal plate 23 will drive support 24 to move vertically in sync. The vertical movement of support 24 will drive support 26 to move horizontally through connecting rod 25.

[0031] Reference Figure 4 , Figure 5 The sliding assembly includes a sliding plate 27 fixedly connected to the fixed end of the support 26. The sliding plate 27 is kept horizontal. A groove is provided on the side wall of the stationary mold base 21. The sliding plate 27 is slidably connected to the groove. A fixing block 28 is fixedly connected to the bottom of the sliding plate 27. A horizontal column 29 is movably passed through the side wall of the fixing block 28. A round hole is provided on the side wall of the fixing block 28. The round hole 29 is slidably connected to the horizontal column 29. A vertical plate 210 is fixedly connected to the end of the fixing block 28. The vertical plate 210 is kept vertical. The end of the horizontal column 29 away from the vertical plate 210 is fixedly connected to the inner wall of the stationary mold base 21. The horizontal column 29 is kept horizontal. The horizontal column 29 is slidably connected to the fixing block 28. The bottom of the vertical plate 210 is fixedly connected to the bottom of the inner wall of the stationary mold base 21. A synchronization assembly is fixedly connected to the top of the sliding plate 27.

[0032] When the second support 26 moves horizontally, the second support 26 will drive the sliding plate 27 to move horizontally in sync. The sliding plate 27 will drive the fixed block 28 to move horizontally in sync. The fixed block 28 is limited by the horizontal column 29, thus keeping the sliding plate 27 in a horizontal state at all times.

[0033] Reference Figure 3 , Figure 4The synchronization component includes a sliding block 211, the bottom of which is fixedly connected to the top of the sliding plate 27. A second sliding groove is provided on the top of the stationary mold base 21, and the sliding block 211 is slidably connected to the second sliding groove, thereby making the sliding block 211 slidably connected to the stationary mold base 21. The side wall of the sliding block 211 is embedded and fixedly fixed to the movable frame 212. The surface of the sliding block 211 is flush with the surface of the sliding block 212. A fixed frame 213 is fixedly connected to the top of the stationary mold base 21, which is engaged with the movable frame 212. The bottom of the fixed frame 213 is fixedly connected to the top of the stationary mold base 21.

[0034] The horizontal movement of the sliding plate 27 will drive the sliding block 211 to move horizontally, and the horizontal movement of the sliding block 211 will drive the movable frame 212 to move horizontally, thereby causing the movable frame 212 to separate from the fixed frame 213, thereby causing the inner wall of the movable frame 212 to separate from the part, thus completing the movement step.

[0035] Reference Figure 5 , Figure 6 The lifting mechanism 3 includes a limiting plate 31 fixedly passing through the output shaft of the cylinder 22. The limiting plate 31 is vertically symmetrically located on the outer wall of the output shaft of the stationary mold base 21. A synchronization plate 32 is movably passing through the outer wall of the output shaft of the cylinder 22. The synchronization plate 32 is kept horizontal. Vertical bars 33 are fixedly connected to both horizontal ends of the synchronization plate 32. The vertical bars 33 are perpendicular to the horizontal of the synchronization plate 32. Vertical members 34 are fixedly connected to both horizontal ends of the vertical bars 33. The vertical members 34 are kept vertical. A square hole is opened through the top of the stationary mold base 21. The vertical members 34 are slidably connected to the square hole. A sliding frame 35 is fixedly connected to the top of the vertical members 34. The inner and outer walls of the sliding frame 35 are slidably connected to the stationary mold base 21.

[0036] After the movable frame 212 completes the movement step, the output shaft of the cylinder 22 will also drive the limiting plate 31 to move vertically upward. The limiting plate 31 will drive the synchronous plate 32 to move vertically upward. The synchronous plate 32 will drive the vertical bar 33 to move vertically. The vertical bar 33 will drive the vertical component 34 to move vertically, thereby causing the vertical component 34 to drive the sliding frame 35 to move vertically, thereby separating the part from the mold and completing the injection molding step.

[0037] The implementation principle of an automotive grille injection mold according to an embodiment of this application is as follows: During the parts removal process, the worker first raises the moving mold base 6 vertically, then drives the cylinder 22, which drives the horizontal opening and closing mechanism 2 to operate, causing the movable frame 212 to move horizontally to both sides and open. Then the horizontal opening and closing mechanism 2 drives the lifting mechanism 3 to push the parts out. When the cylinder 22 is activated, it drives the movable frame 212 to move horizontally, thus separating the movable frame 212 from the fixed frame 213, thereby separating the inner wall of the movable frame 212 from the parts.

[0038] After the movable frame 212 completes the movement step, the output shaft of the cylinder 22 will also drive the limiting plate 31 to move vertically upward. The limiting plate 31 will drive the synchronous plate 32 to move vertically upward. The synchronous plate 32 will drive the vertical bar 33 to move vertically. The vertical bar 33 will drive the vertical component 34 to move vertically, thereby causing the vertical component 34 to drive the sliding frame 35 to move vertically, thereby separating the part from the mold and completing the injection molding step. This reduces the wrapping of the part when the sliding frame 35 ejects the part, resulting in fewer surface defects after the part leaves the mold.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
