Description

Technical Field

[0001] This application relates to the field of injection mold technology, specifically to injection molds for automotive headlight housings. Background Technology

[0002] Utility model patent CN221622930U discloses a high-precision, fast-heat-dissipating injection mold for automotive headlight housings. It includes a support base, a cooling tank with interconnected circulation conduits on both the front and rear sides, a screw cap rotatably mounted on one end of each conduit, and a cooling box connected to the other end, which is fixedly connected to both sides of a mounting frame. This high-precision, fast-heat-dissipating injection mold allows coolant from the cooling box to be circulated into the cooling tank via the circulation conduits for rapid cooling, resulting in excellent cooling performance. The limiting lifting groove and sliding ball joints stabilize the upper mold's lifting and lowering. Sealing is achieved through sealing blocks and grooves, and the injection pipes are clamped and positioned by clamping blocks for more stable injection. The mounting frame is easy to assemble and disassemble using mounting blocks, locking knobs, and mounting grooves, facilitating quick replacement of the upper and lower molds. However, this device has some shortcomings in use: the headlight housing adheres to the lower mold, making demolding difficult; and the mold and headlight housing are closely fitted, making separation inconvenient. Utility Model Content

[0003] The purpose of this utility model is to provide an injection mold for automotive headlight housings, which solves the problems of headlight housings adhering to the lower mold, making demolding inconvenient, and the mold and headlight housings being too close together, making separation difficult.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an injection mold for automotive headlight housings, comprising a frame, a lower mold fixedly mounted on the surface of the frame, a cylinder fixedly mounted at the upper middle part of the frame, a cylinder rod passing through the frame and slidably connected to the frame, a hanger fixedly connected to the lower end of the cylinder rod, an upper mold fixedly connected to the lower end of the hanger, the upper mold and the lower mold contacting each other, an ejection mechanism provided on the upper mold, and a stripping mechanism provided on the upper mold.

[0005] Preferably, the ejection mechanism includes a support plate, with the support plate fixedly connected to the surface of the upper mold. A hanger rod is slidably connected inside the support plate, a pressure plate is fixedly connected to the outside of the hanger rod, and a spring is provided on the outside of the hanger rod. The hanger rod and the frame are slidably connected, a connecting plate is fixedly connected to the lower end of the hanger rod, and a top rod is fixedly connected to the upper end of the connecting plate. The top rod and the lower mold are slidably connected. A cylinder drives the hanger to move the upper mold, which in turn causes the support plate to move via the hanger rod, which in turn causes the top rod to move the top ring. This allows the headlight housing to be lifted, facilitating separation between the headlight housing and the lower mold, and making demolding easier.

[0006] Preferably, one end of the spring is fixedly connected to the support plate, and the other end of the spring is fixedly connected to the pressure plate. By setting the spring, the pressure plate is elastically pressed down.

[0007] Preferably, a top ring is fixedly connected to the upper end of the top rod, and the top ring is slidably connected to the lower mold. By setting the top ring, the headlight housing is pushed upwards.

[0008] Preferably, the stripping mechanism includes a forming mold, with a forming mold slidably connected inside the upper mold, the forming mold contacting the lower mold, a guide rod fixedly connected to the surface of the upper mold, the guide rod slidably connected to the forming mold, a compression spring provided on the outer side of the guide rod, a motor fixedly mounted at the upper end of the upper mold, the motor's shaft passing through the upper mold and rotatably connected to the upper mold, a rotating ring fixedly connected to the lower end of the motor's shaft, and a wedge fixedly connected to the surface of the rotating ring. The motor drives the rotating ring to rotate, causing the wedge to move and engage with the stop block, thereby causing the forming mold to move upwards and slide into the upper mold, thus facilitating separation between the forming mold and the headlight housing.

[0009] Preferably, one end of the compression spring is fixedly connected to the upper mold, and the other end of the compression spring is fixedly connected to the forming mold. By setting the compression spring, the forming mold is elastically pressed down.

[0010] Preferably, a stop block is fixedly connected inside the mold, and the stop block and the inclined block are slidably connected. By setting the stop block and the inclined block to cooperate, the mold can be easily moved and adjusted.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model uses a cylinder to drive the hanger to move the upper mold, which in turn causes the support plate to move the connecting plate through the hanger rod, which in turn causes the top rod to move the top ring. This allows the headlight housing to be lifted, making it easier to separate the headlight housing from the lower mold and making demolding the device more convenient.

[0013] 2. This utility model uses a motor to drive the rotating ring to move the inclined block and cooperate with the stop block, thereby causing the mold to move upward and slide into the upper mold, thus making it easy to separate the mold and the car headlight housing.

[0020] Please see Figures 1-2 An injection mold for an automotive headlight housing includes a frame 1, a lower mold 2 fixedly mounted on the surface of the frame 1, a cylinder 3 fixedly mounted on the upper middle part of the frame 1, a cylinder rod of the cylinder 3 passing through the frame 1 and slidably connected to the frame 1, a hanger 4 fixedly connected to the lower end of the cylinder rod of the cylinder 3, an upper mold 5 fixedly connected to the lower end of the hanger 4, the upper mold 5 and the lower mold 2 are in contact, an ejection mechanism 6 is provided on the upper mold 5, and a stripping mechanism 7 is provided on the upper mold 5.

[0021] Please see Figures 1-2 The ejection mechanism 6 includes a support plate 61. The support plate 61 is fixedly connected to the surface of the upper mold 5. A lifting rod 62 is slidably connected inside the support plate 61. A pressure plate 63 is fixedly connected to the outside of the lifting rod 62. A spring 64 is provided on the outside of the lifting rod 62. One end of the spring 64 is fixedly connected to the support plate 61, and the other end of the spring 64 is fixedly connected to the pressure plate 63. By setting the spring 64, the pressure plate 63 is elastically pressed down. The lifting rod 62 is slidably connected to the frame 1. A connecting plate 65 is fixedly connected to the lower end of the lifting rod 62. A top rod 66 is fixedly connected to the upper end, and the top rod 66 is slidably connected to the lower mold 2. A top ring 67 is fixedly connected to the upper end of the top rod 66, and the top ring 67 is slidably connected to the lower mold 2. By setting the top ring 67, the headlight housing is pushed upward. The cylinder 3 drives the hanger 4 to move the upper mold 5, which in turn causes the support plate 61 to move the connecting plate 65 through the hanger 62. This, in turn, causes the top rod 66 to move the top ring 67, which can push the headlight housing upward, making it easier to separate the headlight housing from the lower mold 2 and making demolding of the device more convenient.

[0022] Please see Figures 1-2The unloading mechanism 7 includes a forming mold 71. The forming mold 71 is slidably connected inside the upper mold 5 and contacts the lower mold 2. A guide rod 72 is fixedly connected to the surface of the upper mold 5 and slidably connected to the forming mold 71. A compression spring 73 is provided on the outside of the guide rod 72. One end of the compression spring 73 is fixedly connected to the upper mold 5, and the other end of the compression spring 73 is fixedly connected to the forming mold 71. By providing the compression spring 73, the forming mold 71 is elastically pressed down. A motor 74 is fixedly installed at the upper end of the upper mold 5. The rotating shaft of the motor 74 passes through the upper mold 5 and is connected to the upper mold. 5. Rotary connection: A rotating ring 75 is fixedly connected to the lower end of the rotating shaft of the motor 74. An inclined block 76 is fixedly connected to the surface of the rotating ring 75. A stop block 77 is fixedly connected to the inside of the mold 71. The stop block 77 and the inclined block 76 are slidably connected. By setting the stop block 77 and the inclined block 76 to cooperate, the mold 71 can be easily moved and adjusted. The rotating ring 75 is driven by the motor 74 to rotate, which drives the inclined block 76 to move and cooperate with the stop block 77, thereby causing the mold 71 to move upward and slide into the upper mold 5, thereby making it easy to separate the mold 71 from the headlight housing.

[0023] The specific implementation process of this utility model is as follows: In use, the cylinder 3 is activated, driving the cylinder rod to extend. The cylinder rod moves the hanger 4, which in turn moves the upper mold 5. The upper mold 5 moves and contacts the lower mold 2. Simultaneously, the movement of the upper mold 5 causes the support plate 61 to move, compressing the spring 64. This causes the spring 64 to compress the pressure plate 63, which in turn causes the hanger 62 to move the connecting plate 65. The connecting plate 65 then moves the push rod 66, pressing the top ring 67 tightly within the lower mold 2. This is achieved through the injection molding process on the upper mold 5. After injection molding, cylinder 3 is activated to drive the hanger 4 to move, which in turn moves the upper mold 5, which in turn moves the support plate 61 to drive the hanger 62 to move, which in turn moves the top ring 67 to lift the headlight housing, making it easier to separate the headlight housing from the lower mold 2. Then, motor 74 is activated, which drives the rotating ring 75 to rotate, which moves the inclined block 76 and cooperates with the stop block 77, which in turn moves the mold 71 to slide into the upper mold 5, making it easier to separate the mold 71 from the headlight housing.
