Description

Technical Field

[0001] This invention relates to the field of injection mold technology, and in particular to an injection mold for automotive headlights that is easy to assemble and disassemble quickly. Background Technology

[0002] Automotive headlight injection molds are injection molding tools used to manufacture automotive headlights. They can process plastic materials into various headlight parts, such as headlight housings and reflectors, through injection molding. Specifically, automotive headlight injection molds typically include mold cavities, cores, gating systems, cooling systems, and ejection systems. The gating system injects the material into the mold cavity to form the required headlight parts. Finally, the ejection system ejects the molded parts from the mold, completing the entire injection molding process.

[0003] However, in practical applications, traditional injection mold technology still has some problems: 1. When different injection molded products require the replacement of the corresponding mold core, the current mold core and ejector pin are independently installed on the mold base by bolts. The replacement process requires disassembling and assembling each part one by one, which is cumbersome and there is room for efficiency optimization. 2. During the injection molding process, the moving mold and the fixed mold are installed on both sides of the injection molding machine. After long-term use, there may be a slight offset in their relative positions. If this is not detected in time, it may lead to poor mold closing and the formation of gaps, or even collision damage to the mold core. At present, there is a lack of effective offset monitoring and adaptive centering structure. 3. During the demolding and ejection stage, the injection molding machine drives the ejector pin directly, and the ejector pin action lacks a buffer mechanism. When the adhesion between the injection molded part and the mold core is large, forced ejection can easily cause local cracking or damage to the injection molded part, affecting the product molding quality. Summary of the Invention

[0009] Preferably, a locking mechanism is connected to the bottom mold core. The locking mechanism includes a locking bolt, through which the locking bolt is movably inserted. The end of the locking bolt movably inserts through the bottom frame. A locking nut is threaded onto one end of the locking bolt that passes through the bottom frame. A pressure ring is sleeved between the locking bolt, the locking nut, and the bottom frame. Multiple balls are installed on one side of the pressure ring, and the ends of the balls abut against the bottom frame.

[0010] Preferably, a mounting plate is installed on the bottom frame, the telescopic displacement sensor is mounted on the mounting plate, a second piston cylinder is mounted on the mounting plate, the second piston cylinder is stepped, a second piston rod and a third piston rod are slidably connected to both ends of the second piston cylinder, the diameter of the second piston rod is larger than that of the third piston rod, a fixing rod is installed between the third piston rod and the telescopic end of the telescopic displacement sensor, a slider is slidably connected to the mounting plate, a connecting rod is rotatably connected between the slider and the transmission rod, and one end of the second piston rod is fixedly connected to the slider.

[0011] Preferably, both the base frame and the top frame are connected to a limiting assembly, the limiting assembly including a pressure rod, both the base frame and the top frame are rotatably connected to the pressure rod, the pressure rod is threaded with a limiting bolt, the base frame and the top frame are respectively threadedly screwed to the limiting bolt at the same end, the pressure rod is threaded with an abutting bolt, and the base frame and the top frame respectively abut against the end of the abutting bolt at the same end.

[0012] Preferably, a plurality of guide rods are mounted on the base plate, and the same abutment plate is slidably connected to the plurality of guide rods, the end of the abutment plate abutting against the end of the first piston rod.

[0013] Preferably, the bottom mold core is connected to an abutment mechanism, the abutment mechanism includes a protrusion, the bottom mold core is fixedly connected to the side near the top mold core, the top mold core is provided with an abutment groove corresponding to the protrusion, and the protrusion is hemispherical.

[0014] Preferably, the top frame is equipped with multiple sliding rods, and the base frame is provided with grooves corresponding to the sliding rods, and the sliding rods are inserted into the base frame.

[0015] Compared with the prior art, the present invention provides an automotive headlight injection mold that is easy to assemble and disassemble quickly, and has the following beneficial effects: 1. This automotive headlight injection mold, which is easy to disassemble and assemble quickly, allows for the rapid replacement of the bottom and top mold cores by pulling out the bottom and top frames from the base and top frames respectively and inserting new bottom and top frames. When misalignment occurs between the bottom and top mold cores, a protrusion extends into the contact groove during the mold closing process to correct the bottom mold core and align it with the top mold core. The bottom mold core presses one end of the rubber ring, and displacement compensation is achieved through the deformation of the rubber ring, ensuring the mold closing quality between the bottom and top mold cores and avoiding collisions due to misalignment.

[0016] 2. This automotive headlight injection mold, which facilitates quick assembly and disassembly, utilizes the injection molding machine's push rod to slide the first piston rod, compressing the first spring. The first piston rod moves into the first piston cylinder, allowing air inside the cylinder to be quickly expelled through a one-way valve. The second spring compresses, pushing the first piston cylinder and ejector pins towards the bottom mold core. The ejector pins then push the molded part away from the bottom mold core. When the molded part adheres firmly, the thrust applied by the ejector pins gradually increases with the movement of the first piston rod, increasing the compression of the second spring and thus the ejector pin thrust. This gradually separates the molded part from the bottom mold core, preventing damage from excessive force applied at once. Multiple ejector pins can work together, prioritizing the removal of easily detachable parts before completing the overall demolding with the assistance of other ejector pins, effectively ensuring demolding quality.

[0017] 3. This easy-to-disassemble automotive headlight injection mold, during use, when misalignment occurs between the bottom mold core and the top mold core, the bottom mold core drives the transmission rod to move. The transmission rod drives the slider to move through the connecting rod. The slider drives the second piston rod to move. Since the diameter of the second piston rod is larger than that of the third piston rod, the displacement of the second piston rod is amplified, and the movement distance of the third piston rod is correspondingly increased. This causes the telescopic displacement sensor to be pulled by the fixed rod, thereby converting the movement of the bottom mold core into an electrical signal. By connecting to a computer, the movement of the bottom mold core can be monitored, facilitating timely correction by the staff. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0022] Example 1: Refer to Figures 1-12 An easy-to-assemble and disassemble automotive headlight injection mold includes a base plate 1 and a top plate 2. A mold closing mechanism 3 is connected between the base plate 1 and the top plate 2. The mold closing mechanism 3 includes a base frame 32 and a top frame 33. The base frame 32 and the top frame 33 are respectively mounted on the base plate 1 and the top plate 2. A bottom frame 34 and a top frame 36 are respectively inserted into the base frame 32 and the top frame 33. A movable bottom mold core 38 is inserted into the bottom frame 34. Rubber is used to abut between the bottom frame 34 and the bottom mold core 38. The top frame 36 is equipped with a top mold core 37. When the bottom mold core 38 and the top mold core 37 need to be replaced, the bottom frame 34 and the top frame 36 are pulled out from the base frame 32 and the top frame 33. The bottom mold core 38 and the top mold core 37 are connected to the bottom frame 34 and the top frame 36 respectively, thereby causing the bottom mold core 38 and the top mold core 37 to detach. The new bottom frame 34 and the top frame 36 are then inserted, which can achieve quick replacement of the bottom mold core 38 and the top mold core 37 and make disassembly convenient.

[0023] In this invention, a locking mechanism 6 is connected to the bottom mold core 38. The locking mechanism 6 includes a locking bolt 61, through which the locking bolt 61 movably passes. The end of the locking bolt 61 movably passes through the bottom frame 34. A locking nut 62 is threaded onto one end of the locking bolt 61 that passes through the bottom frame 34. A pressure ring 63 is sleeved between the locking bolt 61, the locking nut 62, and the bottom frame 34. A plurality of balls 64 are installed on one side of the pressure ring 63, and the ends of the balls 64 abut against the bottom frame 34. The locking bolt 61 secures the bottom mold core 38 and the bottom frame 34. The bottom frame 34 is locked together, and the rubber ring 39 provides space for the bottom mold core 38 to move, ensuring stable mold closing between the bottom mold core 38 and the top mold core 37 and avoiding deviation. When deviation occurs, the bottom mold core 38 moves to one end, causing the rubber ring 39 to be squeezed and deformed. During mold separation, the rubber ring 39 pushes the bottom mold core 38 back to its original position, so that the bottom mold core 38 is in the middle of the bottom frame 34 when subsequent workers perform correction. The ball bearing 64 enables the pressure ring 63 to move smoothly, reducing resistance and facilitating the movement of the bottom mold core 38.

[0024] In this invention, both the base frame 32 and the top frame 33 are connected to a limiting component 35. The limiting component 35 includes a pressure rod 351. The pressure rod 351 is rotatably connected to both the base frame 32 and the top frame 33. A limiting bolt 353 is threaded onto the pressure rod 351. The base frame 32 and the top frame 33 are respectively threadedly connected to the limiting bolt 353 at the same end. An abutting bolt 352 is threaded onto the pressure rod 351. The base frame 32 and the top frame 33 respectively abut against the end of the abutting bolt 352 at the same end. The pressure rod 351 limits the bottom frame 34 and the top frame 36, and the abutting bolt 352 fastens the bottom frame 34 and the top frame 36 to prevent movement.

[0025] In this invention, a contact mechanism 9 is connected to the bottom mold core 38. The contact mechanism 9 includes a protrusion 91. The protrusion 91 is fixedly connected to the side of the bottom mold core 38 near the top mold core 37. The top mold core 37 is provided with a contact groove 92 corresponding to the protrusion 91. The protrusion 91 is hemispherical. The bottom mold core 38 and the top mold core 37 can be accurately molded by the cooperation of the protrusion 91 and the contact groove 92. When an offset occurs, the bottom mold core 38 can be driven to move.

[0026] In this invention, a plurality of sliding rods 31 are installed on the top frame 33, and the bottom frame 32 is provided with grooves corresponding to the sliding rods 31. The sliding rods 31 are inserted into the bottom frame 32, and the bottom frame 32 can be aligned with the top frame 33 through the sliding rods 31.

[0027] Example 2: Based on Example 1, an injection mold for automotive headlights that is easy to assemble and disassemble is provided. An ejector mechanism 4 is connected to the bottom mold core 38. A through ejector pin 44 is slidably connected to the bottom mold core 38. A first piston cylinder 49 is installed at one end of the ejector pin 44. A first piston rod 42 is slidably connected to one end of the first piston cylinder 49. An air hole 47 is provided on the side wall of the first piston cylinder 49. A first spring 41 is connected between the first piston rod 42 and the bottom mold core 38. Air resistance is generated through the air hole 47 to slow down the movement speed of the first piston cylinder 49 and the ejector pin 44, thereby preventing the ejector pin 44 from forcibly pushing out the injection molded part.

[0028] In this invention, a second spring 48 is installed between the first piston rod 42 and the first piston cylinder 49. A one-way valve 46 is installed on the side wall of the first piston cylinder 49. The one-way valve 46 allows the air inside the first piston cylinder 49 to be discharged quickly. The second spring 48 forms resistance. When the injection molded part is ejected, the air hole 47 slows down the speed at which external air enters the first piston cylinder 49. This prevents the first piston cylinder 49 and the ejector pin 44 from moving rapidly under the release of the second spring 48 when the ejector pin 44 loses resistance, thus avoiding damage to the injection molded part.

[0029] In this invention, an mounting rod 43 is installed on the bottom mold core 38, and the ejector pin 44 slides through the mounting rod 43. A first spring 41 is installed between the first piston rod 42 and the mounting rod 43, and the mounting rod 43 guides the ejector pin 44 to ensure stable sliding of the ejector pin 44.

[0030] In this invention, an anti-detachment component 45 is connected to the mounting rod 43. The anti-detachment component 45 includes a pin block 451. The pin block 451 is threaded onto the mounting rod 43. The ejector pin 44 is provided with a guide groove 453. One end of the pin block 451 extends into the guide groove 453. A top cap 452 is threaded onto the end of the first piston cylinder 49 near the first piston rod 42. The end of the first piston rod 42 moves through the top cap 452. The pin block 451 limits the ejector pin 44 to prevent the ejector pin 44 from detaching from the bottom mold core 38.

[0031] In this invention, a plurality of guide rods 8 are installed on the base plate 1, and the same abutment plate 7 is slidably connected to the plurality of guide rods 8. The end of the abutment plate 7 abuts against the end of the first piston rod 42, and the first piston rod 42 is pushed more stably by pushing the abutment plate 7.

[0032] Example 3: Based on Example 2, an automotive headlight injection mold that is easy to assemble and disassemble is provided. A monitoring mechanism 5 is connected to the bottom mold core 38. The monitoring mechanism 5 includes a transmission rod 52. The transmission rod 52 is installed on the bottom mold core 38. A telescopic displacement sensor 56 is connected to the bottom frame 34. The telescopic end of the telescopic displacement sensor 56 is connected to the transmission rod 52. The movement of the bottom mold core 38 is monitored by the telescopic displacement sensor 56.

[0033] In this invention, a mounting plate 51 is installed on the base frame 34, and a telescopic displacement sensor 56 is installed on the mounting plate 51. A second piston cylinder 57 is installed on the mounting plate 51. The second piston cylinder 57 is stepped, and a second piston rod 55 and a third piston rod 58 are slidably connected to its two ends, respectively. The diameter of the second piston rod 55 is larger than that of the third piston rod 58. A fixing rod 59 is installed between the third piston rod 58 and the telescopic end of the telescopic displacement sensor 56. A slider 54 is slidably connected to the mounting plate 51, and a connecting rod 53 is rotatably connected between the slider 54 and the transmission rod 52. One end of the second piston rod 55 is fixedly connected to the slider 54. Since the diameter of the second piston rod 55 is larger than that of the third piston rod 58, the displacement of the second piston rod 55 is amplified. When the second piston rod 55 is pushed, the distance that the third piston rod 58 moves will increase, thereby facilitating detection by the telescopic displacement sensor 56.

[0034] Working principle: The base plate 1 and top plate 2 are installed on the injection molding machine. When it is necessary to disassemble and replace the mold core, the limit bolt 353 is turned by wrench to release the limit on the pressure rod 351. The pressure rod 351 is rotated outward, and the bottom frame 34 and top frame 36 are pulled out from the base frame 32 and top frame 33 respectively. The bottom mold core 38 and top mold core 37 are connected to the bottom frame 34 and top frame 36 respectively, thereby causing the bottom mold core 38 and top mold core 37 to disengage. The new bottom frame 34 and top frame 36 are then inserted. To enable quick replacement of the bottom mold core 38 and the top mold core 37, rotate the pressure rod 351 to limit the bottom frame 34 and the top frame 36, rotate the limit bolt 353 to lock the pressure rod 351, and rotate the abutment bolt 352 to press the bottom frame 34 and the top frame 36 together to prevent them from shaking. When the mold is closed, push the base plate 1 to move, which drives the base frame 32 to move towards the top frame 33. The slide rod 31 is inserted into the base frame 32, and the bottom mold core 38 and the top mold core 37 are closed. The protrusion 91 extends into the contact groove 92. A rubber ring 39 abuts between the bottom mold core 38 and the bottom frame 34. With prolonged use, when misalignment occurs between the bottom mold core 38 and the top mold core 37, the protrusion 91 extends into the contact groove 92 to correct the bottom mold core 38. The bottom mold core 38 moves, aligning with the top mold core 37. The bottom mold core 38 presses one end of the rubber ring 39, and displacement compensation is achieved through the deformation of the rubber ring 39, ensuring the alignment of the bottom mold core 38 and the top mold core 37. The mold closing quality between 7 is such that when the bottom mold core 38 moves, it drives the locking bolt 61 to move, and the locking bolt 61 drives the pressure ring 63 to move. The pressure ring 63 abuts against the base frame 32 through the ball bearing 64, thereby reducing the resistance when the bottom mold core 38 moves. The top mold core 37 is provided with an injection port at its end, so that injection molding can be performed through one end of the top mold core 37. Cooling water pipes are installed on the bottom mold core 38 and the top mold core 37 to cool down the bottom mold core 38 and the top mold core 37 and promote the solidification of the glue. During demolding, the base plate 1 is pulled to separate the bottom mold core 38 and the top mold core 37. The injection molded part adheres to the bottom mold core 38. The injection molding machine's push rod is activated, pushing the contact plate 7. The contact plate 7 slides along the guide rod 8, pushing the first piston rod 42 to slide. The first spring 41 is compressed, and the first piston rod 42 moves into the first piston cylinder 49. The air inside the first piston cylinder 49 is quickly discharged outward through the one-way valve 46. The second spring 48 is compressed, pushing the first piston cylinder 49 and the ejector pin 44 towards the bottom mold core 38. The ejector pin 44 pushes the injection molded part away from the bottom mold core 38. When the injection molded part is firmly adhered, the thrust applied by the ejector pin 44 to the injection molded part increases with the movement of the first piston rod 42 and the compression of the second spring 48, gradually increasing the thrust of the ejector pin 44. The injection molded part gradually separates from the bottom mold core 38 to avoid excessive force applied at once, which could damage the injection molded part. When multiple ejector pins 44 are set, they can work together to peel off the parts of the injection molded part that are easy to detach first, and then complete the overall demolding with the help of other ejector pins 44. After the injection molded part separates from the bottom mold core 38, the ejector pins 44 lose resistance, and the compressed second spring 48 pushes the first piston cylinder 49 and ejector pins 44 to move. External gas slowly enters the first piston cylinder 49 through the air hole 47, thereby forming air resistance, slowing down the extension of the second spring 48 and the movement speed of the first piston cylinder 49 and ejector pins 44, and preventing the ejector pins 44 from damaging the injection molded part due to resistance. The surface of the automotive headlight injection molded part is smooth and without clips. The method of prioritizing the peeling off of the easy-to-peel parts effectively ensures the demolding quality. During use, when a misalignment occurs between the bottom mold core 38 and the top mold core 37, the bottom mold core 38 moves, causing the transmission rod 52 to move. The transmission rod 52, through the connecting rod 53, drives the slider 54 to move. The slider 54 then drives the second piston rod 55 to move. Since the diameter of the second piston rod 55 is larger than that of the third piston rod 58, the displacement of the second piston rod 55 is amplified, and the movement distance of the third piston rod 58 increases accordingly. This causes the telescopic end of the telescopic displacement sensor 56 to be pulled by the fixed rod 59, thereby converting the movement of the bottom mold core 38 into an electrical signal. By connecting to a computer, the displacement of the bottom mold core 38 can be calculated, facilitating timely correction by the staff.

[0035] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
