Description

Technical Field

[0001] This invention relates to the field of injection molding machine technology, and more specifically to an injection molding machine that facilitates the unloading of automotive interior molded parts. Background Technology

[0002] Injection molding machines, also known as injection molding machines or injection molding machines, are the main molding equipment used to produce various shapes of plastic products from thermoplastic or thermosetting plastics using plastic molds. They are classified as vertical, horizontal, and all-electric. Injection molding machines heat new plastic raw materials or recycled defective plastic raw materials, apply high pressure to the molten plastic, and inject it to fill the mold cavity.

[0003] In existing injection molding machines, the molded parts can automatically fall downwards and be discharged through the movement of the mold itself. However, when the molded interior parts are large or heavy, the interior parts can easily collide with the inner cavity of the machine body when they fall downwards, causing damage to the surface of the interior parts, affecting the product quality and reducing the yield rate. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and to propose an injection molding machine that facilitates the cutting of automotive interior molding parts.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An injection molding machine for facilitating the unloading of automotive interior molded parts includes a machine body. A housing is mounted on the top of the machine body. A moving mold and a stationary mold are arranged inside the housing. The stationary mold is mounted on the inner wall of one side of the housing. Multiple telescopic columns are installed inside the housing. The telescopic ends of the multiple telescopic columns are each threaded with a mounting seat by multiple bolts. The mounting seat and the moving mold are connected by a material ejector device. A material ejector port communicating with the housing is opened on the top of the machine body. A cavity is opened inside the machine body. A material ejector mechanism for assisting the unloading of injection-molded parts is arranged inside the cavity. The material ejector mechanism includes a second moving plate arranged inside the cavity. Two clamping plates are mounted on the top of the second moving plate. Auxiliary guiding mechanisms for guiding the injection-molded parts between the two clamping plates are installed on the outer walls of both sides of the clamping plates.

[0007] Optionally, a feed hopper is installed on the top of the machine body, and a material cylinder is installed below the feed hopper. The nozzle at the output end of the material cylinder is connected to the stationary mold.

[0008] Optionally, the inner bottom surface of the cavity is provided with two first sliding grooves, each of which is equipped with a first slider, and the top of the two first sliders is jointly equipped with a first movable plate.

[0009] Optionally, the top of the first movable plate has two first grooves, and a double-ended screw is rotatably installed inside each of the two first grooves. Two movable blocks are installed on the outer walls of each of the two double-ended screws.

[0010] Optionally, a second rotating block is rotatably mounted on the top of each of the two movable blocks, and a plurality of first rotating blocks are rotatably mounted on the bottom of the second movable plate. The plurality of first rotating blocks and their corresponding second rotating blocks are connected by a first electric telescopic rod.

[0011] Optionally, the top of the second movable plate has two second slide grooves, and two second sliders are installed inside each of the two second slide grooves. The top of the two corresponding second sliders are jointly installed with a movable strip plate.

[0012] Optionally, a third sliding groove is provided on the top of each of the two movable strips, and a third slider is installed inside each of the two third sliding grooves. The bottom ends of the two clamps are respectively rotatably installed on the top of the corresponding third slider.

[0013] Optionally, the auxiliary guiding mechanism includes rotating plates rotatably mounted on both sides of the clamping plate, each rotating plate having a second groove inside, and each second groove having a retractable blind curtain installed inside.

[0014] Optionally, a connecting plate is installed at the end of each of the two curtains away from the second groove, and two electromagnets are installed inside each connecting plate.

[0015] Optionally, two sets of second electric telescopic rods are installed on the inner bottom surface of the cavity, and each set of second electric telescopic rods has a placement plate installed at its telescopic end.

[0016] The beneficial effects of this invention are:

[0017] 1. In this invention, the feeding mechanism guides, limits, and buffers the cooled and molded parts, preventing them from directly impacting the inner wall of the machine and causing damage. This protects the molded parts and indirectly improves the yield rate of injection molding. Furthermore, it automatically stacks the molded parts inside the cavity, facilitating subsequent handling and further improving the efficiency of injection molding feeding. This reduces the damage rate of parts, minimizing the need for recycling and reshaping damaged parts, and fully utilizing new or recycled defective plastic raw materials to ensure good injection molding quality.

[0018] 2. In this invention, if the component adheres to the surface of the moving mold after cooling and molding, and the ejector device cannot automatically push the component downward, the first moving plate is controlled to move multiple components above to a position close to the bottom of the moving mold, and the two clamping plates are controlled to move upward together until the two clamping plates are respectively located on both sides of the moving mold. The two clamping plates are used to clamp and fix the components attached to the surface of the moving mold. Then, the two third sliders are controlled to drive the two clamping plates to pull the components attached to the surface of the moving mold to the right until the attached components are pulled off the surface of the moving mold. There is no need to stop the machine and manually clean it to avoid affecting the injection molding efficiency of the components.

[0019] 3. In this invention, if it is necessary to disassemble and repair the mold or replace it with a new mold, the second moving plate is controlled to move upward until it abuts against the bottom of the moving mold and the stationary mold. At this time, the two clamping plates are located on both sides of the mold, and the two clamping plates abut tightly against the outer walls of the two sides of the mold, which has a clamping and fixing effect on the mold. Then, multiple electromagnets are controlled to be energized to generate magnetism, so that multiple connecting plates can be magnetically attracted and fixed to the outer walls of the moving mold and the stationary mold. As the extension ends of multiple first electric telescopic rods are controlled to extend upward, the second moving plate and the mold on its top are moved upward together to the top of the shell. With the double limiting and fixing of the two clamping plates and the electromagnets inside the multiple connecting plates, the safety and stability of the mold moving upward to the top of the shell are improved, and there is no need to manually disassemble the mold, thus improving the efficiency of mold disassembly and repair.

[0020] 4. In this invention, when a new mold is installed inside the housing, the second moving plate can be moved to the top of the housing by controlling the second moving plate. The new mold is placed on the top of the second moving plate and fixed by the double limiting of two clamping plates and multiple connecting plates. This makes the process of moving the mold into the housing safer and more stable. It also makes it easier for subsequent workers to quickly install the moving mold and the stationary mold without the need for additional hoisting or other fixing equipment, further improving the applicability of the feeding mechanism.

[0032] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Reference Figures 1-9An injection molding machine for facilitating the unloading of automotive interior molded parts includes a machine body 1. A housing 4 is mounted on the top of the machine body 1. A moving mold 6 and a stationary mold 5 are arranged inside the housing 4. The stationary mold 5 is mounted on the inner wall of one side of the housing 4. Multiple telescopic columns 8 are installed inside the housing 4. The telescopic ends of the multiple telescopic columns 8 are each threaded with a mounting seat 7 by multiple bolts. The mounting seat 7 and the moving mold 6 are connected by a material ejector device. A material discharge port 10 communicating with the housing 4 is opened on the top of the machine body 1. A cavity 9 is opened inside the machine body 1. A material discharge mechanism for assisting the unloading of injection-molded parts is arranged inside the cavity 9. The material discharge mechanism includes a second moving plate 14 arranged inside the cavity 9. Two clamping plates 15 are mounted on the top of the second moving plate 14. Auxiliary guiding mechanisms for guiding the injection-molded parts between the two clamping plates 15 are installed on the outer walls of both sides of the two clamping plates 15.

[0034] As a technical optimization of the present invention, a feeding hopper 2 is installed on the top of the machine body 1, and a material cylinder 3 is installed below the feeding hopper 2. The nozzle at the output end of the material cylinder 3 is connected to the stationary mold 5. The plastic raw material enters the interior of the material cylinder 3 through the feeding hopper 2 for heating and melting. Then, the material cylinder 3 discharges the melted plastic raw material through the nozzle into the interior of the stationary mold 5 and the moving mold 6 for injection molding. After a period of cooling, the moving mold 6 moves away from the stationary mold 5, so that the molded part automatically falls down from the inside of the mold into the interior of the cavity 9.

[0035] As a technical optimization of the present invention, two first sliding grooves 11 are formed on the inner bottom surface of the cavity 9. A first slider 16 is installed inside each of the two first sliding grooves 11, and a first moving plate 13 is installed at the top of both first sliders 16. A first linear motor is pre-installed inside each of the two first sliding grooves 11. The two first linear motors can drive the two first sliders 16 to move back and forth inside the corresponding first sliding grooves 11, thereby driving the first moving plate 13 to move back and forth on the inner bottom surface of the cavity 9.

[0036] As a technical optimization of the present invention, the top of the first movable plate 13 has two first grooves 28, and a double-ended screw 27 is rotatably installed inside each of the two first grooves 28. Two moving blocks 26 are installed on the outer walls of each of the two double-ended screws 27. Two first driving devices are preset on one side of the outer wall of the first movable plate 13. The output ends of the two first driving devices are respectively connected to one end of each of the two double-ended screws 27, thereby driving the two double-ended screws 27 to rotate inside the corresponding first grooves 28, allowing the two moving blocks 26 inside the two first grooves 28 to move and adjust towards or away from each other.

[0037] As a technical optimization of the present invention, a second rotating block 25 is rotatably mounted on the top of each of the two moving blocks 26, and a plurality of first rotating blocks 24 are rotatably mounted on the bottom of the second moving plate 14. The plurality of first rotating blocks 24 and their corresponding second rotating blocks 25 are connected by a first electric telescopic rod 23. When the two moving blocks 26 move toward each other, they can drive the two second rotating blocks 25 and the two first electric telescopic rods 23 to rotate together toward each other, thus pushing the upper second moving plate 14 upward slowly. Furthermore, the two first electric telescopic rods 23 can extend upwards, further driving the second moving plate 14 upwards. When the two moving blocks 26 move toward each other, they can drive the two second rotating blocks 25 and the two first electric telescopic rods 23 to rotate together toward each other, thus pulling the upper second moving plate 14 downwards slowly to its reset position, achieving the effect of automatic height adjustment of the second moving plate 14.

[0038] As a technical optimization of the present invention, the top of the second movable plate 14 has two second sliding grooves 22, and two second sliders 29 are installed inside each of the two second sliding grooves 22. The tops of the two corresponding second sliders 29 are jointly installed with a movable strip 17. A double-ended lead screw is preset inside each of the two second sliding grooves 22. The two double-ended lead screws cooperate with the two second sliders 29 respectively, and one end of each double-ended lead screw is connected to a preset output end of a second driving device. This allows the two double-ended lead screws to drive the two second sliders 29 to move towards or away from each other inside the corresponding second sliding grooves 22 during rotation, thereby driving the two movable strips 17 to move towards or away from each other on the top of the second movable plate 14.

[0039] As a technical optimization of the present invention, a third slide groove 30 is provided on the top of each of the two movable strips 17, and a third slider 31 is installed inside each of the two third slide grooves 30. The bottom ends of the two clamping plates 15 are respectively rotatably mounted on the top of the corresponding third slider 31. A third linear motor is preset inside each of the two third slide grooves 30, which can drive the two third sliders 31 to move back and forth inside the corresponding third slide grooves 30; and a third driving device is preset on one outer wall of each of the two third sliders 31. The output ends of the two third driving devices are respectively connected to the rotating parts of the two clamping plates 15, thereby enabling the two clamping plates 15 to rotate and adjust at the top of the corresponding third slider 31.

[0040] As a technical optimization of the present invention, the auxiliary guiding mechanism includes rotating plates 18 rotatably mounted on both sides of the clamping plate 15. Each of the two rotating plates 18 has a second groove 32 inside, and a retractable blind curtain 21 is installed inside each of the two second grooves 32. A first drive motor is pre-installed on the outer walls of both sides of the clamping plate 15. The output ends of the first drive motors are respectively connected to the rotating parts of the two rotating plates 18, thereby enabling the two rotating plates 18 to rotate and adjust on the outer walls of both sides of the clamping plate 15.

[0041] As a technical optimization of the present invention, each of the two curtain panels 21 has a connecting plate 19 installed at the end away from the second groove 32, and each of the two connecting plates 19 has two electromagnets 20 installed inside. When the two moving strips 17 move toward each other, they drive the two clamping plates 15 to move toward each other as well, and in turn drive the rotating plates 18 on both sides of the two clamping plates 15 to move together until the two sets of rotating plates 18 move to the abutting state. Then, by means of the electromagnets 20 installed inside the multiple connecting plates 19, they are magnetically attracted to each other, and then the two clamping plates 15 are controlled to move away from each other to reset, and the curtain panels 21 are pulled into an unfolded state, which facilitates the guidance of the falling parts, so that the two clamping plates 15 can accurately clamp and fix the parts.

[0042] As a technical optimization of the present invention, two sets of second electric telescopic rods 33 are installed on the inner bottom surface of the cavity 9, and each set of second electric telescopic rods 33 has a placement plate 12 installed at its telescopic end. When the telescopic ends of the two sets of second electric telescopic rods 33 extend, they can drive the two placement plates 12 to move outward from the inside of the cavity 9.

[0043] In this invention, when the user uses the device, the plastic raw material is fed into the inside of the barrel 3 through the feed hopper 2 for heating and melting. Then the barrel 3 discharges the melted plastic raw material through the nozzle into the inside of the stationary mold 5 and the moving mold 6 for injection molding. After a period of cooling, the moving mold 6 moves away from the stationary mold 5, so that the molded part automatically falls down from the inside of the mold into the inside of the cavity 9.

[0044] Because a feeding mechanism is installed inside cavity 9, during the cooling and molding process of the plastic raw material injected into the mold, refer to... Figure 4As shown, the two movable strips 17 can be controlled to move towards each other, driving the two clamping plates 15 and the two sets of rotating plates 18 to move towards each other until the two sets of rotating plates 18 move to the abutting state. Then, the electromagnets 20 inside the multiple connecting plates 19 are energized to generate magnetism, so that the two corresponding connecting plates 19 are magnetically attracted and fixed. Then, the two movable strips 17 are controlled to drive the two clamping plates 15 to move away from each other and reset. This causes the multiple second grooves 32 to unfold, and the multiple rotating plates 18 are controlled to rotate downwards away from the clamping plates 15 and tilt. After the parts inside the mold are cooled and formed, the moving mold 6 and the stationary mold 5 separate, and the parts are automatically pushed down by the set ejector device. The falling parts fall between the two sets of tilted rotating plates 18, and the multiple unfolded shielding curtains 21 guide and limit the parts, which can also have a flexible buffering effect on the parts.

[0045] After the component is positioned between the two clamping plates 15, multiple rotating plates 18 are controlled to rotate and reset towards the clamping plates 15, so that the component is in a vertical position between the two clamping plates 15. At the same time, the two clamping plates 15 are controlled to move towards each other, clamping and limiting the two ends of the vertical component. Then, the multiple rotating plates 18 can be controlled to rotate downward to a horizontal position, so that the component is now clamped and fixed by the two clamping plates 15. After the component is inspected by the appearance inspection equipment preset inside the machine body 1, if the component is qualified, the two first sliders 16 can be controlled to move the first moving plate 13 and its top multiple components together towards the left end to the vicinity of the placement plate 12 near the left side. The two clamping plates 15 are controlled to rotate to the left, and then the two third sliders 31 are controlled to move in the corresponding third slide grooves 30. The internal components slide towards the left, causing the two clamping plates 15 and the component to move together to the top of the left placement plate 12. The two clamping plates 15 are controlled to move away from each other, so that the component falls down onto the top of the two shielding curtains 21 on the left and is guided down along the top of the two downward-sloping shielding curtains 21 on the left, and is temporarily stored on the top of the left placement plate 12. If the component is unqualified, the two first sliders 16 are used to move multiple components towards the right, and the two clamping plates 15 are controlled to rotate to the right, so that the unqualified component is placed on the top of the right placement plate 12. This achieves the effect of flexible component unloading and automatic classification, avoiding the problem of components falling directly downward and easily being damaged on the surface, and can also indirectly improve the yield rate of the injection molded components.

[0046] Meanwhile, the components that subsequently fall between the two clamping plates 15 can be rotated by controlling the two double-headed screws 27 to drive the two corresponding moving blocks 26 to move slowly toward each other. This will cause the second moving plate 14 and the multiple components above it to move upward together, so that when the two clamping plates 15 rotate downward and place the components on top of the two placement plates 12, they can be stacked together one after another until enough components are stacked on top of the two placement plates 12. Then, the telescopic end of the second electric telescopic rod 33 is extended, causing the placement plate 12 to move out of the cavity 9. This will cause the stacked components to be automatically discharged from the cavity 9, making it convenient for staff to quickly pick up the components and improving the efficiency of component injection molding.

[0047] If, after the part has cooled and formed, the moving mold 6 separates from the stationary mold 5, and the part adheres to the surface of the moving mold 6, preventing the ejector device from automatically ejecting the part downwards, then after the moving mold 6 separates from the stationary mold 5, the first moving plate 13 can be controlled to move multiple parts above it to a position close to the bottom of the moving mold 6. The two double-headed screws 27 can be controlled to rotate, causing the second moving plate 14 and its two clamping plates 15 above it to move upwards together until the two clamping plates 15 are positioned on either side of the moving mold 6. Then, by moving the two clamping plates 15 towards each other, the parts attached to the surface of the moving mold 6 can be clamped and fixed on both sides. Next, the two third sliders 31 can be controlled to move to the right within their corresponding third grooves 30, using the two clamping plates 15 to pull the parts attached to the surface of the moving mold 6 to the right until the attached parts are pulled off the surface of the moving mold 6. This eliminates the need to stop the machine 1 and manually clean the parts, thus avoiding affecting the injection molding efficiency of the parts.

[0048] If the mold needs to be disassembled for repair or replaced, the two double-ended screws 27 can be rotated to push the second moving plate 14 upward until it abuts against the bottom of the moving mold 6 and the stationary mold 5. At this time, the two clamping plates 15 are located on both sides of the mold. First, control the two clamping plates 15 to move towards each other, so that the two clamping plates 15 abut tightly against the outer walls of the two sides of the mold, which has a clamping and fixing effect on the mold. Then, control the multiple rotating plates 18 to rotate downward away from the clamping plates 15, so that the rotating plates 18 on both sides of the two clamping plates 15 abut against the outer walls of the two sides of the moving mold 6 and the stationary mold 5. The electromagnets 20 inside the multiple connecting plates 19 can be energized to generate magnetism, so that the multiple connecting plates 19 can... The moving mold 6 and the stationary mold 5 are magnetically fixed to each other, improving the fixing effect of the mold. The bolts between the multiple telescopic columns 8 and the mounting base 7 are removed, and the multiple telescopic columns 8 are controlled to retract. Then, the stationary mold 5 is removed from the inner wall of one side of the housing 4, so that the moving mold 6 and the stationary mold 5 can be supported by the second moving plate 14 below. As the telescopic ends of the multiple first electric telescopic rods 23 are controlled to extend upward, the second moving plate 14 and the mold on its top are moved upward together to the top of the housing 4. With the double limiting fixation of the two clamping plates 15 and the electromagnets 20 inside the multiple connecting plates 19, the safety and stability of the mold moving upward to the top of the housing 4 are improved. There is no need for manual disassembly of the mold, which improves the efficiency of mold disassembly and maintenance.

[0049] When installing a new mold inside the housing 4, the second moving plate 14 can be moved to the top of the housing 4 by controlling it. The new mold is placed on the top of the second moving plate 14 and fixed by the double limiting of the two clamping plates 15 and multiple connecting plates 19. This makes the process of moving the mold into the housing 4 safer and more stable. It also makes it easier for subsequent workers to quickly install the moving mold 6 and the stationary mold 5 without the need for additional hoisting or other fixing equipment, further improving the applicability of the feeding mechanism.

[0050] If only the moving mold 6 or the stationary mold 5 needs to be disassembled and repaired, control the moving mold 6 and the stationary mold 5 to separate, and then control the two clamping plates 15 below to move to the bottom of the moving mold 6 or the stationary mold 5 that needs to be disassembled. After the two clamping plates 15 move upward a distance, the top of the two clamping plates 15 clamps and fixes the two sides of the moving mold 6 or the stationary mold 5. Then, with the second moving plate 14, the two clamping plates 15 move upward together, pushing the moving mold 6 and the stationary mold 5 that need to be disassembled to the top of the housing 4. After the workers remove them, the remaining moving mold 6 and the stationary mold 5 are exposed. The above steps of unfolding the multiple shielding curtains 21 can be repeated, so that the multiple shielding curtains 21 are unfolded, and with the help of the two third sliders 31, they move inside the third slide groove 30, driving the unfolded shielding curtains 21 to shield and protect the remaining moving mold 6 or the stationary mold 5, so as to prevent external debris from adhering to the surface of the moving mold 6 or the stationary mold 5 inside the housing 4, which would affect the subsequent use of the mold.

[0051] If disassembly and repair of the moving mold 6 or the stationary mold 5 are not required, and maintenance and repair are only performed directly inside the housing 4, refer to... Figure 5 As shown, after the multiple shielding curtains 21 are unfolded, multiple rotating plates 18 are then controlled to rotate downwards to a near-horizontal state. When the staff is inspecting and maintaining the mold above, any parts or lubricating oil that fall downwards can fall onto the top of the unfolded shielding curtains 21 and then onto the top of the second moving plate 14 along the lower end of the shielding curtains 21. This prevents parts from falling into the dead corners of the cavity 9 and affecting the subsequent normal operation of the internal components of the cavity 9. The lubricating oil that falls onto the top of the shielding curtains 21 can be guided to the top of the second moving plate 14. By controlling the two moving strips 17 to move back and forth on the top of the second moving plate 14, the lubricating oil that falls onto the top of the second moving plate 14 can be evenly spread on its surface, avoiding waste of the lubricating oil that drips downwards. This also facilitates the subsequent back and forth movement of the two moving strips 17 on the top of the second moving plate 14 and improves the smoothness of the movement of the two moving strips 17.
