Description

Technical Field

[0001] The present invention relates to the technical field of injection molding of air-conditioning plastic components, and specifically to an injection molding machine for air-conditioning plastic components. Background Art

[0002] An injection molding machine for air-conditioning plastic components is an injection molding device specifically used to process thermoplastic plastic raw materials into air-conditioning components. The plastic particles are heated to a molten state by a heating device, and then, under a certain pressure and speed, the molten plastic is injected into a pre-designed mold cavity. After cooling and solidifying, the mold is opened to take out the formed air-conditioning plastic components.

[0003] When the air-conditioning plastic components are cooled to sufficient hardness and strength, the mold clamping system of the injection molding machine opens the mold, and then the formed air-conditioning components are ejected from the mold cavity through an ejection device. After the taken-out components are inspected and trimmed, they can enter the next production process or be directly used as finished products. Then the mold will be closed again and enter the next injection molding cycle.

[0004] However, in actual production, defects such as burrs and bubbles may occur in the components after air-conditioning injection molding. Generally, such defects are caused by factors such as injection pressure, speed, mold sealing degree, and screw rotation speed. However, after checking one by one, it is found that product defects still exist in some cases. Later, through the experience of our company's experienced R & D personnel, it is found that this situation mainly occurs during the maintenance period. The main reason is that when the air-conditioning plastic components are normally fed, they are transported by the rotation of the injection screw. During injection, the injection screw stops rotating, and the injection nozzle pressurizes to push the injection. Since the motor of the injection screw is generally controlled manually for old machines and by sensors for new machines, it is found that when the operator forgets to stop the rotation of the injection screw or the sensor is damaged and insensitive, the injection screw does not stop and still rotates during injection.

[0005] In addition, when the plastic is fed, since the temperature in the injection screw cavity is very high, when pushing the injection, due to the pushing of the injection screw, even when there is no feeding, some plastic will still enter the conveying bin. And this part of the plastic just simply follows the injection screw forward, then melts at high temperature, and then retreats to the feed inlet. Over time, the feed inlet is blocked due to the solidification of the melted plastic at the feed inlet, making it difficult to feed.

[0006] At the same time, currently, since the feeding process is for plastic products, generally two schemes are adopted for the body to feed. For small components, after injection molding, they are directly pushed out and then fall by gravity. For large components, it is completed in cooperation with a multi-degree-of-freedom mechanical gripper. Here, it mainly refers to small air-conditioning components. Although they are plastic products, due to just being injection molded, each time they fall, there will still be products that are knocked, damaged, and deformed.

[0007] On this basis, the present invention provides an injection molding machine for air-conditioning plastic components to solve the above problems. Summary of the Invention

[0019] The present invention has the following technical effects.

[0020] 1. When the injection molding motor of the present invention drives in the pushing direction, it drives the injection molding screw connected to it through a structural connection to rotate. The injection molding screw can push the raw materials of the air conditioner component towards the direction of the fixed air conditioner component mold. At the same time, the rotating injection molding screw will drive the blocking and dispersing frame connected to it to rotate. The rotating blocking and dispersing frame breaks and mixes the component raw materials to ensure the quality of the subsequent injection molding raw materials. The blocking and dispersing frame also blocks the material transfer, increasing the residence time of the component raw materials. With the help of the heater, the raw materials are fully melted to ensure the state of the raw materials. When the injection molding push rod works, it can drive the injection molding screw, the conical block and the injection molding head to move. First, the conical block contacts the sealing sleeve to seal the injection molding space, and then the raw materials are pushed out to achieve injection molding. When the injection molding screw is pushed out, the matching block is disengaged from the matching card slot, and the connection structure does not limit the rotation of the matching block. Therefore, during the injection molding process, the injection molding screw does not rotate along with it, greatly reducing the situation that the injection molding screw rotates along with it during the injection molding due to improper operation or malfunction, reducing the influence of the injection molding process, and reducing the occurrence of defects in the air conditioner plastic component products.

[0021] 2. When the driving motor of the present invention works, in cooperation with the rotating wheel and the crawler, it can drive the adjusting shaft to rotate. The rotation of the adjusting shaft in different directions can achieve the purpose of only mixing and crushing without discharging materials or continuously discharging materials during the mixing and crushing process. At this time, it can be selected according to the state of the component raw materials, greatly improving the actual efficiency of the subsequent injection molding work. At the same time, when the adjusting shaft rotates, it can drive the connecting shaft cleaning brush to rotate along with it, and can clean the materials adhered to the surface of the cleaning plate turned into a horizontal state. When the push plate is pushed to move, with the transmission of the connecting arm and the hinge connection between the cleaning plate itself and the through hole, the cleaning plate is driven to rotate, which can scrape the inner wall of the through hole and can also block the bottom port of the material cylinder, reducing the situation of blockage and difficult feeding caused by too high temperature at the feeding port during the injection molding work.

[0022] 3. When the feeding push rod of the present invention works, it drives the moving air conditioner component mold and the moving seat to move. When the moving air conditioner component mold moves towards the direction of the fixed air conditioner component mold, the connection and cooperation between the moving air conditioner component mold and the fixed air conditioner component mold can be realized. At the same time, it can drive the adjusting frame fixedly installed on the moving seat to move. In cooperation with the inclined chute, it drives the rotating shaft and the buffer plate to rotate in the vertical direction. When the feeding push rod works and drives the moving air conditioner component mold away from the fixed air conditioner component mold, during the movement of the moving air conditioner component mold, the component is pushed out of the moving air conditioner component mold by means of the pushing rod. At the same time, during the movement, (through the above principle) the buffer plate is driven to rotate in the horizontal direction. After demolding, the component will fall onto the buffer plate in a horizontal state. When the fixed air conditioner component mold is connected to the moving air conditioner component mold, the buffer plate discharges materials vertically, and vice versa, the buffer plate receives materials horizontally, achieving the purpose of automatically buffering and discharging materials.

[0033] Regarding the foregoing and other technical contents, features and effects of the present invention, they will be clearly presented in the following detailed description of the embodiments in conjunction with the attached Figures 1 to 9 drawings. The contents mentioned in the following embodiments are all with reference to the drawings of the specification.

[0034] The following will describe the exemplary embodiments of the present invention with reference to the drawings.

[0035] The present invention relates to an injection molding machine for air conditioner plastic components, including an injection molding support base 1, an injection molding storage box 2, an injection molding outer shell 3, and an injection molding fixing frame 6. The injection molding outer shell 3 is fixedly installed on the top of the injection molding storage box 2. An injection molding motor 27 is fixedly installed inside the injection molding outer shell 3. The injection molding motor 27 is connected to a power supply and a controller. An injection molding frame 5 is fixedly installed inside the injection molding outer shell 3. The settings of the injection molding outer shell 3 and the injection molding frame 5 provide a reasonable installation space for promoting injection molding and feeding and mixing. One end of the output shaft of the injection molding motor 27 is fixedly installed with a grooved frame 17 placed inside the injection molding frame 5. An engaging groove 42 is formed inside the grooved frame 17. The engaging groove 42 is provided with an annular internal tooth. A connecting structure 44 is arranged inside the grooved frame 17. The connecting structure 44 can cooperate with an engaging block 43 to drive the rotation for work. An engaging block 43 is slidably connected inside the connecting structure 44. The outer side of the engaging block 43 is provided with an annular external tooth. The engaging groove 42 and the engaging block 43 can be matched. One end of the engaging block 43 is welded with a support rod 38. The surface of the support rod 38 is rotatably connected with a support sleeve 37. The support sleeve 37 is a structure formed by the cooperation of a sleeve and an extension plate. Specifically, an annular groove is formed inside the support sleeve 37. An annular block is fixed on the outer side of the support rod 38. The block can rotate in the groove. When the groove moves, it can drive the block to move together. An injection molding push rod 28 is arranged between the support sleeve 37 and the injection molding frame 5. The injection molding push rod 28 is externally connected to a controller and a driving power supply. The injection molding push rod 28 provides the driving force for injection molding. One end of the support rod 38 is welded with an injection molding screw 29. The injection molding screw 29 is a structure formed by the combination of a shaft with a gradually increasing diameter and screw blades. A plurality of blocking and dispersing frames 36 are fixedly installed on the surface of the injection molding screw 29. The blocking and dispersing frames 36 are arc-shaped. The blocking and dispersing frames 36 can block the material transportation to a certain extent. One end of the injection molding screw 29 is fixedly installed with a connecting rod 39. A conical block 41 is fixedly installed on the surface of the connecting rod 39. One end of the connecting rod 39 is fixedly installed with an injection molding head 31. An inner cavity 35 is formed inside the injection molding frame 5. The conical block 41 can push the material to assist injection molding. A sealing sleeve 40 is slidably installed inside the inner cavity 35. The sealing sleeve 40 is placed between the conical block 41 and the injection molding head 31. When the sealing sleeve 40 is attached to the conical block 41, it can seal the front injection space, reducing the occurrence of insufficient thrust or the extrusion of materials. The injection molding fixing frame 6 is fixedly installed between the injection molding support base 1 and the injection molding storage box 2. A fixing seat 7 is fixedly installed inside the injection molding fixing frame 6. A fixed air conditioner component mold 9 is fixedly installed on one side of the fixing seat 7. The fixed air conditioner component mold 9 can assist in the injection molding of air conditioner components. One end of the injection molding frame 5 communicates with one side of the fixed air conditioner component mold 9.

[0036] The connecting structure 44 includes an outer sleeve 441 fixedly installed inside the slotted frame 17. A gear 442 is provided inside the outer sleeve 441, and the shape of the gear 442 is a right trapezoid. A rotating wheel 447 is rotatably connected inside the outer sleeve 441. A plurality of circumferentially distributed return springs 446 are arranged inside the rotating wheel 447. The return springs 446 can provide continuous elastic force restriction to the limiting block 443, so as to ensure the state of the limiting block 443 during operation. One end of the return spring 446 is welded with a limiting slider 445, and a limiting block 443 is fixedly installed on one side of the limiting slider 445. One end of the limiting block 443 is an inclined surface. A mating block 43 that can cooperate with the mating slot 42 is slidably and rotatably connected inside the rotating wheel 447. A plurality of heaters 30 are installed inside the injection molding frame 5. The heaters 30 are electrically connected to an external controller and a driving power supply. The heaters 30 can melt the raw materials of the air-conditioning component. The number of heaters 30 is four. A limiting chute 444 is provided inside the rotating wheel 447, and the limiting slider 445 is slidably connected inside the limiting chute 444.

[0037] In this embodiment, during the feeding process, the mating block 43 is stuck inside the mating slot 42 as the initial state, and the connecting structure 44 is connected. At this time, the slotted frame 17 rotates to drive the outer sleeve 441 to rotate, and the outer sleeve 441 drives the gear 442 to rotate. When the gear 442 rotates, it compresses the limiting block 443 along the teeth and passes through.

[0038] When the injection molding motor 27 drives in the pushing direction, the mating slot 42 meshes with the mating block 43, thereby driving the mating block 43 to rotate, and driving the injection molding screw 29 connected to it through the structural connection to rotate accordingly. The injection molding screw 29 can push the raw materials of the air-conditioning component towards the direction of the air-conditioning component mold 9. At the same time, the rotating injection molding screw 29 will drive the blocking and dispersing frame 36 connected to it to rotate. The blocking and dispersing frame 36 can break and mix the component raw materials, and the blocking and dispersing frame 36 blocks the material transmission, so that the component plastic is fully melted.

[0039] When the injection molding push rod 28 works, it pushes the support sleeve 37 forward. The support sleeve 37 drives the support rod 38 to move forward. At this time, the mating block 43 stuck inside the mating slot 42 disengages from the mating slot 42, so as to stop the rotation of the injection molding screw 29.

[0040] When injection is performed, the matching block 43 disengages from the matching slot 42, stops driving the injection screw 29 to rotate, and when the injection screw 29 is pushed forward, the component raw material can also be injected from one side of the fixed air conditioning component mold 9 to realize the injection work. When the injection work is completed, the controller drives the injection motor 27 in the reverse direction, and drives the injection push rod 28 to drive the injection screw 29 away from the fixed air conditioning component mold 9, and drives the injection screw 29 to rotate the connecting structure 44 in the reverse direction. At this time, the slotted frame 17 rotates to drive the outer sleeve 441 to rotate, and the outer sleeve 441 drives the gear 442 to rotate. When the gear 442 rotates, the reverse gear pushes the limit block 443 The limiting block 443 rotates to drive the matching block 43 to rotate, thereby driving the injection screw 29 to rotate, until the matching block 43 is driven to fit into the matching slot 42, stopping the injection push rod 28 from working, and controlling the injection motor 27 to drive in the pushing direction to continue to assist in pushing the material, thereby achieving repeated injection molding. When pushing the injection molding work forward, in order to improve the injection molding efficiency and stability and avoid product defects, the injection molding screw 29 needs to remain stationary, otherwise the injection molding screw 29 needs to rotate to assist in mixing. Such a design can prevent the injection molding screw 29 from rotating due to operational errors or machine failures during the injection molding process, thereby affecting the product quality of the air conditioning components.

[0041] As an embodiment, a barrel 4 is fixedly installed on the injection molding shell 3 and the injection molding frame 5, the bottom end of the barrel 4 and the inner cavity 35 are connected to each other, a limiting sleeve 26 is fixedly installed inside the barrel 4, and the limiting sleeve 26 provides a support structure for the mounting frame and sleeve combination installed on the inner wall of the barrel 4, which can provide limiting support for the adjustment shaft 25, and the adjusting shaft 25 is rotatably connected inside the limiting sleeve 26, and a stirring frame 32 is fixedly installed on the surface of the adjustment shaft 25. The stirring frame 32 can break up and mix the materials inside the barrel 4, and can dry and preheat the component raw materials in combination with additional heating equipment. A connecting sleeve 33 is fixedly installed at the bottom of the stirring frame 32, and a material discharger is fixedly installed at the bottom of the connecting sleeve 33. The auger 34 and the rotation of the unloading auger 34 can push the air-conditioning raw materials into the inner cavity 35 in an orderly and controllable manner, thereby improving the efficiency of loading and injection molding. The barrel 4 is funnel-shaped as a whole, and a closable protective cover is provided on the top of the barrel 4. The loading can be manual, mechanical, vacuum loading, etc. according to actual needs. A drive motor 22 is fixedly installed on one side of the barrel 4. The drive motor 22 is electrically connected to an external controller and a drive power supply through a wire. The drive motor 22 cooperates with a rotating wheel 23 and a crawler track 24 to realize the driving work of the adjustment shaft 25. A rotating wheel 23 is provided on the top of the output shaft of the drive motor 22, and the surface of the rotating wheel 23 is transmission-connected with the crawler track 24, and the crawler track 24 is arranged on the surface of the adjustment shaft 25 through another rotating wheel 23.

[0042] In this embodiment, when feeding is required, the raw materials of the air-conditioning component are first added into the interior of the barrel 4, and the driving motor 22 is controlled to operate. In cooperation with the runner 23 and the crawler 24, the adjusting shaft 25 is driven to rotate. When the adjusting shaft 25 rotates in the direction of the auger blade of the feeding auger 34, the material can be conveyed into the interior cavity 35 while being scattered by the stirring frame 32. When driven in the reverse direction, only the stirring and scattering work can be achieved. In cooperation with an external heating device, the scattered raw materials can be assisted in preheating and drying treatment.

[0043] As an embodiment, through holes 53 are provided inside the injection molding frame 5. The through holes 53 are located below the limiting sleeve 26 and the feeding auger 34 inside it. The through holes 53 can assist in feeding. A cleaning plate 54 is hinged inside the through hole 53. The shape of the cleaning plate 54 can assist in scraping the inner wall of the through hole 53 to reduce the occurrence of material solidification and blockage. The cross-sections of both the through hole 53 and the cleaning plate 54 are square. The side length of the through hole 53 is equal to the diameter dimension of the outer diameter of the bottom of the barrel 4. The side length of the cleaning plate 54 is greater than the side length of the through hole 53, and the material of the cleaning plate 54 is heat-resistant and has a certain elasticity, or the lower end of the cleaning plate 54 is a telescopic structure with an internal spring, so that after the cleaning plate 54 rotates 90°, it can contact and press against the corresponding side of the through hole 53. A connecting arm 55 is hinged on the cleaning plate 54, and a push plate 56 is hinged on the connecting arm 55. The push plate 56 is fixedly installed on one side of the support sleeve 37. A connecting shaft cleaning brush 52 is fixedly installed at a position near the bottom end of the surface of the feeding auger 34.

[0044] In this embodiment, in the case of injection molding, since the injection molding push rod 28 pushes the support sleeve 37 forward, the push plate 56 is driven to move forward passively following the injection molding push rod 28. The push rod 56 pushes the connecting arm 55 to move. In cooperation with the hinge between the connecting arm 55 and the cleaning plate 54, and by means of the hinge between the cleaning plate 54 itself and the through hole 53, the cleaning plate 54 is driven to flip. When the cleaning plate 54 flips, its two sides contact the two sides of the through hole 53. Since the length of the cleaning plate 54 itself is slightly longer than that of the through hole 53, the cleaning plate 53 can contact the other side of the through hole 53 as it rotates and continue to rotate to clean the other side of the through hole 53. Since the cleaning plate 54 is heat-resistant and elastic or the lower end is a telescopic structure, it can press against the other side of the through hole 53 to clean it until the through hole 53 is completely closed. At this time, with the stop of the injection molding push rod 28, the cleaning plate 54 also stops. At this time, the cleaning plate 54 is just located at the lower end of the connecting shaft cleaning brush 52. At the same time, the driving motor of the adjusting shaft 25 is driven to rotate in the reverse direction. The reverse-rotating feeding auger 34 will drive the connecting shaft cleaning brush 52 to rotate. The rotating connecting shaft cleaning brush 52 can clean the surface of the cleaning plate 54, so as to achieve that when pushing the injection, the through hole 53 can be closed and the cleaning of the solidified material after melting at the feeding port can be realized.

[0045] As an embodiment, a blanking groove 15 is formed inside the injection molding support base 1. A blanking push rod 18 is fixedly installed on the injection molding support base 1. The blanking push rod 18 is electrically connected to an external controller and a driving power supply. One end of the output shaft of the blanking push rod 18 is fixedly installed with a moving seat 11. A moving air-conditioning component mold 10 is fixedly installed on one side of the moving seat 11. A space for cooling is formed inside the moving air-conditioning component mold 10. Material ports are provided in both the upper and lower parts of the moving air-conditioning component mold 10. By connecting the material ports and a circulating pump, cooling liquid can be injected from the bottom and pushed out from the upper part to achieve liquid circulation cooling work. The moving air-conditioning component mold 10 is matched with the fixed air-conditioning component mold 9. A fixing plate 19 is fixedly installed on the top of the injection molding support base 1. A connecting cylinder frame 48 is fixedly installed inside the fixing plate 19. The connecting cylinder frame 48 can limit and support the moving rod 49. The moving rod 49 is slidably connected inside the connecting cylinder frame 48. One end of the moving rod 49 is fixedly installed with a pushing rod 51 that is slidably connected inside the moving seat 11 and the moving air-conditioning component mold 10. The pushing rod 51 can push and blank the air-conditioning component. A buffer spring 50 is arranged between the moving seat 11 and the moving rod 49. The arrangement of the buffer spring 50 can buffer and support the movement of the pushing rod 51, reducing the problem that the fixed installation occupies a large space. If the position of the fixedly installed pushing rod 51 is inconvenient to adjust or even cannot be adjusted, it will affect the actual disassembly and assembly work of the moving air-conditioning component mold 10. A rotating shaft 46 is rotatably connected inside the blanking groove 15. A buffer plate 47 is fixedly installed on one side of the rotating shaft 46. An inclined sliding groove 45 is formed on the rotating shaft 46. The inclined sliding groove 45 is a curved sliding groove, and its opening angle is 90°. An adjusting frame 20 is slidably connected inside the inclined sliding groove 45. The adjusting frame 20 is fixedly connected to the bottom of the moving seat 11.

[0046] In this embodiment, when blanking is required, the controller controls the blanking push rod 18 to drive away from the fixed air-conditioning component mold 9, driving the moving air-conditioning component mold 10 and the moving seat 11 to move away from the fixed air-conditioning component mold 9. Initially, the moving air-conditioning component mold 10 and the moving seat 11 will drive the pushing rod 51 to move a certain distance. Until the moving rod 49 moves to the inner end of the connecting cylinder frame 48, the pushing rod 51 is blocked and cannot move. At this time, the moving air-conditioning component mold 10 continues to move, and the air-conditioning plastic component on the moving air-conditioning component mold 10 is pushed out by the pushing rod 51. At the same time, it will drive the adjustment frame 20 fixedly installed on the moving seat 11 to move. When the adjustment frame 20 moves, it cooperates with the inclined chute 45 to drive the rotating shaft 46 and the buffer plate 47 to rotate horizontally. When the component is pushed out, the buffer plate 47 is exactly in a horizontal state. At this time, the demolded component will first fall above the buffer plate 47. When injection molding needs to be carried out again, first drive the moving air-conditioning component mold 10 and the moving seat 11 to move closer to the fixed air-conditioning component mold 9 through the blanking push rod 18 until the moving air-conditioning component mold 10 is in full contact with the fixed air-conditioning component mold 9. At the same time, the moving seat 11 moving closer to the fixed air-conditioning component mold 9 will drive the adjustment frame 20 to move accordingly. The adjustment frame 20 cooperates with the inclined chute 45 to drive the rotating shaft 46 and the buffer plate 47 to rotate vertically. At this time, the component detaches from the buffer plate 47 and falls into the blanking chute 15, thus realizing the blanking work.

[0047] As an embodiment, a limiting rod 8 is welded to one side of the fixed plate 19. A connecting sleeve 21 is provided inside the moving seat 11. The moving seat 11 is slidably connected to the limiting rod 8 through the connecting sleeve 21. A protective shell 12 is fixedly installed on the injection molding support seat 1. A protective baffle 13 is slidably connected inside the protective shell 12. An observation window 16 is arranged on the surface of the protective baffle 13.

[0048] It should be noted that during the above operation process, during startup, stop, travel displacement, etc., it is realized by programming or the required corresponding sensors.

[0049] Working principle: S1. First, add the raw materials of the air-conditioning component into the barrel 4. Then, by controlling the driving motor 22 to work, cooperate with the rotating wheel 23 and the crawler 24 to drive the adjusting shaft 25 to rotate. The adjusting shaft 25 drives the limiting sleeve 26 and the blanking auger 34 to rotate. At this time, according to the state of the component raw materials (such as when the dryness does not meet the standard or the mixing degree is insufficient, select the driving direction that cannot feed the material to rotate, otherwise directly select the driving direction that can feed the material to rotate). Finally, inject the component raw materials into the inner cavity 35 of the injection molding frame 5.

[0050] S2. At the same time, the controller controls the material discharge push rod 18 to work, driving the moving seat 11 and the dynamic air conditioning component mold 10 to move forward. When the dynamic air conditioning component mold 10 is installed with the fixed air conditioning component mold 9, the moving seat 11 drives the adjustment frame 20 to move, and the adjustment frame 20 pushes the inclined slide 45, the rotating shaft 46 and the buffer plate 47 to drive the buffer plate 47 to rotate in the vertical direction. Then, the injection molding motor 27 can be controlled to rotate in the material pushing direction, driving the injection molding screw 29 to rotate accordingly, and continuously pushing the material in the direction of the fixed seat 7. At the same time, the heater 30 is controlled to work to heat, melt and mix the component raw materials inside the inner cavity 35. During the pushing process, the moving materials are broken up and blocked to a certain extent with the help of the blocking and breaking frame 36, so as to improve the mixing efficiency of the materials and prolong the time for the materials to stay and heat. After the pushing is completed, the injection molding push rod 28 can be controlled to work, driving the support sleeve 37, the injection molding screw 29 and the injection molding head 31 to move toward the fixed air conditioning component mold 9. During the movement, the matching block 43 disengages from the matching slot 42, and the matching connection structure 44 prevents the injection molding motor 27 from driving the injection molding screw 29 to rotate during the injection process. The conical block 41 contacts the sealing sleeve 40, closes the pushing space, and injects the materials into the fixed air conditioning component mold 9 for injection molding.

[0051] S3. After the injection molding is completed, the injection molding motor 27 can be controlled to drive and rotate in the opposite direction mentioned above, driving the injection molding screw 29 to rotate in the opposite direction. At the same time, the injection molding push rod 28 works in the opposite direction to drive the injection molding screw 29 to move in the direction of the injection molding shell 3. The matching block 43 is controlled to be inserted into the matching slot 42. At this time, the position of the injection head 31 is restored to prepare for the next injection molding. When the injection molding is completed for a period of time and demoulding is required, the unloading push rod 18 drives the moving seat 11 and the dynamic air-conditioning component mold 10 to drive away from the fixed air-conditioning component mold 9. At this time, the dynamic air-conditioning component mold 10 is away from the fixed air-conditioning component mold 9, and the push rod 51 is following As the moving seat 11 moves a certain distance and then is fixed, the dynamic air-conditioning component mold 10 and the moving seat 11 continue to move, and the push rod 51 is misaligned with the dynamic air-conditioning component mold 10 to eject the component. When the moving seat 11 moves in the direction away from the fixed air-conditioning component mold 9, the adjustment frame 20 cooperates with the inclined slide groove 45 to drive the rotating shaft 46 and the buffer plate 47 in the horizontal direction. When the component is detached, it will fall on the horizontal buffer plate 47 until the next injection molding work (proposed in S2 that during injection molding, the buffer plate 47 will be adjusted to a vertical state to realize the unloading work). Continue the above operation to repeatedly perform injection molding processing on the component.

[0052] The present invention has the following technical effects.

[0053] 1. When the injection molding motor of the present invention drives in the pushing direction, it drives the injection molding screw connected to it through a structural connection to rotate. The injection molding screw can push the raw materials of the air conditioner component towards the direction of the fixed air conditioner component mold. At the same time, the rotating injection molding screw will drive the blocking and dispersing frame connected to it to rotate. The rotating blocking and dispersing frame breaks and mixes the component raw materials to ensure the quality of the subsequent injection molding raw materials. The blocking and dispersing frame also blocks the material transfer, increasing the residence time of the component raw materials. With the help of the heater, the raw materials are fully melted, ensuring the state of the raw materials. The injection molding push rod works and can drive the injection molding screw, the conical block and the injection molding head to move. First, the conical block contacts and seals the sealing sleeve to seal the injection molding space, and then the raw materials are pushed out to achieve injection molding. When the injection molding screw is pushed out, the cooperation between the clamping block and the cooperation card slot is disengaged, and the connection structure does not limit the rotation of the cooperation clamping block. Therefore, during the injection molding process, the injection molding screw does not rotate, greatly reducing the situation where the injection molding screw rotates during the injection process due to improper operation or malfunction, reducing the impact of the injection molding process, and reducing the occurrence of defects in the air conditioner plastic component products.

[0054] 2. When the driving motor of the present invention works, in cooperation with the rotating wheel and the crawler, it can drive the adjusting shaft to rotate. The rotation of the adjusting shaft in different directions can achieve the purpose of only mixing and crushing without discharging materials or continuously discharging materials during the mixing and crushing process. At this time, it can be selected according to the state of the component raw materials, greatly improving the actual efficiency of the subsequent injection molding work. At the same time, when the adjusting shaft rotates, it can drive the connecting shaft cleaning brush to rotate, and can clean the materials adhered to the surface of the cleaning plate that is turned into a horizontal state. When the push plate is pushed to move, with the transmission of the connecting arm and the hinge connection between the cleaning plate itself and the through hole, the cleaning plate is driven to rotate, which can scrape and clean the inner wall of the through hole, and can also block the bottom port of the material cylinder, reducing the situation of blockage and difficult discharging caused by too high temperature at the feeding port during the injection molding work.

[0055] 3. When the feeding push rod of the present invention works, it drives the moving air conditioner component mold and the moving seat to move. When the moving air conditioner component mold moves towards the direction of the fixed air conditioner component mold, the connection and cooperation between the moving air conditioner component mold and the fixed air conditioner component mold can be achieved. At the same time, it can drive the adjusting frame fixedly installed on the moving seat to move. In cooperation with the inclined chute, it drives the rotating shaft and the buffer plate to rotate in the vertical direction. When the feeding push rod works and drives the moving air conditioner component mold away from the fixed air conditioner component mold, during the movement of the moving air conditioner component mold, with the help of the pushing rod, the component is pushed out from the inside of the moving air conditioner component mold. At the same time, during the movement, (through the above principle) the buffer plate is driven to rotate in the horizontal direction. The demolded component will fall onto the buffer plate in a horizontal state. When the fixed air conditioner component mold is connected to the moving air conditioner component mold, the buffer plate discharges materials vertically, and vice versa, the buffer plate receives materials horizontally, achieving the purpose of automatically buffering and discharging materials.
