Description

Technical Field

[0001] This invention relates to the field of air conditioner filter processing technology, specifically to an air conditioner filter forming mold and processing method. Background Technology

[0002] As people's demands for comfort in their living and working environments continue to increase, air conditioners are being used more and more widely. The function of an air conditioner is to cool or heat indoor air to regulate the air temperature. Its working process is as follows: air enters the air conditioner's internal unit through the air inlet, is cooled or heated, and then is discharged from the exhaust outlet.

[0003] To reduce damage to the indoor unit's internal components from dust or other impurities in the air, air conditioning filters are typically installed at the air inlet or airflow channel of the indoor unit to filter the air. Generally, for small air conditioners, such as household air conditioners, an air conditioning filter is installed at the air inlet of the blower; for large air conditioners, such as central air conditioning systems, multiple air conditioning filters are installed in the airflow channel. An air conditioning filter consists of a mesh forming a predetermined mesh size and a frame body for fixing the mesh. The frame body is fixed to the mesh body by injection molding.

[0004] The process of manufacturing air conditioner filters using traditional molds is as follows: First, a suitable mesh material is selected and cut to the desired size according to the required size of the air conditioner filter. Then, the cut mesh material is placed on the parting surface of the mold for the first and second molds to be closed. Molten plastic is injected into the side and reinforcing skeleton cavities through the injection port to form the air conditioner filter blank. After cooling, the mold is opened, and the air conditioner filter blank is ejected through the ejector pins in the lower mold. Finally, the excess mesh material beyond the predetermined size is trimmed to form the finished air conditioner filter. In a production line, after the air conditioner filter blank is ejected through the ejector pins in the lower mold, the next mesh material is placed on the parting surface of the mold, and the above operation is repeated.

[0005] As can be seen from the above production process, when using air conditioning filter molds for assembly line operation, it is necessary to manually install the mesh material of the specified size on the mold continuously. After each molding process is completed, the ejector pin needs to be controlled to eject the material, resulting in poor production efficiency. Furthermore, when the mesh material is processed, manual feeding can easily lead to poor flatness, causing wrinkles to easily form on the filter screen produced by the mold, making it difficult to control the quality.

[0006] In view of this, the present invention proposes an air conditioner filter forming mold and processing method. Summary of the Invention

[0007] This invention proposes an air conditioner filter molding die and processing method, which solves the problems in related technologies where manual installation of mesh material of a specified size is required on the die during the processing of air conditioner filter molds, resulting in poor production efficiency, and manual feeding of mesh material easily leads to poor flatness.

A limit groove is formed on the inner side of the shaft, and a limit post is slidably sleeved on the inner side of the limit groove. A return spring is connected between one end of the limit post and the limit groove, and a movable post is fixedly connected to the other end of the limit post. A star-shaped rod is fixed to the end of the movable post away from the limit post. A star-shaped groove for inserting the star-shaped rod is formed inside the socket.

[0018] Preferably, the conveying assembly includes two side frames, two rotating rollers are rotatably connected between the two side frames, a conveyor belt is driven between the two rotating rollers, the through groove is located above and to the right of the conveyor belt, and the side frames are welded and fixed to the support columns by clamping frames.

[0019] Preferably, the transmission assembly includes a motor fixedly mounted on a support block, a second gear fixedly attached to the end of the motor's output shaft, the second gear being rotatably connected to the support block and fixedly connected to the end of the shaft away from the baffle, a first gear being rotatably connected to the side frame, the first gear being fixedly connected to a roller located on one side thereof, and a chain being drivingly connected between the second gear and the first gear.

[0020] Preferably, the blowing and suction mechanism includes two sets of guide rope grooves symmetrically opened inside the fixed mold. Each set of guide rope grooves includes a traction rope, a horizontal rope groove, and a vertical rope groove. The horizontal rope groove and the vertical rope groove are connected to the vertical rope groove. A traction rope is slidably inserted inside the traction rope, the horizontal rope groove, and the vertical rope groove. One end of the traction rope is fixedly connected to a T-shaped rod, and the other end of the traction rope is fixed to a piston seat. An active cavity for placing the piston seat is opened inside the fixed mold. Several supporting components are provided between the bottom of the active cavity and the bottom end of the piston seat. Multiple communicating holes connected to the active cavity are opened on the outer wall of the fixed mold on the opposite side of the mold cavity.

[0021] The support component includes an outer cylinder fixedly connected to the bottom of the movable cavity and an inner rod fixedly connected to the bottom of the piston seat. The inner rod extends into the outer cylinder and is slidably connected thereto. A support spring is fixedly connected between the inner rod and the outer cylinder.

[0022] Preferably, the guide net assembly includes two uprights symmetrically fixed to the top of the U-shaped frame, a winding roller is rotatably connected between the two uprights, and a guide roller is rotatably connected inside the opening.

[0023] Preferably, the processing mold further includes several positioning posts fixedly connected to the outer wall of the fixed mold, and several positioning holes corresponding to the number of positioning posts are opened on the outer wall of the moving mold near the fixed mold.

[0024] A method for processing an air conditioner filter forming mold, using the aforementioned air conditioner filter forming mold, includes the following steps:

[0025] S1: The filter belt to be processed, which is required to make the air conditioner filter, is pre-wound onto the winding roller, and one end of the filter belt is pulled down onto the take-up roller for winding and fixing. At this time, the guide roller supports and drives the filter belt passing through the inner side of the opening, and the filter belt is in contact with the outer wall of the fixed mold near the moving mold.

[0026] S2: Intermittent motor start-stop. When the motor stops running, the electric hydraulic pump is started. The electric hydraulic pump pushes the moving mold closer to the fixed mold until the positioning pins are inserted into the positioning holes. At this time, the moving mold and the fixed mold are in contact with each other. The cutter cuts the filter screen belt that is in contact with the fixed mold. Then, the injection molding work is carried out.

[0027] S3: After injection molding is completed, the moving mold is pulled back by the electric hydraulic device, so that the moving mold and the fixed mold are far apart. At this time, the ejector pin is gradually pushed out from the mold cavity, and the mold attached to the mold cavity is ejected, so that the mold falls through the through groove onto the conveyor belt below the worktable.

[0028] S4: Next, start the motor. Under the combined action of the first gear, chain and second gear, the rotating roller can drive the conveyor belt to drive the transmission. The installation and removal parts can drive the winding roller to rotate. The transmission of the conveyor belt can transport the forming mold on it. The rotation of the winding roller can wind and wind the processed filter screen belt, so that the filter screen belt to be processed on the winding roller can be continuously and automatically released for the next processing work.

[0029] S5: As the moving mold approaches the fixed mold, it can drive the T-shaped rod to slide in the T-shaped groove. During this process, the T-shaped rod can lift the piston seat through the traction rope. The inner rod extends out from the inside of the outer cylinder and supports the spring tension. As the piston seat moves upward, the pressure in the movable cavity located on the lower side of the piston seat decreases, and suction is applied to the outside through the connecting hole. This provides a certain suction force to the filter belt located on the fixed mold side, improving the stability during operation. As the moving mold moves away from the fixed mold, the inner rod automatically moves downward and resets under the action of the support spring.

[0030] The working principle and beneficial effects of this invention are as follows:

[0031] (1) In this invention, several ejector rods are slidably sleeved inside the moving mold. The end of the ejector rod away from the fixed mold is fixedly connected to the inner wall of the U-shaped frame. Under the action of the ejector rod, the forming mold in the mold cavity can be automatically ejected during the separation of the moving mold and the fixed mold. A conveying component is provided on the support frame. The forming mold ejected by the ejector rod can be transported through the conveying component, realizing automatic material unloading and transportation work, which has good practical performance.

[0032] (2) In this invention, an annular cutter is fixed on the moving mold on the outer periphery of the mold cavity. Under the action of the annular cutter, the filter belt can be cut during the process of the moving mold fitting with the fixed mold. A guide assembly is provided on the U-shaped frame, which can wind and guide the filter belt to be processed. A winding assembly is provided on the inner side of the U-shaped frame, which can collect the processed filter belt. A transmission assembly is provided between the winding assembly and the conveying assembly, which can drive the winding assembly and the conveying assembly at the same time. When the winding roller on the winding assembly rotates, it can wind and wind the processed filter belt and tighten the filter belt to be processed, so that it fits against the outer wall of the fixed mold. This allows the filter belt to be processed on the winding roller to be continuously and automatically released for the next processing work. The degree of automation is high, and there is no need for manual installation of each filter screen, which greatly improves the work efficiency.

[0033] (3) In this invention, a blowing and suction mechanism is provided between the T-shaped rod and the fixed mold. Under the transmission cooperation with the T-shaped rod, the blowing and suction mechanism can blow and suction the filter belt located on the fixed mold side. In actual operation, as the moving mold moves closer to the fixed mold, it can drive the T-shaped rod to slide in the T-shaped groove. During this process, the T-shaped rod can lift the piston seat through the traction rope on the blowing and suction mechanism. During the upward movement of the piston seat, it can suck the outside through the connecting hole, thereby providing a certain suction force to the filter belt located on the fixed mold side, making the filter belt flatter during processing, improving the stability during operation, and improving the processing quality of the air conditioning filter element.

[0045] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. 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 of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0046] Please see Figure 1-9This invention provides a technical solution: an air conditioner filter forming mold and processing method, comprising: a support frame 1, a U-shaped frame 2 disposed above the support frame 1, a through-hole 201 opened at the top of the U-shaped frame 2, and a filter belt 4 extending to the inside of the through-hole 201. A processing mold 5 that cooperates with the filter belt 4 is disposed between the support frame 1 and the U-shaped frame 2. The processing mold 5 includes a moving mold 52 and a fixed mold 58 disposed parallel to each other inside the U-shaped frame 2. Two T-shaped rods 56 are fixed parallel to each other at the bottom end of the moving mold 52. The top ends of the T-shaped rods 56 slide against the bottom end of the fixed mold 58. A mold cavity 55 is opened on the outer wall of the moving mold 52 near the fixed mold 58. An electric hydraulic device 53 is disposed on the U-shaped frame 2 for adjusting the relative position of the moving mold 52 and the fixed mold 58. A ring-shaped cutter 59 is fixed on the moving mold 52 located on the outer periphery of the mold cavity 55. This cutter cuts the filter mesh 4 during the process of the moving mold 52 fitting with the fixed mold 58. Several ejector rods 54 are slidably sleeved inside the moving mold 52. The end of each ejector rod 54 away from the fixed mold 58 is fixedly connected to the inner wall of the U-shaped frame 2. These ejector rods are used to eject the forming mold in the mold cavity 55 during the separation of the moving mold 52 from the fixed mold 58. The processing mold 5 also includes several positioning pins 57 fixedly connected to the outer wall of the fixed mold 58. Several positioning holes 51, corresponding one-to-one with the number of positioning pins 57, are formed on the outer wall of the moving mold 52 on the side closest to the fixed mold 58.

[0047] Specifically, the support frame 1 includes a workbench 11, with support columns 12 fixed at the bottom of each of the four corners of the workbench 11. Two support columns 12 arranged along the length of the workbench 11 are jointly fixed to a base plate 13. A through groove 15 is formed at the top of the workbench 11, and two T-shaped grooves 14 are formed at the bottom of the workbench 11 on both sides of the through groove 15 for sliding T-shaped rods 56. A guide mesh assembly 3 is provided on the U-shaped frame 2 for winding and guiding the filter mesh belt 4 to be processed. The guide mesh assembly 3 includes two uprights 31 symmetrically fixed to the top of the U-shaped frame 2, with a winding roller 32 rotatably connected between the two uprights 31, and a guide roller 33 rotatably connected inside the opening 201.

[0048] During operation, the filter belt 4, required for making the air conditioner filter, is pre-wound onto the winding roller 32, and one end of the filter belt 4 is pulled down onto the take-up roller 83 for winding and fixing. At this time, the guide roller 33 supports and drives the filter belt 4 passing through the inner side of the through-hole 201, and the filter belt 4 is in contact with the outer wall of the fixed mold 58 near the moving mold 52. The electric hydraulic pump 53 is started, and the moving mold 52 is pushed closer to the fixed mold 58 until the positioning pins 57 are all inserted into the positioning holes 51. The moving mold 52 and the fixed mold 58 are in contact with each other. At this time, the cutter 59 cuts the filter belt 4 that is in contact with the fixed mold 58. After that, the injection molding process is carried out. After injection molding is completed, the moving mold 52 is pulled back by the electric hydraulic pump 53, so that the moving mold 52 and the fixed mold 58 are far apart. At this time, the ejector pin 54 gradually pushes out from the mold cavity 55 and ejects the mold attached to the mold cavity 55.

[0049] Furthermore, a blowing and suction mechanism 9 is provided between the T-shaped rod 56 and the fixed mold 58. The blowing and suction mechanism 9, in transmission cooperation with the T-shaped rod 56, can blow and suction the filter belt 4 located on one side of the fixed mold 58. The blowing and suction mechanism 9 includes two sets of guide rope grooves symmetrically opened inside the fixed mold 58. Each set of guide rope grooves includes a traction rope 91, a horizontal rope groove 92, and a vertical rope groove 93. The horizontal rope groove 92 and the vertical rope groove 94 are connected to the vertical rope groove 93. The traction rope 91 is slidably inserted inside the traction rope 91, the horizontal rope groove 92, and the vertical rope groove 93. One end of the traction rope 91 is fixedly connected to the T-shaped rod 56, and the other end of the traction rope 91 is fixed to a piston seat 95. An active cavity 97 for placing the piston seat 95 is opened inside the fixed mold 58. Several support components 96 are provided between the bottom of the active cavity 97 and the bottom end of the piston seat 95. Multiple connecting holes 98 connected to the active cavity 97 are opened on the outer wall of the fixed mold 58 opposite to the mold cavity 55. The support component 96 includes an outer cylinder 962 fixedly connected to the bottom of the movable cavity 97 and an inner rod 961 fixedly connected to the bottom of the piston seat 95. The inner rod 961 extends into the outer cylinder 962 and is slidably connected thereto. A support spring 963 is fixedly connected between the inner rod 961 and the outer cylinder 962. As the moving mold 52 moves closer to the fixed mold 58, it drives the T-shaped rod 56 to slide in the T-shaped groove 14. During this process, the T-shaped rod 56 can lift the piston seat 95 through the traction rope 91, and the inner rod 961 extends from the inside of the outer cylinder 962, supporting the spring 963 to stretch. As the piston seat 95 moves upward, the pressure in the movable cavity 97 located on the lower side of the piston seat 95 decreases, and suction is applied to the outside through the connecting hole 98, thereby providing a certain suction force to the filter belt 4 located on the side of the fixed mold 58 (the filter belt 4 has a certain density of pores, so the suction force on the filter belt 4 will not be too large), making the filter belt 4 flatter during processing and improving the stability during operation. As the moving mold 52 moves away from the fixed mold 58, the inner rod 961 automatically moves down and resets under the action of the support spring 963.

[0050] Furthermore, a conveying assembly 6 is provided on the support frame 1 for transporting the molding die ejected by the ejector rod 54. The conveying assembly 6 includes two side frames 63, with two rotating rollers 62 rotatably connected between them. A conveyor belt 61 is driven between the two rotating rollers 62. A through groove 15 is located above and to the right of the conveyor belt 61. The side frames 63 are welded and fixed to the support column 12 via clamping frames 64. As the ejector rod 54 gradually ejects from the mold cavity 55, it pushes the mold attached to the mold cavity 55, causing the mold to fall through the through groove 15 onto the conveyor belt 61 below the worktable 11.

[0051] It should be noted that a winding assembly 8 is provided inside the U-shaped frame 2 for collecting the processed filter belt 4. The winding assembly 8 includes two support blocks 84 fixedly connected to the base plate 13, two baffles 82 arranged in parallel between the two support blocks 84, a winding roller 83 fixedly connected between the two baffles 82, and a disassembly component 81 provided between the baffles 82 and the support blocks 84. The mounting / removing component 81 includes a socket 811 fixedly connected to the baffle 82 and a shaft 816 rotatably connected to the support block 84. A limiting groove 815 is formed inside the shaft 816, and a limiting post 818 is slidably fitted inside the limiting groove 815. A return spring 817 is connected between one end of the limiting post 818 and the limiting groove 815, and a movable post 814 is fixedly connected to the other end of the limiting post 818. A star-shaped rod 813 is fixed to the end of the movable post 814 away from the limiting post 818. A star-shaped groove 812 is formed inside the socket 811 for inserting the star-shaped rod 813. A transmission component 7 is provided between the winding assembly 8 and the conveying assembly 6 to drive both components. The transmission assembly 7 includes a motor 73 fixedly mounted on a support block 84. A second gear 74 is fixedly attached to the end of the output shaft of the motor 73. The second gear 74 is rotatably connected to the support block 84 and fixedly connected to the end of the shaft 816 away from the baffle 82. A first gear 71 is rotatably connected to the side frame 63. The first gear 71 is fixedly connected to a rotating roller 62 located on one side of it. A chain 72 is drivingly connected between the second gear 74 and the first gear 71. When the motor 73 is started, the rotating roller 62 can drive the conveyor belt 61 to drive the transmission under the combined action of the first gear 71, the chain 72, and the second gear 74. The mounting and dismounting component 81 can drive the winding roller 83 to rotate. The transmission of the conveyor belt 61 can transport the forming mold on it. The rotation of the winding roller 83 can wind and wind the processed filter screen belt 4, so that the filter screen belt 4 to be processed on the winding roller 32 can be continuously and automatically released for the next processing work.

[0052] Working principle and usage process: First, the filter belt 4 to be processed, which is required for making air conditioner filters, is pre-wound onto the winding roller 32, and one end of the filter belt 4 is pulled down onto the take-up roller 83 for winding and fixing. At this time, the guide roller 33 supports and drives the filter belt 4 passing through the inner side of the through-hole 201, and the filter belt 4 is in contact with the outer wall of the fixed mold 58 near the moving mold 52. Then, the motor 73 is started and stopped intermittently. When the motor 73 stops running, the electro-hydraulic pump 53 is started, and the moving mold 52 is pushed by the electro-hydraulic pump 53 to move it closer to the fixed mold 58 until the positioning pins 57 are all inserted into the positioning holes 51. The moving mold 52 and the fixed mold 58 are in contact with each other. At this time, the cutter 59 cuts the filter belt 4 that is in contact with the fixed mold 58. Then, the injection molding process is carried out. After injection molding is completed, the moving mold 52 is pulled back by the electro-hydraulic pump 53, causing the moving mold 52 and the fixed mold 58 to move away from each other. At this time, the ejector rod 54 gradually pushes out from the mold cavity 55, ejecting the mold attached to the mold cavity 55, so that the mold falls through the through groove 15 onto the conveyor belt 61 below the worktable 11. Then, the motor 73 is started. Under the combined action of the first gear 71, the chain 72 and the second gear 74, the rotating roller 62 can drive the conveyor belt 61 to drive the transmission. The mounting and dismounting component 81 can drive the winding roller 83 to rotate. The transmission of the conveyor belt 61 can transport the molding mold on it. The rotation of the winding roller 83 can wind and wind the processed filter screen belt 4, so that the filter screen belt 4 to be processed on the winding roller 32 can be continuously and automatically released for the next processing work.

[0053] It is worth noting that as the moving mold 52 moves closer to the fixed mold 58, it drives the T-shaped rod 56 to slide in the T-shaped groove 14. During this process, the T-shaped rod 56 can lift the piston seat 95 through the traction rope 91, and the inner rod 961 extends from inside the outer cylinder 962, supporting the spring 963 to stretch. As the piston seat 95 moves upward, the pressure in the movable cavity 97 located below the piston seat 95 decreases, and suction is applied to the outside through the connecting hole 98. This provides a certain suction force to the filter belt 4 located on one side of the fixed mold 58, making it lay more evenly on the outer wall of the fixed mold 58, improving stability during operation, and ensuring the quality of the finished air conditioning filter. As the moving mold 52 moves away from the fixed mold 58, the inner rod 961 automatically moves downward and resets under the action of the support spring 963.

[0054] After the work is completed, the two movable columns 814 are moved away from each other, so that the limiting column 818 retracts into the limiting groove 815, and the star rod 813 is pulled out from the star groove 812. At this time, the two baffles 82 and the winding roller 83 between them can be easily removed, so as to facilitate the processing of the collected processed filter belt 4.

[0055] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

10. A method for processing an air conditioner filter forming mold, using an air conditioner filter forming mold as described in claim 9, characterized in that, Includes the following steps: S1: The filter belt (4) to be processed for making the air conditioner filter is pre-wound onto the winding roller (32), and one end of the filter belt (4) is pulled down onto the take-up roller (83) for winding and fixing. At this time, the guide roller (33) supports and drives the filter belt (4) passing through the inside of the through-hole (201), and the filter belt (4) is in contact with the outer wall of the fixed mold (58) near the moving mold (52). S2: Intermittent start and stop of motor (73). When the motor (73) stops running, start the electric hydraulic pump (53). The electric hydraulic pump (53) pushes the moving mold (52) closer to the fixed mold (58) until the positioning pins (57) are all inserted into the positioning holes (51). The moving mold (52) and the fixed mold (58) are in contact with each other. At this time, the cutter (59) cuts the filter belt (4) that is in contact with the fixed mold (58). Then, the injection molding work is carried out. S3: After injection molding is completed, the moving mold (52) is pulled back by the electric hydraulic press (53) so that the moving mold (52) and the fixed mold (58) move away from each other. At this time, the ejector pin (54) is gradually ejected from the mold cavity (55) to eject the mold attached to the mold cavity (55) so that the mold falls through the through groove (15) onto the conveyor belt (61) below the worktable (11). S4: Next, start the motor (73). Under the combined action of the first gear (71), chain (72) and second gear (74), the rotating roller (62) can drive the conveyor belt (61) to drive the transmission. The mounting and dismounting parts (81) can drive the winding roller (83) to rotate. The transmission of the conveyor belt (61) can transport the forming mold on it. The rotation of the winding roller (83) can wind and wind the processed filter screen belt (4), so that the filter screen belt (4) to be processed on the winding roller (32) can be continuously and automatically released for the next processing work. S5: As the moving mold (52) moves closer to the fixed mold (58), it can drive the T-shaped rod (56) to slide in the T-shaped groove (14). During this process, the T-shaped rod (56) can lift the piston seat (95) through the traction rope (91). The inner rod (961) extends out from the inside of the outer cylinder (962) and the support spring (963) is stretched. As the piston seat (95) moves upward, the pressure in the active cavity (97) located on the lower side of the piston seat (95) decreases. It draws out the outside through the connecting hole (98), thereby providing a certain suction force to the filter belt (4) located on the side of the fixed mold (58) and improving the stability during operation. As the moving mold (52) moves away from the fixed mold (58), the inner rod (961) automatically moves down and resets under the action of the support spring (963).
