Description

Technical Field

[0001] The utility model relates to a cutting mechanism for injection ports of plastic products of an automobile radiator water chamber, belonging to the field of automobile part production. Background Technique

[0002] The automobile water chamber is an important part of the automobile radiator. The water chambers are arranged at the upper and lower parts of the radiator core body, used for buffering the cooling water flowing into the core body, and conveying the cooled cooling water to the engine to continue absorbing heat. When the automobile water chamber is produced, it is generally injection molded. Since the injection molded parts will form a sprue at the injection port, it is necessary to remove the sprue after the water chamber injection molded parts are formed. The traditional sprue removal operation generally relies on manual labor, which is inefficient and increases the workload of workers. Therefore, a cutting mechanism is needed to remove the sprue of the water chamber.

[0003] In the prior art, some cutting mechanisms will transport the injection molded water chambers through a conveyor. After the water chamber moves for a period of time, the cutter will move towards the water chamber located below it under the action of the corresponding driving device, so as to remove the sprue on the side of the water chamber. However, the side of the water chamber to be removed of the sprue is prone to deviate from directly below the cutter during the transportation process, resulting in the side of the water chamber to be removed of the sprue being difficult to completely fit with the cutting surface, thus making the cutting effect of the sprue poor. Summary of the Utility Model

[0005] To achieve the above purpose, the utility model is realized by the following technical solutions: A cutting mechanism for injection ports of plastic products of an automobile radiator water chamber, including a base, a limiting component is arranged inside the base, a conveyor is fixedly connected above the limiting component at the top of the base, a cutting table is fixedly connected on one side of the conveyor at the top of the base, a waste box is slidably connected inside the cutting table, a positioning component is arranged on one side of the waste box inside the cutting table, and a cutting component is arranged outside the cutting table at the top of the base.

[0006] Furthermore, the limiting component includes a guiding groove opened at the top of the base, a bidirectional threaded rod is rotatably connected to the inner wall of the guiding groove, one end of the bidirectional threaded rod extends out of the base and is fixedly connected with a limiting motor, and two limiting pieces are threadedly connected to the surface of the bidirectional threaded rod.

The locking member is slidably connected to the positioning plate. A locking spring is sleeved on the surface of the locking member, and both between the locking spring and the support plate and between the locking spring and the locking member are fixedly connected. On one side of the locking member on the inner wall of the cutting table, a second sliding rod is fixedly connected. An unlocking member is slidably connected to the surface of the second sliding rod. A second return spring is sleeved on the surface of the second sliding rod, and both between the second return spring and the second sliding rod and between the second return spring and the unlocking member are fixedly connected.

[0008] Further, the cutting component includes a containing groove opened at the top end of the base. A lead screw is rotatably connected to the inner wall of the containing groove. One end of the lead screw extends out of the base and is fixedly connected to an adjusting motor. A support frame is threadedly connected to the surface of the lead screw.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please refer to Figure 1 , Figure 2 and Figure 3 , the present utility model provides a technical solution: an injection port cutting mechanism for an automobile radiator water chamber plastic product, including a base 1, a limiting component 2 is arranged inside the base 1, a conveyor 3 is fixedly connected above the limiting component 2 at the top end of the base 1, a cutting table 4 is fixedly connected on one side of the conveyor 3 at the top end of the base 1, a waste box 5 is slidably connected inside the cutting table 4, a positioning component 6 is arranged on one side of the waste box 5 inside the cutting table 4, and a cutting component 7 is arranged outside the cutting table 4 at the top end of the base 1.

[0022] By means of the limiting motor 23, the bidirectional threaded rod 22 and the guide groove 21, the two limiters 24 can be driven to move towards each other, so as to limit water chambers of different sizes, thus effectively improving the cutting effect;

[0023] By means of the adjusting motor 73, the lead screw 72 and the placing groove 71, the driving support frame 74 can be driven to move back and forth along the surface of the lead screw 72, so as to adjust the position of the cutter 78 above the cutting table 4 according to the length of the stock head, thus further improving the cutting effect. When one side of the stock head to be cut of the water chamber contacts the positioning plate 62, the water chamber will stop moving. During this process, the fixing frame 76 will contact the positioning plate 62, so as to prevent the water chamber from deviating from the cutter 78 during transportation, which is beneficial to improving the cutting effect. At this time, the cylinder 75, the cutter 78 and the cutting motor 77 will cut the stock head. The locking part 65 can lock the positioning plate 62, so as to prevent the positioning plate 62 from hindering the movement of the water chamber after cutting. With the cooperation of the first slide bar 61, the first return spring 63, the unlocking part 68, the second slide bar 67 and the second return spring 69, the positioning plate 62 and the locking part 65 will be reset after the water chamber completely moves away from the locking part 65, so as to perform the positioning process on the remaining water chambers. By the above steps, the water chamber is prevented from deviating from the cutter 78 during transportation, effectively improving the cutting effect.

[0024] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4, the present utility model provides a technical solution: The limiting component 2 includes a guiding groove 21 opened at the top end of the base 1. The inner wall of the guiding groove 21 is rotatably connected with a bidirectional threaded rod 22. One end of the bidirectional threaded rod 22 extends out of the base 1 and is fixedly connected with a limiting motor 23. Two limiting members 24 are threadedly connected to the surface of the bidirectional threaded rod 22. By means of the limiting motor 23, the bidirectional threaded rod 22 and the guiding groove 21, the two limiting members 24 are driven to move towards each other, so as to limit water chambers of different sizes, thereby effectively improving the cutting effect.

[0025] The in-place component 6 includes a first sliding rod 61 fixedly connected to the inner wall of the cutting table 4. The surface of the first sliding rod 61 is slidably connected with an in-place plate 62. A first return spring 63 is sleeved on the surface of the first sliding rod 61. The first return spring 63 is fixedly connected between the in-place plate 62 and the first sliding rod 61. A support plate 64 is fixedly connected to the inner wall of the cutting table 4 on one side of the first sliding rod 61. A locking member 65 is slidably connected inside the support plate 64. The locking member 65 is slidably connected with the in-place plate 62. A locking spring 66 is sleeved on the surface of the locking member 65. The locking spring 66 is fixedly connected between the support plate 64 and the locking member 65. A second sliding rod 67 is fixedly connected to the inner wall of the cutting table 4 on one side of the locking member 65. The surface of the second sliding rod 67 is slidably connected with an unlocking member 68. A second return spring 69 is sleeved on the surface of the second sliding rod 67. The second return spring 69 is fixedly connected between the second sliding rod 67 and the unlocking member 68. When one side of the water chamber to be cut contacts the in-place plate 62, the water chamber will stop moving. During the cutting process, the fixing frame 76 will contact the in-place plate 62, thereby preventing the water chamber from deviating from the cutter 78 during transportation, which is beneficial to improving the cutting effect. The locking member 65 can cooperate to lock the in-place plate 62, thereby preventing the in-place plate 62 from hindering the movement of the water chamber after the cutting is completed. With the cooperation of the first sliding rod 61, the first return spring 63, the unlocking member 68, the second sliding rod 67 and the second return spring 69, the in-place plate 62 and the locking member 65 will be reset after the water chamber completely moves away from the locking member 65, so as to perform in-place processing on the remaining water chambers. By the above steps, the water chamber is prevented from deviating from the cutter 78 during transportation, effectively improving the cutting effect.

[0026] The cutting component 7 includes a containing groove 71 formed at the top end of the base 1. The inner wall of the containing groove 71 is rotatably connected with a lead screw 72. One end of the lead screw 72 extends out of the base 1 and is fixedly connected with an adjusting motor 73. A support frame 74 is threadedly connected to the surface of the lead screw 72. The top end of the support frame 74 is fixedly connected with a cylinder 75. The telescopic end of the cylinder 75 extends out of the support frame 74 and is fixedly connected with a fixing frame 76. One side of the fixing frame 76 is fixedly connected with a cutting motor 77. The output end of the cutting motor 77 is fixedly connected with a cutter 78. The adjusting motor 73, the lead screw 72 and the containing groove 71 drive the support frame 74 to move back and forth along the surface of the lead screw 72, so that the position of the cutter 78 above the cutting table 4 can be adjusted according to the length of the material head, thereby further improving the cutting effect. The cylinder 75, the cutter 78 and the cutting motor 77 are used to cut the material head.

[0027] The top surface of the cutting table 4 is flush with the top surface of the conveyor 3, and the top surface of the waste box 5 is flush with the top surface of the cutting table 4. The top surface of the cutting table 4 being flush with the top surface of the conveyor 3 avoids the existence of convex or concave parts during the transportation of the water chamber. The top surface of the waste box 5 being flush with the top surface of the cutting table 4 prevents the waste box 5 from hindering the movement of the water chamber, thus ensuring the normal transportation of the water chamber.

[0028] A grinding sheet 8 is fixedly connected inside the cutter 78, and the side surface of the grinding sheet 8 is flush with the side surface of the cutter 78. By setting the grinding sheet 8, the cutting part can be ground while cutting, which not only helps to improve the cutting quality, but also greatly improves the cutting efficiency. The side surface of the grinding sheet 8 being flush with the side surface of the cutter 78 avoids the grinding sheet 8 hindering the operation of the cutter 78 during cutting.

[0029] Two abutting rods 9 are fixedly connected to both sides of the fixing frame 76, and the height of the abutting rods 9 is greater than the radius of the cutter 78. By setting the abutting rods 9 with a height greater than the radius of the cutter 78, it is prevented that the cutter 78 directly contacts the in-place plate 62, which is beneficial to extending the service life of the cutter 78 and the in-place plate 62.

[0030] Specific implementation method: Before the mechanism runs, start the limit motor 23 to drive the bidirectional threaded rod 22 to rotate. Due to the limitation of the guide groove 21, the two limit pieces 24 will move towards each other along the surface of the bidirectional threaded rod 22, so as to limit water chambers of different sizes, thereby effectively improving the cutting effect. Then start the adjusting motor 73 to drive the lead screw 72 to rotate. Due to the limitation of the containing groove 71, the support frame 74 will move back and forth along the surface of the lead screw 72, so that the position of the cutter 78 above the cutting table 4 can be adjusted according to the length of the material head, thereby further improving the cutting effect;

[0031] The conveyor 3 will convey the water chamber transported to the mechanism. When the side of the water chamber to be cut off the stock head contacts the positioning plate 62, the water chamber will stop moving. At this time, the air cylinder 75 will be activated and drive the cutter 78 to move towards the water chamber directly below it. During this process, the fixed frame 76 will contact the positioning plate 62 and push the positioning plate 62 to slide downward along the surface of the first slide bar 61 and compress the first return spring 63. The cutting motor 77 will drive the cutter 78 to rotate, and then the stock head of the water chamber can be cut off, thus preventing the water chamber from deviating from the cutter 78 during transportation, which is beneficial to improving the cutting effect. After cutting off the stock head, the air cylinder 75 will drive the cutter 78 to return to its original position. Since the locking part 65 will be inserted into the locking hole opened on the surface of the positioning plate 62 under the action of the locking spring 66 after the positioning plate 62 moves a certain distance, the positioning plate 62 will no longer hinder the movement of the water chamber. At this time, the water chamber will continue to move under the action of the conveyor 3. When the water chamber moves to one side of the unlocking part 68, it will squeeze the unlocking part 68 to make it slide downward along the second slide bar 67 and compress the second return spring 69, and then squeeze the locking part 65 to make it away from the positioning plate 62 and make the locking spring 66 contract. The positioning plate 62 will return to its original position under the action of the first return spring 63. After the water chamber completely moves away from the locking part 65, the top of the positioning plate 62 will extend out of the cutting table 4, and the locking part 65 will also extend out of the cutting table 4 under the action of the second return spring 69, so as to perform the positioning process on the remaining water chambers.

[0032] In addition, it should be understood that although this specification is described according to the embodiments, not each embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
