Description

Technical Field

[0001] This utility model relates to the field of injection mold processing technology, specifically a positioning device for processing refrigerator injection molds. Background Technology

[0002] Injection molds for refrigerator drawers are the core equipment for producing refrigerator drawers. Their design, processing, material selection, cost, and maintenance directly affect the quality and production cost of the drawers. Some existing injection molds use positioning rods and positioning sleeves to guide the moving mold during use, making it more stable when moving.

[0003] The existing positioning rods require regular lubrication by staff to reduce the friction between the positioning rod and the positioning sleeve. However, manual lubrication is not only inconvenient but also prone to being forgotten, which increases the friction when the positioning rod and the positioning sleeve come into contact. Over time, this will reduce the guiding effect of the positioning rod and affect the accuracy of mold closing.

[0004] Meanwhile, after long-term use, some existing positioning rods will accumulate a lot of dust and other foreign matter on their surface. If they are not cleaned in time, the dust and other foreign matter can easily enter the interior of the positioning sleeve, thus affecting the accuracy of the positioning rod's position. Moreover, a lot of dust will also increase the friction between the positioning rod and the positioning sleeve, reducing the applicability of the positioning rod. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5As shown, a positioning device for refrigerator injection mold processing includes a fixed mold 1 and a movable mold 2 on one side of the fixed mold 1. With the cooperation of the fixed mold 1 and the movable mold 2, injection molding can be performed after mold closing to produce refrigerator drawers. Positioning rods 3 are fixedly connected to the surface of the movable mold 2. Several positioning rods 3 are present, and their surfaces are slidably connected to the inner wall of the fixed mold 1. This allows the movable mold 2 to move more stably through the cooperation of the positioning rods 3, preventing instability and positional displacement that could affect the normal use of the fixed mold 1 and the movable mold 2. A storage groove 4 is formed on the surface of the fixed mold 1, and the interior of the storage groove 4 is used to store lubricating grease. The inner cavity of the storage groove 4... An oil injection mechanism 6 is installed. Under the action of the oil injection mechanism 6, after the positioning rod 3 moves into the interior of the fixed mold 1, the grease inside the receiving groove 4 is squeezed onto the surface of the positioning rod 3, thereby reducing the friction between the inner wall of the fixed mold 1 and the positioning rod 3, thus improving the service life of the positioning rod 3 and making the positioning rod 3 more accurate during guidance. Two one-way valves 5 are installed in the inner cavity of the receiving groove 4. Under this action, the grease will not return to the interior of the receiving groove 4 after entering the interior of the fixed mold 1, thus avoiding the grease returning to the interior of the receiving groove 4 and affecting the lubrication effect on the positioning rod 3. A connecting groove 13 is opened in the inner cavity of the receiving groove 4, and the other side of the connecting groove 13 is connected to the receiving groove 4 below. The components are interconnected, allowing for simultaneous addition of grease to both storage slots 4 when adding it to the inside of the storage slot 4, which is convenient. The inner wall of the fixed mold 1 has an installation slot 7, and a power mechanism 8 is installed within the cavity of the installation slot 7. The power mechanism 8 works in conjunction with the positioning rod 3. A bevel gear ring 9 is provided on the surface of the power mechanism 8. As the positioning rod 3 enters the cavity of the fixed mold 1, the power mechanism 8 drives the bevel gear ring 9 to rotate, facilitating its subsequent use. A cleaning brush 10 is fixedly connected to one side of the bevel gear ring 9, and the surface of the cleaning brush 10 slides against the surface of the positioning rod 3. This allows for cleaning during the rotation of the bevel gear ring 9. The brush 10 cleans the surface of the positioning rod 3, preventing foreign objects from entering the mold 1. This reduces the likelihood of foreign objects adhering to the surface of the positioning rod 3 and entering the mold 1 cavity, thus affecting subsequent use and effectively improving the applicability of the device. The inner cavity of the mounting groove 7 is provided with a guide groove 12, and a guide ring 11 is rotatably connected to the inner cavity of the guide groove 12. The inner wall of the guide ring 11 is fixedly connected to the surface of the cleaning brush 10. Under this action, when the cleaning brush 10 rotates, it can be guided by the cooperation of the guide ring 11 and the guide groove 12, so that the cleaning brush 10 can be more stable when rotating, avoiding instability that would affect the cleaning effect on the positioning rod 3.

[0024] The oil injection mechanism 6 includes an oil collection bladder 61 fixed in the inner cavity of the fixed mold 1. One side of the oil collection bladder 61 is connected to the receiving groove 4. The inner cavity of the fixed mold 1 is provided with an oil outlet groove 62, which is connected to the oil collection bladder 61. An oil spray nozzle 63 is fixedly connected to the inner wall of the oil outlet groove 62. There are several oil spray nozzles 63. The other side of the one-way valve 5 works in conjunction with the oil outlet groove 62. Under this action, when the oil collection bladder 61 is not squeezed, the lubricating grease inside the receiving groove 4 can be drawn into the oil collection bladder 61 through the cooperation of the one-way valve 5 on one side. When it is squeezed, the lubricating grease is discharged from the oil spray nozzle 63 after passing through the oil outlet groove 62, thereby lubricating the surface of the positioning rod 3. This reduces the friction between the inner wall of the fixed mold 1 and the positioning rod 3, thereby improving the accuracy of the position when the fixed mold 1 and the moving mold 2 are closed.

[0025] The power mechanism 8 includes a bevel gear 81 that rotates within the mounting groove 7. A rotating roller 82 is fixedly connected to the bottom of the bevel gear 81. The surface of the bevel gear 81 meshes with the surface of the bevel ring 9. A connecting groove 83 is provided on the surface of the positioning rod 3. The inner wall of the connecting groove 83 is movably connected to the surface of the rotating roller 82. Under this action, the bevel gear 81 can drive the bevel ring 9 to rotate under the action of the friction force of the rotating roller 82 when the positioning rod 3 moves. This allows the cleaning brush 10 to rotate and clean the surface of the positioning rod 3, which is not only more convenient but also effectively improves the cleanliness of the positioning rod 3.

[0026] It is worth noting that the technical features such as the fixed mold 1, the moving mold 2, and the oil collection bladder 61 proposed in this technical solution should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be selected using conventional methods in this field. This technical solution will not elaborate further.

[0027] Working principle: First, when the moving mold 2 drives the positioning rod 3 to move, the rotating roller 82 can be rotated through the connection groove 83, thereby enabling the bevel gear 81 to drive the bevel gear ring 9 to rotate. This allows the cleaning brush 10 to clean the surface of the positioning rod 3, effectively reducing foreign matter on the surface of the positioning rod 3 and preventing excessive foreign matter from affecting the accuracy of the positioning rod 3's position. When the positioning rod 3 presses against the oil collection bladder 61, the oil collection bladder 61 cooperates with the two one-way valves 5, and the grease inside it enters the oil outlet groove 62 and is discharged from the oil spray head 63, thereby lubricating the surface of the positioning rod 3 and reducing the friction between the positioning rod 3 and the inner wall of the fixed mold 1. This not only improves the positioning effect of the positioning rod 3 but also extends its service life. Subsequently, injection molding is performed. After injection molding is completed, when the positioning rod 3 no longer presses against the oil collection bladder 61, with the cooperation of the two one-way valves 5, the oil collection bladder 61 will draw the grease inside the collection groove 4 into the oil collection bladder 61, thus facilitating subsequent use.
