Description

Technical Field

[0001] This utility model belongs to the field of injection mold technology, and in particular relates to a convenient installation injection mold with guiding function. Background Technology

[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. Its advantages include high production speed and efficiency, automated operation, a wide variety of designs and shapes (from simple to complex), and sizes ranging from large to small. It also produces precise dimensions, facilitates product updates, and can create complex shapes. Injection molding is suitable for mass production and molding processes involving complex shapes. When using injection molding, injection molds are required to achieve the desired product shape.

[0003] Currently, most injection molds automatically demold after the molded product cools down, and then the mold is removed. However, since it is impossible to guarantee that the molded product has completely cooled down, the product is easily damaged when it is removed from the mold, thus reducing the yield of the injection mold. Therefore, a convenient injection mold with a guiding function is provided. Utility Model Content

The top blocks are evenly distributed on the outer surface of the rotating disks, and the top blocks can exert a squeezing effect on the movable plate.

[0008] As a further description of the above technical solution:

[0009] A positioning rod is rotatably mounted on the inner wall of the movable plate. The positioning rod is located at the center of the movable plate. Support plates are fixedly mounted on both ends of the positioning rod. The lower surface of the support plate is fixedly connected to the upper surface of the movable mold. The positioning rod and the support plate cooperate to limit the movement of the movable plate.

[0010] As a further description of the above technical solution:

[0011] A striking block and a support spring are fixedly installed on the lower surface of the movable plate. The striking block and the support spring are located at both ends of the movable plate. One end of the support spring is fixedly connected to the upper surface of the moving mold. A protrusion is fixedly installed on the upper surface of the movable plate. The upper surface of the protrusion is in contact with the outer surface of the rotating disk. The protrusion is used to increase the tilt angle of the movable plate. The support spring plays a role in resetting the movable plate. The striking block is used to strike the moving mold, causing the moving mold to vibrate.

[0012] As a further description of the above technical solution:

[0013] The guide assembly includes a fixed base, on the upper surface of which a cylinder is fixedly mounted. The output end of the cylinder extends to the lower surface of the fixed base, and a guide rod is fixedly mounted on the lower surface of the fixed base.

[0030] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] In specific implementation, such as Figures 1-5As shown, this utility model provides a technical solution: a convenient injection mold with guiding function, including a stationary mold 1, the stationary mold 1 having a first liquid cooling pipe 5 inside, a positioning hole on the upper surface of the stationary mold 1, a through hole inside the stationary mold 1, and an injection port on the lower surface of the stationary mold 1; a moving mold 2, the moving mold 2 having a guide hole 8 inside, a second liquid cooling pipe 6 inside the moving mold 2, and a positioning block 7 fixedly installed on the lower surface of the moving mold 2, the positioning block 7 being compatible with the positioning hole on the stationary mold 1; a guiding component 3, the guiding component 3 being disposed on the side wall of the stationary mold 1, used to guide the movement direction of the moving mold 2; and a loosening component 4, the loosening component 4 being disposed on the upper surface of the moving mold 2, causing the moving mold 2 to vibrate during mold parting; wherein, the loosening component 4 includes a transmission gear 41 and a movable plate 46, a rotating rod 43 being fixedly installed on the inner wall of the transmission gear 41, and both ends of the rotating rod 43 extending to the outer surface of the transmission gear 41. In the movable mold 2, a positioning plate 42 is rotatably mounted on the outer surface of the rotating rod 43. The lower surface of the positioning plate 42 is fixedly connected to the upper surface of the movable mold 2. Rotating disks 44 are fixedly mounted at both ends of the rotating rod 43. A plurality of top blocks 45 are fixedly mounted on the outer surface of the rotating disks 44, and the top blocks 45 are evenly distributed on the outer surface of the rotating disks 44. A positioning rod 47 is rotatably mounted on the inner wall of the movable plate 46, and the positioning rod 47 is located at the center of the movable plate 46. Support plates 48 are fixedly installed at both ends. The lower surface of the support plates 48 is fixedly connected to the upper surface of the moving mold 2. A striking block 49 and a support spring 410 are fixedly installed on the lower surface of the movable plate 46. The striking block 49 and the support spring 410 are located at both ends of the movable plate 46. One end of the support spring 410 is fixedly connected to the upper surface of the moving mold 2. A protrusion 411 is fixedly installed on the upper surface of the movable plate 46. The upper surface of the protrusion 411 is in contact with the outer surface of the rotating disk 44.

[0032] After the product cools and solidifies, cylinder 32 drives the moving mold 2 to move upward under the limit of guide rod 33. At this time, the moving mold 2 will pull the cooled product out of the stationary mold 1. When the moving mold 2 moves, it will drive the transmission gear 41 to move in the guide groove 35 through the positioning plate 42. At this time, under the action of the fixed rack 36, the transmission gear 41 rotates on the inner wall of the positioning plate 42 through the rotating rod 43, thereby driving the rotating disk 44 to rotate synchronously. As the rotating disk 44 rotates, it will drive the top block 45 to rotate synchronously. When the top block 45 and the protrusion 411 are pressed together, one end of the movable plate 46 will press against the protrusion. Under the action of block 411, it will be pressed down. After the top block 45 and the protrusion 411 are misaligned, under the action of the support spring 410, one end of the movable plate 46 will drive the protrusion 411 to reset. As the top block 45 rotates, the movable plate 46 swings back and forth between the support plates 48 under the action of the positioning rod 47. At this time, the movable plate 46 drives the other end of the striking block 49 to continuously strike the upper surface of the moving mold 2, thereby causing the moving mold 2 to vibrate, which in turn causes the product to loosen from the moving mold 2, and then the product is removed. This realizes the function of the injection mold itself being able to vibrate, thereby reducing the demolding difficulty of the injection mold.

[0033] like Figures 2-5 As shown, the guide assembly 3 includes a fixed base 31, on the upper surface of which a cylinder 32 is fixedly mounted. The output end of the cylinder 32 extends to the lower surface of the fixed base 31. A guide rod 33 is fixedly mounted on the lower surface of the fixed base 31. One end of the guide rod 33 passes through the guide hole 8 of the moving mold 2 and the through hole of the stationary mold 1, and extends to the lower surface of the stationary mold 1. The inner wall of the guide hole 8 of the moving mold 2 is slidably connected to the guide rod 33. The inner wall of the through hole of the stationary mold 1 is fixedly connected to the outer surface of the guide rod 33. One end of the cylinder 32 is fixedly connected to the upper surface of the moving mold 2. A support column 34 is fixedly mounted on the side wall of the fixed base 31. A guide groove 35 is provided on the side wall of the support column 34. A fixed rack 36 is fixedly mounted on the inner wall of the guide groove 35. A portion of the transmission gear 41 is located inside the guide groove 35. The transmission gear 41 meshes with the fixed rack 36.

[0034] The cylinder 32 drives the moving mold 2 to move towards the stationary mold 1. At this time, the moving mold 2 slides down the outer surface of the guide rod 33 through the guide hole 8. After the lower surface of the moving mold 2 is tightly attached to the upper surface of the stationary mold 1, the movement of the moving mold 2 stops. At this time, the positioning block 7 on the moving mold 2 is inserted into the positioning hole on the stationary mold 1, so that the moving mold 2 and the stationary mold 1 are in the correct position. Then, the plastic solution is injected into the stationary mold 1 through the injection port. After the injection is completed, coolant is injected into the first liquid cooling pipe 5 and the second liquid cooling pipe 6. With the flow of coolant, the heat in the mold is absorbed, which plays a guiding role in the movement of the moving mold 2 in the injection mold, ensuring the fit and accuracy of the moving mold 2 and the stationary mold 1.

[0035] Working principle: Cylinder 32 drives the moving mold 2 towards the stationary mold 1. At this time, the moving mold 2 slides down the outer surface of the guide rod 33 through the guide hole 8. After the lower surface of the moving mold 2 is tightly attached to the upper surface of the stationary mold 1, the movement of the moving mold 2 stops. At this time, the positioning block 7 on the moving mold 2 is inserted into the positioning hole on the stationary mold 1, so that the moving mold 2 and the stationary mold 1 are in the correct position. Then, the plastic solution is injected into the stationary mold 1 through the injection port. After the injection is completed, coolant is injected into the first liquid cooling pipe 5 and the second liquid cooling pipe 6. With the flow of coolant, the heat in the mold is absorbed. After the product cools and forms, cylinder 32 drives the moving mold 2 to move upward under the limit of the guide rod 33. At this time, the moving mold 2 will pull the cooled product out of the stationary mold 1. When the moving mold 2 moves, it will drive the transmission gear 41 through the positioning plate 42 in the guide groove 35. The internal movement occurs when the transmission gear 41 rotates on the inner wall of the positioning plate 42 via the rotating rod 43 under the action of the fixed rack 36, thereby driving the rotating disk 44 to rotate synchronously. As the rotating disk 44 rotates, it will drive the top block 45 to rotate synchronously. When the top block 45 and the protrusion 411 are pressed together, one end of the movable plate 46 will be pressed down under the action of the protrusion 411. After the top block 45 and the protrusion 411 are misaligned, under the action of the support spring 410, one end of the movable plate 46 will drive the protrusion 411 to reset. As the top block 45 rotates, the movable plate 46 swings back and forth between the support plates 48 under the action of the positioning rod 47. At this time, the movable plate 46 drives the other end of the striking block 49 to continuously strike the upper surface of the moving mold 2, thereby causing the moving mold 2 to vibrate, which in turn loosens the product from the moving mold 2, and then the product is removed.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
