Description

Technical Field

[0001] This utility model relates to mold making devices, and more particularly to a mold making device with a vibration mechanism. Background Technology

[0002] An existing mold assembly for molding threaded products includes three molds and a threaded core. The threaded core is rotatably connected to the third mold and passes through the second mold. The first mold, the second mold, and the threaded core cooperate to form a mold cavity for molding the threaded product. The mold parting process after molding is as follows: first, the first and second molds separate; then, the second and third molds separate while the threaded core rotates to remove the thread; finally, an ejector pin pushes the product out. In actual production, there is a situation where the product's tail thread gets caught on the threaded core and cannot be detached, thus reducing production efficiency and posing a risk of mold damage. Utility Model Content

[0004] The technical solution adopted by this utility model to solve its technical problem is: a mold device with a vibration mechanism, including a first mold 1, a second mold 2, a third mold 3 and a core 4. The first mold 1, the second mold 2 and the third mold 3 are arranged along a first direction. The core 4 is rotatably connected to the third mold 3 and passes through the second mold 2. The first mold 1, the second mold 2 and the core 4 cooperate to form a mold cavity 8 for molding a threaded product 7. It also includes a drive mechanism and a vibration mechanism 5. The vibration mechanism 5 includes a swing seat 51, a transmission rod 52 and a striking seat 53. The drive mechanism is installed on the third mold 3. The swing seat 51 is oscillatingly connected to the third mold 3 and can strike the striking seat 53 by oscillation. The striking seat 53 is fixed to the second mold 2. The transmission rod 52 is operatively connected to the drive mechanism and the swing seat 51. The drive mechanism drives the swing seat 51 to oscillate. The oscillating swing seat 51 strikes the striking seat 53 to vibrate the second mold 2.

[0005] The drive mechanism includes a slider 61 that is slidably connected to the third mold 3 in a first direction. The slider 61 is fixed with an ejector pin 62 that passes through the second mold 2 to eject the product 7.

[0006] The swing base 51 has a triangular structure and has a pivot part 511 and a driving part 512 and a striking part 513 located on both sides of the pivot part 511. The pivot part 511 can be rotatably connected to the third mold 3. One end of the transmission rod 52 is fixed to the slider 61, and the other end can abut against the driving part 512. The striking part 513 corresponds to the striking seat 53 so that when the swing base 51 swings to the correct position, it can strike the striking seat 53.

[0007] The third mold 3 is fixed with a limiting seat 31, which corresponds to the swing seat 51 to limit the maximum angle of the swing seat 51 in the opposite direction.

Detailed Implementation

[0028] Please refer to Figures 1 to 2 The product 7 formed by the mold device in this specific embodiment includes a ring seat 71 and a protruding ring 72 extending outward from one end of the ring seat 71. The inner hole of the ring seat 71 is provided with an internal thread, and the outer side of the ring seat 71 is provided with ribs. The bottom is formed with... Figure 1 , 2 This example is taken as an illustration, but it is not limited to this and can also be used to form internal or external threads of other structures.

[0029] Please refer to Figures 3 to 12 A mold device with a vibration mechanism includes a first mold 1, a second mold 2, a third mold 3, a threaded core 4, a drive mechanism, and a vibration mechanism 5. The first mold 1, second mold 2, and third mold 3 are arranged vertically. The threaded core 4 is rotatably connected to the third mold 3 and passes upward through the second mold 2. The first mold 1, second mold 2, and threaded core 4 cooperate to form a mold cavity 8 for molding a threaded product 7. The upper part of the threaded core 4 can form the internal thread of the product 7. The vibration mechanism 5 includes a swing base 51, a transmission rod 52, and a striking seat 53. The drive mechanism is mounted on the third mold 3. The swing base 51 is oscillatingly connected to the third mold 3 and can strike the striking seat 53 by oscillation. The striking seat 53 is fixed to the second mold 2. The transmission rod 52 drives the drive mechanism and the swing base 51, and the drive mechanism drives the swing base 51 to oscillate. The oscillating swing base 51 strikes the striking seat 53, causing the second mold 2 to vibrate, forcing individual products 7 that have not automatically detached to automatically detach under the action of vibration.

[0030] The drive mechanism includes a slider 61 that can slide along a first direction and is connected to the third mold 3. The slider 61 is fixed with an ejector pin 62, which passes through the second mold 2 to eject the product 7. The ejector pin and the vibration mechanism share the slider. On the one hand, this reduces costs and simplifies the structure. On the other hand, the vibration of the second mold and the ejection of the product are carried out simultaneously, which improves the product removal efficiency.

[0031] In this specific embodiment: the swing base 51 has a triangular structure and has a pivot part 511 and a driving part 512 and a striking part 513 located on both sides of the pivot part 511. The pivot part 511 is at the bottom, and the driving part 512 and the striking part 513 are at the top. The pivot part 511 can be rotatably connected to the third mold 3, such as by a pin. One end of the transmission rod 52 is fixed to the slider 61, and the other end can push against the driving part 512 from bottom to top, driving the swing base 51 to swing clockwise around the pivot part 511. The striking part 513 corresponds to the struck seat 53 so that when the swing base 51 swings clockwise downwards to the position, it can strike the struck seat 53 from top to bottom. The triangular structure facilitates assembly and weight increase. The arrangement of the pivot part at the bottom allows the weight of the swing base to strike the struck seat 53, improving the striking effect and vibration effect. The third mold 3 is fixed with a limiting seat 31. An outward-facing arc portion 514 is formed between the pivot portion 511 and the driving portion 512. The limiting seat 31 is located below the center of the arc portion 514 to restrict the swing seat 51 from swinging counterclockwise downwards under its own weight, thus limiting the maximum counterclockwise swing angle, reducing the swing stroke of the swing seat, and reducing the energy required to drive the swing seat to swing. The end of the arc portion 514 forms the aforementioned driving portion 512, facilitating the transmission rod 52 to abut against the driving portion 512 from bottom to top. If necessary, the limiting seat 31 may include a pin fixed to the third mold and a roller sleeved around the pin. The striking portion 513 extends outwards as a striking arm structure, enhancing the striking effect. The struck seat 53 is a lug fixed to the second mold 2 by a pin. In this specific embodiment: the transmission rod 52 and the swing seat 51 are located on the side wall of the third mold 3, and the struck seat 53 is located on the side wall of the second mold 2, facilitating assembly and resulting in a compact structure.

[0032] In this specific embodiment: the mold device is described using the molding of two products 7 as an example. It is provided with two mold cavities 8 and two tooth cores 4. Each tooth core 4 is fixed with a gear 32. The two gears 32 are the same and mesh with each other so that they can rotate synchronously, thereby driving the two tooth cores 4 to rotate synchronously and realize synchronous tooth unwinding.

[0033] Please refer to Figure 3 and Figure 4 The mold assembly is in the closed state; please refer to [link / reference]. Figure 5 and Figure 6 The first mold 1 and the second mold 2 are separated (first mold separation); please refer to [link / reference]. Figure 7 and Figure 8The second mold 2 and the third mold 3 separate, and simultaneously, the two gears 32 are driven by another driving mechanism (such as a motor) to rotate synchronously to remove the teeth (second mold parting); please refer to Figure 9 and Figure 10 The slider 61 slides upward (e.g., driven by a hydraulic or pneumatic mechanism), which drives the transmission rod 52 to move upward, so as to push against the driving part 512 of the swing seat 51 from bottom to top, causing the swing seat 51 to swing clockwise around the pivot part 511, so that the striking part 513 of the swing seat 51 strikes the striking seat 53, thereby driving the second mold 2 to vibrate. At the same time, the slider 61 also drives the ejector pin 62 to move upward, so as to eject the product 7 and make the product 7 fall off.

[0034] The above description is only a preferred embodiment of the present utility model, and therefore cannot be used to limit the scope of the present utility model. All equivalent changes and modifications made in accordance with the scope of the present utility model patent and the contents of the specification should still fall within the scope of the present utility model.
