Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of plastic molds, in particular to a synchronous linkage mechanism of multiple cores on a mold. Background Art
[0002] During the mold opening process, multiple cores within a plastic mold typically move independently. This structure offers a simple core-pulling mechanism and is less likely to damage the part. However, mold opening is relatively time-consuming, requiring all cores to be fully released from the part before the mold can be separated from the fixed and movable molds and ejected. This results in long production cycles and difficulty improving efficiency. Utility Model Content

[0008] The linkage part includes one or more synchronization parts arranged on the slider and extending horizontally toward the cavity. A second slideway is provided on the side wall of each synchronization part close to the cavity and extending obliquely toward the direction away from the cavity. A second core is slidably mounted on the second slideway. Each second core is provided with an inclined third slideway. Each third slideway can accommodate a guide rod.

[0023] like Figure 1-3 As shown, a synchronous linkage mechanism for multiple cores on a mold is provided on a plastic mold. The plastic mold includes a fixed platen and a movable platen 20. The fixed platen is embedded with a fixed mold core, and the movable platen 20 is embedded with a movable mold core 30. Both the fixed mold core and the movable mold core 30 are formed with a cavity that matches the plastic part; the synchronous linkage mechanism includes a driving member 40, a transmission member 50, and a linkage member 60. The transmission member 50 and the linkage member 60 are all transmission-connected to one or more independent cores. The driving member 40 can drive the transmission member 50 to drive the linkage member 60 to move synchronously, thereby synchronously driving multiple cores to approach or move away from the cavity; wherein:
[0024] The driving member 40 includes one or more push rods 41 arranged obliquely. The push rods 41 are arranged in parallel, one end of each push rod is provided on the fixed platen, and the other end of each push rod extends obliquely to the outside of the fixed platen and extends toward the movable platen 20 and away from the cavity.
[0025] The transmission member 50 includes a slider 51 that is slidably mounted on the movable platen 20 and disposed beside the movable mold core 30. The slider 51 is provided with one or more first slideways 52 that are adapted one-to-one with the push rods 41 and are inclined. A first core 70 is provided on the side wall of the slider 51 close to the cavity. When the mold is closed, the movable platen 20 moves toward the fixed platen, and each push rod 41 can slide on a first slideway 52 to push the slider 51 to slide on the movable platen 20 and drive the first core 70 thereon to approach the cavity. When the mold is opened, the movable platen 20 moves away from the fixed platen, and each push rod 41 can slide on a first slideway 52 to push the slider 51 to drive the first core 53 thereon away from the cavity.
[0026] The linkage part 60 includes one or more synchronization parts 61 provided on the slider 50 and extending horizontally toward the cavity. A second slide 63 is provided on the side wall of each synchronization part 61 close to the cavity and extending obliquely toward the direction away from the cavity. A second core 80 is slidably installed on the second slide 63. Each second core 80 is provided with an inclined third slide 81. Each third slide 81 can accommodate a guide rod 62. Each guide rod 62 is installed on the movable mold core 30 and is horizontally provided on the side of the cavity. Each guide rod 62 can slide on a third slide 81 to push a second core 80 to slide on a second slide 63 and away from or close to the cavity.
[0027] During mold closing, the movable mold drives the movable platen 20 and the movable mold core 30 to move synchronously toward the fixed platen. The inclined push rod 41 first contacts the slider 51 and slides within the inclined first slide 52, pushing the slider 51 to translate laterally on the movable platen 20 and approach the cavity, synchronously pushing the first core 70 and the synchronizer 61 to move laterally toward the cavity. The guide rod 62 on the movable mold core 30 pushes the second core 80 to slide on the second slide 63 to approach the cavity longitudinally, pushing the first core 70 and the second core 80 laterally into the cavity, and pushing the second core 80 longitudinally into the cavity. During mold opening, the movable platen 20 and the movable mold core 30 leave the fixed platen. The push rod 41 pushes the slider 51 to translate laterally away from the cavity, synchronously pulling the first core 70 and the second core 80 laterally away from the cavity. At the same time, the guide rod 62 on the movable mold core 30 pushes the second core 80 to slide on the inclined second slide 63, driving the second core 80 longitudinally away from the cavity.
[0028] The utility model provides a push rod 41 on the fixed template, a synchronizer 61 on the slider 51 on the movable template 20, and a second core 80 that can slide obliquely thereon on the synchronizer 61. During the mold closing and mold opening processes, the slider 51 can be pushed to move horizontally on the movable template 20, and the first core 70 can be driven away from the mold cavity, and the second core 80 can be driven away from the first core 70 and the mold cavity. This realizes the synchronous movement of multiple cores with different moving paths, shortens the overall movement time of the core in the mold, shortens the mold molding cycle, and improves the mold production efficiency.
[0029] Further, such as Figure 1 As shown, a horizontal fourth slideway 21 is provided on the movable template 20 , and the fourth slideway 21 and a plurality of guide rods 62 and synchronizers 61 all extend in the same direction.
[0030] It can be understood that the horizontal fourth slide 21 can guide the translation direction of the slider 51, and the horizontal guide rod 62 can cooperate with the inclined third slide 81 to push the second core 80 to slide on the inclined second slide 63, so that the second core 80 can move away from the movable mold core 30 and away from the cavity (plastic product) to avoid damaging the structural parts on the plastic product.
[0031] In this embodiment, if Figure 1-2 As shown, the lower template 20, the lower mold core 30, the slider 51 and the guide rod 63 are all placed horizontally, the first core 70 is a semicircular ring structure and is arranged horizontally, and the two second cores 80 are radially inclined and symmetrically arranged on the inner side of the first core 70; the first slide 52 is longitudinally arranged along the mold closing direction and extends obliquely in the direction away from the cavity, and the second slide 63 passes through the second core and extends obliquely in the same direction as the second core 80.
[0032] Further, such as Figure 4 As shown, each second slideway 63 is an I-shaped slideway.
[0033] It can be understood that the I-shaped sliding groove structure can prevent the second core 80 from being separated from the synchronizer 61 during the sliding process.
[0034] Further, such as Figure 5 As shown, each third slideway 81 is a waist-shaped slide groove running through the second core 80 .
[0035] In application, the third slideway 81 may also be configured as an arcuate groove or an inclined groove according to the actual structural characteristics of the plastic product, to ensure that the second core 80 does not damage the plastic product when it moves horizontally.
[0036] Further, such as Figure 2-3 As shown, the first core 70 is horizontally arranged on the side wall of the slider 50 close to the cavity, and is detachably fixedly connected to the slider 50 or integrally formed.
[0037] Further, such as Figure 1As shown, a plurality of pairs of one-to-one matching guide members 90 are provided on the movable plate 20 and the fixed plate.
[0038] It can be understood that the setting of the guide member 90 can further guide the movable mold plate 20 and the fixed mold plate, thereby ensuring that the movable mold core and the fixed mold core and the cavities thereon can be fully matched and engaged, ensuring molding accuracy.
[0039] The above does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
