Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically a precision mold with precise positioning function. Background Technology

[0002] Injection molds refer to the process where plastic is heated and melted inside the heated barrel of an injection molding machine, pushed by a screw or plunger, and enters the mold cavity through a nozzle and the mold's gating system, where the plastic hardens and solidifies.

[0003] According to a published injection mold partition (publication number: CN218857578U), the above application facilitates precise positioning and adjustment of the mold cavity size through the cooperation between the lower mold body and the adjustment mechanism, thereby enabling it to be used for injection molding of products of different sizes. This avoids the increased usage costs caused by changing different molds and thus improves the practicality of this utility model.

[0004] However, in actual use, although the above-mentioned equipment can adjust the size of the mold cavity, the cured plastic product is prone to sticking to the partition plate, which leads to the problem of inconvenience in subsequent material placement and positioning. In view of this, we propose a precision mold with accurate positioning function. Utility Model Content

[0005] The purpose of this invention is to provide a precision mold with accurate positioning function to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a precision mold with accurate positioning function, including a mold chamber, a threaded rod threadedly connected to the outer wall of the mold chamber, a baffle rotatably mounted at the end of the threaded rod, an anti-loosening and rubbing assembly provided on the outer wall of the baffle, the anti-loosening and rubbing assembly including an elastic telescopic post, the elastic telescopic post being fixedly connected to the outer wall of the baffle, an insert plate being fixedly connected to the end of the elastic telescopic post, a slot being opened on the outer wall of the mold chamber, a tough plate being fixedly connected to the outer wall of the baffle, and an upper fixing arc block being fixedly connected to the outer wall of the tough plate;

[0007] A swing plate is fixedly connected to the outer wall of a tough plate, and a striking ball is fixedly connected to the end of the swing plate. A lower fixed arc block is fixedly connected to the outer wall of the mold chamber.

[0008] Preferably, the number of upper fixed arc blocks is several, and the several upper fixed arc blocks are arranged in a linear array on the outer wall of the tough plate, so that when the several upper fixed arc blocks are displaced, they can rub against the lower fixed arc blocks, and then the plastic products attached to the outer wall of the baffle can be knocked off through vibration.

[0009] Preferably, the number of the toughening plates is two sets, and the two sets of toughening plates are arranged on both sides mirror images of the center plane of the baffle.

[0010] Preferably, the center line of the baffle and the center line of the threaded rod are on the same straight line, so that the baffle can be smoothly moved when the threaded rod is rotated.

[0011] Preferably, the outer wall of the baffle is provided with a release assembly, the release assembly includes a fixing plate, the fixing plate is fixedly connected to the outer wall of the baffle, the inner wall of the baffle is slidably connected to a sliding block, the outer wall of the sliding block is fixedly connected to a transmission rod, the outer wall of the transmission rod is fixedly connected to a sliding head, the outer wall of the transmission rod is fixedly connected to a top contact, and the outer wall of the mold cavity is provided with a guide groove.

[0012] Preferably, the outer wall of the sliding head is slidably connected to the inner wall of the guide groove, and the guide groove is wavy, so that the sliding head can move smoothly on the inner wall of the guide groove.

[0013] Preferably, the centerline of the top contact and the centerline of the fixed plate are both in the same plane, so that the top contact can periodically strike the outer wall of the fixed plate when it is moving up and down.

[0014] Compared with the prior art, this utility model provides a precision mold with accurate positioning function, which has the following beneficial effects:

[0015] 1. This precision mold with accurate positioning function, when it is necessary to adjust the size of the positioning mold chamber and the material feeding, after pulling up the insert plate to disengage it from the slot, the threaded rod can be rotated to drive the baffle forward, thereby adjusting the size of the positioning mold chamber and the material feeding. After rotating the threaded rod to drive the baffle forward for positioning, the insert plate can be lowered to enter the slot for further positioning, thus allowing the baffle to be better positioned. When the baffle is displaced, the flexible plate will be displaced simultaneously, so that several upper fixed arc blocks can rub against the lower fixed arc blocks when they are displaced, and the plastic products attached to the outer wall of the baffle can be knocked off through vibration. When the flexible plate is displaced, it will further drive the swing plate to swing and deform, so that the striking ball can periodically strike the baffle, and finally, even when the double-layer positioning is released, the plastic products attached to the baffle can be knocked off.

[0016] 2. This precision mold with accurate positioning function, when the rotating threaded rod drives the baffle to move, simultaneously causes the sliding head to move smoothly on the inner wall of the guide groove. This allows the top contact to periodically strike the outer wall of the fixed plate when the transmission rod moves up and down. By striking different directions, the plastic products attached to the outer wall of the baffle can be better knocked off. Furthermore, the vibration allows the insert plate to penetrate deeper into the bottom of the slot, further improving the positioning effect and ultimately enhancing the overall practicality.

[0023] like Figures 1-5 As shown, this utility model provides a technical solution: a precision mold with precise positioning function, including a mold chamber 1, a threaded rod 2 threadedly connected to the outer wall of the mold chamber 1, a baffle 3 rotatably installed at the end of the threaded rod 2, an anti-loosening and rubbing component 4 provided on the outer wall of the baffle 3, the anti-loosening and rubbing component 4 including an elastic telescopic post 401, the elastic telescopic post 401 fixedly connected to the outer wall of the baffle 3, an insert plate 402 fixedly connected to the end of the elastic telescopic post 401, a slot 403 opened on the outer wall of the mold chamber 1, a tough plate 404 fixedly connected to the outer wall of the baffle 3, and an upper fixing arc block 405 fixedly connected to the outer wall of the tough plate 404.

[0024] Furthermore, the swing plate 406 is fixedly connected to the outer wall of the tough plate 404, and the end of the swing plate 406 is fixedly connected to the striking ball 407. The outer wall of the mold chamber 1 is fixedly connected to the lower fixed arc block 408.

[0025] In this embodiment of the utility model, there are several upper fixed arc blocks 405, and these upper fixed arc blocks 405 are arranged in a linear array on the outer wall of the tough plate 404, so that when the upper fixed arc blocks 405 are displaced, they can rub against the lower fixed arc blocks 408, and then the plastic products attached to the outer wall of the baffle 3 can be knocked off through vibration. There are two sets of tough plates 404, and the two sets of tough plates 404 are mirror images of the center plane of the baffle 3 on both sides. The center line of the baffle 3 and the center line of the threaded rod 2 are on the same straight line, so that the baffle 3 can be smoothly moved when the threaded rod 2 is rotated.

[0026] Furthermore, the outer wall of the baffle 3 is provided with a release component 5, which includes a fixed plate 502. The fixed plate 502 is fixedly connected to the outer wall of the baffle 3. The inner wall of the baffle 3 is slidably connected with a sliding block 503. The outer wall of the sliding block 503 is fixedly connected with a transmission rod 504. The outer wall of the transmission rod 504 is fixedly connected with a sliding head 505. The outer wall of the transmission rod 504 is fixedly connected with a top contact 506. The outer wall of the mold chamber 1 is provided with a guide groove 501. The outer wall of the sliding head 505 is slidably connected to the inner wall of the guide groove 501. The guide groove 501 is wavy, so that the sliding head 505 can move smoothly on the inner wall of the guide groove 501. The center line of the top contact 506 and the center line of the fixed plate 502 are in the same plane, so that the top contact 506 can periodically hit the outer wall of the fixed plate 502 when it moves up and down.

[0027] In this invention, during daily use, molten plastic can be added to the mold chamber 1 to create the desired product. When it is necessary to adjust the size of the positioning mold chamber 1 and the material feeding, after pulling up the insert plate 402 so that the insert plate 402 disengages from the slot 403, the threaded rod 2 can be rotated to move the baffle 3 forward, thereby adjusting the size of the positioning mold chamber 1 and the material feeding. After rotating the threaded rod 2 to move the baffle 3 forward for positioning, the insert plate 402 can be lowered so that the insert plate 402 enters the slot 403 to achieve a further positioning effect, thereby making the baffle 3... It can be better positioned, and when the baffle 3 is displaced, it will simultaneously drive the flexible plate 404 to displace, so that when several upper fixed arc blocks 405 are displaced, they can rub against the lower fixed arc block 408, and then the plastic products attached to the outer wall of the baffle 3 can be knocked off through vibration. When the flexible plate 404 is displaced, it will further drive the swing plate 406 to swing and deform, so that the striking ball 407 can periodically strike the baffle 3, and finally the plastic products attached to the baffle 3 can be knocked off even after the double-layer positioning is released.

[0028] When the rotating threaded rod 2 drives the baffle 3 to move, the sliding head 505 will move smoothly on the inner wall of the guide groove 501. As a result, when the transmission rod 504 moves up and down, the top contact 506 can periodically hit the outer wall of the fixed plate 502. By hitting different directions, the plastic products attached to the outer wall of the baffle 3 can be better knocked off. Furthermore, the vibration allows the insert plate 402 to penetrate deeper into the bottom of the slot 403, further improving the positioning effect and ultimately enhancing the overall practicality.

[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
