[0002] When products are manufactured through injection molds, in order to save space, a one-to-two slider motion structure is usually used. The movement of one slider drives the movement of two sliders, which can save mold space and make demolding operation simpler and more convenient.

[0003] For example, Chinese utility model patent CN222309624U discloses a large slider with two downward inclined core-pulling mechanism for injection molds of car headlight bases, belonging to the field of automotive parts. The core-pulling assembly includes a large slider, a hydraulic cylinder at the lower end of the large slider, a first insert on one side of the large slider, a core-pulling mechanism inserted inside the first insert, an inclined I-beam block engaged at the lower end of the core-pulling mechanism, a fixing block installed at the upper end of the large slider, an inclined guide post fixedly inserted inside the fixing block, and an inclined guide block fixedly connected to one end of the large slider. The utility model, through the large slider, hydraulic cylinder, inclined guide post, inclined guide block and core-pulling mechanism in the core-pulling assembly, can not only facilitate the quick demolding operation of car headlight bases or interior trim, but also improve the stability of the core-pulling structure and extend its service life.

[0004] Based on existing solutions and actual production and processing, the existing one-to-two slider motion structure of injection molds is not convenient for quickly removing the mold core structure. Therefore, we propose a one-to-two slider motion structure for injection molds to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a one-to-two slider motion structure for injection molds, so as to solve the problem mentioned in the background art that the existing one-to-two slider motion structure for injection molds is inconvenient for quickly removing the mold core structure.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a one-to-two slider motion structure for injection molds, comprising a first slider, a second slider, and a telescopic cylinder:

[0007] A connecting plate is fixed to the inner side of the first slider, and a groove is opened at the inner end of the first slider. A first spring is installed inside the first slider. An inclined guide post is provided in the groove. A second slider is provided inside the inclined guide post, and a third mold core is fixed to the outer end of the second slider. A first mold core and a second mold core are respectively provided on the left and right sides of the third mold core. A telescopic cylinder is provided behind the first slider. A mounting bracket is fixed to the output end of the telescopic cylinder. The telescopic cylinder is fixed to a limiting strip. A rectangular plate is fixed to the outer side of the second slider. A second spring is installed inside the connecting plate, and a locking block is fixed to the outer end of the second spring.

[0008] Preferably, the connecting plate has a first slider fixedly connected to both its left and right sides.

[0009] Preferably, the outer ends of both the first mold core and the second mold core are connected to inclined guide posts.

[0010] Preferably, the mounting bracket is fixedly connected to the rectangular plate.

[0011] Preferably, the limiting strip is provided with a slide rail inside, and the outer end of the first slider is located inside the slide rail of the limiting strip.

[0012] Preferably, the end of the first spring is in contact with the outer surface of the inclined guide post.

[0013] Preferably, the outer side of the second slider is in contact with the inner side of the first slider.

[0014] Preferably, the connection between the card block and the rectangular plate is a snap-fit ​​connection, and the card block is symmetrically arranged about the center line of the connecting plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the injection mold's one-to-two sliding block motion structure can quickly move the first mold core, the second mold core, and the third mold core into and out of the mold cavity, thereby improving demolding efficiency;

[0016] 1. When moving the first mold core, the second mold core, and the third mold core outward, the telescopic cylinder is activated. The telescopic cylinder first drives the second slider and the third mold core to move outward. At the same time as the second slider moves, the two sets of inclined guide pillars move, which in turn drive the first slider to move outward, so that the first mold core, the second mold core, and the third mold core can be quickly removed from the mold cavity.

[0017] 2. When the second slider is in contact with the outer side of the connecting plate, the locking block is inserted into the interior of the rectangular plate under the action of the second spring. Thus, when the first mold core, the second mold core and the third mold core need to be pushed into the mold cavity, the telescopic cylinder can first drive the mounting frame, the rectangular plate, the connecting plate, the first slider and the second slider to move together.

[0018] When the first slider touches the outer side of the mold and is blocked by the mold, the telescopic cylinder continues to push the second slider and the rectangular plate to move. The locking block slides out from the inside of the rectangular plate, and the second slider and the inclined guide post can then move inward to unfold the first mold core, the second mold core and the third mold core inside the mold cavity.

[0026] 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.

[0027] Please see Figures 1-5 The existing one-to-two slider motion structure of injection molds is not convenient for quickly removing the mold core structure. In order to solve this technical problem, this embodiment discloses the following technical content;

[0028] A one-to-two slider motion structure for injection molds includes a first slider 1, a connecting plate 2, a slide groove 3, a first spring 4, an inclined guide post 5, a first mold core 6, a second mold core 7, a second slider 8, a third mold core 9, a telescopic cylinder 10, a mounting bracket 11, a limiting strip 12, a rectangular plate 13, a second spring 14, and a locking block 15;

[0029] like Figure 1 As shown, a connecting plate 2 is fixed to the inner side of the first slider 1, and the first slider 1 is fixedly connected to both the left and right sides of the connecting plate 2. The outer side of the second slider 8 is in contact with the inner side of the first slider 1.

[0030] The inner end of the first slider 1 is provided with a groove 3, the first spring 4 is installed inside the first slider 1, and the inclined guide post 5 is provided in the groove 3. The end of the first spring 4 is in contact with the outer side of the inclined guide post 5.

[0031] A second slider 8 is provided on the inner side of the inclined guide post 5, and a third mold core 9 is fixed on the outer end of the second slider 8. A first mold core 6 and a second mold core 7 are provided on the left and right sides of the third mold core 9, respectively. The outer ends of the first mold core 6 and the second mold core 7 are connected to the inclined guide post 5. A telescopic cylinder 10 is provided behind the first slider 1. A mounting bracket 11 is fixed on the output end of the telescopic cylinder 10. The mounting bracket 11 is fixedly connected to the rectangular plate 13. The telescopic cylinder 10 is fixed on the limiting strip 12. A slide rail is provided inside the limiting strip 12. The outer end of the first slider 1 is located inside the slide rail of the limiting strip 12.

[0032] The telescopic cylinder 10 is activated, and under the action of the telescopic cylinder 10, the mounting bracket 11, the rectangular plate 13 and the second slider 8 are pulled outward. The second slider 8 slides outward inside the first slider 1, thereby moving the third mold core 9 outward. The rectangular plate 13 moves outward inside the connecting plate 2, losing the restriction of the second slider 8 and the third mold core 9. Under the elastic action of the first spring 4, the inclined guide post 5 slides inside the slide groove 3, thereby moving the first mold core 6 and the second mold core 7 outward.

[0033] When the second slider 8 moves to fit against the connecting plate 2, the first slider 1 moves outward following the second slider 8. At this time, under the elastic action of the second spring 14, the locking block 15 is locked into the groove of the rectangular plate 13. The first slider 1 moves outward on the limiting strip 12. The sliding rail in the limiting strip 12 limits the movement trajectory of the first slider 1, so that the first slider 1 moves stably, thereby pulling out the first mold core 6, the second mold core 7 and the third mold core 9. Under the action of the telescopic cylinder 10, it moves inward to realize the movement of one slider pulling two sliders.

[0034] When it is necessary to move the first mold core 6, the second mold core 7, and the third mold core 9 into the mold cavity, the telescopic cylinder 10 is activated. The output end of the telescopic cylinder 10 retracts. Since the rectangular plate 13 is connected to the connecting plate 2 through the second spring 14 and the locking block 15, the connecting plate 2 and the first slider 1 move inward. Figure 6As shown, the mold is located at the end of the limiting strip 12. When the first slider 1 moves to the outside of the mold cavity, it will be blocked by the mold. The telescopic cylinder 10 continues to act. Due to the thrust of the telescopic cylinder 10, the locking block 15 is dislodged from the inside of the rectangular plate 13. Thus, the telescopic cylinder 10 only pushes the second slider 8 to move inward. The two sets of inclined guide pillars 5 slide inside the slide groove 3, so that the first mold core 6, the second mold core 7 and the third mold core 9 are combined in the mold cavity.

[0035] The above completes a series of operations for the one-to-two slider motion structure of the injection mold. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.
