Description

Technical Field

[0001] This utility model relates to the field of mold demolding technology, specifically a demolding structure for the inner sliding position of a multi-cavity female mold pull plate. Background Technology

[0002] Multi-cavity molds, also known as multi-cavity molds or family molds, are a special type of injection mold structure. They refer to a single mold containing multiple cavities of different shapes and functions, enabling the simultaneous production of matching products and greatly improving the efficiency of subsequent assembly and product consistency.

[0003] Currently, the demolding method for products in multi-cavity molds is usually achieved by using a pull plate and inner slides. The movement of the pull plate moves multiple inner slides (sliders), thereby removing the restriction on the product. Then, ejector pins push the molded product out of the moving mold. However, some slides are currently fixed to the mold core with bolts. Therefore, the mold core needs to move multiple slides within the mold plate to remove the restriction on the product. This not only increases the overall complexity of the multi-cavity mold, but the sliding of the mold core also causes wear on itself and the mold plate. Utility Model Content

[0004] The purpose of this invention is to provide a multi-cavity female mold pull plate inner sliding demolding structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] The multi-cavity female mold pull plate inner sliding demolding structure includes an upper sealing plate, a female template, a female mold core, a lower sealing plate, mold feet, a male template, a male mold core, a top plate one, and a top plate two. The bottom of the female template has an embedding groove, and the female mold core is placed in the embedding groove. Multiple snap-fit ​​parts that penetrate the female mold core are set in the embedding groove. The inside of the female mold core has an installation groove corresponding to the snap-fit ​​parts. A slider is slidably connected inside the installation groove. The top of the top plate one is fixedly connected to two symmetrical ejector pins one that penetrate the male template, male mold core, and female mold core. The top of the top plate two is fixedly connected to multiple ejector pins two corresponding to the cavity.

[0007] Furthermore, springs are fixedly connected to both ends of the bottom of the slider and the mounting groove, and a limiting post that slides through the slider is fixedly connected inside the mounting groove.

[0008] Furthermore, the snap-fit ​​component includes a connecting block that is fixed in the embedded groove by bolts, a convex block that is fixedly connected to the bottom of the connecting block, and two symmetrically arranged snap-fit ​​plates that are slidably connected to both ends of the convex block.

[0009] Furthermore, the side of the card plate is fixedly connected with an arc-shaped spring.

[0010] Furthermore, the top side of the card plate is provided with a groove that slides with the convex block, the top of both ends of the convex block are provided with sliding grooves, the top of the groove is provided with multiple spherical grooves, and the spherical grooves are provided with balls.

[0011] Furthermore, a connecting block is fixedly connected to the side opposite to the template, and a fixing block is fixedly connected to the side of the top plate corresponding to the connecting block. A hydraulic cylinder is provided between the connecting block and the fixing block at the corresponding position.

[0012] Furthermore, each of the opposite sides of the mother template is fixedly connected to a connecting column one, and a connecting column two is fixedly connected to the side of the top plate two at a corresponding connecting column one. A connecting plate is provided between the connecting column one and the connecting column two at the corresponding position. The connecting plate is fixedly connected to the connecting column one, and a sliding hole for the connecting column two to slide is provided through the side of the connecting plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The ejector pin moves the slider upward within the mounting slot, releasing the locking mechanism from restricting the product. A spring allows the ejector pin to disengage from the slider, enabling the slider to return to its original position. This eliminates the need for the female mold core to move within the embedding groove on the female mold plate, thereby reducing the overall complexity of the mold and preventing wear between the female mold core and the female mold plate, thus increasing the overall service life of the mold.

[0023] 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.

[0024] Please see Figure 1 - Figure 7 In this embodiment of the utility model, the multi-cavity female mold pull plate inner sliding demolding structure includes an upper sealing plate 1, a female template 2, a female mold core 3, a lower sealing plate 4, a mold foot 5, a male template 6, a male mold core 7, a top plate 1 8, and a top plate 2 9. The bottom of the female template 2 is provided with an embedding groove, and the female mold core 3 is set in the embedding groove. Multiple snap-fit ​​pieces 21 that penetrate through the female mold core 3 are provided in the embedding groove. The inside of the female mold core 3 is provided with an installation groove 31 corresponding to the snap-fit ​​pieces 21. A slider 32 is slidably connected inside the installation groove 31. The top of the top plate 1 8 is fixedly connected with two symmetrical ejector pins 1 81 that penetrate through the male template 6, the male mold core 7, and the female mold core 3 at the installation groove 31. The top of the top plate 2 9 is fixedly connected with multiple ejector pins 2 91 corresponding to the cavity.

[0025] Specifically, the upper sealing plate 1, the female mold plate 2, and the female mold core 3 are first fixed together with bolts to form the fixed mold. The lower sealing plate 4, the two mold feet 5, the male mold plate 6, the male mold core 7, the top plate 1 8, and the top plate 2 9 are fixed together with bolts to form the moving mold. When it is necessary to remove the product between the female mold core 3 and the male mold core 7, the top plate 1 8 first drives multiple ejector pins 1 81 to move upward. The upward-moving ejector pins 1 81 penetrate the cavity between the female mold core 3 and the male mold core 7, and contact the bottom of the slider 32 at the corresponding position, pushing the slider 32 upward. The upward-moving slider 32 can open the corresponding snap-fit ​​part 21, thereby releasing the restriction on the product. At this time, the product is attached to the male mold core 7. Then, by restoring the top plate 1 8 to its original position, and then... By separating the moving mold from the fixed mold, when the moving mold moves a certain distance, the top plate 2 9 disengages from the lower sealing plate 4 under the power of the moving mold. As the male mold core 7 continues to move, the product is ejected from the male mold core 7 under the action of multiple ejector pins 2 91, thus achieving product demolding. The ejector pin 1 81 causes the slider 32 to move upward in the mounting groove 31, releasing the locking part 21 from restricting the product. The spring 33 allows the slider 32 to return to its original position after the ejector pin 1 81 disengages from the slider 32. This eliminates the need for the female mold core 3 to move in the embedded groove on the female mold plate 2, thereby reducing the overall complexity of the mold and avoiding wear between the female mold core 3 and the female mold plate 2, increasing the overall service life of the mold.

[0026] Example 1

[0027] like Figure 3 and Figure 4 As shown, in this embodiment, springs 33 are fixedly connected to both ends of the bottom of the slider 32 and the mounting groove 31. A limiting post 34 that slides through the slider 32 is fixedly connected inside the mounting groove 31. The snap-fit ​​component 21 includes a connecting block 211 fixed in the embedded groove by bolts. A convex block 212 is fixedly connected to the bottom of the connecting block 211. Two symmetrically arranged snap plates 213 are slidably connected to both ends of the convex block 212. An arc-shaped spring piece 214 is fixedly connected to the side of the snap plate 213. A groove 215 that slides with the convex block 212 is opened on the top of the side of the snap plate 213. A sliding groove is opened on the top of both ends of the convex block 212. A plurality of spherical grooves are opened on the top of the inner side of the groove 215. A ball bearing 216 is arranged in the spherical groove.

[0028] In this embodiment, when the slider 32 moves toward the fixed mold, it can push open the two end plates 213 of the connecting block 211 at the same end, thereby increasing the distance between the bottoms of the two plates 213 at the opposite positions, so that the bottom of the plates 213 disengages from the product's undercut. When the slider 32 returns to its original position, the plates 213 also begin to return to their original position under the elastic action of the arc-shaped spring 214. By setting multiple balls 216 on the top of the groove 215 and having the balls 216 slide within the sliding groove, the friction between the plates 213 and the convex block 212 can be reduced.

[0029] Example 2

[0030] like Figure 1 , Figure 6 and Figure 7 As shown, in this embodiment, a connecting block is fixedly connected to the opposite side of the male template 6, and a fixing block 82 is fixedly connected to the side of the top plate 8 at the corresponding connecting block. A hydraulic cylinder 83 is provided between the connecting block and the fixing block 82 at the corresponding position. A connecting column 1 is fixedly connected to the opposite side of the female template 2. A connecting column 2 92 is fixedly connected to the side of the top plate 9 at the corresponding connecting column. A connecting plate 22 is provided between the connecting column 1 and the connecting column 2 92 at the corresponding position. The connecting plate 22 is fixedly connected to the connecting column 1. A sliding hole 23 for the sliding of the connecting column 2 92 is provided through the side of the connecting plate 22.

[0031] In this embodiment, the top plate 8 can be moved by driving the two hydraulic cylinders 83. The movement of the top plate 8 towards the fixed mold can be controlled by multiple ejector pins 81 pushing multiple sliders 32 to move, thereby controlling the opening and closing of the snap-fit ​​part 21. When the moving mold moves and separates from the fixed mold, the movement of the moving mold can cause the two connecting pins 92 to slide in the corresponding sliding holes 23. When the moving mold moves a certain distance (that is, the connecting pins 92 move to the end of the sliding holes 23), the connecting plate 22 limits the top plate 9 through the connecting pins 92 to prevent the top plate 9 from continuing to move. At this time, the multiple ejector pins 91 on the top plate 9 penetrate the top plate 8, the male mold plate 6 and the male mold core 7, and eject the product on the male mold core 7, thereby completing the demolding of the product.
