[0002] At present, in the forming design of some housing components, especially the housing components used as the outer shell, there are usually fastening parts for connecting with another housing component. The number of such fastening parts is multiple. When the fastening parts are arranged on the same side of the housing component and adjacent to each other, multiple demoulding structures need to be set up to realize the demoulding of the housing component. Since the surface angles of each fastening part are different and the distance is too close, in the existing design, demoulding structures are usually set up separately for each fastening part. However, setting multiple demoulding structures on the same side of the die takes up a large amount of space, and there are disadvantages both in terms of cost and assembly difficulty. In addition, the design difficulty of setting up demoulding structures at multiple fastening parts with a short distance is also relatively large. Moreover, when multiple demoulding structures act simultaneously, it is easy to damage the product or cause defects in the formed part of the product. Content of the Utility Model

[0013] Further, an upper positioning groove for accommodating the upper part of the sliding seat is arranged on the upper template, the back of the sliding seat is arranged in an inclined plane, an upper positioning block with a surface shape matching that of the back of the sliding seat is arranged in the upper positioning groove, and the upper positioning block is adjustably arranged in the upper positioning groove through a plurality of bolts.

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] It should be understood that although terms such as upper, middle, lower, top, one end, etc. appear in this article to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish elements from each other for easy understanding, rather than to define any directional or sequential limitations.

[0038] As Figure 1-10 shown, a multi-directional slider demolding structure includes a lower mold core 1.1 and a lower template 1 connected to each other, an upper template 2 and an upper mold core 2.1 that are closed with the lower mold core 1.1 to form a cavity for the product 9, and a forming assembly disposed on the lower template 1. The forming assembly includes a slide seat 3 constrained to slide on the lower template 1, a first forming rod 4 fixedly disposed on the slide seat 3, and at least one second forming rod 5 lapped in the slide seat 3. An inclined pull rod 6 is provided on the upper template 2, and the inclined pull rod 6 passes through the slide seat 3, and the slide seat 3 is driven to slide in the lower template 1 through the inclined pull rod 6.

[0039] Among them, a plurality of adjacent fastening parts 9.1 are provided on the same side of the product 9. The first forming rod 4 and the second forming rod 5 are correspondingly arranged with the fastening parts 9.1 and constitute the forming surfaces of the fastening parts 9.1.

[0040] Preferably, the number of the second forming rods 5 is two, and they are respectively arranged on both sides of the first forming rod 4. The first forming rod 4 is arranged in the same direction as the moving direction of the sliding seat 3. Both of the two second forming rods 5 are inclined to the first forming rod 4, and the extending direction of the transmission groove 3.1 is the same as that of the second forming rod 5.

[0041] Specifically, the second forming rods 5 are adjacent to and inclined to the first forming rod 4, and both the first forming rod 4 and the second forming rod 5 are inserted into the lower die insert 1.1. Forming parts and transmission parts 5.1 are respectively arranged at both ends of the second forming rod 5. Forming surfaces are arranged on the forming parts. The forming parts are placed into the cavity and docked with the lower die insert 1.1. Transmission grooves 3.1 for the transmission parts 5.1 to be inserted are arranged on the sliding seat 3.

[0042] From Figure 4 it can be seen that in the closed mold state, an avoidance stroke 7 is arranged between the transmission groove 3.1 and the transmission part 5.1 along the demolding direction of the second forming rod 5.

[0043] During the mold opening process, the first forming rod 4 and the sliding seat 3 act synchronously. However, due to the avoidance stroke 7, the second forming rod 5 still remains at the closed mold position. The transmission part 5.1 and the transmission groove 3.1 are docked when the avoidance stroke 7 is consumed completely. The second forming rod 5 is ready to slide and demold along with the mold opening action. At this time, the first forming rod 4 disengages from the molding surface of the product 9, enabling the first forming rod 4 and the plurality of second forming rods 5 to sequentially perform demolding actions under the drive of the same sliding seat 3, effectively preventing the molding parts corresponding to the product 9 from being damaged and avoiding the interference problem between the first forming rod 4 and the second forming rod 5.

[0044] The utility model drives a plurality of forming rods to slide sequentially through a sliding seat 3, effectively reducing the manufacturing cost and being simple and convenient to install.

[0045] Among them, the first forming rod 4 and the sliding seat 3 are fixed by bolts, and extension parts embedded in the sliding seat 3 are arranged at both ends of the first forming rod 4 to ensure the action stability of the first forming rod 4.

[0046] Such as Figures 3 to 6As shown in the figure, as a further implementation of the cooperation between the second forming rod 5 and the transmission groove 3.1, an open groove 3.2 for the second forming rod 5 to pass through is provided on the transmission groove 3.1. The open groove 3.2 is arranged to open towards the lower die insert 1.1. In the closed die state, one side of the second forming rod 5 abuts against the groove wall of the open groove 3.2, so that the second forming rod 5 is supported by one side groove wall of the open groove 3.2 in the closed die state. And there is a clearance 8 between the other side of the second forming rod 5 and the other groove wall of the open groove 3.2. This clearance 8 is used to provide clearance for the second forming rod 5 during the demolding process. Due to the arrangement of the obliquely arranged second forming rod 5, as the slide block 3 slides horizontally during mold opening, the clearance 8 on one side between the second forming rod 5 and the open groove 3.2 gradually decreases, while the abutting part on the other side gradually moves away and forms a gap. In this way, the jamming and interference of the second forming rod 5 during mold opening are effectively avoided. Thus, the first forming rod 4 and the second forming rod 5 with adjacent and different angles are arranged on one slide block 3, and the buckling parts 9.1 or other shaped forming parts with different angles on the same side of the product 9 are satisfied.

[0047] Specifically, at least one side of the transmission part 5.1 extends with a first transmission convex part 5.2, a second transmission convex part 3.3 is arranged in the transmission groove 3.1, and the avoidance stroke 7 is arranged between the first transmission convex part 5.2 and the second transmission convex part 3.3.

[0048] Preferably, the first transmission convex part 5.2 extends on both sides of the transmission part 5.1, so that the transmission part 5.1 and the transmission groove 3.1 are arranged in a T shape. During mold opening, the first transmission convex part 5.2 and the second transmission convex part 3.3 abut against each other as the avoidance stroke 7 is consumed. At this time, the second forming rod 5 and the slide block 3 form a transmission cooperation.

[0049] Specifically, a first abutting part 5.3 is arranged at the end of the transmission part 5.1, and a second abutting part 3.4 is arranged at the end of the transmission groove 3.1. During mold closing, as the slide block 3 slides, the second abutting part 3.4 approaches and actuates the first abutting part 5.3, and pushes the second forming rod 5 to the mold closing position.

[0050] In this embodiment, to ensure the reliability of the mold closing and mold opening actions of the second forming rod 5 and the first forming rod 4, a guiding groove 1.2 for restricting the second forming rod 5 is arranged in the lower die insert 1.1. The guiding groove 1.2 is arranged in the same direction as the second forming rod 5, and the second forming rod 5 is located in the guiding groove 1.2 in both the closed die state and the open die state.

[0051] Specifically, a limiting portion 1.3 is provided on the guiding groove 1.2, and a cooperating portion 5.4 opposite to the limiting portion 1.3 is provided on the second forming rod 5. The limiting portion 1.3 and the cooperating portion 5.4 are in abutment in the mold-closed state and are spaced apart from the forming portion. The limiting portion 1.3 and the cooperating portion 5.4 are specifically arranged in a stepped manner, aiming to ensure the proper position of the second forming rod 5 during the mold-closing process, prevent the second forming rod 5 from disengaging from the lower mold core 1.1, and ensure the position stability of the second forming rod 5 within the lower mold core 1.1.

[0052] Among them, the guiding groove 1.2 is also correspondingly arranged for the first forming rod 4.

[0053] It is worth mentioning that the second forming rod 5 is constrained and guided by the guiding groove 1.2 within the lower mold core 1.1 to determine the position of the second forming rod 5 within the transmission groove 3.1, without the need to provide a fixed guiding structure between the transmission portion 5.1 of the second forming rod 5 and the transmission groove 3.1, thus simplifying the structure and reducing costs.

[0054] As a further implementation manner of the slider, the slide base 3 includes an upper slider 3.5 and a lower slider 3.6 fixedly spliced with each other. The transmission groove 3.1 is formed on the lower slider 3.6, and the upper slider 3.5 is arranged to close the transmission groove 3.1, thereby playing a role in vertically limiting the second forming rod 5. At least a part of the upper slider 3.5 is placed within the upper template 2 to increase the pressure on the slide base 3 in the mold-closed state and ensure the position stability of the slide base 3.

[0055] As Figure 2 shown, specifically, an upper positioning groove 2.2 for accommodating the upper part of the slide base 3 is provided on the upper template 2. The back of the slide base 3 is arranged in an inclined plane. An upper positioning block 2.3 with a surface shape matching that of the back of the slide base 3 is provided in the upper positioning groove 2.2, and the upper positioning block 2.3 is adjustably arranged in the upper positioning groove 2.2 through a plurality of bolts.

[0056] As Figure 9 shown, specifically, a lower positioning groove 1.4 for accommodating the lower part of the slide base 3 is provided on the lower template 1. A lower positioning block 1.5 is embedded in the lower positioning groove 1.4, and the lower positioning block 1.5 is adjustably arranged in the lower positioning groove 1.4 through a plurality of bolts. And an elastic positioning block 1.6 is embedded in the lower positioning plate. The end of the elastic positioning block 1.6 extends out of the lower positioning block 1.5. A positioning groove 3.8 matching the lower positioning block 1.5 is provided at the bottom of the slide base 3.

[0057] In this embodiment, the elastic positioning block 1.6 refers to a columnar convex block with a spring at the bottom, and the spring is not shown in the figure. Two positioning grooves 3.8 are provided at the bottom of the slide base 3, corresponding to the mold-closed position and the mold-open position of the slide base 3 respectively. When the slide base 3 moves into place, the elastic positioning block 1.6 cooperates with the bottom of the slide base 3 to play a certain positioning role.

[0058] Among them, both the upper positioning block 2.3 and the lower positioning block 1.5 adjust the plane through bolts, which is beneficial to improving the position stability of the slide block 3 in the mold closing state.

[0059] Such as Figure 7 and Figure 8 shown, specifically, guiding convex parts 3.7 are provided on both sides of the slide block 3 in an extended manner, guiding pressure plates 1.7 corresponding to the guiding convex parts 3.7 are provided in the lower positioning groove 1.4, the guiding pressure plates 1.7 extend into the lower positioning groove 1.4 and form a guiding channel 1.8, and the guiding convex parts 3.7 are arranged to penetrate through the guiding channel 1.8. Among them, the guiding pressure plates 1.7 are arranged in an adjustable manner through bolts. In this way, the smoothness of the slide block 3 during the sliding process can be ensured, and the vertical crosstalk can be reduced.

[0060] Referring to Figure 1 , in some other embodiments, a limiting protrusion 1.9 is further provided at the rear end of the slide block 3 in the lower positioning groove 1.4. The limiting protrusion 1.9 can be selected as a bolt, and a limiting recess 3.9 matching the limiting protrusion 1.9 is further provided at the end of the slide block 3. The limiting protrusion and the limiting recess 3.9 are abutted against each other at the mold opening limit position of the slide block 3, so as to provide reliable position constraint for the slide block 3.

[0061] This specific embodiment is only an interpretation of the present invention, and it is not a limitation of the present invention. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions according to needs, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
