The application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0043] As part of the inventive concept of this application, before describing the embodiments of this application, it is necessary to analyze the process of workpiece ejection from the mold cavity in related technologies, and obtain the technical solution of the embodiments of this application through reasonable analysis.

[0044] The inclined ejector mechanism 10 is a component in the mold that can be used to form the undercut of the workpiece. The inclined ejector mechanism 10 cooperates with the mold core to define the undercut cavity 110. During the demolding process, the rod 12 of the inclined ejector mechanism 10 pushes the undercut out of the mold. In related technologies, the inclined ejector mechanism 10 directly inserts the rod 12 into the slide groove 111 of the mounting base 11 and sets a structure similar to a bushing on the outside of the rod 12, and then slides with the slide groove 111. As a result, the corresponding slide groove 111 and mounting base 11 are relatively large, and the movement space required for the rod 12 is also large, which leads to the problem that the slider 20 of the mold occupies a large space, and thus the manufacturing cost of the mold is high.

[0045] like Figures 1 to 3 As shown, one aspect of this application provides a mold, which includes a slider assembly 100 according to any embodiment of this application.

[0046] For example, the mold includes a mold body, which can be understood as an assembly of all other parts of the mold except for the slider assembly 100, or it can be an assembly of some parts. For example, the mold body includes a moving mold and a fixed mold. In the mold closed state, the moving mold, the fixed mold, and the slider assembly 100 define a cavity. The workpiece is formed in the cavity by injection molding or other methods. After the workpiece is formed, the mold switches from the mold closed state to the mold open state. The inclined ejector mechanism 10 of the slider assembly 100 can eject at least a portion of the workpiece from the cavity. The workpiece can be separated from the cavity wall, and at least a portion of the workpiece can also protrude from the cavity, thereby facilitating the removal of the workpiece.

[0047] Another embodiment of this application provides a slider assembly 100, which includes a main body 30, a slider 20, and at least one inclined actuation mechanism 10. The main body 30 has an installation space 31 and an opening communicating with the installation space 31. The slider 20 can enter or exit the installation space 31 through the opening in a first direction, and an installation cavity 21 is formed inside the slider 20, penetrating both ends of the slider 20 in the first direction. The inclined actuation mechanism 10 includes a mounting base 11, a rod 12, and a slider 13. The mounting base 11 is disposed on the main body 30 and located on the side of the installation space 31 away from the opening, and the rod 12 passes through the installation cavity 21. A groove 111 is formed on the side of the mounting base 11 away from the main body 30 in a second direction. The slider 13 is disposed on the end of the rod 12 away from the opening, and the slider 13 at least partially protrudes from the side of the rod 12 facing the mounting base 11 in the second direction and slides in cooperation with the groove 111, wherein the first direction and the second direction are perpendicular to each other.

[0048] The mold opening direction is the direction of movement of the moving mold during the process of switching the mold from the closed state to the open state. For example, the mold opening direction is the first direction.

[0049] For example, the main body 30 may be a base for engaging with the slider 20.

[0050] The number of inclined jacking mechanisms 10 can be one or more.

[0051] In the embodiments of this application, "multiple" refers to two or more items.

[0052] The slider 20 has an internal mounting cavity 21 that extends through both ends of the slider 20 in the first direction, and the rod 12 is slidably inserted into the mounting cavity 21.

[0053] For example, please refer to Figure 3 and Figure 4 The end of the rod 12 away from the mounting base 11 and the slider 20 define an undercut cavity 110 for the workpiece.

[0054] The rod 12 and the slider 20 cooperate to define the undercut cavity 110, and when the mold is ejected, the rod 12 of the inclined ejector mechanism 10 can push the undercut out of the mold.

[0055] One end of the rod 12 is slidably engaged with the mounting base 11 provided on the main body 30, and the other end is engaged with the slider 20.

[0056] For example, the second direction is the thickness direction of the mounting base 11. One side of the mounting base 11 along the thickness direction is in contact with the main body 30, and a groove 111 is formed on the side away from the main body 30 for sliding engagement with the rod 12. Thus, when the mold is closed or ejected, the rod 12 slides into the groove 111 via the sliding member 13.

[0057] The slider 13 may be partially protruding from the side of the rod 12 facing the mounting base 11 in the second direction, or it may be completely protruding from the side of the rod 12 facing the mounting base 11 in the second direction.

[0058] On a plane perpendicular to the second direction, the projections of the rod 12 and the slider 13 overlap.

[0059] The slider assembly 100 provided in this application embodiment includes a mounting base 11, a rod 12, and a slider 13. The mounting base 11 has a groove 111 formed on the side away from the main body 30 along the second direction. The slider 13 protrudes at least partially from the side of the rod 12 facing the mounting base 11 along the second direction. In other words, the slider 13 can slide and engage with the mounting base 11. Compared to the rod 12 directly extending into the groove 111 and sliding and engaging with it, this reduces the movement space required by the rod 12, or in other words, it reduces the size of the groove 111, which in turn reduces the space occupied by the mounting base 11. This improves the structural compactness of the slider assembly 100 and reduces its size, thereby reducing costs.

[0060] In some embodiments, please refer to Figures 1 to 3 The number of inclined jacking mechanisms 10 is multiple, and the multiple inclined jacking mechanisms 10 are arranged at intervals along a third direction, with the first direction, the second direction and the third direction being perpendicular to each other.

[0061] Please see Figures 1 to 3 The first direction is represented by X, the second direction by Y, and the third direction by Z.

[0062] By setting multiple inclined ejector mechanisms 10, the reliability of the mold can be improved. Furthermore, in embodiments where the product has multiple undercuts, the inclined ejector mechanisms 10 can cooperate to form multiple undercuts.

[0063] For example, the inclined top mechanism 10 corresponds one-to-one with the inverted buckle.

[0064] Understandably, since the size of the mounting base 11 can be reduced, especially in the third dimension, the gap between the rods 12 can also be reduced. This makes it possible to manufacture a size with a smaller gap between the undercuts, thus improving the applicability of the slider assembly 100 and its mold.

[0065] In some embodiments, please refer to Figure 5 The slider 13 includes a connecting portion 131 and a sliding portion 132. The connecting portion 131 is connected to the rod 12, and the sliding portion 132 is located within the groove 111. Projected onto a plane perpendicular to the second direction, the projection of the rod 12 overlaps the projection of the sliding portion 132.

[0066] For example, when projected onto a plane perpendicular to the second direction, the projection of the rod 12 overlaps the projection of the groove 111.

[0067] In other words, the cross-sectional dimension of the rod 12 is larger than the cross-sectional dimension of the groove 111, which helps to reduce the size of the mounting base 11.

[0068] In some embodiments, the slider 13 and the rod 12 are an integral structure.

[0069] This helps reduce the number of parts and improve the reliability of the inclined jack mechanism 10.

[0070] In other embodiments, the slider 13 is fastened to or welded to the rod 12.

[0071] For example, please refer to Figure 5 The sliding member 13 is inserted through the rod body 12 along the second direction. The sliding member 13 protrudes from the side of the rod body 12 away from the mounting base 11 to form a fastening part with a fastening hole. The sliding member 13 and the rod body 12 are fastened together by fasteners.

[0072] Of course, the slider 13 and the rod 12 can also be welded together.

[0073] In some embodiments, please refer to Figure 1 and Figure 5 The inclined top mechanism 10 includes a limiting ring 14, which is sleeved on the periphery of the sliding member 13 and clamped between the mounting base 11 and the rod 12.

[0074] The limiting ring 14, by being clamped between the mounting base 11 and the rod 12, helps to improve the sliding stability between the rod 12, the sliding member 13 and the mounting base 11, thereby improving the reliability of the slider assembly 100 and the mold.

[0075] In some embodiments, please refer to Figure 3 The rod 12 is tilted relative to the first direction.

[0076] In other words, the extension direction of the mounting cavity 21 is inclined relative to the first direction.

[0077] It should be noted that in embodiments where there are multiple inclined jacking mechanisms 10, different inclined jacking mechanisms 10 may be inclined in the same direction or in different directions relative to the first direction.

[0078] The tilt angles of different inclined jacking mechanisms 10 relative to the first direction can be the same or different.

[0079] The rod 12 is inclined relative to the first direction, so that when the mold is opened, the slider 20 and the rod 12 can be relatively displaced, which facilitates the undercut demolding.

[0080] In some embodiments, please refer to Figures 5 to 6 The chute 111 includes a first chute segment 112 and a second chute segment 113. The first chute segment 112 extends along a first direction, and the second chute segment 113 extends along a third direction. The first direction, the second direction, and the third direction are perpendicular to each other.

[0081] For example, since the rod 12 is inclined relative to the first direction, during the movement of the slider 20 along the first direction, the slider 20 can decompose the displacement of the rod 12 into the displacement in the first direction and the displacement in the third direction.

[0082] In the mold-closed state, the slider 13 is located in the second groove 113, which limits the slider 13 in the first direction. Thus, during the mold opening process, the slider 20 moves along the first direction toward the mounting base 11. Since the second groove 113 limits the slider 13 in the first direction, the rod 12 moves along the third direction under the action of the slider 20, that is, it slides along the second groove 113, but no displacement occurs in the first direction. At this time, the rod 12 separates from the slider 20 at the end near the opening (for easy mold parting with undercut). As the slider 20 continues to move along the first direction toward the mounting base 11, the slider 13 moves to the intersection of the first groove 112 and the second groove 113. At this time, the groove 111 limits the slider 13 in the third direction. Therefore, the rod 12 moves along the first direction under the action of the slider 20, that is, it slides along the first groove 112, but no displacement occurs in the third direction. During the mold closing process, the slider 20 drives the rod 12 and the sliding member 13 to reset together. The reset process is the reverse of the mold opening process described above, and will not be described in detail here.

[0083] In some embodiments, the dimensions of the mounting base 11 in the first direction are in the range of 80 mm to 150 mm.

[0084] The dimension of the mounting base 11 in the first direction can be any one of 80mm, 90mm, 100mm, 110mm, 120mm, 130mm, 140mm, 150mm or any combination thereof.

[0085] By setting the size of the mounting base 11 in the first direction to 80mm-150mm, the slide groove 111 of the mounting base 11 can be made appropriate, which can take into account both the movement space of the inclined top mechanism 10 and the structural compactness of the slider assembly 100.

[0086] In some embodiments, the mounting base 11 has a third-party dimension ranging from 30 mm to 80 mm.

[0087] The dimension of the mounting base 11 in the third direction can be any one of 30mm, 40mm, 50mm, 60mm, 70mm, 80mm or any combination thereof.

[0088] By setting the dimension of the mounting base 11 in the third direction to 30mm-80mm, the slide groove 111 of the mounting base 11 can be made appropriate, which can take into account both the movement space of the inclined top mechanism 10 and the structural compactness of the slider assembly 100.

[0089] In some embodiments, please refer to Figures 1 to 3 The slider assembly 100 includes a drive member 40, which is driven to connect with the slider 20 and is used to drive the slider to move along a first direction.

[0090] For example, the drive element 40 may be a hydraulic cylinder.

[0091] The number of drive components 40 can be one or more.

[0092] In embodiments where there are multiple driving elements 40, the multiple driving elements 40 are evenly distributed.
