Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy liquid forging die casting molds, and in particular to a modular connection structure for liquid forging core pulling mechanism. Background Technology

[0002] In low-pressure injection molding, the core-pulling mechanism is mostly directly connected to the drive mechanism and fixed with fasteners. In this type of mold, the connecting rod of the drive mechanism and the core-pulling mechanism are not much different in size, and the direct connection structure is beneficial for simplifying the design. However, in high-pressure casting, especially in metal injection molding, various direct connection structures have been developed due to the different sizes of the cores. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the purpose of this utility model is to provide a modular connection structure for liquid forging core pulling mechanism, so as to simplify the assembly structure between the drive mechanism and the core pulling mechanism.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A modular connection structure for a liquid forging core-pulling mechanism includes a connection module extending from the side of the mold core and connected to a core-pulling rod, and a drive mechanism for realizing core pulling by driving the connection module to move. The drive mechanism and the connection module are connected and fixedly connected by a modular adapter structure, which consists of an adapter rod and a fixing clamp sleeved on the end of the connecting rod between the adapter rod and the drive mechanism.

[0006] Furthermore, the inner side of the fixing clamp has a cavity and arc-shaped protrusions respectively disposed at both ends of the cavity. The outer periphery of the adapter rod is provided with a first protruding ring and a second protruding ring. When one end of the adapter rod is placed in the fixing clamp, the arc-shaped protrusion on one side of the fixing clamp is located between the first protruding ring and the second protruding ring to achieve mutual fixation. The outer periphery of the end of the connecting rod is also provided with a fourth protruding ring for cooperating with the arc-shaped protrusion on the other side of the fixing clamp to achieve fixation.

[0007] Furthermore, the fixing clip consists of a first half-clip and a second half-clip that are mirror images of each other.

[0008] Furthermore, the first half-clamp is connected to the control lever of the drive mechanism.

[0009] Furthermore, the first half-clamp and the second half-clamp are locked together by fasteners.

[0010] Furthermore, the adapter rod also has a third convex ring, which is located at both ends of the adapter rod, and the third convex ring is connected to the connecting module for transmission.

[0011] The beneficial effects of this utility model are as follows:

[0012] The modular connection structure for liquid forging core pulling mechanism provided by this utility model, by setting a transition between the connection module and the connecting rod, utilizes the annular structure of different sizes at both ends of the transition rod to enable the same connecting rod to match different core pulling connection modules through the transition structure. The annular structure also simplifies the assembly difficulty of the mechanism components and reduces the time spent on mold changing. Attached Figure Description

[0016] In the description of this utility model, it should be noted that the terms "upper", "lower", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. The above description is for the purpose of simplifying the description of this utility model and does not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0017] Exemplary embodiments of this application will now be described with reference to the accompanying drawings. However, it should be understood that this application can be presented in many different ways and is not limited to the embodiments described below. It should also be understood that the embodiments disclosed herein can be combined in various ways to provide further additional embodiments. Throughout the drawings, the same reference numerals denote the same or functionally identical elements.

[0018] Figure 1 and Figure 2 Specifically, a core-pulling module connection structure for aluminum alloy liquid forging dies is demonstrated. This structure includes an adapter rod 20 spanning between the connecting module 30 and the drive mechanism 51. The adapter rod 20 is connected to the connecting rod 53 via a fixing clip 40. The adapter rod 20 and the fixing clip 40 can be quickly disassembled and reassembled. This structure can be adapted to connecting rods 53 and connecting modules 30 with different designs, thus enabling its application in different dies.

[0019] Specifically, the outer circumferential surface of the adapter rod 20 is provided with several convex ring structures. The first convex ring 21 and the third convex ring 23 are located at the two ends of the adapter rod 20, respectively. The second convex ring 22 is located between the first convex ring 21 and the third convex ring 23, and is spaced apart from and not connected to the first convex ring 21 and the third convex ring 23. The two ends of the fixing clamp 40 are provided with arc-shaped protrusions 41. By inserting one end of the adapter rod 40 into the cavity 42 in the middle of the fixing clamp 40, the first convex ring 21 and the second convex ring 22 are used to lock the arc-shaped protrusions 41 from both sides, thus fixing the adapter rod 20 to the fixing clamp 40. Similarly, a fourth convex ring 54 is provided at the end of the connecting rod 53. The fourth convex ring 54 is locked into the cavity 42 to fix it to the fixing clamp 40, thereby connecting it to the adapter rod 20. The third protruding ring 23 is used to engage with the connecting module 30. This allows for the adaptation of connecting rods 53 and connecting modules 30 of different sizes and shapes by changing the length of the adapter rod 20. Furthermore, this modular connection structure facilitates easy assembly and disassembly, simplifying mold changing operations and shortening installation time. The drive mechanism 51 drives the connecting module 30 to move via the adapter rod 20. The connecting module 30 connects to the ejector pins within the mold core 10 to achieve the core-pulling function.

[0020] In one embodiment, the fixing clip 40 is designed to consist of a pair of first half-clamps 40a and second half-clamps 40b, and the split design facilitates the insertion of the adapter rod 20 and the connecting rod 53. The first half-clamps 40a and second half-clamps 40b are provided with connecting holes 43 for using fasteners to firmly clamp and fix the first half-clamps 40a and second half-clamps 40b together.

[0021] In another embodiment, a control lever 52 for providing stroke positioning control to the drive mechanism 51 is also connected to the first half-clamp 40a.

[0022] Unless otherwise specified, the singular forms “a,” “the,” and “the” used in this specification include the plural forms. The terms “comprising,” “including,” and “containing” used in this specification indicate the presence of the claimed feature, but do not exclude the presence of one or more other features.

[0023] When a component is described in the specification as being "on", "fixed" to, "connected" to, or "joined" to another component, the component may be directly located on, fixed to, connected to, joined to, or in contact with the other component, or there may be an intermediate component present.

[0024] It is understood that although the terms "first," "second," etc., may be used herein to describe different elements, these elements should not be limited by these terms. These terms are merely used to distinguish one element from another. Therefore, a first element may be referred to as a second element without departing from the teachings of this application.
