Description

Technical Field

[0001] This invention belongs to the field of casting mold technology, specifically a casting mold for a metal encapsulation shell. Background Technology

[0002] Casting molds are made by pre-forming the structural shape of a part from other easily formable materials, and then placing the mold into a sand mold. This creates a cavity in the sand mold that matches the dimensions of the part's structure. A fluid liquid is then poured into this cavity, and after the liquid cools and solidifies, the part of the desired shape is obtained. With the development needs of various electronics industries, metal encapsulation shells are widely used in aerospace, aviation, marine, field, radar, communications, weaponry, and other military and civilian fields.

[0003] A Chinese patent document with publication number CN214442967U describes a conveniently disassembled extrusion casting mold. By rotating the handle counterclockwise on an annular plate, the annular plate can drive the triangular plate to rotate. When the triangular plate contacts the guide plate, the guide plate will lift the arc plate under the action of the triangular plate. The arc plate can then drive the positioning rod to be pulled out of the positioning hole. Then, the insertion rod can be pulled out of the slot, thus completing the disassembly of the upper and lower molds. The disassembly of the upper and lower molds is extremely convenient.

[0004] However, in the process of implementing the above technical solution, the following technical problems were found:

[0005] Existing casting molds require ensuring that the casting fits the mold cavity when forming castings. However, when casting metal packaging shells, interference from the branch pipes on the surface of the metal packaging shell can easily prevent the metal packaging shell from being cast in one go, which is quite troublesome. Summary of the Invention

[0006] To overcome existing shortcomings, this application provides a casting mold for a metal encapsulation shell. By combining the second cavity inside the upper mold with the first cavity inside the lower mold, and combining multiple first cavities inside the upper mold with multiple second cavities inside the lower mold, and by sealing the channels on one side of the second and first cavities through a slide block, and allowing the core rod to extend between the first and second cavities, a metal encapsulation shell including the shell body and branch tubes can be easily formed between the upper and lower molds. This solves the problem that existing casting molds are prone to interference from the branch tubes on the surface of the metal encapsulation shell during casting, which can prevent the metal encapsulation shell from being cast in one go.

[0007] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0008] A casting mold for a metal encapsulation shell includes a three-part structure: an upper mold, a lower mold, and two fastening mechanisms. A second mold cavity is machined at the center of the bottom of the upper mold. Multiple first cavities are machined on both sides of the bottom of the upper mold, and the interiors of the multiple first cavities are connected to the interiors of the second mold cavities. Two positioning rods are fixedly connected to the four corners of the bottom of the upper mold. An injection port is machined inside the center of the upper mold.

[0009] The lower mold has a first mold cavity machined at the center of its top, and the upper mold has multiple second cavities machined on both sides of its top, with each of the multiple second cavities communicating with the interior of the first mold cavity.

[0010] Two symmetrically arranged fastening mechanisms are used to connect the upper mold and the lower mold. The fastening mechanism includes a vertical plate, a slide block is fixedly connected to the top of the vertical plate, a plurality of core rods are fixedly connected to one side of the slide block, and a limit plate is fixedly connected to the bottom of the vertical plate. A second slot and a first slot are machined on one side of both ends of the limit plate.

[0011] A metal encapsulation shell is formed between the upper mold and the lower mold. The metal encapsulation shell includes a shell body, and multiple branch tubes are integrally formed on the outer walls of both sides of the shell body. The shell body is formed between the first mold cavity and the second mold cavity.

[0012] In one possible implementation, the positioning rod is plugged into the inside of the corner of the lower mold, and the limiting plate located on one side is slidably connected to the bottom of the lower mold. A limiting groove is machined on the outer side of the bottom of the positioning rod.

[0013] In one possible implementation, the limiting plate is inserted into the outside of four positioning rods located on the same side, and the limiting plate is movably connected to the inside of the limiting groove.

[0014] In one possible implementation, an electric push rod is assembled to one side of the bottom of the limiting plate, and the fixed end of the electric push rod is assembled to the bottom of the lower mold.

[0015] In one possible implementation, the bottom end of the lower mold is fixedly connected to two support plates, which are symmetrically distributed on both sides of the two electric push rods. The thickness of the support plates is greater than the length of the portion of the positioning rod extending out of the lower mold.

[0016] In one possible implementation, two guide rods are fixedly connected to one side of the upright plate, and the guide rods are slidably connected inside the lower mold. Both sides of the lower mold are machined with storage slots, and the upright plate is movably connected inside the storage slots.

[0017] In one possible implementation, the bottom ends of both sides of the upper mold are machined with a first slide rail, and the top ends of both sides of the lower mold are machined with a second slide rail, and the slide block is slidably connected inside the first slide rail and the second slide rail.

[0018] In one possible implementation, the interior of the first slide is connected to the interior of the first cavity, the interior of the second slide is connected to the interior of the second cavity, and the surface of one side of the slide block is simultaneously in contact with the inner walls of the first and second slides.

[0019] In one possible implementation, the core rod is movably connected between the second cavity and the first cavity, and the branch pipe is formed within a channel formed by the core rod, the first cavity, and the second cavity.

[0020] The beneficial effects of this application are as follows:

[0021] Firstly, in this solution, by combining the second cavity inside the upper mold with the first cavity inside the lower mold, and combining the multiple first cavities inside the upper mold with the multiple second cavities inside the lower mold, and by sealing the channels on one side of the second and first cavities through the slide block, and after the core rod is inserted between the first and second cavities, molten metal is poured into the space between the upper and lower molds through the injection port, a metal encapsulation shell including the shell body and branch tubes can be formed between the upper and lower molds, which is simple and convenient.

[0022] Secondly, in this solution, by using an electric push rod to control the movement of the limiting plate at the bottom of the lower mold, the slide block is driven to slide between the first and second slide rails, controlling multiple core rods to exit between multiple first cavities and multiple second cavities, which facilitates the separation efficiency of the upper and lower molds and will not damage the multiple branch pipes on both sides of the shell.

[0031] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0032] Example 1:

[0033] This embodiment describes the specific structure of a casting mold for a metal packaging shell, as detailed in the following reference. Figures 1-7 As shown, it includes an upper mold 1, a lower mold 3 and two fastening mechanisms 6. A second mold cavity 14 is machined in the center of the bottom of the upper mold 1. Multiple first cavities 13 are machined on both sides of the bottom of the upper mold 1. Two positioning rods 5 are fixedly connected at the four corners of the bottom of the upper mold 1. An injection port 2 is machined inside the center of the upper mold 1.

[0034] The lower mold 3 has a first mold cavity 11 machined at the center of its top, and the upper mold 1 has multiple second cavities 15 machined on both sides of its top.

[0035] Among them, the interior of multiple first cavities 13 is connected to the interior of second mold cavities 14, and the interior of multiple second cavities 15 is connected to the interior of first mold cavities 11. After the positioning rod 5 is plugged into the interior of the corner of the lower mold 3, the upper mold 1 and the lower mold 3 are combined, and the metal solution can be poured from the interior of the injection port 2 between the upper mold 1 and the lower mold 3 to form the shell body 101 between the first mold cavity 11 and the second mold cavity 14.

[0036] Both of the two symmetrically arranged fastening mechanisms 6 include a vertical plate 67. The top of the vertical plate 67 is fixedly connected to a slide block 65. A plurality of core rods 66 are fixedly connected to one side of the slide block 65. The bottom of the vertical plate 67 is fixedly connected to a limiting plate 61. A second slot 64 and a first slot 63 are machined on one side of both ends of the limiting plate 61.

[0037] The interior of the first slide rail 8 is connected to the interior of the first cavity 13, and the interior of the second slide rail 9 is connected to the interior of the second cavity 15. When the surface of one side of the slide block 65 is simultaneously in contact with the inner walls of the first slide rail 8 and the second slide rail 9, the core rod 66 can be located between the second cavity 15 and the first cavity 13. A channel is formed on the surface of the core rod 66 with the first cavity 13 and the second cavity 15, which facilitates the formation of the branch pipe 102 in the channel.

[0038] Secondly, in order to enable multiple core rods 66 to extend into the corresponding first cavity 13 and second cavity 15, and to ensure that the core rods 66 are concentric with the circular grooves formed by the first cavity 13 and the second cavity 15, first slide rails 8 are machined at the bottom ends on both sides of the upper mold 1, and second slide rails 9 are machined at the top ends on both sides of the lower mold 3, so that the slide block 65 is slidably connected inside the first slide rails 8 and the second slide rails 9, with the first slide rails 8 and the second slide rails 9 forming the top of the slide block 65, thus restricting the slide block 65 from wobbling between the first slide rails 8 and the second slide rails 9.

[0039] By adopting the above technical solution:

[0040] The above design inserts multiple positioning rods 5 fixed at the four corners of the bottom of the upper mold 1 into the interior of the lower mold 3. After fixing the positioning rods 5 to the lower mold 3 using the limiting insert plate 61, the second mold cavity 14 inside the upper mold 1 can be combined with the first mold cavity 11 inside the lower mold 3, and the multiple first tubes 13 inside the upper mold 1 can be combined with the multiple second tubes 15 inside the lower mold 3. After the channel on one side of the second tube 15 and the first tube 13 is blocked by the slide 65, and the core rod 66 is inserted between the first tube 13 and the second tube 15, the metal solution is poured from the injection port 2 between the upper mold 1 and the lower mold 3. A metal encapsulation shell 10 including the shell body 101 and the branch tube 102 can be formed between the upper mold 1 and the lower mold 3, which is simple and convenient.

[0041] Meanwhile, when it is necessary to remove the metal encapsulation shell 10 from between the upper mold 1 and the lower mold 3, simply control the slide block 65 to slide between the first slide rail 8 and the second slide rail 9, so that the multiple core rods 66 can be disengaged from the interior of the multiple branch tubes 102, and the connection between the limiting insert plate 61 and the positioning rod 5 can be released, so that the upper mold 1 and the lower mold 3 can be separated, which is simple and convenient.

[0042] Example 2:

[0043] Based on Example 1, this example describes the specific structure of the casting mold for the metal encapsulation shell. An electric push rod 62 is assembled and connected to one side of the bottom of the limiting plate 61. The fixed end of the electric push rod 62 is assembled and connected to the bottom of the lower mold 3. A limiting groove 7 is machined on the outer side of the bottom of the positioning rod 5.

[0044] When the movable end of the electric push rod 62 retracts into the interior of the fixed end, the limiting plate 61 can slide at the bottom of the lower mold 3. At the same time, the vertical plate 67 drives the slide block 65 to slide between the first slide rail 8 and the second slide rail 9. The limiting plate 61 is inserted into the outside of the four positioning rods 5 on the same side, so that the limiting plate 61 is inserted into the interior of the limiting slide groove 7 to complete the limiting work.

[0045] Secondly, in order to facilitate the insertion of the positioning rod 5 into the interior of the lower mold 3, and to enable the electric push rod 62 to control the movement of the limiting plate 61 at the bottom of the lower mold 3, two support base plates 4 are fixed at the bottom of the lower mold 3. The two support base plates 4 are symmetrically distributed on both sides of the two electric push rods 62, and the thickness of the support base plates 4 is greater than the length of the part of the positioning rod 5 extending out of the interior of the lower mold 3, so as to avoid interference when the limiting plate 61 moves at the bottom of the lower mold 3.

[0046] Furthermore, in order to improve the stability of the movement of the limit plate 61 in the storage slot 12, two guide rods 68 are fixed on one side of the upright plate 67, so that the guide rods 68 are slidably connected to the inside of the lower mold 3.

[0047] By adopting the above technical solution:

[0048] The above design utilizes an electric push rod 62 to control the movement of the limiting plate 61 at the bottom of the lower mold 3. The upright plate 67, supported by two guide rods 68, drives the slide block 65 to slide between the first slide rail 8 and the second slide rail 9. This controls the multiple core rods 66 to exit or extend between the multiple first cavities 13 and the multiple second cavities 15. After the limiting plate 61 engages with four positioning rods 5 on the same side, the multiple core rods 66 can be installed between the multiple first cavities 13 and the multiple second cavities 15. After the limiting plate 61 disengages from the positioning rods 5, the core rods 66 exit between the first cavities 13 and the second cavities 15. This improves the efficiency of separating the upper mold 1 and the lower mold 3. During this process, the metal encapsulation shell 10 formed between the upper mold 1 and the lower mold 3 will not be damaged, making the design simple and convenient.

[0049] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
