Description
Technical Field
[0001] This utility model relates to the field of aluminum processing technology, and in particular to a hot working mold for aluminum rods. Background Technology
[0002] In the field of aluminum processing technology, aluminum rod hot forming molds are key equipment for forming aluminum rods. Their core function is to complete the process steps of injecting molten aluminum, cooling and solidifying it, and removing the finished product through the closing and opening of the mold. With the diversified needs of the aluminum processing industry, frequent mold changes are required to adapt to different product specifications when producing different types of aluminum rods (such as cylindrical and hexagonal prism shapes). However, existing aluminum rod hot forming molds have significant shortcomings in practical applications:
[0003] Traditional molds are typically fixed to the upper and lower frames using methods such as bolting, welding, or interference fits. While these methods ensure mold stability, installation requires aligning and tightening each bolt individually, and disassembly requires tools to remove each bolt individually, making the process cumbersome and time-consuming. For large molds or scenarios requiring frequent replacements, this not only increases the labor intensity of workers but also extends equipment downtime, severely impacting production efficiency.
[0004] Secondly, the existing fixed structures of molds and frames often lack flexibility, making it difficult to quickly adapt to different mold models. When producing aluminum bars of different specifications, the entire mold assembly must be replaced, or even the frame structure adjusted, resulting in high production line adjustment costs and long cycles, failing to meet the flexible production needs of small batches and multiple varieties. Therefore, this paper provides a thermal processing mold for aluminum bars to solve the above-mentioned technical problems. Utility Model Content
[0005] The purpose of this utility model is to provide a hot working mold for aluminum rods to address the shortcomings of existing technologies, thereby solving the technical problem that existing molds are inconvenient to install or disassemble and replace.
[0006] To achieve the above objectives, the technical solution of this utility model is as follows:
[0007] A hot working mold for aluminum bars includes an upper frame and a lower frame that can move toward or away from each other. The upper and lower frames have mounting grooves formed on their adjacent sides. An upper mold is detachably installed in the mounting groove of the upper frame, and a lower mold for cooperating with the upper mold is detachably installed in the mounting groove of the lower frame. A plurality of first clamping mechanisms for clamping and fixing the lower mold are installed in the lower frame, and a plurality of second clamping mechanisms for clamping and fixing the upper mold are installed in the upper frame.
[0008] Furthermore, an injection port is provided at the top of the upper frame. After the lower mold and the upper mold are closed, a mold cavity is formed inside both, and the injection port is connected to the mold cavity.
[0009] Furthermore, a fixed frame is installed on the side of the frame, and a movable frame is installed on the side of the upper frame. The movable frame is movably mounted on the fixed frame.
[0010] Furthermore, the upper frame is provided with several guide rods on the side near the lower frame, the length of which is parallel to the direction of movement of the movable frame. The lower frame is provided with a guide sleeve on the side near the upper frame, which is fitted over the guide rods. The guide rods and the guide sleeve are slidably arranged.
[0011] Furthermore, a pair of first clamping mechanisms are provided and are respectively placed on the front and rear sides of the lower mold, and a pair of second clamping mechanisms are provided and are respectively placed on the left and right sides of the upper mold.
[0012] Furthermore, the first clamping mechanism includes a receiving groove formed on the inner side wall of the mounting groove of the lower frame, a clamping block rotatably provided in the receiving groove, a clamping groove formed on the side of the lower mold, and the side of the clamping block being inserted into the clamping groove to clamp and fix the lower mold in the mounting groove of the lower frame; a clearance portion is formed on the side of the clamping block, which is used to disengage the clamping block after rotation from the clamping groove.
[0013] Furthermore, the first clamping mechanism also includes a rotating rod positioned above the receiving groove and rotatably mounted on the lower frame. The rotating rod is arranged vertically, with its bottom end fixed to the top of the clamping block, and its top end is equipped with a driving component positioned on the top of the lower frame 1. The driving component is formed with a driving groove.
[0014] Furthermore, the edge of the side of the card block has a first bevel, and the slot opening has a second bevel.
[0015] Furthermore, a limiting groove is formed at the top of the lower frame, the driving component is placed in the limiting groove, and a limiting block is provided on the side of the driving component to cooperate with the limiting groove to limit its rotation angle.
[0016] The beneficial effects of this utility model are as follows: Before use, after the lower mold is installed into the mounting slot of the lower frame, the first clamping mechanism is controlled to clamp and fix the upper mold. After the upper mold is installed into the mounting slot of the upper frame, the second clamping mechanism is controlled to clamp and fix the upper mold, thus completing the installation of the upper and lower molds. The installation is simple and convenient. When it is necessary to replace the upper and lower molds, the operator can unlock the first and second clamping mechanisms to remove and replace the upper and lower molds. Both the lower and upper molds are detachable, which facilitates the replacement of different mold models to produce different types of aluminum rods, improving the adaptability of the products and meeting diverse production needs.

[0025] The following is a detailed description of a thermal processing mold for aluminum rods according to the present invention, with reference to the accompanying drawings.
[0026] like Figure 1-4 As shown, an embodiment of the aluminum rod hot processing mold of this utility model includes an upper frame 2 and a lower frame 1 arranged vertically. Each of the upper frame 2 and the lower frame 1 has a mounting groove 10 formed on its adjacent side. An upper mold 6 is installed in the mounting groove 10 of the upper frame 2, and a lower mold 5 for use with the upper mold 6 is installed in the mounting groove 10 of the lower frame 1. A liquid injection port 9 is provided at the top of the upper frame 2. When the upper mold 6 is installed in the mounting groove 10 of the upper frame 2, it is connected to the liquid injection port 9. The liquid injection port 9 is connected to an external melting device (not shown in the figure) for providing liquid aluminum solution. When the lower mold 5 and the upper mold 6 are closed, a mold cavity is formed inside them. Liquid aluminum solution is injected into the mold cavity from the liquid injection port 9 and fills the entire mold cavity space. After the filling stage is completed, the melting device stops operating to cool the liquid aluminum in the mold cavity. Finally, the upper frame 2 is controlled to move upwards, so that the upper mold 6 moves upwards along with it, causing the lower mold 5 to separate from the upper mold 6, thus completing the production of the aluminum rod.
[0027] A fixed frame 3 is installed on the side of the lower frame 1, and a movable frame 4 is installed on the side of the upper frame 2. The movable frame 4 is vertically mounted on the fixed frame 3. The fixed frame 3 contains a drive component (not shown in the figure) for controlling the vertical movement of the movable frame 4. The drive component is existing technology and can be a cylinder or hydraulic cylinder, etc. By operating the drive component, the movable frame 4 is controlled to move up and down on the fixed frame 3, thereby moving the upper frame 2 towards or away from the lower frame 1, realizing the automatic separation or closure of the lower mold 5 and the upper mold 6. In order to accelerate curing, both the upper frame 2 and the lower frame 1 are provided with connection ports 13. The connection ports 13 are connected to external cooling equipment (not shown in the figure) for providing coolant. The upper frame 2 and the lower frame 1 are provided with channels (not shown in the figure) for coolant to flow through. After the liquid aluminum solution is injected into the mold cavity, the coolant enters the interior of the upper frame 2 and the lower frame 1 through the connection port 13, carrying away the heat generated by the liquid aluminum solution and accelerating cooling and solidification. This cooling method is existing technology and will not be described in detail here.
[0028] Several guide rods 8 are provided on the side of the upper frame 2 near the lower frame 1, with their length direction parallel to the direction of movement of the movable frame 4. A guide sleeve 7 is provided on the side of the lower frame 1 near the upper frame 2, which is fitted over the guide rods 8. The guide rods 8 and the guide sleeve 7 are slidably connected. By setting the guide rods 8 and the guide sleeve 7, the upper frame 2 can move more stably in the direction of moving towards or away from the lower frame 1; and under the action of the guide sleeve 7, the guide rods 8 can slide within a specified range, limiting the range of movement of the upper frame 2.
[0029] In this embodiment, both the lower mold 5 on the lower frame 1 and the upper mold 6 on the upper frame 2 are detachable, allowing for the replacement of different mold types to produce different types of aluminum rods (cylindrical or hexagonal prism). To achieve detachability, several first clamping mechanisms 11 are installed in the lower frame 1 to clamp and fix the lower mold 5, and several second clamping mechanisms 12 are installed in the upper frame 2 to clamp and fix the upper mold 6. After the lower mold 5 is inserted into the mounting slot 10 of the lower frame 1, the first clamping mechanisms 11 can be controlled to clamp and fix the upper mold 6. After the upper mold 6 is inserted into the mounting slot 10 of the upper frame 2, the second clamping mechanisms 12 can be controlled to clamp and fix the upper mold 6. When it is necessary to replace the upper mold 6 and the lower mold 5, the operator can unlock the first clamping mechanisms 11 and the second clamping mechanisms 12 to remove and replace the upper mold 6 and the lower mold 5.
[0030] The first clamping mechanism 11 is provided in pairs and is respectively placed on the front and rear sides of the lower mold 5. The second clamping mechanism 12 is provided in pairs and is respectively placed on the left and right sides of the upper mold 6. This arrangement is to improve the clamping and fixing effect and stability, and to prevent the upper mold 6 and the lower mold 5 from automatically separating. The two have the same structure and the same operation mode, only the setting position is different.
[0031] like Figure 5-6 As shown, the first clamping mechanism 11 includes a receiving groove 111 formed in the inner side wall of the mounting groove 10 of the lower frame 1. A clamping block 112 is rotatably provided in the receiving groove 111. A clamping groove 115 is formed on the side of the lower mold 5. The side of the clamping block 112 is inserted into the clamping groove 115 to clamp and fix the lower mold 5 in the mounting groove 10 of the lower frame 1. A clearance portion 116 is formed on the side of the clamping block 112. The clearance portion 116 is used to disengage the clamping block 112 after rotation from the clamping groove 115 to unlock the lower mold 5. When it is necessary to unlock the lower mold 5, the control block 112 rotates around the vertical axis in the receiving groove 111. After rotating until the clearance part 116 is aligned with the slot 115, the side of the block 112 disengages from the slot 115. The clearance part 116 is arranged vertically and flat. When aligned with the slot 115, it is flush with the inner side wall of the mounting groove 10, or placed in the receiving groove 111. When the lower mold 5 is taken out from the mounting groove 10 of the lower frame 1, the block 112 does not block the lower mold 5, thus unlocking is achieved.
[0032] The first clamping mechanism 11 also includes a rotating rod 113 positioned above the receiving groove 111 and rotatably mounted on the lower frame 1. The rotating rod 113 is vertically arranged, with its bottom end fixed to the top of the locking block 112, and its top end equipped with a driving member 114 positioned on the top of the lower frame 1. The driving member 114 is formed with an internal hexagonal driving groove, which is used to fit an internal hex wrench (a type of screwdriver in the prior art). After the operator uses the internal hex wrench to turn the driving member 114, they can control the locking block 112 to rotate within the receiving groove 111, so that the locking block 112 is in one of two states: engaged in the locking groove 115 or disengaged from the locking groove 115. The driving groove can also be a slotted groove, a Phillips head groove, or a Torx groove, etc., with different grooves corresponding to different tools.
[0033] In this embodiment, a first beveled edge 117 is formed on the side edge of the card block 112, and a second beveled edge 118 is formed at the opening of the card slot 115. During the process of the card block 112 being rotated into the card slot 115, the first beveled edge 117 and the second beveled edge 118 guide the card block 112 into the card slot 115, which improves the convenience of inserting the card block 112 into the card slot 115.
[0034] A limiting groove 119 is formed at the top of the lower frame 1. The driving member 114 is placed in the limiting groove 119. A limiting block 1110 is provided on the side of the driving member 114 to cooperate with the limiting groove 119 to limit the angle of its rotation. When the driving member 114 rotates, it carries the limiting block 1110 to rotate around the axis of the rotating rod 113. The limiting block 1110 moves within the limiting groove 119, and the limiting groove 119 limits the limiting block 1110, so that the maximum angle of rotation of the driving member 114 is 180 degrees. Specifically: When the limiting block 1110 is placed at one end of the limiting groove 119, the locking block 112 engages in the locking slot 115 to secure the lower mold 5. When the driving component 114 rotates 180 degrees, the limiting block 1110 moves to the other end of the limiting groove 119. At this time, the accommodating part 116 aligns with the locking slot 115, and the locking block 112 disengages from the locking slot 115, thus unlocking the lower mold 5. By setting the limiting groove 119 and the limiting block 1110, the accuracy of adjusting the locking block 112 in both states (engaged or disengaged from the locking slot 115) is improved.
[0035] Additionally, an insert 1111 is provided at the bottom of the upper frame 2 to embed into the limiting groove 119 to prevent the limiting block 1110 from moving automatically. When the lower mold 5 and the upper mold 6 are closed, the insert 1111 embeds into the limiting groove 119, preventing the limiting block 1110 from moving automatically within the limiting groove 119 due to vibration during prolonged use of the mold, thus preventing the locking block 112 from automatically disengaging from the locking slot 115 and improving the stability of the heat treatment mold. Furthermore, when the insert 1111 cannot be embedded into the limiting groove 119, the lower mold 5 and the upper mold 6 cannot be closed, prompting the operator to perform adjustments. The insert 1111, which cooperates with the second locking mechanism 12, is located at the top of the lower frame 1.
[0036] This heat treatment mold also includes a support frame 14 and a rotating shaft 15 rotatably mounted on the support frame 14. The rotating shaft 15 is arranged laterally. The fixed frame 3 is provided with a connecting frame 16, and the connecting frame 16 is fixedly connected to the rotating shaft 15. The support frame 14 supports the upper frame 2 and the lower frame 1, and is used to place this heat treatment mold in a designated position. In addition, by controlling the rotating shaft 15 to rotate 90 degrees on the connecting frame 16, the upper frame 2 and the lower frame 1 can also rotate 90 degrees. After the lower mold 5 and the upper mold 6 separate, the formed aluminum rod automatically falls out, which facilitates the removal of the aluminum rod.
[0037] In summary, this utility model possesses the aforementioned excellent characteristics, enabling it to achieve unprecedented efficiency in use and thus become a highly practical product.
[0038] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of this utility model. The content of this specification should not be construed as a limitation of this utility model.
