Description

Technical Field

[0001] This application relates to the field of forming mold technology, and in particular to a composite forming mold suitable for support rods and lever hooks. Background Technology

[0002] Both the support rod and the lever hook are internal parts of fire-fighting equipment. They are typically manufactured using powder metallurgy pressing, followed by sintering to improve their structural strength. However, bending can occur during transportation or sintering, reducing the yield rate of the support rod and lever hook. Therefore, there is an urgent need for a composite forming mold suitable for both the support rod and the lever hook. Utility Model Content

[0003] The purpose of this utility model is to address the defects and shortcomings of the existing technology by providing a composite shaping mold suitable for support rods and lever hooks.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: The assembly includes a top plate, an upper template, a middle template, a lower template, and a base. The top plate, upper template, middle template, lower template, and base are arranged from top to bottom. A shaping component is provided between the upper template, middle template, and lower template. The shaping component includes an upper pressing component, a middle plate, and a lower pressing component. The upper pressing component is located inside the upper template, the middle plate is located inside the middle template, and the lower pressing component is located inside the lower template. The upper pressing component includes an upper pressure plate, an upper support block, and an upper lever block. One end of the upper support block and the upper lever block are respectively fixed below the upper pressure plate. The lower pressing component includes a lower pressure plate, a lower support block, and a lower lever block. One end of the lower support block and the lower lever block are respectively fixed above the lower pressure plate. The side walls of the middle plate are respectively provided with support rod grooves and lever hook grooves. The upper support block and the lower support block are respectively inserted into the support rod grooves, and the upper lever block and the lower lever block are respectively inserted into the lever hook grooves.

[0005] Preferably, the upper template has an upper mounting hole on its side wall, the upper pressure plate is located in the upper mounting hole, the corresponding two side walls of the upper pressure plate have first limiting blocks, and the upper template has a first limiting groove on the side wall of the upper mounting hole for the first limiting blocks to be embedded.

[0006] Preferably, the upper template is installed and fixed to the top plate, and the top plate locks the upper pressure plate onto the upper template.

[0007] Preferably, the lower template includes a first template and a second template. The side wall of the first template has a lower mounting hole, and the lower pressure plate is located in the lower mounting hole. The corresponding side walls of the lower pressure plate have second limiting blocks. The first template has a second limiting groove on the side wall of the lower mounting hole for the second limiting blocks to be inserted. The second template can lock the lower pressure plate onto the first template.

[0008] Preferably, the side wall of the intermediate template has a central mounting hole, a bracket is installed in the central mounting hole, and the intermediate plate is embedded in the bracket.

[0009] Preferably, an adjustment assembly is provided between the lower template and the base. The adjustment assembly includes a fixed seat, a locking ring, and an adjustment sleeve. One end of the fixed seat is fixed to the base, one end of the adjustment sleeve is threaded to the periphery of one end of the fixed seat, and the locking ring is threaded to rotate around the periphery of one end of the fixed seat and abuts against one end of the adjustment sleeve.

[0010] Preferably, a guide rod is provided between the middle template and the base, and the lower template is sleeved and slidably moved around the guide rod.

[0011] In summary, this application includes at least one of the following beneficial technical effects: 1. When the support rod and lever hook need to be shaped, the sintered support rod and lever hook are placed into the support rod groove and lever hook groove respectively. Under the action of the lower pressing component in the lower template, the support rod and lever hook are located in the support rod groove and lever hook groove respectively. Then, under the action of the hydraulic press, the top plate is driven to move down, thereby driving the upper template to move down, so that the lower support block and lower lever block of the lower pressing component are inserted into the support rod groove and lever hook groove respectively. Then, under the mutual squeezing of the upper pressing component and the lower pressing component, the support rod and lever hook are shaped, thereby flattening the bent support rod and lever hook and improving the pass rate of the support rod and lever hook. 2. During the shaping process of the forming mold, the adjusting sleeve can be rotated to move the adjusting sleeve away from or closer to the fixed seat, thereby changing the distance between the base and the lower template. This changes the portion of the lower support block and the lower lever block of the lower pressing component that are inserted into the support rod groove and the lever hook groove, respectively, thereby changing the pressure applied to the support rod and the lever hook.
