Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a corrosion-resistant cemented carbide forming mold. Background Technology

[0002] In today's highly industrialized era, numerous industries, such as automotive manufacturing, aerospace, and electronics, place extremely stringent demands on the forming precision of components. Key components in the aerospace field, such as turbine blades, have complex shapes and require extremely high forming precision. Under high-temperature operating environments, ordinary mold materials cannot withstand prolonged thermal cycling and mechanical stress, easily leading to cracks and deformation, affecting the aerodynamic performance and structural integrity of the blades. Therefore, there is an urgent need for a mold material with excellent corrosion resistance and high precision retention to ensure the production quality of these high-precision components. With the continuous development of the global economy, market demand for various products is increasing, and mass production has become the mainstream mode of industrial production. In the process of mass production, the service life of the mold directly affects production costs and efficiency. If the mold life is short, frequent mold replacements will not only increase production costs but also reduce production efficiency, affecting the company's market competitiveness. Hard alloy, as a composite material composed of refractory metal carbides and a binder phase metal, has advantages such as high hardness, high strength, and good wear resistance, and has been widely used in the mold manufacturing field. In recent years, with the continuous development of materials science and technology, the performance of hard alloy has been further optimized.

[0003] In modern industrial production, the demand for high-precision, corrosion-resistant parts is increasing. Traditional mold materials, such as ordinary steel molds, have certain problems during use, such as the inconvenience of replacing the upper and lower molds, leading to increased production costs. On the other hand, some non-hard alloy materials cannot be easily processed in terms of hardness and strength, and there is also the problem of inconvenience in removing the parts after processing. Therefore, we propose a corrosion-resistant hard alloy forming mold to solve this problem. Utility Model Content

Two L-shaped sliders are integrally formed at the bottom end of each clamping plate. A sliding groove matching the L-shaped sliders and spiral blocks is opened at the top of the worktable.

[0008] Preferably, the heating assembly includes: a support block and a motor. The support block is fixedly installed on one side of the outer casing. Two electric push rods are fixedly installed inside the support block. The output ends of the two electric push rods are fixedly installed on the same moving block. The motor is fixedly installed on one side of the moving block. Two heating rollers are rotatably installed inside the moving block.

[0013] In this utility model, a corrosion-resistant hard alloy forming mold is described. By starting motor two, motor two drives the threaded rod to rotate.

In this way, the two heating rollers will heat the blank and transmit the material into the device at the same time.

[0014] In this utility model, a corrosion-resistant hard alloy forming mold is described. By activating a hydraulic cylinder fixedly installed at the top of the outer shell, the output end of the hydraulic cylinder pushes the connecting block downward, and at the same time drives the upper pressure block to move downward, thereby achieving mold closing. Two sliding pressure plates slidably installed inside the worktable move along the sliding grooves that match the sliding pressure plates and round rods opened in the worktable under the drive of motor three through a rotating disk, connecting rod one, connecting rod two and other transmission mechanisms. This squeezes and lifts the triangular block and the lifting block, lifting the squeezed material from the lower mold, making it convenient to open the rotating door to remove the material after processing, and to take out the formed corrosion-resistant hard alloy product from the mold.

[0015] This utility model has a reasonable structural design. The clamping component can stably clamp the lower mold, ensuring that the lower mold will not move during the pressing process, thus improving the quality of the molded product. The heating component uses two heating rollers that rotate synchronously in opposite directions to heat the alloy material, which can make the alloy material heat evenly, improve its plasticity, and facilitate pressing. The material is then transmitted into the device, and the lifting block is moved upward by the motor to push the molded product out of the lower mold. The operation is simple and convenient, improving production efficiency. Attached Figure Description
