Description

Technical Field

[0001] This utility model belongs to the technical field of mold steel, and more specifically, it relates to a high-toughness and high-wear-resistant mold steel. Background Technology

[0002] Mold steel is characterized by high strength and wear resistance. During the production process, after casting, it needs to undergo high-temperature forging to increase its density and shape. During high-temperature forging, mold steel is generally forged into rectangular steel ingots, plates, or round bars, and then further processed according to subsequent usage requirements.

[0003] Based on the above, the inventors have discovered the following problems: When mold steel is produced and stacked, since most mold steel is rectangular, it is large in volume and heavy in weight. The existing stacking method is to stack all the mold steel in sequence, which is inconvenient for subsequent handling. At the same time, there are basically no protective measures after the mold steel is stacked, which makes it easy for the edges and corners of the mold steel to be damaged, directly affecting the quality of the mold steel.

[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings to provide a high-toughness and high-wear-resistant mold steel, in order to achieve a more practical value. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a high-toughness, high-wear-resistant mold steel, which solves the problems of poor wear resistance of current mold steels and the fact that they are often stacked together during use, making them inconvenient to handle and easily causing damage to the edges and corners of the mold steel.

[0006] The purpose and effect of this utility model of a high-toughness and high-wear-resistant mold steel are achieved by the following specific technical means:

[0007] A high-toughness, high-wear-resistant mold steel includes a mold steel body. A mounting block is provided at the bottom of the mold steel body. Sleeve rods are rotatably connected to the four corners of the mounting block. Bolts are threaded to one side of each sleeve rod. A connecting rod is provided inside the sleeve rod. Several adjusting holes are provided on one side of the connecting rod, and a protective block is provided on the other side of the connecting rod. A pressure block is slidably connected to the inner side of the protective block, and a threaded rod is rotatably connected to the top of the pressure block. A threaded hole is provided at the top of the protective block, and the threaded hole and the threaded rod are connected by threads. A pair of slots are provided at the top of the protective block, and a pair of locking blocks are provided at the bottom of the protective block. A reinforcing layer is provided inside the mold steel body. An anti-oxidation layer is provided on one side of the reinforcing layer, and a wear-resistant layer is provided on the outer side of the anti-oxidation layer.

[0008] Furthermore, the bolt and the adjusting hole are matched, and the slot and the locking block are matched.

[0009] Furthermore, rubber pads are provided on the inner sides of the protective block and the pressure block.

[0010] Furthermore, a limiting groove is provided at the top of the threaded rod.

[0011] Furthermore, the reinforcing layer is composed of GM steel and ER5 steel.

[0012] Furthermore, the antioxidant layer is a chromium oxide film.

[0013] Furthermore, the wear-resistant layer is a PVD coating.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. By cooperating with the mounting block, sleeve rod, bolt, connecting rod, adjusting hole, protective block, pressure block, threaded rod, and threaded hole, rotate the sleeve rod along the mounting block to fit the mold steel body. Loosen the bolt, and the connecting rod is limited and installed inside the sleeve rod. Then pull the connecting rod to the appropriate position, tighten the bolt to lock the bolt into the adjusting hole, and achieve a fixing effect. Then, using a tool, align the threaded rod with the limiting groove, rotate the threaded rod to drive the pressure block to move down, which will drive the pressure block to lock the mold steel body, achieving the effect of protecting the edges and corners of the mold steel, avoiding wear on the edges and corners, and indirectly improving the quality of the mold steel body.

[0016] 2. Through the cooperation between the slot and the block, the block and the slot match. When in use, the block is inserted into the slot, which facilitates the stacking of multiple mold steels and avoids shaking, thus indirectly improving safety.

[0017] 3. Through the design of a reinforcing layer, an anti-oxidation layer, and a wear-resistant layer, the reinforcing layer is composed of GM steel and ER5 steel. Through composition optimization and process control, it combines high toughness and high wear resistance. The anti-oxidation layer is a chromium oxide film, which slows down the oxidation of the mold steel body. The wear-resistant layer is a PVD coating with a hardness of 2000-4000 HV, which significantly improves the wear resistance of the mold steel body and extends its service life.
