Description

Technical Field

[0001] The present application relates to the technical field of mold steel protection, and in particular to a corrosion-resistant mold steel. Background Art

[0002] Mold steel is a type of steel used to manufacture molds such as cold stamping molds, hot forging molds, and die-casting molds. Mold steel is generally in the form of sheets or bars. Before processing, mold steel has always been stacked on the ground. However, stacking can easily cause surface friction or rust damage to the mold steel, leading to pitting corrosion. Pitting corrosion is a form of corrosion damage that occurs in local areas of the metal surface. After pitting is formed, it will rapidly develop to a very deep depth and finally penetrate into the mold steel, causing greater damage. Therefore, mold steel needs to be protected to a certain extent.

[0003] Most current mold steels are protected against corrosion by coating or adding composite structures, or by installing some isolation structures on the outside of the mold steel. For example, Chinese patent publication number CN220578693U discloses a corrosion-resistant mold steel comprising a mold steel column with a hoisting mechanism provided on the outer circumference of each end of the mold steel column. The hoisting mechanism comprises a fixed sleeve mounted on the outer circumference of the mold steel column, a plurality of equally spaced sliding grooves formed on one side of the fixed sleeve, a clamping block slidably connected within the sliding grooves and capable of synchronously moving toward the center of the fixed sleeve, and the clamping block is slidably connected to the outer circumference of the mold steel column. The fixed sleeve is mounted on both ends of the mold steel column, and the adjustment grooves on the fixed shaft are turned by a tool, thereby rotating the fixed shaft. The driving gear drives the gear ring and the rotating ring to rotate, and the guide thread on the rotating ring engages with the rack on the clamping block, driving the clamping block to move along the sliding groove to clamp the mold steel column. The lifting threaded holes on the fixed sleeve can be used to install lifting rings, which are connected to external lifting equipment for lifting.

[0004] In the above, by setting a lifting mechanism on the outer peripheral surfaces of both ends of the mold steel, the mold steel can be isolated and it is convenient to install. Regarding the related technology mentioned above, the inventor believes that although the application can fix the mold steel, its structure is complicated to operate and inconvenient to use. Therefore, it is necessary to design a corrosion-resistant mold steel that is easy to use. Utility Model Content

[0014] 1. This application provides a protective effect on the mold steel body by setting a sleeve at both ends of the mold steel body, thereby preventing the mold steel body from being damaged by collision and friction between the mold steel bodies; by setting a retractable fixing part in the center of the sleeve, and at the same time providing multiple fixing rings of different diameters in the fixing part, it can adapt to mold steel bodies of different sizes and facilitate installation and connection. At the same time, the fixing ring can be sleeved on the outside of the mold steel body to support and fix the mold steel body, thereby preventing the mold steel body from being corroded and damaged.

[0015] 2. By setting the sleeve to a polygon and providing rounded corners at the edges and corners of the sleeve, the position or angle of the sleeve can be fixed, the movement of the mold steel body can be avoided, and the mold steel body can be stably placed; by setting the fixing part to a tower-shaped structure, it is convenient to embed fixing rings of different diameters inside it, and the fixing rings can be connected through the fixing part for easy extension and retraction; by providing an arc-shaped convex part at the end of the fixing part and providing an air hole on the arc-shaped convex part, the sleeve can be prevented from being adsorbed on the mold steel body, which is convenient for installation and removal; by providing a reinforcement ring in the sleeve and the reinforcement ring is concentrically arranged with the fixing ring, combined with the ribs arranged between the sleeve and the reinforcement ring, the strength of the sleeve can be enhanced, which is convenient for accommodating the fixing ring.

[0019] The present application is further described in detail below with reference to the accompanying drawings.

[0020] The embodiments of the present application disclose a corrosion-resistant die steel.

[0021] Reference Figure 1 and Figure 2 A corrosion-resistant mold steel includes a mold steel body 1 and a sleeve 2. The mold steel body 1 is cylindrical, the outer side of the sleeve 2 is polygonal, and the corners of the sleeve 2 are rounded. The sleeve 2 in this example is hexagonal, and a retractable fixing part 201 is provided in the center of the sleeve 2. A plurality of fixing rings 202 of different diameters are concentrically provided in the fixing part 201. The fixing ring 202 can be sleeved on the outer side of the mold steel body 1. Specifically, in this example, the sleeve 2 is made of rubber material, and the fixing part 201 is a tower-shaped structure made of vulcanized rubber material. The fixing part 201 is connected to the fixing ring 202. The fixing ring 202 is a steel ring and is embedded in the interior of the fixing part 201. The inner side of the fixing portion 201 has a rounded corner or chamfer at a position corresponding to the end of the fixing ring 202; adjacent fixing rings 202 are connected through the fixing portion 201. Specifically, the end of the fixing portion 201 in this example is provided with an arc-shaped convex portion and the arc-shaped convex portion is provided with an air vent 201a. The setting of the air vent 201a can prevent the sleeve 2 from being adsorbed on the end of the mold steel body 1, which is convenient for installation and removal; a reinforcement ring 203 is provided at the center of the sleeve 2 and the reinforcement ring 203 is connected to the fixing portion 201. The reinforcement ring 203 is concentrically arranged with the fixing ring 202, and a number of ribs 204 are provided between the sleeve 2 and the reinforcement ring 203, which can enhance the strength of the sleeve 2 and facilitate the storage of the fixing ring 202.

[0022] Specific implementation method: When using this application, the staff only needs to lift the cylindrical mold steel body 1 and then insert the sheath 2 into both ends of the mold steel body 1. Since a fixing part 201 is provided in the sheath 2 and a plurality of fixing rings 202 of different diameters are provided in the fixing part 201, the fixing ring 202 can be passed through the two ends of the mold steel body 1 for fixing, thereby preventing the mold steel body 1 from directly contacting the ground or colliding with the adjacent mold steel body 1 and being damaged, thereby avoiding pitting corrosion of the mold steel and ensuring the service life of the mold steel.
