Description

A high-temperature resistant and high-strength mold steel Technical Field

[0001] This utility model relates to the field of mold steel technology, specifically a high-temperature resistant and high-strength mold steel. Background Technology

[0002] In manufacturing, molds serve as core tools in industrial production and are widely used in numerous fields such as automobiles, aerospace, electronics, and home appliances. The performance and quality of molds directly determine the production efficiency, precision, and lifespan of products.

[0003] A search revealed a utility model patent with Chinese patent publication number CN222347716U, which discloses a high-temperature resistant and high-strength mold steel. The mold steel body includes a mold steel body and four sets of protective support blocks for supporting the four corners of the mold steel body. Each protective support block is cubic in shape and has a placement recess with an anti-slip buffer pad. The top of each protective support block has a positioning post, and the bottom of each protective support block has a positioning hole that cooperates with the positioning post.

[0004] The aforementioned device supports the mold steel using protective support blocks; however, it lacks limiting mechanisms during use, so it may detach if it shakes during transport, posing a certain safety hazard. Summary of the Invention

[0005] The purpose of this invention is to provide a high-temperature resistant and high-strength mold steel to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature resistant and high-strength mold steel, comprising a mold steel body one and a mold steel body two, which are arranged opposite to each other. Two support components are installed between the mold steel body one and the mold steel body two, respectively located on both sides of the mold steel body one. Each support component includes two protective plates sleeved on the outside of the mold steel body one and the mold steel body two. A horizontally arranged partition is provided inside each of the two protective plates. The two partitions are located between the mold steel body one and the mold steel body two. The same connecting component is installed on the two protective plates on the same side. The connecting component includes a hinge seat fixedly connected to the bottom of the outer wall of one of the protective plates. A lead screw two is hinged inside the hinge seat. A movable ring is threaded onto the outside of the lead screw two. A limit sleeve is fixedly connected to the bottom of the outer wall of the other protective plate. The movable ring is inside the limit sleeve, and the width of the knob end of the movable ring is greater than the width of the groove of the limit sleeve.

[0007] Two support components can be connected as a whole, allowing them to mutually restrict and leverage each other. This ensures that the support components function effectively without detaching due to shaking. Place the mold steel body one into the gap between the two support components, then drive the movable end of the lead screw two to rotate along the hinge seat. Subsequently, the movable end of the lead screw two will enter the interior of the limiting sleeve. Then, rotate the moving ring outside the lead screw two. The end of the moving ring will be inserted into the limiting sleeve along the lead screw two, and its knob end will also fit against the outer wall of the limiting sleeve. If one support component tends to detach, the other support component will restrict it through the lead screw two and the moving ring, effectively preventing it from detaching.

[0008] As a further preferred embodiment of this technical solution, one of the protective plates has a mounting base fixedly connected to one end of its outer wall, and a lead screw is rotatably connected inside the mounting base; the other protective plate has a horizontally arranged threaded pipe fixedly connected to one end of its outer wall, and the lead screw is threaded inside the threaded pipe; and the two protective plates are fixedly connected to the same horizontally arranged telescopic rod.

[0009] Adjust the spacing between the two protective plates of the support assembly according to the size of the main body of the mold steel. The lead screw is adapted to the threaded pipe, and the handle drives the lead screw to rotate inside the mounting base. The lead screw will be screwed into the threaded pipe. With the cooperation of the telescopic rod, the protective plate connected to the lead screw will be driven by the lead screw to move closer to the other protective plate on the opposite side, which helps to improve the adaptability of the structure.

[0010] As a further preferred embodiment of this technical solution, guide edges are provided at the top and bottom edges of the protective plate.

[0011] As a further preferred embodiment of this technical solution, nano-tungsten carbide powder is added inside both the mold steel body one and the mold steel body two.

[0012] As a further preferred embodiment of this technical solution, titanium-aluminum based intermetallic compounds are added to the interior of both the mold steel body one and the mold steel body two.

[0013] As a further preferred embodiment of this technical solution, the surfaces of the mold steel body one and the mold steel body two are coated with an alumina ceramic coating.

[0014] As a further preferred embodiment of this technical solution, the thread helix angle of the external threads of the lead screw one and lead screw two is less than the equivalent friction angle.

[0015] This utility model provides a high-temperature resistant and high-strength mold steel, which has the following beneficial effects:

[0016] (1) By setting a connecting component, the two support components can be connected into a whole, so that the two can restrict each other and leverage each other, ensuring that the support components can play their role while not being separated due to shaking. Place the mold steel body one into the gap between the two support components, then drive the movable end of the screw two to rotate along the hinge seat. Then the movable end of the screw two will enter the inside of the limiting sleeve. Then rotate the moving ring outside the screw two. The end of the moving ring will be inserted into the limiting sleeve along the screw two. Its knob end will also fit against the outer wall of the limiting sleeve. If one support component has a tendency to separate, the other support component will restrict it through the screw two and the moving ring, effectively preventing it from separating.

[0017] (2) By setting up a support assembly, the distance between the two protective plates of the support assembly is adjusted according to the size of the mold steel body. The screw rod is adapted to the threaded pipe, and the handle drives the screw rod to rotate inside the mounting seat. The screw rod will be screwed into the threaded pipe. The protective plate connected to the screw rod will be driven by the screw rod to move closer to the other protective plate on the opposite side with the cooperation of the telescopic rod, which is conducive to improving the adaptability of the structure.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] This utility model provides a technical solution: As shown in Figures 1, 2, and 4, in this embodiment, a high-temperature resistant and high-strength mold steel includes a mold steel body 1 and a mold steel body 2, which are arranged opposite to each other. Two support components 5 are installed between the mold steel body 1 and the mold steel body 2, respectively located on both sides of the mold steel body 1. Each support component 5 includes two protective plates 505 sleeved on the outside of the mold steel body 1 and the mold steel body 2, and each of the two protective plates 505 has a horizontally arranged partition inside. Plate 3, both partition plates 3 are located between mold steel body 1 and mold steel body 2. The two protective plates 505 on the same side are equipped with the same connecting component 6. The connecting component 6 includes a hinge seat 601 fixedly connected to the bottom of the outer wall of one of the protective plates 505. A screw rod 602 is hinged inside the hinge seat 601. A moving ring 604 is threaded on the outside of the screw rod 602. A limit sleeve 603 is fixedly connected to the bottom of the outer wall of the other protective plate 505. The moving ring 604 is inside the limit sleeve 603, and the width of the knob end of the moving ring 604 is greater than the width of the groove of the limit sleeve 603.

[0025] Place the mold steel body 1 into the gap between the two support components 5, then drive the movable end of the lead screw 602 to rotate along the hinge 601. Subsequently, the movable end of the lead screw 602 will enter the interior of the limiting sleeve 603. Then, rotate the moving ring 604 outside the lead screw 602. The end of the moving ring 604 will be inserted into the limiting sleeve 603 along the lead screw 602, and its knob end will also fit against the outer wall of the limiting sleeve 603. If one support component 5 tends to detach, the other support component 5 will restrict it through the lead screw 602 and the moving ring 604, effectively preventing it from detaching.

[0026] As shown in Figures 2 and 3, one of the protective plates 505 has a mounting base 503 fixedly connected to one end of its outer wall, and a lead screw 502 is rotatably connected inside the mounting base 503. The other protective plate 505 has a horizontally arranged threaded pipe 501 fixedly connected to one end of its outer wall, and the lead screw 502 is threadedly connected inside the threaded pipe 501. The two protective plates 505 are fixedly connected to the same horizontally arranged telescopic rod 504.

[0027] Adjust the spacing between the two protective plates 505 of the support assembly 5 according to the size of the main body of the mold steel 1. The lead screw 502 is adapted to the threaded tube 501. Drive the handle to rotate the lead screw 502 inside the mounting base 503. The lead screw 502 will be screwed into the threaded tube 501. With the cooperation of the telescopic rod 504, the protective plate 505 connected to the lead screw 502 will be driven by the lead screw 502 to move closer to the other protective plate 505 on the opposite side, which is beneficial to improving the adaptability of the structure.

[0028] As shown in Figure 2, guide edges 4 are provided at the top and bottom edges of the protective plate 505, making it convenient to place the mold steel body 1 and the mold steel body 2.

[0029] As shown in Figure 1, nano-tungsten carbide powder is added to the interior of both mold steel body 1 and mold steel body 2. Nano-tungsten carbide has extremely high hardness, which can refine the grains of the mold steel, hinder grain boundary migration and dislocation movement, thereby improving the strength, hardness, and wear resistance of the mold steel. At high temperatures, the nano-carbide particles can also act as pinning agents, inhibiting the high-temperature softening of the mold steel.

[0030] As shown in Figure 1, titanium-aluminum based intermetallic compounds are added to the interior of both mold steel body 1 and mold steel body 2. These compounds possess high melting points, low density, excellent high-temperature strength, and oxidation resistance. Under high-temperature conditions, the interatomic metallic and covalent bonds work together to give the material high bonding strength and resistance to deformation. Simultaneously, its excellent oxidation resistance protects the mold steel surface from oxidation, thereby improving the strength, hardness, and service life of the mold steel at high temperatures. (The process involves ball milling steel powder, the intermetallic compound, and nanomaterial powder in a high-energy ball mill for an extended period, allowing the two powders to fully mix and undergo a mechanical alloying reaction to form a uniform composite powder. This composite powder is then processed through pressing, sintering, and other techniques to produce a composite material.)

[0031] As shown in Figure 1, the surfaces of mold steel body 1 and mold steel body 2 are coated with an alumina ceramic coating. Alumina is sprayed onto the steel surface using thermal spraying technology to form a ceramic coating. Under high-temperature environments, the ceramic layer effectively blocks oxidizing media such as oxygen and water vapor from contacting the steel substrate, thus protecting the steel from oxidation. Simultaneously, the high hardness of the ceramic material enhances the wear resistance of the steel surface, and the interfacial bonding between the ceramic and steel plays a role in stress transfer and dispersion, improving the overall strength of the steel.

[0032] As shown in Figure 2, the thread helix angle of the external threads of lead screw 1 502 and lead screw 2 602 is less than the equivalent friction angle, which gives them self-locking properties.

[0033] This utility model provides a high-temperature resistant, high-strength mold steel, the specific working principle of which is as follows:

[0034] When the device is working, the distance between the two protective plates 505 of the support assembly 5 is adjusted according to the size of the mold steel body 1. The lead screw 502 is adapted to the threaded tube 501, and the handle drives the lead screw 502 to rotate inside the mounting base 503. The lead screw 502 will be screwed into the threaded tube 501. With the cooperation of the telescopic rod 504, the protective plate 505 connected to the lead screw 502 will be driven by the lead screw 502 to move closer to the other protective plate 505 on the opposite side, which helps to improve the adaptability of the structure. The mold steel body 1 is placed between the two support assemblies 5. In the gap, the movable end of the second lead screw 602 is then driven to rotate along the hinge seat 601. Subsequently, the movable end of the second lead screw 602 will enter the interior of the limiting sleeve 603. Then, the moving ring 604 is rotated outside the second lead screw 602. The end of the moving ring 604 will be inserted into the limiting sleeve 603 along the second lead screw 602, and its knob end will also fit against the outer wall of the limiting sleeve 603. If one support component 5 has a tendency to detach, the other support component 5 will be restricted by the second lead screw 602 and the moving ring 604, effectively preventing it from detaching.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
