Description

Technical Field

[0001] This utility model relates to the field of mold steel technology, specifically to a mold steel with wear-resistant properties. Background Technology

[0002] Mold steel is a special type of steel used specifically for manufacturing molds such as cold stamping dies, hot forging dies, and die casting molds. Its performance directly affects the durability of the molds and the processing accuracy of industrial products. It is widely used in industries such as machinery manufacturing, electronics, and automobiles, and is a core tool in processes such as stamping, injection molding, and die casting, directly affecting product accuracy and production costs.

[0003] The prior art patent document with publication number CN222630043U provides a mold steel body, with protective structures provided at each end of the mold steel body. The protective structures include protective plates, mounting grooves, and soft blocks. The mounting grooves are located on the end face of the protective plate facing the mold steel body, and the soft blocks are fixedly disposed within the inner cavity of the mounting grooves. This utility model, through the combined arrangement of protective and connecting structures, provides safe protection for the ends of the mold steel body. This prevents adjacent mold steel bodies from coming into contact with each other during movement, transportation, or stacking, thus avoiding frictional damage caused by collisions. This effectively improves the safety of the mold steel body during movement or placement, and extends its service life. Furthermore, the protective plates are easy to install and remove, highly flexible, and reusable, reducing the cost of safety protection for the mold steel body. The invention also includes a mold steel body with protective structures at each end, comprising protective plates, mounting grooves, and soft blocks. The mounting grooves are located on the end face of the protective plate facing the mold steel body, and the soft blocks are fixedly disposed within the inner cavity of the mounting grooves. This utility model, through the combination of protective and connecting structures, provides safe protection for the ends of the mold steel body. This prevents adjacent mold steel bodies from coming into contact with each other during movement, transportation, or stacking, thus avoiding frictional damage caused by collisions. This effectively improves the safety of the mold steel body during movement or placement, and extends its service life. At the same time, the protective plate is easy to install and remove, highly flexible, and reusable, reducing the cost of safety protection for the mold steel body.

Secondly, the steel body itself has limited protective effect and poor wear resistance. Utility Model Content

[0005] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0006] 1. Technical problems to be solved:

[0007] In order to solve the problems of poor stability and poor wear resistance mentioned above, this utility model is proposed.

[0008] Therefore, the purpose of this utility model is to provide a mold steel with wear resistance, aiming to solve the problem of poor stability as much as possible and achieve better wear resistance performance.

[0009] 2. Technical Solution:

[0010] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0011] A wear-resistant mold steel includes a steel body with multiple fixing components symmetrically distributed on its surface. Each fixing component includes a pad, and a fixing rod is bolted to the top of the pad. The top of the fixing rod has a groove, and a movable rod is slidably connected to the inner wall of the groove. A spring is welded to the bottom of the movable rod, and one end of the spring is welded to the bottom of the inner wall of the groove. A protective component is provided inside the steel body. The groove design allows the movable rod to always move within the groove, thus facilitating better maintenance of the stability of the pad during the fixing process.

[0012] As a preferred embodiment of the wear-resistant mold steel of this utility model, the top of the pad is connected to a slot by bolts, and the bottom of the pad is connected to a block by bolts. The length, width and height of the block match the length, width and height of the inner wall of the slot.

[0013] As a preferred embodiment of the wear-resistant mold steel of this utility model, there are multiple pads, and the pads are symmetrically distributed.

[0014] As a preferred embodiment of the wear-resistant mold steel of this utility model, the protective component includes an oxidation-resistant layer, the material of which is a zinc-plated layer, and an internal wear-resistant layer, the material of which is a nano-coating, wherein the thickness of both the oxidation-resistant layer and the wear-resistant layer is 0.08-0.15 mm.

[0015] As a preferred embodiment of the wear-resistant mold steel of this utility model, the protective component further includes a heat-resistant layer, the heat-resistant layer being a silicon nitride alloy layer, and a crack-resistant layer being provided inside the heat-resistant layer, the crack-resistant layer being a polyurethane alloy layer, the thickness of both the heat-resistant layer and the crack-resistant layer being 0.08-0.15mm.

[0016] As a preferred embodiment of the wear-resistant mold steel of this utility model, the inner wall of the pad is connected to a friction pad by bolts, and the surface of the friction pad is bonded with several friction points.

[0018] 3. Beneficial effects:

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This wear-resistant mold steel has a device with a fixing component. A spring drives the movable rod to move vertically on the inner wall of the fixing rod, which facilitates the installation of the inner wall of the pad on the surface of the steel body. This makes it easy to install and fix steel bodies of various heights. The slot on the top of the pad and the locking block that engages with the slot make it easy to stack the steel bodies, thereby reducing the phenomenon of multiple steel bodies slipping during placement and helping to better maintain the service life of the steel bodies to a certain extent.

[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0029] This utility model is described in detail with reference to the schematic diagrams.

[0032] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0033] This utility model provides an overall structural schematic diagram of an embodiment of a wear-resistant mold steel, including:

[0034] Please see Figures 1-4 This utility model provides a technical solution:

[0035] A wear-resistant mold steel includes a steel body 1. Multiple fixing components 2 are symmetrically distributed on the surface of the steel body 1. Each fixing component 2 includes a pad 23. A fixing rod 29 is bolted to the top of the pad 23. A groove 28 is formed on the top of the fixing rod 29. A movable rod 26 is slidably connected to the inner wall of the groove 28. A spring 27 is welded to the bottom of the movable rod 26. One end of the spring 27 is welded to the bottom of the inner wall of the groove 28. A protective component 3 is provided inside the steel body 1. The tension of the spring 27 facilitates the vertical movement of the movable rod 26 within the inner wall of the groove 28, thereby facilitating the fixing of steel bodies 1 of various heights.

[0036] It is worth noting that, in order to facilitate better stability of the device when it is stacked, the top of the pad 23 is connected to the slot 24 by bolts, and the bottom of the pad 23 is connected to the block 25 by bolts. The length, width and height of the block 25 match the length, width and height of the inner wall of the slot 24. Through the matching length, width and height of the slot 24 and the block 25, as well as the snap-fit ​​structure between them, the device can maintain better stability when it is stacked.

[0037] Next, in order to facilitate the fixing component 2 to achieve a better fixing effect on the surface of the steel body 1, there are multiple pads 23, which are symmetrically distributed. The symmetrical distribution of the pads 23 facilitates the fixing component 2 to achieve a better fixing effect on the surface of the steel body 1.

[0038] Meanwhile, in order to facilitate better oxidation resistance and wear resistance on the surface of the steel body 1, the protective component 3 specifically includes an oxidation-resistant layer 34, which is made of zinc plating. An wear-resistant layer 33 is provided inside the oxidation-resistant layer 34, which is made of nano-coating. The thickness of both the oxidation-resistant layer 34 and the wear-resistant layer 33 is 0.08-0.15mm, preferably 0.15mm. The materials of the oxidation-resistant layer 34 and the wear-resistant layer 33 facilitate better oxidation resistance and wear resistance on the surface of the steel body 1.

[0039] Furthermore, in order to facilitate better crack resistance and heat resistance for the steel body 1 itself, the protective component 3 specifically includes a heat-resistant layer 32. The heat-resistant layer 32 is made of silicon nitride alloy, and a crack-resistant layer 31 is disposed inside the heat-resistant layer 32. The crack-resistant layer 31 is made of polyurethane alloy. The thickness of both the heat-resistant layer 32 and the crack-resistant layer 31 is 0.08-0.15mm, preferably 0.15mm. The materials of the heat-resistant layer 32 and the crack-resistant layer 31 facilitate better crack resistance and heat resistance for the steel body 1 itself.

[0040] It is worth noting that, in order to reduce friction and scratches when accidentally dropped, the inner wall of the pad 23 is connected to a friction pad 22 by bolts. The surface of the friction pad 22 has several friction points. Through the structural design of the pad 23, it is easy to better protect the corners of the steel body 1 and reduce friction and scratches when accidentally dropped.

[0041] Finally, in order to provide better protection for the corners of the steel body 1, an elastic rubber block 21 is set above the friction pad 22. Several friction points are bonded to the surface of the elastic rubber block 21. Through the structural design of the elastic rubber block 21, it is easy to cooperate with the lifting height of the movable rod 26 to provide better protection for the corners of the steel body 1.

[0042] In addition, the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0043] Combination Figures 1-4 The specific usage process of the wear-resistant mold steel of this embodiment is as follows:

[0044] 1: When using this wear-resistant mold steel, after the operator moves the device to a suitable position, the steel body 1 is fixed by the fixing component 2;

[0045] 2: When the steel body 1 has multiple heights, the device is equipped with a fixing component 2. The operator pulls the pad 23 apart, which makes it easier for the spring 27 to be stretched. This causes the spring 27 to drive the movable rod 26 to move vertically inside the fixed rod 29, i.e., inside the groove 28. This makes it easier for the friction pad 22 and the elastic rubber block 21 to be tightly attached to the surface around the steel plate, thus making it easier to fix the steel body 1 of various heights. The snap-fit ​​connection design between the slots 24 of the clip 25 makes it easy to stack the steel body 1, thereby reducing the phenomenon of multiple steel bodies 1 slipping during placement and, to a certain extent, helping to better maintain the service life of the steel body 1.

[0046] 3: When the steel body 1 needs to have good wear resistance, the device is equipped with a protective component 3. The oxidation-resistant layer 34, i.e., the zinc plating layer, helps to reduce the coefficient of friction, reduce the contact between oxygen and moisture, and extend the service life. The wear-resistant layer 33, i.e., the nano-coating, helps to enhance the wear resistance of the surface of the steel body 1. The heat-resistant layer 32, i.e., the silicon nitride alloy layer, helps the mold steel body to have heat resistance and high temperature resistance. The crack-resistant layer 31, i.e., the polyurethane alloy layer, helps the mold steel body to have crack resistance and minimizes the possibility of the mold steel body breaking. Through the cooperation between the crack-resistant layer 31, the heat-resistant layer 32, the wear-resistant layer 33, and the oxidation-resistant layer 34, a good protective effect is achieved for the steel body 1.

[0047] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
