Description

Technical Field

[0001] This utility model relates to the field of cast steel mold technology, and in particular to a cast steel mold splicing structure. Background Technology

[0002] As the core equipment for forming steel products, the working principle of cast steel molds is to inject molten steel into the cavity formed by the upper and lower mold bases. After the molten steel cools and solidifies, the mold is disassembled to obtain steel products that conform to the design shape and specifications. The cavity accuracy and structural stability of the upper and lower mold bases directly determine the dimensional tolerances, surface quality and forming consistency of the castings, and are key components to ensure product quality in cast steel production.

[0003] Many existing cast steel molds have internal cavities that are machined as a single piece. However, some internal cavities have complex structures and are difficult to machine. If a part of the integral mold base is damaged, the damaged part cannot be replaced individually because the components cannot be disassembled. The entire mold base must be scrapped and replaced, which not only wastes a lot of steel resources but also increases the maintenance cost of the mold.

[0004] Therefore, it is necessary to provide a new splicing structure for cast steel molds to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a new splicing structure for cast steel molds.

[0006] The cast steel mold splicing structure provided by this utility model includes: an upper mold base and a lower mold base. The lower mold base includes a base, on which a U-shaped mounting groove is provided. A square mounting plate is fixedly installed in the middle of the U-shaped mounting groove. Two symmetrically distributed U-shaped templates are inserted into the U-shaped mounting groove. An inner bottom mold is detachably installed on the square mounting plate.

[0007] Both of the two U-shaped templates have U-shaped slots at their close ends. The base is equipped with a docking structure, which includes a U-shaped plate that is inverted on the U-shaped slot. The four side walls of the inner bottom mold are fitted to the U-shaped template and the U-shaped plate. A connecting plate is fixedly installed at the end of the U-shaped plate, and the connecting plate is detachably connected to the base by connecting bolts.

[0008] The base is also equipped with a stabilizing structure, which includes a top plate that fits against the outer wall of the U-shaped template.

[0009] Preferably, the square mounting plate is integrally formed with the base, and the square mounting plate has a positioning hole that penetrates the base. A positioning post fixed to the bottom of the inner bottom mold is inserted into the positioning hole, and a fixing bolt that abuts against the lower side wall of the base is threaded onto the positioning post.

[0010] Preferably, the lower sidewall edges of the inner bottom mold are all chamfered.

[0011] Preferably, the two U-shaped templates are fitted with a gap, and the U-shaped card plate abuts against the side wall of the U-shaped card slot.

[0012] Preferably, a reinforcing rib is fixedly installed on the connecting plate, and the reinforcing rib is fixedly connected to the U-shaped clamping plate.

[0013] Preferably, the lower edge of the inner wall of the U-shaped card plate is chamfered.

[0014] Preferably, the stabilizing structure further includes a connecting block fixedly installed on the base, an internally threaded cylinder fixedly installed on the side wall of the top plate, an adjusting bolt rotatably connected to the connecting block, and the end of the adjusting bolt is inserted into the internally threaded cylinder and threadedly connected to it.

[0015] Preferably, a limiting plate is fixedly installed on the connecting block, and the limiting plate is used to limit the offset of the top plate.

[0016] Compared with related technologies, the cast steel mold splicing structure provided by this utility model has the following beneficial effects:

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0027] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0028] Please see Figures 1 to 5 The present invention provides a steel mold splicing structure, which includes an upper mold base 1 and a lower mold base 2. The lower mold base 2 includes a base 21, on which a U-shaped mounting groove 211 is provided, and a square mounting plate 212 is fixedly installed in the middle of the U-shaped mounting groove 211. Two symmetrically distributed U-shaped templates 22 are inserted into the U-shaped mounting groove 211, and an inner bottom mold 23 is detachably installed on the square mounting plate 212.

[0029] It should be noted that: In this utility model, the two U-shaped templates 22 and the inner bottom mold 23 are installed on the base 21 to form a basic lower mold base 2, which is detachable. This reduces the processing difficulty of the lower mold base 2 and facilitates the replacement of damaged parts of the lower mold base 2, avoiding the waste of replacing the entire lower mold base 2. It is suitable for molds with relatively complex internal cavities. When there are residues on the inner bottom corners of the mold that are difficult to clean, the lower mold base 2 can be disassembled to clean the residual impurities. The U-shaped mounting groove 211 opened on the base 21 is used for the installation and positioning of the two U-shaped templates 22, reducing the assembly difficulty. The square mounting plate 212 serves as the installation base for the inner bottom mold 23, ensuring the relative positional accuracy between the inner bottom mold 23 and the U-shaped template 22, thereby ensuring the accuracy of the casting forming dimensions.

[0030] It is worth noting that: the square mounting plate 212 is integrally formed with the base 21, and the square mounting plate 212 has a positioning hole 213 penetrating the base 21. A positioning post 231 fixed to the bottom of the inner bottom mold 23 is inserted into the positioning hole 213. A fixing bolt 232 that abuts against the lower side wall of the base 21 is threaded onto the positioning post 231. The base 21 and the square mounting plate 212 adopt an integral forming process (such as integral casting followed by milling), which completely eliminates the reference deviation that may exist in traditional split installation, and greatly improves the load-bearing stability and positional accuracy of the square mounting plate 212. At the same time, the square mounting plate 212 has a positioning hole 213 penetrating the base 21. Positioning hole 213 is used to precisely mate with positioning pin 231 of inner bottom mold 23. During assembly, positioning pin 231 is vertically inserted into positioning hole 213. Positioning pin 231 has a threaded hole inside. After positioning pin 231 is inserted into positioning hole 213, fixing bolt 232 is inserted from the underside of base 21 and threadedly connected to positioning pin 231 until the bolt head is tightly abutted against the lower side wall of base 21. The axial locking force of fixing bolt 232 firmly fixes inner bottom mold 23 onto square mounting plate 212, while preventing inner bottom mold 23 from shifting upward due to molten metal impact during casting. This makes inner bottom mold 23 detachable, easy to assemble, and easy to replace when damaged.

[0031] The lower sidewall edge of the inner bottom mold 23 is chamfered. After the two U-shaped templates 22 are inserted into the U-shaped mounting groove 211, they are pre-limited by the external structure. Then, the inner bottom mold 23 is inserted from the middle of the two U-shaped templates 22 and connected and fixed to the base 21. The two U-shaped templates 22 are then fixed and limited. The bottom edge of the inner bottom mold 23 is chamfered to facilitate its embedding between the two U-shaped templates 22.

[0032] In the embodiments of this utility model, please refer to Figures 1 to 6 Both U-shaped templates 22 have U-shaped slots 221 at their close ends. A docking structure 3 is mounted on the base 21. The docking structure 3 includes a U-shaped plate 31 that is inverted on the U-shaped slot 221. The four side walls of the inner bottom mold 23 are fitted to the U-shaped template 22 and the U-shaped plate 31. A connecting plate 32 is fixedly installed at the end of the U-shaped plate 31. The connecting plate 32 is detachably connected to the base 21 by connecting bolts 33.

[0033] It should be noted that after the two U-shaped templates 22 are symmetrically assembled in the U-shaped mounting groove 211, the U-shaped slots 221 at their ends need to be aligned and spliced. At this time, the mating structure 3 achieves precise fixation of the template through "inverted locking". First, the U-shaped clamping plate 31 is inverted and placed on the aligned U-shaped slot 221. The tight fit between the U-shaped clamping plate 31 and the U-shaped slot 221 restricts the vertical displacement of the U-shaped template 22 (to prevent the U-shaped template 22 from shaking due to assembly deviation). Then, the connecting plate 32 is locked to the base 21 by the connecting bolts 33. The axial tension of the connecting bolts 33 keeps the U-shaped clamping plate 321 in place. 1. Applying downward pressure to the U-shaped template 22, firmly fixing the U-shaped template 22 within the return-shaped mounting groove 211, preventing the U-shaped template 22 from shifting in the vertical direction (the direction of the molten metal impact during casting); at the same time, the four side walls of the inner bottom mold 23 form a corresponding and fitted assembly with the U-shaped template 22 and the U-shaped clamping plate 31, and the side walls of the inner bottom mold 23 fit together with the inner side walls of the U-shaped template 22 and the side walls of the U-shaped clamping plate 31 located inside the U-shaped template 22, ensuring that there are no gaps on the sides of the cavity, preventing molten metal from seeping into the gaps and forming flash, improving the casting quality, and facilitating the assembly and disassembly of the U-shaped template 22.

[0034] It is worth noting that the two U-shaped templates 22 are fitted with a gap, and the U-shaped clamping plate 31 abuts against the side wall of the U-shaped groove 221. The reserved gap reduces the processing accuracy requirements of the U-shaped template 22 and reduces the processing cost of the U-shaped template 22. At the same time, the abutment between the U-shaped clamping plate 31 and the side wall of the U-shaped groove 221 can improve the assembly tolerance, reduce the assembly difficulty, and improve the production efficiency.

[0035] Among them, a reinforcing rib 34 is fixedly installed on the connecting plate 32, and the reinforcing rib 34 is fixedly connected to the U-shaped clamping plate 31; thereby improving the connection between the U-shaped clamping plate 31 and the connecting plate 32 and improving the constraint stability of the docking structure 3 on the two U-shaped templates 22.

[0036] The lower edge of the inner wall of the U-shaped card plate 31 is chamfered to facilitate the insertion of the U-shaped card plate 31 into the U-shaped slot 221 on the U-shaped template 22, thus reducing the assembly difficulty.

[0037] In the embodiments of this utility model, please refer to Figure 1 and Figure 7 The base 21 is also equipped with a stabilizing structure 4. The stabilizing structure 4 includes a top plate 42 that fits against the outer wall of the U-shaped template 22. The stabilizing structure 4 also includes a connecting block 41 that is fixedly installed on the base 21. An internal threaded cylinder 43 is fixedly installed on the side wall of the top plate 42. An adjusting bolt 44 is rotatably connected to the connecting block 41, and the end of the adjusting bolt 44 is inserted into the internal threaded cylinder 43 and threadedly connected to it.

[0038] It should be noted that the connecting block 41 can be fixed to the base 21 with bolts. When the docking structure 3 performs the initial assembly of the two U-shaped templates 22 and inserts them into the inner bottom mold 23 for fixation, the adjusting bolt 44 can be rotated by wrench or power tool to move the threaded cylinder 43 connected to the adjusting bolt 44 toward the U-shaped template 22, so that the two U-shaped templates 22 are close to each other and tightly attached to the inner bottom mold 23, providing lateral support for the U-shaped template 22 and ensuring that the U-shaped template 22 is tightly attached to the inner bottom mold 23. The stabilizing structure 4 maintains the positional accuracy of the U-shaped template 22 to ensure the tightness of the fit between the inner side wall of the U-shaped template 22 and the side wall of the inner bottom mold 23. If the U-shaped template 22 is laterally displaced, it may cause gaps between the inner bottom mold 23 and the U-shaped template 22, and molten metal may easily seep in and form flash. The lateral support of the stabilizing structure 4 prevents the U-shaped template 22 from displacing, indirectly ensuring the tight fit between the inner bottom mold 23 and the U-shaped template 22, reducing the generation of flash, and improving the overall stability of the lower mold base 2 in conjunction with the docking structure 3.

[0039] Among them, a limiting plate 45 is fixedly installed on the connecting block 41, and the limiting plate 45 is used to limit the offset of the top plate 42. The limiting plate 45 restricts the top plate 42 to prevent the top plate 42 from being offset when the adjusting bolt 44 is turned, so that the top plate 42 can only be displaced in the direction toward the U-shaped template 22.

[0040] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
