Description

Technical Field

[0001] This utility model relates to the field of aluminum casting molds, and in particular to an aluminum casting mold structure that facilitates the replacement of easily damaged parts. Background Technology

[0002] During the use of aluminum casting molds, some areas of the mold core are prone to damage. In order to reduce maintenance costs, the easily damaged areas are made into separate wear parts. Only the wear parts need to be replaced, which is relatively inexpensive.

[0003] The vulnerable parts are small in size and can be fixed in the mold core by interference fit. Moreover, during use, the force on the vulnerable parts is directed towards the mold core, so there is basically no problem of them falling off. However, disassembly is difficult. Often, the entire cast aluminum mold needs to be disassembled before the vulnerable parts can be replaced, which is time-consuming and labor-intensive and needs to be improved. Utility Model Content

[0004] The main technical problem solved by this utility model is to provide a cast aluminum mold structure that facilitates the replacement of vulnerable parts, making it easier to install, disassemble and replace vulnerable parts, and improving the ease of operation.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: providing a cast aluminum mold structure that facilitates the replacement of vulnerable parts, comprising: a template, a mold core, vulnerable parts, a push rod, a valve stem, and a valve block. The mold core is disposed at the bottom of the template, and the bottom of the mold core is recessed with an embedding groove corresponding to the vulnerable parts. The vulnerable parts are disposed in the embedding groove and are interference-fitted. The mold core is provided with a through hole extending upward from the embedding groove. The push rod is disposed in the through hole and extends upward into the template. The valve block is laterally suspended above the push rod. The valve stem is disposed on the back of the valve block and extends to the outside of the template. The top surface of the template is recessed with a guide groove corresponding to the valve stem. The bottom of the valve block is provided with an inclined surface that slides in contact with the top of the push rod.

[0006] In a preferred embodiment of this utility model, the bottom of the vulnerable part is provided with a cast aluminum forming part.

[0007] In a preferred embodiment of this utility model, the template is provided with a guide hole corresponding to the top rod.

[0008] In a preferred embodiment of this utility model, the inclined surface extends downward in the direction of the valve stem.

[0009] In a preferred embodiment of the present invention, a limit block is provided at the top of the valve stem, and a first stop block located in front of the limit block and a second stop block located behind the limit block are provided on the guide groove.

[0010] In a preferred embodiment of this utility model, the valve stem, the limiting block, and the valve block adopt an integrated structure.

[0011] In a preferred embodiment of this utility model, the bottom of the top rod is integrally provided with a top post that contacts the top of the vulnerable part, and the outer diameter of the top post is larger than the outer diameter of the top rod.

[0012] In a preferred embodiment of this utility model, a guide sleeve corresponding to the push rod is provided in the through hole. The guide sleeve is concentrically arranged on the outside of the push rod and located above the push column. A limit ring is integrally provided on the top of the outer circle of the guide sleeve, and an annular groove corresponding to the limit ring is provided on the top of the through hole.

[0013] In a preferred embodiment of this utility model, the tail of the valve stem is provided with a mounting hole located on the outside of the template.

[0014] The beneficial effects of this utility model are as follows: This utility model provides a cast aluminum mold structure that facilitates the replacement of vulnerable parts.

[0020] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Please see Figures 1-4 The embodiments of this utility model include:

[0022] like Figures 1-4 The aluminum casting mold structure shown is convenient for replacing vulnerable parts, including: template 1, mold core 11, vulnerable parts 13, ejector rod 9, valve rod 2 and valve block 3. The mold core 11 is set at the bottom of the template 1. The bottom of the template 1 is recessed and has a positioning groove corresponding to the mold core 11. It is easy to assemble and the mold core 11 can be fixed with screws. The structure is solid.

[0023] An insert groove 15 corresponding to the vulnerable part 13 is recessed at the bottom of the mold core 11. The vulnerable part 13 is placed in the insert groove 15 with an interference fit, which makes the installation of the vulnerable part 13 convenient and the structure stable. Moreover, during the use of the aluminum casting mold, the vulnerable part 13 is subjected to force in the direction of the mold core 11 and will not fall off automatically. A cast aluminum forming part 14 is provided at the bottom of the vulnerable part 13. The cast aluminum forming part 14 mates with the bottom surface of the mold core 11 to form the cast aluminum part.

[0024] A through hole 20 extending upward from the embedding groove 15 is provided in the mold core 11. The push rod 9 is provided in the through hole 20 and extends upward into the template 1. In this embodiment, the template 1 is provided with a guide hole 12 corresponding to the push rod 9, which does not affect the lifting and lowering action of the push rod 9.

[0025] like Figure 3 As shown, the bottom of the top rod 9 is integrally provided with a top post 19 that contacts the top of the vulnerable part 13. The outer diameter of the top post 19 is larger than the outer diameter of the top rod 9, forming a step to ensure the contact area with the top of the vulnerable part 13.

[0026] A guide sleeve 16 corresponding to the push rod 9 is provided in the through hole 20. The guide sleeve 16 is concentrically arranged on the outside of the push rod 9 and above the push column 19 to guide the push rod 9 and limit the push column 19, thereby limiting the vulnerable part 13, avoiding the problem of the vulnerable part 13 moving upward, and improving the position progress of the vulnerable part 13.

[0027] A limiting ring 17 is integrally provided on the top of the outer circle of the guide sleeve 16, and an annular groove 18 corresponding to the limiting ring 17 is provided on the top of the through hole 20 to perform axial positioning of the guide sleeve 16. In addition, the pressing of the template 1 improves the axial stability of the guide sleeve 16.

[0028] The valve block 3 is horizontally suspended above the top rod 9. The valve rod 2 is located on the back of the valve block 3 and extends to the outside of the template 1. The top surface of the template 1 is recessed with a guide groove 7 corresponding to the valve rod 2 to guide the horizontal movement of the valve rod 2. The tail of the valve rod 2 is provided with a mounting hole 8 located on the outside of the template 1 for easy connection with a cylinder. The horizontal movement of the valve rod 2 is driven by manual tapping or a cylinder.

[0029] like Figure 2 As shown, the bottom of the valve block 3 is provided with an inclined surface 10 that slides in contact with the top of the push rod 9. In this embodiment, the inclined surface 10 extends obliquely downward in the direction of the valve rod 2. When the valve rod 2 drives the valve block 3 to move to the right, the inclined surface 10 cooperates with the top of the push rod 9, driving the push rod 9 to move downward and pushing the vulnerable part 13 downward out of the embedded groove 15. This makes disassembly convenient and facilitates the replacement of the vulnerable part 13.

[0030] like Figure 4 As shown, a limit block 4 is integrally installed at the top of the valve stem 2. A first stop 6 is located in front of the limit block 4, and a second stop 5 is located behind the limit block 4 on the guide groove 7. The first stop 6 and the second stop 5 limit the forward and backward movement of the limit block 4, preventing the valve stem 2 from disengaging from the guide groove 7. The first stop 6 and the second stop 5 are fixed with screws, making disassembly and assembly convenient.

[0031] In addition, the valve stem 2, the limit block 4 and the valve block 3 adopt an integrated structure, which can be made of integrated steel structure, with high strength, good impact resistance and not easy to bend or deform.

[0032] In summary, the aluminum mold structure disclosed in this utility model facilitates the replacement of vulnerable parts, making it convenient for the installation, disassembly, and replacement of vulnerable parts. The structure is simple, and the template does not need to be disassembled during the replacement of vulnerable parts, making the operation quick.

[0033] The above are merely embodiments of this utility model and do 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, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
