Description

Technical Field

[0001] This application relates to the field of mold technology, and in particular to a cylinder end cap die-casting mold. Background Technology

[0002] Molds are tools used in industrial production to manufacture parts or products through molding methods such as injection molding, blow molding, extrusion, stamping, and die casting. They are key process equipment for achieving machining with minimal or no cutting.

[0003] Commonly used in the mass production of aluminum alloy cylinder end caps, molten metal is pressed into the mold cavity under high pressure to form complex structures (such as mounting holes, sealing grooves, reinforcing ribs, etc.) in one step. However, during the forming process, some air will be present in the mold. If the air cannot be expelled in time, it will easily lead to problems with the quality of the formed product and directly affect production efficiency. Utility Model Content

[0005] A cylinder end cap die casting mold includes an openable first module and a second module, wherein the first module and the second module form at least one molding cavity that matches the cylinder end cap.

[0006] The first module is provided with a casting port for the medium to enter, and the casting port is connected to the flow channel of the molding cavity;

[0007] The first module and / or the second module are provided with a plurality of buffer structures arranged around the molding cavity. The buffer structures are connected to the outside and the molding cavity, and are used to discharge the gas in the molding cavity.

[0008] The buffer structure includes a first groove and a second groove for buffering the medium, wherein the first groove is used to discharge gas from the molding cavity.

[0009] Preferably, the first groove is connected to the outside and the second groove, and the second groove is connected to the molding cavity.

[0010] Preferably, both the first module and the second module are provided with a support module, the support module is provided with a receiving groove, and the receiving groove is provided with a molding module that is detachably connected to the support module.

[0011] More preferably, the molding modules further include a positioning component, which is used to limit the position between the molding modules.

[0012] Preferably, the system further includes a guide component for guiding the opening and closing of the first module and the second module.

[0013] Preferably, the second module is further provided with an ejection mechanism, which is used to remove the formed cylinder end cap.

[0014] Preferably, when there are at least two molding cavities, the flow channel connects the casting port to each molding cavity.

[0015] The beneficial effects of this application are as follows:

[0016] (1) This application uses a buffer structure arranged around the molding cavity to quickly discharge the gas inside the mold, avoid the presence of gas in the molding cavity, ensure product quality, and improve production efficiency.

[0017] (2) Secondly, the first groove connects the outside to the second groove respectively, and the second groove connects to the molding cavity; when the medium is injected into the molding cavity, as the gas in the molding cavity is discharged, some of the medium will overflow along the second groove and the first groove. The second groove can buffer the medium, thereby avoiding a large amount of medium overflowing the mold and reducing the waste of the medium.

[0018] (3) Both the first module and the second module include a support module and a detachable molding module. Different molding modules can be replaced as needed to improve overall applicability and mold products of different specifications.

[0019] (4) Multiple molding cavities can be set as needed to mold multiple products at the same time, which can further improve production efficiency. Attached Figure Description

[0030] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described in this application are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0031] See Figures 1 to 5 To further elaborate on this application:

[0032] Combination Figure 5 A cylinder end cap die-casting mold includes an openable first module 10 and a second module 20, wherein the first module 10 and the second module 20 form at least one molding cavity A that matches the cylinder end cap 00; wherein the second module 20 may be fixedly installed, and the first module 10 may be driven by a power component to realize the opening and closing action; of course, both the first module 10 and the second module 20 may be driven by a power component, which is not limited here; the first module 10 and the second module 20 may be horizontally installed (e.g., Figure 2 (This can also be a setting method.)

[0033] Combination Figure 2 The first module 10 is provided with a casting port 40 for the medium to enter, and the casting port 40 is connected to the flow channel 50 of the molding cavity A. The medium can be molten aluminum, which is not limited here. The first module 10 and / or the second module 20 are provided with a plurality of buffer structures 30 arranged around the molding cavity A. The buffer structures 30 are connected to the outside and the molding cavity A and are used to discharge the gas in the molding cavity A. The buffer structure 30 includes a first groove 310 and a second groove 320 for buffering the medium. The first groove 310 is used to discharge the gas in the molding cavity A.

[0034] During operation, the medium is poured in through the casting port 40 and enters the molding cavity A through the flow channel 50 until all the gas in the molding cavity A is discharged (the molding cavity A is filled with medium). The gas in the molding cavity A is discharged through the buffer structure 30 and waits for cooling and molding.

[0035] Combination Figure 2 and Figure 4 In this embodiment, the first groove 310 is connected to the outside and the second groove 320, and the second groove 320 is connected to the molding cavity A. Therefore, when the medium gradually fills the molding cavity A, some of the medium will overflow from the first module 10 and the second module 20 through the buffer structure 30 (first groove 310 and second groove 320). The medium will first enter the second groove 320 to buffer and store the medium, preventing the medium from overflowing rapidly along the buffer structure 30, thereby reducing the amount of medium discharged and reducing the waste of medium.

[0036] Combination Figure 2 In some embodiments, the first groove 310 is curved to further reduce the amount of medium discharged without affecting the normal discharge of gas.

[0037] This application utilizes several buffer structures 30 arranged around the molding cavity A to quickly discharge gas from the molding cavity A, thereby ensuring the quality and yield of the produced cylinder end cap 00 and improving production efficiency. On the other hand, the buffer structures 30 can greatly reduce the amount of medium overflow, thereby reducing the waste of medium.

[0038] Combination Figures 3 to 5 In this embodiment, both the first module 10 and the second module 20 are provided with a support module 80. The support module 80 has a receiving groove, and a forming module 90 for detachable connection to the support module 80 is provided within the receiving groove. The first module 10 and the second module 20 have several through holes communicating with the receiving groove, and detachable connection is achieved through fastening components. Different forming modules 90 can be replaced as needed to cast cylinder end caps 00 of different specifications, resulting in better versatility.

[0039] Combination Figure 1 , 3 and Figure 4 It is understood that the cylinder end cap 00 includes a convex surface 001 and a concave surface 002; the first module 10 includes a first support module 80A and a first forming module 90A, the first forming module 90A being a cavity adapted to the convex surface 001 of the cylinder end cap 00; the second module 20 includes a second forming module 90B and a second support module 80B, the second forming module 90B being a protrusion adapted to the concave surface 002 of the cylinder end cap 00.

[0040] The molding modules 90 also include a positioning component 60, which is used to limit the position between the molding modules 90; this ensures the positional relationship between the molding modules 90 and improves production accuracy. The positioning component 60 includes a limiting member disposed on the first module 10 and a positioning member disposed on the second module 20; the limiting member can be a groove, and the positioning member can be a locking block; of course, the limiting member can also be disposed on the second module 20 and the positioning member on the first module 10, which is not limited here.

[0041] In some embodiments, a guide component 70 is further included, which guides the opening and closing of the first module 10 and the second module 20. The guide component 70 may include guide holes and guide posts that are coaxially disposed and cooperate with each other on the first module 10 and the second module 20, respectively.

[0042] In some embodiments, the second module 20 is further provided with an ejection mechanism for removing the formed cylinder end cap 00. The ejection assembly includes a push rod and a receiving hole on the second module 20, the push rod being disposed within the receiving groove. After the cylinder end cap 00 is formed, the first module 10 and the second module 20 are opened, and the push rod pushes the cylinder end cap 00 out of the second module 20.

[0043] In this embodiment, when there are at least two molding cavities A, the flow channel 50 connects the casting port 40 to each molding cavity A. Multiple molding cavities A can be provided as needed to simultaneously mold multiple cylinder end caps 00, further improving production efficiency.
