Description

Technical Field

[0001] This invention belongs to the technical field of four-sided forming metal connector processing molds, specifically relating to a four-sided forming metal connector, its casting device and casting method. Background Technology

[0002] Gravity casting and low-pressure casting are metal manufacturing processes characterized by utilizing the gravity of molten metal or flowing into a mold cavity under relatively low pressure. The molds are typically made of high-strength alloys. Due to the high cost of casting equipment and molds, gravity casting and low-pressure casting are generally only used for mass production of large quantities of products. Gravity casting and low-pressure casting are particularly suitable for manufacturing complex-shaped castings, making them among the most common casting processes. Compared to other casting technologies, castings produced by gravity casting and low-pressure casting can undergo T6 treatment and exhibit high mechanical properties.

[0003] In existing technologies, casting metal connectors with four-sided forming typically requires two side molds, allowing only one metal part to be processed at a time, resulting in low production efficiency. Furthermore, it generates a significant amount of waste, leading to low material yield and failing to meet the requirements of energy-saving and environmentally friendly production. Additionally, most existing technologies require the use of sand cores as molds, often necessitating core replacements and increasing production costs. Summary of the Invention

[0004] In view of this, the present invention provides a four-sided formed metal connector, its casting apparatus and casting method.

[0005] The technical solution of this invention is as follows:

[0006] A four-sided formed metal connector, characterized in that one end of the metal component is symmetrically provided with snap-fit ​​portions, an installation groove is provided between the snap-fit ​​portions, and mating grooves are provided on both sides of the snap-fit ​​portions; the other end of the metal component is symmetrically provided with mounting portions, and the mounting portions are provided with mounting holes.

[0007] The snap-fit ​​part, mounting groove, mating groove, mounting part, and mounting hole are integrally formed.

[0008] The present invention provides a casting device for metal connectors with four-sided forming, characterized in that it includes a processing plate, forming half molds symmetrically arranged on the processing plate, and forming cavities symmetrically arranged in the forming half molds;

[0009] It also includes a mold core, on both sides of which are symmetrically fitted with molding inserts;

[0010] A side molding is provided on one side of the molding insert;

[0011] It also includes a push rod, which is configured to correspond to the molding insert.

[0012] The molding cavity, molding insert, and side molding components work together to form the molding area.

[0013] A lifting assembly is connected below the top rod.

[0014] One side of the molding half is connected to a first driving component, and one side of the side molding part is connected to a second driving component.

[0015] The molded insert includes a connecting bevel, and the molded insert has a molded portion on the side away from the connecting bevel.

[0016] The forming part includes a forming groove, and forming protrusions are provided in the forming groove.

[0017] The forming groove is an H-shaped forming groove.

[0018] The mold core is fixedly connected to the processing plate.

[0019] The horizontal cross-section of the mold core is an isosceles trapezoid, and the connecting inclined surface is correspondingly fitted to the side surface of the mold core. The connecting inclined surface can move up and down along the side surface of the mold core. In this invention, the forming inserts are symmetrically arranged around the mold core, which can ensure the demolding and fastening effect of the internal clamping shape, allowing the overall casting mold core to move relatively, realizing the relative displacement or disassembly of the various components of the casting mold core, and effectively avoiding the generation of air holes inside the four-sided formed metal connectors produced.

[0020] In this invention, the mounting part and mounting hole are formed by the side molding part, the mating groove is formed on the side by the molding cavity, and the snap-fit ​​part and mounting groove are formed by the molding insert.

[0021] The present invention also provides a casting method for a four-sided formed metal connector, characterized by comprising the following specific steps:

[0022] S1. Place the molded insert on the side of the mold core and fix it in place;

[0023] S2. Connect the push rod to the lifting assembly, with the upper end of the push rod facing the molded insert;

[0024] S3. Control the first drive assembly to close the molding half mold; control the second drive assembly to make the side molding part enter the molding area;

[0025] S4. Pour heated molten metal into the feeding channel of the mold, so that the molten metal fills the forming area;

[0026] S5. Let stand for 30-120 seconds until the molten metal cools and solidifies.

[0027] S6. First, control the first drive assembly to demold the molding half mold; control the second drive assembly to make the side molding part exit into the molding area; at the same time, the lifting assembly drives the ejector rod to lift up, and the molding insert and the product are removed together; at this time, the molding insert and the product can be easily separated.

[0028] S7. Reset the lifting assembly and repeat steps S1-S6.

[0029] The molds of this invention are made entirely of metal materials, can be reused repeatedly, and can be assembled with existing mechanical devices, effectively improving production efficiency. At the same time, the molding inserts and side molding parts of this invention work together to replace the sand core molds in the prior art, making it green and environmentally friendly and reducing production costs. In addition, this invention can avoid defects caused by the use of sand cores in production, effectively improving the yield of finished products.

[0030] This invention is a mold for rapid one-time casting of metal connectors that can be formed on four sides. It has two forming areas and can produce two products at the same time, resulting in high production efficiency. At the same time, it improves the product yield, reduces the generation of production waste, and lowers production costs.

[0031] This invention employs a novel casting mold that can be reused for extended periods, enabling efficient production of four-sided formed metal connectors while ensuring the quality of the cast products. Attached Figure Description
