Description
Technical Field
[0001] The utility model relates to the field of die-casting molds, in particular to a multi-gate feeding structure for die-casting molds. Background Art
[0002] Conventional die-casting molds usually have only one gate structure. The gate structure is used to introduce molten metal so that the molten metal can be formed in the mold cavity. When the product is too large, in order to increase the injection speed of the molten metal, a multi-channel structure is often selected to achieve rapid injection. However, this method requires a greater injection pressure, and too large an injection pressure will reduce the product quality. To solve the above problems, a new gate structure needs to be designed to increase the flow rate of the molten metal. Summary of the Invention
[0003] The technical problem to be solved by the utility model is to provide a multi-gate feeding structure for die-casting molds, which has the characteristics of increasing the injection speed of molten metal, facilitating gate cutting, and ensuring product quality.
[0004] The technical solution adopted by the utility model to solve its technical problems is: to provide a multi-gate feeding structure for die-casting molds, including a gate plate, a mold plate, and a gate cutting structure. Two gate structures are arranged on the mold plate. A pouring gate structure is arranged in the middle of the front side of the gate plate. A runner structure is arranged between the pouring gate structure and the two gate structures. Gate cutting structures are installed on the left and right parts of the rear side of the gate plate, and one end of the gate cutting structure is inserted into the gate structure.
[0005] In this technical solution, two gate structures are set to form two aluminum liquid injection ports, which is convenient for quickly filling the mold cavity and ensuring the smooth forming of large products. The pouring gate structure is set to facilitate the injection of molten metal. The runner structure is set to facilitate the flow of molten metal. Two gate cutting structures are set to facilitate cutting the gate structure and facilitating product demolding.
[0006] As a supplement to this technical solution, a first guiding insert or a second guiding insert is installed in the gate structure, and the middle inner holes of the first guiding insert and the second guiding insert both adopt a conical structure with a smaller upper part and a larger lower part.
[0007] In this technical solution, the first guiding insert and the second guiding insert are set to facilitate the introduction of aluminum liquid, and the conical structure is set to facilitate the ejection of the ingot and the first guiding insert or the second guiding insert, facilitating the removal of the product.
[0008] As a supplement to this technical solution, a mold cavity is arranged in the middle of the lower side of the mold plate, and the mold cavity is docked with the two gate structures. The mold cavity is set to assist in product forming.
[0009] As a supplement to this technical solution, the nozzle cutting structure includes guiding pressing strips, a slider structure, and a cutting core-pulling mechanism. There are two guiding pressing strips arranged side by side. The two guiding pressing strips are embedded and installed on the upper end face of the mold plate. A slider structure is installed on the guiding pressing strips. A cutting core-pulling mechanism is installed at one end of the slider structure close to the nozzle structure. One end of the cutting core-pulling mechanism is docked with the nozzle structure. Two inclined guide pillars passing through the slider structure are arranged side by side on the slider structure. The upper ends of the inclined guide pillars are inclined towards the nozzle structure. By setting the inclined guide pillars, when the mold is opened, the slider structure can be pushed, so that the slider structure drives the cutting core-pulling mechanism, and the cutting core-pulling mechanism can be disengaged from the nozzle structure.
[0010] As a supplement to this technical solution, a cutting protrusion is provided at one end of the cutting core-pulling mechanism close to the nozzle structure. The cutting protrusion is in an arc-shaped strip shape and is arranged at the lower part of the end of the cutting core-pulling mechanism. By setting the cutting protrusion, a cutting opening is provided at the upper end of the nozzle structure, which facilitates quick disconnection at this place during demolding.
