AI Technical Summary
Existing die-casting molds have dynamic balance deviations that exceed design requirements when forming circular castings, resulting in unqualified castings. Furthermore, subsequent processing and adjustments are complex and costly.
A die-casting mold design employs a fixed mold core with radial dividing grooves and adjustment through holes, combined with an adjustment core and a calibration core. The adjustment core and calibration core are used to balance and compensate for the casting, ensuring that the casting meets the design requirements.
It improves the pass rate and production efficiency of castings, reduces production costs, avoids subsequent processing and adjustments, and enhances the dynamic balance accuracy of castings.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of die casting, in particular to a die casting die used for die casting to form circular castings. Background Art
[0002] According to design requirements, such as Figure 1 The circular casting 01 shown here is required to have a dynamic balance deviation within 0.1g. However, during a dynamic balance test, the dynamic balance deviation of one sector plate located in the same area of the circular casting 01, formed using an existing die-casting mold, exceeded the design requirement, causing the die-cast circular casting 01 to fail. Utility Model Content
[0003] In order to improve the qualified rate of circular castings, the present invention proposes a die-casting mold for circular castings, the die-casting mold comprising a fixed die core and an adjustment core, the fixed die core being provided with a fixed die cavity, the bottom of the fixed die cavity being provided with a plurality of radial dividing grooves and an adjustment through-hole, the adjustment through-hole being located between two adjacent radial dividing grooves and vertically connected to the bottom of the fixed die cavity; the adjustment core being inserted into the adjustment through-hole, and the adjustment end of the adjustment core extending into the fixed die cavity. In this way, when the circular casting is die-casted using the die-casting mold for circular castings of the present invention, the adjustment core inserted into the adjustment through-hole can be used to balance and compensate the circular casting to be die-cast, so that the circular casting formed by die-casting meets the design requirements and improves the qualified rate of the circular castings. In addition, when the circular casting is die-casted using the die-casting mold for circular castings of the present invention, after die-casting is completed, there is no need to adjust the dynamic balance deviation of the circular casting through subsequent processing, thereby improving the production efficiency of the circular casting and reducing the production cost of the circular casting.
[0004] Preferably, the adjustment through hole is close to the outer edge of the fixed die cavity. In this way, the adjustment core inserted in the adjustment through hole is close to the outer edge of the fixed die cavity, that is, close to the outer edge of the circular casting formed by die casting, which is convenient for adjustment.
[0005] Preferably, the fixed mold core is provided with two calibration through-holes, and calibration cores are inserted into the calibration through-holes. In this way, the calibration cores can be used in conjunction with the adjustment cores to balance and compensate the circular casting to be die-cast, thereby improving the dynamic balancing accuracy of the circular casting formed by die-casting. Furthermore, the calibration through-holes are located on either side of the adjustment through-hole, and the calibration through-holes are close to the radial dividing grooves located on either side of the adjustment through-hole. In this way, two calibration cores are provided on either side of the adjustment core to balance and compensate the circular casting to be die-cast in conjunction with the adjustment cores on both sides of the adjustment core, further improving the dynamic balancing accuracy of the circular casting formed by die-casting.
[0006] Preferably, the axial section of the adjusting through hole and the calibration through hole is a "convex" structure, and the bottom of the "convex" structure is located on the positioning surface of the mold core towards the mold plate. In this way, the adjusting core is clamped by the adjusting through hole close to the clamping table of the mold plate, and the calibration core is clamped by the calibration through hole close to the clamping table of the mold plate, so that the length of the adjusting core and the calibration core inserted into the mold cavity is not too long, and the two-stage dynamic balance precision of the round casting formed by pressure casting is affected.

[0010] Next, the die casting mold for round castings will be described in detail in combination with Figure 2 and 3 .
[0011] As Figure 2 and 3As shown, the die-casting die for circular castings of the utility model comprises a fixed mold core 1 and an adjusting core (not shown in the figure), and the fixed mold core 1 is provided with a fixed mold cavity 11, the bottom of the fixed mold cavity 11 is provided with a plurality of radial separation grooves 111 and adjusting through holes 112, the adjusting through holes 112 are located between two adjacent radial separation grooves 111, and the adjusting through holes 112 vertically communicate with the bottom of the fixed mold cavity 11; the adjusting core is inserted in the adjusting through hole 112, and the adjusting end of the adjusting core extends into the fixed mold cavity 11. In this way, when the die-casting die for circular castings of the utility model is used to form a circular casting by die-casting, the adjusting core inserted in the adjusting through hole 112 can be used to balance and compensate the circular casting to be die-cast, so that the circular casting formed by die-casting meets the design requirements, and the qualified rate of the circular casting is improved. In addition, when the die-casting die for circular castings of the utility model is used to form a circular casting by die-casting, after die-casting is completed, the dynamic balance deviation of the circular casting does not need to be adjusted through subsequent processing, the production efficiency of the circular casting is improved, and the production cost of the circular casting is reduced. Preferably, the adjusting through hole 112 is close to the outer edge of the fixed mold cavity 11. In this way, the adjusting core inserted in the adjusting through hole 112 is close to the outer edge of the fixed mold cavity 11, that is, close to the outer edge of the circular casting formed by die-casting, which is convenient for adjustment. Preferably, the fixed mold core 1 is provided with two calibration through holes 113, and calibration cores (not shown in the figure) are inserted in the calibration through holes 113. In this way, the calibration cores can be used to balance and compensate the circular casting to be die-cast in cooperation with the adjusting core, and the dynamic balance precision of the circular casting formed by die-casting is improved. Preferably, the calibration through holes 113 are located on both sides of the adjusting through hole 112, and the calibration through holes 113 are close to the radial separation grooves 111 located on both sides of the adjusting through hole 112. In this way, the two calibration cores are arranged on both sides of the adjusting core to balance and compensate the circular casting to be die-cast in cooperation with the adjusting core on both sides of the adjusting core, and the dynamic balance precision of the circular casting formed by die-casting is further improved. Preferably, the axial section of the adjusting through hole 112 and the calibration through hole 113 is a "convex" structure, and the bottom of the "convex" structure is located on the positioning surface of the fixed mold plate 2 facing the fixed mold plate 2. In this way, the adjusting core is clamped by the clamping table close to the fixed mold plate 2, and the calibration core is clamped by the clamping table close to the fixed mold plate 2, so that the length of the adjusting core and the calibration core extending into the fixed mold cavity 11 is not too long, and the dynamic balance precision of the circular casting formed by die-casting is affected.
